该时间信息可以是第一数据初始发送的发送时刻，例如，第一数据进入网络的时间，这样第一节点可以根据该时间信息获知当前传输第一数据已经占用的时长。第一节点也可以根据第一数据的QoS信息获知该第一数据传输需求的总时长。这样第一节点可以根据 第一数据传输需求的总时长和第一数据已经占用的时长选择更加合适的承载传输该第一数据，从而更进一步提高通信效率。
在一些可能的实现方式中，该时间信息携带在适配层中的字段中。
在第一节点为具有中继能力的节点的情况下，例如，第一节点向第二节点发送上行数据时，上行数据中的时间信息可以是在适配层中添加的。具体的，对于上行传输，对于直连终端的中继节点，中继节点添加时间信息在适配层。若时间信息为起始时刻，则直连的中继节点添加后，其余节点直接转发即可直至传输给接入网设备，若时间信息为已使用时长，则每个接收到数据的中继均需要在适配层更新已经使用的时长；或者下行数据的时间信息也可以是在适配层中添加的。接入网设备将数据发给中继节点时，将时间信息添加在适配层，类似的若为起始发送数据时间则后续节点直接转发该值，若为时长信息，则需要更新。即本申请实施例提供了一种发送时间信息的方式。
在一些可能的实现方式中，该第一节点为终端，该时间信息携带在该第一数据中的媒体访问控制控制元素MAC CE中。
该第一数据可以看作数据包，数据包中包括控制字段和数据字段，控制字段可以是MAC CE，数据字段可以指示数据的具体内容。即在第一节点为终端的情况下，本申请实施例提供了另一种发送时间信息的方式。
在一些可能的实现方式中，该时间信息还可以携带在PDCP包头或者RLC包头中，本申请实施例提供了多种其他发送时间信息的方式。
在一些可能的实现方式中，该第一数据包括一个或多个时间信息，以及对应的一个或多个业务数据。
该第一数据可以包括多种类型的业务数据，每种类型的业务数据对应一个时间信息。这样可以更精确的为第一数据配置合适的承载，更进一步提高通信效率。
在一些可能的实现方式中，该第一数据中的多个时间信息可以携带在对应的多个MAC CE中，该多个MAC CE可以携带在同一个MAC帧头之后，也可以各自携带在一个MAC帧头之后。也就是说，本申请实施例提供了多种MAC CE的格式，通过MAC CE携带该时间信息，从而实现更精确的选择合适的承载进行通信，提高了通信效率。
在一些可能的实现方式中，该方法还包括：该第一节点向第一终端发送第二配置信息，该第二配置信息用于配置该第一节点和该第一终端之间的承载。
在第一节点为具有中继功能的节点的情况下，第一节点还可以作为父节点向下级节点发送配置信息，以配置第一节点和下级节点之间的承载。这样分布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点的每个承载的上下文，从而节省了信令开销。
在一些可能的实现方式中，该第一配置信息包括承载标识、分组数据汇聚协议PDCP配置、无线链路控制RLC配置或逻辑信道配置中的至少一项。
在一些可能的实现方式中，在该第一节点从该第二节点接收该第一配置信息之前，该方法还包括：该第一节点向该第二节点发送配置请求，该配置请求用于请求配置与该第二节点之间的承载。
第一节点可以在有承载需求的情况下，向第二节点发送配置请求，以请求第一节点为该第二节点配置承载，避免了在第一节点没有承载需求的情况下，第二节点为该第一节点 发送第一配置信息，节省了功耗开销。
在一些可能的实现方式中，该第一节点为终端或中继节点。
在一些可能的实现方式中，若该第二节点拒绝接收该第三配置信息，则向接入网设备发送指示配置失败的指示信息，具体地该指示信息可以包括承载配置失败的承载标识，以指示具体哪个承载配置失败。

作为父节点的第二节点可以向作为子节点的第一节点发送该第一配置信息。这样父节点向子节点分配用于建立承载的配置信息，即分布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点的每个承载的上下文，从而节省了信令开销。
在一些可能的实现方式中，该方法还包括：该第二节点接收第三配置信息，该第三配置信息用于配置该第二节点和该第二节点的至少一个下级节点之间的承载；其中，该第二节点获取第一配置信息包括：该第二节点根据该第三配置信息，生成该第一配置信息。
