  • HARQ feedback information is carried in a side-line feedback channel, such as a physical side-link feedback channel (PSFCH).
  • PSFCH physical side-link feedback channel
  • side feedback can be activated or deactivated through pre-configuration information or network configuration information. If the side-line feedback is activated, the terminal device at the receiving end receives the side-line data sent by the terminal device at the transmitting end, and feeds back HARQ acknowledgement (ACK) or negative (NACK) to the terminal device at the transmitting end according to the detection result. The terminal device at the sending end sends retransmission data or sends new data according to the feedback information of the terminal device at the receiving end. If the sideline feedback is deactivated, the terminal device at the receiving end does not need to send feedback information, and the terminal device at the sending end usually sends data in a blind transmission manner.

Therefore, the terminal device needs to send two feedback messages in time slot 7. That is, the terminal device needs to send two side feedback channels in time slot 7. These two feedback channels are respectively Used to carry feedback information sent to UE1 and UE3.

  • Method 2 The terminal device only sends one side-line feedback channel: the terminal device can select the side-line feedback channel corresponding to the side-line data with the highest priority according to the priority of the side-line data corresponding to the side-line feedback information to ensure high priority Transmission performance of side row data.

具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
D2D通信是基于SL传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，因此具有更高的频谱效率以及更低的传输时延，车联网系统采用D2D通信的方式(即设备到设备直接通信的方式)。对于D2D通信，第三代合作伙伴计划(Third Generation Partnership Project，3GPP)定义了两种传输模式：第一模式(也称为模式A)和第二模式(也称为模式B)。第一模式是网络设备为终端设备分配传输资源，第二模式是终端设备自主选择传输资源。
针对第一模式：如图1所示，终端设备的传输资源是由基站分配的，终端设备根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。
针对第二模式：如图2所示，终端设备在资源池中选择一个传输资源进行数据的发送。
在新无线-车辆到其他设备(New Radio-Vehicle to Everything，NR-V2X)中，需要支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如 更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X中，支持广播传输方式、单播传输方式和组播传输方式。对于单播传输方式，如图3所示，只有一个接收端的终端设备，UE1与UE2之间进行单播传输。对于组播传输方式，接收端是一个通信组内的所有终设备，或者是在一定传输距离内的所有终端设备。对于组播传输方式，如图4所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1是发送端的终端设备，用于发送数据，该组内的UE2、UE3和UE4都是接收端的终端设备，用于接收数据。对于广播传输方式，接收端可以是任意一个终端设备，如图5所示，UE1是发送端的终端设备，用于发送数据，UE1周围的其他终端设备，如UE2、UE3、UE4、UE5、UE6和UE7都是接收端的终端设备，用于接收数据。
