[0034] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0035] The V2X communication of the Internet of Vehicles can realize the interconnection and intercommunication between vehicles (V2V), vehicles and roadside infrastructure (V2I), and vehicles and terminals (V2P). Among them, the terminal refers to the pedestrian terminal P-UE in the vehicle to pedestrian (V2P) communication. P-UE is usually a handheld mobile device with low battery capacity and limited wireless capabilities. In the scenario of side road communication, P-UE continuously sends and receives V2X messages, which makes the energy consumption of P-UE high.

[0036] It should be noted that V2X may be implemented through a PC5 interface or a Uu interface, wherein the PC5 interface refers to the air interface of device to device (D2D), and the Uu interface refers to the air interface of the terminal to the base station (such as gNB). In the embodiment of the present application, PC5 and Sidelink have the same meaning, and are both used to represent the air interface link between the P-UE and other UEs.

[0037] In an embodiment of the present application, a method for energy saving is provided, which is applied to a terminal, namely, a P-UE.

[0038] Figure 1A flowchart of an energy saving method provided by an embodiment, such as Figure 1 As shown, the method provided in this embodiment includes step 110 and step 120.

[0039] In step 110, side channel discontinuous reception DRX parameters are obtained, where the side channel DRX parameters are determined according to the location information of the terminal, the side channel communication type and related configuration parameters.

[0040] In this embodiment, the side DRX parameter is the PC5 DRX parameter, which mainly includes the PC5 DRX period, which is used to reflect when the P-UE can stop monitoring the physical side control channel. The side DRX parameter is related to the location information of the terminal, the side communication type and related configuration parameters, wherein the related configuration parameters include parameters configured on the network side and pre-configured parameters.

[0041] In one embodiment, the P-UE may autonomously select the side DRX parameters according to the location information, the side communication type and the related configuration parameters, or the network side may determine the side DRX parameters according to the location information, the side communication type and the related configuration parameters and indicate them to the P-UE.

[0042] In step 120, during the side channel sleep time corresponding to the side channel DRX parameter, no side channel control information SCI of the target device is received.

[0043] In this embodiment, the P-UE or the network side notifies the target device of the side DRX parameters, and the target device will not send data to the P-UE during the sleep time corresponding to the side DRX parameters of the P-UE. Therefore, the P-UE can stop monitoring the physical side control channel during the sleep time according to the side DRX parameters, thereby reducing the energy consumption of the terminal.

[0044] In this embodiment, the P-UE obtains the side DRX parameters and notifies the target device. On this basis, the P-UE can stop monitoring the physical side control channel within a period of time corresponding to the side DRX parameters, thereby reducing the energy consumption of the terminal and saving the power of the terminal.

[0045] In one embodiment, the location information includes one of the following: inside coverage, outside coverage; the side communication type includes one of the following: side unicast communication, side multicast communication, side broadcast communication.

[0046] In this embodiment, NR V2X communication supports unicast, groupcast and broadcast. The transmission of these three types of side communication may be realized within the coverage of the base station, outside the coverage or within partial coverage. NR V2X communication includes mode 1 and mode 2, where mode 1 refers to the PC5 resources configured by the base station (gNB) to transmit V2X services, and mode 2 refers to the PC5 resources independently selected by the UE to transmit V2X services.

[0047] In one embodiment, the side DRX parameter is also determined according to the connection state of the terminal; the connection state includes one of the following: Radio Resource Control (RRC) connected state, RRC idle state, and RRC inactive state.

[0048] Three RRC states of UE are defined in NR: Idle, Inactive, and Connected. In the RRC Idle state, UE context is retained in UE, gNB, and 5GC, and the Non-access stratum (NAS) connection and NG interface connection are retained. Based on the RRC connection recovery process, the RRC Inactive UE needs to enter the Connected state when sending data. The UE needs to be in the RRC Idle state, RRC Inactive state, or Connected state to receive data.

