Description

一种资源分配的方法及装置
本申请要求于2017年09月01日提交中国专利局、申请号为201710780988.1、申请名称为“一种资源分配的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种资源分配的方法及装置。
背景技术
随着通信技术的发展，长期演进(Long Term Evolution，LTE)R10中引入了中继(Relay)技术，如图1所示，中继节点(Relay Node，RN)通过回传链路与宿主基站(Donor eNB，DeNB)通信，通过接入链路与用户设备(User Equipment，UE)进行通信。其中，UE可以将中继小区作为一个可接入的独立小区，RN可以直接调度中继小区中的UE，处于DeNB覆盖范围的UE也可以直接接入宿主小区。
在带内工作模式下，接入链路和回传链路使用相同频率的资源，为了避免接入链路和回传链路之间的干扰，会为接入链路和回传链路分配不同的子帧资源用于各自的数据传输，其中，为接入链路分配的子帧为接入子帧，为回传链路分配的子帧为中继子帧。RN服务的UE可以使用接入子帧进行数据传输，DeNB所服务的UE一般也采用接入子帧进行数据传输，当中继子帧存在剩余时，DeNB也可以调度UE使用中继子帧进行数据传输。
然而R10 Relay只支持简单的单跳RN的部署场景，无法满足未来网络更加多样化的需求，例如更加机动的部署、更大的覆盖以及更加灵活的资源分配方式等，所以为了满足日益增长的通信需求，需要部署多跳RN。然而目前为RN的接入链路和回传链路分配资源的方法仅并不能直接拓展到多跳RN场景。若在多跳场景中考虑直接复用现有R10 RN系统资源分配方法可以为所有RN分配一样的接入链路资源和回传链路资源，则非第一跳RN接入其它RN时，被接入的RN也工作于回传链路，导致非第一跳RN的中继子帧与其接入的RN的中继子帧冲突，被接入的RN无法为该非第一跳RN提供服务。因此，如何在多跳RN的部署场景下为RN分配资源是一个亟需解决的技术问题。
发明内容
本申请实施例提供一种资源分配的方法及装置，能够解决现有技术中无法在多跳RN的部署场景下为RN分配资源的问题。

在一种可能的设计中，所述第一无线接入网节点根据所述分组属性信息，自身的第二链路所使用的传输资源以及所述资源配置全局信息中的至少一种信息生成下一跳无线接入网节点的资源配置局部信息，所述下一跳无线接入网节点的资源配置局部信息包括所述下一跳无线接入网节点的第一链路所使用的传输资源信息和第二链路所使 用的传输资源信息；然后所述第一无线接入网节点向所述下一跳无线接入网节点发送所述下一跳无线接入网节点的资源配置局部信息。
其中，第一无线接入网节点为已经接入网络但还未被分配传输资源的RN，第一链路为接入链路，第二链路为回传链路。
采用该方法，第一无线接入网节点可以为下一跳无线接入网节点生成资源配置局部信息，由于资源配置全局信息中各跳第一类无线接入网节点的第二链路所使用的传输资源不同，所以第一无线接入网节点会根据资源配置全局信息，为下一跳无线接入网节点配置与第一无线接入网节点不同的第二链路所使用的传输资源信息，所以不会出现相邻跳无线接入网节点使用相同回传链路资源的情况，进而可避免相邻跳无线接入网节点使用相同的第二链路所使用的传输资源导致的干扰，且不需要为第一无线接入网节点配置多跳射频收发装置和复杂的设备内干扰处理单元，节约了成本。
在一种可能的设计中，所述第一无线接入网节点接收来自第二类无线接入网节点中的第二无线接入网节点的所述资源配置信息，所述资源配置信息包括所述资源配置全局信息；所述第一类无线接入网节点接收来自所述第二无线接入网节点的所述分组属性信息；然后，所述第一无线接入网节点根据所述分组属性信息确定所述第一无线接入网节点的第二链路所使用的传输资源分组；进而所述第一无线接入网节点确定所述资源配置全局信息中，所述第二链路所使用的传输资源分组对应的一组资源信息表示的资源为自身的第二链路所使用的传输资源。
其中，第一无线接入网节点为已经接入网络但还未被分配传输资源的RN，第二类无线接入网节点为宿主基站，第二无线接入网节点为第一无线接入网节点接入的宿主基站，第一链路为接入链路，第二链路为回传链路。
