本申请要求享有于2022年9月7日提交的名称为“副链路SL复制传输方法、终端及网络侧设备”的中国专利申请202211091821.1的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本申请属于通信技术领域，具体涉及一种副链路SL复制传输方法、终端及网络侧设备。
背景技术
长期演进(Long Term Evolution，LTE)系统从第12个发布版本开始支持副链路(Sidelink，SL)，副链路也可以称为侧链路、边链路等，用于终端之间不通过网络设备进行直接数据传输。
在LTE SL中虽然支持复制(duplication)的方式传输，但由于复制功能的开启是使用业务的可靠性需求门限(例如邻近服务(Proximity based Services，ProSe)中每数据包可靠性(ProSe Per-Packet Reliability，PPPR))来进行控制，对于新空口(New Radio，NR)SL系统来说，不再使用可靠性需求参数，而是引入了QoS配置(profile)、5G服务质量指示(5G QoS indicator，5QI)和PC5服务质量指示(PC5 QoS Indicator，PQI)等新的QoS参数，因此LTE的复制功能的启动方式在NR SL中已不再适用。
因此，针对NR SL，亟需实现一种复制传输方法。

第九方面，提供了一种通信系统，包括：第一终端及网络侧设备，所述第一终端可用于执行如第一方面所述的SL复制传输方法的步骤，所述网络侧设备可用于执行如第二方面所述的SL复制传输方法的步骤。
第十方面，提供了一种可读存储介质，所述可读存储介质上存储程序或指令，所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤，或者实现如第二方面所述的方法的步骤。

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。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备12也可以称为无线接入网设备、无线接入网(Radio  Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。核心网设备可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function，PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、统一数据管理(Unified Data Management，UDM)，统一数据仓储(Unified Data Repository，UDR)、归属用户服务器(Home Subscriber Server，HSS)、集中式网络配置(Centralized network configuration，CNC)、网络存储功能(Network Repository Function，NRF)，网络开放功能(Network Exposure Function，NEF)、本地NEF(Local NEF，或L-NEF)、绑定支持功能(Binding Support Function，BSF)、应用功能(Application Function，AF)等。需要说明的是，在本申请实施例中仅以NR系统中的核心网设备为例进行介绍，并不限定核心网设备的具体类型。
首先，对本申请实施例涉及到的相关概念进行介绍：
LTE SL的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE SL只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格服务质量(Quality of Service，QoS)需求的高级V2X业务将通过新空口(New Radio，NR)SL支持。
5G NR系统也可以支持终端之间直接通信的Sidelink接口，且支持广播(broadcast)，组播(groupcast)和单播(unicast)三种传输方式。单播顾名思义就是一对一(one to one)的传输。组播为一对多(one to many)的传输，广播也是one to many的传输，但是广播并没有终端属于同一个组的概念。目前SL单播和组播通信支持物理层混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈机制。
