技术领域Technical field

本申请实施例涉及通信技术领域，尤其涉及一种处理侧行链路资源的方法、装置及系统。The embodiments of the present application relate to the field of communication technologies, and in particular, to a method, device, and system for processing side link resources.

背景技术Background technique

在长期演进(long time evolution，LTE)系统或新空口(new radio，NR)系统中，终端之间的通信接口可以称为PC5接口。PC5接口一般用于车辆对一切(vehicle-to-everything，V2X)，或者D2D等可以在设备间进行直联通信的场景。在PC5接口上，TX终端可以通过侧行链路(sidelink，SL)向RX终端传输侧行链路数据。为了保证侧行链路数据传输的可靠性，RX终端可以向TX终端发送混合自动重复请求(hybrid autonomous repeat request，HARQ)进程对应的HARQ信息。该HARQ信息用于指示侧行链路数据是否被RX终端正确接收。In a long-time evolution (LTE) system or a new radio (NR) system, the communication interface between terminals may be called a PC5 interface. The PC5 interface is generally used in scenarios where vehicle-to-everything (V2X) or D2D can directly communicate between devices. On the PC5 interface, the TX terminal can transmit sidelink data to the RX terminal through the sidelink (SL). In order to ensure the reliability of sidelink data transmission, the RX terminal may send HARQ information corresponding to the hybrid automatic repeat request (HARQ) process to the TX terminal. The HARQ information is used to indicate whether the side link data is correctly received by the RX terminal.

TX终端在接收到HARQ信息之后，可以向网络设备发送该HARQ信息，以使得网络设备根据HARQ信息确定侧行链路数据未被正确接收时，为TX终端重新分配用于重新传输侧行链路数据的侧行链路资源。在网络设备根据HARQ信息确定侧行链路数据被正确接收的情况下，网络设备为TX终端分配用于传输其他侧行链路数据的侧行链路资源。After the TX terminal receives the HARQ information, it can send the HARQ information to the network device, so that when the network device determines that the side link data is not received correctly according to the HARQ information, the TX terminal is re-allocated for retransmission of the side link Data side link resources. In the case that the network device determines that the side link data is correctly received according to the HARQ information, the network device allocates the side link resources for transmitting other side link data to the TX terminal.

但是，TX终端可能无法向网络设备发送该HARQ信息，或者网络设备无法接收到HARQ信息，对于这种情况，现有技术中未描述TX终端如何处理后续的HARQ过程。However, the TX terminal may not be able to send the HARQ information to the network device, or the network device may not be able to receive the HARQ information. In this case, how the TX terminal processes the subsequent HARQ process is not described in the prior art.

本申请实施例提供一种处理侧行链路资源的方法，该方法中第一终端可以在确定在第一时刻未向网络设备发送确认信息，以及该确认信息指示第二终端正确接收第一数据包的情况下，如果第一终端又接收到第二侧行链路资源。由于第二侧行链路资源的HARQ参数包括NDI指示。NDI指示通常用于指示重传或者新传，当发生该情况时，第一终端可以根据HARQ参数，处理该第二侧行链路资源。由于第一数据包被第二终端正确接收，因此，第一终端不需要对第一数据包进行重传，通过对第二侧行链路资源作处理可以避免第一终端的不必要的传输，以及避免第二终端不必要的反馈。The embodiment of the present application provides a method for processing side link resources. In the method, the first terminal may determine that no confirmation information is sent to the network device at the first moment, and the confirmation information indicates that the second terminal correctly receives the first data In the case of packets, if the first terminal receives the second side uplink resource again.

When this happens, the first terminal can process the second side uplink resource according to the HARQ parameters. Since the first data packet is correctly received by the second terminal, the first terminal does not need to retransmit the first data packet, and unnecessary transmission by the first terminal can be avoided by processing the second side uplink resources. And to avoid unnecessary feedback from the second terminal.

如图1所示，图1示出了本申请实施例提供的一种场景，如图1所示，以第一终端20为标识为X的车辆(简称：车辆X)为例，如果车辆X决定执行超车操作，则车辆X可以向位于其前方的第二终端30(例如，标识为Y的车辆(简称：车辆Y))在第一侧行链路资源上发送对话框50的中的第一数据包(例如，第一数据包可以为超车指示、车辆X的当前车速(例如，75km/h))，以便车辆Y接收到X的当前车速以及超车指示后，减速行驶，以使得X安全超车。如果车辆Y接收到X的当前车速以及超车指示，则车辆Y可以向车辆X反馈对话框60的信息。车辆X接收到车辆Y的信息后，确定车辆Y正确接收超车指示、车辆X的当前车速后，则可以向网络设备10反馈ACK作为确认信息，以便网络设备10确定在第一侧行链路资源上向车辆Y发送的超车指示、车辆X的当前车速已被车辆Y正确接收。但是由于车辆X向网络设备10反馈ACK的时刻有可能和车辆X发送的随机接入消息冲突，因此，车辆X会优先向网络设备10发送随机接入消息，而放弃向网络设备10反馈ACK。As shown in Fig. 1, Fig. 1 shows a scenario provided by an embodiment of the present application. As shown in Fig. 1, taking the first terminal 20 as the vehicle with the identification X (abbreviated as: vehicle X) as an example, if the vehicle X Deciding to perform an overtaking operation, vehicle X can send the second terminal 30 in front of it (for example, the vehicle identified as Y (abbreviated as vehicle Y)) on the first sidelink resource in the dialog box 50. A data packet (for example, the first data packet may be an overtaking instruction, the current speed of vehicle X (for example, 75km/h)), so that vehicle Y will slow down after receiving X's current speed and overtaking instruction to make X safe overtake. If the vehicle Y receives the current speed of X and the overtaking instruction, the vehicle Y can feed back the information of the dialog box 60 to the vehicle X. After vehicle X receives the information of vehicle Y and determines that vehicle Y correctly receives the overtaking instruction and the current speed of vehicle X, it can feed back ACK to the network device 10 as confirmation information, so that the network device 10 can determine the first side uplink resource The overtaking instruction sent to vehicle Y and the current speed of vehicle X have been correctly received by vehicle Y. However, since the time when the vehicle X feeds back the ACK to the network device 10 may conflict with the random access message sent by the vehicle X, the vehicle X will preferentially send the random access message to the network device 10 and give up feeding back the ACK to the network device 10.

图1所示的场景仅为举例，其他终端之间通信的场景也适用于本申请方案。The scenario shown in FIG. 1 is only an example, and other scenarios of communication between terminals are also applicable to the solution of this application.

One is the resource allocation method based on the scheduling of the network device 10, that is, the network device 10 schedules the sidelink resources for the first terminal 20. The first terminal 20 may transmit sidelink data or sidelink information to the second terminal 30 on the sidelink resource. The other is the way in which the first terminal 20 autonomously selects resources in the resource pool, that is, the first terminal 20 autonomously selects sidelink resources from the resource pool configured or pre-configured by the network device 10 through system messages or dedicated signaling to The sidelink data or sidelink information is transmitted to the second terminal 30 on the independently selected sidelink resource.

如图3b所示，Uu链路上的下行数据传输的HARQ的基本过程：1、网络设备10向第一终端20发送下行数据。2、第一终端20收到该下行数据后，如果解码失败，第一终端20反馈NACK给网络设备10。3、网络设备10接收到NACK会重传下行数据。使得第一终端20根据重传指示在新的物理下行共享信道(physical downlink shared channel，PDSCH)上重新接收下行数据。网络设备10执行下行数据的重传。4、第一终端20收到该下行数据后，解码成功，则向网络设备10反馈ACK。As shown in FIG. 3b, the basic process of HARQ for downlink data transmission on the Uu link: 1. The network device 10 sends downlink data to the first terminal 20. 2. After the first terminal 20 receives the downlink data, if the decoding fails, the first terminal 20 feeds back a NACK to the network device 10. 3. The network device 10 retransmits the downlink data after receiving the NACK. This allows the first terminal 20 to re-receive downlink data on a new physical downlink shared channel (PDSCH) according to the retransmission instruction. The network device 10 performs retransmission of downlink data. 4. After receiving the downlink data, the first terminal 20 succeeds in decoding, and then feeds back an ACK to the network device 10.

网络设备10执行下行数据的重传，包括：网络设备10通过PDCCH指示PDSCH的资源位置，PDSCH携带重传的下行数据。The network device 10 performing the retransmission of downlink data includes: the network device 10 indicates the resource location of the PDSCH through the PDCCH, and the PDSCH carries the retransmitted downlink data.

目前在LTE系统中，侧行链路数据传输的HARQ基本过程如图3c所示：1、第一终端20发送侧行链路数据(包括数据的新传和重传)给第二终端30。2、第二终端30对侧行链路数据进行解码。由于目前LTE系统中，第一终端20发送侧行链路数据采用广播方式，因此，第二终端30无论是否成功解码侧行链路数据，第二终端30均未向第一终端20发送ACK/NACK反馈。由于第一终端20未接收到第二终端30反馈的ACK，其有可能误以为第二终端30未成功解码，后续过程中还可能如步骤2～M继续向第二终端30重传侧行链路数据，但是由于第二终端30已成功解码侧行链路数据，因此，第二终端30对于重传的侧行链路数据不再解码。这样会使得第一终端20重复 发送侧行链路数据，造成侧行链路资源浪费。In the current LTE system, the basic HARQ process of side-link data transmission is shown in FIG. 3c: 1. The first terminal 20 sends side-link data (including new transmission and retransmission of data) to the second terminal 30. 2. The second terminal 30 decodes the side link data. Since in the current LTE system, the first terminal 20 transmits the side uplink data in a broadcast mode, no matter whether the second terminal 30 successfully decodes the side uplink data or not, the second terminal 30 does not send ACK/ to the first terminal 20. NACK feedback. Since the first terminal 20 does not receive the ACK fed back by the second terminal 30, it may mistakenly believe that the second terminal 30 has not successfully decoded it. In the subsequent process, it may continue to retransmit the side chain to the second terminal 30 as in steps 2 to M. However, since the second terminal 30 has successfully decoded the side uplink data, the second terminal 30 no longer decodes the retransmitted side uplink data. This will cause the first terminal 20 to repeatedly send side-link data, resulting in waste of side-link resources.