[0049] There are two types of discontinuous reception DRX: one is IDLE discontinuous reception, that is, discontinuous reception when the UE is in IDLE or Inactive state. Since there is no RRC connection and user-specific resources in the RRC idle state or RRC inactive state, it is necessary to monitor the paging channel and the broadcast channel. When the DRX cycle is defined, discontinuous reception can be achieved; the other is ACTIVE discontinuous reception, that is, discontinuous reception when the UE is in the RRC connected state. In this case, the system resource configuration can be optimized, and more importantly, the terminal power can be saved without the terminal entering the RRC idle state or RRC inactive state mode. For example, for some non-real-time applications, such as Web browsing, instant messaging, etc., there is always a period of time, and the terminal does not need to always monitor downlink data and related processing, so discontinuous reception can be adopted. If there is still an RRC connection in the discontinuous reception state, the UE will switch to the active state very quickly.

[0050] In the discontinuous reception mode in the RRC connected state, there are short DRX cycles and long DRX cycles. Usually, the short DRX cycle is entered first. When the DRX short cycle timer (DRX Short Cycle Timer) times out, the long DRX cycle is entered. The longer the DRX cycle, the longer the UE is in sleep, and the more energy is saved. However, the cost is that if a data packet arrives during the sleep period, it is easy to cause packet transmission and reception delays, affecting user experience. During the working time (On Duration), the UE monitors and decodes the Physical Downlink Control Channel (PDCCH). If it finds an uplink (UpLink, UL) or downlink (Down Link, DL) grant scheduling (Grant) for itself, it further reads the content of PDSCH or sends data. Otherwise, the UE enters the sleep state (Sleep) to achieve energy saving. In the RRC idle state DRX, the UE monitors the paging (Paging) paging message every DRX cycle. If it finds a paging message for itself, it further receives downlink data. Otherwise, the UE enters sleep again. In addition, before the RRC idle state UE wakes up from the sleep state to monitor the paging message, the RRC idle state UE usually needs to perform a measurement to perform a cell reselection.

[0051] In one embodiment, the side DRX parameter is notified to the target device by the terminal or the network side.

[0052] In this embodiment, the P-UE or the network side notifies the target device of the side DRX parameters, such as the opposite UE participating in the side unicast communication, or the member terminal in the side multicast group, or other terminals within the broadcast range, so that the target device avoids sending data to the P-UE during the sleep time corresponding to the side DRX parameters of the P-UE. The P-UE stops monitoring the physical side control channel during the sleep time, thereby reducing the energy consumption of the terminal.

[0053] In one embodiment, the side DRX parameters are determined by the network side or selected by the terminal autonomously; when the location information of the terminal is within the coverage, the side DRX parameters are determined by the network side or selected by the terminal autonomously; when the location information of the terminal is outside the coverage, the side DRX parameters are selected by the terminal autonomously.

[0054] In this embodiment, if the terminal is within the coverage of the base station, the terminal can autonomously select the side DRX parameters, or the network side can determine the side DRX parameters and indicate them to the terminal. The terminal can determine how to obtain the side DRX parameters according to the instructions of the network side; if the terminal is outside the coverage of the base station, the terminal autonomously selects the side DRX parameters.

[0055] In one embodiment, the network side includes at least one of the following: a base station, an AMF; wherein the base station indicates the side DRX parameters to the terminal through RRC signaling; and the AMF indicates the side DRX parameters to the terminal through NAS signaling.

[0056] Figure 2 FIG. 1 is a schematic diagram of a side communication provided by an embodiment. Figure 2 As shown in the figure, the V2X network architecture includes the Next Generation Radio Access Network (NG-RAN) base station, such as gNB; the core network (5th Generation Core, 5GC), which at least includes the Access and Mobility Management Function (AMF); and multiple V2X-supporting UEs, one of which is a P-UE. The PC5 air interface is used between the UEs for side communication, and the Uu air interface is used between the UE and the gNB.

[0057] In one embodiment, it further includes:

[0058] Step 130: Determine the side channel working time within the DRX cycle of the terminal according to the side channel DRX parameter;

[0059] Step 140: Start timer T at the beginning of the sideline working time and detect the SCI of the target device; if the SCI of the target device is received before the timer T times out, restart the timer T and continue to detect the SCI; if the SCI of the target device is not received before the timer T times out, enter sideline sleep.

[0060] In this embodiment, the P-UE receives the stage-1SCI on the physical sidelink control channel (PSCCH) and the stage-2SCI on the physical sidelink shared channel (PSSCH) on the PC5 interface during the working time corresponding to the sidelink DRX parameters, as well as the corresponding PSSCH, physical sidelink feedback channel (PFSCH), etc.

