为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、NR旁链路简介
上述旁链路也可称为副链路、侧链路，边链路等。Sidelink传输，即用户设备(User Equipment，UE)之间直接进行通信，如图2所示。LTE Sidelink是基于广播进行通讯的，可用于支持车联网(Vehicle to Everything，V2X)的基本安全类通信，但不适用于其他更高级的V2X业务。第5代(5th Generation，5G)NR系统支持更加先进的Sidelink传输设计，例如，单播、多播或组播等，从而可以支持更全面的业务类型。
旁链路通信支持两种资源分配模式，分别是调度资源分配(Scheduled Resource Allocation)模式与自主资源选择(Autonomous Resource Selection)模式。前者由网络侧设备控制并为每个UE分配资源，后者由UE自主选择资源。
NR的旁链路通信对传输的内容通过旁链路数据无线承载(Sidelink Data Radio Bearer，SL-DRB)和旁链路信令无线承载(Sidelink Signal Radio Bearer，SL-SRB)做了区分。其中SL-DRB与服务质量(Quality of Service，QoS)配置文件(Profile)具有映射关系，即具有相同的QoS Profile的数据形成一个QoS流(Flow)通过一个SL-DRB传输，SL-DRB可以被预配置或重配置。而SL-SRB所使用的配置信息并不依据QoS框架定义，为协议规定好的参数，其中一些参数的选取也基于终端实现。
具体地，各个SL-SRB所对应的无线链路层控制(Radio Link Control，RLC)配置可以如表1和表2所示。
表1 SL-SRB0和SL-SRB4的RLC配置
表2 SL-SRB1至SL-SRB3的RLC配置

二、载波聚合(Carrier Aggregation，CA)简介
载波聚合是将2个或更多的载波单元(Component Carrier，CC)聚合在一起以支持更大的传输带宽。实际上，每个载波单元对应一个独立的小区，通常可以将1个载波单元等同于1个小区。为了高效地利用零碎的频谱，载波聚合支持不同载波单元之间的聚合，具体可以包括如下载波单元：同一频带内，邻接或非邻接的载波单元；不同频带内的载波单元。
三、LTE Sidelink载波聚合简介
从第十五个发布版本开始，LTE支持旁链路载波聚合(Sidelink Carrier Aggregation，SL-CA)。与空口(即下行链路(Downlink)与上行链路(Uplink))不同，SL-CA的载波不区分主载波(Primary Component Carrier，PCC)与辅载波(Secondary Component Carrier，SCC)。
每个配置或者预配置的用于旁链路通信发送或接收的资源池都关联到单个载波。当支持SL-CA的UE使用模型2(Mode2)自主资源选择时，首先进行载波选择并选择一个或多个用于旁链路通信的载波。基于载波的信道占有率(Channel Busy Ratio，CBR)和待传输V2X消息的接近业务单个包优先级(ProSe per-packet Priority，PPPP)，终端的媒体接入控制(Media Access Control，MAC)实体进行载波选择。当资源重选被触发时，执行载波重选。为了避免在不同载波之间频繁切换，如果在该载波上测量的CBR低于预配置或者配置的阈值，则UE可以继续使用已选择的载波进行传输。所有选择的载波应该具有相同的同步参考或相同的同步优先级配置。对于使用Mode2自主资源选择的终端，基于在载波上测量的CBR和对应的旁链路逻辑信道(SL-Logical Channel，SL LCH)的PPPP，针对每个旁链路资源执行逻辑信道优先化(Logical Channel Prioritization，LCP)。
四、LTE Sidelink PDCP duplication机制简介
