In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with 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, where the terminal 11 may be a user terminal (User Equipment, UE) or Other terminal devices, such as: mobile phones, tablets (Tablet Personal Computer), laptop computers (Laptop Computer), personal digital assistants (PDA), mobile Internet devices (Mobile Internet Device, MID) or wearables For terminal-side devices such as wearable devices, it should be noted that the specific types of terminals are not limited in the embodiments of the present invention.

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-mentioned 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 sale of detection related to the decoding of the control channel. For example, the energy-saving signal may be a wakeup signal (Wakeup Signal, WUS). Of course, this is not limited. For example, the energy-saving signal may also be other signals defined in the agreement, or other signals pre-appointed by the network side device and the terminal.

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

In addition, in the embodiment of the present invention, the same sequence indication can indicate one or more functions. For example, a certain sequence can indicate Wake up area ID, Cell ID, terminal ID, carrier information, One or more of system information update, distance information, and data end. Since the energy-saving signal includes multiple sequences, the energy-saving signal can indicate multiple functions to the terminal. After receiving the energy-saving signal, the terminal can parse the instructions of these functions, and then perform corresponding actions. For example: wake up, check control channel, check data channel, get 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-mentioned 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 a non-active state (RRC_Inactive) terminal. In some embodiments, the same energy-saving signal can be applied to both connected and non-connected terminals, so that the energy-saving signal has a nested feature, thereby saving transmission resources.

In this way, through three or more sequences, the energy-saving signal can achieve more functions, thereby further improving the communication performance of the communication system.

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, the grouping of the terminals may be based on the terminal identification (UE ID) of the terminal. For example, the terminals in the same terminal group have the same UE ID, or the UE IDs of the terminals in the same terminal group are different but satisfy certain requirements. For example, the UE ID of the terminal in the same terminal group in the group has the same value after modulo a certain value. In addition, the UE ID in the embodiment of the present invention may be a user identity, and is not limited to a radio network temporary identity (RNTI). For example, it may be a terminal in a wake up area (Wake up area) or paging. The ID information in the paging area may also be a function of the global unique identification of the terminal, for example, it may be a modulo operation of the global unique identification of the terminal.

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 signal of all the 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 the terminals in the same terminal group uses the same transmission resource, and the transmission resource includes 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 resource includes 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 resource, 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 resource, and at least one signal from 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 foregoing one or more signal subsets may be referred to as one or more subsets of an energy-saving signal, and of course, it may also be referred to as one or more different energy-saving signals. In addition, the transmission resources of different signal subsets may be different, for example: different signal subsets are sent on different time domain resources.

The foregoing at least one signal subset of the terminals in the same terminal group using the same transmission resource may mean that all signal subsets of the terminals in the same terminal group use the same time domain resource and frequency domain resource; or, in the same terminal group Some signal subsets of the terminal use the same time domain resources and frequency domain resources, while other signal subsets use the same time domain resources but different frequency domain resources, or other signal subsets use 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 contains multiple signal subsets to be sent, it is possible to consider different resource allocation schemes for each signal subset.

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

The foregoing at least one signal subset of the terminals in the same terminal group adopts different transmission resources, which may be that all or part of the signal subsets of the terminals in the same terminal group adopt different time domain resources and frequency domain resources.

In this embodiment, since at least one signal subset of the terminals in the same terminal group uses different transmission resources, flexible configuration can be performed 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 terminals in the same terminal group uses the same time domain resource, and at least one signal subset of different terminals in the same terminal group uses different frequency domain resources may mean that all signal subsets in the same terminal group Sets use the same time domain resources, and 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 domain 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 may mean that all signal subsets in the same terminal group Sets use the same frequency domain resources, and different signal subsets use different time domain resources, or it can mean that part of the 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 signal subsets. Time domain resources. In this way, different energy-saving signals can be sent to multiple terminals in the same frequency domain resource, so that the frequency domain resources of the terminal can be saved.

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 (Physical Resource Block, PRB), or may be a subcarrier, or may also be a frequency domain resource unit, 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 is a terminal or a terminal group, determining the frequency domain resource of the energy-saving signal corresponding to the terminal identifier; 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 terminal UE IDs in the same terminal group in the group have the same value after modulo a certain value. .

