Or the access point is equivalent to a bridge connecting a wired network and a wireless network, and is mainly used for connecting all wireless network clients together and then connecting the wireless network into the Ethernet. In WLAN systems, an access point may be referred to as an access point station (AP STA). The device with the wireless communication function can be equipment of a whole machine, a chip, a processing system or a functional module and the like which are arranged in the equipment of the whole machine, and the equipment provided with the chip, the processing system or the functional module can realize the method, the function and the like of the embodiment of the application under the control of the chip, the processing system or the functional module. The AP in the embodiment of the application is a device for providing service for non-AP STA, and can support 802.11 series protocols or subsequent protocols and the like. For example, the access point may be an access point for a terminal (such as a mobile phone) to enter a wired (or wireless) network, and is mainly deployed in a home, a building, and a park, where a typical coverage radius is several tens meters to hundreds meters, and of course, may be deployed outdoors. For another example, the AP may be a communication entity such as a communication server, router, switch, bridge, etc., and the AP may include various forms of macro base stations, micro base stations, relay stations, etc. The AP may of course also be a chip or a processing system or a module in the above-mentioned various forms of devices, so as to implement the methods and functions of the embodiments of the present application.
An STA is a device with wireless communication functionality that supports communication or sensing or enabling using WLAN protocols, and has the ability to communicate or sense or enable with other non-AP STAs or access points in a WLAN network. In a WLAN system, a station may be referred to as a non-access point station (non-access point station, non-AP STA). For example, the STA is any user communication device that allows a user to communicate with an AP or sense or enable the AP to communicate with a WLAN, and the device with a wireless communication function may be a complete device, or may be a chip or a processing system or a functional module installed in the complete device, and the device on which the chip or the processing system or the functional module is installed may implement the methods and functions of the embodiments of the present application under the control of the chip or the processing system or the functional module. For example, the STA may be a wireless communication chip, a wireless sensor, a wireless communication terminal, or the like, and may also be referred to as a user. For another example, the STA may be a mobile phone supporting a Wi-Fi communication function, a tablet computer supporting a Wi-Fi communication function, a set top box supporting a Wi-Fi communication function, an intelligent television supporting a Wi-Fi communication function, an intelligent wearable device supporting a Wi-Fi communication function, a vehicle communication device supporting a Wi-Fi communication function, a computer supporting a Wi-Fi communication function, and the like. Of course, the STA may also be a chip or a processing system or a module in the above various forms of devices, so as to implement the methods and functions of the embodiments of the present application.
By way of example, a communication system to which the method provided by the embodiment of the present application may be applied may include an access point and a station. For example, the embodiments of the present application may be applicable to a scenario of communication or awareness between an AP and an STA, between an AP and an AP, or between an STA and an STA in a WLAN, which is not limited in this embodiment of the present application. Alternatively, an AP may communicate or sense with a single STA or with multiple STAs simultaneously. Specifically, the communication or sensing between the AP and the STAs may be further divided into downlink transmission in which the AP simultaneously transmits signals to the STAs, and uplink transmission in which the STAs transmit signals to the AP. Among them, WLAN communication protocols can be supported between the AP and the STA, between the AP and the AP, and between the STA and the STA, and the communication protocols may include IEEE802.11 series protocols, for example, may be applicable to 802.11bn protocols, and certainly, may also be applicable to protocols after 802.11 bn.

Meanwhile, the number of APs and the number of STAs shown in fig. 1 are only examples, and the number of APs or STAs may be more or less in a specific implementation, which is not limited in the embodiment of the present application.

As another example, the first communication device may be an AP and the second communication device may be a non-AP STA. As yet another example, the first communication device and the second communication device may both be non-AP STAs or both be APs. As yet another example, the first communication device may be a non-AP STA and the second communication device may be an AP. As yet another example, at least one of the first communication apparatus and the second communication apparatus may be a multi-link device (multi-LINK DEVICE, MLD) or the like, and embodiments of the present application are not listed one by one. By way of example, MLD means that the device has multiple stations (e.g., APs or non-AP STAs) simultaneously, each operating on a different frequency band or channel.

The method provided by the embodiment of the application is described by using the two sides of the first communication device and the second communication device, but the first communication device and the second communication device can also forward the signals through other devices in the process of transmitting the signals, for example, the signals between the first communication device and the second communication device are forwarded through the forwarding device, and the embodiment of the application is not limited to other devices except the first communication device and the second communication device.
The following describes terms or nouns involved in embodiments of the application.
1. Subcarrier planning (toneplan) based on resource units (resourceunit, RU)
As an example, when the bandwidth is 20MHz, the entire bandwidth (i.e., 20 MHz) may be composed of one entire 242-tone RU, or may be composed of various combinations of 26-tone RU,52-tone RU,106-tone RU. Fig. 2a is a schematic diagram of a 20MHz subcarrier distribution and RU distribution according to an embodiment of the present application. As shown in fig. 2a, 20MHz may include 9 26-tone RUs, or include 4 52-tone RUs, or include 2 106-tone RUs, or include 1 242-tone.
The 26-tone-RU is one RU including 26 subcarriers, the 52-tone RU is one RU including 52 subcarriers, the 106-tone RU is one RU including 106 subcarriers, the 242-tone RU is one RU including 242 subcarriers, and so on. Each RU may include data subcarriers and pilot subcarriers. Such as the data subcarriers may be used to carry data information, pilot subcarriers may be used for phase offset and/or frequency offset estimation, etc. The 20MHz bandwidth may include at least one of one or more guard (guard) subcarriers, one or more null (null) subcarriers, and one or more Direct Current (DC) subcarriers, in addition to RU. Reference may be made to related standards or protocols for subcarrier ranges (sub-carrier ranges) included in the respective RUs, which are not described in detail herein. The description herein regarding RU or subcarrier is equally applicable to other bandwidths shown below, and will not be repeated. The description herein regarding the subcarriers applies equally to the description of DRUs below, and will not be described in detail.
As another example, when the bandwidth is 40MHz, the entire bandwidth (i.e., 40 MHz) may be composed of one entire 484-tone RU, or may be composed of various combinations of 26-tone RU,52-tone RU,106-tone RU,242-tone RU. The overall bandwidth corresponds approximately to a copy of the 20MHz subcarrier plan. As shown in fig. 2b, 40MHz may include 18 26-tone RUs, or include 8 52-tone RUs, or include 4 106-tone RUs, or include 2 242-tone RUs, or include 1 484-tone RU.
As yet another example, when the bandwidth is 80MHz, the entire bandwidth (i.e., 80 MHz) may be composed of one entire 996-tone RU, or may be composed of various combinations of 26-tone RU,52-tone RU,106-tone RU,242-tone RU,484-tone RU. As shown in fig. 2c, 80MHz may include 36 26-tone RUs, or include 16 52-tone RUs, or include 8 106-tone RUs, or include 4 242-tone RUs, or include 2 484-tone RUs, or include 1 996-tone RU. Wherein 484L,484R represents the left half and the right half of a 484-tone RU, each containing 242 subcarriers, is another representation of 484+5DC. For example, taking the case that the subcarrier range of 484-tone RU is [ -500: -12], the "484L" is a low frequency portion with respect to the frequency center of the 484-tone RU, i.e., [ -500: -259], and the "484R" is a high frequency portion with respect to the frequency domain center of the 484-tone RU, i.e., [ -253: -12]. Similarly, for example, taking the subcarrier range of 484-tone RU as [12:500], 484L is [12:253], 484R is [259:500]. And are not listed here.
In the present application [ a: b ] may refer to all integers from a to b (a and b are also integers), i.e., a, (a+1), (a+2), (a+3),. B, and the description thereof will not be repeated. For example, [259:500] represents 259,260,261,262, 498,499,500. For another example, [ -500: -259] represents-500, -499, -498, -497.
As yet another example, when the bandwidth is 160MHz, the entire bandwidth may be considered as a duplicate of the distribution of two 80MHz subcarriers, e.g., the entire bandwidth may be composed of an entire 2 x 996-tone RU, or may be composed of various combinations of 26-tone RU,52-tone RU,106-tone RU,242-tone RU,484-tone RU,996-tone RU. When the bandwidth is 320MHz, the entire bandwidth can be seen as a replica of the four 80MHz subcarrier distributions. And are not listed here.
In the above various subcarrier schemes, the leftmost of fig. 2a to 2c may be the lowest frequency and the rightmost of fig. 2a to 2c may be the highest frequency in units of 242-tone RU (i.e., 20 MHz). From left to right, 242-tone RUs may be numbered first (1 st), second (2 nd), sixteenth (16 th). Taking 320MHz bandwidth as an example, the data (data) field in the radio frame may occupy at most 16 242-tone RUs, that is, there may be at most 16 242-tone RUs in the data field and 16 20MHz channels in one-to-one correspondence from low to high frequency.
In general, one STA may allow allocation of multiple RUs, that is, may allocate multiple RUs to one STA in a combined manner, and thus the 802.11be standard supports Multiple RU (MRU). In other words, the 802.11be standard includes some MRUs in addition to the several RU mentioned above. For example, one 52-tone RU and one 26-tone RU make up 52+26-tone MRU. For another example, one 106-tone RU and one 26-tone RU make up 106+26-tone MRU. For another example, one 996-tone RU and one 484-tone RU make up 996+484-tone MRU. For another example, two 996-tone RUs and one 484-tone RU make up a 2x 996+484-tone MRU. For another example, 3 996-tone RUs make up 3 x 996-tone MRU. For another example, 3 996-tone RUs and one 484-tone RU make up a 3 x 996+484-tone MRU. The symbol "x" in the present application means "multiplication" or "multiplication".
