具体实施方式Detailed ways

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。针对本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, not all of the embodiments. Regarding the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

本申请实施例可以适用于任何终端设备到终端设备的通信框架。The embodiments of the present application can be applied to any terminal device-to-terminal device communication framework.

例如，车辆到车辆(Vehicle to Vehicle，V2V)、车辆到其他设备(Vehicle to Everything，V2X)、终端到终端(Device to Device，D2D)等。For example, vehicle to vehicle (Vehicle to Vehicle, V2V), vehicle to other device (Vehicle to Everything, V2X), terminal to terminal (Device to Device, D2D), and so on.

其中，本申请实施例中的终端可以是任何配置有物理层和媒体接入控制层的设备或装置，终端设备也可称为接入终端。例如，用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字线性处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它线性处理设备、车载设备、可穿戴设备等等。本申请实施例以车载终端为例进行说明，但并不限于此。Wherein, the terminal in the embodiment of the present application may be any device or device configured with a physical layer and a media access control layer, and the terminal device may also be referred to as an access terminal. For example, User Equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital linear processing (Personal Digital Assistant, PDA), and a wireless Communication-enabled handheld devices, computing devices, or other linear processing devices connected to wireless modems, in-vehicle devices, wearable devices, etc. The embodiment of the present application takes a vehicle-mounted terminal as an example for description, but is not limited to this.

第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)定义了两种传输模式，分别记为：模式A和模式B。The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) defines two transmission modes, which are respectively denoted as Mode A and Mode B.

图1是本申请实施例的模式A的示意图。图2是本申请实施例的模式B的示意图。Fig. 1 is a schematic diagram of mode A of an embodiment of the present application. Fig. 2 is a schematic diagram of mode B of an embodiment of the present application.

在图1所示的模式A中，车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的，车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地，基站110可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。In the mode A shown in FIG. 1, the transmission resources of the vehicle-mounted terminal (vehicle terminal 121 and the vehicle-mounted terminal 122) are allocated by the base station 110, and the vehicle-mounted terminal transmits data on the side link according to the resources allocated by the base station 110. Specifically, the base station 110 may allocate resources for a single transmission to the terminal, or allocate resources for semi-static transmission to the terminal.

在图2所示的模式B中，车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地，车载终端可以随机选取传输资源，或者通过侦听的方式选取传输资源。In the mode B shown in FIG. 2, the vehicle-mounted terminal (the vehicle-mounted terminal 131 and the vehicle-mounted terminal 132) autonomously selects transmission resources for data transmission on the resources of the side link. Optionally, the vehicle-mounted terminal can select the transmission resource randomly, or select the transmission resource by means of interception.

下面以车载终端131为例进行具体说明。The following takes the vehicle-mounted terminal 131 as an example for specific description.

车载终端131在资源池中通过侦听的方式获取可用的传输资源集合，车载终端131从该集合中随机选取一个传输资源进行数据的传输。The vehicle-mounted terminal 131 obtains a set of available transmission resources in the resource pool by means of interception, and the vehicle-mounted terminal 131 randomly selects a transmission resource from the set for data transmission.

由于车联网***中的业务具有周期性特征，本申请实施例中，车载终端131还可以采用半静态传输的方式。即车载终端131获取一个传输资源后，在多个传输周期中持续的使用该传输资源，以降低资源重选以及资源冲突的概率。Since the services in the Internet of Vehicles system have periodic characteristics, in the embodiment of the present application, the vehicle-mounted terminal 131 may also adopt a semi-static transmission mode. That is, after acquiring a transmission resource, the vehicle-mounted terminal 131 continuously uses the transmission resource in multiple transmission periods to reduce the probability of resource reselection and resource conflict.

车载终端131可以在本次传输的控制信息中携带预留下次传输资源的信息，使得其他终端(例如，车载终端132)可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。The vehicle-mounted terminal 131 can carry information for reserving resources for the next transmission in the control information of this transmission, so that other terminals (for example, the vehicle-mounted terminal 132) can determine whether this resource is reserved by the user by detecting the control information of the user. And use, to achieve the purpose of reducing resource conflicts.

