Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mobile communication, and particularly relates to a sidelink wake-up method, device and terminal. BACKGROUND

[0002] The Long Term Evolution (LTE) system supports sidelink, also known as side link or edge link, for direct data transmission between user equipment (UE) such as terminals without going through a network device. The design of the LTE sidelink is suitable for specific public safety events, such as emergency communication in fire sites or disaster sites such as earthquakes, or vehicle to everything (V2X) communication. Vehicle to everything communication includes various services, such as basic safety class communication, advanced (automatic) driving, platooning, sensor extension, and the like. Since the LTE sidelink only supports broadcast communication, it is mainly used for basic safety class communication, and other advanced V2X services with strict QoS requirements in terms of latency, reliability, and the like will be supported by the NR sidelink. The 5G NR system can be used in a frequency band of 6 GHz or above which is not supported by the LTE, and supports a larger working bandwidth. The sidelink link interface can also be referred to as a PC5 interface. The current sidelink transmission is mainly divided into broadcast, groupcast, and unicast transmission forms. Unicast is a transmission of one to one. Groupcast is a transmission of one to many. Broadcast is also a transmission of one to many, but broadcast does not have the concept of UEs belonging to the same group. The current sidelink unicast and groupcast communication supports a physical layer hybrid automatic repeat request (HARQ) feedback mechanism.

[0003] In the 5G system, in order to further improve the power saving performance of the UE, a wake-up signal (WUS) based on a physical downlink control channel (PDCCH) is introduced. The role of the WUS is to inform the UE whether it needs to monitor the PDCCH during a specific discontinuous reception (DRX) monitoring period (onDuration). When there is no data, the UE can not need to monitor the PDCCH during the onDuration, which means that the UE can be in a sleep state during the entire DRX cycle, such as a DRX long cycle, thereby further saving power. The WUS signal is a downlink control information (DCI), referred to as DCP (DCI with CRC scrambled by PS-RNTI), wherein the PS-RNTI is a radio network temporary identifier (RNTI) specially allocated by the network for the UE for power saving characteristics. The DCI scrambled by the RNTI carries the wake-up / sleep indication of the network to the UE. The UE decides whether to start the onDuration timer and whether to perform PDCCH monitoring in the next DRX cycle according to the indication.

[0004] When performing sidelink communication, the source address (PC5 layer 2 source ID, sourceL2 ID) and the destination address (Layer 2 destination ID, destination L2 ID) of the sidelink are used to identify a sidelink and the two end UEs. Generally, the L2 ID is relatively long, which can be 24 bits, and cannot be directly placed in the physical layer (PHY layer) sidelink control information (SCI). Therefore, the SCI overhead needs to be controlled, and the following segmentation method can be adopted:

[0005] - The lowest 8 bits of the source L2 ID (source L1 ID) are carried in the PHY SCI;

[0006] - The remaining 16 bits of the source L2 ID are carried in the medium access control (MAC) header;

[0007] - The lower 16 bits of the Destination L2 ID (destination L1 ID) are carried in the PHY SCI;

[0008] - The upper 8 bits of the Destination L2 ID are carried in the MAC Header.

[0009] Because only part of the bits of the L2 ID are included in the SCI, it is possible that the L1 ID of one SCI matches, but when the complete L2 ID in the MAC Header is parsed, a mismatch is found, resulting in a false detection or confusion phenomenon.

[0010] In a sidelink link, in order to be resource efficient, shared resources are generally used for transmission. When only the L1 ID is carried in the WUS signal, there may be a problem of L1 ID confusion, which causes the receive end (Receive UE, RX UE) to receive interference of the WUS signal transmitted by the wrong transmit end (Transport UE, TX UE), so that the RX UE cannot keep good synchronization with the corresponding TX UE, resulting in waste of resources or failure to achieve power saving effect. SUMMARY

[0043] The sidelink wake-up method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0044] As shown in Figure 2 The execution subject of the sidelink wake-up method provided by the embodiments of the present application can be a first terminal, which is a terminal receiving wake-up information (WUS). In other words, the method can be executed by software or hardware installed in the first terminal. The method can include the following steps.

[0045] In step S210, the first terminal acquires configuration information of a first resource used for transmitting the WUS.