In the bandwidth level, when the subcarrier spacing is 78.125KHz, a 26-tone RU may correspond to approximately 2MHz (i.e., 26 x 78.125 khz= 2031.25khz≡2 MHz), a 52-tone RU corresponds to approximately 4MHz, a 106-tone RU corresponds to approximately 8MHz, and a 242-tone RU corresponds to approximately 20MHz. The sizes of other RUs can be analogized by corresponding additions or multiplications, and the application is not repeated.
The RU may be referred to as a regular RU (rRU). Such a conventional RU has a smaller bandwidth and a lower transmission power than a distributed RU. The "lower" is shown herein with respect to a distributed RU, as the transmission power of the distributed RU may be further increased with respect to a conventional RU.
2. Uplink multi-user transmission
Uplink multi-user transmission is an important technology. Referring to fig. 3a, fig. 3a is a schematic flow chart of uplink multi-user transmission according to an embodiment of the present application. As shown in fig. 3a, the uplink multi-user transmission process may include an AP sending a trigger frame for triggering uplink multi-user transmission, where the trigger frame carries identifier information and resource allocation information of one or more stations, and after receiving the trigger frame, each station sends an uplink data frame on an allocated Resource Unit (RU) by using a trigger-based physical layer protocol data unit (trigger based PHYSICAL LAYER protocol data unit, TB PPDU), and receives an acknowledgement (block acknowledge, BA) frame sent by the AP after a short inter-frame space (SIFS).
In one possible implementation, the trigger frame may include, but is not limited to, a public information field and a user information list field. The common information field may contain common information that all STAs of the trigger frame schedule need to read. In 802.11be, the user information list field of the trigger frame may include, but is not limited to, one or more EHT variant user information fields (EHTVARIANT USER INFO FIELD). An EHT variant user information field may contain information that an EHT STA needs to read. Referring to fig. 3b, fig. 3b is a schematic diagram of a frame format of an EHT variant user information field provided in an embodiment of the present application. As shown in fig. 3b, the EHT variant user information fields include, but are not limited to, a resource unit allocation subfield (RU Allocation subfield) and a master-slave 160 subfield (PS 160 subfield).
In general, the RU or MRU allocated by the STA may be indicated by a resource unit allocation subfield (RU Allocation subfield), a master-slave 160 subfield (PS 160 subfield), an upstream bandwidth subfield (UL BW subfield) in a common information field, or an upstream bandwidth extension subfield (UL BW extensionsubfield) in a special user information field. In the common information field, B55 indicates whether or not there is a special user information field in the user information field. For the EHT TB PPDU, its bandwidth is commonly determined by the UL BW subfield and the UL BW extension subfield in the special user information field.
The B0 bit in the RU allocated subfield, the B7 to B1 bits in the RU allocated subfield, the PS160 subfield, and the mapping relationship between RU and MRU are shown in table 1 below. Wherein the bandwidth is determined by both the UL BW subfield and the UL BW extension subfield. Table 1 shows the interpretation of RU allocation subfield and PS160 subfield in 802.11be trigger frame.
TABLE 1
In one possible implementation, N in table 1 may be obtained by the formula n=2xx1+x0. The values of X1 and X0 are shown in Table 2 below, and Table 2 shows a look-up table of X1 and N (Lookup table for X and N).
TABLE 2
P80 in table 2 represents a master 80MHz channel, S80 represents a slave 80MHz channel, and S160 represents a slave 160MHz channel.
Wherein the configuration in the above table 2 refers to the order of P80, S80, and S160 in absolute frequency, and sequentially indicates from low frequency to high frequency from left to right. For example, [ P80S 80] indicates that the primary 80MHz channel is the first 80MHz channel from low to high frequency and the secondary 80MHz channel from low to high frequency, or [ P80S 80] indicates that the primary 80MHz channel is the low 80MHz channel and the secondary 80MHz channel is the high 80MHz channel. As another example, [ S80P 80S 160] means that the slave 80MHz channel is a low 80MHz channel of the low 160MHz channels, the master 80MHz channel is a high 80MHz channel of the low 160MHz channels, and the slave 160MHz channel is a high 160MHz channel.
3. Distributed resource units
Recently, the federal communications commission issued regulations on the 6GHz spectrum, defining a low power in-house (LPI) mode of communication, severely limiting the maximum power and maximum frequency spectral density transmitted. For example, for Station (STA), the maximum power is 24dBm and the maximum power spectral density is-1 dBm/MHz. The transmission power of the device is limited by both the maximum power and the maximum power spectral density, and first the transmission power cannot exceed the maximum power value and the transmitted power spectral density cannot exceed the maximum power spectral density. The maximum power spectral density is more severely limited than the maximum power, and the maximum power allowed to be transmitted is typically more limited by the power spectral density. For a station, the maximum power limit specified by the regulations is only reached when the bandwidth is 320MHz maximum. Below this bandwidth, lower power can only be transmitted, all because of the limitation of the maximum power spectral density. For 2021, 6 and 30 days, europe also promulgates regulations for the 6GHz spectrum, and for LPI communication modes, for example, the maximum power is 23dBm and the maximum power spectral density is 10dBm/MHz. The transmit power of the AP/STA is limited mainly by the power spectral density when the bandwidth does not exceed 20MHz, and the transmit power of the AP/STA is limited mainly by the maximum power when the bandwidth is greater than 20 MHz.
Because of the limited power spectral density, the number of limited subcarriers (e.g., 26-tone RU) is scattered to a wider bandwidth, i.e., more subcarriers (e.g., on odd subcarriers of 2 26-tone RU), so that the increase of the transmission power, i.e., the scattered RU, or the distributed RU can be obtained. In uplink multi-user transmission, a plurality of users are used for alternately transmitting discrete RUs, and the transmission power of each user is improved under the condition of a certain bandwidth. The maximum power spectral density is limited so that the transmission power of 1MHz does not exceed x mw, and 12.8 (about 13) subcarriers are included in 1MHz, considering a carrier interval of 78.125 kHz. Since the average power per subcarrier is the same during one transmission. Observing any of the consecutive 13 sub-carriers, including the maximum of the number of sub-carriers carrying the signal, will determine the average power per sub-carrier and thus the transmit power of the signal. For example, at 20M bandwidth (242 total subcarriers), up to 5 subcarriers are included in all 13 consecutive subcarriers, and then the average power per subcarrier will be x (mw)/5. Considering that there are 26 total subcarriers carrying a signal, the total transmit power will be x (mw)/5 x 26.
The meta DRU in the present application includes a plurality of sub-carriers scattered in a frequency domain, or includes a plurality of sub-carriers scattered with indexes (or referred to as index values), or includes a plurality of sub-carriers with indexes being discontinuous. The discrete plurality of subcarriers may be partially or completely discrete. As the discrete plurality of subcarriers may include a portion of the subcarriers being contiguous in frequency and a portion of the subcarriers being non-contiguous in frequency. As another example, the discrete plurality of subcarriers may also be completely discontinuous in frequency. The above-described "continuous in frequency" may also be referred to as continuous between indexes of subcarriers, and "discontinuous in frequency" may also be referred to as discontinuous between indexes of subcarriers. In the present application, a "distributed RU" or a "DRU" or a "discrete RU" may be used interchangeably. It should also be understood that DRUs mentioned in the present application refer to RU with sub-carriers scattered in the frequency domain, that is, RU with this characteristic, and the present application is referred to as distributed RU or discrete RU, but in practice RU with this characteristic may have other names, and the present application is not limited thereto.
The continuous RU in the present application refers to an RU consisting of a continuous plurality of subcarriers, or a continuous RU consisting of two continuous subcarrier groups, each of which includes a plurality of subcarriers that are continuous, and between which only subcarriers, null subcarriers, or direct current subcarriers are protected. Of course, the consecutive RU may be other names, such as regular RU (rRU), and "consecutive RU" and "regular RU" may be used interchangeably, and the present application is not limited to the names of consecutive RU.
The method provided by the embodiment of the application is described below.
Fig. 4 is a flow chart of a communication method according to an embodiment of the present application. The description of the first communication device and the second communication device referred to in fig. 4 may be referred to above and will not be described in detail here. As shown in fig. 4, the method includes:
401. the first communication device generates OFDM symbols.
402. The first communication device transmits OFDM symbols according to subcarrier planning corresponding to the first bandwidth.
Correspondingly, the second communication device receives the OFDM symbols according to the subcarrier planning corresponding to the first bandwidth.
403. The second communication device parses the OFDM symbol.
The first bandwidth is 160MHz, and the subcarrier planning corresponding to the first bandwidth comprises 996-tone DRU 1 and 996-tone DRU 2, 484-tone DRU 1-484-tone DRU 4, 242-tone DRU 1-242-tone DRU 8, or 106-tone DRU 1-106-tone DRU 16.
Wherein 996-tone DRU represents DRU including 996 subcarriers, 484-tone DRU represents DRU including 484 subcarriers, 242-tone DRU represents DRU including 242 subcarriers, and 106-tone DRU represents DRU including 106 subcarriers.
One 996-tone DRU may be divided into two 484-tone DRUs, one 484-tone DRU may be divided into two 242-tone DRUs, and one 242-tone DRU may be divided into two 106-tone DRUs.