需要说明的是，在新无线(New Radio，NR)车辆到其他设备(Vehicle to Everything，V2X)中，用户可能处在一个混合的模式下，即既可以使用模式A进行资源的获取，又同时可以使用模式B进行资源的获取。It should be noted that in the New Radio (NR) vehicle to other equipment (Vehicle to Everything, V2X), the user may be in a mixed mode, that is, mode A can be used for resource acquisition, and at the same time You can use mode B for resource acquisition.

在NR-V2X中，引入了单播和组播的传输方式。对于单播传输，其接收端终端只有一个终端，如图3中，UE 1、UE 2之间进行单播传输；对于组播传输，其接收端是一个通信组内的所有终端，或者是在一定传输距离内的所有终端，如图4，UE 1、UE 2、UE 3和UE 4构成一个通信组，其中UE 1发送数据，该组内的其他终端设备都是接收端终端；对于广播传输方式，其接收端是任意一个终端，如图5，其中UE 1是发送端终端，其周围的其他终端都是接收端终端。In NR-V2X, unicast and multicast transmission methods are introduced. For unicast transmission, the receiving end has only one terminal, as shown in Figure 3, unicast transmission is performed between UE1 and UE2; for multicast transmission, the receiving end is all terminals in a communication group, or All terminals within a certain transmission distance, as shown in Figure 4, UE1, UE2, UE3, and UE4 form a communication group, where UE1 sends data, and other terminal devices in the group are receiving end terminals; for broadcast transmission In this way, the receiving end is any terminal, as shown in Figure 5, where UE 1 is the transmitting end terminal, and the other terminals around it are all receiving end terminals.

在NR-V2X中，为了提高可靠性，引入了侧行反馈信道。例如，如图6所示，对于单播传输，发送端终端向接收端终端发送侧行数据(包括物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)和物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH))，接收端终端向发送端终端发送混合自动请求重传(Hybrid Automatic Repeat reQuest，HARQ)反馈信息，发送端终端根据接收端终端的反馈信息判断是否需要进行重传。其中，HARQ反馈信息承载在侧行反馈信道中，例如物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)。In NR-V2X, in order to improve reliability, a side-line feedback channel is introduced. For example, as shown in Figure 6, for unicast transmission, the sender terminal sends sideline data (including Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel) to the receiver terminal. , PSSCH)), the receiving end terminal sends Hybrid Automatic Repeat reQuest (HARQ) feedback information to the transmitting end terminal, and the transmitting end terminal determines whether retransmission is required according to the feedback information of the receiving end terminal. Among them, HARQ feedback information is carried in a side-line feedback channel, such as a physical side-link feedback channel (PSFCH).

可以通过预配置信息或者网络配置信息激活或者去激活侧行反馈，如果侧行(Sidelink，SL)反馈被激活，则接收端终端接收发送端终端发送的侧行数据，并且根据检测结果向发送端反馈HARQ肯定应答(Acknowledgement，ACK)或者否定应答(Negative Acknowledgement，NACK)，发送端终端根据接收端的反馈信息决定发送重传数据或者新数据；如果侧行反馈被去激活，接收端终端不需要发送反馈信息，发送端终端通常采用盲重传的方式发送数据，例如，发送端终端对每个侧行数据重复发送K次，而不是根据接收端终端反馈信息决定是否需要发送重传数据。The side-line feedback can be activated or deactivated through pre-configuration information or network configuration information. If the side-line (Sidelink, SL) feedback is activated, the receiving end terminal receives the side-line data sent by the sending end terminal, and sends it to the sending end according to the detection result. When the HARQ acknowledgement (Acknowledgement, ACK) or negative acknowledgement (Negative Acknowledgement, NACK) is fed back, the sender terminal decides to send retransmission data or new data according to the feedback information of the receiver; if the sideline feedback is deactivated, the receiver terminal does not need to send For feedback information, the sending end terminal usually sends data in a blind retransmission manner. For example, the sending end terminal repeatedly sends K times for each side row data, instead of deciding whether to send retransmission data based on the feedback information of the receiving end terminal.

