In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1, FIG. 1 is a schematic diagram of a network structure applicable to an embodiment of the present invention. As shown in FIG. 1, it includes a terminal 11 and a network side device 12, wherein the terminal 11 may be a user terminal (User Equipment, UE) or Other terminal devices, such as mobile phones, tablet computers (Tablet Personal Computer), laptop computers (Laptop Computer), personal digital assistants (PDAs), mobile Internet devices (MID) or wearables It should be noted that, in the embodiment of the present invention, the specific type of the terminal is not limited in the terminal device such as a wearable device (Wearable Device).

It should be noted that the specific types of network-side devices are not limited in the embodiments of the present invention.

Please refer to FIG. 2. FIG. 2 is a flowchart of an energy-saving signal transmission method according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps: 201. A network-side device determines transmission resources of an energy-saving signal; 202. The network The roadside device sends the energy-saving signal through the transmission resource, where the energy-saving signal includes multiple sequences.

In the embodiment of the present invention, the above energy-saving signal may be used for a wake-up signal, or for starting (or called triggering) the detection control channel, or for enabling the terminal to start the detection related to the decoding of the control channel. For example, the energy-saving signal may be a wake-up signal (Wakeup Signal, WUS). Of course, this is not limited. For example, the energy-saving signal may also be other signals defined in an agreement, or other signals previously agreed between the network-side device and the terminal.

The transmission resource of the energy-saving signal may refer to a transmission resource used to transmit the energy-saving signal. The above-mentioned determination of the energy-saving signal transmission resource may be determined according to the terminal or the terminal group, for example: the energy-saving signal transmission resource of each terminal may be determined separately for each terminal, or the energy-saving signal transmission resource of the terminal in the terminal group may be determined according to the terminal group .

In addition, in the embodiment of the present invention, the same sequence indicator may indicate one or more functions, for example, a certain sequence may indicate a wake up area ID (Wake up area ID), a cell ID (Cell ID), a terminal ID, carrier information, One or more of system information update, distance information, data end, etc. Since the energy-saving signal includes multiple sequences, the energy-saving signal can indicate multiple functions to the terminal, and after receiving the energy-saving signal, the terminal can parse the instructions of these functions and then perform the corresponding actions. For example: wake up, detect control channel, detect data channel, obtain system information and go to sleep, etc. In this way, multiple functions can be indicated through the above multiple sequences, so that the communication performance of the communication system can be improved.

In addition, in the embodiment of the present invention, the above energy-saving signal may be applied to a connected (RRC_Connected) terminal, or a non-connected terminal, such as an idle state (RRC_IDLE) terminal or an inactive state (RRC_Inactive) terminal. And in some embodiments, the same energy-saving signal can be applied to both the connected terminal and the non-connected terminal, so that the energy-saving signal has a nested feature, thereby saving transmission resources.

It should be noted that, in the embodiment of the present invention, the control channel may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH), but this is not limited. In the embodiment of the present invention, the control channel may refer to the existing and future Various possible definition control channels, for example: enhanced physical downlink control channel (Enhanced Physical Downlink Control Channel, ePDCCH) or machine type communication entity downlink control channel (MTC Physical Downlink Control Channel, MPDCCH), etc. In addition, the embodiments of the present invention may support licensed frequency bands or unlicensed frequency bands. The embodiments of the present invention can be applied to NR technology or other communication systems, such as LTE.

Optionally, in the embodiment of the present invention, the energy saving signal includes three or more sequences. In this way, three or more sequences can enable the energy-saving signal to realize more functions, thereby further improving the communication performance of the communication system. Of course, in the embodiment of the present invention, the energy-saving signal may also include two sequences, which is not limited.

As an optional implementation manner, the network-side device determining the transmission resource of the energy-saving signal includes: the network-side device grouping the terminals that need to monitor the energy-saving signal, and determining the transmission resource of the energy-saving signal for each terminal group.

Among them, grouping the terminals may be grouping according to the terminal identifier (UE ID) of the terminals, for example: terminals in the same terminal group have the same UE ID, or terminals in the same terminal group have different UE IDs but satisfy certain Relationship, for example, the UE ID of the terminal in the same terminal group is the same after taking a certain modulus. In addition, the UE ID in the embodiment of the present invention may be a user identity, and is not limited to the radio network temporary identity (RNTI), for example, it may be that the terminal is in a wake up area (Wake up area) or paging The ID information in the paging area may also be a function of the terminal's globally unique identification, such as the terminal's globally unique identification modulo operation.