LTE旁链路通信支持在PDCP层进行包复制从而达到冗余传输的目的。一个PDCP实体产生两个相同的PDCP服务数据单元(Service Data Unit，SDU)并分别递交至两个RLC实体，并且两个相同的PDCP SDU只能被传输在两个不同的载波上。终端可以基于预配置或配置的接近业务单个包可靠性(ProSe Per-Packet Reliability，PPPR)门限(threshSL-Reliability)而进行冗余传输的激活和去激活，即，当所传输数据的PPPR低于上述PPPR门限，则激活PDCP duplication；否则去激活PDCP duplication。对于LTE的旁链路通信，并未区分信令与数据承载，所有被传输的信息都被旁链路无线承载(Sidelink Radio Bearer，SLRB)承载并通过旁链路数据信道(Sidelink Traffic Channel，STCH)。
对于Mode 1(即调度资源分配)以及Mode 2(即自主资源选择)，终端对一些达到配置的PPPR阈值的数据包进行冗余传输。对于Mode 1，终端通过旁链路缓存状态报告(Sidelink Buffer Status Report，SL-BSR)上报与一或多个PPPR值关联的数据量以及其目的地，(即Destination Layer-2 ID，可以是一个UE，也可以是多个UE)。基于此，基站可以 配置PPPR值和逻辑信道组(Logical Channel Group，LCG)的映射关系，并且可以在SL-BSR中通过PPPR值可以被关联的LCG ID反映。连接态终端可以通过旁链路终端信息(Sidelink UE Information，SUI)向基站上报一个PPPR值列表。
对于使用Mode 1的终端，基站为每个目的地配置两个不重叠的载波集合。UE将分别对应于相同PDCP实体的两个SL-LCH与为这两个SL-LCH的目标配置的两组载波集合相关联。具体的关联方法取决于终端的实现。每个SL-LCH的数据只能在与其关联的载波集合中的载波上传输。
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旁链路无线信令承载传输方法进行详细地说明。
请参见图3，图3是本申请实施例提供的一种旁链路无线信令承载传输方法的流程图，该方法可以由第一终端执行，如图3所示，包括以下步骤：
步骤301、第一终端确定第一目标配置信息；
步骤302、所述第一终端根据所述第一目标配置信息进行SL SRB的传输；
其中，所述第一目标配置信息包括如下至少一项：

第一条件信息，所述第一条件信息包括激活SL SRB的PDCP复制的条件信息；
载波信息，所述载波信息用于指示传输SL SRB的PDCP复制包的载波。
本实施例中，上述激活PDCP复制(duplication)也可以称为激活PDCP duplication功能或者激活SL SRB的PDCP duplication机制等。此外，上述激活PDCP复制也可以称为触发PDCP复制或者开启PDCP复制或者启动PDCP复制等。上述PDCP复制包可以理解为激活了PDCP复制的SL SRB的PDCP实体生成的包，例如，PDCP SDU。
上述SL SRB配置信息用于配置至少一个SL SRB的PDCP复制，其中，上述SL SRB配置信息可以包括但不限于SL SRB的PDCP配置信息、SL SRB的RLC配置信息、是否激活SL SRB的PDCP复制的指示信息、SL SRB是否支持PDCP复制的指示信息等中的至少一项。
上述第一条件信息包括激活SL SRB的PDCP复制的条件信息，例如，上述第一条件信息可以包括激活SL SRB的PDCP复制的条件参数(例如，旁链路信道质量指标(例如，旁链路信道忙碌率、旁链路参考信号接收功率、旁链路接收信号强度指示等)的阈值)和激活条件(例如，SL SRB所传输信息对应的旁链路信道质量指标的值不高于旁链路信道质量指标的阈值)等中的至少一项。在一些可选的实施例中，在上述第一条件信息仅包括激活SL SRB的PDCP复制的条件参数的情况下，上述激活SL SRB的PDCP复制的条件参数可以用于隐式地指示激活SL SRB的PDCP复制的条件，例如，在上述第一条件信息包括旁链路信道质量指标的阈值的情况下，则隐式地指示激活SL SRB的PDCP复制的条件为SL SRB所传输信息对应的旁链路信道质量指标的值不高于旁链路信道质量指标的阈值。