在NR-V2X中，可以采用盲重传的方式传输侧行数据，即发送端设备不需要接收端设备的反馈，自主决定进行重传。另外，在NR-V2X中，引入了侧行反馈，因此发送端设备可以根据接收端设备的反馈决定是否需要进行重传，如果接收端设备反馈ACK，则发送端设备停止重传；如果接收端设备反馈NACK，则发送端设备进行重传。In NR-V2X, blind retransmission can be used to transmit side-line data, that is, the sending end device does not need feedback from the receiving end device and independently decides to retransmit. In addition, in NR-V2X, side-line feedback is introduced, so the sender device can decide whether to retransmit according to the feedback of the receiver device. If the receiver device feedbacks ACK, the sender device stops retransmission; if the receiver device feedbacks ACK, the sender device stops retransmission; The device feeds back NACK, and the sender device performs retransmission.

在基于侧行反馈的传输中，发送端设备发送侧行数据，接收端设备根据接收到的数据的检测情况向发送端设备发送侧行反馈信息，发送端设备根据接收端设备的反馈信息决定是否进行重传，即一个侧行数据的传输对应一个侧行反馈，如图7所示，发送端设备在一个侧行传输资源(如图中PSCCH+PSSCH #1)上传输侧行数据，接收端设备在一个侧行反馈资源(如图中PSFCH #1)上传输侧行反馈，如果接收端反馈的是NACK，则发送端设备在另一个侧行传输资源(如图中PSCCH+PSSCH #2)上重传该侧行数据，如果接收端反馈的是ACK，则发送端设备在PSCCH+PSSCH #2上传输新的侧行数据，接收端设备在另一个侧行反馈资源(如图中PSFCH #2)上传输侧行反馈。In transmission based on sideline feedback, the sender device sends sideline data, the receiver device sends sideline feedback information to the sender device based on the detection of the received data, and the sender device decides whether or not according to the feedback information of the receiver device. Retransmission is performed, that is, the transmission of one side line data corresponds to one side line feedback. As shown in Figure 7, the sending end device transmits the side line data on a side line transmission resource (PSCCH+PSSCH #1 in the figure), and the receiving end The device transmits the side-line feedback on one side-line feedback resource (PSFCH#1 in the figure). If the receiving end feeds back NACK, the sending-end device transmits the resource on the other side-line (PSCCH+PSSCH#2 in the picture). The side line data is retransmitted on the upper side. If the receiving end feeds back an ACK, the sending end device transmits the new side line data on PSCCH+PSSCH #2, and the receiving end device feeds back resources on the other side line (PSFCH# in the figure). 2) Upper transmission side line feedback.

在某些情况下，如发送端设备待发送的侧行数据的时延要求很高，如<5ms，则发送端设备通常需要在尽可能短的时间将侧行数据发送出去，此时如果根据接收端设备的反馈决定重传会导致额外的时延，因此，可以采用盲重传和基于侧行反馈重传结合的方式，如下图8所示，发送端设备在PSCCH+PSSCH #1上传输侧行数据，在PSCCH+PSSCH #2上传输该侧行数据的重传数据，接收端设备在PSFCH上传输侧行反馈。In some cases, such as the side line data to be sent by the sender device has a very high latency requirement, such as <5ms, the sender device usually needs to send the side line data in the shortest possible time. The feedback of the receiving device determines that the retransmission will cause additional delay. Therefore, a combination of blind retransmission and retransmission based on side row feedback can be used. As shown in Figure 8 below, the transmitting device transmits on PSCCH+PSSCH#1 For side-line data, the retransmission data of the side-line data is transmitted on PSCCH+PSSCH#2, and the receiving end device transmits the side-line feedback on the PSFCH.

如图8所示，发送端设备在接收到侧行反馈之前，对侧行数据发送了两次，从而可以尽快的将侧行数据发送出去，并且通过两次传输提高了传输可靠性。但是，如果所有的传输都采用这样的方式发送侧行数据，就会导致***的资源变得拥塞，提高传输碰撞的概率，从而降低***的性能。例如，如果终端设备在第一次发送的时候接收端设备就已经正确接收了数据，则发送端设备不需要发送重传，从而可以降低资源利用率，也可以降低终端设备之间的传输冲突。As shown in Figure 8, the sending end device sends the side row data twice before receiving the side row feedback, so that the side row data can be sent out as quickly as possible, and the transmission reliability is improved through two transmissions. However, if all transmissions use this method to send sideline data, it will cause system resources to become congested, increase the probability of transmission collisions, and reduce system performance. For example, if the receiving end device has correctly received the data when the terminal device transmits for the first time, the transmitting end device does not need to send retransmissions, which can reduce resource utilization and reduce transmission conflicts between terminal devices.