In this embodiment, since the transmission resource of the energy-saving signal is determined according to the terminal group, it can effectively prevent the network side device from sending the wake-up signals of all terminals on the same resource, thereby reducing the interference of the terminal detecting the wake-up signal, and also Reduce the difficulty of wake-up signal design.

Optionally, the energy-saving signal includes one or more signal subsets; wherein at least one signal subset of terminals in the same terminal group uses the same transmission resources, and the transmission resources include time-domain resources and frequency-domain resources; or the same At least one signal subset of the terminals in the terminal group uses different transmission resources, and the transmission resources include time domain resources and frequency domain resources; or at least one signal subset of the terminals in the same terminal group uses the same time domain resources, and At least one signal subset of different terminals in the same terminal group uses different frequency domain resources; or at least one signal subset of terminals in the same terminal group uses the same frequency domain resources, and at least one signal of different terminals in the same terminal group The subset uses different time domain resources.

In the embodiment of the present invention, the signal subset may be one or more symbols, and the same signal subset may include one or more sequences. In addition, it should be noted that the one or more signal subsets may be referred to as one or more subsets of one energy-saving signal, and of course, one or more different energy-saving signals. In addition, transmission resources of different signal subsets may be different, for example, different signal subsets are sent in different time-domain resources.

The use of the same transmission resource for at least one signal subset of terminals in the same terminal group may mean that all signal subsets of terminals in the same terminal group use the same time-domain resource and frequency-domain resource; or, in the same terminal group Part of the signal subset of the terminal uses the same time domain resource and frequency domain resource, while another part of the signal subset uses the same time domain resource, but uses a different frequency domain resource, or another part of the signal subset uses the same frequency domain Resources, but using different time-domain resources. That is to say, multiple resource configuration methods can be used in combination. For example, when the energy-saving signal includes multiple signal subsets to be transmitted, each signal subset can be considered to map different resource configuration schemes.

In this embodiment, since at least one signal subset of terminals in the same terminal group uses the same time-domain resource and frequency-domain resource, transmission resources for transmitting energy-saving signals in the communication system can be saved.

The use of different transmission resources for at least one signal subset of terminals in the same terminal group may be that all or part of the signal subsets of terminals in the same terminal group use different time-domain resources and frequency-domain resources.

In this embodiment, since at least one signal subset of terminals in the same terminal group uses different transmission resources, it can be flexibly configured according to the needs of different terminals, thereby improving the flexibility of energy-saving signal transmission and increasing the communication system Communication performance.

At least one signal subset of the terminals in the same terminal group uses the same time-domain resources, and at least one signal subset of different terminals in the same terminal group uses different frequency-domain resources may mean that all signal sub-groups in the same terminal group The set uses the same time-domain resources, different signal subsets use different frequency-domain resources, or it can mean that some signal subsets in the same terminal group use the same time-domain resources, and different signal subsets in this part of the signal subset use different Frequency resources. In this way, different energy-saving signals can be sent to multiple terminals in the same time-domain resource, so that the time-domain resources of the terminal can be saved.

At least one signal subset of the terminals in the same terminal group uses the same frequency domain resource, and at least one signal subset of different terminals in the same terminal group uses different time domain resources. This may refer to all signal subgroups in the same terminal group The set uses the same frequency domain resources, different signal subsets use different time domain resources, or it can mean that some signal subsets in the same terminal group use the same frequency domain resources, and different signal subsets in this part of the signal subset use different Time-domain resources. In this way, different energy-saving signals can be sent to multiple terminals in the same frequency domain resource, thereby saving the terminal's frequency domain resources.

It should be noted that, in the embodiment of the present invention, the unit of time domain resources may refer to different Orthogonal Frequency Division Multiplexing (OFDM) symbols or time slots or other time domain resource units. limited. The unit of the frequency domain resource may be a physical resource block (PRB), or may be a subcarrier or a frequency domain resource unit, which is not limited.

As an optional embodiment, the network-side device determining the energy-saving signal transmission resource includes: the network-side device is a terminal or a terminal group, and determining the frequency-domain resource of the energy-saving signal corresponding to the terminal identification; and/or the network The roadside device determines the time-domain resource of the energy-saving signal of the terminal according to the terminal identifier.

Among them, the terminals in the above terminal group have the same UE ID, or the UE IDs of the terminals in the terminal group are different but satisfy a certain relationship, for example, the UE IDs of the terminals in the same terminal group in the group are the same after modulo a certain value .

