具体实施方式
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清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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。
参见图1，图1是本申请实施例提供的网络架构示意图。在图1中，在传统的蜂窝网络中，用户设备120和基站(Base Station，BS)110进行通信，此时用户设备120和基站110之间的链路被称为上行链路(Uplink，UL)或下行链路(Downlink，DL)。而在物物直连通信技术或边链路通信技术(Sidelink，SL)中，用户设备120直接和用户设备130进行通信，用户设备120和用户 设备130之间的链路称为直连链路(sidelink，SL)。其中，在边链路通信技术中，用户设备120称为发送设备(Transmitter User Equipment，Tx UE)，用户设备120称为接收设备(Receiver User Equipment，Rx UE)。
其中，用户设备120基于基站110分配的边链路资源可向用户设备130发送通信数据。并且边链路上传输资源或者叫授权(SL grant)可以是基站110通过下行控制信息(Downlink Control Information，DCI)分配，即基站110动态调度边链路上的传输资源；也可以是基站110通过无线资源控制(Radio Resource Control，RRC)信令分配的周期性的资源。
上行链路中，用户设备120直接将通信数据发送至基站110，基站110能通过自己是否解码成功判断是否需要重传。由于边链路传输资源是由基站110分配的，用户设备120在基于边链路传输资源将通信数据发送至用户设备130后，需要等待用户设备130在物理边链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)发送否定应答(non-acknowledge，NACK)之后，再通过物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)转发否定应答给基站110，基站110才能调度用户设备120重传。
其中，本申请实施例中的网络结构可适用于5G(5Generation)通信系统，还可适用于4G、3G通信系统，还可适用于未来新的各种通信系统，例如6G、7G等。
本申请实施例提供中的网络架构包括但不限于中继网络架构、双链接架构、车辆到任何物体的通信(Vehicle-to-Everything)架构等架构，具体可根据实际应用场景确定，在此不做限制。
本申请实施例中的基站是一种部署在无线接入网(Radio Access Network，RAN)用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备，如基地无线收发站(Base Transceiver Station，BTS)；3G网络中提供基站功能的设备，如节点B(NodeB)；在4G网络中提供基站功能的设备，如演进的节点B(evolved NodeB，eNB)；在无线局域网络(Wireless Local Area Networks，WLAN)中，提供基站功能的设备为接入点(access point，AP)，5G新无线(New Radio，NR)中的提供基站功能的设备gNB,以及继续演进的节点B(ng-eNB)。其中gNB和终端之间采用NR技术进行通信，ng-eNB 和终端之间采用进化的UMTS陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)技术进行通信，gNB和ng-eNB均可连接到5G核心网。本申请实施例中的基站还包含在未来新的通信系统中提供基站功能的设备等，具体可根据实际应用场景确定，在此不做限制。
其中，上述核心网可以是演进型分组核心网(evolved packet core，EPC)、5G Core Network(5G核心网)，还可以是未来通信系统中的新型核心网。5G Core Network由一组设备组成，并实现移动性管理等功能的接入和移动性管理功能(Access and Mobility Management Function，AMF)、提供数据包路由转发和QoS(Quality of Service)管理等功能的用户面功能(User Plane Function,UPF)、提供会话管理、IP地址分配和管理等功能的会话管理功能(Session Management Function，SMF)等。EPC可由提供移动性管理、网关选择等功能的MME、提供数据包转发等功能的Serving Gateway(S-GW)、提供终端地址分配、速率控制等功能的PDN Gateway(P-GW)组成。
本申请实施例中的用户设备(发送设备或者接收设备)可以是接入终端、用户单元、用户站、移动站、移动台(Mobile Station，MS)、远方站、远程终端、移动设备、用户终端、终端设备(Terminal Equipment)、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、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处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，具体也可根据实际应用场景确定，在此不做限制。
本申请实施例提供的边链路数据传输方法(为方便描述，以下简称本申请实施例提供的方法)可适用于边连接通信技术中的发送设备。参见图2，图2是本申请实施例提供的边链路数据传输方法的第一流程示意图。图2所示的边链路数据传输方法可包括如下步骤S201。