在一种可能的设计中，所述第一无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界对齐，所述第一无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界对齐。
第二方面，本申请的实施例提供一种资源分配的方法，该方法包括：

其中，第一类无线接入网节点为RN，第一无线接入网节点为已经接入网络但还未被分配传输资源的RN，第二类无线接入网节点为宿主基站，第二无线接入网节点为第一无线接入网节点接入的宿主基站，第二链路为回传链路。
采用该方法，第一无线接入网节点可根据接收到的资源配置信息来确定自身的第二链路所使用的传输资源，由于资源配置信息中的一组资源信息表示的资源为第一无线接入网节点的第二链路所使用的传输资源，另一组资源信息表示的资源为接入第一无线接入网节点的下一跳无线接入网节点的第二链路所使用的传输资源，所以相邻跳 无线接入网节点的第二链路所使用的传输资源不同，不会出现第一无线接入网节点与上一跳无线接入网节点使用相同的回传链路资源的情况，可以避免出现由于第一无线接入网节点与其接入的上一跳无线接入网节点的回传链路使用相同的传输资源，而导致的上一跳无线接入网节点无法为第一无线接入网节点提供数据回传服务的问题。
在一种可能的设计中，所述资源配置信息包括资源配置全局信息；所述资源配置全局信息包括以下信息中的任意一种或任意多种的组合：第二链路所使用的传输资源分组数，每个第二链路所使用的传输资源分组对应的所述至少两组资源信息中的一组资源信息，第二链路所使用的传输资源的分组模式，第二链路所使用的传输资源的分组模式的索引值，第一链路所使用的传输资源与各组第一类无线接入网节点的第二链路所使用的传输资源的配比方式，第一链路所使用的传输资源与各组第一类无线接入网节点的第二链路所使用的传输资源的配比方式的索引值，各组第二链路所使用的传输资源的配比方式和各组第二链路所使用的传输资源的配比方式的索引值。
其中，第一类无线接入网节点为RN，第一无线接入网节点为已经接入网络但还未被分配传输资源的RN，第二链路为回传链路。

在一种可能的设计中，所述资源配置全局信息中还包括第一链路所使用的传输资源的指示信息；所述第一链路所使用的传输资源的指示信息指示的所述第一无线接入网节点的第一链路所使用的传输资源与所述下一跳无线接入网节点的第二链路所使用的传输资源相同；或者，所述第一无线接入网节点的第一链路所使用的传输资源为所述下一跳无线接入网节点的第二链路所使用的传输资源的中的部分资源。
其中，第一无线接入网节点为已经接入网络但还未被分配传输资源的RN，第一链路为接入链路。
在一种可能的设计中，在所述第二类无线接入网节点中的第二无线接入网节点生成资源配置信息之前，所述第二无线接入网节点可以接收所述第一无线接入网节点或所述第一无线接入网节点接入的上一跳无线接入网节点，通过与所述第二无线接入网节点之间的各跳第一类无线接入网节点发送的标识信息；进而所述第二无线接入网节点根据所述标识信息确定所述第一无线接入网节点的分组属性信息，所述分组属性信息包括以下信息中的任意一种或任意多种的组合：所述第一无线接入网节点的分组索引，所述第一无线接入网节点的跳数和所述第一无线接入网节点的跳数的奇偶性。
其中，第二无线接入网节点为第一无线接入网节点接入的宿主基站。
在一种可能的设计中，所述资源配置信息包括资源配置局部信息；所述第二无线接入网节点根据所述分组属性信息确定所述第一无线接入网节点的第二链路所使用的传输资源分组；然后所述第二无线接入网节点确定所述资源配置全局信息中，所述第二链路所使用的传输资源分组对应的一组资源信息表示的资源为所述第一无线接入网 节点的第二链路所使用的传输资源；然后所述第二无线接入网节点确定所述资源配置全局信息中，所述第一链路所使用的传输资源信息表示的资源为所述第一无线接入网节点的第一链路所使用的传输资源信息；然后所述第二无线接入网节点确定所述第一无线接入网节点的第一链路所使用的传输资源信息和第二链路所使用的传输资源信息为所述资源配置局部信息。