[0046] Before the second terminal transmits the WUS to the first terminal, the configuration information of the first resource for transmitting the WUS needs to be configured for the first terminal and the second terminal.

[0047] The first resource can be determined by the time domain position and / or the frequency domain position of the first resource. In an embodiment, the configuration information of the first resource includes time domain configuration parameters and / or frequency domain configuration parameters of the first resource, which are respectively used to determine the time domain position and / or the frequency domain position of the first resource.

[0048] The time domain position and / or the frequency domain position of the first resource can be configured according to actual needs. In an embodiment, since the time domain position of the first resource is strongly related to the starting position of the on duration of the DRX cycle, the WUS can be required to appear in a position or window that is offset by an offset parameter interval from the starting position of the on duration of each DRX cycle. At this time, the time domain configuration parameters include at least one of the following:

[0049] An offset parameter, wherein the offset parameter is used to indicate the deviation value between the starting time of the first resource and the starting time of the on duration of the DRX cycle of the first terminal in the current DRX cycle.

[0050] A window size, wherein the window size is used to indicate the time domain span of the first resource.

[0051] The frequency domain configuration parameters can be configured in an explicit or implicit manner.

[0052] In an embodiment, according to whether the first resource is a resource corresponding to the sidelink of the first terminal only, the first resource can be at least one of the following:

[0053] A dedicated resource for transmitting the first WUS, that is, the WUS transmitted by the dedicated resource is the first WUS expected to be received by the first terminal;

[0054] A shared resource for transmitting the WUS, that is, the WUS transmitted by the shared resource can not be the first WUS expected to be received by the first terminal.

[0055] Further, the manner in which the first terminal obtains the configuration information of the first resource includes at least one of the following:

[0056] receive a signaling message sent by a network side or a base station, the signaling message containing configuration information of the first resource, wherein the signaling message can be radio resource control (RRC) signaling, pre-configuration signaling, system information block signaling (SIB signaling), dedicated signaling, or the like;

[0057] receive configuration information of the first resource sent by a second terminal; wherein the second terminal is a terminal sending the first WUS, in a unicast link, another terminal corresponding to the first terminal, in a groupcast or broadcast link, another terminal other than the first terminal.

[0058] In step S220, the first terminal receives the first WUS based on the first resource, and determines whether to perform or not to perform a wake-up operation in a target period of discontinuous reception according to the first WUS; wherein the first WUS is determined by the first terminal, and corresponds to a WUS of a sidelink in which the first terminal is located.

[0059] In the case that the first terminal receives the first WUS through the dedicated resource, it is determined according to the first WUS whether to wake up in the on duration of the target DRX cycle to perform listening and receiving of control information and data information.

[0060] In the case that the first terminal receives at least one first WUS through the shared resource, it is determined according to a preset rule whether to wake up in the on duration of the target DRX cycle to perform listening and receiving of control information and data information.

[0061] Wherein, the target DRX cycle can be a current DRX cycle or a next DRX cycle or a certain DRX cycle thereafter, for the sake of simplicity, in the following embodiments, the next DRX cycle is taken as an example.

[0062] From the technical solutions provided by the above embodiments, it can be seen that the embodiments of the present application obtain the configuration information of the first resource by the first terminal, the first resource being used for transmitting the wake-up information; the first terminal receives the first wake-up information based on the first resource, and determines whether to perform or not to perform the wake-up operation in the target period of discontinuous reception according to the first wake-up information; wherein the first wake-up information is determined for the first terminal, and corresponds to the wake-up information of the sidelink where the first terminal is located, so that even in the case of false detection or confusion of the wake-up signal, the first terminal can reasonably perform the wake-up operation to control information and data information listening and receiving, save resources, and achieve the effect of power saving.

[0063] Based on the above embodiments, further, as shown in Figure 3 In the case of the first resource being the dedicated resource, the method comprises the following steps.

[0064] Step S210, the first terminal obtains the configuration information of the first resource, and the first resource is used for transmitting the WUS.

[0065] The step S210 can implement Figure 2 the method embodiment of step S210, and obtain the same technical effect, and the repeated part will not be described here.