在NR系统中，Sidelink支持单播，组播和广播传输。对于单播和组播传输，支持基于HARQ反馈的重传机制。基于网络设备10调度的资源分配方式下，侧行链路数据传输的HARQ过程如图3d所示：In the NR system, Sidelink supports unicast, multicast and broadcast transmission. For unicast and multicast transmission, a retransmission mechanism based on HARQ feedback is supported. Based on the resource allocation mode scheduled by the network device 10, the HARQ process of side link data transmission is shown in Figure 3d:

1、网络设备10向第一终端20发送PDCCH，以调度第一终端20的侧行链路数据的新传。2、第一终端20向第二终端30发送侧行链路数据。3、第二终端30接收到侧行链路数据后，如果解码失败，第二终端30向第一终端20反馈NACK。4、第一终端20反馈NACK给网络设备10。5、网络设备10向第一终端20发送PDCCH，调度第一终端20重新向第二终端30发送第二终端30未成功解码的侧行链路数据，即侧行链路数据重传。6、第一终端20执行侧行链路重传。1. The network device 10 sends a PDCCH to the first terminal 20 to schedule the new transmission of side link data of the first terminal 20. 2. The first terminal 20 sends side link data to the second terminal 30. 3. After the second terminal 30 receives the side link data, if the decoding fails, the second terminal 30 feeds back a NACK to the first terminal 20. 4. The first terminal 20 feeds back a NACK to the network device 10. 5. The network device 10 sends a PDCCH to the first terminal 20, and schedules the first terminal 20 to re-send to the second terminal 30 the side link that the second terminal 30 has not successfully decoded Data, that is, retransmission of side link data. 6. The first terminal 20 performs side-link retransmission.

但是，第一终端20可能未接收到第二终端30反馈的确认信息，这时，第一终端20可能不确定第二终端30是否正确接收到侧行链路数据。进而第一终端20不确定后续如何处理该侧行链路数据。However, the first terminal 20 may not receive the confirmation information fed back by the second terminal 30. At this time, the first terminal 20 may not be sure whether the second terminal 30 correctly receives the side link data. Furthermore, the first terminal 20 is not sure how to process the side link data subsequently.

但是，如图1所示，第一终端20在需要通过反馈Sidelink数据传输的确认信息ACK/NACK给网络设备10时，可能会出现与其它传输的在时间上的冲突或者重叠。例如，第一终端20发送ACK/NACK给网络设备10的时间与第一终端20向网络设备10发送的第一消息或者第一终端20向第二终端30发送的第一消息的时刻相同，因此可以称之为冲突。如果发生冲突时，第一终端20可能会丢弃向网络设备10发送ACK/NACK，这样网络设备10将无法接收到来自第一终端20的ACK/NACK，因此网络设备10可能无法得知第一终端20向第二终端30发送的侧行链路数据是否被正确接收。如果网络设备10未为第一终端20配置重传的侧行链路资源，则未被正确接收到的侧行链路数据可能无法重传。或者如果网络设备10在不知道第一终端20向第二终端30发送的侧行链路数据是否被正确接收的情况下，盲目为第一终端20重新分配了用于重传的侧行链路资源，但是侧行链路数据又被第二终端30正确接收，则在这种情况下，第一终端20如何处理用于重传的侧行链路资源是需要解决的问题。However, as shown in FIG. 1, when the first terminal 20 needs to feed back the sidelink data transmission confirmation information ACK/NACK to the network device 10, there may be a time conflict or overlap with other transmissions. For example, the time when the first terminal 20 sends the ACK/NACK to the network device 10 is the same as the time when the first message sent by the first terminal 20 to the network device 10 or the first message sent by the first terminal 20 to the second terminal 30, so It can be called a conflict. If a conflict occurs, the first terminal 20 may abandon sending ACK/NACK to the network device 10, so that the network device 10 will not be able to receive the ACK/NACK from the first terminal 20, so the network device 10 may not know the first terminal 20 Whether the side link data sent to the second terminal 30 is received correctly. If the network device 10 does not configure the side link resource for retransmission for the first terminal 20, the side link data that is not received correctly may not be retransmitted. Or if the network device 10 blindly reassigns the side link for retransmission for the first terminal 20 without knowing whether the side link data sent by the first terminal 20 to the second terminal 30 is received correctly Resources, but the side link data is correctly received by the second terminal 30. In this case, how the first terminal 20 handles the side link resources for retransmission is a problem to be solved.

基于此，本申请实施例中第一终端20可以在确定在第一时刻20未向网络设备10发送确认信息，以及该确认信息指示第二终端30正确接收第一数据包的情况下，如果第一终端20又接收到用于重传第一侧行链路HARQ进程的第一数据包的第二侧行链路资源，以及新数据重传(new data indicator，NDI)。由于NDI指示通常用于指示重传或者新传，当发生该情况时，第一终端20可以根据第一HARQ进行的信息，处理该第二侧行链路资源。由于第一数据包被第二终端30正确接收，因此，第一终端20不需要在第二侧行链路资源上对第一数据包重传，第一终端通过忽视第二侧行链路资源或者传输除第一数据包以外的其他数据包(例如，第二数据包)可以避免第一终端20的不必要的传输，以及避免第二终端30不必要的反馈。Based on this, in the embodiment of the present application, the first terminal 20 can determine that the confirmation information is not sent to the network device 10 at the first time 20 and the confirmation information indicates that the second terminal 30 correctly receives the first data packet. A terminal 20 again receives the second side uplink resource used to retransmit the first data packet of the first side uplink HARQ process, and new data retransmission (NDI). Since the NDI indication is usually used to indicate retransmission or new transmission, when this happens, the first terminal 20 can process the second side uplink resource according to the information performed by the first HARQ. Since the first data packet is correctly received by the second terminal 30, the first terminal 20 does not need to retransmit the first data packet on the second side uplink resource. The first terminal ignores the second side uplink resource. Or transmitting other data packets (for example, the second data packet) other than the first data packet can avoid unnecessary transmission by the first terminal 20 and avoid unnecessary feedback by the second terminal 30.

本申请实施例提供一种处理侧行链路资源的方法，该方法的执行主体是第一通信装置。该第一通信装置可以为第一终端20，或者为设置于第一终端20内的芯片，该方法中的第二通信装置可以为第二终端30或者设置于第二终端30内的芯片，下述实施例以第一通信装置为第一终端20，第二通信装置为第二终端30为例。The embodiment of the present application provides a method for processing side link resources, and the execution subject of the method is a first communication device. The first communication device may be the first terminal 20 or a chip set in the first terminal 20. The second communication device in this method may be the second terminal 30 or a chip set in the second terminal 30. In the foregoing embodiment, the first communication device is the first terminal 20 and the second communication device is the second terminal 30 as an example.

图4示出了本申请实施例提供的一种处理侧行链路资源的方法，该方法包括：FIG. 4 shows a method for processing side link resources provided by an embodiment of the present application, and the method includes:

步骤401、第一终端20确定在第一时刻20未向网络设备10发送第一侧行链路HARQ进程的确认信息。该确认信息用于指示第二终端30是否正确接收第一终端20在第一侧行链路资源上向第二终端30发送的第一侧行链路HARQ进程的第一数据包。Step 401: The first terminal 20 determines that the first side uplink HARQ process confirmation information is not sent to the network device 10 at the first time 20. The confirmation information is used to indicate whether the second terminal 30 correctly receives the first data packet of the first side uplink HARQ process sent by the first terminal 20 to the second terminal 30 on the first side uplink resource.

例如，确认信息可以为HARQ信息。确认信息可以是：NACK或ACK。ACK表示第二终端30正确接收第一数据包。NACK表示第二终端30未正确接收第一数据包。具体的，第一数据包可以为第一终端20通过侧行链路在第一侧行链路资源上向第二终端30发送的数据包。该侧行链路指第一终端20和第二终端30之间的侧行链路。第一侧行链路HARQ进程为第一终端20的一个或多个侧行链路HARQ进程中用于传输第一数据包的侧行链路HARQ进程。For example, the confirmation information may be HARQ information. The confirmation information can be: NACK or ACK. ACK indicates that the second terminal 30 correctly receives the first data packet. NACK indicates that the second terminal 30 did not correctly receive the first data packet. Specifically, the first data packet may be a data packet sent by the first terminal 20 to the second terminal 30 on the first side uplink resource through the side uplink. The side link refers to the side link between the first terminal 20 and the second terminal 30. The first side uplink HARQ process is a side link HARQ process used to transmit the first data packet in one or more side link HARQ processes of the first terminal 20.

应理解，本申请实施例提供的方法在步骤401之前还包括：第一终端20在第一侧行链路资源上向第二终端30发送第一数据包。如果第二终端30正确接收第一数据包，则第二终端30向第一终端20发送ACK。如果第二终端30未正确接收第一数据包，则第二终端30向第一终端20发送NACK。It should be understood that, before step 401, the method provided in the embodiment of the present application further includes: the first terminal 20 sends the first data packet to the second terminal 30 on the first side uplink resource. If the second terminal 30 correctly receives the first data packet, the second terminal 30 sends an ACK to the first terminal 20. If the second terminal 30 does not correctly receive the first data packet, the second terminal 30 sends a NACK to the first terminal 20.

第一侧行链路HARQ进程的确认信息表示：该确认信息用于反映与第一侧行链路HARQ进程关联的第一数据包是否被正确接收。The confirmation information of the first side uplink HARQ process indicates: the confirmation information is used to reflect whether the first data packet associated with the first side uplink HARQ process is received correctly.

可以理解的是，本申请实施例中正确接收还可以使用成功接收或者成功解码替换。本申请实施例中未正确接收还可以使用未成功接收或者成功解码替换。下述实施例中以正确接收和未正确接收为例。It is understandable that the correct reception in the embodiment of the present application can also be replaced by successful reception or successful decoding. In the embodiment of the present application, the incorrect reception may also be replaced by unsuccessful reception or successful decoding. In the following embodiments, correct reception and incorrect reception are taken as examples.