基于上述技术问题，本申请设计了一种侧行重传方案，终端设备可以在接收到侧行反馈之前自主决定进行重传从而可以保证侧行数据的时延需求、可靠性需求等。Based on the above technical problems, the present application designs a side-line retransmission scheme. The terminal device can independently decide to retransmit before receiving the side-line feedback so as to ensure the delay requirements and reliability requirements of the side-line data.

图9是本申请实施例的无线通信方法200的示意性流程图。该方法200可以由终端设备执行。图9中所示的终端设备可以是如图1至图8中任一所示的车载终端。FIG. 9 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. The method 200 may be executed by a terminal device. The terminal device shown in FIG. 9 may be a vehicle-mounted terminal as shown in any one of FIGS. 1 to 8.

如图9所示，该方法200可以包括如下内容中的部分或者全部：As shown in FIG. 9, the method 200 may include some or all of the following contents:

S210，终端设备确定在接收到针对第一侧行数据的侧行反馈之前是否进行针对该第一侧行数据的重传。S210: The terminal device determines whether to retransmit the first side row data before receiving the side row feedback for the first side row data.

需要说明的是，在接收到侧行反馈之前的重传可以是盲重传。以及在接收到侧行反馈之前终端设备可以自主决定是否进行重传。It should be noted that the retransmission before the side row feedback is received may be blind retransmission. And before receiving the side-line feedback, the terminal device can independently decide whether to retransmit.

可选地，在上述步骤S210之前，该终端设备传输该第一侧行数据，具体的，可以包括初传或者重传该第一侧行数据。Optionally, before step S210, the terminal device transmits the first side row data, specifically, it may include initial transmission or retransmission of the first side row data.

应理解，该侧行反馈时针对该第一侧行数据的反馈，如该侧行反馈是ACK或NACK，用于指示该第一侧行数据是否被正确接收。It should be understood that the feedback for the first side row data during the side row feedback, if the side row feedback is ACK or NACK, is used to indicate whether the first side row data is received correctly.

可选地，终端设备可以通过单播，组播，广播等方式初传或者重传该第一侧行数据。Optionally, the terminal device may initially transmit or retransmit the first side row data by means of unicast, multicast, broadcast, or the like.

在本申请实施例中，若该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传，该终端设备在接收到该侧行反馈之前进行针对该第一侧行数据的重传。In the embodiment of the present application, if the terminal device determines to retransmit the first side row data before receiving the side row feedback, the terminal device performs the retransmission for the first side row before receiving the side row feedback. Retransmission of data.

可选地，在本申请实施例中，该终端设备接收该侧行反馈；以及该终端设备根据该侧行反馈确定是否进行针对该第一侧行数据的重传。Optionally, in this embodiment of the present application, the terminal device receives the sideline feedback; and the terminal device determines whether to retransmit the first sideline data according to the sideline feedback.

可选地，作为示例1，上述步骤S210具体可以是：Optionally, as example 1, the foregoing step S210 may specifically be:

该终端设备根据第一信息确定在接收到该侧行反馈之前是否进行针对该第一侧行数据的重传，其中，该第一信息包括以下中的至少一种：The terminal device determines whether to retransmit the first side row data before receiving the side row feedback according to the first information, where the first information includes at least one of the following:

该第一侧行数据的优先级、传输该第一侧行数据的时延需求、信道繁忙比率(Channel Busy Ratio，CBR)。The priority of the first side row data, the delay requirement for transmitting the first side row data, and the channel busy ratio (CBR).