[0061] In one embodiment, it further includes:

[0062] Step 150: Determine the side sleep time of the terminal according to the side DRX parameter; during the side sleep time, the terminal supports receiving a semi-persistent scheduling (Semi-Persistent Scheduling, SPS) physical side shared channel PSSCH and a physical side feedback channel PSFCH sent by the target device; the terminal enters the side sleep in one of the following ways: a preset timer T times out, a media access control (Media Access Control, MAC) control unit (Control Unit, CE) command.

[0063] In this embodiment, the side DRX parameters mainly include the PC5 DRX cycle, and the P-UE can determine the side sleep time according to the side DRX parameters. During the sleep time corresponding to the side DRX parameters, no SCI (including stage-1 SCI on PSCCH and stage-2 SCI on PSSCH) is received on the PC5 interface, but PSFCH or SPS PSSCH can be received, and the opposite UE can send PSFCH information or SPS PSSCH data to the P-UE.

[0064] In this embodiment, when the preset timer T times out or when a MAC CE command is received, the terminal stops the timer T and enters the side sleep. For a P-UE in an RRC connected state, the side sleep can be entered by the preset timer T timing out or receiving a MAC CE command; for a P-UE in an RRC idle state or an RRC inactive state, the side sleep can be entered by the preset timer T timing out.

[0065] In one embodiment, unicast or multicast side communication supports hybrid automatic repeat request (HARQ) retransmission, and the length of the DRX retransmission timer can be set according to the delay requirement of the V2X service.

[0066] In one embodiment, the relevant configuration parameters include at least one of the following:

[0067] 1) A first parameter (denoted as para1), which is determined according to the minimum service delay in the side service running on the terminal. The P-UE selects the minimum service delay as para1 from the side service delays of the V2X application running on the P-UE, para1=min(delay buget of APP-1, delay buget of APP-2, ..., delay buget of APP-n);

[0068] 2) The second parameter (denoted as para2), which is configured by the network side. Para2 may further include NG-RAN configuration (denoted as para2.1) and AMF configuration (denoted as para2.2). In some embodiments, para2 may also include hetero-frequency scheduling (denoted as para2.3);

[0069] 3) A pre-configured third parameter (denoted as para3);

[0070] 4) a fourth parameter (denoted as para4), the fourth parameter is indicated by a target device of the unicast side communication (ie, a peer UE in the side unicast communication);

[0071] 5) The fifth parameter (denoted as para5): the fifth parameter is indicated by the Uu port DRX parameter configured on the network side. para5 may further include NG-RAN configuration (denoted as para5.1) and AMF configuration (denoted as para5.2).

[0072] In one embodiment, when the location information is within coverage, the side communication type is side unicast communication, and the connection state is RRC connected state, the relevant configuration parameters include para1, para2 and para4; wherein para2 includes the parameter para2.1 configured by the base station; the side DRX parameter is the minimum value of para1, para2.1 and para4; and the target device includes the opposite terminal of the unicast side communication.

[0073] In this embodiment, for a P-UE in coverage, in RRC connected state, and in side unicast communication, the side DRX parameter is the minimum value para-cu=min(para1, para2.1, para4) among the related configuration parameters.

[0074] In addition, if para-cu is less than para5 configured on the network side, the P-UE requests the base station to modify para5 so that para5 is less than para-cu. If the base station accepts the request of the P-UE, that is, agrees to modify para5 so that para5 is less than para-cu, para-cu is used as the final side DRX, and the P-UE or the network side notifies the opposite UE participating in the side unicast communication of the final side DRX parameter value para-cu, so that the opposite UE avoids sending data to the P-UE during the side sleep time of the P-UE, but the opposite UE can send PSFCH information or SPS PSSCH data to the P-UE; if the base station rejects the request of the P-UE, the current side DRX function (or para-cu) is invalid, and the P-UE can request the base station to modify para5 again after a period of time (such as after a certain timer T times out); if the number of requests exceeds the threshold value, the side DRX function (or para-cu) is invalid within the coverage of the current base station.

