网络设备可以用于与一个或多个终端设备进行通信，也可以用于与一个或多个具有部分终端设备功能的网络设备进行通信(比如宏基站与微基站，如接入点，之间的通信)。网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，时分同步码分多址(Time Division Synchronous Code Division Multiple Access，TD-SCDMA)系统中的基站收发台(Base Transceiver Station，BTS)，也可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来系统、新空口(NR)系统中的基站或者未来演进的PLMN网络中的基站等。另外，网络设备也可以为接入点(Access Point，AP)、传输节点(Trans TRP)、中心单元(Central Unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能，本申请实施例并不限定
本申请实施例涉及的终端设备(Terminal)，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信。终端设备105可以是静止的，也可以是移动的。例如，终端设备105可以是用户设备、 接入终端、用户单元、用户站、移动站、远方站、远程终端、用户终端、无线通信设备或用户装置、移动设备、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元，远程单元、用户代理、移动客户端、智能手表、笔记本电脑、平板电脑或智能手环。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
中继设备可以是中继基站，例如微基站等。中继设备也可以是一个提供中继功能的终端设备。中继设备还可以是中继收发节点，用户终端设备(customer Premise Equipment，CPE)，中继收发器、中继代理，中继节点(Relaying Node，RN)，传输接收点(transmission and Reception Point，TRP)，或者中继传输接收点(relaying TRP，rTRP)等网络实体。具体实现中，中继设备可以分布在小区边缘，可扩大网络设备的覆盖范围。
在无线通信系统100中，接入链路(access link，AC)是指中继设备与终端设备之间的无线链路。该接入链路包括上行(uplink，UL)和/或下行(downlink，DL)接入链路。回传链路(backhaul link,，BH)是指网络设备与中继设备之间的无线链路，或者中继设备和中继设备之间的链路。该回传链路包括上行和/或下行回传链路。
应理解，本申请对网络设备和中继设备、两个中继设备之间的链路名称、以及中继设备和终端设备之间的链路名称不进行限定。此外，本申请实施例中，网络设备还可以称为“供体网络设备”。

需要说明的，图1示出的无线通信系统100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
图2示出了本申请实施例的一种应用场景的示意图。图2所示的无线通信系统200包括网络设备210、网络设备220、中继设备230、中继设备240、终端设备250和终端设备260。若中继设备230已经与网络设备210建立了连接，中继设备240接入中继设备230，则中继设备240成为中继设备230的下级节点，这样对于中继设备240在如图2所示的结构中可以称为“多跳中继结构”。此外，若中继设备240与网络设备220已经建立了连接，则中继设备240也可以接入中继设备230成为中继设备230的下级节点，即对于中继设备240来说既可以处于从网络设备210、中继设备230到中继设备240的连接中，也可以处于从网络设备220到中继设备240的连接中，因此可以将该结构称为“多连接中继结构”。
应理解，本申请实施例的无线通信系统对中继设备的个数不进行限定，例如，无线通信系统可以包括3个，4个，或5个中继设备。
在多跳多连接中继结构中，回传链路1的传输稳定性决定了整个网络的系统容量，例如，若图2所示的回传链路1链路中断，则接入链路2所对应的终端设备2的数据无法转发到网络设备，只能堆积在中继设备1中。此外，中继设备2的数据也会堆积在中继设备1无法转发到网络设备。因此，在多跳多连接中继结构中，需要及时的寻找新的路由，减少在回传链路1中断带来的数据堆积，甚至丢失。
传统无线网格(mesh)网络中，当网络中的某个节点对路由有需求的情况下，由该节点发起路由请求(PREQ)消息，并在该PREQ消息中携带路由选择指标(时延、传输能力和负载等)，当mesh网络中有节点接收到该PREQ消息后，根据路由选择指标寻找能够接入网络的节点，当找到能够接入网络的节点之后，由能够接入网络的节点发起路由响应(PREP)消息，并将PREQ消息中携带的路由指标内容反馈给路由发起节点，发起节点采用该路由指标内容指示的路由路径进行业务传输。