需要说明的是，上述CBR可以是***的CBR，或传输该第一侧行数据所在的资源池的CBR。也就是说，若该第一信息包括CBR，该终端设备需要测量***的CBR或资源池的CBR。It should be noted that the foregoing CBR may be the CBR of the system or the CBR of the resource pool where the first side row data is transmitted. That is, if the first information includes CBR, the terminal device needs to measure the CBR of the system or the CBR of the resource pool.

应理解，CBR是用来衡量***资源占用情况的一个测量量，CBR越高，表示***资源被占用的越多，终端设备选取传输资源时，跟其他用户的传输发生碰撞的概率越高；CBR越低，表示***资源被占用的越少，终端设备选取传输资源时，跟其他用户的传输发生碰撞的概率越低。因此，在CBR很高时，尽量降低资源使用率，从而降低***的CBR，达到降低用户之间干扰、冲突的目的。It should be understood that CBR is a measurement used to measure the occupancy of system resources. The higher the CBR, the more system resources are occupied. When the terminal device selects transmission resources, the higher the probability of collisions with other users' transmissions; CBR The lower the value, the less system resources are occupied, and the lower the probability of collisions with other users' transmissions when the terminal device selects transmission resources. Therefore, when the CBR is high, try to reduce the resource utilization rate, thereby reducing the CBR of the system, and achieving the purpose of reducing interference and conflicts between users.

可选地，在示例1中，该第一侧行数据的优先级承载于针对该第一侧行数据的侧行控制信息(Sidelink Control Information，SCI)中，即该SCI用于指示该第一侧行数据的传输资源、传输参数等。Optionally, in Example 1, the priority of the first side row data is carried in the side link control information (SCI) for the first side row data, that is, the SCI is used to indicate the first side row data. Transmission resources, transmission parameters, etc. of side-line data.

例如，该第一侧行数据的优先级可以是优先级等级，对应0-7，优先级等级取值越高，其对应的优先级越低。假设数据1的优先级等级为0，数据2的优先级等级为1，则数据1的优先级高于数据2。For example, the priority of the first side row data may be a priority level, corresponding to 0-7, the higher the priority level is, the lower the corresponding priority is. Assuming that the priority level of data 1 is 0 and the priority level of data 2 is 1, then the priority of data 1 is higher than that of data 2.

可选地，在示例1中，该终端设备可以基于该第一信息所包括的一种信息确定在接收到该侧行反馈之前是否进行针对该第一侧行数据的重传。Optionally, in Example 1, the terminal device may determine whether to retransmit the first side row data before receiving the side row feedback based on a type of information included in the first information.

可选地，假设该第一信息包括该第一侧行数据的优先级，具体地：Optionally, it is assumed that the first information includes the priority of the first side row data, specifically:

若该第一侧行数据的优先级高于第一阈值，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传；或者，If the priority of the first side line data is higher than the first threshold, the terminal device determines to retransmit the first side line data before receiving the side line feedback; or,

若该第一侧行数据的优先级低于或者等于第一阈值，该终端设备确定在接收到该侧行反馈之前不进行针对该第一侧行数据的重传。If the priority of the first side row data is lower than or equal to the first threshold, the terminal device determines not to retransmit the first side row data before receiving the side row feedback.

可选地，假设该第一信息包括传输该第一侧行数据的时延需求，具体地：Optionally, it is assumed that the first information includes a delay requirement for transmitting the first side line data, specifically:

若传输该第一侧行数据的时延需求低于第二阈值，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传；或者，If the delay requirement for transmitting the first side line data is lower than the second threshold, the terminal device determines to retransmit the first side line data before receiving the side line feedback; or,

若传输该第一侧行数据的时延需求高于或者等于第二阈值，该终端设备确定在接收到该侧行反馈之前不进行针对该第一侧行数据的重传。If the delay requirement for transmitting the first side line data is higher than or equal to the second threshold, the terminal device determines not to retransmit the first side line data before receiving the side line feedback.

例如，该第一侧行数据的时延需求是10ms，第二阈值是20ms，则该终端设备在接收到该侧行反馈之前可以自主进行针对该第一侧行数据的重传。For example, if the delay requirement of the first side line data is 10 ms and the second threshold is 20 ms, the terminal device can autonomously retransmit the first side line data before receiving the side line feedback.

