具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
为了便于理解，首先介绍本申请涉及的术语。
在设备到网络(UE to NW，U2N)中继场景下，远端设备可以不直接与基站连接而通过另外一个中继设备实现与基站的通信。例如，UE A可以不直接与基站连接而通过另外一个UE B的中继实现与基站的通信，其中与基站没有连接的UE A称为远端UE(remote UE)，而提供中继功能的UE B称为中继UE(relay UE)，远端UE与中继UE之间通过sidelink单播通信。其中，UE直接与基站连接称为直接链路(Direct Link)，UE通过中继UE与基站连接称为间接链路(Indirect Link)。
在设备到设备(UE to UE，U2U)中继场景下，远端设备可以通过sidelink与另一个设备进行通信，也可以通过中继设备实现两个设备之间的通信。例如，UE A可以不直接与UE B连接，而是通过UE C的中继实现与UE B的连接。其中UE A与UE C为远端UE，提供中继功能的UE B为中继UE，所有UE之间通过sidelink单播通信。其中，UE A直接与UE B保持单播连接时称为sidelink直接链路，UE A通过中继UE与UE B保持单播连接时称为sidelink间接链路。
为了更好的理解本申请实施例公开的一种控制中继设备信息发送的方法，下面首先对本申请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两个终端设备，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。图1所示的通信系统以包括一个网络设备101和两个终端设备UE(如第一终端设备102和第二终端设备103)为例。
值得说明的是，在图1所示的无线通信系统中，第一终端设备102和第二终端设备103通过Sidelink直连链路通信。在一些实施方式种，第一终端设备102可以不直接与网络设备101连接而通过第二终端设备103的中继实现与网络设备101的通信，其中，与网络设备101没有连接的第一终端设备102称为 远端UE(remote UE)，提供中继功能的第二终端设备103称为中继UE(relay UE)，远端UE与中继UE之间通过Sidelink单播通信，这种架构称为U2N(UE to NW，终端设备到网络)中继。
在一些实施方式中，第一终端设备102与网络设备101可以建立直接链路(Direct Link)以及间接链路(Indirect Link)。其中，直接链路为第一终端设备102与网络设备101直接连接的链路，间接链路为第一终端设备102通过第二终端设备103与网络设备101间接连接的链路，需要说明的是，这里的第一终端设备102作为远端UE，第二终端设备103作为中继UE。这样，远端UE可以同时通过直接链路和间接链路与网络设备保持连接，这种功能称为多路径连接(Multipath)，可以使得远端UE支持多路径传输，从而可以提高传输速率和传输可靠性。需要说明的是，远端UE必须处于连接态才能支持多路径连接。
还需要说明的是，第一终端设备102作为远端UE，第二终端设备103作为中继UE。其中，远端UE的承载可以只通过直接路径传输，称为直接承载(Direct Bearer)，也可以只通过间接路径传输，称为间接承载(Indirect Bearer)，也可以同时通过直接路径和间接路径传输，称为多路径承载(Multipath Bearer)。远端UE直接连接的小区和中继UE连接的小区可以相同也可以不同。
需要说明的是，本申请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。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。
本申请实施例中的网络设备101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。本申请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。本申请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。
本申请实施例中的终端设备102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。本申请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。
在侧链路通信中，存在4种侧链路传输模式。侧链路传输模式1和侧链路传输模式2用于终端设备直通(Device-To-Device，D2D)通信。侧链路传输模式3和侧链路传输模式4用于V2X通信。当采用侧链路传输模式3时，资源分配由网络设备101调度。具体的，网络设备101可以将资源分配信息发送给终端设备102，然后由该终端设备102向另一终端设备分配资源，以使得该另一终端设备可以通过分配到的资源向网络设备101发送信息。在V2X通信中，可以将信号较好或者可靠性较高的终端设备作为终端设备102。本申请实施例中提及的第一终端设备可以指该终端设备102，第二终端设备可以指该另一终端设备。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请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，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