在IAB场景或NR系统中，由于不同的业务对时延的敏感程度不同，若统一采用上述方法获取路由路径，可能无法满足低时延的业务。例如，URLLC业务需求的时延要在0.5ms的范围内，采用上述方法获取路由路径为URLLC业务选择的路由路径可靠性较低。
图3示出了本申请实施例的用于业务传输的方法的示意性流程图。
301，第一节点在第一时刻向第二节点发送路由请求，该路由请求用于为至少一种业务请求路由路径。
具体地，该路由请求可以是在一种业务需求路由路径的情况下发送的，也可以是在多种业务都需求路由路径的情况下发送的。
可选地，第一节点可以在与上级节点的链路中断，或者在与上级节点的链路拥塞，或者第一节点其他有需要新的路由路径的需求的情况下，向第二节点发送路由请求。
具体地，第一节点记录第一节点发送路由请求的发送时刻，即第一时刻。
例如，如图4所示，第一节点可以是rTRP1，也可以是rTRP2。
相应地，在第一节点为rTRP1时，第二节点可以是rTRP2；在第一节点为rTRP2时，第二节点为rTRP3。
可选地，路由请求可以是第一节点主动发送的，也可以是其他节点触发该第一节点发送。例如，如图4所示，在第一节点为rTRP2的情况下，rTRP2在接收到rTRP1发送的路由请求1才会向rTRP3发送路由请求2。
302，第二节点根据该路由请求，获取路由路径。
具体地，该路由路径可以是能够用于为该第二节点提供服务的路由路径，或者说该路由路径能够连接到网络设备。
可选地，该路由请求可以只具有触发作用，即第二节点接收到该路由请求后，立即启动获取路由路径。
可选地，第二节点可以检测并获得该第二节点的路由路径。
具体地，第二节点可以检测自己是否具有能够为业务提供服务的路由路径，在检测到自己能够为业务提供服务的情况下，即第二节点获得了路由路径。
可选地，第二节点也可以将该路由请求转发给第三节点，第三节点根据该路由请求，检测并获得能够为业务提供服务的路由路径。
具体地，第二节点向第三节点发送路由请求，第三节点接收到该路由请求检测自己是 否具有能够为业务提供服务的路由路径。在检测到自己具有能够为业务提供服务的路由路径的情况下，即获得了能够为业务提供服务的路由路径。
例如，如图4所示，第一节点为rTRP1，rTRP1向rTRP2发送路由请求1，rTRP2向rTRP3发送路由请求2，rTRP3能够连接gNB2，则rTRP3向rTRP2反馈路由响应消息2，rTRP2向rTRP1反馈路由响应消息1。
需要说明的是，第一节点向第二节点发送的路由请求，与第二节点向第三节点发送的路由请求的帧结构可以不相同。
应理解，从gNB1、rTRP1、rTRP2到rTRP3之间的链路可以称为“主链接通道”，从rTRP3到gNB2之间的链路可以称为“备份通道”。
可选地，在第三节点也不具有能够为业务提供服务的路由路径的情况下，第三节点还可以向下级节点发送路由请求，下级节点还可以再向下下级节点发送路由请求，直到检测到能够为业务提供服务的路由路径为止。
可选地，第二节点可以同时进行检测自己是否具有能够为业务提供服务的路由路径的，以及向第三节点发送路由请求；或者第二节点在检测到自己不具有能够为业务提供服务的路由路径的情况下，再向第三节点发送路由请求，本申请对此不进行限定。
303，第一节点在第二时刻接收该第二节点发送的路由响应消息，该路由响应消息包括路由标识，该路由标识用于指示路由路径。
可选地，第一节点在向第二节点发送路由请求时，可以启动定时器。
可选地，第一节点可以设置预设值，在定时器达到预设值之前，接收该路由响应消息。若在定时器到达预设值之后可以不去检测路由响应消息，或者不对接收到的路由消息进行解析，从而保证了选择的路由路径的有效性。
例如，如图4所示，以rTRP2为第一节点，rTRP2在接收到rTRP1发送的路由请求1之后，向rTRP3发送路由请求2，rTRP2在发送路由请求1时启动定时器1，rTRP1设定的预设值为时间窗T1，rTRP2在发送路由请求2时启动定时器2，rTRP2设定的预设值为时间窗T2，若rTRP2在T2之前接收到路由请求响应消息2，则rTRP2找到合适的路由路径，即路由请求成功。rTRP2向rTRP1发送的路由请求响应消息1，若rTRP1接收在到达时间窗T1之后才接收到路由请求响应消息1，则该路由请求响应消息1无效，即路由请求失败。
需要说明的是，若第一节点在定时器到达预设值之前，接收到路由响应消息，第一节点可以停止该定时器的计时。
可选地，该预设值也可以是第一节点服务的业务中任意一种业务的时延需求的时延值。
例如，该预设值可以是第一节点服务的所有业务中时延需求最短的时延值。这样第一节点可以保证接收到的路由响应消息指示的路由路径能够满足第一节点能够服务的所有业务的需求。
再例如，该预设值可以是第一节点服务的所有业务的时延需求的时延值排序处于中心位置的业务的时延值，即第一节点暂时不需要为小于该时延值的业务寻找路由路径，提高了为业务选择路由路径的效率。
可选地，该预设值也可以是小于第一节点服务的所有业务中时延需求最短的时延值的任意值，或者是大于第一节点服务的所有业务中时延需求最长的时延值的任意值，本申请 对此不进行限定。
可选地，该路由响应消息还可以包括：所述路由响应消息包括所述路由标识对应的路由路径经过节点的节点信息、所述路由标识对应的路由路径经过的相邻节点之间的时延信息、所述相邻节点通信的波束对信息和所述相邻节点通信的波束对质量信息中的至少一项。