本申请实施例中第一侧行链路资源为网络设备10为第一终端20配置的用于传输第一数据包的侧行链路资源。或者第一侧行链路资源为第一终端20从侧行链路资源池中选择的用于传输第一数据包的侧行链路资源。In the embodiment of the present application, the first side link resource is a side link resource configured by the network device 10 for the first terminal 20 to transmit the first data packet. Or the first side link resource is the side link resource selected by the first terminal 20 from the side link resource pool for transmitting the first data packet.

可以理解的是，第一数据包可以为新传数据包。新传数据包即第一终端20第一次(首次)向第二终端30传输的数据包。或者该第一数据包为重传数据包。重传数据包即第一终端2第M次向第二终端30传输的数据包。换句话说重传数据包也即第一终端20非首次向第二终端30传输的数据包。M为大于或等于2的整数，且M小于或等于第一终端20的最大重传次数。或者M小于或等于第一侧行链路HARQ进程的最大重传次数。It is understandable that the first data packet may be a newly transmitted data packet. The newly transmitted data packet is the data packet that the first terminal 20 transmits to the second terminal 30 for the first time (first time). Or the first data packet is a retransmission data packet. The retransmitted data packet is the data packet that the first terminal 2 transmits to the second terminal 30 for the Mth time. In other words, the retransmission data packet is the data packet that the first terminal 20 transmits to the second terminal 30 for the first time. M is an integer greater than or equal to 2, and M is less than or equal to the maximum number of retransmissions of the first terminal 20. Or M is less than or equal to the maximum number of retransmissions of the first side uplink HARQ process.

其中，第一时刻为第一终端20向网络设备10发送确认信息的时刻。The first moment is the moment when the first terminal 20 sends the confirmation information to the network device 10.

本申请实施例中的第一终端未向网络设备发送第一侧行链路HARQ进程的确认信息也可以理解为：确认信息无法传输，或者第一终端20放弃向网络设备10发送确认信息。In the embodiment of the present application, the first terminal not sending the confirmation information of the first side uplink HARQ process to the network device can also be understood as: the confirmation information cannot be transmitted, or the first terminal 20 gives up sending the confirmation information to the network device 10.

步骤402、第一终端20确定第二侧行链路资源。其中，第二侧行链路资源的HARQ参数包括新数据指示(new data indicator，NDI)。Step 402: The first terminal 20 determines the second side uplink resource. Among them, the HARQ parameter of the second side uplink resource includes a new data indicator (NDI).

可选的，该HARQ参数还可以包括进程号(HARQ Process ID)。Optionally, the HARQ parameter may also include a process ID (HARQ Process ID).

示例性的，该第二侧行链路资源可以由网络设备10配置给第一终端20。也即在第一终端20在第一时刻未向第二终端30发送确认信息的情况下，网络设备10未接收到确认信息的情况下，网络设备10为第一终端20配置第二侧行链路资源。Exemplarily, the second side link resource may be configured by the network device 10 to the first terminal 20. That is, when the first terminal 20 does not send confirmation information to the second terminal 30 at the first moment, and the network device 10 does not receive the confirmation information, the network device 10 configures the second side chain for the first terminal 20 Road resources.

示例性的，网络设备10向第一终端20发送PDCCH，该PDCCH用于调度第一终端20重传第一数据包，且该PDCCH还用于指示第二侧行链路资源的位置以及第二侧 行链路资源对应的HARQ进程号。例如，PDCCH携带的下行控制信息(down control information，DCI)用于调度SL授权(Grant)，以及SL Grant对应的NDI以及HARQ process ID。SL Grant用于确定第二侧行链路资源的位置。Exemplarily, the network device 10 sends a PDCCH to the first terminal 20. The PDCCH is used to schedule the first terminal 20 to retransmit the first data packet, and the PDCCH is also used to indicate the location of the second side uplink resource and the second HARQ process ID corresponding to the side link resource. For example, the downlink control information (DCI) carried by the PDCCH is used to schedule the SL grant (Grant), and the NDI and HARQ process ID corresponding to the SL Grant. SL Grant is used to determine the location of the second side uplink resource.

该第二侧行链路资源可以为第一终端20在第三时刻接收到的，该第三时刻位于第一时刻之后。The second side link resource may be received by the first terminal 20 at a third time, which is located after the first time.

可以理解的是，第二侧行链路资源为确认信息为ACK时，且第一时刻20未向网络设备10发送确认信息的情况下第一终端20接收到的。It is understandable that the second side link resource is received by the first terminal 20 when the confirmation information is ACK and the confirmation information is not sent to the network device 10 at the first time 20.

步骤403、在确认信息指示第二终端30正确接收第一数据包的情况下，第一终端20根据HARQ参数，处理第二侧行链路资源。Step 403: In the case where the confirmation information indicates that the second terminal 30 correctly receives the first data packet, the first terminal 20 processes the second side uplink resource according to the HARQ parameter.

本申请实施例提供一种处理侧行链路资源的方法，该方法中第一终端可以在确定在第一时刻未向网络设备发送确认信息，以及该确认信息指示第二终端正确接收第一数据包的情况下，如果第一终端又接收到第二侧行链路资源。由于第二侧行链路资源的HARQ参数包括NDI指示。NDI指示通常用于指示重传或者新传，当发生该情况时，第一终端可以根据HARQ参数，处理该第二侧行链路资源。由于第一数据包被第二终端正确接收，因此，第一终端不需要对第一数据包进行重传，通过对第二侧行链路资源作处理可以避免第一终端的不必要的传输，以及避免第二终端不必要的反馈。The embodiment of the present application provides a method for processing side link resources. In the method, the first terminal may determine that no confirmation information is sent to the network device at the first moment, and the confirmation information indicates that the second terminal correctly receives the first data In the case of packets, if the first terminal receives the second side uplink resource again. Because the HARQ parameter of the second side uplink resource includes an NDI indication. The NDI indication is usually used to indicate retransmission or new transmission. When this happens, the first terminal can process the second side uplink resource according to the HARQ parameters. Since the first data packet is correctly received by the second terminal, the first terminal does not need to retransmit the first data packet, and unnecessary transmission by the first terminal can be avoided by processing the second side uplink resources. And to avoid unnecessary feedback from the second terminal.

作为本申请的另一个实施例，如图5所示，本申请实施例中的步骤401具体可以通过以下方式实现：As another embodiment of the present application, as shown in FIG. 5, step 401 in the embodiment of the present application can be specifically implemented in the following manner:

步骤4011、第一终端20确定发送确认信息的时刻与第一终端20发送第一消息的时刻均为第一时刻。Step 4011, the first terminal 20 determines that the time when the confirmation information is sent and the time when the first terminal 20 sends the first message are both the first time.

也即发送确认信息的时刻与第一终端20发送第一消息的时刻相同，即发送确认信息的时刻与第一终端20发送第一消息的时刻在时间上冲突或者重叠。That is, the time when the confirmation information is sent is the same as the time when the first terminal 20 sends the first message, that is, the time when the confirmation information is sent and the time when the first terminal 20 sends the first message conflict or overlap in time.

第一终端20可以根据承载确认信息的物理上行信道的优先级与第一消息的优先级的比较，或者承载确认信息的物理上行信道的优先级与承载第一消息的侧行链路信道的优先级的比较，确定在第一时刻20是否未向网络设备10发送确认信息。例如，可以通过步骤4012实现：The first terminal 20 may compare the priority of the physical uplink channel carrying the confirmation information with the priority of the first message, or the priority of the physical uplink channel carrying the confirmation information and the priority of the side link channel carrying the first message. The comparison of levels determines whether the confirmation information is not sent to the network device 10 at the first time 20. For example, it can be achieved through step 4012:

步骤4012、在承载确认信息的物理上行信道的优先级低于第一消息的优先级，或者承载确认信息的物理上行信道的优先级低于承载第一消息的侧行链路信道的优先级的情况下，第一终端20确定在第一时刻20未向网络设备10发送确认信息。Step 4012, when the priority of the physical uplink channel carrying the confirmation information is lower than the priority of the first message, or the priority of the physical uplink channel carrying the confirmation information is lower than the priority of the side link channel carrying the first message In this case, the first terminal 20 determines that the confirmation information is not sent to the network device 10 at the first time 20.

示例性的，发送确认信息的时刻与第一终端20发送第一消息的时刻在时间上的冲突或者重叠包括下述内容：Exemplarily, the time conflict or overlap between the time when the confirmation information is sent and the time when the first terminal 20 sends the first message includes the following content:

示例1-1)、第一消息为第一终端20在随机接入过程中向网络设备10发送的消息。Example 1-1). The first message is a message sent by the first terminal 20 to the network device 10 during the random access process.

示例性的，第一消息可以为随机接入过程中的消息1(message1，Msg1)。消息1通过物理随机接入信道(physical random access channel，PRACH)发送。或者第一消息可以为随机接入过程中的消息3(Msg3)。消息3通过物理上行共享信道(physical uplink shared channel，PUSCH)。Exemplarily, the first message may be message 1 (message1, Msg1) in the random access process. Message 1 is sent through a physical random access channel (PRACH). Or the first message may be message 3 (Msg3) in the random access process. Message 3 passes through the physical uplink shared channel (PUSCH).

也即如果第一终端20通过物理上行信道传输确认信息的时刻与随机接入过程中发送消息1或消息3的时刻相同，那么承载确认信息的物理上行信道的优先级低于消息1或消息3的优先级，即第一终端20优先传输消息1或消息3，而放弃传输确认信 息。因此，第一终端20在第一时刻未向网络设备10发送确认信息。That is, if the time when the first terminal 20 transmits the confirmation information through the physical uplink channel is the same as the time when the message 1 or message 3 is sent in the random access process, then the priority of the physical uplink channel carrying the confirmation information is lower than that of the message 1 or message 3. The priority of the first terminal 20, that is, the first terminal 20 transmits message 1 or message 3 first, and discards the transmission confirmation information. Therefore, the first terminal 20 does not send confirmation information to the network device 10 at the first moment.