The frequency domain resource of the energy-saving signal corresponding to the terminal identification may be that the frequency domain resource determined for the terminal corresponds to the terminal identification of the terminal, or the frequency domain resource determined for the terminal group and the terminal identification in the terminal group Corresponding.

Since the determined frequency domain resources and time domain resources correspond to the terminal identification, it can be achieved that no additional information needs to be added when determining the frequency domain resources and time domain resources, so as to reduce the complexity of implementation.

Optionally, the network-side device is a terminal or terminal group, and determining the frequency domain resource of the energy-saving signal corresponding to the terminal identification includes: the network-side device determines the terminal identification for the terminal or terminal group in a static or semi-static manner The frequency-domain resource of the corresponding energy-saving signal; and/or the network-side device determines the time-domain resource of the energy-saving signal of the terminal according to the terminal identification, including: the network-side device according to the terminal identification and discontinuous reception (Discontinuous Reception, DRX) The period determines the time-domain resource of the energy-saving signal of the terminal.

Wherein, the above network side device determines the frequency domain resource of the energy saving signal corresponding to the terminal identifier for the terminal or terminal group in a static or semi-static manner, which may include: the network side device passes Radio Resource Control (RRC) Signaling semi-statically, for the terminal or terminal group to determine the frequency domain resource of the energy-saving signal corresponding to the terminal identification; or the network-side device determines the terminal or terminal group corresponding to the terminal identification by way of pre-agreed or system information indication Frequency-domain resources of energy-saving signals.

In this embodiment, since the frequency domain resource of the energy-saving signal corresponding to the terminal identification is determined for the terminal or the terminal group in a static or semi-static manner, transmission resources of dynamic signaling can be reduced to save transmission resources.

As an optional implementation manner, the energy-saving signal includes multiple signal subsets, where some signal subsets are located before other signal subsets.

The time domain resources of the other signal subsets may be dynamically configured, for example, the energy-saving signal includes signal subset 1 and signal subset 2, where signal subset 1 is in front of signal subset 2 and signal subset 2 The time domain resource of is related to the real sending start point of the data, for example, the interval between the time domain resource of signal subset 2 and the real sending start point of the data is 0, or the interval is within a preset range, and so on. However, the time domain resources of the above partial signal subsets may be statically or semi-statically configured.

It should be noted that this embodiment is not limited to DRX scenarios. For example, in a non-DRX scenario, the above energy-saving signals may also include multiple signal subsets, where some signal subsets are located in other signal subsets. prior to.

Wherein, for the DRX scenario, the time domain resources of the above partial signal subset may be based on the terminal identifier and the DRX cycle. In the case where the energy-saving signal includes multiple signal subsets, the network-side device determines the time-domain resource of the terminal's energy-saving signal according to the terminal identification and the DRX cycle, which may include: the network-side device determines the terminal's energy-saving according to the terminal identification The time domain resources of some signal subsets of the signal are before the DRX cycle or within the DRX cycle, where the other signal subsets are dynamically transmitted on the OFDM symbol.

In this embodiment, it can be determined that the time domain resources of some signal subsets are before the DRX cycle or within the DRX cycle, while the other signal subsets are dynamically transmitted, which can improve the flexibility of energy-saving signal transmission and can also reduce the function of the terminal . For example, a subset of signals can be dynamically transmitted in the OFDM symbol before the PDCCH, so that the terminal can reduce the time for the terminal to blindly detect the PDCCH to achieve the purpose of energy saving function.

Of course, in the embodiment of the present invention, the network-side device determining the time-domain resource of the energy-saving signal of the terminal according to the terminal identifier and the DRX cycle may also be determining the time of all signal subsets of the energy-saving signal of the terminal according to the terminal identifier and the DRX cycle The domain resources are all before the DRX cycle or within the DRX cycle and other methods, which are not limited. For example, for non-DRX scenarios, the time domain resources corresponding to the terminal identifier may also be determined.

In addition, in the embodiment of the present invention, determining the time-domain resource of the energy-saving signal of the terminal according to the terminal identification may also be determined according to the terminal identification through a pre-agreed algorithm, or according to the semi-static configuration of the terminal identification, etc. limited. In addition, some parameters in the above algorithm may be semi-statically configured.

Optionally, the time domain resource of the partial signal subset is determined by a pre-agreed algorithm; and/or the time domain resource of the partial signal subset is semi-statically configured by the network side device.

Wherein, the above and/or indicates that the time domain resources of some signal subsets can be configured through pre-agreed algorithms and/or semi-statically. For example, the above algorithm may include semi-statically configured parameters such as the DRX cycle can be semi-statically configured.