上述载波信息用于指示传输SL SRB的PDCP复制包的载波，例如，上述载波信息可以 用于指示在SL SRB的PDCP复制激活的情况下用于传输该SL SRB的PDCP实体生成的PDCP SDU的RLC实体对应的旁链路逻辑信道可用的载波集合。其中，上述载波信息可以是基于终端的粒度指示传输SL SRB的PDCP复制包的载波集合，在该情况下同一终端的所有SL SRB共用该载波集合传输PDCP复制包，例如，上述载波信息可以包括第一终端的载波信息，第一终端的载波信息所指示的载波集合用于传输第一终端的所有SL SRB的PDCP复制包；或者上述载波信息可以是基于SL SRB的粒度指示传输SL SRB的PDCP复制包的载波，在该情况下，每个SL SRB分别存在与其对应的载波信息，例如，上述载波信息可以包括至少一个SL SRB的每个SL SRB对应的载波信息，每个SL SRB对应的载波信息所指示的载波集合用于传输该SL SRB的PDCP复制包。
需要说明的是，上述第一目标配置信息可以由协议预定义，或者上述第一目标配置信息可以由网络侧设备配置，或者上述第一目标配置信息可以由第二终端配置，或者上述第一目标配置信息的部分配置信息由协议预定义，上述第一目标配置信息的另一部分配置信息由网络侧设备配置等。其中，第二终端可以为与第一终端进行旁链路通信的任意终端。
示例性的，第一终端在确定第一目标配置信息之后，可以基于第一目标配置信息进行SL SRB的PDCP复制配置，进而可以基于经过PDCP复制配置的SL SRB传输信令。
本申请实施例提供的旁链路无线信令承载传输方法，第一终端确定第一目标配置信息，并根据所述第一目标配置信息进行SL SRB的传输；其中，所述第一目标配置信息包括如下至少一项：SL SRB配置信息，所述SL SRB配置信息用于配置至少一个SL SRB的PDCP复制；第一条件信息，所述第一条件信息包括激活SL SRB的PDCP复制的条件信息；载波信息，所述载波信息用于指示传输SL SRB的PDCP复制包的载波，也即本申请实施例提供了一种实现NR的SL通信的冗余传输的控制方式，即基于第一目标配置信息进行SL SRB的冗余传输控制，有利于提高NR的SL通信的可靠性。
可选地，所述SL SRB配置信息包括如下至少一项：
所述至少一个SL SRB的每个SL SRB的标识；
所述至少一个SL SRB的每个SL SRB的PDCP配置信息，所述SL SRB的PDCP配置信息包括第一指示域，所述第一指示域用于指示激活所述SL SRB的PDCP复制；
所述至少一个SL SRB的每个SL SRB的至少一个RLC配置信息，所述SL SRB的RLC配置信息用于配置用于传输所述SL SRB的PDCP复制包的至少一个RLC实体。
上述SL SRB的标识可以包括但不限于上述SL SRB的名称，例如，SL SRB0、SL SRB1、SL SRB2、SL SRB3、SL SRB4等，其中，上述SL SRB0、SL SRB1、SL SRB2、SL SRB3、SL SRB4可以是相关技术中的协议定义的名称。
在一些可选地实施例中，上述SL SRB的标识还可以用于指示激活该SL SRB的PDCP复制。例如，第一终端在收到至少一个SL SRB的标识的情况下激活该至少一个SL SRB的PDCP复制。
上述每个SL SRB的PDCP配置信息分别可以用于配置该SL SRB的PDCP实体，其 中，上述每个SL SRB的PDCP配置信息均包括第一指示域，分别用于指示激活该SL SRB的PDCP复制。例如，SL SRB0的PDCP配置信息可以用于配置该SL SRB0的PDCP实体，SL SRB0的PDCP配置信息包括的第一指示域用于指示激活该SL SRB0的PDCP复制；SL SRB1的PDCP配置信息可以用于配置该SL SRB1的PDCP实体，SL SRB1的PDCP配置信息包括的第一指示域用于指示激活该SL SRB1的PDCP复制。也就是说，本实施例通过每个SL SRB的PDCP配置信息的第一指示域显示地指示激活该SL SRB的PDCP复制。