NR SL定义了两种资源分配模式(mode)，一种是mode1，为基站调度资源；另一种是mode2，终端自己决定使用什么资源进行传输，此时资源信息可能来自基站的广播消息或者预配置的信息。终端如果工作在基站范围内并且与基站有无线资源控制(Radio Resource Control)RRC连接，可以是mode1和/或mode2，终端如果工作在基站范围内但与基站没有RRC连接，只能工作在mode2。如果终端在基站范围外，那么只能工作在mode2，根据预配置的信息来进行V2X传输。
在LTE SL中，支持SL载波聚合(Carrier Aggregation，CA)和复制(duplication)的传输方式，但复制传输方式的启用较为简单，即当业务的可靠性需求PPPR高于一定门限时，即开启复制传输方式，而NR系统中不再使用该参数，因此LTE的复制传输的启动方式在NR系统中不能使用。因此，需要研究适用于NR SL系统的SL复制传输方案。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的SL复制传输方法进行详细地说明。
在一实施例中，本申请实施例的方法可以应用于如图2所示的场景中。
图3是本申请实施例提供的SL复制传输方法的流程示意图之一。如图3所示，本实施例提供的方法，包括步骤101和步骤102。
步骤101、第一终端接收网络侧设备发送的配置信息；配置信息包括以下至少一项：基于SL无线承载RB和/或QoS流为粒度的与复制功能是否开启相关的第一指示信息、复制功能的逻辑通道相关的信息、复制功能相关状态的指示信息。
具体地，第一终端是否开启复制功能，是per SL RB/QoS流指示的，例如，哪个(或哪些)SL RB/SL QoS流是开启复制功能的，哪个(或哪些)SL RB/SL QoS流是没开启复制功能的；对于开启复制功能的RB的逻辑通道相关的信息，例如需要给出RLC承载的配置信息、主腿信息(主逻辑通道信息)、载波组信息。
复制功能相关状态的指示信息，例如配置信息配置后是否处于激活状态或去激活状态、默认状态，例如在满足某些条件的情况下，自动恢复默认状态。
可选地，对于分量载波(Component Carrier，CC)集合的话，可以以终端为粒度进行配置，例如每个终端配置相同或不同的CC集合，也可以多个终端统一配置，一般情况下，不论是per终端或是统一配置，配置之后也是应用于每个终端的所有开启复制功能的SL RB。
步骤102、第一终端基于配置信息进行SL复制传输。
具体地，第一终端基于步骤101中配置的配置信息进行SL复制传输，例如向第二终端发送数据。
本实施例的方法，第一终端接收网络侧设备发送的配置信息；该配置信息用于辅助第一终端进行SL复制传输，配置信息包括以下至少一项：基于SL无线承载RB和/ 或QoS流为粒度的与复制功能是否开启相关的第一指示信息、复制功能的逻辑通道相关的信息、复制功能相关状态的指示信息；由于与复制功能是否开启相关的第一指示信息是基于SLRB和/或QoS流为粒度进行配置的，便于对SL复制传输进行较为精细的控制，例如可以结合当前具体的系统负荷或链路情况等进行配置，从而使得SL链路能够更好的获得复制传输的增益，而且还可以基于复制功能的逻辑通道相关的信息、复制功能相关状态的指示信息进行复制传输，实现复杂度较低。
可选地，第一指示信息包括以下至少一项：
开启复制功能的SL无线承载RB的信息；
开启复制功能的QoS流的信息；
未开启复制功能的SL RB的信息；
未开启复制功能的QoS流的信息；
开启复制功能的第一条件。
可选地，第一条件包括以下至少一项：
误块率小于或等于第一门限、时延指标小于或等于第二门限、优先级小于或等于第三门限、信道繁忙率小于或等于第四门限。
具体地，第一指示信息是基于SL RB和/或SL QoS流为粒度的，即通过第一指示信息可以显示指示哪个(或哪些)SL RB/SL QoS流是开启复制功能的，哪个(或哪些)SL RB/SL QoS流是没开启复制功能的；
由于SL RB至少有一个逻辑通道是始终都要配置的，对于开启了复制功能的SL RB和/或SL QoS流，除它之外还可以配置第二个，第三个，第四个，…等，即对于复制传输来说，还需要额外配置逻辑通道例如RLC bearer的信息，例如，一个开启了复制功能的SL RB/QoS流，可以对应2个甚至更多RLC承载，其中，其中每个RLC承载将用于传输一份复制数据；