示例1-2)、物理上行信道为上行物理控制信道(physical uplink control channel，PUCCH)，第一消息为侧行链路SL媒体接入控制(medium access control，MAC)协议数据单元(protocol data unit，PDU)，承载第一消息的侧行链路信道为侧行链路共享信道(sindlink shared channel，SL-SCH)。也即第一时刻，第一终端20需要通过PUCCH向网络设备10发送确认信息时，也需要在侧行链路SL上向第二终端20或其他终端发送SL MAC PDU。该SL MAC PDU通常可以包括来自一个或多个来自不同侧行链路逻辑信道的SL MAC业务数据单元(service data unit，SDU)。该不同侧行链路逻辑信道的优先级不同。Example 1-2). The physical uplink channel is the physical uplink control channel (PUCCH), and the first message is the side link SL medium access control (MAC) protocol data unit (protocol data unit) , PDU), the side link channel carrying the first message is a side link shared channel (sindlink shared channel, SL-SCH). That is, at the first moment, when the first terminal 20 needs to send confirmation information to the network device 10 through the PUCCH, it also needs to send an SL MAC PDU to the second terminal 20 or other terminals on the side link SL. The SL MAC PDU may generally include one or more SL MAC service data units (SDU) from different side link logical channels. The different side link logical channels have different priorities.

相应的，本申请实施例中步骤4012中，第一终端20根据承载确认信息的物理上行信道的优先级、以及承载第一消息的侧行链路信道的优先级，确定在第一时刻20未向网络设备10发送确认信息，包括：在第一时刻承载确认信息的PUCCH的优先级低于SL-SCH所映射的物理侧行链路共享信道(physical sidelink shared channel，PSSCH)的优先级的情况下，第一终端20在第一时刻未向网络设备10发送确认信息。Correspondingly, in step 4012 in the embodiment of the present application, the first terminal 20 determines that at the first time 20 the first terminal 20 according to the priority of the physical uplink channel carrying the confirmation information and the priority of the side uplink channel carrying the first message Sending confirmation information to the network device 10, including: the priority of the PUCCH carrying the confirmation information at the first moment is lower than the priority of the physical sidelink shared channel (PSSCH) mapped by the SL-SCH Next, the first terminal 20 does not send confirmation information to the network device 10 at the first moment.

也即，如果承载确认信息的PUCCH的优先级低于SL-SCH传输的优先级，则第一终端20优先传输SL-SCH/PSSCH，而放弃传输PUCCH。因此，第一终端20确定在第一时刻20未向网络设备10发送确认信息。That is, if the priority of the PUCCH carrying the confirmation information is lower than the priority of SL-SCH transmission, the first terminal 20 preferentially transmits the SL-SCH/PSSCH and gives up transmitting the PUCCH. Therefore, the first terminal 20 determines that the confirmation information is not sent to the network device 10 at the first time 20.

在示例1-2)中，优先传输SL-SCH/PSSCH，而放弃传输PUCCH由第一终端的物理层执行。In Example 1-2), the SL-SCH/PSSCH is transmitted preferentially, and the PUCCH transmission is abandoned by the physical layer of the first terminal.

本申请实施例中，承载确认信息的PUCCH的优先级和SL-SCH所映射的PSSCH的优先级的高低取决于确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道与SL-SCH要传输的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级的比较。In the embodiment of this application, the priority of the PUCCH carrying the confirmation information and the priority of the PSSCH mapped by the SL-SCH depend on the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation information and the SL- Comparison of the priority of the side link logical channel with the highest priority in the SL MAC PDU to be transmitted by the SCH.

应理解，网络设备10可以提前为第一终端20在PUCCH上配置发送确认信息的资源。It should be understood that the network device 10 may configure the resource for sending the confirmation information on the PUCCH for the first terminal 20 in advance.

其中，确认信息对应的SL MAC PDU是指：该确认信息所针对的SL MAC PDU。Among them, the SL MAC PDU corresponding to the confirmation information refers to the SL MAC PDU to which the confirmation information is aimed.

比如说，确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级低于在SL-SCH上传输的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级，第一终端20确定传输确认信息的上行物理控制信道的优先级低于承载SL MAC PDU的SL-SCH所映射的PSSCH的优先级。For example, the priority of the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation message is lower than the priority of the side link logical channel with the highest priority in the SL MAC PDU transmitted on the SL-SCH The first terminal 20 determines that the priority of the uplink physical control channel for transmitting the confirmation information is lower than the priority of the PSSCH mapped to the SL-SCH carrying the SL MAC PDU.

示例1-3)、物理上行信道为上行物理共享信道(physical uplink shared channel，PUSCH)，第一消息为承载SL MAC PDU，承载第一消息的侧行链路信道为SL-SCH。Example 1-3). The physical uplink channel is a physical uplink shared channel (PUSCH), the first message is to carry SL MAC PDU, and the side link channel that carries the first message is SL-SCH.

第一终端20根据承载确认信息的物理上行信道的优先级、以及承载第一消息的侧行链路信道的优先级，确定在第一时刻20是否向网络设备10发送确认信息。例如，第一终端20根据承载确认信息的物理上行信道的优先级、以及承载第一消息的侧行链路信道的优先级，确定在第一时刻20确定未向网络设备10发送确认信息。The first terminal 20 determines whether to send the confirmation information to the network device 10 at the first time 20 according to the priority of the physical uplink channel carrying the confirmation information and the priority of the side link channel carrying the first message. For example, according to the priority of the physical uplink channel carrying the confirmation information and the priority of the side link channel carrying the first message, the first terminal 20 determines that the confirmation information is not sent to the network device 10 at the first time 20.

相应的，本申请实施例中步骤4012中，第一终端20根据承载确认信息的物理上行信道的优先级、以及承载第一消息的侧行链路信道的优先级，确定在第一时刻20未向网络设备10发送确认信息，包括：Correspondingly, in step 4012 in the embodiment of the present application, the first terminal 20 determines that at the first time 20 the first terminal 20 according to the priority of the physical uplink channel carrying the confirmation information and the priority of the side uplink channel carrying the first message Send confirmation information to the network device 10, including:

如果PUSCH的优先级低于SL-SCH的优先级，第一终端20确定在第一时刻20是否向网络设备10发送确认信息。例如，如果PUSCH的优先级低于SL-SCH的优先级，第一终端20确定在第一时刻20未向网络设备10发送确认信息。If the priority of PUSCH is lower than the priority of SL-SCH, the first terminal 20 determines whether to send confirmation information to the network device 10 at the first time 20. For example, if the priority of PUSCH is lower than the priority of SL-SCH, the first terminal 20 determines that no confirmation information is sent to the network device 10 at the first time 20.

由于PUSCH通常可以用于传输第一终端20向网络设备10发送的MAC PDU，因此，当确认信息和在PUSCH上传输的MAC PDU可以复用该PUSCH时，无论在该PUSCH上要传输的确认信息为ACK还是NACK，可以通过比较PUSCH上传输的MAC PDU中优先最高的上行链路逻辑信道与SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级，即可以确定PUSCH的优先级和SL-SCH的优先级。Since the PUSCH can generally be used to transmit the MAC PDU sent by the first terminal 20 to the network device 10, when the confirmation information and the MAC PDU transmitted on the PUSCH can be multiplexed with the PUSCH, regardless of the confirmation information to be transmitted on the PUSCH Whether it is ACK or NACK can be determined by comparing the priority of the uplink logical channel with the highest priority in the MAC PDU transmitted on the PUSCH with the priority of the side link logical channel in the MAC PDU transmitted on the SL-SCH. PUSCH priority and SL-SCH priority.

可选的，示例1-3中PUSCH的优先级和SL-SCH的优先级的比较和处理由第一终端20的MAC层执行。Optionally, the comparison and processing of the priority of the PUSCH and the priority of the SL-SCH in Examples 1-3 are performed by the MAC layer of the first terminal 20.

参考一种可能示例1-3-1，如果在PUSCH上传输的MAC PDU中优先级最高的上行链路逻辑信道的优先级低于在SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级，则第一终端确定PUSCH的优先级低于SL-SCH的优先级。Referring to a possible example 1-3-1, if the priority of the uplink logical channel with the highest priority among the MAC PDUs transmitted on the PUSCH is lower than the side row with the highest priority among the MAC PDUs transmitted on the SL-SCH Link logical channel priority, the first terminal determines that the PUSCH priority is lower than the SL-SCH priority.

可以理解的是，在PUSCH上传输的MAC PDU中包括来自一个或多个上行链路逻辑信道的MAC SDU，该一个或多个上行链路逻辑的优先级可以相同或者不同。在SL-SCH上传输的MAC PDU中也可以包括来自一个或多个侧行链路逻辑信道的MAC SDU，该一个或多个侧行链路逻辑信道的优先级可以相同或者不同。It can be understood that the MAC PDU transmitted on the PUSCH includes MAC SDUs from one or more uplink logical channels, and the priority of the one or more uplink logical channels may be the same or different. The MAC PDU transmitted on the SL-SCH may also include MAC SDUs from one or more side link logical channels, and the priority of the one or more side link logical channels may be the same or different.

举例说明，PUSCH上传输的MAC PDU中优先级最高的上行链路逻辑信道为上行链路逻辑信道1。SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道为侧行链路逻辑信道1，若侧行链路逻辑信道1的优先级高于上行链路逻辑信道1的优先级，则第一终端20确定PUSCH的优先级低于SL-SCH的优先级。For example, in the MAC PDU transmitted on the PUSCH, the uplink logical channel with the highest priority is uplink logical channel 1. The side-link logical channel with the highest priority in the MAC PDU transmitted on the SL-SCH is the side-link logical channel 1. If the priority of the side-link logical channel 1 is higher than the priority of the uplink logical channel 1. , The first terminal 20 determines that the priority of PUSCH is lower than the priority of SL-SCH.