其中，第一无线接入网节点为已经接入网络但还未被分配资源的RN，第二无线接入网节点为第一无线接入网节点接入的宿主基站，第一链路为接入链路，第二链路为回传链路。
采用该方法，第二无线接入网节点可以在第一无线接入网接入的过程中获取第一无线接入网节点的跳数信息，根据跳数信息确定分组属性信息，进而根据分组属性信息和资源配置全局信息生成第一无线接入网节点的资源配置局部信息，进而第一无线接入网节点可直接根据子帧配置局部信息确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源，由于第二无线接入网节点基站会为相邻跳第一无线接入网节点分配不同的第二链路所使用的传输资源，使得相邻跳第一无线接入网节点使用不同的资源进行数据传输，可以避免RN之间的干扰，实现了在多跳RN部署场景下合理地为多跳RN分配资源。
在一种可能的设计中，所述第一无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界对齐，所述第一无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界对齐。
第三方面、本申请的实施例提供一种资源分配的方法，该方法包括：第一类无线接入网节点中的第一无线接入网节点接收来自第二类无线接入网节点中的第二无线接入网节点的所述第一无线接入网节点的资源配置局部信息，和接入所述第一无线接入网节点的下一跳无线接入网节点的资源配置局部信息。

然后，所述第一无线接入网节点将所述第一无线接入网节点的资源配置局部信息中的第一链路所使用的传输资源信息表示的资源作为自身的第一链路所使用的资源，将第二链路所使用的传输资源信息表示的资源作为自身的第二链路所使用的资源；所述第一无线接入网节点向所述下一跳无线接入网节点发送所述下一跳无线接入网节点的资源配置局部信息。

采用该方法，第一无线接入网节点可直接根据第二无线接入网节点发送的资源配置局部信息确定自身的第一链路可用的传输资源和第二链路可用的传输资源，由于第一无线接入网节点的资源配置信息中包括的第二链路所使用的传输资源信息表示的资源，与第一无线接入网节点的下一跳无线接入网节点的资源配置信息中包括的第二链路所使用的传输资源信息表示的资源不同，所以不会出现相邻跳第一类无线接入网节点使用相同的第二链路资源的情况，进而可以避免出现由于第一无线接入网节点与其接入的上一跳无线接入网节点的回传链路使用相同的传输资源，而导致的上一跳无线接入网节点无法为第一无线接入网节点提供数据回传服务的问题。
在一种可能的设计中，所述第一无线接入网节点的资源配置局部信息中包括的第一链路所使用的传输资源信息表示的资源，与所述下一跳无线接入网节点的资源配置局部信息中包括的第一链路所使用的传输资源信息表示的资源相同；或者，

在一种可能的设计中，所述第一无线接入网节点的资源配置局部信息中包括的第一链路所使用的传输资源信息表示的资源，与所述下一跳无线接入网节点的资源配置局部信息中包括的第一链路所使用的传输资源信息表示的资源相同；或者，

需要说明的是，本申请中“的(英文：of)”，相应的“(英文corresponding，relevant)”和“对应的(英文：corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
在详细描述本申请的技术方案之前，为了便于理解，先对本申请的实施例所应用的场景进行介绍。
本申请的实施例应用于如图2所示的通信系统中，该系统中包括宿主基站和RN以及UE。RN与UE之间的通信链路称为接入链路，RN与宿主基站之间的通信链路，以及各级RN之间的通信链路称为回传链路。
本申请提供的资源分配的方法可以应用于通信系统中，该通信系统中包括终端设备，作为宿主基站的无线接入网设备以及作为中继节点的无线接入网设备等。