例如，还可以给出关于QoS流/SL RB和复制功能是否开启的关联信息，例如可以基于SL RB，在列出的SL RB列表中，哪些SL RB是开启复制功能的(那么映射到这些SL RB上的QoS流就都开启复制功能)，哪些SL RB是不开启复制功能的(那么映射到这些SL RB上的QoS流就都不开启复制功能)；或者也可以基于QoS流来指示复制功能是否开启，哪些QoS流的复制功能开启，哪些QoS流的复制功能不开启，对于开启复制功能的QoS流采取复制传输方式，或者对于开启复制功能的QoS流映射到的SL RB整个开启复制功能，反之不开启。
通常，一个PDCP实体是对应于一个SL RB的，对于PDCP实体来说是无法区分QoS流数据并感知QoS流是否开启复制功能，如果SL RB开启复制功能，则对应的QoS流都开启复制功能，如果SL RB对应的QoS流中一个QoS流开启复制功能，则该 SL RB开启复制功能，或，SL RB对应的QoS流中一个QoS流不开启复制功能，则SL RB不开启复制功能；
如果PDCP实体能够区分QoS流数据，并根据每个QoS流是否开启复制功能，针对对应的QoS流可以进行复制操作或不进行复制操作。
或，可以针对QoS流中的QoS特征，给出QoS特征和复制功能是否开启的关联配置，例如QoS特征满足第一条件则开启复制功能，例如，误块率(sl-PacketErrorRate)低于第一门限，时延指标(sl-PacketDelayBudget)低于第二门限，优先级(sl-PriorityLevel)低于第三门限(例如优先级数值越低，其重要性越高)等等，对于满足第一条件中至少一项的QoS流，开启复制功能，或者对于满足第一条件中至少一项的QoS流，它所在的SL RB整个都开启复制功能，否则不开启；
例如，SL链路满足一定条件，例如信道繁忙率(Channel Busy Ratio，CBR)小于或等于第四门限。
上述实施方式中，是否开启复制功能相关的配置信息的粒度较细，便于对SL复制传输进行更精细的控制，提升传输速率和接收效果，得到更好的用户体验和系统效率。
可选地，复制功能的逻辑通道相关的信息包括以下至少一项：
复制传输的逻辑通道的信息；
所述逻辑通道对应的载波组信息；
复制传输的主逻辑通道的信息。
可选地，逻辑通道的信息包括以下至少一项：
逻辑通道的数量、逻辑通道的无线链路管理RLC承载的信息。
可选地，载波组的数量大于或等于逻辑通道的数量。
具体地，配置信息可以配置复制传输的路径信息，即逻辑通道的信息，例如2条腿(leg)或者更多腿传输，逻辑通道的信息例如还可以包括关联的SL RB的标识ID。
对于开启了复制功能的SL RB/SL QoS流，需要配置载波组信息，例如两条腿的情况下，至少配置两个载波组，其中载波组1用于传输RLC承载1的数据，载波组2用于传输RLC承载2的数据；
对于开启了复制功能的SL RB/SL QoS流，配置主腿(即主逻辑通道)信息，即当复制功能去激活之后，数据需要通过哪个RLC承载进行传输。
可选地，复制功能相关状态的指示信息包括以下至少一项：
去激活状态的配置信息；
第二指示信息，所述第二指示信息用于指示所述配置信息配置后所述第一终端、SL RB或QoS流是否处于激活状态或去激活状态；
复制功能的默认状态，所述默认状态为满足第二条件后所述第一终端、SL RB或QoS流所处的状态。
可选地，去激活状态的配置信息包括以下至少一项：
去激活后的逻辑通道的信息；去激活后的逻辑通道对应的载波组信息；层2实体的操作配置信息。
具体地，去激活状态的配置信息，例如去激活之后，保留哪条腿传输，或者4条激活的腿去激活其中两条之后，保留哪两条腿，剩余的腿对应的载波组，L2实体是否需要有特殊操作处理等；
对于开启了复制功能的SL RB/SL QoS流，配置信息配置之后，是否处于激活/去激活状态，一般可以配置即激活，直接开始复制传输，即配置后就处于激活状态，也可以配置即去激活，即配置后就处于去激活状态，去激活后需要等待动态信令指示复制功能激活；或，也可以设定一些第二条件，满足第二条件之后，自动回到默认状态，例如当链路负荷较高时，自动回到复制功能的去激活状态；链路负荷较轻时，自动回到复制功能的激活状态。
可选地，在第二条件为目标参数的基于载波为粒度的测量结果小于或等于第四门限的情况下，默认状态为第一状态；
在第二条件为目标参数的基于载波为粒度的测量结果大于或等于第五门限的情况下，默认状态为第二状态；
第一状态为激活状态，第二状态为去激活状态；或，第一状态为去激活状态，第二状态为激活状态。
