具体实施方式
为了更好的理解本公开实施例公开的一种侧行链路逻辑信道标识的确定方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备、和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、和一个终端设备12为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
相关技术中，为了支持终端设备与终端设备之间的直接通信，引入了侧行链路通信方式。另外， PDCP复用是将一个数据包重复发送一次，这样可以重复传输，提高数据包传输的可靠性，也可以降低重复发送的时延，满足高可靠低时延要求。而在进行侧行链路通信时，如何保证PDCP复用的两个数据包使用不同的逻辑信道传输是亟待解决的问题。
本公开中，第一终端设备可以确定侧行链路无线承载(side link radio bearer，SLRB)对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识，其中，主路径关联的逻辑信道和辅路径关联的逻辑信道映射到不同的载波上或者不同的载波组上，并将SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识发送给第二终端设备，由此，可以保证PDCP复用的两个数据包使用不同的逻辑信道传输。
下面结合附图对本公开所提供的一种侧行链路逻辑信道标识的确定方法及装置进行详细地介绍。
请参见图2，图2为本公开实施例提供的一种侧行链路逻辑信道标识的确定方法的流程示意图，该方法由第一终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤201，确定SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
其中，主路径关联的逻辑信道标识可以是指用于传输原始PDCP数据包的逻辑信道的标识，辅路径关联的逻辑信道标识可以是指用于传输复制的PDCP数据包的逻辑信道的标识。
其中，主路径关联的逻辑信道与辅路径关联的逻辑信道映射到不同的载波上或者不同的载波组上。
本公开中，可以确定每个SLRB对应的主路径关联的逻辑信道和辅路径关联的逻辑信道，由于标识可以表示逻辑信道的唯一性，也即可以确定每个SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
本公开中，SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识，可以是第一终端设备直接确定的，也可以是第一终端设备基于网络设备发送的配置信息确定的，该配置信息中携带有SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
可选的，SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识，也可以是预配置的。
步骤202，向第二终端设备发送SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
其中，第二终端设备可以是与第一终端设备之间建立单播连接的终端设备，或者第二终端设备也可以是第二终端设备所在组的组内的终端设备，或者第二终端设备也可以是接收广播业务的终端设备，本公开对此不作限定。

请参见图3，图3为本公开实施例提供的另一种侧行链路逻辑信道标识的确定方法的流程示意图，该方法由第一终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤301，从已有逻辑信道标识中选择SLRB对应的主路径关联的逻辑信道标识，从预留逻辑信道标识里选择SLRB对应的辅路径关联的逻辑信道标识。
本公开中，第一终端设备可以从已有逻辑信道中选择SLRB对应的主路径关联的逻辑信道，从预留逻辑信道中选择SLRB对应的辅路径关联的逻辑信道，由于标识可以表示逻辑信道的唯一性，也即第一终端设备可以从已有逻辑信道标识中选择SLRB对应的主路径关联的逻辑信道标识，从预留逻辑信道标识里选择SLRB对应的辅路径关联的逻辑信道标识。
其中，SLRB对应的主路径关联的逻辑信道与辅路径关联的逻辑信道映射到不同的载波上或者不同的载波组上，不同SLRB对应的主路径关联的逻辑信道标识不同，不同SLRB对应的辅路径关联的逻辑信道标识不同。
比如，已有逻辑信道标识为1到10，预留逻辑信道标识为11到20，可以将标识为1的逻辑信道作为某SLRB对应的主路径关联的逻辑信道，将标识为11的逻辑信道作为某SLRB对应的辅路径关联的逻辑信道，可以将标识为2的逻辑信道作为另一SLRB对应的主路径关联的逻辑信道，将标识为12的逻辑信道作为另一SLRB对应的辅路径关联的逻辑信道。
需要说明的是，上述已有逻辑信道标识、预留逻辑信道标识等仅为示例，不应当看作为是对本公开 的限制。
步骤302，向第二终端设备发送SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
本公开中，第二终端设备可以是与第一终端设备之间建立基于PC5接口的无线资源控制(PC5-radio resource control，PC5-RRC)单播连接的终端设备，那么第一终端设备可以基于PC5-RRC信令向第二终端设备发送SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识，或者也可以通过侧行链路媒体介入控制层控制单元(Sidelink media access control control element，SL MAC CE)向第二终端设备发送SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
其中，PC5-RRC信令可以是RRC重配置侧行链路信令RRCReconfigurationSidelink信令。
可选的，SL MAC CE中可以携带一个或多个SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
由此，针对单播业务，第一终端设备可以通过PC5-RRC信令或者SL MAC CE，通知与第一终端设备之间建立PC5-RRC单播连接的第二终端设备SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。

可选的，SL MAC CE中可以携带一个或多个SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识。
由此，针对组播或广播业务，第一终端设备可以通过SL MAC CE携带SLRB对应的主路径关联的逻辑信道标识和辅路径关联的逻辑信道标识，以通知给组内其他终端设备或者接收广播业务的终端设备。

其中，主路径关联的逻辑信道的HARQ属性和辅路径关联的逻辑信道标识的HARQ属性的相同，可以是主路径关联的逻辑信道的HARQ属性与辅路径关联的逻辑信道的HARQ属性均为HARQ启用，或者也可以是主路径关联的逻辑信道的HARQ属性与辅路径关联的逻辑信道的HARQ属性均为HARQ禁用。
可选的，主路径关联的逻辑信道的HARQ属性和辅路径关联的逻辑信道标识的HARQ属性的相同，也可以是主路径关联的逻辑信道的HARQ属性缺省，而辅路径关联的逻辑信道的HARQ属性为HARQ启用或者HARQ禁用，或者辅路径关联的逻辑信道的HARQ属性缺省。