[0075] In one embodiment, when the location information is within coverage, the side communication type is side multicast communication or side broadcast communication, and the connection state is RRC connected state, the relevant configuration parameters include para1 and para2; wherein para2 includes the parameter para2.1 configured by the base station; the side DRX parameter is the minimum value of para1 and para2; and the target device includes a multicast group member terminal or a terminal in the broadcast range.

[0076] In this embodiment, for a P-UE in coverage, in RRC connected state, in side multicast communication or side broadcast communication, the side DRX parameter is the minimum value para-cg / b=min(para1, para2.1) among the relevant configuration parameters.

[0077] In addition, if para-cg / b is less than para5 configured on the network side, the P-UE may request the base station to modify para5 so that para5 is less than para-cg / b; if the base station accepts the request of the P-UE, that is, agrees to modify para5 so that para5 is less than para-cg / b, then para-cg / b is used as the final side DRX, and the P-UE or the network side notifies the target device, such as the multicast group member or other UEs within the broadcast range, of the final side DRX parameter, so that the related UEs of the multicast or broadcast avoid sending data to the P-UE during the side sleep time of the P-UE, but can send PSFCH information or SPS PSSCH data to the P-UE; if the base station rejects the request of the P-UE, the current side DRX function (or para-cg / b) is invalid, and the P-UE may request the base station to modify para5 again after a period of time (such as after a certain timer T times out); if the number of requests exceeds the threshold, the side DRX function (or para-cg / b) is invalid within the coverage of the current base station.

[0079] In this embodiment, for a P-UE in coverage, in RRC idle state or RRC inactive state, and in side unicast communication, the side DRX parameter is the minimum value para-i / au=min(para1, para2, para4) among the relevant configuration parameters.

[0080] In addition, if para-i / au is less than para5 configured on the network side, the P-UE may first enter the RRC connected state, and then request the base station to modify para5 so that para5 is less than para-i / au; if the base station accepts the request of the P-UE, that is, agrees to modify para5 so that para5 is less than para-i / au, then para-i / au is used as the final side DRX, and the P-UE or the network side notifies the target device, that is, the opposite end UE of the unicast side communication, of the final side DRX parameter, so that the opposite end UE avoids sending data to the P-UE during the side sleep time of the P-UE, but can send PSFCH information or SPS PSSCH data to the P-UE; if the base station rejects the request of the P-UE, the current side DRX function (or para-i / au) is invalid, and the P-UE may request the base station to modify para5 again after a period of time (such as after a certain timer T times out); if the number of requests exceeds the threshold value, the side DRX function (or para-i / au) is invalid within the coverage of the current base station.

[0081] In one embodiment, when the location information is within coverage, the side communication type is side multicast communication or side broadcast communication, and the connection state is RRC idle state or RRC inactive state, the relevant configuration parameters include para1 and para2; the side DRX parameter is the minimum value of para1 and para2; the target device includes a multicast group member terminal or a terminal in the broadcast range.

[0082] In this embodiment, for P-UE within coverage, in RRC idle state or RRC inactive state, in side multicast communication or side broadcast communication, the side DRX parameter is the minimum value para-i / ag / b=min(para1, para2) among the relevant configuration parameters.

[0083] In addition, if para-i / ag / b is less than para5 configured on the network side, the P-UE may first enter the RRC connected state, and then request the base station to modify para5 so that para5 is less than para-i / ag / b; if the base station accepts the request of the P-UE, that is, agrees to modify para5 so that para5 is less than para-i / ag / b, then para-i / ag / b is used as the final side DRX, and the P-UE or the network side notifies the target device of the final side DRX parameter, so that the related UEs of multicast or broadcast avoid sending data to the P-UE during the side sleep time of the P-UE, but can send PSFCH information or SPS PSSCH data to the P-UE; if the base station rejects the request of the P-UE, the current side DRX function (or para-i / ag / b) is invalid, and the P-UE can request the base station to modify para5 again after a period of time (such as after a certain timer T times out); if the number of requests exceeds the threshold, the side DRX function (or para-i / ag / b) is invalid within the coverage of the current base station.

[0084] In one embodiment, para2 includes: parameter para2.1 configured by the base station and parameter para2.2 configured by the AMF; or, para2 includes: parameter para2.1 configured by the base station, parameter para2.2 configured by the AMF, and parameter para2.3 of side channel heterogeneous frequency scheduling configured by the base station.