参考一种可能的示例1-3-2，如果确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级，和在PUSCH上传输的MAC PDU中优先最高的上行链路逻辑信道的优先级均低于在SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级，则第一终端20确定PUSCH的优先级低于SL-SCH的优先级。Refer to a possible example 1-3-2, if the priority of the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation information, and the uplink with the highest priority in the MAC PDU transmitted on the PUSCH The priority of the logical channel is lower than the priority of the side link logical channel with the highest priority among the MAC PDUs transmitted on the SL-SCH, the first terminal 20 determines that the priority of the PUSCH is lower than the priority of the SL-SCH .

示例性的，a)表示确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级。b)表示在PUSCH上传输的MAC PDU中优先最高的上行链路逻辑信道的优先级均。c)在SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级。如果a)的优先级或b)的优先级高于c)的优先级，那么第一终端20确定PUSCH的优先级高于SL-SCH/PSSCH的优先级，即传输PUCCH，而放弃SL-SCH/PSSCH的传输。如果a)的优先级和b)的优先级均低于c)的优先级，那么第一终端20确定PUSCH的优先级低于SL-SCH/PSSCH的优先级，即传输SL-SCH/PSSCH,而放弃PUSCH的传输。Exemplarily, a) indicates the priority of the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation information. b) Represents the priority of the uplink logical channel with the highest priority among the MAC PDUs transmitted on the PUSCH. c) The priority of the side link logical channel with the highest priority among the MAC PDUs transmitted on the SL-SCH. If the priority of a) or the priority of b) is higher than the priority of c), then the first terminal 20 determines that the priority of PUSCH is higher than the priority of SL-SCH/PSSCH, that is, transmits PUCCH, and discards SL-SCH /PSSCH transmission. If the priority of a) and the priority of b) are both lower than the priority of c), then the first terminal 20 determines that the priority of PUSCH is lower than the priority of SL-SCH/PSSCH, that is, transmitting SL-SCH/PSSCH, And give up PUSCH transmission.

可选的，示例1-3-2中，PUSCH的优先级和SL-SCH的优先级的比较和处理由第一终端20的MAC层执行。Optionally, in Example 1-3-2, the comparison and processing of the priority of the PUSCH and the priority of the SL-SCH are performed by the MAC layer of the first terminal 20.

或者，本申请实施例中第一终端20向网络设备10发送了确认信息，但是网络设备10未正确接收到该确认信息，则第一终端20确定未向网络设备10发送确认信息。Alternatively, in the embodiment of the present application, the first terminal 20 sends confirmation information to the network device 10, but the network device 10 does not correctly receive the confirmation information, the first terminal 20 determines that the confirmation information is not sent to the network device 10.

作为本申请的另一个实施例，如图5或图6所示，本申请实施例提供的方法还包括：As another embodiment of the present application, as shown in FIG. 5 or FIG. 6, the method provided in the embodiment of the present application further includes:

第一终端20根据承载确认信息的物理上行信道的优先级、第一消息的优先级，或者承载确认信息的物理上行信道的优先级和第一消息的侧行链路信道的优先级的比较，第一终端20在第一时刻优先向网络设备10发送确认信息。The first terminal 20 compares the priority of the physical uplink channel carrying the confirmation information and the priority of the first message, or the priority of the physical uplink channel carrying the confirmation information and the priority of the side link channel of the first message, The first terminal 20 preferentially sends confirmation information to the network device 10 at the first moment.

具体的，步骤404、在承载确认信息的物理上行信道的优先级高于第一消息的优先级，或者承载确认信息的物理上行信道的优先级高于承载第一消息的侧行链路信道的优先级的情况下，第一终端20确定在第一时刻优先向网络设备10发送确认信息。Specifically, in step 404, the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the first message, or the priority of the physical uplink channel carrying the confirmation information is higher than that of the side link channel carrying the first message. In the case of priority, the first terminal 20 determines to send the confirmation information to the network device 10 first at the first moment.

比如说，本申请实施例中第一终端20确定承载确认信息的物理上行信道的优先级高于第一消息的优先级可以通过以下方式实现：如果承载确认信息的物理上行信道的优先级高于消息1或消息3的优先级的情况下，第一终端20确定承载确认信息的上行信道的优先级高于第一消息的优先级。For example, in the embodiment of the present application, the first terminal 20 determines that the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the first message can be achieved in the following manner: if the priority of the physical uplink channel carrying the confirmation information is higher than In the case of the priority of message 1 or message 3, the first terminal 20 determines that the priority of the uplink channel carrying the confirmation information is higher than the priority of the first message.

比如说，本申请实施例中第一终端20确定承载确认信息的物理上行信道的优先级高于承载第一消息的侧行链路信道的优先级可以通过以下方式实现：如果承载确认信息的PUCCH的优先级高于SL-SCH传输的优先级，第一终端20确定承载确认信息的物理上行信道的优先级高于承载第一消息的侧行链路信道的优先级。For example, in the embodiment of the present application, the first terminal 20 determines that the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the side link channel carrying the first message can be implemented in the following manner: If the PUCCH carrying the confirmation information The priority of is higher than the priority of SL-SCH transmission, and the first terminal 20 determines that the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the side link channel carrying the first message.

示例性的，如果确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级高于在SL-SCH上传输的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级，第一终端20确定承载确认信息的PUCCH的优先级高于SL-SCH传输的优先级。Exemplarily, if the priority of the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation information is higher than that of the side link logical channel with the highest priority in the SL MAC PDU transmitted on the SL-SCH Priority: The first terminal 20 determines that the priority of the PUCCH carrying the confirmation information is higher than the priority of SL-SCH transmission.

参考该实现方式，本申请实施例中第一终端20确定承载确认信息的物理上行信道的优先级高于承载第一消息的侧行链路信道的优先级可以通过以下方式实现：如果PUSCH的优先级高于SL-SCH的优先级，第一终端20确定承载确认信息的物理上行信道的优先级高于承载第一消息的侧行链路信道的优先级。With reference to this implementation, in the embodiment of the present application, the first terminal 20 determines that the priority of the physical uplink channel that carries the confirmation information is higher than the priority of the sidelink channel that carries the first message can be implemented in the following manner: If the PUSCH has priority The priority is higher than the priority of the SL-SCH, and the first terminal 20 determines that the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the side link channel carrying the first message.

示例性的，如果在PUSCH上传输的MAC PDU中优先级最高的上行链路逻辑信道的优先级高于在SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级，则第一终端确定PUSCH的优先级高于SL-SCH的优先级。Exemplarily, if the priority of the uplink logical channel with the highest priority in the MAC PDU transmitted on the PUSCH is higher than the priority of the side link logical channel with the highest priority in the MAC PDU transmitted on the SL-SCH , The first terminal determines that the priority of PUSCH is higher than the priority of SL-SCH.

示例性的，在示例1-3-2中，如果a)的优先级或b)的优先级高于c)的优先级，那么第一终端20确定PUSCH的优先级高于SL-SCH/PSSCH的优先级，即传输PUCCH，而放弃SL-SCH/PSSCH的传输。Exemplarily, in Example 1-3-2, if the priority of a) or the priority of b) is higher than the priority of c), then the first terminal 20 determines that the priority of PUSCH is higher than that of SL-SCH/PSSCH The priority is to transmit PUCCH and give up SL-SCH/PSSCH transmission.

作为本申请的另一个实施例，如图5所示，本申请实施例中的步骤403具体可以通过以下步骤4031或步骤4032实现：As another embodiment of the present application, as shown in FIG. 5, step 403 in the embodiment of the present application can be specifically implemented by the following step 4031 or step 4032:

步骤4031、第一终端根据HARQ参数，在第二侧行链路资源上传输第二数据包。Step 4031. The first terminal transmits the second data packet on the second side uplink resource according to the HARQ parameter.

其中，第二数据包与第一数据包不同。第二数据包可以为新传的数据包，也可以为重传的数据包。Wherein, the second data packet is different from the first data packet. The second data packet may be a newly transmitted data packet or a retransmitted data packet.

需要说明的是，本申请实施例中第一终端20还可以针对第一终端20的一个或多个侧行链路HARQ进程中每个侧行链路HARQ进程关联一个第一变量(例如定义为SL_HARQ_Feedback)。任一个侧行链路HARQ进程关联的第一变量，用于反映第一终端20发送的该任一个侧行链路HARQ进程的数据包是否被对侧正确接收。示例性的，本申请实施例中每个侧行链路HARQ进程具有一个进程号。每个侧行链路HARQ进程关联一个第一变量指：每个侧行链路HARQ进程的进程号与一个第一变量关联。It should be noted that the first terminal 20 in the embodiment of the present application may also associate a first variable (for example, defined as: for each side link HARQ process in one or more side link HARQ processes of the first terminal 20) SL_HARQ_Feedback). The first variable associated with any side-link HARQ process is used to reflect whether the data packet of any side-link HARQ process sent by the first terminal 20 is correctly received by the opposite side. Exemplarily, each side link HARQ process in the embodiment of the present application has a process number. The association of each side link HARQ process with a first variable means that the process number of each side link HARQ process is associated with a first variable.

示例性的，本申请实施例提供的方法还包括：第一终端20根据HARQ参数中携带的进程号，在进程号为第一侧行链路HARQ进程的进程号的情况下，第一终端20确定第一侧行链路HARQ进程关联的第一变量。该第一变量用于反映第二终端30是否正确接收第一数据包。该第一变量的值可以为第一参数值或第二参数值。其中，第一参数值表示所述第二终端30正确接收第一数据包，第二参数值表示第二终端30未正确接收所述第一数据包。也即如果第一终端20确定第二终端30正确接收第一数据包的情况下，如果第一终端20又接收到了第二侧行链路资源，则第一终端20可以通过第二侧行链路资源对应的HARQ参数的进程号，确定第二侧行链路资源对应的HARQ进程的第一变量的值。如果第二侧行链路资源对应的HARQ进程的第一变量的值为第一参数值，则第一终端20确定该第二侧行链路资源可以不用做重传第一数据包的资源。Exemplarily, the method provided in the embodiment of the present application further includes: the first terminal 20 according to the process number carried in the HARQ parameter, in the case that the process number is the process number of the first side uplink HARQ process, the first terminal 20 Determine the first variable associated with the first side uplink HARQ process. The first variable is used to reflect whether the second terminal 30 correctly receives the first data packet. The value of the first variable may be the first parameter value or the second parameter value. The first parameter value indicates that the second terminal 30 correctly receives the first data packet, and the second parameter value indicates that the second terminal 30 does not correctly receive the first data packet. That is, if the first terminal 20 determines that the second terminal 30 correctly receives the first data packet, if the first terminal 20 receives the second side link resource again, the first terminal 20 can pass through the second side link resource. The process number of the HARQ parameter corresponding to the channel resource determines the value of the first variable of the HARQ process corresponding to the second side uplink resource. If the value of the first variable of the HARQ process corresponding to the second side uplink resource is the first parameter value, the first terminal 20 determines that the second side uplink resource may not be used as a resource for retransmitting the first data packet.