For example, for different DRU sizes under the same bandwidth, the index of each DRU may have the following relationship:
242-tone DRU1 may comprise 106-tone DRU 1+106-tone DRU 2,242-tone DRU 2 may comprise 106-tone DRU 3+106-tone DRU 4,242-tone DRU 3 may comprise 106-tone DRU 5+106-tone DRU 6, and so on, 242-tone DRU 7 may comprise 106-tone DRU 13+106-tone DRU 14, and 242-tone DRU 8 may comprise 106-tone DRU15+106-tone DRU 16;
484-tone DRU 1 may comprise 242-tone DRU 1+242-tone DRU 2,484-tone DRU 2 may comprise 242-tone DRU 3+242-tone DRU 4,484-tone DRU 3 may comprise 242-tone DRU 5+242-tone DRU 6,484-tone DRU 4 may comprise 242-tone DRU 7+242-tone DRU 8;
996-tone DRU 1 may comprise 484-tone DRU 1+484-tone DRU 2,996-tone DRU 2 may comprise 484-tone DRU 3+484-tone DRU 4.
For a description of the subcarrier planning corresponding to the first bandwidth, reference may be made to the following, which will not be described in detail here. The numbers in the present application are for distinguishing between different DRUs, and are not meant to limit the present application.
Generally, the index range (subcarrier index range) of the subcarriers may be used to represent the locations of the subcarriers in the subcarrier plan corresponding to the first bandwidth in the frequency domain. For an index range, the middle index may be 0, the right of 0 may be +1, the left of 0 may be-1, the number of subcarriers included to the left of 0 (also understood as the index range), and the number of subcarriers included to the right of 0 (also understood as the index range) may be determined by the total number of subcarriers. When the total number of subcarriers is an odd number greater than 1, the number of subcarriers included to the left of 0 and the number of subcarriers included to the right of 0 may be the same. And when the total number of subcarriers is an even number greater than 2, the number of subcarriers included on the left of 0 and the number of subcarriers included on the right of 0 may be different. In general, the number of subcarriers included on the right of 0 may be smaller than the number of subcarriers included on the left of 0. But the present application is not limited thereto.
The index range involved in the subcarrier planning corresponding to the first bandwidth may be determined according to the first bandwidth and the subcarrier spacing. For example, with a subcarrier spacing of 78.125KHz, 160MHz may have 2048 (i.e., 160MHz/78.125 khz=2048) subcarriers. Taking the example of the number of subcarriers included to the left of 0 being greater than the number of subcarriers included to the right of 0, the index range of these 2048 subcarriers may be [ -1024:1023]. Alternatively, the 2048 subcarriers may have an index of [ -1024:1023] from low to high in frequency. Of course, as the standard progresses, the subcarrier spacing may also change, and when the subcarrier spacing changes, the number of subcarriers and the subcarrier index of each DRU in the present application may also change. No matter how the subcarrier spacing changes, the method for determining the index of each DRU is the same as the following, and the method belongs to the protection scope of the embodiment of the application.
In the embodiment of the application, the subcarrier planning corresponding to 160MHz is designed in detail, and each DRU under the subcarrier planning can achieve larger power amplification factor and improve the transmitting power of the communication device.
Subcarrier planning according to the embodiment of the application is described below.
Four subcarrier schemes are provided below for 160MHz, and in a specific implementation, the standard may define one subcarrier scheme or two subcarrier schemes, etc., which are not limited in this embodiment of the present application. For any one of the subcarrier plans, the standard may directly define the index of 2 996-tone DRUs, the index of 4 484-tone DRUs, the index of 8 242-tone DRUs, and the index of 106-tone DRUs at 160 MHz. Or the standard may also give index expressions of different DRUs, etc., and the application is not limited to the specific mode of the standard.
First subcarrier planning:
in one possible implementation, the subcarrier plan corresponding to the first bandwidth may include a first guard region, a first data pilot region, a first direct current region, a second data pilot region, a second direct current region, a third data pilot region, a third direct current region, a fourth data pilot region, and a second guard region.
The subcarriers in the first protection region and the second protection region may be protection subcarriers, and the subcarriers in the first dc region and the third dc region may be direct current subcarriers. In general, the subcarriers in the second dc region may be dc subcarriers, but the present application is not limited thereto. The first, second, third and fourth data pilot regions may include data subcarriers and pilot subcarriers therein. Alternatively, the four data pilot regions may include null (null) subcarriers. The names of the above-described respective areas are merely examples, and should not be construed as limiting the embodiments of the present application.
The first data pilot region may be located between the first protection region and the first direct current region, the second data pilot region may be located between the first direct current region and the second direct current region, the third data pilot region may be located between the second direct current region and the third direct current region, and the fourth data pilot region may be located between the third direct current region and the second protection region. Fig. 5a is a schematic diagram of region division according to an embodiment of the present application. Fig. 5a shows exemplary frequency domain locations of the various regions described above.
The embodiment of the application designs DRU with different sizes in the first data pilot frequency area, the second data pilot frequency area, the third data pilot frequency area and the fourth data pilot frequency area. For example, for the four data pilot regions, 2 996-tone DRUs (e.g., 996-tone DRU 1 and 996-tone DRU 2), 4 484-tone DRUs (e.g., 484-tone DRU 1, 484-tone DRU 2, 484-tone DRU 3 and 484-tone DRU 4), 8 242-tone DRUs (e.g., 242-tone DRU 1 to 242-tone DRU 8), and 16 106-tone DRUs (e.g., 106-tone DRU 1 to 106-tone DRU 16) are respectively designed in the embodiment of the present application. The DRUs of different sizes may be a single embodiment, or the DRUs of different sizes may be combined into one embodiment, which is not limited by the present application. The following detailed description:
1A、996-tone DRU
996-tone DRU 1 may satisfy the following conditions:
The 996-tone DRU 1 is distributed in a first data pilot region, a second data pilot region, a third data pilot region and a fourth data pilot region, and the 996-tone DRU 1 comprises even-numbered subcarriers in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region.
996-Tone DRU 1 may satisfy the following conditions:
The condition 2:996-tone DRU 2 is distributed in a first data pilot region, a second data pilot region, a third data pilot region and a fourth data pilot region, and the 996-tone DRU 2 comprises subcarriers with odd indexes in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region.
As an example, the first to fourth data pilot regions may not include null subcarriers. The total number of subcarriers in these four data pilot regions is 996×2=1992. In other words, the total number of subcarriers in the first, second, first, and third direct current regions is 2048-1992=56.
As another example, the first to fourth data pilot regions may include null subcarriers therein. The total number of remaining subcarriers except for null subcarriers in the four data pilot regions may be 1992, for example. In other words, the total number of subcarriers in the first, second, first, and third direct current regions may be less than 56.
The descriptions of the respective areas are also applicable to 1b to 1d below, and are not repeated herein.
In the present application, for convenience of subsequent reference, when conditions satisfied by DRUs are referred to, different conditions satisfied by different DRUs are distinguished by different numbers, but they should not be construed as limiting the embodiments of the present application.
996-Tone DRU 1 may satisfy the following conditions:
Condition 3:996-tone DRU 1 has an index of the last subcarrier in the first data pilot region that differs from its index of the first subcarrier in the second data pilot region by an integer multiple of 2, has an index of the last subcarrier in the second data pilot region that differs from its index of the first subcarrier in the third data pilot region by an integer multiple of 2, and has an index of the last subcarrier in the third data pilot region that differs from its index of the first subcarrier in the fourth data pilot region by an integer multiple of 2.
In other words, the difference between the index of the last subcarrier of 996-tone DRU 1 in the first data pilot region and the index of the first subcarrier thereof in the second data pilot region is an integer multiple of the difference between the index of the last subcarrier thereof in the second data pilot region and the index of the first subcarrier thereof in the third data pilot region is an integer multiple of the difference between the index of the last subcarrier thereof in the third data pilot region and the index of the first subcarrier thereof in the fourth data pilot region is an integer multiple of the difference between the index of the last subcarrier thereof in the same data pilot region and the index of the adjacent subcarrier thereof in the same data pilot region.
The difference between the index of the last subcarrier in the first data pilot region (i.e., the end index in the first data pilot region) of the 996-tone DRU 1 and the index of the first subcarrier in the second data pilot region (i.e., the start index in the second data pilot region) may be 2,4,6,8,10,12,14,16,18 or 20, etc., which are not listed here.
The difference between the index of the last subcarrier in the first data pilot region and the index of the first subcarrier in the second data pilot region, the difference between the index of the last subcarrier in the second data pilot region and the index of the first subcarrier in the third data pilot region, and the difference between the index of the last subcarrier in the third data pilot region and the index of the first subcarrier in the fourth data pilot region of 9996-tone DRU 1 are 2, and the embodiment of the present application is not limited as to whether the above differences are the same.
996-Tone DRU 2 may satisfy the following relationship:
Condition 4:996-tone DRU 2 has an index of the last subcarrier in the first data pilot region that differs from its index of the first subcarrier in the second data pilot region by an integer multiple of 2, has an index of the last subcarrier in the second data pilot region that differs from its index of the first subcarrier in the third data pilot region by an integer multiple of 2, and has an index of the last subcarrier in the third data pilot region that differs from its index of the first subcarrier in the fourth data pilot region by an integer multiple of 2.
For the description of condition 4, reference is made to condition 3, which will not be described in detail here.
In the embodiment of the application, the 996-tone DRU 1 or the 996-tone DRU 2 can ensure that the peak average power ratio (peak to average power ratio, PAPR) of the 996-tone DRU is lower by meeting the conditions in the data pilot frequency region.
Under the condition that the condition is met, the index of 996-tone DRU can be designed in four data pilot frequency areas in subcarrier planning, so that the power amplification factor can be improved, and the PAPR can be ensured to be lower.
As one possible implementation 1, the first data pilot region has an index of [ -1012: -515], the second data pilot region has an index of [ -509: -12], the third data pilot region has an index of [12:509], and the fourth data pilot region has an index of [515:1012].
