在一些场景中,引入了基于层2的终端至网络(UE-to-Network)中继(Relay)UE,该UE-to-Network中继UE可以直接连接网络。具体的,远端终端通过UE-to-Network中继UE连接到接入网(例如gNB)和核心网(Core Network,CN)(例如5GC)。
图2示出了5G***的传输协议栈的示意性图,具体涉及远端UE(Remote UE)、层2UE-to-Network中继UE、gNB和5GC。如图2所示,远端UE可以包括以下层:网络协议(Internet Protocol,IP)、Uu-服务数据适配协议(Service Data Adaptation Protocol,SDAP)、Uu-分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)、PC5-无线链路控制(Radio Link Control,RLC)、PC5-媒体接入控制(Media Access Control,MAC)、PC5-物理(Physics,PHY)。UE-to-Network中继UE可以包括以下层:适配(Adaptation,ADAPT)、PC5-RLC、PC5-MAC、PC5-PHY、Uu-RLC、Uu-MAC、Uu-PHY。gNB可以包括以下层:Uu-SDAP、Uu-PDCP、ADAPT、Uu-RLC、Uu-MAC、Uu-PHY、N3协议栈。5GC可以包括以下层:IP、N3协议栈。
如图2所示,中继UE的适配层(ADAPT)设置在中继UE和gNB之间的Uu接口的控制面和用户面RLC层之上。Uu-SDAP、Uu-PDCP和无线资源控制(Radio Resource Control,RRC)终止在远端UE和gNB之间,RLC、MAC和PHY终止在每个链路中(包括远端UE和中继UE之间的链路以及中继UE和gNB之间的链路)。
在一些实施例中,中继UE和网络之间的链路可以称为Uu链路,Uu路径,远端UE和网络之间的直连链路也可以称为Uu链路,Uu路径,远端UE和中继UE之间的链路可以称为PC5链路,PC5路径。
对于L2UE-to-Network中继UE的上行链路:
中继UE的适配层支持接入PC5RLC信道之间的上行承载映射,用于执行中继UE和网络之间的Uu路径上的传输和接出Uu信道。对于上行链路的中继业务,同一远端UE和/或不同远端UE的不同端到端承载(例如,信令无线承载(signaling radio bearers,SRB),数据无线承载(Data Radio Bearer,DRB))可以在一个Uu RLC信道上进行N:1映射和数据复用。
中继UE的适配层包括待中继的上行业务的远端终端的标识信息和远端终端的无线承载的标识信息,以便gNB将与远端终端的无线承载相关联的特定分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)实体的接收数据分组关联起来。
对于L2UE-to-Network中继UE的下行链路:
中继UE的适配层可用于支持gNB处的下行承载映射,以通过中继UE和网络之间的Uu路径将远端终端的端到端无线承载(例如SRB,DRB)映射到Uu RLC信道。中继UE的适配层可用于支持远端UE和/或不同远端UE的多个端到端无线承载(例如SRB,DRB)和中继UE和网络之间的Uu路径上的Uu RLC信道之间的下行N:1承载映射和数据复用。
中继UE的适配层包括待中继的下行业务的远端终端的标识信息。远端终端的无线承载的标识信息和远端终端的标识信息需要通过gNB放入中继UE的适配层,以便中继UE将从远端终端的无线承载接收到的数据分组映射到与该无线承载相关的PC5RLC信道。
在一些场景中,远端UE可以通过多条路径连接到网络,例如,该多条路径包括远端UE和网络 之间的直连路径,以及通过中继UE连接到网络的中继路径。
例如,如图3所示,远端UE可以通过中继UE连接到网络设备以及通过Uu接口直连至网络设备。其中,远端UE和中继UE之间通过PC5接口连接和通信,中继UE和网络设备之间通过Uu接口连接和通信。在一些场景中,若存在多跳中继UE,则中继UE之间通过PC5接口连接和通信,最后一条中继UE和网络设备之间通过Uu接口连接和通信。
在另一些场景中,远端UE可以通过一条路径连接到网络,例如,如图4所示,通过远端UE和网络之间的直连路径连接到网络,或者,如图5所示,远端UE通过中继UE连接到网络。
因此,在远端UE通过一条路径连接到网络时,如何切换到通过多条路径连接到网络,以及在远端UE通过多条路径连接到网络时,如何切换到通过一条路径连接到网络是一项亟需解决的问题。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