本申请实施例步骤4031的一种可能的实现方式为：在NDI指示新传，HARQ进程号为第二侧行链路HARQ进程的进程号的情况下，如果第一侧行链路HARQ进程关联的第一变量的值为第一参数值的情况下，第一终端20在第二侧行链路资源上向第二终端30传输第二数据包。也即网络设备10通过NDI指示第一终端20在第二侧行链路资源上向第二终端30传输第二数据包。A possible implementation of step 4031 in the embodiment of the present application is: when NDI indicates new transmission and the HARQ process number is the process number of the second side uplink HARQ process, if the first side uplink HARQ process is associated When the value of the first variable of is the first parameter value, the first terminal 20 transmits the second data packet to the second terminal 30 on the second side uplink resource. That is, the network device 10 instructs the first terminal 20 to transmit the second data packet to the second terminal 30 on the second side uplink resource through the NDI.

本申请实施例步骤4031的另一种可能的实现方式为：在NDI指示新传，HARQ进程号为第二侧行链路HARQ进程的进程号的情况下，第一终端20在第二侧行链路资源上向第二终端30传输第二数据包。该第二数据包与第二侧行链路HARQ进程对应。也即如果网络设备10通过NDI指示第一终端20进行新传的情况下，第一终端20可以在第二侧行链路资源上传输第二侧行链路HARQ进程对应的第二数据包。Another possible implementation of step 4031 in the embodiment of the present application is: when the NDI indicates new transmission and the HARQ process number is the process number of the HARQ process on the second side link, the first terminal 20 is on the second side. The second data packet is transmitted to the second terminal 30 on the link resource. The second data packet corresponds to the second side uplink HARQ process. That is, if the network device 10 instructs the first terminal 20 to perform a new transmission through the NDI, the first terminal 20 may transmit the second data packet corresponding to the second side uplink HARQ process on the second side uplink resource.

此外，还可以理解的是，在NDI指示新传的情况下，第一终端20确定第一侧行链路HARQ进程的HARQ缓存为空，则第一终端20可以在第二侧行链路资源上传输第二数据包。In addition, it can also be understood that when the NDI indicates a new transmission, the first terminal 20 determines that the HARQ buffer of the first side link HARQ process is empty, and the first terminal 20 can use the second side link resource The second data packet is transmitted on.

需要说明的是，如果NDI指示重传，且第一变量的值为第二参数值的情况下，第一终端20需要在第二侧行链路资源上重传第一数据包。It should be noted that if the NDI indicates retransmission and the value of the first variable is the second parameter value, the first terminal 20 needs to retransmit the first data packet on the second side uplink resource.

如果NDI指示重传，且第一侧行链路HARQ进程的HARQ缓存不为空的情况下，第一终端20需要在第二侧行链路资源上传输第一数据包。If the NDI indicates retransmission and the HARQ buffer of the first side uplink HARQ process is not empty, the first terminal 20 needs to transmit the first data packet on the second side uplink resource.

步骤4032、第一终端根据HARQ参数，忽略(ignore)第二侧行链路资源。Step 4032, the first terminal ignores (ignore) the second side uplink resource according to the HARQ parameter.

本申请实施例中第一终端忽略(ignore)第二侧行链路资源可以理解为：第一终端不使用第二侧行链路资源传输第一数据包。The ignoring of the second side link resource by the first terminal in the embodiment of the present application can be understood as: the first terminal does not use the second side link resource to transmit the first data packet.

相应的，作为一种可能的实现方式，本申请实施例中的步骤4032具体可以通过以下方式实现：在NDI指示重传，且HARQ进程号为所述第一侧行链路HARQ进程的进程号，以及第一侧行链路HARQ进程关联的第一变量的值为第一参数值的情况下，第一终端20忽略第二侧行链路资源。Correspondingly, as a possible implementation manner, step 4032 in the embodiment of this application can be specifically implemented in the following manner: retransmission is indicated in NDI, and the HARQ process number is the process number of the first side uplink HARQ process , And when the value of the first variable associated with the first side uplink HARQ process is the first parameter value, the first terminal 20 ignores the second side uplink resource.

需要说明的是，由于网络设备10在向第一终端20分配第二侧行链路资源时，向第一终端20提供了进程号，因此，如果该HARQ参数包括的HARQ进程号与第一侧行链路HARQ进程的进程号相同的情况下，第一终端20可以根据第一侧行链路HARQ进程的进程号确定第一侧行链路HARQ进程关联的第一变量的参数值。It should be noted that, since the network device 10 provides the process number to the first terminal 20 when allocating the second side uplink resource to the first terminal 20, if the HARQ process number included in the HARQ parameter is different from the first side uplink resource When the process numbers of the uplink HARQ processes are the same, the first terminal 20 may determine the parameter value of the first variable associated with the first side uplink HARQ process according to the process number of the first side uplink HARQ process.

需要说明的是，本申请实施例提供的方法还包括：第一终端20根据来自第二终端30的确认信息，确定第一侧行链路HARQ进程关联的第一变量的值。It should be noted that the method provided in the embodiment of the present application further includes: the first terminal 20 determines the value of the first variable associated with the first side uplink HARQ process according to the confirmation information from the second terminal 30.

具体的，如果确认信息为ACK，则第一终端确定第一侧行链路HARQ进程关联的第一变量的值为第一参数值。如果确认信息为NACK，则第一终端确定第一侧行链路HARQ进程关联的第一变量的值为第二参数值。Specifically, if the confirmation information is ACK, the first terminal determines that the value of the first variable associated with the first side uplink HARQ process is the first parameter value. If the confirmation information is NACK, the first terminal determines that the value of the first variable associated with the first side uplink HARQ process is the second parameter value.

作为另一种可能的实现方式，本申请实施例中的步骤4032具体可以通过以下方式实现：在NDI指示重传，且第一侧行链路HARQ进程的HARQ(buffer)缓存为空，第一终端20忽略第二侧行链路资源。As another possible implementation manner, step 4032 in the embodiment of the present application can be specifically implemented in the following manner: retransmission is indicated in NDI, and the HARQ (buffer) buffer of the first side uplink HARQ process is empty, and the first The terminal 20 ignores the second side uplink resource.

可以理解的是，本申请实施例提供的方法还包括：第一终端20确定第一侧行链路HARQ进程的第一数据包已经成功被第二终端30接收到，第一终端20将第一侧行链路HARQ进程的HARQ buffer清空。It is understandable that the method provided in the embodiment of the present application further includes: the first terminal 20 determines that the first data packet of the first side uplink HARQ process has been successfully received by the second terminal 30, and the first terminal 20 first The HARQ buffer of the side link HARQ process is cleared.

上述通过步骤401-步骤404主要描述了在第一时刻20未向网络设备10发送确认信息的情况下，且确认信息指示第二终端30正确接收第一数据包的情况下，如果第一终端20又接收到了第二侧行链路资源的情况下，第一终端20根据第二侧行链路资源的HARQ参数处理第二侧行链路资源的过程。但是，在实际过程中，第二终端30可能正确接收了第一数据包，也即确认信息为NACK，则表示第一终端20需要对第一数据包进行重传，在第一时刻需要反馈NACK给网络设备10，以便网络设备10接收到NACK后确定第一数据包未被正确接收，可以为第一终端20分配重传第一数据包的第二侧行链路资源。但是，由于第一终端20未向网络设备10反馈NACK，因此第一终端20还可以通过下述实施例处理第一数据包。The above steps 401 to 404 mainly describe the case where the confirmation information is not sent to the network device 10 at the first time 20, and the confirmation information indicates that the second terminal 30 correctly receives the first data packet, if the first terminal 20 When the second side uplink resource is received again, the first terminal 20 processes the second side uplink resource according to the HARQ parameter of the second side uplink resource. However, in the actual process, the second terminal 30 may correctly receive the first data packet, that is, the confirmation information is NACK, which means that the first terminal 20 needs to retransmit the first data packet and needs to feed back the NACK at the first moment. To the network device 10 so that the network device 10 determines that the first data packet is not received correctly after receiving the NACK, and can allocate the second side uplink resource for the first terminal 20 to retransmit the first data packet. However, since the first terminal 20 does not feed back NACK to the network device 10, the first terminal 20 may also process the first data packet through the following embodiments.

结合图6，本申请实施例提供的一种发送侧行链路资源的方法，包括：With reference to FIG. 6, a method for transmitting side link resources provided by an embodiment of the present application includes:

步骤601、第一终端20确定在第一时刻20未向网络设备10发送第一侧行链路HARQ进程的确认信息。该确认信息用于指示第二终端30是否正确接收第一终端20在第一侧行链路资源上向第二终端30发送的第一侧行链路HARQ进程的第一数据包。Step 601: The first terminal 20 determines that the first side uplink HARQ process confirmation information is not sent to the network device 10 at the first time 20. The confirmation information is used to indicate whether the second terminal 30 correctly receives the first data packet of the first side uplink HARQ process sent by the first terminal 20 to the second terminal 30 on the first side uplink resource.

步骤601的具体实现可以参考上述步骤401、步骤4011以及步骤4012处的描述，此处不再赘述。For the specific implementation of step 601, reference may be made to the description of step 401, step 4011, and step 4012, which will not be repeated here.