其中，本申请所称无线接入网设备，在无线通信标准中也可以称为基站，在大部分场景中，是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置，本申请所称 的无线接入网设备包括但不限于：各种形式的宏基站，微基站(也称为小站)，中继站，发送接收点(Transmission Reception Point，TRP)，下一代网络节点(g Node B，gNB)、演进型节点B(evolved Node B，eNB)、连接下一代核心网的演进型节点B(ng evolved Node B，ng-eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved Node B，或Home Node B，HNB)、处理通信数据的基带单元(Base Band Unit，BBU)、以及未来演进网络或新型网络中的基站节点等，还可以包括无线局域网(wireless local area network，WLAN)接入设备等非第三代合作伙伴计划(Third Generation Partnership Project，3GPP)系统的无线接入网设备。在采用不同的无线接入技术的系统中，具备相类似无线通信功能的无线接入网设备的名称可能会有所不同。仅为描述方便，本申请实施例中，上述可以为终端设备提供无线通信功能的装置统称为无线接入网设备。
本申请所称终端设备，是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。该终端设备可以包括各种类型的手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、无线数据卡、虚拟现实(Virtual Reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、机器类型通信(machine type communication，MTC)的终端设备，工业控制(industrial control)中的终端设备、无人驾驶(self driving)中的终端设备、远程医疗(remote medical)中的终端设备、智能电网(smart grid)中的终端设备、运输安全(transportation safety)中的终端设备、智慧城市(smart city)中的终端设备、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)，以及可穿戴设备(如智能手表，智能手环，计步器等)等等。本申请所称的终端设备，还可以被设置成固定位置，具有和前述终端设备相类似无线通信功能的设备。在采用不同的无线接入技术的系统中，具备相类似无线通信功能的终端设备的名称可能会有所不同，仅为描述方便，本申请实施例中，上述具有无线收发通信功能的装置统称为终端设备。
如图2所示，图2为该通信系统的一种可能的结构示意图，该通信系统中包括宿主基站，RN以及终端设备。宿主基站为具有为RN提供数据传输等服务的能力的通信站点。RN与宿主基站之间的通信链路以及各级RN之间的通信链路称为回传链路，RN与终端设备之间的链路称为接入链路。
多个RN可以通过回传链路直接与同一个宿主基站相连，RN还可以通过级联的方式接入宿主基站。为了便于描述，将直接连接于宿主基站的RN称为第一跳RN，将通过第一跳RN接入宿主基站的RN称为第二跳RN，同样，将连接于第二跳RN的RN称为第三跳RN，依次还可以有第四跳，第五跳至第N跳RN。另外宿主基站和RN均可以与终端设备进行通信，RN可以为终端设备提供无线数据传输服务，RN可以通过接入链路与终端设备进行数据传输，并通过回传链路将数据传输至宿主基站。
需要说明的是，图2仅为本申请所应用的通信系统的结构示意图，在实际部署过程中，通信系统中的设备数量不限于图1所示的设备数量。
在现有技术中，LTE R10只支持单跳RN的部署场景，在单跳RN的场景下，可以为接 入链路分配接入子帧，为回传链路分配中继子帧，然而在多跳RN的场景下，如果多跳RN均使用相同的中继子帧，则对于一个中间跳的RN(即后续多跳RN需要通过该中间跳RN接入宿主基站)，既需要在中继子帧保持自己的回传链路，又需要在中继子帧与后续多跳RN传输数据，对该中间跳RN的硬件能力提出很高的要求，同时增加了RN的处理复杂度和硬件成本，不是一个优选的解决方法。