[0066] In the case of the first resource being the dedicated resource, the step S210 embodiment can be various, and the embodiments of the present application provide several embodiments based on different types of links.

[0067] For the PC5 unicast link, one-to-one communication is performed between the first terminal and the second terminal, and the configuration information of the dedicated resource for transmitting the WUS needs to be configured for the pair of terminals.

[0068] In an embodiment, since the resources in the system are uniformly managed and controlled by the network side or the base station (gNB), the dedicated resource for transmitting the WUS should also be authorized and permitted by the network side or the base station. When the second terminal is in the connected (RRC Connected) state, the PC5 DTX configuration of the second terminal can be configured by the serving base station (serving gNB) corresponding to the second terminal, at this time the serving base station can also provide the configuration information of the dedicated resource for transmitting the WUS to the second terminal, and then send it to the first terminal by the second terminal.

[0069] In another implementation, when the second terminal is in an Idle state or an Inactive state, although the second terminal can obtain and determine the PC5 DRX configuration by itself in the above state, since the transmission WUS needs a dedicated resource, when the second terminal needs the dedicated resource, the second terminal needs to first perform state conversion, enter the RRCConnected state, and then request the network side or the base station for configuration.

[0070] In another implementation, when the second terminal is in an Out of Coverage (OOC) state, since the OOC state cannot search for any service base station that can provide PC5 service, the second terminal cannot obtain the configuration information of the dedicated resource for transmitting the WUS from the network side or the base station. When the second terminal cannot obtain the configuration information of the dedicated resource, if the first terminal is in a connected state or can be converted to a connected state, the first terminal can first obtain the configuration information of the dedicated resource from the service base station corresponding to the first terminal, and then send the configuration information of the dedicated resource to the second terminal through the sidelink interface, for example, the PC5 RRC process. The network side or the base station sends the configuration information of the dedicated resource to the first terminal, which can be triggered according to the current environment or demand, or based on the monitored state of the second terminal, or based on the related request sent by the first terminal.

[0071] For the PC5 groupcast / broadcast link, one-to-many communication is performed between terminals, and at this time, the configuration information of the dedicated resource for transmitting the WUS needs to be configured for a group of terminals.

[0072] In an implementation, the configuration information of the dedicated resource can be configured to each terminal including the first terminal and the second terminal through dedicated signaling.

[0073] In another implementation, since the groupcast / broadcast link involves many terminals and does not support PC5 RRC, the dedicated signaling configuration has large overhead and delay, and is not a good choice, so public signaling configuration can be adopted, which can include pre-configuration signaling, SIB signaling, etc.

[0074] In another embodiment, for the first terminal or the second terminal in the OOC state, the DRX parameter configuration can be obtained through pre-configuration signaling, and the configuration information of the dedicated resource can also be obtained through pre-configuration signaling.

[0075] In another embodiment, for the first terminal or the second terminal in the Idle / inactive state, the DRX parameter configuration can be obtained through SIB signaling, and the configuration information of the dedicated resource can also be obtained through SIB signaling.

[0076] In another embodiment, for the first terminal or the second terminal in the Connected state, the DRX parameter configuration can also be obtained through SIB signaling, and the configuration of the dedicated resource can also be obtained through SIB signaling. In individual cases, the Connected UE cannot read the SIB, and the SIB content can also be forwarded through dedicated signaling.

[0077] In another embodiment, it is guaranteed by the network side implementation that, for terminals in different states, the dedicated resources configured through pre-configuration signaling, SIB signaling and dedicated signaling are completely consistent, and can communicate together.

[0078] In an embodiment, the offset parameter and / or window size corresponding to each sidelink is configured by the network side or base station. In the case where the starting position of the on Duration, start time, is calculated by the destination L2 ID and the DRX cycle formula, for example, start time = destination L2 ID mod cycle length, in order to stagger the time domain positions corresponding to different destination L2 IDs as much as possible to avoid resource preemption. Since in this case, different destination L2 IDs can derive the same start time, if the configuration information of each dedicated resource is a fixed offset about the start time, then the dedicated resources corresponding to different destination L2 IDs may coincide, for which the network side or base station needs to reasonably allocate destination L2 IDs or introduce more fine-grained distinction to dedicated resources to avoid as much as possible. For example, if the network side or base station can ensure that the start times of different destination L2 IDs are scattered without repetition, then the dedicated resources corresponding to each sidelink can be distinguished, or the network side or base station allocates different dedicated resources to different destination L2 IDs with the same start time according to a preset order, for example, from small to large, which can also ensure the distinction of the dedicated resources of each sidelink.