步骤602、第一终端20确定用于重新传输第一数据包的第三侧行链路资源。Step 602: The first terminal 20 determines a third side uplink resource used to retransmit the first data packet.

示例性的，该用于重新传输第一数据包的第三侧行链路资源可以为第一终端20从网络设备10处获取到的。或者该用于重新传输第一数据包的第三侧行链路资源可以由第一终端20自主选择得到。Exemplarily, the third side link resource used to retransmit the first data packet may be obtained by the first terminal 20 from the network device 10. Or, the third side link resource used to retransmit the first data packet may be independently selected by the first terminal 20.

步骤603、在确认信息指示第二终端30未正确接收第一数据包的情况下，第一终端20通过第三侧行链路资源向第二终端30发送第一数据包。Step 603: When the confirmation information indicates that the second terminal 30 did not correctly receive the first data packet, the first terminal 20 sends the first data packet to the second terminal 30 through the third side uplink resource.

也即如果确认信息为NACK，则第一终端20需要重新传输第一数据包的第三侧行链路资源后，利用该第三侧行链路资源重新传输第一数据包。That is, if the confirmation information is NACK, the first terminal 20 needs to retransmit the third side uplink resource of the first data packet, and then use the third side uplink resource to retransmit the first data packet.

具体的，第一终端20可以在第一时刻之后通过第一终端20和第二终端30之间的侧行链路在第三侧行链路资源向第二终端30发送第一数据包。Specifically, the first terminal 20 may send the first data packet to the second terminal 30 on the third side uplink resource through the side uplink between the first terminal 20 and the second terminal 30 after the first time.

本申请实施例提供一种发送侧行链路资源的方法，该方法中第一终端可以在确定在第一时刻未向网络设备发送确认信息的情况下，确定用于重新传输侧行链路业务的侧行链路资源，并利用侧行链路资源向第二终端重新发送侧行链路业务，与现有技术 中第一终端未向网络设备发送确认信息的情况下，第一终端并不确定如何处理侧行链路业务相比，可以提高侧行链路数据传输的可靠性。The embodiment of the present application provides a method for sending side-link resources. In the method, the first terminal may determine to retransmit the side-link service when it determines that no confirmation information is sent to the network device at the first moment. And use the side-link resources to resend the side-link service to the second terminal, which is the same as that in the prior art where the first terminal does not send confirmation information to the network device, the first terminal does not Compared with determining how to handle side-link services, the reliability of side-link data transmission can be improved.

参考本申请的另一个实施例，如果用于重新传输所述第一数据包的侧行链路资源由网络设备配置，则如图7所示，本申请实施例提供的方法在步骤602之前，还可以包括：With reference to another embodiment of the present application, if the side link resource used to retransmit the first data packet is configured by the network device, as shown in FIG. 7, the method provided in the embodiment of the present application is before step 602, It can also include:

步骤604、第一终端20接收来自网络设备10的第二侧行链路资源。第二侧行链路资源与第一侧行链路HARQ进程关联。第二侧行链路资源与第一侧行链路HARQ进程关联即第二侧行链路资源对应的进程号与第一侧行链路HARQ进程的进程号相同。Step 604: The first terminal 20 receives the second side link resource from the network device 10. The second side link resource is associated with the first side link HARQ process. The second side link resource is associated with the first side link HARQ process, that is, the process number corresponding to the second side link resource is the same as the process number of the first side link HARQ process.

其中，第二侧行链路资源与第一侧行链路HARQ进程关联，具体为：指示第二侧行链路资源的下行控制信息(down control information，DCI)中包含的HARQ进程号为第一侧行链路HARQ进程的进程号。The second side link resource is associated with the first side link HARQ process, specifically: the HARQ process number included in the downlink control information (DCI) indicating the second side link resource is the first Process ID of the HARQ process on one side of the uplink.

相应的，步骤602具体可以通过以下方式实现：第一终端20确定第二侧行链路资源为第三侧行链路资源。Correspondingly, step 602 may be specifically implemented in the following manner: the first terminal 20 determines that the second side uplink resource is the third side uplink resource.

相应的，本申请实施例中的步骤603具体可以通过以下方式实现：第一终端20在第一时刻之后在第二侧行链路资源上向第二终端30发送第一数据包。Correspondingly, step 603 in the embodiment of the present application may be specifically implemented in the following manner: the first terminal 20 sends the first data packet to the second terminal 30 on the second side uplink resource after the first time.

可以理解的是，当第一终端20需要对第一侧行链路HARQ进程m的第一数据包重传，但是在需要向网络设备10反馈第一侧行链路HARQ进程m的NACK，以便网络设备10根据接收到的NACK确定第一数据包未被正确接收，进而决定是否为第一终端20调度第二侧行链路资源。但是，由于第一终端20在n时刻未向网络设备10反馈第一侧行链路HARQ进程m的NACK，那么第一终端20可以等待网络设备10调度的用于第一侧行链路HARQ进程m的第一数据包重传的第二侧行链路资源(sidelink grant)。当第一终端20接收到该sidelink grant后，第一终端30利用sidelink grant重传第一侧行链路HARQ进程m的第一数据包给第二终端。It is understandable that when the first terminal 20 needs to retransmit the first data packet of the first side uplink HARQ process m, but needs to feed back the NACK of the first side uplink HARQ process m to the network device 10, so that The network device 10 determines that the first data packet is not received correctly according to the received NACK, and then determines whether to schedule the second side uplink resource for the first terminal 20. However, since the first terminal 20 does not feed back the NACK of the first side uplink HARQ process m to the network device 10 at time n, the first terminal 20 can wait for the first side uplink HARQ process scheduled by the network device 10 The second sidelink resource (sidelink grant) for retransmission of the first data packet of m. After the first terminal 20 receives the sidelink grant, the first terminal 30 uses the sidelink grant to retransmit the first data packet of the first side uplink HARQ process m to the second terminal.

如果用于重新传输所述第一数据包的侧行链路资源由第一终端20确定，作为本申请的一种可能的实施例，本申请实施例提供的步骤602具体可以通过以下方式实现：在确认信息指示第二终端30未正确接收第一数据包的情况下，第一终端20将第一侧行链路资源确定为第三侧行链路资源。If the side link resource used to retransmit the first data packet is determined by the first terminal 20, as a possible embodiment of the present application, step 602 provided in the embodiment of the present application can be specifically implemented in the following manner: In the case where the confirmation information indicates that the second terminal 30 did not correctly receive the first data packet, the first terminal 20 determines the first side uplink resource as the third side uplink resource.

其中，第一侧行链路资源可以为网络设备10为第一终端20配置的用于传输第一数据包的侧行链路资源。第一侧行链路资源也可以为第一终端20在预配置的侧行链路资源池中自主选择的侧行链路资源。The first side link resource may be a side link resource configured by the network device 10 for the first terminal 20 to transmit the first data packet. The first side uplink resource may also be a side uplink resource independently selected by the first terminal 20 in a pre-configured side uplink resource pool.

相应的，本申请实施例提供的步骤603具体可以通过以下方式实现：第一终端在第二时刻利用第一侧行链路资源向第二终端发送第一数据包。该第二时刻位于第一时刻之后。Correspondingly, step 603 provided in the embodiment of the present application can be specifically implemented in the following manner: the first terminal uses the first side uplink resource at the second moment to send the first data packet to the second terminal. The second moment is after the first moment.

示例性的，第二时刻由第一时刻和预设偏移值得到。Exemplarily, the second moment is obtained from the first moment and the preset offset value.

示例性的，本申请实施例中的预设偏移值可以为网络设备10向第一终端20配置的，预设偏移值也可以由第一终端20基于预定义协议确定。Exemplarily, the preset offset value in the embodiment of the present application may be configured by the network device 10 to the first terminal 20, and the preset offset value may also be determined by the first terminal 20 based on a predefined protocol.

举例说明，当第一终端20确定需要对第一侧行链路HARQ进程m的第一数据包重传，在n时刻需要向网络设备10反馈第一侧行链路HARQ进程m的NACK，以便网络设备10根据接收到的NACK确定第一数据包未被正确接收，进而决定是否为第 一终端20调度第二侧行链路资源。但是，由于第一终端20在n时刻未向网络设备10反馈第一侧行链路HARQ进程m的NACK，那么第一终端20可以利用前一次传输第一数据包的第一侧行链路资源，在时刻n+X向第二终端30重传第一数据包。其中，X表示预设偏移值，n表示第一时刻。For example, when the first terminal 20 determines that it needs to retransmit the first data packet of the first side uplink HARQ process m, it needs to feed back the NACK of the first side uplink HARQ process m to the network device 10 at time n, so that The network device 10 determines that the first data packet is not received correctly according to the received NACK, and then determines whether to schedule the second side uplink resource for the first terminal 20. However, since the first terminal 20 does not feed back the NACK of the first side uplink HARQ process m to the network device 10 at time n, the first terminal 20 can use the first side uplink resource of the previous transmission of the first data packet , Retransmit the first data packet to the second terminal 30 at time n+X. Among them, X represents the preset offset value, and n represents the first moment.

本申请实施例中第一终端20可以通过预定义协议确定采用第一方式或第二方式确定第三侧行链路资源。当然，第一终端20采用第一方式或第二方式确定侧行链路资源也可以由网络设备10配置。在由网络设备10为第一终端20配置采用第一方式或第二方式确定第三侧行链路资源时，结合图7，本申请实施例提供的方法在步骤601之前还可以包括：In the embodiment of the present application, the first terminal 20 may determine the third side uplink resource in the first manner or the second manner through a predefined protocol. Of course, the first terminal 20 using the first method or the second method to determine the side link resource may also be configured by the network device 10. When the network device 10 configures the first terminal 20 to determine the third side link resource in the first manner or the second manner, with reference to FIG. 7, the method provided in the embodiment of the present application may further include before step 601:

步骤605、网络设备10向第一终端20发送指示信息。该指示信息用于指示第一终端20采用第一方式或第二方式确定侧行链路资源。其中，第一方式为：第一终端20将网络设备10为第一终端20重新分配的第二侧行链路资源确定为第三侧行链路资源。第二方式为：第一终端20将第一侧行链路资源确定为第三侧行链路资源。Step 605: The network device 10 sends instruction information to the first terminal 20. The indication information is used to instruct the first terminal 20 to determine the side link resource in the first manner or the second manner. The first method is: the first terminal 20 determines the second side uplink resource reallocated by the network device 10 for the first terminal 20 as the third side uplink resource. The second way is: the first terminal 20 determines the first side uplink resource as the third side uplink resource.