在一些可能的实现方式中，该第三配置信息包括服务质量QoS信息、承载标识、PDCP配置、RLC配置或逻辑信道配置中的至少一项。
该第三配置信息中包括QoS信息，第二节点根据该QoS信息确定对应的RLC配置和/或逻辑信道配置，并将RLC配置和/或逻辑信道配置携带在第一配置信息中。换句话说，该第二节点可以根据QoS信息为第一节点配置QoS信息对应的承载，以使得第一节点能够根据数据的QoS信息，在对应的承载中进行传输，从而提高通信质量。
在一些可能的实现方式中，该第一配置信息包括承载标识、PDCP配置、RLC配置或逻辑信道配置中的至少一项。
在一些可能的实现方式中，若该第二节点拒绝接收该第三配置信息，则向接入网设备发送指示配置失败的指示信息，具体地该指示信息可以包括承载配置失败的承载标识，以指示具体哪个承载配置失败。
在一些可能的实现方式中，所述接入网设备确定所述第三配置信息包括：所述接入网设备在确定所述第一节点与所述第二节点之间不存在承载对应于第二承载的情况下，确定所述第一配置信息，所述第二承载为所述第一节点与第一终端之间的承载。
终端为第一节点的子节点，该终端和第一节点之间可以存在一个或多个第二承载。第一节点为第二节点的子节点，该第一节点与该第二节点之间可以存在一个或多个第一承载。在数据从终端发送到接入网设备时，终端可以使用该数据对应的目标第二承载发送到第一节点，第一节点有该目标第二承载对应的QoS信息，第一节点可以在该数据中添加对应的QoS信息，用于后续节点接收到数据后做承载映射。同时第一节点可以根据该数据的QoS信息选择合适的目标第一承载发送到第二节点。换句话说，第一节点和终端之间的承载，以及第一节点和第二节点之间的承载(可以称为相邻链路)可以对应于同一个QoS信息或者相似QoS，可以使得具有该QoS信息的数据从终端发送到第二节点。由于接入网设备能够获知每个节点和节点对应的下级节点的承载信息，因此，接入网设备可以获知相邻链路之间是否存在对应的承载，以确定是否向对应的节点发送该第三配置信息。本申 请实施例中接入网设备能够及时的为第一节点配置承载，提高通信效率。
在一些可能的实现方式中，在该第一节点为具有中继能力的节点的情况下，接入网设备可以在为该第一节点与该第一节点的下级节点(例如，终端)建立承载(例如目标第二承载)的过程中，检测该第一节点和该第二节点之间的承载是否存在与该目标第二承载对应的承载，避免专门配置该第一配置信息，节省了信令开销。
在一些可能的实现方式中，在所述第二节点为终端的情况下，所述第三配置信息携带在第四配置信息中，所述第四配置信息用于配置所述第二节点具有中继能力。
接入网设备可以在配置该第二节点作为中继节点时，例如，在向第二节点发送用于配置该第二节点具有中继能力的第二配置信息时，通过该第四配置信息携带该第一配置信息，避免专门配置该第一配置信息，节省了信令开销。

作为父节点的第二节点可以向作为子节点的第一节点发送该第一配置信息。这样父节点向子节点分配用于建立承载的配置信息，即分布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点的每个承载的上下文，从而节省了信令开销。
在一些可能的实现方式中，该方法还包括：该接入网设备向该第一节点发送第一配置信息，该第一配置信息用于配置第一节点和该第二节点之间的承载，该第二节点用于为该第一节点和该接入网设备之间提供中继通信服务；该接入网设备向该第二节点发送该第一配置信息。
在该第一节点从接入网设备接收到该第一配置信息的情况下，该接入网设备也可以将该第一配置信息发送给第二节点，以使得第一节点的父节点(第二节点)能够获知子节点的承载，即第二节点能够获知与下级节点之间的承载配置，从而提高通信效率。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统、设备到设备(device to device，D2D)通信系统或新无线(New Radio，NR)、车对外界的信息交换(vehicle to everything，V2X)、LTE-V、车与车(vehicle to vehicle，V2V)、车联网、机器类型通信(machine-type communications，MTC)、物联网(internet of things，IoT)、LTE-M，机器与机器(machine to communications，M2M)，物联网等等。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。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。