[0085] In this embodiment, for the case where the location information is within coverage and the connection state is RRC idle state or RRC inactive state, para2 includes para2.1 and para2.2. Alternatively, prar2 may include para2.3 in addition to para2.1 and para2.2.

[0086] Correspondingly, for a P-UE whose side communication type is side unicast communication, the side DRX parameter is para-i / au=min(para1, para2.1, para2.2, para4), or para-i / au=min(para1, para2.1, para2.2, para2.3, para4).

[0087] For a P-UE whose side communication type is side multicast communication or side broadcast communication, the side DRX parameters are para-i / ag / b=min(para1, para2.1, para2.2), or para-i / ag / b=min(para1, para2.1, para2.2, para2.3).

[0088] In one embodiment, when the location information is out of coverage and the side communication type is side unicast communication, the relevant configuration parameters include a first parameter, a third parameter and a fourth parameter; the side DRX parameter is the minimum value of the relevant configuration parameters; and the target device includes a terminal for unicast side communication.

[0089] In this embodiment, for the P-UE with out-of-coverage and side unicast communication, the side DRX parameter is the minimum value para-ou=min(para1, para3, para4) among the relevant configuration parameters, and para-ou is used as the finally determined side DRX parameter. The P-UE can notify the terminal of the unicast side communication of para-ou.

[0090] In one embodiment, when the location information is out of coverage and the side communication type is side multicast communication or side broadcast communication, the relevant configuration parameters include a first parameter and a third parameter; the side DRX parameter is the minimum value among the relevant configuration parameters; and the target device includes a multicast member terminal or a terminal in the broadcast range.

[0091] In this embodiment, for the P-UE in coverage outside, side multicast communication or side broadcast communication, the side DRX parameter is the minimum value para-og / b=min(para1, para3) among the relevant configuration parameters, and para-og / b is used as the final side DRX parameter. The P-UE can notify the multicast member terminals or the terminals in the broadcast range of para-ou.

[0092] In one embodiment, the relevant configuration parameters also include a second parameter; the second parameter includes a parameter of side channel heterodyne scheduling configured by the base station.

[0093] In this embodiment, for the case where the location information is out of coverage, the relevant configuration parameters may further include para2, and prar2 includes the parameter para2.3 of the side channel heterodyne scheduling configured by the base station.

[0094] Correspondingly, for a P-UE whose side communication type is side unicast communication, the side DRX parameter is para-ou=min(para1, para2.3, para3, para4). For a P-UE whose side communication type is side multicast communication or side broadcast communication, para-ou=min(para1, para2.3, para3).

[0095] In one embodiment, the relevant configuration parameters also include: a fifth parameter, the fifth parameter includes the Uu port DRX parameter configured on the network side; the method also includes: step 160: when the side DRX parameter is less than the fifth parameter, request the network side to modify the fifth parameter so that the side DRX parameter is an integer multiple of the fifth parameter.

[0096] This embodiment is applicable to P-UE in coverage and RRC connected state, and the side communication type of P-UE can be side unicast communication, side multicast communication or side broadcast communication. P-UE can send a request to the base station, requesting the base station to modify para5 (UuDRX parameters, including Uu DRX cycle) so that the side DRX parameters and Uu DRX parameters match each other, that is, the side DRX parameters are integer multiples of the Uu DRX parameters, that is, parameters of PC5 DRX=N*(parameters of Uu DRX), where N=1,2,...,Nmax, and the product of Nmax and the period of Uu DRX does not exceed the minimum delay of V2X service, where Uu DRX period refers to the default Uu DRX period, such as the Uu DRX period of system message broadcast, or the P-UE dedicated Uu DRX period set by the base station through RRC signaling.

[0097] In one embodiment, it further includes:

[0098] Step 170: When the network side refuses to modify the fifth parameter, resend the request according to the timer information; when the number of times the request is sent exceeds the preset threshold, the side DRX parameter is invalid.