在NR-V2X中，为了提高系统的可靠性，引入了侧行反馈信道。侧行反馈的流程示意图，如图6所示，对于单播传输方式，发送端的终端设备向接收端的终端设备发送侧行数据(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))，接收端的终端设备向发送端的终端设备发送反馈信息，如混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息；发送端的终端设备根据接收端的终端设备的反馈信息判断是否需要进行数据重传。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)。
在一些实施例中，可通过预配置信息或网络配置信息激活或者去激活侧行反馈。如果侧行反馈被激活，则接收端的终端设备接收发送端的终端设备发送的侧行数据，并根据检测结果向发送端的终端设备反馈HARQ确认(ACK)或否认(NACK)。发送端的终端设备根据接收端的终端设备的反馈信息发送重传数据或者发送新数据。如果侧行反馈被去激活，则接收端的终端设备不需要发送反馈信息，发送端的终端设备通常采用盲传的方式发送数据。例如，发送端的终端设备对每个侧行数据重复发送K次，而不是根据接收端的终端设备的反馈信息决定是否需要发送重传数据。
为了降低PSFCH的开销，可以利用一个时隙上包括的PSFCH传输资源传输针对N个时隙上的侧行数据的反馈信息；可选地，N＝1、2、4，N为预配置或者由网络设备配置；以N＝4为例，终端设备传输反馈信息的示意图，如图7所示，在时隙2、时隙3、时隙4和时隙5中传输的PSSCH， 其对应的反馈信息都是在时隙7中传输；因此，可以把时隙2、时隙3、时隙4和时隙5看作一个时隙集合，该时隙集合中传输的PSSCH对应的PSFCH是在相同的时隙中传输。
对于单播传输并且已经激活侧行反馈的情况下，如果UE1在时隙2向UE2发送PSSCH，则UE2需要在时隙7向UE1发送侧行反馈；如果UE3在时隙3向UE2发送PSSCH，UE2需要在时隙7向UE3发送侧行反馈，因此，终端设备需要在时隙7发送两个反馈信息，即终端设备需要在时隙7发送2个侧行反馈信道，这2个反馈信道分别用于承载向UE1和UE3发送的反馈信息。
终端设备在同一时刻同时需要发送的侧行反馈信道大于一个的情况，可以包括下述两种方式：
方式1：终端设备同时发送两个侧行反馈信道：两个侧行反馈信道会共享终端设备的发送功率；如果终端设备的发送功率受限，将会导致每个侧行反馈信道的发送功率都较低，进而降低PSFCH的性能。
方式2：终端设备只发送一个侧行反馈信道：终端设备可以根据侧行反馈信息对应的侧行数据的优先级，选取优先级最高的侧行数据对应的侧行反馈信道，保证高优先级的侧行数据的传输性能。
本申请实施例提供一种侧行反馈方法，本申请实施例的侧行反馈方法可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
本申请实施例提供的侧行反馈方法的一种可选处理流程，如图8所示，包括以下步骤：
步骤S101，终端设备获取第一配置信息；所述第一配置信息用于确定侧行反馈方式，或者，所述第一配置信息用于确定所述终端设备在同一时刻能够同时传输的侧行反馈信道的最大数目。
在一些实施例中，终端设备可以根据预配置信息，获取所述第一配置 信息。在具体实施时，所述预配置信息可以是资源池配置信息；在资源池配置信息中携带第一配置信息。
在另一些实施例中，在终端设备在小区覆盖范围内的情况下，终端设备可以接收小区所对应的网络设备发送的第一配置信息。在具体实施时，在网络设备向终端设备发送第一配置信息的情况下，第一配置信息可以携带于广播消息、或无线资源控制(Radio Resource Control，RRC)信令、或下行控制信息(Downlink Control Information，DCI)。举例来说，网络设备通过系统信息(System Information Block，SIB)向终端设备发送用于侧行传输的资源，在SIB信息内可携带第一配置信息。再举例来说，针对处于连接态(RRC-Connected)的终端设备，网络设备可通过RRC信令为终端设备配置资源池信息；在所述资源池配置信息中可以包括第一配置信息。或者，网络设备通过DCI为终端设备配置侧行传输资源；在所述DCI中可以携带第一配置信息。
在又一些实施例中，终端设备可以接收另一终端设备发送的第一配置信息。在具体实施时，另一终端设备向终端设备发送第一配置信息的情况下，第一配置信息可以携带于物理侧行广播信道(Physical Sidelink Broadcast Channel，PSBCH、或PSCCH、或PSSCH、或侧行RRC信令中。其中，所述另一终端设备可以是获取第一配置信息的终端设备所在的通信组的组头终端设备；其中，所述组头终端设备可以是在通信组内具有资源管理、资源分配、资源调度或资源控制等功能的终端设备。
在一些实施方式中，所述第一配置信息包括第一信息域，所述第一信息域是1比特的情况下，所述第一配置信息用于确定侧行反馈方式；在所述第一信息域是N比特的情况下，所述第一配置信息用于确定所述终端设备在同一时刻能够同时传输的侧行反馈信道的最大数目，N为大于1的正整数。