具体地，该路由响应消息还可以包括路由路径经过的所有节点的节点信息或相邻节点之间的时延信息，第一节点根据该路由响应消息包括的各级节点的节点信息和/或相邻节点之间的时延信息进行合理的判断，确定该路由路径是否满足某一种业务的需求。该路由响应消息还可以包括相邻节点通信的波束对信息或波束对质量信息，这样第一节点可以根据该波束对信息和/或该波束对质量信息确定使用该路由路径传输业务可以采用的波束对，从而更进一步的提高了业务传输的质量。
需要说明的是，相邻节点是指能够直接进行通信的两个节点。例如，如图4所示，在rTRP1与gNB1之间的链路失败，rTRP1向rTRP2发送路由请求1，rTRP2向rTRP3发送路由请求2，rTRP3检测到能够提供服务的路由路径，则通过rTRP2向rTRP1反馈路由响应消息，其中相邻节点可以是rTRP1与rTRP2之间，也可以是rTRP2与rTRP3之间。
其中，波束对信息可以是波束索引，例如信道状态资源指示(Channel State Information Reference Signal resource indicator，CRI)或者传输配置指示(transmission configuration indication，TCI)。波束对质量信息可以是参考信号接收功率(Reference Signal Received Power，RSRP)、信号噪声干扰比(Signal to Interference plus Noise Ratio，SINR)或者其他质量信息中的至少一种。
304，第一节点根据该第一时刻和该第二时刻的时间间隔，确定该路由路径服务的目标业务。
具体地，在第一节点发送路由请求是存在多种业务有路由路径需求的情况下，第一节点根据第一时刻和该第二时刻的时间间隔的时间长短，可以确定该路由路径能够服务的目标业务。这样对于不同的业务能够选择满足自己需求的路由路径，提高了为业务选择路由路径的可靠性。
此外，在多种业务都需求路由路径的情况下，第一节点可以只发送一次路由请求，并根据时间间隔确定路由响应消息携带的路由标识指示的路由路径能够为哪些业务服务，这样避免了每种业务在有路由路径需求的情况下分别发送路由请求，降低了路由请求以及响应路由请求的路由响应消息之间的相互干扰。
此外，由于第一节点根据第一时刻和第二时刻的时间间隔的时间长短确定路由路径能够服务的目标业务，也就是说，第一节点可以考虑业务处理时长和空口传输时长之和与业务需求的时延进行匹配，从而使得业务能够选择到更加合理的路由路径，更进一步地为业务传输提供了保障。
例如，在第一节点发送路由请求是存在一种业务有路由路径需求的情况下，第一节点根据第一时刻和第二时刻的时间间隔的时间长短确定出满足需求的路由路径相比传统方案得到的路由路径更加合理，业务传输更进一步得到保障。
需要说明的是，该目标业务可以是该至少一种业务中的一种业务或多种业务，本申请对此不进行限定。
可选地，第一节点在获得的路由路径上传输该目标业务。
可选地，第一节点获取该至少一种业务的时延需求。
具体地，第一节点可以自己确定该至少一种业务中每种业务的时延需求，也可以是接收从上级节点发送的每种业务的时延需求。
可选地，某一种业务的时延需求可以是某一个节点从上级节点接收到该业务的时刻，到处理完成该业务并出现在下级节点空口的时刻之间的时长。也就是说，某一种业务需求的时延为业务处理时长和空口传输时长之和。这样通过精确的业务的时延需求，以及该时间间隔能够为每种业务选择到更加合理的路由路径，为不同业务的传输提供了保障。
可选地，第一节点可以存储有映射关系，该映射关系为至少一个时间间隔与至少一种业务的映射关系。
具体地，该映射关系可以是根据时间间隔与业务需求的时延的对应关系确定的，这样第一节点根据该映射关系可以确定出发送路由请求到接收到路由响应消息之间的时间间隔对应的业务。
可选地，第一节点也可以根据时间间隔和业务的时延需求的大小关系确定该路由路径能够服务的业务。
具体地，第一节点可以将该至少一种业务中第一业务的时延需求设定为一个预设值，第一节点可以根据时间间隔与该预设值的大小关系确定该路由路径是否能够为该第一业务提供服务。若第一节点发送路由请求的第一时刻与接收路由响应消息的第二时刻之间的时间间隔大于该预设值，则第一节点可以将该路由响应消息指示的路由路径用于为该第一业务提供服务；若时间间隔小于该预设值，则该路由路径不能用于为该第一业务提供服务。
其中，第一节点在确定获取的路由路径能够为第一业务提供服务，可以将该路由路径加入到第一业务的路由列表中；若该路由路径不能为该第一业务提供服务，则不会将该路由路径加入到该第一业务的路由列表中。
可选地，某一种业务的时延需求可以是在一个时间段的范围内，这样第一节点也可以根据第一时刻和第二时刻的时间间隔确定是否在该时间段的范围内，若该时间间隔在该时间段的范围内，则第一节点可以将该路由响应消息指示的路由路径用于为该第一业务提供服务；若该时间间隔不在该时间段的范围内，则第一节点将该路由响应消息指示的路由路径不会被选中用于为该第一业务提供服务。

应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