Since the index of the first subcarrier in the first data pilot region is even, the index of the first subcarrier in the second data pilot region is odd, the index of the first subcarrier in the third data pilot region is even, and the index of the first subcarrier in the fourth data pilot region is odd, the above 996-tone DRU 1 includes the even-numbered subcarriers in the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region, and may be replaced with 996-tone DRU 1 including the odd-numbered subcarrier in the first data pilot region, the even-numbered subcarrier in the second data pilot region, the odd-numbered subcarrier in the third data pilot region, and the even-numbered subcarrier in the fourth data pilot region. Similarly, 996-tone DRU 2 includes an even number of subcarriers in the first data pilot region, an odd number of subcarriers in the second data pilot region, an even number of subcarriers in the third data pilot region, and an odd number of subcarriers in the fourth data pilot region.
The index of the first protection area may be [ -1024: -1013] and the index of the second protection area [1013:1023]. Namely, according to the frequency from low to high, the 1 st to 12 th subcarriers in 2048 subcarriers are guard subcarriers, and the 2038 th to 2048 th subcarriers are guard subcarriers.
The first DC sub-region may have an index of [ -514:510 ], the second DC region has an index of [ -11:11], and the third DC region has an index of [510:514]. That is, the 511 th to 515 th subcarriers among 2048 subcarriers are dc subcarriers, the 1014 th to 1036 th subcarriers are dc subcarriers (or referred to as guard subcarriers), and the 1535 th to 1539 th subcarriers are dc subcarriers.
In the embodiment of the application, each area is divided by the above dividing manner, so that each data pilot area in the four data pilot areas can comprise 498 subcarriers, and the number of subcarriers in the four data pilot areas of 996-tone DRU 1 or 996-tone DRU 2 can be 249, so that the 498 subcarriers in each data pilot area can be used for designing 996-tone DRU, and the utilization efficiency of the subcarriers is improved.
Of course, the index ranges of the respective areas listed in the above embodiment 1 are merely examples, and in a specific implementation, the index range of at least one of the first protection area, the second direct current area, the second protection area, the first direct current area, or the third direct current area may be smaller, which is not limited by the embodiment of the present application. When the index range of at least one of the first protection region, the second protection region, the first dc region, the second dc region, or the third dc region is smaller, the index ranges of the first data pilot region to the fourth data pilot region may be larger, and at this time, the four data pilot regions may include null subcarriers.
In this disclosure, for convenience of subsequent reference, different implementations are therefore distinguished by numbering, but should not be construed as limiting embodiments of the present disclosure.
In combination with the condition 1 or the condition 3 satisfied by the 996-tone DRU1 and the indexes of the respective areas shown in the implementation mode 1, the embodiment of the application also provides the index of the 996-tone DRU1, as follows:
The subcarrier index of 996-tone DRU 1 is [ -1012:2: -516, -508:2: -12,12:2:508,516:2:1012]. The subcarrier index of the 996-tone DRU 1 is [ -1012, -1010, -1008, ], -518, -516, -508, -506, ], -14, -12,12,14,16, ], 506,508,516,518, ], 1010,1012].
In the present application [ a: x: b ] may represent an integer in increments of x from a to b, i.e., a, (a+x), (a+2x), (a+3x), and b. If [ -1012:2: -516] represents-1012, (-1012+2= -1010), (-1012+2 x 2= -1008),...
In combination with the condition 2 or the condition 4 satisfied by the 996-tone DRU 2 and the indexes of the respective areas shown in the implementation mode 1, the embodiment of the present application also provides the index of the 996-tone DRU 2, as follows:
The subcarrier index of 996-tone DRU 2 is [ -1011:2: -515, -509:2: -13,13:2:509,515:2:1011]. The subcarrier index of the 996-tone DRU 2 is [ -1011, -1009, -1007, ] -517, -515, -509, -507, ] -15, -13,13,15,17, ] -507,509,515,517, ] -1009,1011.
As can be seen from the above indices, for 996-tone DRU 1, the index of the last subcarrier in the first data pilot region is-516, and the index of the first subcarrier in the second data pilot region is-508, -508- (-516) =8, i.e. the index difference is 8. The index of the last subcarrier in the second data pilot region is-12, the index of the first subcarrier in the third data pilot region is 12, and the index difference is 24 (12- (-12) =8). The index of the last subcarrier in the third data pilot region is 508, the index of the first subcarrier in the fourth data pilot region is 516, and the index difference is 8 (516-508=8). Meanwhile, for 996-tone DRU 1, the index difference of adjacent subcarriers in each data pilot region is 2. That is, the index of the 996-tone DRU satisfies the above condition 1 and condition 3. Similarly, 996-tone DRU 2 satisfies the above condition 2 and condition 4.
In the embodiment of the application, 996-tone DRU 1 or 996-tone DRU 2 is uniformly distributed in four data pilot frequency areas, which is more beneficial to channel smoothing. Meanwhile, by satisfying the above condition 3 or condition 4, a low PAPR can be ensured. In the embodiment of the application, the power amplification factor achieved by the 996-tone DRU can be 2.69dB. For specific calculation methods reference may be made to the above terminology for distributed resource units.
1B、484-tone DRU
484-Tone DRU 1, 484-tone DRU 2, 484-tone DRU 3, 484-tone DRU 4 are all distributed over the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region. That is, 484-tone DRU 1 is distributed over the four data pilot regions, 484-tone DRU 2 is distributed over the four data pilot regions, 484-tone DRU 3 is distributed over the four data pilot regions, and 484-tone DRU 4 is distributed over the four data pilot regions.
484-Tone DRU 1-484-tone DRU 4 satisfies at least one of the following conditions:
The index difference of adjacent subcarriers of any one 484-toneDRU of 484-tone DRUs 1 to 484-tone DRUs 4 distributed in the first data pilot region is 4, the index difference of adjacent subcarriers of any one 484-tone DRU distributed in the second data pilot region is 4, the index difference of adjacent subcarriers of any one 484-tone DRU distributed in the third data pilot region is 4, and the index difference of adjacent subcarriers of any one 484-tone DRU distributed in the fourth data pilot region is 4.
Or, for any 484-tone DRU of 484-tone DRU 1-484-tone DRU 4, the index difference of adjacent subcarriers distributed in each data pilot region is 4.
For example, the subcarrier indexes are 1,5,9, and 13, and then 1 and 5 may be called adjacent subcarriers, or 5 and 9 may be called adjacent subcarriers, or 9 and 13 may be called adjacent subcarriers. The subcarrier index shown here is only an example and does not represent the subcarriers in the 484-tone DRU shown in the embodiment of the present application.
In the embodiment of the application, 484-tone DRU can achieve larger power amplification factor, such as 5.12dB, by meeting the condition 1.
The conditions 2:484-tone DRU 1, 484-tone DRU 2, 484-tone DRU 3, 484-tone DRU 4 are consecutive.
Illustratively, the p-th subcarrier in 484-tone DRU 1, the p-th subcarrier in 484-tone DRU 3, the p-th subcarrier in 484-tone DRU 2, and the p-th subcarrier in 484-tone DRU 4 are consecutive in order. Of course, the order shown here is merely an example, and as the number of 484-tone DRUs changes, the order shown here also changes, and the present application is not limited thereto.
Wherein p may be a positive integer less than or equal to 484. That is, the value of p may be the same as the number of subcarriers in the DRU. When the lowest frequency subcarrier is referred to as the 0 th subcarrier in order of the frequencies from low to high, the value of p may be an integer greater than or equal to 0 and less than 484. The present application is not limited to the specific value range of p. The description of p applies here to the following, and will not be repeated here.
In the embodiment of the application, 484-tone DRU can ensure that four 484-tone DRU form an integral translation relationship by meeting the condition 2, thereby being beneficial to the storage and reading of indexes. Meanwhile, the PAPR of 4 484-tone DRU is the same for the same LTF sequence, so that 4 484-tone DRU can share the same sequence, and sequence design is simplified.
For example, the 484-tone DRU described above may also satisfy the following condition 3:
any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the first data pilot region;
any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the second data pilot region;
Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the third data pilot region;
Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the fourth data pilot region.
Since 120×2+122×2=484, it may include 120 subcarriers (or 122 subcarriers) in any two of the four data pilot regions described above for any one 484-tone DRU, which includes 122 subcarriers (or 120 subcarriers) in the remaining two data pilot regions. For example, the number of subcarriers belonging to different 484-tone DRUs in the same data pilot region may be the same for different 484-tone DRUs.
As one example 1, any one 484-tone DRU may include 120 subcarriers in the first and second data pilot regions, which includes 122 subcarriers in the third and fourth data pilot regions. The example numbers shown herein are for convenience of reference and should not be construed as limiting embodiments of the application.
As another example 2, any one 484-tone DRU may include 120 subcarriers in the first and third data pilot regions, and 122 subcarriers in the second and fourth data pilot regions.
As yet another example 3, any one 484-tone DRU may include 120 subcarriers in the first data pilot region and the fourth data pilot region, and 122 subcarriers in the second data pilot region and the third data pilot region.
As yet another example 4, any one 484-tone DRU may include 122 subcarriers in the first and second data pilot regions, which include 120 subcarriers in the third and fourth data pilot regions.
As yet another example 5, any one 484-tone DRU may include 122 subcarriers in the first and third data pilot regions, and 120 subcarriers in the second and fourth data pilot regions.
As yet another example 6, any one 484-tone DRU may include 122 subcarriers in the first data pilot region and the fourth data pilot region, which may include 120 subcarriers in the second data pilot region and the third data pilot region.
In the embodiment of the application, the 484-tone DRU can enable the p-th subcarrier of each 242-tone DRU corresponding to the 484-tone DRU to be continuous by meeting the condition 3 and designing the 242-tone DRU according to the 484-tone DRU, and p is [1,242], so that each 242-tone DRU forms an integral translation relationship, and the index storage and reading are facilitated.