[0099] In this embodiment, after receiving the request from the P-UE, the base station sends a response message to the P-UE to indicate whether to modify the UuDRX parameters. If the modification of the Uu DRX parameters is refused, the side DRX parameter configuration obtained by the P-UE is invalid. The P-UE can renegotiate the side DRX parameters with the network side to make the side DRX parameters match the Uu DRX parameters; or, after a period of time (such as the set timer times out), the P-UE again requests the base station to modify the Uu DRX parameters; if the number of requests exceeds the preset threshold, the P-UE cannot perform side discontinuous reception with the target device.

[0100] In one embodiment, the relevant configuration parameters further include: a fifth parameter, the fifth parameter includes a Uu port DRX parameter configured by the network side; and the method further includes:

[0101] Step 180: When the side DRX parameter is less than the Uu port DRX parameter, enter the connected state and request the network side to modify the fifth parameter so that the side DRX parameter is an integer multiple of the fifth parameter.

[0102] This embodiment is applicable to P-UE within coverage, in RRC idle state or RRC inactive state, and the side communication type of P-UE can be side unicast communication, side multicast communication or side broadcast communication. P-UE first determines the side DRX parameter according to the minimum delay of V2X service, and the PC5 DRX cycle corresponding to the side DRX parameter does not exceed the minimum delay of V2X service; then, P-UE compares the above side DRX parameter with the default Uu DRX cycle broadcasted by the system message, and if the PC5 DRX cycle is not less than the Uu DRX cycle, the side DRX parameter can be used; if the PC5 DRX cycle is less than the Uu DRX cycle, the P-UE re-determines the side DRX parameter, and the side DRX parameter should be greater than or equal to the Uu DRX cycle and less than or equal to the minimum delay of V2X service. If the above relationship cannot be satisfied, the P-UE enters the RRC connected state and sends a request message to the base station, requesting the base station to modify the Uu DRX cycle.

[0103] In one embodiment, it further includes:

[0104] Step 111: When the connection state is the RRC idle state, the fifth parameter (i.e., Uu DRX parameter) is negotiated with the AMF using NAS signaling;

[0105] Step 112: When the connection state is the RRC inactive state, negotiate the fifth parameter (ie, the Uu DRX parameter) with at least one of the base station and the AMF.

[0106] In one embodiment, it further includes:

[0107] Step 100: When a cell on a frequency capable of providing side channel communication is scanned and the cell meets a cell selection criterion, determine that the location information is within coverage; otherwise, determine that the location information is outside coverage.

[0108] In this embodiment, the P-UE determines whether it is in NR coverage by the following method: if the P-UE scans a cell on a frequency that can provide NR side communication, and the cell meets the S criterion (cell selection criterion), it is determined that the P-UE is in NR coverage, otherwise it is determined that the P-UE is outside NR coverage. The above scanning can be within the partial bandwidth (BandWidthPart, BWP) activated by V2X communication, or within the entire V2X frequency band.

[0109] In one embodiment, it further includes:

[0110] Step 101: When the location information is within coverage, convert the direct frame number (DFN) of the Global Navigation Satellite System (GNSS) into a system frame number (SFN) according to a system message.

[0111] In this embodiment, the side DRX and Uu DRX use the same SFN within the coverage, that is, the P-UE uses the base station time as a reference. If the P-UE uses the DFN of the GNSS as a reference, it is necessary to convert the DFN into the SFN according to the system message. Outside the coverage, the UEs participating in the V2X communication are required to use the same time reference, such as all using the DFN of the GNSS, or a certain UE as the time reference, to ensure that the side DRX settings of different UEs are aligned in time.

[0112] Figure 3 FIG. 1 is a schematic diagram of determining a side channel DRX parameter provided by an embodiment. Figure 3 As shown, the process of determining the side channel DRX parameters is as follows:

[0113] 1) For P-UE, first determine whether it is in NR coverage. If so, go to 2) to further determine whether it is in RRC connected state; if not, go to 8) to determine the corresponding side DRX parameters outside the coverage.

[0114] 2) Determine whether the P-UE is in RRC connected state. If so, go to 3) to further determine whether it is side unicast communication; if not, go to 7) to determine the side DRX parameters of the RRC idle state or RRC inactive state.

[0115] Among them, if the P-UE has established an RRC connection with the base station, that is, the P-UE has established uplink synchronization with the base station and the P-UE can send information to the base station, then the P-UE is determined to be in the RRC connected state, otherwise the P-UE is in the RRC idle state or the RRC inactive state.