[0079] Step S221, the first terminal receives the wake-up information received through the first resource as first wake-up information.

[0080] Step S222, determining whether to perform or not to perform a wake-up operation in the target period of discontinuous reception according to the first wake-up information.

[0081] Since the dedicated resource for transmitting the WUS is only for one sidelink, it does not need to carry additional link information, and there is no misjudgment or confusion. The only disadvantage is that a large number of dedicated resources need to be divided and configured, which will affect the overall resource allocation and the resources of other users, so the dedicated resource can be used in the case of light system load or for important sidelinks.

[0082] After the first terminal and the second terminal acquire the same configuration information of the dedicated resource for transmitting the WUS, the second terminal will send the WUS through the dedicated resource, which can be a bit signal, for example, an on / off indication of 1 bit. The first terminal will determine the WUS received through the dedicated resource as the first WUS, and determine whether to perform or not to perform the wake-up operation in the next DRX cycle according to the on / off indication in the WUS, and wake up during the on Duration to listen and receive control information and data information.

[0083] As can be seen from the technical solutions provided in the above embodiments, in the case that the first resource is the dedicated resource corresponding to the sidelink of the first terminal, the first terminal regards the wake-up information received through the first resource as the first wake-up information, and determines whether to perform or not to perform the wake-up operation in the target period of discontinuous reception according to the first wake-up information. Since the dedicated resource is only for one sidelink, even if no additional link information is carried, there will be no misjudgment and confusion, so that the first terminal can reasonably perform the wake-up operation to listen and receive control information and data information, save resources, and achieve the effect of power saving.

[0084] Based on the above embodiments, further, as shown in Figure 4 In the case that the first resource is the shared resource, the method further includes the following steps.

[0085] Step S210, the first terminal acquires the configuration information of the first resource, and the first resource is used for transmitting wake-up information.

[0086] The step S210 can realize the same method embodiment of step S210 in Figure 2 , and obtain the same technical effect, and the repeated parts will not be described here.

[0087] Step S223, according to the first identifier destination L1 ID and / or the second identifier source L1 ID corresponding to the first terminal, the first terminal screens out the first wake-up information corresponding to the first terminal from the wake-up information received from the first resource; wherein the first wake-up information includes the first identifier and / or the second identifier, the first identifier is part or all of the target address destination L2 ID corresponding to the sidelink where the first terminal is located, and the second identifier is part or all of the source address source L2 ID corresponding to the sidelink where the first terminal is located.

[0088] As a SCI, if the WUS is transmitted on the shared resource, it also needs to carry the destination L1 ID and the source L1 ID to indicate the second terminal and the first terminal. In order to save the overhead of SCI as much as possible, all 24-bit L2 IDs will not be carried, but the L1 ID will be obtained by truncating the L2 ID, that is, part of the destination L2 ID is used as the destination L1 ID and / or part of the source L2 ID is used as the source L1 ID.

[0089] The way of obtaining the L1 ID from the L2 ID can be as described above, or a new shorter L1 ID can be used, or a longer L1 ID can be used. The specific truncation is not repeated here. When the first terminal obtains the WUS on the shared resource and uses the truncated L1 ID to determine whether it is the expected first WUS, there is a possibility of false detection and confusion, that is, the truncated destination L1 ID and / or source L1 ID are the same, but the actual destination L2 ID and / or source L2 ID actually correspond to different sidelinks.

[0090] Step S224, determining whether to perform or not to perform the wake-up operation in the target period of discontinuous reception according to the first wake-up information.

[0091] The processing mode of the step S224 can be various. According to different indication modes of the WUS corresponding to the first wake-up information, different processing modes are given in the embodiments of the present application.