本申请实施例中的接入网设备可以是用于与终端设备通信的设备，该接入网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)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，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，或者该接入网设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的接入 网设备或者未来演进的PLMN网络中的接入网设备等，本申请实施例并不限定。
在NR中，基站的功能被分为两部分，称为集中式单元(centralized unit,CU)-分布式单元(distributed unit,DU)分离。从协议栈的角度来看，CU包括了LTE基站的RRC层和PDCP层，DU包括了LTE基站的无线链路控制(radio link control,RLC)层、媒体访问控制(media access control,MAC)层和物理(physical,PHY)层。在普通的5G基站部署中，CU和DU物理上可以通过光纤连接，逻辑上存在一个专门定义的F1接口，用于CU与DU之间进行通信。从功能的角度来看，CU主要负责无线资源控制与配置，跨小区移动性管理，承载管理等。DU主要负责调度，物理信号生成与发送。
本申请实施例中的中继节点可以是中继基站，例如微基站等。中继节点也可以是一个提供中继功能的终端设备。中继节点还可以是中继收发节点，用户终端设备(customer premise 3quipment，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，中继节点可以分布在小区边缘，可扩大网络设备的覆盖范围。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
下面将本申请涉及的术语进行介绍：
回传(backhaul，BH)链路：
中继通信系统中包括接入接入网设备、中继节点和终端。其中，接入接入网设备和中继设备之间的链路可以称为BH链路，中继设备和终端设备之间的链路可以称为“接入(access，AC)链路”。接入链路包括上行接入链路和下行接入链路。上行接入链路也被称为接入链路的上行传输，下行接入链路也被称为接入链路的下行传输。此外，两个中继节点之间的链路也可以称为“回传链路”。
应理解，本申请实施例的通信系统对中继节点的个数不进行限定，例如，通信系统可以包括4个，或5个中继节点。
还应理解，本申请对接入网设备和中继节点之间、两个中继节点之间的链路、以及中继节点和终端之间的链路名称不进行限定。
QoS：
QoS指一个网络能够利用各种基础技术，为指定的网络通信提供更好的服务能力,是网络的一种安全机制，是用来解决网络延迟和阻塞等问题的一种技术。
QoS分类标识(QoS class identifier，QCI)：
QCI是一个标度值，用于衡量包转发行为，例如，丢包率，包延迟预算。它同时应用于保证比特速率(guranteed bit rate，GBR)和Non-GBR承载，用于指定访问节点内定义 的控制承载级分组转发方式(如调度权重、接纳门限、队列管理门限、链路层协议配置等)，这些都由运营商预先配置到接入网设备中。
保证比特速率(guranteed bit rate，GBR)：
所谓GBR，是指承载要求的比特速率被网络“永久”恒定的分配，即使在网络资源紧张的情况下，相应的比特速率也能够保持。最大比特速率(maximum bit rate，MBR)参数定义了GBR承载在资源充足的条件下，能够达到的速率上限。MBR的值必须大于或等于GBR的值。相反的，Non－GBR指的是在网络拥挤的情况下，业务(或者承载)需要承受降低速率的要求，由于Non－GBR承载不需要占用固定的网络资源，因而可以长时间地建立。而GBR承载一般只是在需要时才建立。