Among them, the above algorithm may be pre-agreed by the network-side device and the terminal, or pre-defined in the protocol, so that the time-domain resources are determined by the pre-agreed algorithm, thereby reducing the previous transmission overhead of the network-side device and the terminal. In addition, The time domain resource is determined through the above algorithm, so that the time domain resource configuration can be made more flexible.

For example: if the time domain resource of the partial signal subset is determined by the algorithm, the location of the time domain resource of the partial signal subset is a function of the terminal identification and the DRX cycle; and/or if the time of the partial signal subset The domain resources are semi-statically configured by the network-side device, and the time domain resources of the subset of signals are notified by RRC signaling dedicated to the terminal.

Among them, the above function may be pre-agreed by the network side device and the terminal, or pre-defined in the protocol, and the specific content of the function is not limited, for example: the above function may include operations such as addition, subtraction, multiplication, division, or modulo .

In addition, the semi-static configuration is not limited to notification through terminal-specific RRC signaling, but may also be through other high-level signaling or system information indication, etc., which is not limited.

As an optional embodiment, for the unlicensed frequency band, the frequency domain resource of the energy-saving signal of one or more terminals is an interlace structure occupying the full bandwidth; and/or for the licensed frequency band, the frequency band of one or more terminals The frequency domain resource of the energy-saving signal is an interlace structure occupying part or all of the bandwidth.

The above-mentioned unlicensed frequency band may include an unlicensed frequency band, and of course, it may also refer to an unlicensed frequency band other than the unlicensed frequency band. The above interlace structure occupying the full bandwidth may be an interlace structure occupying the entire transmission bandwidth of the terminal.

Optionally, the interlace structure includes multiple resource sets, and resources with the same index in the multiple resource sets serve as an interlace; that is, the interlace structure may include multiple interlaces, where each interlace includes a different resource set In the same indexed resource.

For example: the resource set is a group composed of multiple consecutive PRBs, as shown in FIG. 3, in FIG. 3, first the full bandwidth is divided into multiple groups by every 10 consecutive PRB groups, assuming that a total of N are obtained group; where each group of N groups takes one PRB to form an interlace, that is, a PRB set with the same index in N groups in FIG. 3, such as index=0. Of course, in this embodiment of the present invention, the resource set is not limited to a group formed by multiple consecutive PRBs. For example, the resource set may be a subcarrier set. That is to say, the granularity of the frequency domain resource may be PRB or an integer multiple of the number of subcarriers, but not a multiple of PRB.

In addition, when all the terminals of the network side device that need to distribute energy-saving signals or the energy-saving signals of one terminal occupy all the interlace in the interlace structure, the energy-saving signals include orthogonal sequences.

For the licensed frequency band, the frequency domain resource of the energy-saving signal of one or more terminals is an interlace structure that occupies part or all of the bandwidth. The interlace structure can occupy part or all of the transmission bandwidth when it is in the licensed frequency band. The energy-saving signal is sent on the interlace allocated to a certain terminal, and the number of interlace allocated by the network-side device to the terminal and its interlace index are semi-statically configured or predetermined. In the example shown in FIG. 3, different terminals use different interlaces. Preferably, when there are a large number of users, different terminals may be assigned the same interlace, which maps the terminals in the terminal group described in the previous embodiment. Energy-saving signals using the same frequency domain resources.

In this embodiment, the basic unit of frequency domain for energy-saving signal transmission is interlace, so that the frequency domain resources can be fully utilized to improve resource utilization. In addition, the interlace structure is adopted so that only the interlace index needs to be indicated during resource configuration, thereby saving signaling overhead.

As an optional embodiment, the energy-saving signal includes m signal subsets, wherein the signal subset i includes n _i sequences, where m>=1, 0=<n _i <=n, i=1,2 ,..m, and n ₁ +n ₂ +,...+n _m =n, where n is the number of sequences included in the energy-saving signal.

In this embodiment, it can be realized that the energy-saving signal includes one or more signal subsets, and the number of sequences included in different signal subsets may be the same or different, for example: a certain signal subset may include 0 sequences, while other signal sub-sets A set can include one or more sequences. In this way, the flexibility of the energy-saving signal can be improved to adapt to the needs of different scenarios, services, or terminals.

Optionally, the energy-saving signal includes at least one of the following sequences: Pseudo-Noise (PN) sequence, ZC sequence, orthogonal sequence, Costa sequence, Kasumi sequence, Primary Synchronization Signal (PSS) sequence, Secondary synchronization signal (Secondary Synchronization Signal, SSS) sequence, synchronization sequence and sequence combination with equivalent functions.