[0092] In one embodiment, according to the indication signal contained in the first wake-up information, the first rule is used to determine whether to perform or not to perform the wake-up operation in the target period of discontinuous reception; wherein the indication signal is a first signal for indicating the wake-up operation or a second signal for indicating the non-wake-up operation. For example, 1-bit indication bit is contained in the first wake-up information, and 0 and 1 are used to indicate the non-wake-up operation (off) or the wake-up operation (on) respectively, wherein the non-wake-up operation can also be the sleep operation. In order to be simple, the on or off is used as an example in the following embodiments.

[0093] In one embodiment, the first rule can include:

[0094] In the case of receiving only one first wake-up information, the first terminal determines whether to perform or not to perform the wake-up operation in the target period of discontinuous reception according to the indication signal of the first WUS, i.e. performs the wake-up operation in the case of the indication signal of the first WUS indicating on, wakes up in the on Duration of the next DRX cycle to listen and receive the control information and the data information, and does not perform the wake-up operation in the case of the indication signal of the first WUS indicating off, does not wake up in the on Duration of the next DRX cycle;

[0095] Of course, in the case of receiving only one first WUS, there is also the possibility of false detection:

[0096] Suppose that the second terminal sends the indication signal indicating on in the first WUS, but the first terminal does not receive or receives incorrectly, and the indication signal of the first WUS received by the first terminal in the first resource matches the L1 ID sent by another terminal indicating off, then the first terminal falsely does not perform the wake-up operation and cannot receive the data in the on Duration of the next DRX cycle.

[0097] Further, after the second terminal sends the wake-up information to the first terminal, the second terminal will send the data information to the first terminal in the on Duration of the next DRX cycle;

[0098] If the data information sent by the second terminal is with HARQ feedback, it can judge whether the first terminal correctly performs the wake-up operation by whether the reply message (HARQ feedback) corresponding to the data information is received; in the case of not receiving the reply message corresponding to the data information sent by the first terminal, it is determined that the first terminal may not receive or incorrectly receive the first WUS. At this time, the second terminal can no longer repeatedly send the data information, waits for the next period to send the first wake-up information again, and then sends the data information again. In this way, the data information will not be lost, but an additional period of delay is introduced.

[0099] Assuming that the indication signal contained in the first WUS sent by the second terminal indicates off, but the first terminal does not receive or receives incorrectly, and the indication signal of the first WUS received by the first terminal in the first resource and sent by another terminal matches on, the first terminal has performed the wake-up operation incorrectly, and wakes up in the onDuration of the next DRX cycle to listen and receive control information and data information. At this time, for the second terminal, since it indicates off, the onDuration of the next DRX cycle will not schedule and send data information, which causes a certain resource waste for the first terminal, but no data information loss.

[0100] In another implementation, the first rule can further include:

[0101] In the case of receiving at least two first wake-up information, a third rule is used to determine whether to perform or not to perform the wake-up operation in the target period of discontinuous reception.

[0102] In an implementation, the third rule includes at least one of the following:

[0103] According to a preset rule or a configuration rule, the wake-up operation is performed in the target period of discontinuous reception. The preset rule or the configuration rule can be that all the indication signals contained in the received first WUS are on, and the first terminal wakes up in the onDuration of the next DRX cycle to listen and receive control information and data information; or that one of the indication signals contained in the received first WUS is on, and the first terminal wakes up in the onDuration of the next DRX cycle to listen and receive control information and data information; or that the indication signals contained in the received first WUS are different, and the first terminal wakes up in the onDuration of the next DRX cycle to listen and receive control information and data information.

[0104] According to a preset rule or a configuration rule, the wake-up operation is not performed in the target period of discontinuous reception. The preset rule or the configuration rule can be that all the indication signals contained in the received first WUS are off, and the first terminal does not wake up in the onDuration of the next DRX cycle; or that one of the indication signals contained in the received first WUS is off, and the first terminal does not wake up in the onDuration of the next DRX cycle; or that the indication signals contained in the received first WUS are different, and the first terminal does not wake up in the onDuration of the next DRX cycle.