图1是本申请一个通信系统的示意图。在无线通信系统100中，中继节点103可用于为该至少一个终端105与接入网设备101提供中继服务。其中，中继节点103的数目可以是一个，也可以是多个，即多个中继节点同时为第一终端设备和接入网设备提供中继服务。或者说多个中继节点为接入网设备提供中继服务，例如，接入网设备101需要通过中继节点103、中继节点107与终端105进行通信。
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。
可选地，中继节点可以是终端类型的节点。这样，中继节点103和中继节点107之间，以及中继节点107和终端105之间可以通过边链路(sidelink)(也称为PC5口)进行通信。
传统方案中，在多跳网络场景中，接入网设备为每个中继节点或终端发送配置信息，该配置信息用于指示中继节点或终端与各自的上级节点或下级节点建立承载。其中，传统方案中的中继节点通常为接入网设备，随着业务特性的需求，目前中继节点可以是终端设备，即终端也具有中继功能。但是在终端具有中继功能，以及结合上述传统方案的场景中，承载配置的方式信令开销比较大。
图2示出了本申请实施例的中继通信的方法的示意性流程图。
201，接入网设备确定第三配置信息，该第三配置信息用于配置第二节点与至少一个下级节点之间的承载。
具体地，接入网设备可以通过第三配置信息使得第二节点配置该第二节点与下级节点通信的承载。第二节点与某个下级节点之间的承载可以是用于该下级节点和第二节点进行通信的通道。
应理解，第二节点的下级节点可以是一个，也可以是多个。
在一个实施例中，步骤201可以是该接入网设备从核心网设备接收该第三配置信息。相应地，该核心网设备向该接入网设备发送该第三配置信息。也就是说，第三配置信息可以是由核心网设备触发的。
应理解，接入网设备可以不解析该第三配置信息，即透传该第三配置信息。
在另一个实施例中，该接入网设备可以生成该第三配置信息。也就是说，接入网设备可以自己触发生成该第三配置信息。
可选地，该第三配置信息包括QoS信息。
具体地，QoS信息可以用于指示数据需求的通信质量。
可选地，该QoS信息包括分配和保持优先级(allocation and retention priority，ARP)，GBR，最大比特速率(maximum bit rate，MBR)，每接入点(access point name，APN)最大汇聚比特速率(perAPN aggregation maximum bit rate，AMBR)，通信质量标识(5G QoS Identifier，5QI)，QCI，反射QoS属性(reflective QoSattribute，RQA)，数据承载(data radio bearer，DRB)配置中的分组数据汇聚协议(packet data convergence protocol，PDCP)配置中的至少一项。
202，该接入网设备向该第二节点发送该第三配置信息。相应地，该第二节点接收该接入网设备发送的该第三配置信息。
具体地，接入网设备接收到该第三配置信息后可以向第二节点发送该第三配置信息。
可选地，该第二节点可以是具有中继功能的终端，也可以是中继节点，或者接入回传一体化(integrated access backhaul，IAB)节点。
可选地，若该第二节点拒绝接收该第三配置信息，则向接入网设备发送指示配置失败的指示信息，具体地该指示信息可以包括承载配置失败的承载标识，以指示具体哪个承载配置失败。
应理解，该承载配置失败的承载标识可以通过列表表示。
需要说明的是，该接入网设备向该第二节点发送的第三配置信息也可以称为“无线承载建立请求(radio bearer setup request-IAB)”。
在一个实施例中，接入网设备可以在确定该第一节点与该第二节点之间不存在承载对应于第二承载的情况下，向该第二节点发送该第一配置信息，该第二承载为该第一节点与终端之间的承载，该终端为第一节点的子节点。