其中，S _CS (n)表示上述Costa序列，Costas序列長度是LM。其中v _l 是一個整數序列，L和M為常數，n為常數，p(n)定義如下，

Wherein, the aforementioned Costa sequence may be a Costa sequence defined in the protocol, or may be a time domain sequence determined by the following formula:

Among them, S _CS ( n ) represents the aforementioned Costa sequence, and the length of the Costas sequence is LM. Where v _l is a sequence of integers, L and M are constants, n is a constant, and p(n) is defined as follows,

For example, to generate a Costas sequence with a length of 256, you can set L=M=16, and v _l uses the following sequence: { v _l }={5 2 8 9 12 4 14 10 15 13 7 6 3 11 1 5}.

In addition, a 256-point frequency-domain sequence can be obtained by 256-point discrete Fourier transform (FFT).

It should be noted that the above formula is only an example of the Costa sequence, which is not limited, for example, it can also be a Costa sequence generated by other formulas.

The above Kasami sequence can be generated by selecting an m sequence a with a period of 2 ⁿ -1 (n is an even number) and sampling the sequence a every 2 ^n/2 +1 numbers to obtain a length of 2 ^n/2 -1 sequence. It can be proved that this sequence is still an m sequence, and this sequence is repeated 2 ^n/2 +1 times to obtain a sequence a′ having the same length as the sequence a. The Kasami sequence can be obtained by adding the a and a'sequences bitwise modulo 2. In addition, when changing the phase of one of the sequences (moving backward or forward), a new Kasami sequence can be obtained.

It should be noted that the above description is just an example, for example, m sequence a is not necessarily periodic, and its length is not necessarily 2 ⁿ -1 (n is even).

Among them, the sequence included in the energy-saving signal can be flexibly configured according to actual needs. In this embodiment, it can be realized that the energy-saving signal includes multiple sequences, so that the function of the energy-saving signal is more powerful, so as to further improve the communication performance of the communication system.

Optionally, the energy saving signal is used to indicate at least one of the following: Wakeup area ID (Wakeup area ID), cell ID (Cell ID), terminal ID (UE ID), carrier information, system information update, distance information and end of data , Where the distance information indicates the distance between the energy-saving signal and the control channel.

Since the energy-saving signal can indicate at least one of the above items, the function of the energy-saving signal can be improved to further improve the communication performance of the communication system.

In addition, in this embodiment, one sequence may indicate one or more of the above items, or one sequence may indicate one of the above items, or multiple sequences may jointly indicate one item, etc., which is not limited .

For example, the same sequence in the energy-saving signal indicates one or more of the wake-up area identification, cell identification, terminal identification, carrier information, system information update, distance information, and end of data. In this way, since one sequence can indicate one or more items, the cost of energy-saving signals can be saved.

For another example: the energy saving signal indicates the wake-up area identification through at least one sequence; and/or the energy saving signal indicates the cell identification through at least one sequence; and/or the energy saving signal indicates the terminal identification through at least one sequence; and/or the energy saving The signal indicates the carrier information through at least one sequence; and/or the energy saving signal indicates the system information update through at least one sequence; and/or the energy saving signal indicates the distance information through at least one sequence; and/or the energy saving signal passes through at least one sequence The sequence indicates the end of the data.

In this way, different functions can be indicated through different sequences to improve the flexibility of the energy-saving signal.

Optionally, the energy-saving signal includes multiple sequences occupying one or more OFDM symbols.

In this embodiment, multiple sequences can occupy the same OFDM symbol, or multiple sequences can occupy multiple OFDM symbols, for example, different sequences occupy different OFDM symbols, or some sequences occupy the same OFDM symbol, while other sequences occupy Different OFDM symbols to increase the flexibility of energy-saving signals.

The following uses different instructions and the energy-saving signal as a wake-up signal to illustrate: For the Wake up area ID indication, the wake-up signal carries multiple information fields, each information field carries a subsequence, and the Wake up area ID maps one of them. Subsequence, for example:

Among them, the multi-level sequence of the wake-up signal occupies one or more OFDM symbols in the time domain, sequence 1 represents the mapping of Wake up area ID information, the preferred sequence 1 is a function of Wake up area ID, such as Wake up area ID is ZC The root index of the sequence. The terminal first detects sequence 1 at the mapped WUS sending position. If it finds that the Wake up area ID of the sequence identifier is the identifier of the Wake up area to which the terminal belongs, it will continue to detect the subsequent sequence, otherwise the terminal stops detecting the subsequent multi-level Sequence, continue to enter the sleep state, which is very conducive to the terminal to save power.