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

Since the determined frequency domain resource and the time domain resource correspond to the terminal identifier, it is possible to realize that no additional information needs to be added when determining the frequency domain resource and the time domain resource, so as to reduce the implementation complexity.

Optionally, 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 identifier includes: the network-side device determines the terminal or terminal group with the terminal identifier 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 (DRX) Period, which determines the time domain resource of the energy-saving signal of the terminal.

Wherein, the above-mentioned 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 uses Radio Resource Control (RRC) The signaling is semi-static, which determines the frequency domain resource of the energy-saving signal corresponding to the terminal identifier for the terminal or terminal group; or the network side device determines the terminal or terminal group corresponding to the terminal identifier through pre-appointment or system information instructions The frequency domain resources of the energy-saving signal.

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

As an optional implementation manner, the energy-saving signal includes a plurality of signal subsets, wherein a part of the signal subset is located before another part of the signal subset.

Among them, the time domain resources of the other part of the signal subset can be dynamically configured. For example, the energy-saving signal includes signal subset 1 and signal subset 2. Among them, signal subset 1 precedes signal subset 2, and signal subset 2. The time domain resource of is related to the actual sending start point of the data. For example, the interval between the time domain resource of signal subset 2 and the actual sending start point of the data is related to 0, or the interval is within a preset range, and so on. The time domain resources of the above-mentioned partial signal subsets may be statically or semi-statically configured.

It should be noted that this embodiment is not limited to being applied to DRX scenarios. For example, in a non-DRX scenario, the energy-saving signal 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-mentioned partial signal subset may be based on the terminal identifier and the DRX cycle. In the case that the energy-saving signal includes multiple signal subsets, the network-side device determines the time-domain resource of the energy-saving signal of the terminal according to the terminal identification and the DRX cycle, which may include: the network-side device determines the energy-saving of the terminal according to the terminal identification The time domain resources of a part of the signal subset of the signal are before or within the DRX cycle, wherein the other part of the signal subset is dynamically transmitted on the OFDM symbol.

In this implementation manner, it is possible to determine that part of the signal subset time domain resources are before or within the DRX cycle, while the other part of the signal subset is dynamically transmitted, thereby improving the flexibility of energy-saving signal transmission and reducing 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 and achieve the purpose of energy saving.

Of course, in the embodiment of the present invention, the network side device determines the time domain resource of the energy-saving signal of the terminal according to the terminal identifier and the DRX cycle, or it can determine the time domain 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 are not limited. For example, for a non-DRX scenario, the time domain resource corresponding to the terminal identifier can 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 based on the terminal identification can also be determined by a predetermined algorithm based on the terminal identification, or based on the semi-static configuration of the terminal identification. limited. In addition, some parameters in the above algorithm can be semi-statically configured.

Optionally, the time domain resources of the partial signal subset are determined by a predetermined algorithm; and/or the time domain resources of the partial signal subset are semi-statically configured by the network side device.

Wherein, in the above and/or representation, the time domain resources of some signal subsets may be configured through a pre-appointed algorithm and/or semi-statically. For example, the above algorithm may include semi-statically configured parameters such as the DRX cycle may be semi-statically configured.

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

For example: if the time domain resources of the partial signal subset are determined by the algorithm, the position of the time domain resources of the partial signal subset is a function of the terminal identifier and the DRX cycle; and/or if the time domain of the partial signal subset The domain resources are semi-statically configured by the network-side equipment, and the time domain resources of this part of the signal subset are notified through terminal-specific RRC signaling.

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

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

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

Among them, the aforementioned unlicensed frequency bands may include unlicensed frequency bands, and of course, may also refer to unlicensed frequency bands other than unlicensed frequency bands. The aforementioned interlace structure that occupies the full bandwidth may be an interlace structure that occupies 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 different resource sets. Resources with the same index in.

For example, the resource set is a group consisting of multiple continuous PRBs, as shown in Figure 3. In Figure 3, first, the full bandwidth is divided into multiple groups with each group of 10 continuous PRBs, assuming a total of N group; among them, each of the N groups takes one PRB to form an interlace, that is, a set of PRBs with the same index (index) in the N groups in FIG. 3, such as index=0. Of course, in the 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. In other words, the granularity of frequency domain resources can be PRB, or an integer multiple of the number of subcarriers, but not a multiple of PRB.