具体地，终端为第一节点的子节点，该终端和第一节点之间可以存在一个或多个第二承载。第一节点为第二节点的子节点，该第一节点与该第二节点之间可以存在一个或多个第一承载。在数据从终端发送到接入网设备时，终端可以使用该数据对应的目标第二承载发送到第一节点，第一节点有该目标第二承载对应的QoS信息，第一节点可以在该数据中添加对应的QoS信息，用于后续节点接收到数据后做承载映射。同时第一节点可以根据该数据的QoS信息选择合适的目标第一承载发送到第二节点。换句话说，第一节点和终端之间的承载，以及第一节点和第二节点之间的承载(可以称为相邻链路)可以对应于同一个QoS信息或者相似QoS，可以使得具有该QoS信息的数据从终端发送到第二节点。由于接入网设备能够获知每个节点和节点对应的下级节点的承载信息，因此，接入网设备可以获知相邻链路之间是否存在对应的承载，以确定是否向对应的节点发送该第三配置信息。通过上述qos与承载映射的方式，无需为每个UE的每个承载在各个节点建立承载相关的配置，而是利用每两个节点之间现有的承载与qos对应的关系，将UE的不同qos的数据映射到不同节点之间的承载上，这样大大减少了配置承载的信令开销，以及每个中继节点的存储量，减少了复杂度。
可选地，该第三配置信息可以具体包括对应于该目标第一承载的QoS信息，以使得该第二节点根据该QoS信息在该第二节点和第一节点之间建立该目标第一承载。
例如，如图1所示，第一节点可以是中继节点107，第二节点可以是中继节点103，终端可以是节点105，这样若接入网设备101确定中继节点103和中继节点107之间不存 在承载对应于节点105和中继节点107之间的目标第二承载，则接入网设备101向该中继节点103发送配置信息，用于该中继节点103为该中继节点107配置目标第一承载。
可选地，在该第一节点为具有中继能力的节点的情况下，接入网设备可以在为该第一节点与该第一节点的下级节点(例如，终端)建立承载(例如目标第二承载)的过程中，检测该第一节点和该第二节点之间的承载是否存在与该目标第二承载对应的承载。
需要说明的是，接入网设备还可以在为该第一节点与该第一节点的下级节点(例如，终端)建立承载(例如目标第二承载)的过程中，检测该第二节点与接入网设备之间的承载是否存在对应于该目标第二承载的承载。例如，该目标第二承载与目标QoS信息具有对应关系，接入网设备可以根据在该第二节点与接入网设备之间的承载是否存在对应于该目标QoS信息的承载，确定该第二节点与接入网设备之间的承载是否存在对应于该第二承载的承载。
在另一个实施例中，该第一配置信息可以携带在第四配置信息中，该第四配置信息用于配置该第二节点具有中继能力。
具体地，接入网设备可以在配置该第二节点作为中继节点时，例如，在向第二节点发送用于配置该第二节点具有中继能力的第四配置信息时，通过该第四配置信息携带该第一配置信息，避免专门配置该第一配置信息，节省了信令开销。
可选地，也可以在配置终端开启中继功能后或者作为中继节点后，对第二节点配置第二节点和接入网设备之间的承载。比如若配置之前只存在第一承载，则可以再配置至少一个承载，例如按照QCI，根据不同的QCI取值配置不同的承载，QCI为1对应配置第二承载，QCI为2对应配置第三承载等。当然可以按照ARP，GBR等等来配置，或者这些不同qos参数的组合配置不同承载。当然这个配置方式也适用于接入网设备配置第二节点和其子节点之间的承载。这种方式，可以一次建立多个承载，避免有数据传输时没有可以映射的承载。
可选地，若第二节点与接入网设备为直接连接(即接入网设备为第二节点的父节点)，则在接入网设备在为第二节点配置用于该第二节点和该接入网设备之间的承载的情况下，该接入网设备可以直接向该第二节点发送用于指示该第二节点和该接入网设备之间的承载的配置信息。
203，该第二节点根据该第三配置信息，生成该第一配置信息，该第一配置信息用于配置该第一节点和该第二节点之间的承载，该第二节点用于为该第一节点和接入网设备之间提供中继通信服务。
具体地，第二节点根据接入网设备配置的第三配置信息，可以生成用于配置与第一节点之间的承载的第一配置信息。
可选地，该第三配置信息中包括QoS信息，步骤203具体可以是第二节点根据该QoS信息确定对应的RLC配置和/或逻辑信道配置，并将RLC配置和/或逻辑信道配置携带在第一配置信息中。换句话说，该第二节点可以根据QoS信息为第一节点配置QoS信息对应的承载，以使得第一节点能够根据数据的QoS信息，在对应的承载中进行传输，从而提高通信质量。