For the Cell ID indication, the wake-up signal carries multiple information fields, each of which carries a subsequence, and the Cell ID maps 1-2 subsequences, for example:

The multi-level sequence of the wake-up signal occupies one or more OFDM symbols in the time domain. Sequences 2 and 3 can reuse PSS/SSS for time-frequency coarse synchronization operation. After the terminal successfully detects the synchronization sequence PSS/SSS, it can identify the Cell ID, preferably sequence 2 and sequence 3 can reuse the PSS/SSS design sequence. The terminal can complete the coarse synchronization after deciphering the Cell ID. The Cell ID can be used to assist the subsequent decoding of the Physical Broadcast Channel (PBCH), such as directly detecting the PSS/SSS in the SSB or removing the PSS based on the sequence ID and the previous synchronization information. The /SSS detection step directly detects the PBCH, thereby implementing fast cell search for the terminal in RRC-connected mode.

For the UE ID indication, the UE ID maps one or more subsequences of the wake-up signal, for example:

Sequence 4 can be used for UE ID indication. For example, a specific method can use the UE ID as initial information to generate a PN sequence as sequence 4, which can occupy one or more OFDM symbols in the time domain. After detecting the previous multi-level sequence belongs to the UE's own sequence, the UE starts to detect the sequence mapped by the UE ID. For example, by judging the peak value of the sliding correlation detection, if the terminal finds that the UE identified by the sequence is itself, it will continue to detect subsequent Sequence, otherwise stop WUS detection and continue to sleep.

For carrier information indication, the carrier information maps to a subsequence of the wake-up signal, for example:

For example, sequence 5 can be used for carrier information indication, such as instructing the base station to activate the carrier information for the terminal. For example, the terminal supports 4 carriers. The base station uses 4-bit [b0 b1 b2 b3] as the index indicator of the activated carrier. Use bit mapping to set the bit for starting carrier mapping to 1, and the bit for not starting carrier mapping to 0, and then use the decimal digital value mapped by the bit mapping vector as The input of the PN sequence or the root index of the ZC sequence obtains the sequence of carrier information mapping. It should be pointed out that the method described in the embodiment of the present invention is the simplest method and does not exclude other methods of carrier indication. After detecting the sequence of carrier information mapping, the terminal can prepare for subsequent power ramping on the carrier. This method effectively avoids the need to detect WUS on multiple radio frequency channels and continues to sleep on the carrier that has not been activated, thus Significantly reduce terminal power consumption.

For the system information update instruction, the system information update instruction maps a subsequence of the wake-up signal, for example:

For example, sequence 6 can be used for system information update instructions. The sequence only needs to distinguish whether the system information needs to be updated, so only two cases are mapped. For example, two orthogonal sequences can be constructed, and sequence 0 indicates that the system information has not been updated. Sequence 1 indicates that the system information needs to be updated. The terminal only needs to detect the mapped sequence at the mapping position to obtain the indication of the system information. If it is found that the system information update flag is carried in the wake-up signal sequence, the terminal will detect new information at the subsequent system information update time. If the wake-up signal does not have the system information update flag, the terminal believes that the downlink data arrives. The terminal in RRC_IDLE and RRC_Inactive mode will detect the downlink control information (DCI) of the page (page), and then detect the PDSCH to receive the data. .

For the distance information between the wake-up signal and the corresponding PDCCH

As shown in FIG. 4, WUS can be considered to be divided into multiple subsets. For example, WUS subset 1 is used to indicate that the terminal will have data to arrive in this DRX cycle. After the terminal correctly recognizes WUS subset 1, it will start power ramping. Prepare for normal reception and measurement operations. However, the location where the terminal receives WUS subset 1 may still be far away from the arrival of the data. In order to avoid the terminal blindly detecting the PDCCH after waking up, a sequence is introduced to indicate the distance from WUS subset 1 to the PDSCH, optional The WUS subset 2 is introduced before the PDCCH or PDSCH, and the distance indicated by the sequence may also be the distance between the WUS subset 1 and the subset 2. The aforementioned distance can be expressed by the number of OFDM symbols, and it is only necessary to use the number of OFDM symbols as the input of a certain sequence, that is, the sequence is a function of the aforementioned distance. In addition to being accurate to OFDM symbols, the distance can also be an estimated value, such as accurate to subframes or time slots. The terminal finds that WUS subset 1 starts power ramping, performs the necessary cell search and radio channel measurement process, but does not perform PDCCH blind detection, and does not start the blind PDCCH detection operation until WUS subset 2 arrives and the detection is successful. Due to the lower complexity of the WUS subset 2 indicating the arrival of the PDCCH, the terminal can start detecting the WUS subset 2 after receiving the WUS subset 1, using the distance indication between the WUS and the PDCCH as further verification, or the two signals can be used to resolve Any one of them will perform PDCCH blind detection. Of course, only one of the two indication information may be retained, such as only WUS subset 2, or only the indication information of the distance between WUS and PDCCH.