上述每个SL SRB的每个RLC配置信息分别用于配置用于传输该SL SRB的PDCP复制包的至少一个RLC实体。例如，SL SRB3的RLC配置信息用于配置在该SL SRB3的PDCP复制激活的情况下用于传输该SL SRB3的PDCP实体生成的PDCP SDU的至少一个RLC实体，SL SRB4的RLC配置信息用于配置在该SL SRB4的PDCP复制激活的情况下用于传输该SL SRB4的PDCP实体生成的PDCP SDU的至少一个RLC实体。
示例性的，上述每个SL SRB可以包括一条RLC配置信息，该SL SRB的所有RLC实体共用该RLC配置信息；或者，上述每个SL SRB可以包括该SL SRB的各个RLC实体对应的RLC配置信息。其中，上述RLC配置信息可以包括但不限于如下至少一项：RLC传输模式(即rlc-TransmissionMode)，序列号(Serial Number，SN)域长度(即sn-FieldLength)，重组定时器参数(即t-Reassembly)，轮询重传定时器参数(即t-PollRetransmit)，轮询协议数据单元(Protocol Data Unit，PDU)参数(即pollPDU)，轮询字节参数(即pollByte)，最大重传阈值(即maxRetxThreshold)，状态禁止定时器参数(即t-StatusProhibit)，逻辑信道标识(即logicalChannelIdentity)。
在一些可选地实施例中，可以通过上述每个SL SRB的RLC配置信息隐式地指示是否激活该SL SRB的PDCP复制，例如，在某一SL SRB包括多条RLC配置信息的情况下激活该SL SRB的PDCP复制。
以下结合举例对激活SL SRB的PDCP复制进行说明。
情况一，在第一目标配置信息仅包括SL SRB配置信息的情况下，第一终端可以基于SL SRB配置信息确定激活PDCP复制的至少一个SL SRB，例如，第一终端在收到至少一个SL SRB的每个SL SRB的标识的情况下激活该至少一个SL SRB的PDCP复制。
情况二，在第一目标配置信息包括第一条件信息的情况下，第一终端可以基于第一条件信息确定激活所有SL SRB的PDCP复制，例如，第一终端在接收到第一条件信息的情况下，在任意SL SRB满足上述第一条件信息所指示的激活PDCP复制的条件的情况下激活该SL SRB的PDCP复制。
情况三，在第一目标配置信息包括SL SRB配置信息和第一条件信息的情况下，第一终端可以基于SL SRB配置信息确定支持PDCP复制的至少一个SL SRB，并基于上述第一条件信息确定激活上述支持PDCP复制的至少一个SL SRB中的部分或者全部SL SRB的PDCP复制，例如，上述SL SRB配置信息指示SL SRB1和SL SRB3支持PDCP复制，则第一终端可以在确定SL SRB1满足上述第一条件信息所指示的激活PDCP复制的条件的情况下激 活SL SRB1的PDCP复制，在确定SL SRB3满足上述第一条件信息所指示的激活PDCP复制的条件的情况下激活SL SRB3的PDCP复制。
可选地，所述RLC配置信息包括如下至少一项：协议预定义的第一RLC配置信息，从网络侧设备接收的第二RLC配置信息，从第二终端接收的第三RLC配置信息；
其中，所述第二终端为与所述第一终端进行旁链路通信的终端。
在一实施方式中，可以由协议预定义用于配置用于传输SL SRB的PDCP复制包的RLC实体的RLC配置信息(即上述第一RLC配置信息)，在该情况下，对于各个终端所有激活PDCP复制的SL SRB，均可以使用上述协议预定义的RLC配置信息配置用于传输其PDCP复制包的RLC实体，也就是说，对于各个终端的各个SL SRB冗余传输中的两个RLC实体均采用上述协议预定义的RLC配置信息进行配置，这样不仅可以较为有效的保证有利于保证进行旁链路通信的终端之间的RLC配置的一致性，还可以节省配置信令的资源开销。例如，对于SL SRB0和SL SRB4，可以采用如表1所示的RLC配置信息进行RLC配置，对于SL SRB1至SL SRB3，可以采用如表2所示的RLC配置信息进行RLC配置。