可选地，该第三配置信息还可以包括承载标识(dientity，ID)、PDCP配置、无线链路控制(radio link control，RLC)配置或逻辑信道配置中的至少一项，这样第一配置信息 包括承载标识、PDCP配置、RLC配置或逻辑信道配置中的至少一项。其中RLC配置或逻辑信道配置也可以为中继根据接收到qos进行配置。
可选地，第一配置信息还可以包括QoS信息，用于指示对应建立承载的QoS。此时，可用于基站生成第三配置信息的场景，用于配置各级节点之间的承载，并使得各节点清楚对应承载的qos信息。
需要说明的是，该第三配置信息中的RLC配置或逻辑信道配置可以与第一配置信息的RLC配置或逻辑信道配置相同，也可以不同；第三配置信息中的承载标识和PDCP配置可以与第一配置信息中的承载标识和PDCP配置相同，本申请对此不进行限定。
还需要说明的是，本申请实施例中的承载可以是演进分组系统(evolved packet system，EPS)承载(bearer)，也可以是数据无线承载(data radio bearer，DRB)。相应地，承载标识可以是EPS承载ID，或DRB承载ID。
204，该第二节点向该第一节点发送该第一配置信息。相应地，该第一节点接收该第二节点发送的该第一配置信息。
具体地，作为父节点的第二节点可以向作为子节点的第一节点发送该第一配置信息。这样父节点向子节点分配用于建立承载的配置信息，即分布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点(指第一节点下级或更下级等)的每个承载的上下文，从而节省了信令开销。
应理解，该第一配置信息也可以称为“无线资源控制(radio resource control，RRC)重配置信息(reconfig-IAB)”。
可选地，该步骤204可以是第二节点在完成步骤203之后进行的。
可选地，该步骤204还可以是第二节点在接收到第一节点发送的配置请求之后再进行的。
具体地，第一节点可以在有承载需求的情况下，向第二节点发送配置请求，以请求第一节点为该第二节点配置承载。例如，第一节点在与下级终端建立某一个承载(例如，第一承载)时，第一节点检测到不存在对应的第二承载，该第二承载可以是第一节点与第二节点之间的承载，则第一节点可以向第二节点发送该配置信息。即当第一节点接收到的数据或第一节点与子节点之间的承载在第一节点与第二节点之间没有时，则会主动请求，用于数据传输均有匹配的QoS。
可选地，该配置请求可以包括QoS信息，第一节点可以根据该配置请求包括的QoS信息为该第二节点配置对应的承载。
可选地，第一节点可以是具有中继功能的终端，也可以是普通终端，也可以是中继节点，或者接入回传一体化(integrated access backhaul，IAB)节点。
需要说明的是，具有中继功能的节点可以是具有中继功能的终端，即该第一节点可以是终端。
还需要说明的是，该第三配置信息可以不包括RLC配置或逻辑信道配置，即第三配置信息包括承载标识和PDCP配置。
可选地，第二节点在确定第一节点完成承载配置，可以向接入网设备发送反馈信息指示该第一节点完成配置。该反馈信息可以称为“无线承载建立响应信息(radio bearer setup reponse-IAB)”。若没有成功建立承载，则返回失败建立的承载标识。
可选地，第一节点接收的第一配置信息也可以是接入网设备发送的。这种情况下，本实施例可以不执行上述步骤201-204。
具体地，接入网设备可以直接向该第一节点发送该第一配置信息，也可以由其他中继节点转发给该第一节点，本申请对此不进行限定。或者该第二节点转发该第一配置信息，但是该第二节点并不解析该第一配置信息，即该第二节点透传该第一配置信息。在该第一节点从接入网设备接收到该第一配置信息的情况下，该接入网设备也可以将该第一配置信息发送给第二节点，以使得第一节点的父节点(第二节点)能够获知子节点的承载，即第二节点能够获知与下级节点之间的承载配置，从而提高通信效率。
应理解，本申请对接入网设备向第一节点发送该第一配置信息，与向第二节点发送该第一配置信息的先后顺序不进行限定。
205，该第一节点根据该第一配置信息，建立与该第二节点的至少一个承载。