例如，该第一侧行数据的时延需求是50ms，第二阈值是20ms，则该终端设备在接收到该侧行反馈之前不能自主进行针对该第一侧行数据的重传。For example, if the delay requirement of the first side line data is 50 ms and the second threshold is 20 ms, the terminal device cannot automatically retransmit the first side line data before receiving the side line feedback.

可选地，假设该第一信息包括CBR，具体地：Optionally, it is assumed that the first information includes CBR, specifically:

若CBR低于第三阈值，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传；或者，If the CBR is lower than the third threshold, the terminal device determines to retransmit the first side row data before receiving the side row feedback; or,

若CBR高于或者等于第三阈值，该终端设备确定在接收到该侧行反馈之前不进行针对该第一侧行数据的重传。If the CBR is higher than or equal to the third threshold, the terminal device determines not to retransmit the first side row data before receiving the side row feedback.

需要说明的是，如果***的CBR很低，则终端设备可以在接收到侧行反馈之前自主决定进行重传，此时发生传输冲突的概率低；但是当CBR很高时，如果终端设备在接收到侧行反馈之前自主进行重传，就会导致***资源利用率提高，也提高了传输冲突的概率。因此，当CBR高于或者等于第三阈值时，不支持终端设备自主进行重传。It should be noted that if the CBR of the system is very low, the terminal device can independently decide to retransmit before receiving the side line feedback. At this time, the probability of transmission conflict is low; but when the CBR is high, if the terminal device is receiving Autonomous retransmission before side-line feedback will lead to an increase in system resource utilization and increase the probability of transmission conflict. Therefore, when the CBR is higher than or equal to the third threshold, the terminal device does not support autonomous retransmission.

可选地，在示例1中，该终端设备可以基于该第一信息所包括的至少两种信息确定在接收到该侧行反馈之前是否进行针对该第一侧行数据的重传。具体地，该终端设备可以执行以下中的至少两种：Optionally, in Example 1, the terminal device may determine whether to retransmit the first side row data before receiving the side row feedback based on at least two types of information included in the first information. Specifically, the terminal device can perform at least two of the following:

若该第一侧行数据的优先级高于第一阈值，并且CBR低于第三阈值，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传，否则，该终端设备确定在接收到该侧行反馈之前不进行针对该第一侧行数据的重传；If the priority of the first side line data is higher than the first threshold, and the CBR is lower than the third threshold, the terminal device determines to retransmit the first side line data before receiving the side line feedback; otherwise, The terminal device determines not to retransmit the first side row data before receiving the side row feedback;

若传输该第一侧行数据的时延需求低于第二阈值，并且CBR低于第三阈值，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传，否则，该终端设备确定在接收到该侧行反馈之前不进行针对该第一侧行数据的重传；If the delay requirement for transmitting the first side line data is lower than the second threshold, and the CBR is lower than the third threshold, the terminal device determines to retransmit the first side line data before receiving the side line feedback, Otherwise, the terminal device determines not to retransmit the first side row data before receiving the side row feedback;

若该第一侧行数据的优先级高于第一阈值，并且传输该第一侧行数据的时延需求低于第二阈值，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传，否则，该终端设备确定在接收到该侧行反馈之前不进行针对该第一侧行数据的重传。If the priority of the first side line data is higher than the first threshold, and the delay requirement for transmitting the first side line data is lower than the second threshold, the terminal device determines to perform a response to the first side line before receiving the side line feedback. Retransmission of the side line data; otherwise, the terminal device determines not to retransmit the first side line data before receiving the side line feedback.

例如，在该第一侧行数据的优先级高于第一阈值且CBR低于第三阈值的情况下，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传。For example, in the case where the priority of the first side row data is higher than the first threshold and the CBR is lower than the third threshold, the terminal device determines to perform reconfiguration on the first side row data before receiving the side row feedback. pass.

又例如，在传输该第一侧行数据的时延需求低于第二阈值且CBR低于第三阈值的情况下，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传。For another example, in the case that the delay requirement for transmitting the first side line data is lower than the second threshold and the CBR is lower than the third threshold, the terminal device determines to perform a response to the first side line before receiving the side line feedback. Retransmission of data.