[0116] 3) Determine whether the P-UE is in side unicast communication, if so, go to 4); if not, go to 6) to determine the side DRX parameters of the side multicast communication or the side broadcast communication.

[0117] If the P-UE establishes a side RRC connection with the other end of the side communication, it is determined that the P-UR is a side unicast communication; otherwise, it is a broadcast or multicast communication.

[0118] 4) The P-UE and the peer UE of the side unicast communication negotiate to determine the side DRX parameters.

[0119] In this case, the side communication type of the P-UE is side unicast communication. The P-UE negotiates the side DRX parameters with the peer UE. Multiple V2X applications can run on the P-UE. Different V2X applications have different DRX requirements. The PC5 DRX period corresponding to the side DRX parameters selected by the P-UE does not exceed the minimum delay Tapp-min in the V2X application. If the PC5 DRX period corresponding to the side DRX parameters given by the P-UE is T1, and the PC5 DRX period given by the peer UE is T2, then the final PC5 DRX period should be T=min(T1, T2), that is, the minimum period value is selected as the final PC5 DRX period. The side DRX parameters other than the PC5 DRX period, such as the values ​​of various DRX-related timers, are determined according to the same principle, that is, the smaller value of the two is selected as the final PC5 DRX parameter value, so as to meet the delay requirements of different V2X applications.

[0120] 5) Determine whether the side DRX parameter is less than the fifth parameter configured on the network side. If so, go to 6), the P-UE sends a request to the base station to request the base station to modify the fifth parameter; if not, go to 10), notify the target device of the side DRX parameter.

[0121] Among them, the P-UE is in the RRC connected state, and the P-UE reads the Uu DRX parameters configured by the base station. If the side DRX parameters of the P-UE do not match the Uu DRX parameters, for example, the PC5 DRX cycle corresponding to the side DRX parameters is smaller than the Uu DRX cycle, in this case, the P-UE in the coverage needs to adopt the V2X communication parameters configured by the base station. If the side is awakened from DRX to monitor PSCCH, the Uu interface is still in the DRX sleep state, then the P-UE cannot obtain the V2X communication parameters, which will cause V2X communication failure. In this case, the P-UE sends indication information to the base station, such as requesting the gNB to modify the Uu DRX parameters so that the side DRX and Uu DRX parameters match each other.

[0122] 6) The P-UE sends a request to the base station to request the base station to modify the fifth parameter;

[0123] 7) The P-UE determines the PC5 DRX parameters of the RRC connected state;

[0124] If the P-UE is a side multicast communication or a side broadcast communication, and the P-UE is the source node of the side multicast communication or the side broadcast communication, the P-UE determines the side DRX parameters according to the minimum delay requirement of the V2X service, and the PC5 DRX cycle does not exceed the minimum delay of the V2X service. In addition, if the side DRX parameters of the P-UE do not match the Uu DRX parameters, the P-UE can send indication information to the base station, such as requesting the gNB to modify the Uu DRX parameters so that the side DRX and Uu DRX parameters match each other.

[0125] The P-UE or the network side can send the finalized side DRX parameters to the multicast members in the multicast group of the PC5 interface, or broadcast them to other nearby UEs participating in the PC5 broadcast. If the P-UE is a V2X multicast member or broadcast receiver, the P-UE can also notify other UEs of the determined PC5 DRX parameters.

[0126] 8) The P-UE determines the side DRX parameters in the RRC idle state or the RRC inactive state, including the PC5 DRX cycle;

[0127] The P-UE first determines the side DRX parameters according to the minimum delay of the V2X service, and the PC5 DRX cycle should meet the requirement of not exceeding the minimum delay of the V2X service; then, the P-UE compares the above PC5 DRX cycle with the default Uu DRX cycle broadcast by the system message. If the PC5 DRX cycle is not less than the Uu DRX cycle, the side DRX parameters are adopted; if the PC5 DRX cycle is less than the Uu DRX cycle, the P-UE resets the side DRX parameters, and it should meet the requirement that the PC5 DRX cycle is greater than or equal to the Uu DRX cycle, and the PC5 DRX cycle is less than or equal to the minimum delay of the V2X service. If the above relationship cannot be met, the P-UE enters the RRC connected state and sends a request message to the base station, requesting the base station to modify the Uu DRX cycle.