具体地，接入网设备向第二节点发送第三配置信息，该第三配置信息用于指示为第二节点与至少一个下级节点配置的承载，这样作为父节点的第二节点可以向作为子节点的第一节点发送该第一配置信息。也就是说，父节点向子节点分配用于建立承载的配置信息，即分布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点的每个承载的上下文，从而节省了信令开销。
可选地，该第一节点为具有中继功能的节点的情况下，该第一节点还可以向终端发送第二配置信息，该第二配置信息用于配置该第一节点和终端之间的承载。
具体地，在第一节点为具有中继功能的节点的情况下，第一节点还可以作为父节点向下级节点发送配置信息，以配置第一节点和下级节点之间的承载。这样分布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点的每个承载的上下文，从而节省了信令开销。第一节点在配置子节点之前，子节点可能先发送的承载配置请求。
可选地，第一节点还可以作为父节点向下级节点发送配置信息之前，第一节点从接入网设备获得配置信息，该配置信息用于配置第一节点与至少一个下级节点的承载。
可选地，第一节点在步骤205之后，第一节点可以向该第二节点发送反馈信息，该反馈信息用于指示承载配置完成。
应理解，该反馈信息可以携带在RRC配置完成消息(RRC reconfig comple)中。
可选地，在步骤205之后，该第一节点可以从下级节点(例如，终端)接收数据，并根据数据的QoS信息，选择合适的承载进行传输。相应地，终端发送该数据。
具体地，下述实施例以第一数据为例进行说明，第一节点从终端接收到的第一数据可以包括QoS信息，或者第一节点可以根据第一数据使用的承载确定出该第一数据的QoS信息，这样第一节点根据该QoS信息从第一节点和第二节点之间已经建立的多个承载中选择第一承载，并通过选中的第一承载发送该第一数据，从而提高了通信效率。
需要说明的是，在第一数据传送到第二节点时，第二节点也可以根据QoS信息和时间时间信息确定合适的承载，以满足该业务的传输服务质量需求。
可选地，该第一数据包括时间信息，该时间信息用于指示该第一数据的初始发送时刻或该第一数据当前已传输的时长，这样第一节点根据该第一数据的QoS信息和该时间信息可以从第一节点和第二节点之间的多个承载中更加准确的选择出合适的承载，从而更进一步提高通信效率并满足业务需求。
具体地，该时间信息可以是第一数据初始发送的发送时刻，例如，第一数据进入网络的时间，这样第一节点可以根据该时间信息获知当前传输第一数据已经占用的时长。第一节点也可以根据第一数据的QoS信息获知该第一数据传输需求的总时长。这样第一节点可以根据第一数据传输需求的总时长和第一数据已经占用的时长选择更加合适的承载传输该第一数据，从而更进一步提高通信效率。或者该时间信息可以直接指示该第一数据当前已传输的时长，例如设置定时器，这样第一节点可以根据第一数据传输需求的总时长和第一数据已经占用的时长选择更加合适的承载传输该第一数据，从而更进一步提高通信效率。
需要说明的是，该第一数据还可以包括承载标识、逻辑信道标识(logical channels identification，LCID)、QCI、跳数信息、ARP、或GBR信息中的至少一项。其中，QCI可以指示封包延迟预算(packet delay budget，PDB)，该PDB可以指示数据传输需求的总时长。这些信息可放在适配层中。这些信息可以让接收的中继节点更合理的确定数据需要映射的QoS。
其中，QCI表格可以如下表1所示：
表1
Figure PCTCN2019080658-appb-000001
需要说明的是，无线通道时延可以是数据包从核心网分组数据网(packet data network，PDN))侧的SGi接口成功接收到通信终端Zd接口发送成功的传输时延。
应理解，在上行传输过程中，第一节点从终端接收到时间信息，根据该时间信息确定当前第一数据传输已经占用的时长可以是从接收到的缓冲区状态报告(buffer status report，BSR)或调度请求(scheduling request，SR)时起开始计算，或者从接入网设备发送的物理下行控制信道(physical downlink control channel，PDCCH)进行上行调度开始计算直到第一节点接收到该第一数据的时刻之间的时长，即可以确定为第一数据传输当前已经占用的时长。