所以为了实现多跳RN的部署，增加资源的复用效率，避免多个RN之间的中继子帧冲突，本申请的原理为：将无线传输资源分为回传链路资源和接入链路资源两组，各个RN以及宿主基站使用相同的接入链路进行数据传输，然后将回传链路资源分为多组，相邻跳的RN可以使用不同组的回传链路资源进行数据传输。
示例性的，如图3所示，RN1、RN2、RN3、RN4分别为第一跳至第四跳RN，其中，RN1直接与宿主基站相连，RN2与RN1相连，RN3与RN2相连，RN4与RN3相连，各RN下均有终端设备接入。宿主基站可以采用时分复用的方式为各RN分配资源，例如，R1为接入链路资源，R2和R3为中继链路资源，则各RN均使用R1与终端设备进行数据传输，奇数跳RN使用R2进行数据回传，偶数跳RN使用R3进行数据回传。通过这种资源分配方式，即可实现多跳RN的部署，且由于相邻跳RN使用的是不同的无线传输资源，就避免了RN之间的干扰，并且不需要RN具备多跳射频收发装置和复杂的设备内干扰处理单元。
在本申请的实施例中，图2和图3中的RN的结构如图4所示，RN可以包括存储器401，处理器402，通信接口403以及总线404，总线404用于实现这些装置之间的连接和相互通信。
其中，通信接口403，可以由天线来实现，可用于与外部网元之间进行数据交互，如：RN的通信接口403可收发与终端设备、其他RN以及宿主基站间的数据包或其他信息。
处理器402，可能是中央处理器(英文：Central Processing Unit，CPU)，也可以是特定集成电路(英文：Application Specific Integrated Circuit，ASIC)，或者是被配置成实施本发明实施例的一个或多个集成电路。例如：一个或多个微处理器(英文：Digital Signal Processor，DSP)，或，一个或者多个现场可编程门阵列(英文：Field Programmable Gate Array，FPGA)。处理器402具有处理管理功能，具体的，RN中的处理器402可以对接收到的终端设备、RN或宿主基站发送的数据或信息进行处理，或者对其他设备发送的信息或数据进行处理。

以下将结合图2至图4所示的通信系统以及宿主基站对本申请提供的资源分配的方法进行具体阐述。
首先，对本申请的实施例涉及到的术语进行简单介绍，以方便理解。
(1)、第一类无线接入网节点、第二类无线接入网节点
第一类无线接入网节点是指RN，第一无线接入网节点是指已经接入网络但还未被分配无线传输资源的RN，例如可以为接入通信系统中的某一跳RN，或者为接入宿主基站的RN。
第二类无线接入网节点为宿主基站，第二无线接入网节点为第一无线接入网节点接入的宿主基站。
(2)、第一链路所使用的传输资源、第二链路所使用的传输资源
第一链路所使用的传输资源为宿主基站或RN可用于在接入链路上进行数据传输的无线传输资源的集合，宿主基站或RN可以调度该集合中的全部资源或者部分资源用于与UE之间的数据传输。第一链路所使用的传输资源信息为用于指示或推演第一链路所使用的传输资源的信息。第一链路具体可以为接入链路，相应地，第一链路所使用的传输资源可以为接入链路资源。
第二链路所使用的传输资源为RN可用于在回传链路上进行数据传输的无线传输资源的集合，被该RN接入的通信站点可调度该集合中的全部资源或部分资源用于与该RN之间的数据传输。第二链路所使用的传输资源信息为用于指示或推演第二链路所使用的传输资源的信息。第二链路具体可以为回传链路，相应地，第二链路所使用的传输资源可以为回传链路资源。
接入链路资源和回传链路资源的分配可以包括以下两种情况：
情况1：第一链路与第二链路的空口不同，宿主基站以及各跳RN的第一链路所使用的传输资源相同，相邻跳RN的第二链路所使用的传输资源不同。
示例性地，如图6所示，RN4通过Un4口与RN3通信，RN3通过Un3口与RN2通信，RN2通过Un2口与RN1通信，RN1通过Un1口与宿主基站通信。其中，Un4、Un3、Un2、Un1采用相同的空口机制，但是使用资源可能相同或不同。UE4、UE3、UE2、UE1、UE0分别通过Uu口与RN4、RN3、RN2、RN1、宿主基站通信。其中，Uu口与Un4、Un3、Un2、Un1采用不同的空口机制，并且使用不同的无线资源。