In addition, when the network-side equipment needs to distribute all the terminals of the energy-saving signal or when the energy-saving signal of one terminal occupies all the interlaces in the interlace structure, the energy-saving signal includes an orthogonal sequence.

For the authorized 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. When in the authorized frequency band, the interlace structure can occupy part or all of the transmission bandwidth. The energy-saving signal is sent on the interlace allocated for a certain terminal, and the number of interlace allocated by the network side device for the terminal and its interlace index are semi-statically configured or pre-appointed. In the example shown in Figure 3, different terminals use different interlaces. Preferably, when the number of users is large, different terminals can be assigned the same interlace, which corresponds to the terminal groups in the terminal group described in the previous embodiment. The energy-saving signal uses the same frequency domain resources.

In this embodiment, the basic unit of frequency domain that can realize energy-saving signal transmission is interlace, which can make full use of frequency domain resources to improve resource utilization. In addition, the interlace structure is adopted so that when resources are configured, only the interlace index needs to be indicated, thereby saving signaling overhead.

As an optional implementation manner, the energy-saving signal includes m signal subsets, where 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 subsets may include 0 sequences. The 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 (SSS) sequence, synchronization sequence with equivalent function, and sequence combination.

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

Wherein, S _CS ( n ) represents the aforementioned Costa sequence, and the length of the Costas sequence is LM. Where v _l is an integer sequence, 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 through 256-point discrete Fourier Transformation (FFT).

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

The above Kasami sequence can be generated in the following way: select an ^{m sequence a with a period of 2 n} -1 (n is an even number), ^{and sample 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. Repeat this sequence 2 ^n/2 +1 times to obtain a sequence a'with the same length as the a sequence. A Kasami sequence can be obtained by adding a and a'sequence bit by bit modulo 2. In addition, when one of the sequence phases is changed (backward or forward), a new Kasami sequence can be obtained.

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

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, and the communication performance of the communication system is further improved.

Optionally, the energy saving signal is used to indicate at least one of the following: Wakeup area ID, Cell ID, UE ID, carrier information, system information update, distance information, and data end , 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 data end. In this way, since a sequence can indicate one or more items, the overhead of energy-saving signals can be saved.

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

In this way, different sequences can be used to indicate different functions, so as to improve the flexibility of energy-saving signals.

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 occupy multiple OFDM symbols, for example: different sequences occupy different OFDM symbols, or some sequences occupy the same OFDM symbols, while other sequences occupy the same OFDM symbols. Different OFDM symbols to improve the flexibility of energy-saving signals.

The following is an example according to different instructions, and the energy-saving signal is the wake-up signal: For the Wake up area ID indicator, the wake-up signal carries multiple information fields, each information field carries a sub-sequence, and the Wake up area ID maps to one of them. Subsequence, for example:

Among them, the multi-level sequence of the wake-up signal respectively occupies one or more OFDM symbols in the time domain. Sequence 1 indicates the mapping of Wake up area ID information. The preferred sequence 1 is a function of Wake up area ID, for example, Wake up area ID is ZC The root index of the sequence. The terminal first detects sequence 1 at the corresponding WUS sending position. If it finds that the Wake up area ID identified by the sequence is the identifier of the Wake up area to which the terminal belongs, it will continue to detect the following sequence, otherwise the terminal will stop detecting the following multiple levels Sequence, continue to enter the sleep state, which is very helpful for the terminal to save power consumption.

For the Cell ID indication, the wake-up signal carries multiple information fields, each information field carries a sub-sequence, and the Cell ID maps 1-2 sub-sequences, 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 coarse time-frequency synchronization. After the terminal successfully detects the synchronization sequence PSS/SSS, it can identify the cell. ID, better sequence 2 and sequence 3 can reuse PSS/SSS design sequence. After the terminal decodes the Cell ID, the coarse synchronization can be completed, and 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 realizing fast cell search for terminals 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 UE ID as initial information to generate a PN sequence as sequence 4. The sequence can occupy one or more OFDM symbols in the time domain. After the UE detects that the previous multi-level sequence belongs to the UE's own sequence, it starts to detect the sequence corresponding to the UE ID. For example, the peak value of sliding correlation detection is judged. 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 the carrier information indicator, the carrier information corresponds to a sub-sequence of the wake-up signal, for example:

For example, sequence 5 can be used for carrier information indication, for example, to indicate the carrier information that the base station activates for the terminal. For example, the terminal supports 4 carriers. The base station uses 4 bits [b0 b1 b2 b3] as the index indication of the activated carrier. Use bit mapping to set the bit to start the carrier mapping to 1, and set the bit to 0 for the unactivated carrier mapping, and then use the decimal value of the bit mapping vector mapping as The input of the PN sequence or the root index of the ZC sequence obtains the sequence corresponding to the carrier information. It should be pointed out that the method described in the embodiment of the present invention is the simplest method, and other carrier indication methods are not excluded. After the terminal detects the sequence of carrier information mapping, it can prepare for subsequent power ramping on the carrier. This method effectively avoids the need to detect WUS on multiple RF channels and continue to sleep on the unactivated carrier. Significantly reduce terminal power consumption.

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

For example, sequence 6 can be used for system information update instructions. This sequence only needs to distinguish whether the system information needs to be updated, so it only maps two cases. For example, two orthogonal sequences can be constructed. Sequence 0 means that the system information is not updated. Sequence 1 indicates that the system information needs to be updated. The terminal only needs to detect the corresponding sequence at the mapping position to obtain the system information instructions. If it is found that the system information update flag is carried in the wake-up signal sequence, the terminal will detect the new information at the following system information update time. If the wake-up signal does not have a system information update flag, the terminal believes that the downlink data has arrived, and the terminal in RRC_IDLE, RRC_Inactive mode will detect the Downlink Control Information (DCI) of the page (page), and then detect the PDSCH for data reception .

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

As shown in Figure 4, you can consider dividing WUS into multiple subsets. For example, WUS subset 1 is used to indicate that the terminal will have data arriving in this DRX cycle. After the terminal correctly recognizes WUS subset 1, the power ramp will start. Prepare for normal reception and measurement operations. However, the location where the terminal receives WUS subset 1 may still be far away from the data arrival. In order to prevent the terminal from blindly detecting the PDCCH after waking up, a sequence is introduced to indicate the distance of WUS subset 1 from the PDSCH arrival, optional WUS subset 2 is introduced before PDCCH or PDSCH, and the distance indicated by the sequence can also be the distance between WUS subset 1 and 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 the OFDM symbol, the distance can also be an estimated value, such as accurate to a sub-frame or time slot. The terminal discovers that WUS subset 1 starts to start power ramping, and performs necessary cell search and wireless channel measurement processes, but does not perform blind PDCCH detection. It does not start blind PDCCH detection until WUS subset 2 arrives and the detection is successful. Since the WUS subset 2 indicating the arrival of the PDCCH is less complex, the terminal can start to detect the WUS subset 2 after receiving the WUS subset 1, and use the WUS and PDCCH distance indicator as a further verification, and the two signals can also be resolved. Blind detection of the PDCCH is performed on any one of them. Of course, only one of the two indication information can be kept, such as only WUS subset 2, or only WUS and PDCCH distance indication information.

For the indication of the end of the data, the energy-saving signals are 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. Therefore, after being activated by WUS, even if the data has ended, it cannot enter the sleep state. Therefore, the present invention introduces WUS Another subset of the signal is also composed of a sequence to indicate whether the base station has finished sending data this time. For a specific method, a sequence can be designed, such as indicating whether the system information has changed, and used to indicate whether the data is over, as shown in Figure 5. WUS subset (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 a sleep state if it successfully detects WUS set3. In FIG. 5, for the convenience of detection, WUS set3 is placed at the last symbol of DRX on, but it does not rule out a position that is more conducive to power saving. For example, WUS set3 is located behind the PDSCH at a distance from the PDSCH to the agreed number of OFDM symbols.

As an optional implementation manner, among the multiple sequences included in the energy-saving signal, some of the sequences are used for connected terminals, and all of the sequences are used for non-connected terminals.

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

In this embodiment, since part of the sequence is used for connected terminals and the entire sequence is used for non-connected terminals, it is possible to realize that network side devices of terminals in different states 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 multiple optional implementation manners provided above can be implemented independently or 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 a plurality of 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 will be exemplified below through a number of embodiments.