具体地，在第二条件为目标参数的基于载波为粒度的测量结果大于或等于第五门限的情况下，自动恢复到默认状态，例如测量结果表示链路负荷较高时，自动恢复到去激活状态；测量结果表示链路负荷较轻时，自动恢复到激活状态。
例如，信道繁忙率CBR小于或等于第四门限时，默认状态为激活状态；信道繁忙率CBR大于或等于第五门限时，默认状态为去激活状态；第四门限和第五门限可以相同或不同。
可选地，目标参数包括以下至少一项：信道繁忙率、参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)。
可选地，目标参数的基于载波为粒度的测量结果小于或等于第四门限包括以下至少一项：

上述实施方式中，在SL通信场景中对特定业务需要进行复制传输以达到可靠性和时延的超高要求，可以根据系统负荷、链路情况等给出配置，从而可以在SL链路上为符合需求的业务启动复制传输以及动态控制，以达到高QoS和系统效率等方面的通信性能和系统性能的保障与提升。
可选地，步骤101之前还可以包括：
第一终端向网络侧设备发送第一信息，第一信息包括以下至少一项：第一终端的业务服务质量QoS需求信息、第一终端的载波聚合CA能力信息、第一终端的复制能力信息、第二终端的载波聚合CA能力信息、第二终端的复制能力信息、至少一个载波的副链路测量结果。
具体地，对于处于Uu RRC连接态的SL TX终端说，如果发起SL单播业务，可以将自己SL的业务QoS需求信息上报给网络侧设备(例如服务基站)，从而获得网络侧设备的关于SL RB和/或资源的配置等。这样做的好处是，可以由网络侧设备很好的为该终端的该业务决定配置，充分考虑业务需求、终端能力和系统资源负荷等，以达到更精准和动态的配置效果。
那么，基于类似的原则，该TX终端还可以将自己和/或对端RX终端的CA和/或复制能力信息一起上报给网络侧设备，甚至可以上报在一些载波上的SL测量结果，网络侧设备根据这些信息，可以选择为该TX终端配置复制功能，可选地，可以以RRC专用信令的方式发给TX终端。
上述实施方式中，在接收配置信息之前终端可以将业务的QoS需求信息、终端的能力信息等反馈给网络侧设备，使得网络侧设备对复制传输的配置更有针对性，可以充分考虑业务需求、终端能力和系统资源负荷等，以达到更精准和动态的配置效果。
可选地，配置信息通过以下至少一项携带：
RRC专用信令、系统信息块SIB信令或预配置信令。
可选地，在第一终端处于连接态的情况下，配置信息通过RRC专用信令携带；
在第一终端处于非连接状态的情况下，配置信息通过SIB信令或预配置信令携带。
具体地，对于SL TX第一终端处于连接态(即第一终端为处于Uu RRC连接态的终端)，则网络侧设备可以通过RRC信令向该第一终端发送配置信息，例如RRC专用信令；
当SL TX第一终端处于非连接态，则不方便为其使用专用信令给出个性化的配置，因此，TX和RX终端之间以公共信令(例如系统信息块SIB信令)或预配置的方式获得统一的关于复制功能的配置信息，是比较可行的方式。
可选地，在第一终端处于连接态，且传输方式为单播方式的情况下，配置信息通过RRC专用信令携带；
在第一终端处于非连接状态，或传输方式为组播或广播方式的情况下，配置信息通过SIB信令或预配置信令携带。
具体地，在第一终端处于连接态，且传输方式为单播方式时，由于接收端只有一个二终端，因此可以使用专用信令给出个性化配置，而且信令开销和复杂度较低；
当SL TX第一终端处于非连接态，则不方便为其使用专用信令给出个性化的配置，或者TX第一终端发起的业务是组播或者广播，由于它的接收端是大量的RX第二终端，也无法为其使用专用信令给出个性化配置，否则由于RX第二终端数目众多且不断有第二终端动态的加入和离开，信令开销和复杂度过高。
因此，对于SL TX第一终端处于非连接态，或者TX第一终端发起的是组播或者广播业务，TX和RX终端之间以公共信令(例如系统信息块SIB信令)或预配置的方式获得统一的关于复制功能的配置信息，是比较可行的方式。
对于TX终端和RX终端来说，由于该些终端在业务开始之前，对于业务的QoS配置是理解一致的，而终端从公共信令或预配置信令里拿到的配置信息，也需要网络侧部署角度确保一定范围内的统一，因此TX终端和RX终端使用相同的QoS配置获得的关于复制功能的配置信息一般是一致的，因此TX终端和RX终端就可以基于一致的配置进行后续的复制传输。
可选地，通过SIB信令获得复制功能的配置信息的TX终端一般是处于Uu RRC IDLE或者非激活(INACTIVE)状态的终端；