[0128] The PC5DRX period corresponding to the side DRX parameters of the P-UE in RRC idle state or RRC inactive state on the PC5 interface is set to an integer multiple of the Uu DRX period of the P-UE on the Uu interface: Periodicity of PC5-DRX = N*(Periodicityof Uu-DRX), N = 1, 2, ..., Nmax, where Nmax is a positive integer and the product of Nmax and the Uu DRX period is less than the minimum delay of the V2X message.

[0129] 9) The P-UE determines the DRX parameters of the out-of-coverage side channels.

[0130] If the P-UE is outside the NR coverage, the P-UE can use the pre-configured PC5 DRX cycle stored in itself, or use the PC5 DRX cycle of the inter-frequency V2X communication broadcast in the current cell; if the cell where the P-UE currently resides broadcasts the PC5 DRX cycle of the inter-frequency V2X communication, the P-UE cannot use the pre-configured PC5 DRX cycle, but can only use the PC5 DRX cycle of the inter-frequency V2X communication broadcast by the cell; if there is neither a pre-configured PC5 DRX cycle nor a PC5 DRX cycle of the inter-frequency V2X communication broadcast by the cell, the P-UE can independently configure the side DRX parameters to ensure that the PC5 DRX cycle does not exceed the minimum delay of the V2X service.

[0131] 10) The P-UE or the network side notifies the target device of the determined side DRX parameters, such as the peer UE in the side unicast communication, or the group member in the side multicast communication, or other UEs participating in the broadcast communication in the side broadcast communication, so that the target device can send V2X information to the P-UE at an appropriate time (such as the working time corresponding to the side DRX parameters). It should be noted that the transmission of PSFCH information and SPS PSSCH is not affected.

[0132] The embodiment of the present application also provides a parameter configuration method, which is applied to a base station, such as a gNB. The operations performed by the base station in this embodiment correspond to the operations performed by the above-mentioned terminal. For technical details not described in detail in this embodiment, refer to any of the above-mentioned embodiments.

[0133] Figure 4 A flow chart of a parameter configuration method provided by an embodiment, such as Figure 4 As shown, the method provided in this embodiment includes step 210 and step 220.

[0134] In step 210, relevant configuration parameters are configured, where the relevant configuration parameters are used to instruct the terminal to obtain side channel DRX parameters.

[0135] In this embodiment, the side DRX parameter is a PC5 DRX parameter, which mainly includes a PC5 DRX cycle, and is used to reflect when the P-UE can stop monitoring the physical side control channel.

[0136] In step 220, the relevant configuration parameters are sent to the terminals whose location information is within the coverage.

[0137] In this embodiment, the terminal within the coverage can determine the side DRX parameters based on one or more of the location information, the side communication type, the pre-configured related configuration parameters, and the related configuration parameters configured by the base station, or the base station determines the side DRX parameters based on the location information, the side communication type and the related configuration parameters and indicates them to the P-UE; and the terminal outside the coverage can determine the side DRX parameters based on the location information, the side communication type, and one or more of the pre-configured related configuration parameters.

[0138] The parameter configuration method of this embodiment configures relevant configuration parameters to allow the terminals within the coverage to determine the side DRX parameters. On this basis, the terminals can stop monitoring the physical side control channel for a period of time, thereby reducing the energy consumption of the terminals.

[0142] The fifth parameter para5 is modified according to the request so that the side DRX parameter is an integer multiple of the fifth parameter (para5).

[0143] In this embodiment, after receiving the request from the P-UE, the base station may also send a response message to the P-UE to indicate whether to modify the Uu DRX parameters. If the modification of the Uu DRX parameters is rejected, the side DRX parameter configuration determined by the P-UE is invalid, and the P-UE may renegotiate the side DRX parameters with the network side to make the side DRX parameters match the Uu DRX parameters; or, after a period of time (such as the set timer expires), the P-UE again requests the base station to modify the Uu DRX parameters; if the base station rejects the request more than a certain number of times, the side DRX parameters are invalid, and the P-UE cannot perform side discontinuous reception with the target device.