For example, the 484-tone DRU described above may also satisfy the following condition 4:
For any one 484-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 4, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of 4, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of 4.
In other words, for any one 484-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region (i.e., 4), the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region.
For example, for any 484-tone DRU, the difference between its index of the last subcarrier in the first data pilot region and its index of the first subcarrier in the second data pilot region may be 4,8,12,16,20,24,28 or 32, etc., which are not listed here.
For any one 484-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region, the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region, whether or not the above differences are the same, the embodiment of the present application is not limited.
In the embodiment of the application, the 484-tone DRU can ensure that the PAPR of the 484-tone DRU is lower by meeting the condition 4.
For example, the 484-tone DRU described above may also satisfy the following condition 5:
for either 484-tone DRU, 120 or 122 subcarriers in the first data pilot region may be shifted within the first data pilot region, or 120 or 122 subcarriers in the second data pilot region may be shifted within the second data pilot region, or 120 or 122 subcarriers in the third data pilot region may be shifted within the third data pilot region, or 120 or 122 subcarriers in the fourth data pilot region may be shifted within the fourth data pilot region.
The description of translation may also refer to the various index expressions shown below. For example, 484-tone DRU may satisfy the above condition 5 in the case of satisfying the above condition 1 to condition 4. In a specific implementation, a 484-tone DRU may determine one index from a plurality of different indexes of 4 484-tone DRUs if the above condition 5 is satisfied. An index may be defined as an index of 484-tone DRUs as a standard, or an index expression shown below may be defined, which is not limited by the embodiment of the present application.
In the embodiment of the application, the index of 484-tone DRU can be designed in four data pilot frequency areas under the condition that the conditions 1-4 are satisfied.
As one possible implementation, the first data pilot region has an index of [ -1012: -515], the second data pilot region has an index of [ -509: -12], the third data pilot region has an index of [12:509], and the fourth data pilot region has an index of [515:1012].
The index descriptions of the first protection region, the second dc region, the second protection region, the first dc region, and the third dc region may refer to the above implementation 1, and are not repeated here.
Under the four data pilot frequency areas, 4 484-tone DRU can be designed under the condition that the conditions 1-4 or the conditions 1-5 are met. As an example, under the four data pilot regions described above, 4 484-tone DRUs may be independently designed. As another example, under the four data pilot regions described above, 4 484-tone DRUs may be designed in conjunction with the index of the 996-tone DRUs shown above. The index of 484-tone DRUs will be described below in connection with the 2 996-tone DRUs shown above. With respect to the relationship of 484-tone DRUs to 996-tone DRUs, reference is made to the description of fig. 4, and will not be described in detail herein.
A number of possibilities for indexing the individual 484-tone DRUs are presented below.
For a first data pilot region:
In the case where any 484-tone DRU includes 120 subcarriers in the first data pilot region, the index may be expressed as:
484-tone DRU 1 index 120 subcarriers in the first data pilot region as
484-Tone DRU 2 index 120 subcarriers in the first data pilot region as
484-Tone DRU 3 index 120 subcarriers in the first data pilot region as
484-Tone DRU 4 index 120 subcarriers in the first data pilot region as
Wherein, the
In an embodiment of the present application,May be referred to as a translation value (or offset value or offset, etc.), which may be an integer. Illustratively, in the case where the start index in the expression shown in the present application is the start index of one data pilot region, the minimum value may be 0 and the maximum value may be determined based on the index of the last subcarrier of the aforementioned one data pilot region. In designing 484-tone DRUs from 996-tone DRUs, 484-tone DRUs can translate within the index range of 996-tone DRUs. In the case of 484-tone DRU 1 and 484-tone DRU 2 in combination with 996-tone DRU 1 designs, the range over which 484-tone DRU 1 can translate, and the range over which 484-tone DRU 2 can translate are each less than or equal to the index range of 996-tone DRU 1. For example, the maximum of the above-described translation values for 484-tone DRU 1 (or 484-tone DRU 2) may be determined based on the end index of 996-tone DRU 1. Further, the shift value of 484-tone DRU 1 in the first data pilot region may be determined based on the above condition 1-4 and the index of 996-tone DRU 1 in the last subcarrier in the first data pilot region. In the same way, the followingMay be an integer. The maximum value may be determined based on the index of the last subcarrier of the 996-tone DRU in the corresponding data pilot region, as the minimum value may be 0. The method for determining the maximum value (or the minimum value) of each shift value in the second subcarrier planning, the third subcarrier planning and the fourth subcarrier planning is similar, and will not be described in detail. The various expressions shown in the embodiments of the present application are merely examples and should not be construed as limiting the embodiments of the present application. As in other expressions, the translation value may also be negative and is not listed here.
Illustratively, in the case of different sized DRUs combining with each other to design indexes, as in the case of combining 484-tone DRU design 242-tone DRU, as in the case of combining 996-tone DRU design 242-tone DRU, as in the case of combining 242-tone DRU design 106-toneDRU, as in the case of combining 484-tone DRU design 106-tone DRU (not listed here), each shift value in the present application needs to satisfy at least one of (1) for any size DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of the index difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of the index difference between the index of its adjacent subcarrier and the index of its fourth subcarrier in the third data pilot region; the method comprises the steps of (1) setting a translation value of 484-tone DRU to be equal to a translation value of 242-tone DRU, (2) setting a translation value of 106-tone DRU to be equal to a translation value 8k of 484-tone DRU, wherein k is a positive integer. In addition to the above conditions, each translation value needs to satisfy the conditions satisfied by the corresponding DRU.
In the present application,The value may correspond to the first data pilot region, and 120 subcarriers. That is, "1" or "2" in the subscript can distinguish 120 or 122, and "1" to "4" in the superscript can represent the number of the region. For this description, various embodiments of the application apply.
In the case where any 484-tone DRU includes 122 subcarriers in the first data pilot region, the index may be expressed as:
484-tone DRU 1 index 122 subcarriers in the first data pilot region as
The index of 122 subcarriers of 484-tone DRU 2 in the first data pilot region is
484-Tone DRU 3 index 122 subcarriers in the first data pilot region as
The index of 122 subcarriers of 484-tone DRU 4 in the first data pilot region is
Wherein, the
For the second data pilot region:
In the case where any 484-tone DRU includes 120 subcarriers in the second data pilot region, the index can be expressed as:
484-tone DRU 1 index of 120 subcarriers in the second data pilot region as
484-Tone DRU 2 index of 120 subcarriers in the second data pilot region as
484-Tone DRU 3 index of 120 subcarriers in the second data pilot region as
484-Tone DRU 4 index of 120 subcarriers in the second data pilot region as

In other words, 242-tone DRU 1 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 2 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 3 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 4 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 5 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 6 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 7 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, 242-tone DRU 8 is distributed in the first data pilot region, the fourth data pilot region and the fourth data pilot region.
The 242-tone DRU 1-242-tone DRU 8 meets at least one of the following conditions:
The index difference of adjacent subcarriers distributed in the first data pilot region by any one 242-toneDRU of the 242-tone DRUs 1-242-tone DRUs 8 is 8, the index difference of adjacent subcarriers distributed in the second data pilot region by any one 242-tone DRU is 8, the index difference of adjacent subcarriers distributed in the third data pilot region by any one 242-tone DRU is 8, and the index difference of adjacent subcarriers distributed in the fourth data pilot region by any one 242-tone DRU is 8.
Or, for any 242-tone DRU of 242-tone DRU 1-242-tone DRU 8, the index difference of adjacent subcarriers distributed in each data pilot region is 8. For a description of adjacent subcarriers, reference is made to the above 1B, and details are not given here.
In the embodiment of the application, the 242-tone DRU can achieve larger power amplification factor, such as 8.13dB, by meeting the condition 1.
Condition 2:242-tone DRU 1, 242-tone DRU 2, 242-tone DRU 3, 242-tone DRU 4, a p-th subcarrier the p-th subcarrier in 242-tone DRU 5, the p-th subcarrier in 242-tone DRU 6, the p-th subcarrier in 242-tone DRU 7, the p-th subcarrier in 242-tone DRU 8, is continuous.
Illustratively, the p-th subcarrier in 242-tone DRU 1, the p-th subcarrier in 242-tone DRU 5, the p-th subcarrier in 242-tone DRU 3, the p-th subcarrier in 242-tone DRU 7, the p-th subcarrier in 242-tone DRU 2, the p-th subcarrier in 242-tone DRU 6, the p-th subcarrier in 242-tone DRU 4, and the p-th subcarrier in 242-tone DRU 8 are consecutive in order. Of course, the order shown here is merely an example, and as the number of 242-tone DRUs changes, the order shown here also changes, and the application is not limited in this regard.
Where p may be a positive integer less than or equal to 242.
In the embodiment of the application, the 242-tone DRU can ensure that eight 242-tone DRUs form an integral translation relationship by meeting the condition 2, thereby being beneficial to the storage of indexes and the simplification of sequence design.
Illustratively, the 242-tone DRU described above may also satisfy the following condition 3:
Any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the first data pilot region;
any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the second data pilot region;
any 242-tone DRU includes 60 subcarriers or 61 subcarriers in the third data pilot region;
any one 242-tone DRU includes 60 subcarriers or 61 subcarriers in the fourth data pilot region.
Since 60×2+61×2=242, it may include 60 subcarriers (or 61 subcarriers) in any two of the four data pilot regions described above for any one 242-tone DRU, which includes 61 subcarriers (or 60 subcarriers) in the remaining two data pilot regions. For example, the number of subcarriers belonging to different 242-tone DRUs in the same data pilot region may be the same for different 242-tone DRUs.
As one example 1, any one 242-tone DRU may include 60 subcarriers in the first and second data pilot regions, which include 61 subcarriers in the third and fourth data pilot regions.