还理解，在下行传输过程中，第一节点可以从接入网设备或第二节点接收第一数据，该第一数据可以携带时间信息，该时间信息可以与承载一一对应，也可以与数据一一对应，还可以与媒体访问控制(media access control，MAC)业务数据单元(service data unit，SDU)一一对应。
可选地，该时间信息可以指示相对时间，也可以是指示绝对时间。例如，具体可以是 系统帧号(system frame number，SFN)号或超帧(H-SFN)号，可以是协调世界时间(coordinated universal time，UTC)时间。相对时间可以为传输了多少帧，或者多少时分秒，绝对时间可以是具体的帧号或超帧号，或者具体的时间，某时某分某秒。
可选地，该时间信息可以在适配层的字段中。
具体地，在第一节点为具有中继能力的节点的情况下，例如，第一节点向第二节点发送上行数据时，上行数据中的时间信息可以是在适配层中添加的。具体的，对于上行传输，对于直连终端的中继节点，中继节点添加时间信息在适配层。若时间信息为起始时刻，则直连的中继节点添加后，其余节点直接转发即可直至传输给接入网设备，若时间信息为已使用时长，则每个接收到数据的中继均需要在适配层更新已经使用的时长；或者下行数据的时间信息也可以是在适配层中添加的。接入网设备将数据发给中继节点时，将时间信息添加在适配层，类似的若为起始发送数据时间则后续节点直接转发该值，若为时长信息，则需要更新。
可选地，该时间信息可以携带在媒体访问控制(media access control，MAC)-控制元素(control element，CE)。
具体地，若第一节点为终端的情况下，或者是终端向第一节点发送第一数据，该第一数据携带时间信息，该第一数据可以看作数据包，数据包中包括控制字段和数据字段，控制字段可以是MAC CE，数据字段可以指示数据的具体内容。也可以是下行传输时，基站在MAC CE中添加该信息。
需要说明的是，该时间信息还可以携带在PDCP包头或者RLC包头中。
可选地，该第一数据包括一个或多个时间信息，以及对应的一个或多个业务数据。
具体地，该第一数据可以包括多种类型的业务数据，每种类型的业务数据对应一个时间信息。例如，如图3所示，包括时间信息的MAC CE与MAC SDU具有按照顺序一一映射的关系，即MAC CE1对应于MAC SDU1，MAC CE2对应于MAC SDU2，MAC CE3对应于MAC SDU3。其中，MAC CE可以通过SFN标识，MAC SDU可以通过逻辑信道号标识，也就是说，SFN标识和逻辑信道号标识具有映射关系。
可选地，该第一数据中的多个时间信息可以携带在对应的多个MAC CE中，该多个MAC CE可以携带在同一个MAC帧头之后，也可以各自携带在一个MAC帧头之后。
例如，如图4示出了一个MAC子头，多个MAC CE可以携带在同一个MAC头之后，其中R标识预留比特，F2表示后面数据域大小，如果后面数据大于32767字节且不是最后一个子头则该值为1，否则为0，E表示该子头后否还有MAC子头，若为1则有，若为0则后面字节是MACSDU或者MAC CE或者填充比特。例如，如图5所示。SFN1，SFN2，…，SFNn携带在一个MAC头之后。其中SFN1表示对应第一个MACSDU的SFN号，SFN2表示对应第二个MACSDU的SFN号，以此类推，SFNn表示对应第n个MAC SDU的SFN号。即上述每个SFN号都对应一个MAC SDU，此外也可以每个SFN号对应具有相同逻辑信道号标识的MAC SDU。或者该多个MAC CE中的每个MAC CE分别携带在一个MAC头之后，例如，如图6示出了其中某一个MAC CE携带在一个MAC头之后。每个MAC CE取值的对应的MAC SDU方式与上述相同。
因此，本申请实施例的中继通信的方法，作为父节点的第二节点可以向作为子节点的第一节点发送该第一配置信息。这样父节点向子节点分配用于建立承载的配置信息，即分 布式配置承载，不需要统一通过接入网设备配置，避免上级节点保存每个下级节点的每个承载的上下文，从而节省了信令开销。