For the indication of the end of the data, the energy saving signal is shown in the following table:

After the terminal detects and successfully decodes the data belonging to the subset, it does not know whether the base station will continue to send data to the terminal, so after being activated by WUS, even if the data has ended, it cannot enter the sleep state, so the present invention introduces WUS Another subset of the signal is also composed of a sequence used to indicate whether the base station sends data this time. For a specific method, a sequence can be designed, such as indicating whether the system information has changed, for indicating whether the data ends, as shown in FIG. 5. WUS set 1 is used to indicate the arrival of data, the terminal starts power ramping, WUS set2 is used to start PDCCH detection, WUS set3 is used to detect whether the data is over, and the terminal enters the sleep state if it successfully detects WUS set3. In FIG. 5, in order to facilitate detection, WUS set3 is placed at the last symbol of DRX on, but it does not exclude its position that is more conducive to power saving. For example, WUS set3 is located after PDSCH at a predetermined number of OFDM symbols from PDSCH.

As an optional implementation manner, among the multiple sequences included in the energy-saving signal, part of the sequence is used for the connected terminal, and all the sequence is used for the non-connected terminal.

The working state of the terminal in NR may include: RRC_IDLE, RRC_Inactive and RRC_Connected, these three states, while in LTE the terminal has two working states RRC_IDLE and RRC_Connected. After the terminal in RRC_IDLE mode is awakened by WUS, it takes much longer than the terminal in RRC_Connected to wake up. It needs to perform more operations than RRC_IDLE. WUS may support more functions. For example, as shown in the following table, the preferred energy-saving signals in different states have a nesting relationship. Sequences 1 to n'are used in RRC_Connected mode, and 1 to n are used in RRC_IDLE mode. If the terminal is in RRC_Connected mode, it only needs The detection sequence is 1 to n', which reduces the detection complexity.

In this embodiment, part of the sequence is used for the connected terminal, and the entire sequence is used for the non-connected terminal. This can realize that the network side devices of different state terminals do not need to send different energy-saving signals, thereby reducing transmission overhead.

It should be noted that, in the embodiments of the present invention, the above-mentioned various optional implementation manners may be implemented independently of each other, or may be implemented in combination with each other, which is not limited.

In the embodiment of the present invention, the network-side device determines the transmission resource of the energy-saving signal; the network-side device sends the energy-saving signal through the transmission resource, where the energy-saving signal includes multiple sequences. Thereby, energy-saving signals including multiple sequences can be transmitted, and the communication performance of the communication system can be improved.

The energy saving signal is exemplified below through multiple embodiments.

Example 1

In order to effectively avoid that the base station sends WUS of all users on the same resource, thereby reducing the interference of the UE detecting the wake-up signal and reducing the design difficulty of the wake-up signal, the following design scheme may be adopted.

Method 1: The network first divides the UEs that need to monitor WUS into multiple groups based on the UE ID information, and each group of UEs sends a wake-up signal on the same resource. The UE ID is just a user ID and is not limited to RNTI. For example, the ID information of the UE in the Wake up area/paging area can also be a function of the globally unique identifier of the UE, such as the UE’s The globally unique logo modulo operation.

Method 2: The network divides the UEs that need to monitor WUS into multiple groups based on the UE ID information. Each group of UEs sends wake-up signals on the same frequency domain resources and different time domain resources. The different time domain resources may refer to different OFDM symbols or time slots, for example.

Method 3: The network divides the UEs that need to monitor WUS into multiple groups based on the UE ID information. Each group of UEs sends wake-up signals on the same time-domain resources and different frequency-domain resources. For example, the UE can calculate the difference according to the UE ID. Send a wake-up signal on the PRB resource.

Method four: The network divides the UEs that need to monitor WUS into multiple groups based on the UE ID information. The UEs in the group send wake-up signals on different time-domain resources respectively. The number of users in the group is 1 is a special case of the above scheme. When the number of users in the group is greater than 1, mode 1 has a smaller resource overhead than modes 3 and 4. The above four schemes can be used in combination when necessary. For example, when the wake-up signal contains multiple subsets to be sent, different resource configuration schemes can be considered for each WUS subset.