可以理解的是，第一方式即第一终端20等待网络设备10为第一终端20重新分配第二侧行链路资源，并将第二侧行链路资源确定为第三侧行链路资源。如果被配置为第一方式，则第一终端20和网络设备10提前协商如果第一终端20未向网络设备10发送确认信息，也即网络设备10未接收到确认信息时，网络设备10默认第一数据包未被成功接收，则网络设备便可以确定10需要为第一终端20分配第二侧行链路资源。It can be understood that the first method is that the first terminal 20 waits for the network device 10 to reallocate the second side uplink resource for the first terminal 20, and determines the second side uplink resource as the third side uplink resource . If configured as the first mode, the first terminal 20 and the network device 10 negotiate in advance if the first terminal 20 does not send confirmation information to the network device 10, that is, when the network device 10 does not receive the confirmation information, the network device 10 defaults to the first If a data packet is not successfully received, the network device can determine 10 that the first terminal 20 needs to allocate the second side link resource.

可以理解的是，第二方式即第一终端20在第一时刻之后利用前一次传输第一数据包的第一侧行链路资源重新传输第一数据包。如果被配置为第二方式，则第一终端20和网络设备10提前约定如果第一终端20未向网络设备20发送确认信息时，也即网络设备10未接收到确认信息时，则网络设备10确定无需为第一终端20分配第二侧行链路资源，这样第一终端20可以采用第一侧行链路资源重传第一数据包。It is understandable that the second way is that the first terminal 20 retransmits the first data packet after the first time using the first side link resource of the previous transmission of the first data packet. If configured as the second mode, the first terminal 20 and the network device 10 agree in advance that if the first terminal 20 does not send confirmation information to the network device 20, that is, when the network device 10 does not receive the confirmation information, the network device 10 It is determined that there is no need to allocate the second side uplink resource for the first terminal 20, so that the first terminal 20 can use the first side uplink resource to retransmit the first data packet.

步骤606、第一终端20接收来自网络设备10的指示信息。Step 606: The first terminal 20 receives the instruction information from the network device 10.

相应的，第一终端20根据指示信息，确定采用第一方式或第二方式确定侧行链路资源。Correspondingly, the first terminal 20 determines to use the first method or the second method to determine the side link resource according to the instruction information.

需要说明的是，如果第一终端20和网络设备10提前协商好采用第一方式或第二方式确定侧行链路资源，则步骤605和步骤606可以省略。也即步骤605和步骤606为可选的步骤。It should be noted that if the first terminal 20 and the network device 10 negotiate in advance to determine the side link resource in the first way or the second way, step 605 and step 606 can be omitted. That is, step 605 and step 606 are optional steps.

可以理解的是，本申请实施例中图4或图5所描述的方案可以和图6和图7所描述的方案作为一个完整方案实施，当然图4或图5所描述的方案可以作为一个方案实施，用于描述在第一终端20未向网络设备10发送确认信息的情况下，以及确认信息指示第一数据包被正确接收时，且网络设备10重新为第一终端20调度了第二侧行链路资源的情况下，第一终端20如何处理第二侧行链路资源。图6和图7所描述的方案作为一个方案实施，用于描述在第一终端20未向网络设备10发送确认信息的情况下，以及确认信息指示第一数据包未被正确接收时，第一终端20通过重新确定用于重新传输的侧行链路资源，以向第二终端30重新传输第一数据包。It is understandable that the solution described in FIG. 4 or FIG. 5 in the embodiments of the present application can be implemented as a complete solution with the solution described in FIG. 6 and FIG. 7, of course, the solution described in FIG. 4 or FIG. 5 can be used as a solution.

Wherein, the HARQ parameter of the second side uplink resource includes NDI.

图8所述的方案适用于第一终端20向网络设备10发送第一侧行链路HARQ进程的确认信息，但是网络设备10未接收到确认信息，又为第一终端20分配第二侧行链路资源的情况。The solution described in FIG. 8 is suitable for the first terminal 20 to send confirmation information of the first side link HARQ process to the network device 10, but the network device 10 does not receive the confirmation information, and allocates the second side link to the first terminal 20.

比如说，第一终端根据第二侧行链路资源的HARQ参数，在第二侧行链路资源上传输第二数据包，包括：在NDI指示新传，且HARQ进程号为第一侧行链路HARQ进程的进程号，且第一变量的值为第一参数值的情况下，第一终端在第二侧行链路资源上传输第二数据包。For example, the first terminal transmits the second data packet on the second side uplink resource according to the HARQ parameters of the second side uplink resource, including: indicating a new transmission in the NDI, and the HARQ process number is the first side row When the process number of the link HARQ process and the value of the first variable is the first parameter value, the first terminal transmits the second data packet on the second side uplink resource.

比如说，步骤801具体可以通过以下方式实现：第一终端20确定发送确认信息的时刻与第一终端20发送第一消息的时刻均为第一时刻。在承载确认信息的物理上行信道的优先级高于第一消息的优先级，或者承载确认信息的物理上行信道的优先级高于承载所述第一消息的侧行链路信道的优先级的情况下，第一终端20确定在第一时刻20向网络设备10发送确认信息。For example, step 801 may be specifically implemented in the following manner: the first terminal 20 determines that the time when the confirmation information is sent and the time when the first terminal 20 sends the first message are both the first time. When the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the first message, or the priority of the physical uplink channel carrying the confirmation information is higher than the priority of the side link channel carrying the first message Next, the first terminal 20 determines to send confirmation information to the network device 10 at the first time 20.

比如说，第一消息为第一终端20在随机接入过程中向网络设备10发送的消息。For example, the first message is a message sent by the first terminal 20 to the network device 10 during the random access process.

比如说，物理上行信道为物理上行控制信道，第一消息为侧行链路SL媒体接入控制MAC协议数据单元PDU，承载第一消息的侧行链路信道为侧行链路共享信道SL-SCH，第一终端根据承载确认信息的物理上行信道的优先级、以及承载第一消息的侧行链路信道的优先级，确定在第一时刻向网络设备发送确认信息，包括：在第一时刻承载确认信息的物理上行控制信道的优先级高于侧行链路共享信道所映射的物理侧行链路共享信道PSSCH的优先级的情况下，第一终端确定在第一时刻向网络设备发送确认信息。For example, the physical uplink channel is a physical uplink control channel, the first message is a side link SL media access control MAC protocol data unit PDU, and the side link channel carrying the first message is a side link shared channel SL- SCH, the first terminal determines to send the confirmation information to the network device at the first moment according to the priority of the physical uplink channel carrying the confirmation information and the priority of the side link channel carrying the first message, including: In the case where the priority of the physical uplink control channel carrying the confirmation information is higher than the priority of the physical side link shared channel PSSCH mapped by the side link shared channel, the first terminal determines to send the confirmation to the network device at the first moment information.

比如说，确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级高于在SL-SCH上传输的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级，第一终端确定承载确认信息的物理上行控制信道的优先级高于承载SL MAC PDU的SL-SCH所映射的PSSCH的优先级。For example, the priority of the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation message is higher than the priority of the side link logical channel with the highest priority in the SL MAC PDU transmitted on the SL-SCH The first terminal determines that the priority of the physical uplink control channel carrying the confirmation information is higher than the priority of the PSSCH mapped to the SL-SCH carrying the SL MAC PDU.

比如说，物理上行信道为物理上行共享信道PUSCH，第一消息为侧行链路SL媒 体接入控制MAC协议数据单元PDU，承载第一消息的侧行链路信道为侧行链路共享信道SL-SCH。第一终端根据承载确认信息的上行信道的优先级、以及承载第一消息的侧行链路信道的优先级，确定在第一时刻向网络设备发送确认信息，包括：如果PUSCH的优先级高于SL-SCH的优先级，第一终端确定在第一时刻向网络设备发送确认信息。For example, the physical uplink channel is the physical uplink shared channel PUSCH, the first message is the side link SL media access control MAC protocol data unit PDU, and the side link channel carrying the first message is the side link shared channel SL -SCH. The first terminal determines to send confirmation information to the network device at the first moment according to the priority of the uplink channel carrying the confirmation information and the priority of the side link channel carrying the first message, including: if the priority of the PUSCH is higher than For the priority of SL-SCH, the first terminal determines to send confirmation information to the network device at the first moment.

比如说，如果在所述PUSCH上传输的MAC PDU中优先级最高的上行链路逻辑信道的优先级高于在SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级，则第一终端确定PUSCH的优先级高于SL-SCH的优先级。For example, if the priority of the uplink logical channel with the highest priority in the MAC PDU transmitted on the PUSCH is higher than the priority of the side link logical channel with the highest priority in the MAC PDU transmitted on the SL-SCH Level, the first terminal determines that the priority of the PUSCH is higher than the priority of the SL-SCH.

比如说，如果确认信息对应的SL MAC PDU中优先级最高的侧行链路逻辑信道的优先级，和在PUSCH上传输的MAC PDU中优先最高的上行链路逻辑信道的优先级均高于在SL-SCH上传输的MAC PDU中优先级最高的侧行链路逻辑信道的优先级，则第一终端确定PUSCH的优先级高于SL-SCH的优先级。For example, if the priority of the side link logical channel with the highest priority in the SL MAC PDU corresponding to the confirmation message, and the priority of the uplink logical channel with the highest priority in the MAC PDU transmitted on the PUSCH, the priority The priority of the side link logical channel with the highest priority among the MAC PDUs transmitted on the SL-SCH, the first terminal determines that the priority of the PUSCH is higher than the priority of the SL-SCH.