As another example 2, any one 242-tone DRU may include 60 subcarriers in the first and third data pilot regions, and may include 61 subcarriers in the second and fourth data pilot regions.
As yet another example 3, any one 242-tone DRU may include 60 subcarriers in the first data pilot region and the fourth data pilot region, which may include 61 subcarriers in the second data pilot region and the third data pilot region.
As yet another example 4, any one 242-tone DRU may include 61 subcarriers in the first and second data pilot regions, which include 60 subcarriers in the third and fourth data pilot regions.
As yet another example 5, any one 242-tone DRU may include 61 subcarriers in the first and third data pilot regions, and 60 subcarriers in the second and fourth data pilot regions.
As yet another example 6, any one 242-tone DRU may include 61 subcarriers in the first data pilot region and the fourth data pilot region, which may include 60 subcarriers in the second data pilot region and the third data pilot region.
Illustratively, the 242-tone DRU described above may also satisfy the following condition 4:
For any 242-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 8, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of 8, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of 8.
In other words, for any 242-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region (i.e., 8), the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region.
For example, for any 242-tone DRU, the difference between its index of the last subcarrier in the first data pilot region and its index of the first subcarrier in the second data pilot region may be 8,16,24,32 or 40, etc., which are not listed here.
For any 242-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region are not limited as to whether the above differences are the same.
In the embodiment of the application, the 242-tone DRU can ensure that the PAPR of the 242-tone DRU is lower by meeting the condition 4.
Illustratively, the 242-tone DRU described above may also satisfy the following condition 5:
For either 242-tone DRU, 60 or 61 subcarriers in a first data pilot region may be shifted within the first data pilot region, or 60 or 61 subcarriers in a second data pilot region may be shifted within the second data pilot region, or 60 or 61 subcarriers in a third data pilot region may be shifted within the third data pilot region, or 60 or 61 subcarriers in a fourth data pilot region may be shifted within the fourth data pilot region.
The description of translation may also refer to the various index expressions shown below. For example, the 242-tone DRU may satisfy the above condition 5 when the above condition 1 to condition 4 are satisfied. In a specific implementation, in the case that the above condition 5 is satisfied, one index may be determined from a plurality of different indexes of the 4 242-tone DRUs. An index may be defined therefrom as an index of the 242-tone DRU, as a standard, or an index expression shown below may be defined, which is not limited by the present application.
In the embodiment of the application, under the condition that the conditions 1-4 are satisfied, the index of the 242-tone DRU can be designed in four data pilot frequency areas.
As one possible implementation, the first data pilot region has an index of [ -1012: -515], the second data pilot region has an index of [ -509: -12], the third data pilot region has an index of [12:509], and the fourth data pilot region has an index of [515:1012].
The index descriptions of the first protection region, the second dc region, the second protection region, the first dc region, and the third dc region may refer to the above implementation 1, and are not repeated here.
Under the four data pilot regions described above, 8 242-tone DRUs may be designed. As an example, under the four data pilot regions described above, 8 242-tone DRUs may be independently designed. As another example, under the four data pilot regions described above, 8 242-tone DRUs may be designed in conjunction with the 996-tone DRUs described above. As yet another example, under the four data pilot regions described above, 8 242-tone DRUs may be designed in conjunction with the 484-tone DRUs described above. The relationship of 242-tone DRUs, 484-tone DRUs, 996-tone DRUs may be referred to the description of fig. 4 and will not be described in detail herein. When designing a 242-tone DRU in combination with the 484-tone DRU or 996-tone DRU shown above, the index range of the 242-tone DRU cannot exceed the index range of the 484-tone DRU or the index range of the 996-tone DRU.

Wherein p may be a positive integer less than or equal to 106.
In the embodiment of the application, the 106-tone DRU can ensure that 16 242-tone DRUs form an integral translation relationship by meeting the condition 2, thereby being beneficial to the storage of indexes and the simplification of sequence design.
For example, the 106-tone DRU may also satisfy the following condition 3:
Any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the first data pilot region;
any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the second data pilot region;
any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the third data pilot region;
Any 106-tone DRU includes 26 subcarriers or 27 subcarriers in the fourth data pilot region.
For any one 106-tone DRU, it may include 26 subcarriers (or 27 subcarriers) in any two of the four data pilot regions described above, which includes 27 subcarriers (or 26 subcarriers) in the remaining two data pilot regions. For example, the number of subcarriers belonging to different 106-tone DRUs in the same data pilot region may be the same for different 106-tone DRUs.
As one example 1, any one 106-tone DRU may include 26 subcarriers in the first and second data pilot regions, which include 27 subcarriers in the third and fourth data pilot regions.
As another example 2, any one of the 106-tone DRUs may include 26 subcarriers in the first and third data pilot regions, and may include 27 subcarriers in the second and fourth data pilot regions.
As yet another example 3, any one of the 106-tone DRUs may include 26 subcarriers in the first data pilot region and the fourth data pilot region, and may include 27 subcarriers in the second data pilot region and the third data pilot region.
As yet another example 4, any one of the 106-tone DRUs may include 27 subcarriers in the first and second data pilot regions, which include 26 subcarriers in the third and fourth data pilot regions.
As yet another example 5, any one of the 106-tone DRUs may include 27 subcarriers in the first and third data pilot regions, and 26 subcarriers in the second and fourth data pilot regions.
As yet another example 6, any one of the 106-tone DRUs may include 27 subcarriers in the first data pilot region and the fourth data pilot region, which may include 26 subcarriers in the second data pilot region and the third data pilot region.
For example, the 106-tone DRU may also satisfy the following condition 4:
for any 106-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 16, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of 16, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of 16.
In other words, for any 106-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region (i.e., 16), the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of the difference between the index of its adjacent subcarriers in the same data pilot region.
For example, for any 106-tone DRU, the difference between its index of the last subcarrier in the first data pilot region and its index of the first subcarrier in the second data pilot region may be 16 or 32, etc., which are not listed here.
For any 106-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region are not limited as to whether the above differences are the same.
In the embodiment of the application, the 106-tone DRU can ensure that the PAPR of the 106-tone DRU is lower by meeting the condition 4.
For example, the 106-tone DRU may also satisfy the following condition 5:
For any 106-tone DRU, 26 or 27 subcarriers in a first data pilot region may be shifted within the first data pilot region, or 26 or 27 subcarriers in a second data pilot region may be shifted within the second data pilot region, or 26 or 27 subcarriers in a third data pilot region may be shifted within the third data pilot region, or 26 or 27 subcarriers in a fourth data pilot region may be shifted within the fourth data pilot region.
The description of translation may also refer to the various index expressions shown below. For example, the 106-tone DRU may satisfy the above condition 5 when the above condition 1 to condition 4 are satisfied. In a specific implementation, the 106-tone DRU may determine one index from a plurality of different indexes of the 4 106-tone DRUs if the above condition 5 is satisfied. An index may be defined therefrom as an index of the 106-tone DRU, as a standard, or an index expression shown below may be defined, which is not limited by the present application.
In the embodiment of the application, under the condition that the conditions 1-4 are satisfied, the index of the 106-tone DRU can be designed in four data pilot frequency areas.
As one possible implementation, the first data pilot region has an index of [ -1012: -515], the second data pilot region has an index of [ -509: -12], the third data pilot region has an index of [12:509], and the fourth data pilot region has an index of [515:1012].
The index descriptions of the first protection region, the second dc region, the second protection region, the first dc region, and the third dc region may refer to the above implementation 1, and are not repeated here.
Under the four data pilot regions described above, 16 106-tone DRUs can be designed. As an example, under the four data pilot regions described above, 16 106-tone DRUs may be independently designed. As another example, under the four data pilot regions described above, 16 106-tone DRUs may be designed in conjunction with the 996-tone DRUs described above. As yet another example, under the four data pilot regions described above, 8 106-tone DRUs may be designed in conjunction with the 484-tone DRUs described above. As yet another example, under the four data pilot regions described above, 16 106-tone DRUs may be designed in conjunction with the 242-tone DRUs described above. The relationship of the 106-tone DRUs, 242-tone DRUs, 484-tone DRUs, 996-tone DRUs may be referred to the description of fig. 4 and will not be described in detail herein. When designing a 106-tone DRU in combination with a 242-tone DRU, 484-tone DRU or 996-tone DRU as shown above, the index range of the 106-tone DRU cannot exceed the index range of the 242-tone DRU, 484-tone DRU or 996-tone DRU.

2A、996-tone DRU
996-Tone DRU 1 satisfies the following conditions:
996-tone DRU 1 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, and 996-tone DRU 1 includes odd-numbered subcarriers in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region.
996-Tone DRU 2 satisfies the following conditions:
996-tone DRU 2 is distributed in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region, and 996-tone DRU 2 includes even-numbered subcarriers in the first data pilot region, the second data pilot region, the third data pilot region and the fourth data pilot region.
As an example, the first to fourth data pilot regions may not include null subcarriers. The total number of subcarriers in these four data pilot regions is 996×2=1992. As another example, the first to fourth data pilot regions may include null subcarriers therein. The total number of remaining subcarriers except for null subcarriers in the four data pilot regions may be 1992, for example. For a description of the region, reference is also made to the above 1A, which is not described in detail here.
996-Tone DRU 1 may satisfy the following conditions:
996-tone DRU 1 has an index of the last subcarrier in the first data pilot region and an index of the first subcarrier in the second data pilot region that differ by an integer multiple of 2, has an index of the last subcarrier in the second data pilot region and an index of the first subcarrier in the third data pilot region that differ by an integer multiple of 2, and has an index of the last subcarrier in the third data pilot region and an index of the first subcarrier in the fourth data pilot region that differ by an integer multiple of 2.