Example 2

The three schemes described in Embodiment 1 all need to configure the resource for sending the wake-up signal, which is different from the paging signal (paging signal) transmission resource indicated by the PDCCH. The base station needs to determine the time and frequency of WUS transmission before blindly detecting the PDCCH. Resources.

The configuration method of the WUS frequency domain transmission resource is as follows: the base station configures the WUS frequency domain transmission resource for the UE or the UE group in a static or semi-static manner, and the frequency domain resource corresponds to the UE ID. The UE group is determined according to certain rules. For example, the UEs in the group have the same UE ID identification, or the UE IDs in the group are different but satisfy a certain relationship. For example, the UE ID in the group has the same value after modulo a certain value. .

Optionally, the base station may also semi-statically configure resource information related to the UE ID or UE group by WUS through RRC signaling; alternatively, the base station instructs the UE to send WUS according to a pre-agreed or system information indication method. The resource information as a supplementary method of resource configuration cannot be excluded. For example, WUS is divided into multiple subsets, and a subset of the transmission resources is configured using this method; the foregoing transmission resource information generally refers to time-frequency resources, and sometimes includes Beam related information, such as Beam ID.

For an example of an unlicensed band, if each WUS occupies a part of the transmission bandwidth, the wake-up signal may not meet the regulation of the occupied channel bandwidth (Occupied Channel Bandwidth, OCB), so it is better to use WUS Use the interlace structure that occupies the full bandwidth, as shown in Figure 3. In Fig. 3, first, the full bandwidth is divided into multiple groups by every 10 consecutive PRBs. Assume that a total of N groups are obtained; in the aforementioned N groups, each group takes one PRB to form an interlace (that is, N in Fig. 3) PRB sets with the same index in each group, such as index=0). The basic unit of frequency domain for WUS transmission is interlace. The foregoing interlace is just an example. In each group, the granularity of the frequency domain resources allocated to each UE may be PRB or an integer multiple of the number of subcarriers, but not a multiple of PRB. The aforementioned interlace structure is full-bandwidth in the unlicensed band, and the interlace can occupy part or all of the transmission bandwidth when in the licensed band. The base station sends WUS on the interlace allocated to a certain UE. The number of interlace allocated by the base station to the UE and its interlace index are semi-statically configured or pre-agreed. In the example shown in FIG. 3, different UEs use different interlaces. Preferably, when there are a large number of users, different UEs can be assigned the same interlace, which corresponds to the situation in which users in the group occupy the same resources in Embodiment 1. . The present invention certainly does not exclude the special case that one UE occupies all interlace. In this case, each UE actually occupies the full bandwidth, and the WUS signal is an orthogonal sequence.

The configuration method of the WUS time-domain transmission resources is as follows: the base station determines the possible transmission period of the UE-specific wake-up signal according to the UE ID and the DRX cycle, and sends the wake-up signal in the WUS transmission cycle before the data transmission. WUS can be composed of multiple subsets. The base station needs to send certain subsets of the wake-up signal at a position determined before each DRX cycle or within DRX according to the UE ID information, and dynamically send WUS on certain OFDM symbols. The other parts are shown in Figure 4. Subset 1 of WUS is sent in subframe M. The base station and terminal with the better sending position use the agreed algorithm, or the semi-static configuration of the base station makes the base station and terminal transparent to the position. When the algorithm is used to calculate The location is a function of the UE ID and DRX cycle, when semi-static configuration is used, it is better to notify through UE-specific RRC signaling; if WUS subset 2 exists, it is sent after WUS subset 1, send this The position of the subset is related to the real starting point of the data. The position is dynamic and cannot be determined before the WUS subset 1 is sent. It also has a definite mapping relationship with the subset of the sent WUS subset 1; Figure 4 only describes WUS The two subsets of do not exclude the existence of other subsets of WUS. If the terminal detects WUS, the terminal starts a timer. The timer has a threshold configured by the base station. If the timer times out but does not detect its own PDCCH, the terminal will re-enter the sleep state.

It should be noted that Embodiment 1 and Embodiment 2 correspond to the implementation manner of transmission resource configuration in the embodiment shown in FIG. 2, and in addition, Embodiment 1 and Embodiment 2 may not limit the energy saving signal to include multiple sequences, that is, In other words, in the technical solutions corresponding to Embodiment 1 and Embodiment 2, the energy-saving signal may include one sequence.

Example 3