其中，所述第一配置信息用于确定侧行反馈方式的情况下，所述侧行反馈方式至少可以包括：所述终端设备在同一时刻只能传输一个侧行反馈信道；或者，所述终端设备在同一时刻能够传输两个或两个以上的侧行反馈信道。
这里，所述终端设备在同一时刻能够传输两个或两个以上的侧行反馈信道，也可以理解为，终端设备在同一时刻能够传输大于一个的侧行反馈信道，且对终端设备在同一时刻能够传输的侧行反馈信道的最大数目不进行限定；由终端设备根据检测到的侧行数据判断终端设备传输侧行反馈信 道的数目。例如，在图7中，如果终端设备在时隙2检测到5个侧行数据，包括3个广播方式发送的侧行数据(不需要发送反馈信息)和2个单播方式发送的侧行数据(需要发送反馈信息)；在时隙3检测到3个侧行数据，包括2个广播方式发送的侧行数据(不需要发送反馈信息)和1个单播方式发送的侧行数据(需要发送反馈信息)；在时隙4没检测到侧行数据，在时隙5检测到1个单播方式发送的侧行数据(需要发送反馈信息)，则该终端设备在时隙7需要发送的侧行反馈信道的数目是4个。
在所述第一配置信息用于确定所述终端设备在同一时刻能够同时传输的侧行反馈信道的最大数目的情况下，若终端设备待传输的侧行反馈信道的数目小于或等于所述终端设备在同一时刻能够传输的侧行反馈信道的最大数目，所述终端设备传输全部待传输的侧行反馈信道。若终端设备需要传输的侧行反馈信道的数目大于所述终端设备在同一时刻能够传输的侧行反馈信道的最大数目，所述终端设备根据所述需要传输的侧行反馈信道对应的数据的优先级，在所述需要传输的侧行反馈信道中确定优先级最高的M个侧行反馈信道为待传输的侧行反馈信道，所确定的M个侧行反馈信道用于终端设备传输；M等于所述终端设备在同一时刻能够传输的侧行反馈信道的最大数目。
因此，若终端设备需要传输的侧行反馈信道为第一侧行反馈信道集合，终端设备根据所述需要传输的侧行反馈信道对应的数据的优先级，在第一侧行反馈信道集合中选择优先级最高的M个侧行反馈信道形成第二侧行反馈信道集合；所述第二侧行反馈信道集合为第一侧行反馈信道集合的子集，第二侧行反馈信道集合内侧行反馈信道的数目可以等于或小于终端设备在同一时刻能够传输的侧行反馈信道的最大数目。举例来说，终端设备需要传输的侧行反馈信道的数量为10个，终端设备在同一时刻能够传输的侧行反馈信道的最大数目为6个，则终端设备根据需要传输的侧行反馈信道对应的数据的优先级，在需要传输的10个侧行反馈信道中，选择优先级最高的6个侧行反馈信道作为待传输的侧行反馈信道。
在一些实施方式中，在待传输的侧行反馈信道的数目为两个或两个以上的情况下，所述方法还包括：
步骤S102，终端设备确定传输所述待传输的侧行反馈信道的功率。
在一些实施例中，终端设备根据所述终端设备的最大发送功率，平均分配所述待传输的侧行反馈信道的功率。可选地，在多个侧行反馈信道上平均分配功率包括以下情况之一：每个侧行反馈信道的总功率相等，或者 侧行反馈信道的功率谱密度(Power Spectrum Density，PSD)相同。举例来说，终端设备的最大发送功率为P，待传输的侧行反馈信道的数目为M，则每个待传输的侧行反馈信道的发送功率为P/M，即每个侧行反馈信道的总功率相等。又例如，终端设备的最大发送功率为P，待传输的侧行反馈信道的数目为2个，每个侧行反馈信道占据一个PRB，则每个PRB上的功率谱密度是P/2，即各个反馈信道的功率谱密度相同，并且各个反馈信道的总功率相等。又例如，终端设备的最大发送功率为P，待传输的侧行反馈信道的数目为2个，第一个侧行反馈信道占据一个PRB，第二个侧行反馈信道占据两个PRB，则每个PRB上的功率谱密度是P/3，即各个反馈信道的功率谱密度相同，但是各个反馈信道的总功率不同。
在另一些实施例中，终端设备根据所述待传输的侧行反馈信道对应的数据的优先级，确定所述待传输的侧行反馈信道的功率。可选地，在所述待传输的侧行反馈信道的发送功率之和大于所述终端设备的最大发送功率的情况下，所述终端设备降低优先级低的数据对应的侧行反馈信道的发送功率；或者，所述终端设备不为优先级低的数据对应的侧行反馈信道分配发送功率。其中，不为优先级低的数据对应的侧行反馈信道分配发送功率，可以是为优先级低的数据对应的侧行反馈信道分配的发送功率为零。如果具有对应着最低优先级的侧行反馈信道的功率降低到0，各个侧行反馈信道的发送功率之和仍然大于最大发送功率，会将此对应次低优先级的侧行反馈信道的功率，以此类推，直至发送功率之和小于等于终端设备的最大发送功率。
举例来说，如果终端设备待传输的侧行反馈信道数目是3，待传输的第一侧行反馈信道对应的侧行数据的优先级是2，待传输的第二侧行反馈信道对应的侧行数据的优先级是3，待传输的第三侧行反馈信道对应的侧行数据的优先级是4。根据侧行功率控制机制，待传输的第一侧行反馈信道的发送功率为P1，待传输的第二侧行反馈信道的发送功率为P2，待传输的第三侧行反馈信道的发送功率为P3。如果待传输的三个侧行反馈信道的发送功率之和大于终端设备的最大发送功率，则终端设备首先降低优先等级4对应的第三侧行反馈信道的发送功率，直至待传输的三个侧行反馈信道的发送功率之和低于终端设备的最大发送功率。如果待传输的第三侧行反馈信道的发送功率为P3＝0时，待传输的第一侧行反馈信道的发送功率P1与待传输的第二侧行反馈信道的发送功率P2之和仍大于终端设备的最大发送功率，此时再降低优先等级3对应的第二侧行反馈信道的发送功率，以此类 推，直至终端设备发送的侧行反馈信道的发送功率之和小于或等于终端设备的最大发送功率。