S201、接收否定应答，启动第一配置授权定时器，以在第一配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，发送设备可基于边链路传输资源向接收设备发送通信数据，接收设备可对通信数据进行解码并在解码失败后，通过物理边链路反馈信道向发送设备发送否定应答。其中，否定应答用于表示接收设备对通信数据解码失败。发送设备通过物理上行控制信道向基站转发否定应答，以请求基站调度重传。由于发送设备从边链路反馈信道接收否定应答至基于否定应答请求基站调度重传的过程中需要一定的时间，为确保发送设备能将否定应答成功发送至基站，发送设备在接收到否定应答后可启动第一配置授权定时器以在第一配置授权定时器的运行时间内，不使用与传输通信数据的边链路传输资源属于同一混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程的边链路预配置授权。
在本申请实施例中，发送设备启动配置授权定时器包括发送设备对配置授权定时器在未运行状态下的启动，也包括发送设备对配置授权定时器进行的重启。为方便描述，针对发送设备启动或者重启配置授权定时器的动作简称为启动配置授权定时器，以下不再赘述。
参见图3，图3是本申请实施例提供的边链路数据传输的第一场景示意图。在图3中，发送设备在接收到接收设备通过物理边链路反馈信道发送的否定应答后，启动第一配置授权定时器。其中，第一配置授权定时器由基站发送的下行控制信息配置，即基站通过下行控制信息配置发送设备在接收到否定应答后启动第一配置授权定时器。其中，发送设备从接收到否定应答开始，到向基站发送否定应答为止的时间段为第一配置授权定时器的运行时间。并且第一配置授权定时器的运行时间由基站发送的无线资源控制信令配置。
可选地，第一配置授权定时器的运行时间还可以为从接收到否定应答开始至向基站发送否定应答后的第一预设时间点为止的时间段内，以确保在确定基站不会调度发送设备进行重传或者接收到基站分配的新的边链路传输资源期间内，不使用与传输通信数据的边链路传输资源属于同一混合自动重传请求进程的边链路预配置授权。其中，上述预设时间点可根据实际应用场景确定，在此不做限制。
参见图4，图4是本申请实施例提供的边链路数据传输方法的第二流程示意图。图4所示的边链路数据传输方法可包括如下步骤S401至S402。
S401、接收否定应答，启动第一配置授权定时器，以在第一配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，步骤S401的具体实施方式可参见图2中步骤S201所示的实施方式，在此不再赘述。
S402、向基站发送否定应答，启动第二配置授权定时器，以在第二配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，发送设备在接收到接收设备通过物理边链路反馈信道发送的否定应答之后，需要将否定应答通过物理上行控制信道转发至基站，以使基站重新分配新的边链路传输资源。由于发送设备在将否定应答发送至基站，以使基站重新向发送设备分配新的边链路传输资源，或者确定基站不再进行重传调度需要一定的时间。因此为了确保发送设备可成功将否定应答发送至基站，并确保基站不会调度发送设备进行重传或者接收到基站分配的新的边链路传输资源，发送设备在通过物理上行控制信道向基站发送否定应答之后可启动第二配置授权定时器，以在第二配置授权定时器的运行时间内不使用与传输通信数据的边链路传输资源属于同一混合自动重传请求进程的边链路预配置授权。
参见图5，图5是本申请实施例提供的边链路数据传输的第二场景示意图。在图5中，发送设备在向基站发送否定应答之后，可启动第二配置授权定时器。并且第二配置授权定时器由基站发送的下行控制信息配置，即基站通过下行控制信息配置发送设备在通过物理上行控制信道向基站发送否定应答后启动第二配置授权定时器。其中，第二配置授权定时器的运行时间为从向基站发送否定应答开始后的第二预设时间点为止的时间段，在第二配置授权定时器的运行时间内可确保发送设备可成功将否定应答发送至基站，并确保基站不会调度发送设备进行重传或者接收到基站分配的新的边链路传输资源。其中，第二配置授权定时器的运行时间由基站发送的无线资源控制信令配置。
参见图6，图6是本申请实施例提供的边链路数据传输方法的第三流程示意图。图6所示的边链路数据传输方法可包括如下步骤S601至S603。
S601、接收边链路传输资源，启动第三配置授权定时器，以在第三配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，发送设备在接收到基站分配的边链路传输资源后，可基于边链路传输资源向接收设备发送通信数据。其中，边链路传输资源可以是基站通过下行控制信息动态分配，也可以是基站通过无线资源控制信令配置的周期性资源，具体可基于实际应用场景确定，在此不做限制。
由于发送设备在接收到基站分配的边链路传输资源至基于边链路传输资源向接收设备发送通信数据需要一定的时间，并且如果发送设备在未成功将通信数据发送至接收设备时，使用与发送该通信数据的边链路传输资源属于同一混合自动重传请求进程，会导致该通信数据被清空。因此，发送设备在接收到基站分配的边链路传输资源之后可启动第三配置授权定时器，以在第三配置授权定时器的运行时间内不使用与发送该通信数据的边链路传输资源属于同一混合自动重传请求进程。
S602、接收否定应答，启动第一配置授权定时器，以在第一配置授权定时器的运行时间内不使用边链路预配置授权。
S603、向基站发送否定应答，启动第二配置授权定时器，以在第二配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，步骤S602至S603的具体实施方式可参见图4中步骤S401至S402所示的实现方式，在此不再赘述。