996-Tone DRU 2 may satisfy the following relationship:
996-tone DRU 2 has an index of the last subcarrier in the first data pilot region and an index of the first subcarrier in the second data pilot region that differ by an integer multiple of 2, has an index of the last subcarrier in the second data pilot region and an index of the first subcarrier in the third data pilot region that differ by an integer multiple of 2, and has an index of the last subcarrier in the third data pilot region and an index of the first subcarrier in the fourth data pilot region that differ by an integer multiple of 2.
The descriptions of 996-tone DRU 1 and 996-tone DRU 2 are also referred to above in connection with 1A and will not be described in detail here.
In the embodiment of the application, the 996-tone DRU 1 or the 996-tone DRU 2 can ensure that the peak average power ratio (peak to average power ratio, PAPR) of the 996-tone DRU is lower by meeting the conditions in the data pilot frequency region.
Under the condition that the condition is met, the index of 996-tone DRU can be designed in four data pilot frequency areas, so that the power amplification factor can be improved, and the PAPR can be ensured to be lower.
In one possible implementation, the first data pilot region has an index of [ -1012: -515], the second data pilot region has an index of [ -509: -12], the third data pilot region has an index of [12:509], and the fourth data pilot region has an index of [515:1012].
Since the index of the first subcarrier in the first data pilot region is even, the index of the first subcarrier in the second data pilot region is odd, the index of the first subcarrier in the third data pilot region is even, and the index of the first subcarrier in the fourth data pilot region is odd, the 996-tone DRU 1 above includes the first data pilot region, the second data pilot region, the third data pilot region, and the odd-numbered subcarrier in the fourth data pilot region, and may be replaced with 996-tone DRU 1 including the even-numbered subcarrier in the first data pilot region, the odd-numbered subcarrier in the second data pilot region, the even-numbered subcarrier in the third data pilot region, and the odd-numbered subcarrier in the fourth data pilot region. Similarly, 996-tone DRU 2 comprises a first data pilot region, a second data pilot region, a third data pilot region and an even number of subcarriers in a fourth data pilot region, and 996-tone DRU 1 can be replaced by a method that comprises the steps of enabling subcarriers with odd indexes in the first data pilot region, enabling subcarriers with even indexes in the second data pilot region, enabling subcarriers with odd indexes in the third data pilot region and enabling subcarriers with even indexes in the fourth data pilot region.
The description of the respective areas is also referred to the above implementation 1, and will not be described in detail here.
The index of the 996-tone DRU is as follows:
the subcarrier index of 996-tone DRU 1 is [ -1012:2: -516, -509:2: -13,12:2:508,515:2:1011];
The subcarrier index of 996-tone DRU 2 is [ -1011:2: -515, -508:2: -12,13:2:509,516:2:1012].
In the embodiment of the application, 996-tone DRU 1 or 996-tone DRU 2 is uniformly distributed in four data pilot frequency areas, which is more beneficial to channel smoothing and can ensure low PAPR.
2B、484-tone DRU
484-Tone DRU 1, 484-tone DRU 2, 484-tone DRU 3, 484-tone DRU 4 are all distributed over the first data pilot region, the second data pilot region, the third data pilot region, and the fourth data pilot region.

The index difference of the adjacent subcarriers of 484-tone DRU 1-484-tone DRU 4, of which any one 484-toneDRU is distributed in the first data pilot region, the index difference of the adjacent subcarriers of any one 484-tone DRU is 4, the index difference of the adjacent subcarriers of any one 484-tone DRU is distributed in the second data pilot region, the index difference of the adjacent subcarriers of any one 484-tone DRU is 4, and the index difference of the adjacent subcarriers of any one 484-tone DRU is distributed in the fourth data pilot region, is 4;
the p-th subcarrier in 484-tone DRU1, the p-th subcarrier in 484-tone DRU 2, the p-th subcarrier in 484-tone DRU 3, and the p-th subcarrier in 484-tone DRU 4 are consecutive.
Regarding the index difference of adjacent subcarriers, and the successive description can be referred to the condition 1 and the condition 2 in the above 1B, which will not be described in detail here.
Illustratively, a 484-tone DRU may also satisfy:
any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the first data pilot region;
any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the second data pilot region;

Any 484-tone DRU includes 120 subcarriers or 122 subcarriers in the fourth data pilot region.
The description of 120 subcarriers or 122 subcarriers may also refer to condition 3 in the above 1B, and examples 1 to 6 as shown above are equally applicable to 2B, and will not be described in detail here.
Illustratively, a 484-tone DRU may also satisfy the following conditions:
For any one 484-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 4, the difference between the index of its last subcarrier in the second data pilot region and the index of its first subcarrier in the third data pilot region is an integer multiple of 4, and the difference between the index of its last subcarrier in the third data pilot region and the index of its first subcarrier in the fourth data pilot region is an integer multiple of 4.
For the description of the index difference, reference is also made to condition 4 in the above 1B, and details thereof will not be given here.
Illustratively, a 484-tone DRU may also satisfy the following conditions:
for either 484-tone DRU, 120 or 122 subcarriers in the first data pilot region may be shifted within the first data pilot region, or 120 or 122 subcarriers in the second data pilot region may be shifted within the second data pilot region, or 120 or 122 subcarriers in the third data pilot region may be shifted within the third data pilot region, or 120 or 122 subcarriers in the fourth data pilot region may be shifted within the fourth data pilot region.
For a description of translation, reference is also made to condition 5 in 1B above, which is not described in detail here.
In one possible implementation, the first data pilot region has an index of [ -1012: -515], the second data pilot region has an index of [ -509: -12], the third data pilot region has an index of [12:509], and the fourth data pilot region has an index of [515:1012].
For the design of the four data pilot regions, 484-tone DRUs, reference is made to the description of 1B above, which is not described in detail herein.
In the embodiment of the present application, in the case of independently designing 484-tone DRUs in the four data pilot regions, since the index ranges of the corresponding data pilot regions listed in the second subcarrier planning and the first subcarrier planning are the same, 484-tone DRUs in the second subcarrier planning and 484-tone DRUs in the first subcarrier planning may be regarded as the same. However, when the 484-tone DUR under the second sub-carrier plan is a combined 996-tone DRU design, the 484-tone DRU under the second sub-carrier plan is different from the 484-tone DRU under the first sub-carrier plan in index.
A number of possibilities for indexing the individual 484-tone DRUs are presented below.
For a first data pilot region:
In one possible implementation, where any one 484-tone DRU includes 120 subcarriers in the first data pilot region, the index may be expressed as:

For the design of the four data pilot regions, 242-tone DRUs, reference is made to the description of 1D above, which is not described in detail herein.
In the embodiment of the present application, under the condition that the 106-tone DRUs are independently designed under the four data pilot frequency regions, the 106-tone DRUs under the second subcarrier planning and the 106-tone DRUs under the first subcarrier planning can be considered to be the same because the index ranges of the corresponding data pilot frequency regions listed in the second subcarrier planning and the first subcarrier planning are the same. But when the 106-tone DUR under the second subcarrier plan is designed in combination with the 996-tone DRU, or in combination with the 484-tone DRU, or in combination with the 242-tone DRU, the index of the 106-tone DRU under the second subcarrier plan is different from the index of the 106-tone DRU under the first subcarrier plan.

For example, the subcarriers in the first protection region and the second protection region may be protection subcarriers. In general, the subcarriers in the direct current region may be direct current subcarriers, but the present application is not limited thereto. The first data pilot region and the second data pilot region may include data subcarriers and pilot subcarriers. Alternatively, the first data pilot region may include null subcarriers. Alternatively, the second data pilot region may include null subcarriers. The names of the above-described respective areas are merely examples, and the present application is not limited thereto.
The first data pilot region is located between the first protection region and the direct current region, and the second data pilot region is located between the direct current region and the second protection region. Fig. 5b is another schematic diagram of region division according to an embodiment of the present application. Fig. 5b schematically shows the frequency domain positions of the above-mentioned respective areas.
The embodiment of the application designs DRU with different sizes in the first data pilot frequency area and the second data pilot frequency area. For example, in the two data pilot frequency areas, 2 996-tone DRUs (for example, 996-tone DRU 1 and 996-tone DRU 2), 4 484-tone DRUs (for example, 484-tone DRU 1, 484-tone DRU 2, 484-tone DRU 3 and 484-tone DRU 4), 8 242-tone DRUs (for example, 242-tone DRU 1 to 242-tone DRU 8) and 16 106-tone DRUs (for example, 106-tone DRU 1 to 106-tone DRU 16) are respectively designed in the embodiment of the present application. The DRUs of different sizes may be a single embodiment, or the DRUs of different sizes may be combined into one embodiment, which is not limited by the present application. The following detailed description:
3A、996-tone DRU
996-tone DRU 1 is distributed in the first data pilot region and the second data pilot region. 996-tone DRU 2 is distributed in the first data pilot region and the second data pilot region.
996-Tone DRU 1 or 996-tone DRU 2 may satisfy at least one of the following conditions:
The index difference of adjacent subcarriers of which 996-tone DRU 1 or 996-tone DRU 2 is distributed in the first data pilot region is 2,996-tone DRU 1 or 996-tone DRU 2 and the index difference of adjacent subcarriers of which is distributed in the second data pilot region is 2.
Alternatively, for 996-tone DRU 1 or 996-tone DRU, the index difference of adjacent subcarriers distributed in each data pilot region is 2. For the description of the adjacent subcarriers, reference may be made to the description in the first subcarrier planning above, and no further description is given here.
In the embodiment of the application, the 996-tone DRU can achieve larger power amplification factor by meeting the condition 1.
