技术领域
本申请涉及无线通信技术领域，特别涉及一种直接通信接口重复传输的方法、终端及网络侧设备。
背景技术
5G新空口(New Radio，NR)系统主要支持三类业务：增强型宽带通信(enhanced Mobile Broadband，eMBB)、大量机器类型通信(massive Machine Type Communications，mMTC)，高可靠低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)；
为了支持行业垂直应用，引入了NR车到万物(Vehicle to Everything，V2X)，为了提升V2X消息传输的可靠性并降低时延，可以支持重复传输。例如目前URLLC业务引入重复传输机制，通过多个路径传输相同的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层协议数据单元(Protocol Data Unit，PDU)，通过多路传输增益提升传输可靠性，并降低传输时延。
对于长期演进(Long Term Evolution，LTE)车到万物(V2X)，直接通信接口重复传输机制中重复传输使用的两个无线承载(Radio Bearer，RB)对应的逻辑信道参数是预先约定好对应关系的，例如假设一个重复传输使用的RB对应的逻辑信道参数为逻辑信道号m(Logical Channel ID m，LCID m)，那么另一个重复传输使用的RB对应的逻辑信道参数必然使用LCID n，其中m、n为正整数；
但是对于5G NR V2X，逻辑信道是由网络配置的，如果重复传输使用的两个无线承载RB对应的逻辑信道参数之间关联关系仍然采用固定的，那么逻辑信道分配将不太灵活，在直接通信接口必须要预留一部分专用于重复传输的逻辑信道，导致逻辑信道利用率较低。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，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它实施例，都属于本申请保护的范围。
对于5G新空口NR，为了支持行业垂直应用，引入了NR车到万物V2X，为了提升V2X消息传输的可靠性并降低时延，可采用重复传输方法，如图1所示，传统的无线通信采用蜂窝网络通信方式，即终端101和网络侧设备100通过Uu接口进行上下行数据和/或控制信息的传输，终端102和网络侧设备100通过Uu接口进行上下行数据和/或控制信息的传输，下面首先对5G Uu接口重复传输进行简单介绍：
5G NR系统主要支持如下三类业务：
增强型宽带通信(enhanced Mobile Broadband，eMBB)；
大量机器类型通信(massive Machine Type Communications，mMTC)；
高可靠低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)；
对于URLLC，由于URLLC对时延和可靠性都有比较高的要求，目前第三代合作伙伴计划(Third Generation Partnership Project，3GPP)给出的一种解决方案是引入重复传输机制，即通过多个路径传输相同的PDCP层PDU，通过多路传输增益提升传输可靠性，并降低传输时延。
如图2A所示，对于载波聚合(Carrier aggregation，CA)下的重复传输的模型：
PDCP层的一个无线承载RB，在无线链路控制(Radio Link Control，RLC)层通过多个逻辑信道Logical Channel分别进行传输，每个RB对应一个PDCP实体，每个逻辑信道对应一个RLC实体。重复传输的RB对应的多个逻辑信道在媒体接入控制(Medium Access Control，MAC)层由一个MAC实体进行处理，将来自不同RLC逻辑信道的数据映射到一个或多个载波进行传输。
如图2B所示，对于双连接(Dual connectivity，DC)下的重复传输的模型：
PDCP层的一个无线承载RB，在RLC层通过多个逻辑信道Logical Channel分别进行传输，每个RB对应一个PDCP实体，每个逻辑信道对应一个RLC实体。重复传输的RB对应的多个逻辑信道分别映射到不同的MAC 实体，不同RLC实体对应的逻辑信道的数据映射到不同载波上进行传输。
由于在LTE V2X中，直接通信接口重复传输机制中重复传输使用的两个无线承载RB对应的逻辑信道参数是预先约定好对应关系的，但是对于5G NR V2X，逻辑信道是由网络配置的，如果重复传输使用的两个无线承载RB对应的逻辑信道参数之间关联关系仍然采用固定的，那么逻辑信道分配将不太灵活，在直接通信接口必须要预留一部分专用于重复传输的逻辑信道，导致逻辑信道利用率较低，因此本申请实施例提供的一种直接通信方式，用于提供一种更灵活的直接通信接口重复传输机制。
如图3所示，直接通信是指终端之间可以通过直接通信链路(也称为Sidelink)进行数据传输的方式，如终端300与终端301可通过Sidelink链路进行直接通信，Sidelink链路对应的无线接口称为直接通信接口，也称为Sidelink接口或者PC5接口。其中，V2X的数据可以通过Uu口传输，也可以通过直接通信接口传输，具体使用哪个接口传输由高层决定。
本申请实施例提供的一种接通信接口重复传输的方法，可以应用于终端，也可以应用于网络侧设备。
需要说明的是，所述终端是一种具有无线通信功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)所述终端、增强现实(augmented reality，AR)所述终端、工业控制(industrial control)中的无线所述终端、无人驾驶(self driving)中的无线所述终端、远程医疗(remote medical)中的无线所述终端、智能电网(smart grid)中的无线所述终端、运输安全(transportation safety)中的无线所述终端、智慧城市(smart city)中的无线所述终端、智慧家庭(smart home)中的无线所述终端等；还可以是各种形式的UE，移动台(mobile station，MS)，所述终端设备(terminal device)。
所述网络侧设备可以是5G中的gNB、宏基站、微基站，集中单元(Central  Unit，CU)或者分布式单元(Distributed Unit，DU)等。
本申请实施例中术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