Example 1

In order to effectively prevent the base station from sending the WUS of all users on the same resource, thereby reducing the interference of the UE in detecting the wake-up signal, and reducing the difficulty in designing the wake-up signal, the following design solutions can 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 only a user ID and is not limited to RNTI. For example, it can be the ID information of the UE in the Wake up area/paging area, or it can be a function of the global unique ID of the UE, for example, it can be the UE's ID information. Globally unique identification of modulo operation.

Method 2: The network divides the UEs that need to monitor WUS into multiple groups based on the UE ID information, and 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 resource and different frequency domain resources. For example, the difference calculated based on the UE ID A wake-up signal is sent on the PRB resource of the device.

Method 4: The network divides the UEs that need to monitor WUS into multiple groups according to the UE ID information, and the UEs in the group send wake-up signals on different time domain resources. 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 one has a smaller resource overhead than modes three and four. The above four schemes can be used in combination when necessary. For example, when the wake-up signal contains multiple subsets to be sent, it is possible to consider different resource allocation schemes for each WUS subset.

Example 2

The three schemes described in Embodiment 1 all need to configure resources for sending wake-up signals. Unlike the sending resources for paging signals indicated by the PDCCH, the base station needs to pre-determine the time and frequency of WUS sending before blindly detecting the PDCCH. Resources.

The method for configuring 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, or the UE IDs in the group are different but satisfy a certain relationship. For example, the UE IDs in the group have the same value after modulo a certain value. .

Optionally, the base station can also semi-statically configure the resource information sent by WUS related to the UE ID or UE group through RRC signaling; optionally, the base station instructs the UE to send WUS according to a pre-arranged or system information indication method. As a supplementary method for resource allocation, WUS can’t be ruled out. For example, WUS is divided into multiple subsets and a certain subset of the resources is configured using this method; the aforementioned resource information generally refers to time-frequency resources, and sometimes includes Beam-related information, such as Beam ID.

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

The method for configuring 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 period, and sends the wake-up signal in the WUS transmission period 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 location determined before or within the DRX cycle 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 the terminal with a better sending position pass the agreed algorithm, or the semi-static configuration of the base station makes the base station and the terminal transparent to the position, when the algorithm is used to calculate When the position is a function of the UE ID and the DRX cycle, when semi-static configuration is adopted, it is preferably notified through UE-specific RRC signaling; if WUS subset 2 exists, it will be sent after WUS subset 1. The location of the subset is related to the actual sending start point of the data. The location is dynamic and cannot be determined before WUS subset 1 is sent.

Example 3

The base station sends a wake-up signal composed of a multi-level sequence. The wake-up signal consists of n sequences. The preferred n sequences can be divided into m, m>=1 subsets, and each subset contains 0=<ni<=n, i=1,2,..m The sequence constitutes the WUS subset i, and n1+n2+,...+nm=n.

These n sequences can be one or more of PN sequence (such as m sequence, gold sequence), ZC sequence, orthogonal sequence, Costa sequence, Kasumi sequence, etc.; use n sequences and m subsets to send wake-up signals to support Part or combination of the following functions: indicating Wakeup area ID, Cell ID, UE ID, carrier information, system information update, indicating the distance information between the wakeup signal and the corresponding PDCCH, and indicating the end of the data.

Example 4:

In the embodiment of the present invention, the described multi-level wake-up signal or multi-level energy saving signal may be composed of different single-level signals, and the base station may notify the terminal through signaling, such as semi-static signaling, or more specifically, through RRC signaling. Those single-level energy-saving signals that are used, that is, the number of single-level signals in the multi-level energy-saving signals are variable, so the function of the multi-level energy-saving signals is also variable, and of course the system overhead is also variable. For example, the multi-level energy-saving signal or wake-up signal includes at most Nmax single-level energy-saving signals, and the base station uses signaling such as bit mapping to indicate that the indication information includes Nmax binary bits, respectively The identifier corresponding to the preset multi-level energy-saving signal, when the multi-level energy-saving signal is used, the corresponding bit is set to 1. Of course, signaling with fewer bits can also be used, such as defining several candidates for multi-level sequence combinations, and different sequence combinations can be notified by signaling. This solution can reduce the overhead of the aforementioned multi-level wake-up signal or multi-level energy-saving signal, and provide more flexibility for the network. The notification signaling is preferably semi-static signaling as described above, but other signaling, such as dynamic signaling, is not excluded.