再例如，在该第一侧行数据的优先级高于第一阈值且传输该第一侧行数据的时延需求低于第二阈值的情况下，该终端设备确定在接收到该侧行反馈之前进行针对该第一侧行数据的重传。For another example, in the case that the priority of the first side line data is higher than the first threshold and the delay requirement for transmitting the first side line data is lower than the second threshold, the terminal device determines to receive the side line feedback The retransmission for the first side row data was previously performed.

可选地，在示例1中，该第一阈值、该第二阈值、该第三阈值中的至少一种为预配置的或者为网络设备配置的。Optionally, in Example 1, at least one of the first threshold, the second threshold, and the third threshold is pre-configured or configured for a network device.

可选地，在示例1中，该终端设备获取资源池配置信息，该资源池配置信息中包括该第一阈值、该第二阈值、该第三阈值中的至少一种。Optionally, in Example 1, the terminal device obtains resource pool configuration information, and the resource pool configuration information includes at least one of the first threshold, the second threshold, and the third threshold.

需要说明的是，在本申请实施例中，终端设备确定在接收到针对第一侧行数据的侧行反馈之前进行针对该第一侧行数据的重传，表示终端设备可以进行针对该第一侧行数据的重传，并不代表该终端设备一定进行针对该第一侧行数据的重传。例如，如图10所示，侧行反馈资源的时域周期是4，即每4个时隙包括一个侧行反馈的时隙，时隙0-3的侧行数据，其对应的侧行反馈信息在时隙5进行传输。如果终端设备待发送的侧行数据的优先级等级是3，第一阈值时5，即终端设备可以在接收到侧行反馈之前发送重传，则该终端设备可以选取时隙0和时隙3的传输资源，在时隙0发送该侧行数据的首次传输，在时隙3发送该侧行数据的重传，并且在时隙5接收该侧行数据的反馈信息。可选地，该终端设备也可以在时隙0至时隙3只选取一个传输资源，如选择时隙0的传输资源，在该传输资源上发送该侧行数据的首次传输，在时隙5接收该侧行数据的反馈信息，并且根据该侧行反馈信息决定是否进行重传。It should be noted that in this embodiment of the application, the terminal device determines to retransmit the first side row data before receiving the side row feedback for the first side row data, which means that the terminal device can perform the retransmission for the first side row data. The retransmission of the side row data does not mean that the terminal device must retransmit the first side row data. For example, as shown in Figure 10, the time domain period of the side-line feedback resource is 4, that is, every 4 time slots includes a side-line feedback time slot, and the side-line data of time slots 0-3 corresponds to the side-line feedback Information is transmitted in time slot 5. If the priority level of the sideline data to be sent by the terminal device is 3, and the first threshold is 5, that is, the terminal device can send retransmissions before receiving the sideline feedback, then the terminal device can select time slot 0 and time slot 3 The first transmission of the side row data is sent in time slot 0, the retransmission of the side row data is sent in time slot 3, and the feedback information of the side row data is received in time slot 5. Optionally, the terminal device can also select only one transmission resource from time slot 0 to time slot 3, for example, select the transmission resource of time slot 0, and send the first transmission of the side row data on the transmission resource, in time slot 5 Receive the feedback information of the side line data, and decide whether to retransmit according to the side line feedback information.

可选地，作为示例2，上述步骤S210具体可以是：Optionally, as example 2, the foregoing step S210 may specifically be:

该终端设备接收网络设备发送的配置信息；以及该终端设备根据该配置信息确定在接收到该侧行反馈之前是否进行针对该第一侧行数据的重传。The terminal device receives the configuration information sent by the network device; and the terminal device determines, according to the configuration information, whether to retransmit the first side row data before receiving the side row feedback.

可选地，在示例2中，该配置信息通过配置该第一侧行数据的传输资源指示该终端设备在接收到该侧行反馈之前是否进行针对该第一侧行数据的重传。Optionally, in Example 2, the configuration information indicates whether the terminal device retransmits the first side row data before receiving the side row feedback by configuring the transmission resource of the first side row data.