在一些可选地实施例中，上述第一RLC配置信息可以包括如下至少一项：RLC传输模式，SN域长度，重组定时器参数，轮询重传定时器参数，轮询PDU参数，轮询字节参数，最大重传阈值，状态禁止定时器参数，逻辑信道标识。
在另一实施方式中，可以由网络侧设备配置用于传输SL SRB的PDCP复制包的RLC实体的RLC配置信息(即上述第二RLC配置信息)，例如，网络侧设备可以针对每个激活PDCP复制的SL SRB，为其配置用于传输该SL SRB的PDCP复制包的RLC实体的RLC配置信息，这样可以提高SL SRB的RLC配置的灵活性。
在一些可选地实施例中，上述第二RLC配置信息可以包括如下至少一项：RLC传输模式，SN域长度，重组定时器参数，轮询重传定时器参数，轮询PDU参数，轮询字节参数，最大重传阈值，状态禁止定时器参数，逻辑信道标识。
需要说明的是，上述网络侧设备的数量可以为一个或者多个，在上述网络侧设备的数量为多个的情况下，也就是说，第一终端可以从多个网络侧设备(例如，基站)接收针对同一SL SRB的第二RLC配置信息，得到针对同一SL SRB的多个第二RLC配置信息。
还需要说明的是，在一些可选地实施例中，在网络侧设备为第一终端配置了上述第二RLC配置信息的情况下，第一终端可以基于实现自行配置除RLC传输模式和SN域长度之外的RLC配置，也就是说，第一终端可以仅应用网络侧设备配置的RLC传输模式和SN域长度，而可以不采用网络侧设备配置的其他配置参数项(即除RLC传输模式和SN域长度之外的配置参数项)配置用于传输SL SRB的PDCP复制包的RLC实体。
在又一实施方式中，第一终端可以从与其进行旁链路通信的对端设备(即第二终端)接收用于配置用于传输SL SRB的PDCP复制包的RLC实体的RLC配置信息(即第三RLC实体配置信息)，这样不仅可以提高SL SRB的RLC配置的灵活性，还有利于保证第一终端与第二终端之间的RLC配置的一致性。
在一些可选地实施例中，上述第三RLC配置信息可以包括如下至少一项：RLC传输模式，SN域长度，重组定时器参数，轮询重传定时器参数，轮询PDU参数，轮询字节参数，最大重传阈值，状态禁止定时器参数，逻辑信道标识。
需要说明的是，上述第一RLC配置信息、第二RLC配置信息和第三RLC配置信息所包括的RLC参数项可以全部相同或者部分相同或者完全不相同。其中，上述RLC参数项可以包括但不限于RLC传输模式、SN域长度、重组定时器参数、轮询重传定时器参数、轮询PDU参数、轮询字节参数、最大重传阈值、状态禁止定时器参数和逻辑信道标识中的至少一项。
还需要说明的是，上述三种RLC配置方式可以根据需要进行合理组合。示例性的，若某一SL SRB的RLC配置信息包括上述第一RLC配置信息、第二RLC配置信息和第三RLC配置信息中的至少两项的情况下，第一终端可以根据上述第一RLC配置信息、第二RLC配置信息和第三RLC配置信息中的至少两项配置用于传输该SL SRB的PDCP复制包的RLC实体，例如，在该SL SRB的RLC配置信息包括上述第一RLC配置信息和第二RLC配置信息的情况下，若上述第一RLC配置信息和第二RLC配置信息所包括的RLC参数项不同，在可以综合上述第一RLC配置信息和第二RLC配置信息配置用于传输该SL SRB的PDCP复制包的RLC实体，若上述第一RLC配置信息和第二RLC配置信息所包括的RLC参数项相同，则可以优先使用第二RLC配置信息配置用于传输该SL SRB的PDCP复制包的RLC实体。
可选地，所述第一RLC配置信息包括如下至少一项：RLC传输模式，SN域长度，逻辑信道标识。
上述RLC传输模式可以包括但不限于确认模式(Acknowledged Mode，AM)或者非确认模式(Unacknowledged Mode，UM)等。
本实施例中第一RLC配置信息包括RLC传输模式、SN域长度和逻辑信道标识中的至少一项，这样可以保证进行旁链路通信的终端之间保证RLC传输模式、SN域长度和逻辑信道标识中的至少一项的一致性。
可选地，所述第二RLC配置信息包括第一配置信息和第二配置信息中的至少一项；
其中，所述第一配置信息包括如下至少一项：重组定时器参数，轮询重传定时器参数，轮询PDU参数，轮询字节参数，最大重传阈值，状态禁止定时器参数，逻辑信道标识；