参见图7，图7是本申请实施例提供的边链路数据传输的第三场景示意图。在图7中，发送设备接收到基站分配的边链路传输资源之后，可启动第三配置授权定时器，并且基站通过下行控制信息配置发送设备在接收到基站分配的边链路传输资源后启动第三配置授权定时器。其中，第三配置授权定时器的运行时间为从接收到基站分配的边链路传输资源开始至向接收设备发送通信数据为止。并且第三配置授权定时器的运行时间由基站发送的无线资源控制信令配置。
参见图8，图8是本申请实施例提供的边链路数据传输方法的第四流程示意图。图8所示的边链路数据传输方法可包括如下步骤S801至S804。
S801、接收边链路传输资源，启动第三配置授权定时器，以在第三配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，步骤S801的具体实施方式可参见图6中步骤 S601所示的实现方式，在此不再赘述。
S802、基于边链路传输资源向接收设备发送通信数据，启动第四配置授权定时器，以在第四配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，由于发送设备将通信数据发送至接收设备后，如果在通信数据发送成功之前或者在接收设备对通信数据解码成功之前，发送设备使用了与传输通信数据的边链路传输资源属于同一混合自动重传请求进程的预配置授权，会导致之前发送的通信数据被清空，或者导致发送设备长时间等待重传调度。因此，发送设备在基于边链路传输资源向接收设备发送通信数据后，可启动第四配置授权定时器，以在第四配置授权定时器的运行时间内不使用与传输通信数据的边链路传输资源属于同一混合自动重传请求进程的其他传输资源。
S803、接收否定应答，启动第一配置授权定时器，以在第一配置授权定时器的运行时间内不使用边链路预配置授权。
S804、向基站发送否定应答，启动第二配置授权定时器，以在第二配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，步骤S803至S804的具体实施方式可参见图6中步骤S602至S603所示的实现方式，在此不再赘述。
参见图9，图9是本申请实施例提供的边链路数据传输的第四场景示意图。在图9中，发送设备在基于边链路传输资源向接收设备发送通信数据之后可启动第四配置授权定时器，并且第四配置授权定时器由基站发送的下行控制信息配置，即基站通过下行控制信息配置发送设备在向接收设备发送通信数据后启动第四配置授权定时器。其中，第四配置授权定时器的运行时间为从向接收设备发送通信数据开始至接收设备发送用于表示解码失败的否定应答为止，或者到一定时间段(具体可根据实际应用场景确定，在此不做限制)为止以确保接收设备解码成功。并且第四配置授权定时器的运行时间由基站发送的无线资源控制信令配置。
在本申请实施例中，通过设置配置授权定时器可使边链路通信中的发送设备有足够时间等待基站调度重传，减少发送设备的传输时延和调度重传时延，适用性高。
参见图10，图10是本申请实施例提供的边链路数据传输方法的第五流程示意图。图10所示的边链路数据传输方法可包括如下步骤S101。
S101、向基站发送否定应答，启动第五配置授权定时器，以在第五配置授权定时器的运行时间内不使用边链路预配置授权。
在一些可行的实施方式中，基站向发送设备分配边链路传输资源，发送设备基于边链路传输资源向接收设备发送通信数据。当接收设备对通信数据解码失败后会通过物理边链路反馈信道向发送设备发送否定应答，以表示接收设备对通信数据解码失败。进而发送设备可将否定应答通过物理上行控制信道发送至基站以使基站分配新的边链路传输资源。由于发送设备在将否定应答发送至基站，以使基站重新向发送设备分配新的边链路传输资源或者确定基站不再进行重传调度需要一定的时间。因此为了确保发送设备可成功将否定应答发送至基站，并确保基站不会调度发送设备进行重传或者接收设备可接收到基站分配的新的边链路传输资源，发送设备在通过物理上行控制信道向基站发送否定应答之后可启动第五配置授权定时器，以在第五配置授权定时器的运行时间内不使用与传输通信数据的边链路传输资源属于同一混合自动重传请求进程的边链路预配置授权。
参见图11，图11是本申请实施例提供的边链路数据传输的第五场景示意图。在图11中，发送设备在向基站发送否定应答之后，可启动第五配置授权定时器。并且第五配置授权定时器由基站发送的下行控制信息配置，即基站通过下行控制信息配置发送设备在通过物理上行控制信道向基站发送否定应答后启动第五配置授权定时器。其中，第五配置授权定时器的运行时间为从向基站发送否定应答开始后的第五预设时间点为止的时间段，在第五配置授权定时器的运行时间内可确保发送设备可成功将否定应答发送至基站，并确保基站不会调度发送设备进行重传或者接收到基站分配的新的边链路传输资源。其中，第五配置授权定时器的运行时间由基站发送的无线资源控制信令配置。
可选地，在第五配置授权定时器参与的情况下，当发送设备接收到接收设备发送的否定应答后，可启动第六配置授权定时器，以在第六配置授权定时器的运行时间内不使用边链路预配置授权。其中，第六配置授权定时器的具体实施方式可参见图2中步骤S201所示的实现方式，在此不再赘述。
可选地，发送设备还可在接收到基站分配的边链路传输资源后启动第七配置授权定时器，以在第七配置授权定时器的运行时间内不使用边链路预配置授权。或者，发送设备在基于边链路传输资源向接收设备发送通信数据后可启动第八配置授权定时器，以在第八配置授权定时器的运行时间内不使用边链路预配置授权。其中，第七配置授权定时器的具体实施方式可参见图6中步骤S601所示的实现方式，在此不再赘述。其中，第八配置授权定时器的具体实施方式可参见图8中步骤S802所示的实现方式，在此也不再赘述。
在本申请实施例中，通过设置配置授权定时器可使边链路通信中的发送设备有足够时间等待基站调度重传，减少发送设备的传输时延和调度重传时延，适用性高。