[0105] According to a larger number of indication signals, it is determined whether to wake up in the on Duration of the next DRX cycle to listen and receive control information and data information. In the case that the number of the first signals is larger than the number of the second signals in the received indication signals, the wake-up operation is performed in the target period of discontinuous reception; in the case that the number of the second signals is larger than the number of the first signals in the received indication signals, the wake-up operation is not performed in the target period of discontinuous reception;

[0106] According to the indication signal of the first WUS received latest, i.e. closer to the start time, it is determined whether to perform or not to perform the wake-up operation in the target period of discontinuous reception;

[0107] According to the indication signal of the first WUS received earliest, i.e. farther from the start time, it is determined whether to perform or not to perform the wake-up operation in the target period of discontinuous reception;

[0108] According to the signal strength, the indication signal of the first WUS with the strongest signal is selected to determine whether to perform or not to perform the wake-up operation in the target period of discontinuous reception.

[0109] In another embodiment, the step S224 can further include that the first terminal determines whether to perform or not to perform the wake-up operation in the target period of discontinuous reception based on the second rule according to whether the first wake-up information is received. For example, it can be determined as indicating on when the first WUS is received, and as indicating off when the first WUS is not received; or it can also be determined as indicating off when the first WUS is received, and as indicating on when the first WUS is not received.

[0110] In another embodiment, for the case that it is determined as indicating on when the first WUS is received, and as indicating off when the first WUS is not received, the second rule can be:

[0111] In the case that the first terminal does not receive the first wake-up information, the wake-up operation is not performed in the target period of discontinuous reception, which is equivalent to that the second terminal and other terminals sending the wake-up message all indicate off, at this time, the first terminal does not wake up in the on Duration of the next DRX cycle;

[0112] In a case where the first terminal receives at least one first wake-up information, the wake-up operation is performed in the target period of discontinuous reception, which is equivalent to that the received first wake-up message is sent by the second terminal or other terminals, at this time, the first terminal wakes up in the next DRX cycle on Duration to listen and receive control information and data information; in this case, even if the second terminal does not send the first wake-up information, the first terminal only wastes part of the resources and does not miss the data information. But in order to reduce the resource waste caused by the false detection as much as possible, the L2 ID configured by different sidelinks can be more easily distinguished according to the service characteristics, only the sparse service has the possibility of L1 ID confusion with each other, and the confusion of sparse service and dense service is avoided.

[0113] In an embodiment, for the case of determining as indicating off when receiving the first WUS, and determining as indicating on when not receiving the first WUS, the second rule can also be:

[0114] In a case where the first terminal does not receive the first wake-up information, the wake-up operation is performed in the target period of discontinuous reception, which is equivalent to that the second terminal and other terminals sending the wake-up message all indicate on, at this time, the first terminal wakes up in the next DRX cycle on Duration to listen and receive control information and data information;

[0115] In a case where the first terminal receives at least one first wake-up information, the wake-up operation is not performed in the target period of discontinuous reception, which is equivalent to that the received first wake-up message is sent by the second terminal or other terminals, at this time, the first terminal does not wake up in the next DRX cycle on Duration; in this case, even if the second terminal does not send the first wake-up information, the first terminal does not perform the wake-up operation due to receiving the first WUS of other terminals, at this time, the second terminal can determine that the first terminal may not perform the wake-up operation by not receiving the reply message corresponding to the data information sent by the first terminal, so as to skip the target period and send the data information in the next period. But in order to reduce the resource waste caused by the false detection as much as possible, the L2 ID configured by different sidelinks can be more easily distinguished according to the service characteristics, only the sparse service has the possibility of L1 ID confusion with each other, and the confusion of sparse service and dense service is avoided.

[0116] From the technical solutions provided in the above embodiments, it can be seen that in the case that the first resource is shared with the shared resource, the first terminal filters out first wake-up information corresponding to the first terminal from the wake-up information received by the first terminal from the first resource according to the first identifier and / or the second identifier corresponding to the first terminal; according to an indication signal contained in the first wake-up information, the first terminal determines whether to perform or not to perform a wake-up operation in a target period of discontinuous reception based on a first rule; the indication signal is a first signal for indicating the performance of the wake-up operation or a second signal for indicating the non-performance of the wake-up operation; according to whether the first wake-up information is received or not, the first terminal determines whether to perform or not to perform the wake-up operation in the target period of discontinuous reception based on a second rule, so that the first terminal can reasonably perform the wake-up operation to control information and data information, save resources, and achieve the effect of power saving.