需要说明的是，本申请中任一个实施例提供的控制中继设备信息发送的方法可以单独执行，或是结合其他实施例中的可能的实现方法一起被执行，还可以结合相关技术中的任一种技术方案一起被执行。
下面结合附图对本申请所提供的控制中继设备信息发送的方法及其装置进行详细地介绍。
请参考图2，图2为本申请实施例提供的一种控制中继设备信息发送的方法的流程示意图。该控制中继设备信息发送的方法由通信设备执行，该方法可以包括但不限于下述步骤：
S201，向中继设备发送指示信息，指示信息用于指示远端设备的状态参数，并指示所述中继设备根据远端设备的状态参数确定是否向远端设备发送系统信息。
本申请实施例中，中继设备可以为U2N中继场景下的中继设备，也可以为设备到设备U2U中继场景下的中继设备。
需要说明的是，为了提高传输速率和传输可靠性，远端设备可以同时通过直接链路和间接链路与网络保持连接，这种功能称为多路径(Multipath)传输或多路径连接。可以理解的是，远端设备处于连接态才能支持多路径传输。
在多路径传输的场景下，远端设备可以包括主路径和辅路径，也就是说，多路径传输中的直接链路和间接链路的一条可以为主路径，另一条可以为辅路径。
在远端设备配置了多路径传输，远端设备可以直接从网络设备如基站处获取系统信息，相应地中继设备无需发送系统信息给远端设备。另外，如果远端设备通过主路径连接的小区与中继设备的小区不同，则中继设备也无需发送系统信息给远端设备。可选地，系统信息可以为系统信息块1(System Information Block1，SIB1)。
为了避免中继设备在上述两种场景下仍然向远端设备发送系统信息而导致信令消耗增大的问题，本申请实施例中，通信设备可以向中继设备发送指示信息，通过该指示信息指示中继设备是否向远端设备发送系统信息。
在一些实现中，指示信息用于指示远端设备的状态参数，并指示中继设备根据远端设备的状态参数确定是否向远端设备发送系统信息。如此，中继设备在接收到指示信息后，可以确定远端设备的状态参数，并根据确定出远端设备是否满足不发送系统信息的设定条件；若满足设定条件下，中继设备可以不向远端设备发送系统信息；若未满足设定条件下，中继设备可以向远端设备发送系统信息。可选地，设定条件可以包括以下条件中的一种：
远端设备配置有多路径传输；
远端设备配置有多路径承载；
远端设备配置有多路径传输且间接链路为辅路径；以及
远端设备配置有多路径传输、间接路径为辅路径且远端设备的第一服务小区与中继设备的第二服务小区不同。
需要说明的是，远端设备的第一服务小区为远端设备当前所接入的小区，中继设备的第二服务小区为中继设备当前所接入的小区。可选地，远端设备的第一服务小区与中继设备的第二服务小区可以相同，也可以不同。其中，第一服务小区和第二服务小区可以为主小区(Primary cell，Pcell)。
本申请实施例中，通信设备向中继设备发送指示信息，指示信息用于指示远端设备的状态参数，并指示中继设备根据远端设备的状态参数确定是否向远端设备发送系统信息。通过指示信息可以指示中继设备在满足设定条件的情况下不向远端设备发送系统信息，从而可以避免无谓发送系统信息导致的信令开销。
在上述实施例中，通信设备可以是远端设备，也可以是网络侧设备。以下的实施例中，分别通过远端设备和网络侧设备的两个实施例来具体进行说明。
请参考图3，图3为本申请实施例提供的一种控制中继设备信息发送的方法的流程示意图。该控制中继设备信息发送的方法由远端设备执行，该方法可以包括但不限于下述步骤：
S301，远端设备向中继设备发送指示信息，指示信息用于指示远端设备的状态参数，并指示中继设备根据远端设备的状态参数确定是否向远端设备发送系统信息。
本申请实施例中，指示信息可以包括以下的状态参数中的至少一种：多路径指示信息、多路径承载指示信息、远端设备的间接链路的路径类型指示信息和在远端设备的主路径为直接链路时远端设备的第 一服务小区的标识。
可选地，如果指示信息包括多个状态参数时，多个状态参数可以单独发送给中继设备，也可以一起发送给中继设备。
可选地，多路径指示信息可以向中继设备指示远端设备是否配置多路径传输。在一些实现中，远端设备在确定自身配置多路径传输的情况下，向中继设备发送多路径指示信息。
远端设备的承载可以通过直接链路传输，称为直接承载(Direct Bearer)，也可以通过间接链路传输，称为间接承载(Indirect Bearer)，也可以同时通过直接链路和间接链路传输，称为多路径承载(Multipath Bearer)。
可选地，多路径承载指示信息可以向中继设备指示远端设备是否配置多路径承载。在一些实现中，远端设备在确定自身配置多路径承载的情况下，向中继设备发送多路径承载指示信息。
在多路径传输的场景下，远端设备可以包括主路径和辅路径，也就是说，多路径传输中的直接链路和间接链路的一条可以为主路径，另一条可以为辅路径。
可选地，间接链路的路径类型指示信息可以向中继设备指示间接链路是否为主路径。在一些实现中，远端设备可以确定自身的间接链路的路径类型，并向中继设备发送间接链路的路径类型指示信息。在一些实现中，路径类型指示往往是在远端设备配置有多路径传输的情况下，在确定出间接链路是否为主路径后，向中继设备发送的指示信息，相应地，中间设备在接收到的路径类型指示信息后，可以确定远端设备配置有多路径传输和间接链路是否为主路径。