可选地，在示例2中，该配置信息为以下中的一种：Optionally, in Example 2, the configuration information is one of the following:

广播信息、无线资源控制(Radio Resource Control，RRC)信令、下行控制信息(Downlink Control Information，DCI)信令。Broadcast information, Radio Resource Control (RRC) signaling, and Downlink Control Information (DCI) signaling.

可选地，在示例2中，该终端设备向该网络设备发送第二信息，其中，该第二信息包括以下中的至少一种：Optionally, in Example 2, the terminal device sends second information to the network device, where the second information includes at least one of the following:

该第一侧行数据的优先级、传输该第一侧行数据的时延需求、CBR。The priority of the first side row data, the delay requirement for transmitting the first side row data, and CBR.

可选地，该终端设备在终端辅助信息(UEAssistanceInformation)中携带指示信息，该指示信息用于确定该第二信息。Optionally, the terminal device carries indication information in terminal assistance information (UEAssistanceInformation), and the indication information is used to determine the second information.

具体地，该网络设备可以基于该第二信息，确定该配置信息。也即，该终端设备先向该网络设备发送该第二信息，然后，该终端设备接收该网络设备发送的该配置信息。Specifically, the network device may determine the configuration information based on the second information. That is, the terminal device first sends the second information to the network device, and then the terminal device receives the configuration information sent by the network device.

需要说明的是，侧行传输资源可以是网络设备分配的，如网络设备通过动态授权或者配置授权的方式为终端设备分配侧行传输资源，终端设备在向网络设备申请传输资源时，可以向网络设备发送辅助信息(第二信息)，该辅助信息例如可以包括待传输数据的优先级信息、时延信息等，终端设备也可以将测量的CBR上报给网络设备，因此，网络设备可以根据这些信息配置终端设备是否可以在接收到侧行反馈信息之前进行数据重传。It should be noted that the side transmission resources can be allocated by the network equipment. For example, the network equipment allocates the side transmission resources to the terminal equipment by means of dynamic authorization or configuration authorization. The terminal equipment can apply to the network for transmission resources when applying for transmission resources from the network equipment. The device sends auxiliary information (second information). The auxiliary information may include, for example, priority information and delay information of the data to be transmitted. The terminal device can also report the measured CBR to the network device. Therefore, the network device can use this information Configure whether the terminal device can retransmit data before receiving the side-line feedback information.

可选地，在示例2中，例如，如果侧行反馈资源的时域周期是4，即每4个时隙包括一个侧行反馈的时隙，如图10所示，时隙0-3的侧行数据，其对应的侧行反馈信息在时隙5进行传输。如果网络设备为终端设备在时隙0、时隙2分配了传输资源，则隐式指示终端设备可以在接收到侧行反馈之前发送重传数据。例如终端设备在时隙0发送了侧行数据，其对应的侧行反馈在时隙5，由于网络设备为终端设备在时隙2也分配了传输资源，因此终端设备可以在时隙2发送重传数据，而不需要等到时隙5的反馈信息之后再发送重传。Optionally, in Example 2, for example, if the time domain period of the side-line feedback resource is 4, that is, every 4 time slots includes a side-line feedback time slot. As shown in FIG. 10, time slots 0-3 The side row data, and its corresponding side row feedback information is transmitted in time slot 5. If the network device allocates transmission resources for the terminal device in time slot 0 and time slot 2, it implicitly indicates that the terminal device can send retransmission data before receiving the sideline feedback. For example, a terminal device sends sideline data in time slot 0, and its corresponding side row feedback is in time slot 5. Since the network device also allocates transmission resources for the terminal device in time slot 2, the terminal device can send retransmission in time slot 2. Data is transmitted without waiting for the feedback information in slot 5 before sending a retransmission.

因此，在本申请实施例中，终端设备可以确定在接收到针对第一侧行数据的侧行反馈之前是否进行针对第一侧行数据的重传，从而可以保证侧行数据的时延需求、可靠性需求等。Therefore, in this embodiment of the present application, the terminal device can determine whether to retransmit the first side row data before receiving the side row feedback for the first side row data, so that the delay requirements of the side row data can be guaranteed, Reliability requirements, etc.