通过预配置信令获得复制功能的配置信息的TX终端一般是处于脱网(Out Of Coverage，OOC)状态的终端。
进一步地，对于非单播业务，例如组播和广播，由于接收侧的终端数目众多，且接收侧终端也在不断的加入和退出，因此PC5接口交互效率不高。更适合采取预配置或者公共信令等方式，在TX和RX侧达到配置的统一，且对于RLC承载和SL RB/PDCP的关联关系，也需要采取一些静态或者预配置的方式，以达到两端的理解一致，例如为每个开启了复制功能的SL RB配置两个或者两个以上RLC承载，和/或两个RLC承载对应标识之间的关联，例如在传统逻辑信道标识(logical channel identify，LCID)区间中每个LCID都可以预留一个用于传输复制数据的LCID。当接收端终端接收到某些LCID对应的逻辑信道的数据，可以根据LCID之间的关联关系，将开启复制功能的两个RLC承载的数据送到一个PDCP实体进行统一的重复检测和重排序处理。
表1 SL-SCH LCID值

例如，在上述表1中，0-19是目前确定的用于SL的逻辑信道号，其中0-3为信令无线承载(Signaling Radio Bearers，SRB)，4-19为数据承载(Data Radio Bearers，DRB)，如果考虑DRB开启复制功能，则可以在预留的区间(逻辑信道号20-55范围)内，为每个DRB对应一个传输复制数据的逻辑信道的LCID，例如4-19一一按序对应于20-35。这样收发两端，就知道逻辑信道4和20传输的复制数据统一处理，其它类似。可选地，对于SRB可以采用类似的方式。只要提前规定好，TX和RX按照统一或者默认的规则执行即可。
可选地，在第一终端处于连接态的情况下，第一终端接收网络侧设备发送的复制功能的激活控制信令或去激活控制信令。
具体地，动态激活/去激活主要是对发送端的复制功能进行控制，以同时确保传输效果和系统效率。
可选地，在第一终端处于连接态，且第一终端的资源调度方式为模式1的情况下，第一终端接收网络侧设备发送的复制功能的激活控制信令或去激活控制信令。
具体地，在第一终端处于连接态时，尤其是处于mode1的资源调度方式，网络侧设备可以比较方便的对第一终端的复制功能进行动态激活/去激活，例如当SL链路负荷较重情况下去激活，SL链路负荷较轻的情况下激活。
可选地，激活控制信令或去激活控制信令通过以下至少一项发送：媒体接入层控制单元MAC CE或物理下行控制信道PDCCH。
可选地，激活控制信令用于指示以下至少一项：
激活第一终端的复制功能；
激活目标SL RB的复制功能；
激活SL RB的目标RLC承载的复制功能；
激活目标QoS流的复制功能；
去激活控制信令用于指示以下至少一项：
去激活第一终端的复制功能；
去激活目标SL RB的复制功能；
去激活SL RB的目标RLC承载的复制功能；
去激活目标QoS流的复制功能。
具体地，动态控制信令可以采取MAC CE或者PDCCH等，携带激活或去激活该第一终端的全部复制功能，或者激活或去激活目标SL RB(例如指定SL RB)的复制功能，或者激活或去激活SL RB的特定RLC承载的功能，当第一终端接收到来自网络侧设备的激活或去激活控制信令，按照该激活或去激活控制信令进行操作。对于RX终端可以知道或者不知道激活/去激活操作，例如第一终端可以通过PC5信令向第二终端发送激活控制信令或去激活控制信令；如果不知道，意味着RX终端需要一直保持在所有载波组和所有RLC承载的监听和接收。
上述实施方式中，通过激活控制信令或去激活控制信令从而可以在SL链路上为符合需求的业务的复制传输进行动态控制，以达到高QoS和系统效率等方面的通信性能和系统性能的保障与提升。
可选地，该方法还包括：
第一终端通过PC5 RRC信令向第二终端发送配置信息。
具体地，SL单播业务由于是一对一的传输，且有较为稳定的PC5连接，因此可以采用PC5 RRC过程，由TX终端将复制功能的详细配置发送给RX终端，便于RX终端建立相应的传输通道，并且将传输通道和SL RB/PDCP实体可以很好的关联起来，RX终端把来自开启复制功能的逻辑通道的数据送到统一的PDCP实体进行重复检测和重排序，并按序递交高层。
可选地，该方法还包括：
第一终端通过PC5MAC CE信令向第二终端发送所述激活控制信令或去激活控制信令。
在SL单播的情况下，也支持动态信令，例如PC5MAC CE，进行复制功能的激活或去激活的通知，便于RX终端进行更好的接收处理。
上述实施方式中，第一终端可以将配置信息和/或动态控制信令发送给接收侧的终端，便于接收侧的终端进行更好的接收处理。