The p-th subcarrier in the 996-tone DRU 1 and the p-th subcarrier in the 996-tone DRU 2 are consecutive.
P may be a positive integer less than or equal to 996.
In the embodiment of the application, the 996-tone DRU can ensure that two 996-tone DRUs form an integral translation relationship by meeting the condition 2, thereby being beneficial to the storage of indexes and the simplification of sequence design.
Illustratively, the 996-tone DRU described above may also satisfy the following condition 3:
Condition 3:996-tone DRU 1 or 996-tone DRU 2 includes 498 subcarriers in the first data pilot region, 996-tone DRU 1 or 996-tone DRU 2 includes 498 subcarriers in the second data pilot region.
That is, either 996-tone DRU 1 or 996-tone DRU 2 may be uniformly distributed over the first data pilot region and the second data pilot region.
In the embodiment of the present application, the 996-tone DRU can be uniformly distributed in the two data pilot areas by including the sub-carriers in the 498 996-tone DRU 1 and the sub-carriers in the 498 996-tone DRU 2 in the first data pilot area, and by including the sub-carriers in the 498 996-tone DRU 1 and the sub-carriers in the 498 996-tone DRU 2 in the second data pilot area. Therefore, when 484-tone DRUs or 242-tone DRUs or 106-tone DRUs are designed based on 996-tone DRUs, DRUs with different sizes can form an integral translation relation, and the storage and the reading of indexes are facilitated.
Exemplary, 996-tone DRU may also satisfy the following condition 4:
For either 996-tone DRU 1 or 996-tone DRU 2, the difference between the index of its last subcarrier in the first data pilot region and its index of its first subcarrier in the second data pilot region is an integer multiple of 2.
Alternatively stated, for either 996-tone DRU 1 or 996-tone DRU 2, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of the difference between the indices of its adjacent subcarriers in the first data pilot region (or the second data pilot region).
In the embodiment of the application, the 996-tone DRU can ensure that the PAPR of the 996-tone DRU is lower by meeting the condition 4.
Under the condition that the condition is met, the index of 996-tone DRU can be designed in four data pilot frequency areas, so that the power amplification factor can be improved, and the PAPR can be ensured to be lower.
Exemplary, 996-tone DRU may also satisfy the following condition 5:
For either 996-tone DRU, its 498 subcarriers in the first data pilot region may be shifted within the first data pilot region, or its 498 subcarriers in the second data pilot region may be shifted within the second data pilot region.
The description of translation may also refer to the various index expressions shown below. For example, the 996-tone DRU may satisfy the above condition 5 in the case of satisfying the above conditions 1 to 4. In a specific implementation, in the case that the 996-tone DRU satisfies the above condition 5, one index may be determined from a plurality of different indexes of 2 996-tone DRUs. An index may be defined as an index of the 996-tone DRU as a standard, or an index expression shown below may be defined, which is not limited by the embodiment of the present application.
Under the condition that the condition is met, the index of 996-tone DRU can be designed in two data pilot frequency areas in subcarrier planning, so that the power amplification factor can be improved, and the PAPR can be ensured to be lower.
As one possible implementation 2, the index of the first data pilot region is [ -1012: -12], and the index of the second data pilot region is [12:1012].
Illustratively, the first protection region may have an index of [ -1024:1013 ], the DC region may have an index of [ -11:11], and the second protection region may have an index of [1013:1023]. That is, according to the frequency from low to high, the 1 st to 12 th subcarriers among 2048 subcarriers are guard subcarriers, the 1014 th to 1036 th subcarriers are direct current subcarriers (or called guard subcarriers), and the 2038 th to 2048 th subcarriers are guard subcarriers.
Of course, the index ranges of the respective areas listed in the above implementation 2 are merely examples, and, in a specific implementation, the index range of at least one area of the first protection area, the second protection area, or the dc area may be smaller, which is not limited by the embodiment of the present application. In case that an index range of at least one of the first guard region, the second guard region, or the direct current region is smaller, the index range of the first data pilot region or the second data pilot region may be larger, and at this time, null subcarriers may be included in the two data pilot regions.
The following describes a number of possibilities for indexing a 996-tone DRU with the index range listed in implementation 2 as an example.
For a first data pilot region:
The index of 498 subcarriers of 996-tone DRU1 in the first data pilot region is [ -1012:2: -18] +t 1,
The index of 498 subcarriers of 996-tone DRU 2 in the first data pilot region is [ -1011:2: -17] +t 1,
Where t 1 = 0,2 or 4.
For the second data pilot region:
996-tone DRU1 indexes 498 subcarriers in the second data pilot region as [12:2:1006] +t 2,
996-Tone DRU 2 has an index of 498 subcarriers in the second data pilot region of [13:2:1007] +t 2,
Where t 2 = 0,2 or 4.
In the embodiment of the present application, t 1 may be referred to as a shift value, and the superscript may be used to distinguish between different data pilot regions. For the translation values, reference may be made to the description in 1B above, and no further description is given here.
The index of the 996-tone DRU is described below.
The index of 996-tone DRU 1 is [ -1008:2: -14,12:2:1006], and the index of 996-tone DRU 2 is [ -1007:2: -13:2:1007 ].

For any 484-tone DRU, the difference between the index of its last subcarrier in the first data pilot region and the index of its first subcarrier in the second data pilot region is an integer multiple of 4. Alternatively stated, for any one 484-tone DRU, the difference between its index of the last subcarrier in the first data pilot region and its index of the first subcarrier in the second data pilot region is an integer multiple of its index difference of adjacent subcarriers in the first data pilot region (or the second data pilot region);

In the application, for the first and second subcarrier planning, each DRU can reach the maximum power amplification factor, and each DRU is uniformly distributed in four data pilot frequency areas, so that the channel smoothing is facilitated. Meanwhile, for any DRU, the difference between the index of the last subcarrier in the previous data pilot region and the index of the first subcarrier in the next data pilot region is an integer multiple of the index difference of the adjacent subcarriers in one data pilot region, thereby ensuring low PAPR. The DRUs with the same size can conform to the integral translation relation, so that two local oscillators (localoscillator, LO) can be allowed to realize 160MHz by reserving a direct current region, and the realization difficulty of the radio frequency front end can be reduced.
In the application, for the third subcarrier planning and the fourth subcarrier planning, the whole bandwidth is divided into two data pilot frequency areas, which is more beneficial to channel smoothing and reducing PAPR of DRU.

And transceivers are used to communicate with other devices/means via transmission media.
Optionally, the communication device 70 may also include one or more memories 730 for storing program instructions and/or data. Memory 730 is coupled to processor 720. The coupling in the embodiments of the present application is an indirect coupling or communication connection between communication devices, units or modules, which may be in electrical, mechanical or other forms for information interaction between the communication devices, units or modules. Processor 720 may operate in conjunction with memory 730. Processor 720 may execute program instructions stored in memory 730. In the alternative, at least one of the one or more memories may be included in the processor.
The specific connection medium between the transceiver 710, the processor 720, and the memory 730 is not limited in the embodiment of the present application. In the embodiment of the present application, the memory 730, the processor 720 and the transceiver 710 are connected through the bus 740 in fig. 7, and the bus is shown by a thick line in fig. 7, and the connection manner between other components is only schematically illustrated, but not limited thereto. The buses may be classified as address buses, data buses, control buses, etc. For ease of illustration, only one thick line is shown in fig. 7, but not only one bus or one type of bus.
In the embodiment of the present application, the processor may be a general purpose processor, a digital signal processor, an application specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, or the like, and may implement or execute the methods, steps, and logic blocks disclosed in the embodiment of the present application. The general purpose processor may be a microprocessor or any conventional processor or the like. The steps of the method disclosed in connection with the embodiments of the present application may be embodied directly in a hardware processor for execution, or in a combination of hardware and software modules in the processor for execution, etc.
In an embodiment of the present application, the Memory may include, but is not limited to, nonvolatile Memory such as a hard disk (HARD DISK DRIVE, HDD) or Solid State Disk (SSD), random access Memory (Random Access Memory, RAM), erasable programmable Read-Only Memory (Erasable Programmable ROM, EPROM), read-Only Memory (ROM), or portable Read-Only Memory (Compact Disc Read-Only Memory, CD-ROM), etc. The memory is any storage medium that can be used to carry or store program code in the form of instructions or data structures and that can be read and/or written by a computer (e.g., a communication device, etc., as illustrated by the present application), but is not limited thereto. The memory in embodiments of the present application may also be circuitry or any other device capable of performing memory functions for storing program instructions and/or data.
The processor 720 is mainly used for processing communication protocols and communication data, controlling the whole communication device, executing software programs and processing data of the software programs. Memory 730 is primarily used to store software programs and data. The transceiver 710 may include control circuitry for primarily converting baseband signals to radio frequency signals and processing the radio frequency signals, and an antenna. The antenna is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used for receiving data input by a user and outputting data to the user.
When the communication device is powered on, the processor 720 may read the software program in the memory 730, interpret and execute instructions of the software program, and process data of the software program. When data is required to be transmitted wirelessly, the processor 720 performs baseband processing on the data to be transmitted, and then outputs a baseband signal to the radio frequency circuit, and the radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal outwards in the form of electromagnetic waves through the antenna. When data is transmitted to the communication device, the radio frequency circuit receives a radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 720, and the processor 720 converts the baseband signal into data and processes the data.
In another implementation, the radio frequency circuitry and antenna may be provided separately from the processor performing the baseband processing, e.g., in a distributed scenario, the radio frequency circuitry and antenna may be in a remote arrangement from the communication device.
The communication device shown in the embodiment of the present application may also have more components and the like than those shown in fig. 7, which is not limited thereto.