需要说明的是，本申请的实施例中的两条链路的空口机制相同可以指两条链路收发数据使用的物理层技术相同或大部分相同，物理层以上的协议栈功能和处理流程可以不同。
如图6所示，以FDD系统为例，载波1用作下行传输，假设一个资源周期为子帧[x+1，y]，其中，在下行载波1中，[x+1,m]为资源分组R1，[m+1,n]为资源分组R2，[n+1,y]为资源分组R3。载波2用作上行传输，可选地，其资源分组与下行载波的资源分组有对应关系，例如上行载波资源分组与对应地下行载波资源分组相差的子帧数为k，即在上行载波2中，[x+1+k,m+k]为资源分组R1，[m+1+k,n+k]为资源分组R2，[n+1+k,y+k]为资源分组R3。k的取值可以为协议规定或者由宿主基站配置。示例性的，可以将下行载波1和上行载波2中的R1作为接入链路资源，R2作为偶数组RN的回传链路资源，R3作为奇数组RN的回传链路资源。
进一步可选的，第一无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界对齐，第一无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界对齐。
示例性地，令下行载波1中R2的边界与上行载波2中R1的边界对齐，从而RN2可以同时接收UE2使用上行载波1中的R1在Uu口发来的数据和RN1使用下行载波2中的R2在Un2口发来的数据，其它偶数跳RN的处理与RN2类似，使得RN2可以仅使用一套接收设备，同时接收Uu口和Un2口的数据，节省了设备的硬件成本。同理，令下行载波1中R3的边界与上行载波2中R2的边界对齐，从而RN1可以同时接收RN2使用上行载波2中的R2在Un2口发来的数据和宿主基站使用下行载波1中的R3在Un1口发来的数据，其它奇数跳RN的处理与RN1类似。
需要说明的是，若子帧[x+1，y]为第一个资源周期，则在第二个资源周期中，下行载波1中R1的边界与第一个资源周期中上行载波2中R3的边界也是对齐的。可选的，该子帧对齐的方式可以通过令R1子帧数、R2子帧数、R3子帧数和k值四者相同来实现。需要说明的是，该方式仅为一种示例，不排除其它资源分配方式，令RN节点可以同时接收至少两条链路的数据，和/或同时发送至少两条链路的数据。
情况2：第一链路与第二链路的空口相同。相邻跳第一无线接入网节点的第二链路所使用的传输资源不同。第一无线接入网节点的第一链路所使用的传输资源可以和下一跳第一类无线接入网节点的第二链路所使用的传输资源相同，或者，第一无线接入网节点的第一链路所使用的传输资源为下一跳第一类无线接入网节点的第二链路所使用的传输资源中的一部分资源。
其中，第一无线接入网节点的第一链路所使用的传输资源和下一跳第一类无线接入网 节点的第二链路所使用的传输资源可以为同一个资源集合中的资源，第一无线接入网节点可以通过为下一跳第一类无线接入网节点和终端设备调度该资源集合中的资源，来避免下一跳第一类无线接入网节点和终端设备同时使用相同的资源。例如，在同一时间段，第一无线接入网节点的第一链路所使用的传输资源为该资源集合中的一部分资源，下一跳第一类无线接入网节点的第二链路所使用的传输资源为该资源集合中的另一部分资源。或者，在一个时间段内，第一无线接入网节点的第一链路所使用的传输资源为该资源集合中的全部资源，在另一个时间段内，下一跳第一类无线接入网节点的第二链路所使用的传输资源为该资源集合中的全部资源。
在通信系统中存在多跳第一类无线接入网节点的情况下，第一类无线接入网节点中的第一无线接入网节点既需要通过下一跳第一类无线接入网节点的第二链路接收数据，又需要通过自身的第二链路向上一跳第一类无线接入网节点发送数据，为相邻跳第一类无线接入网节点分配不同的第二链路所使用的传输资源，可以避免第一无线接入网节点在自身的第二链路上发送的数据，对通过下一跳无线接入网节点的第二链路接收的数据产生干扰。
示例性地，如图7所示，RN4通过Un4口与RN3通信，RN3通过Un3口与RN2通信，RN2通过Un2口与RN1通信，RN1通过Un1口与宿主基站通信。UE3通过Uu4口与RN3通信，UE2通过Uu3口与RN2通信，UE1通过Uu2口与RN1通信，UE0通过Uu1口与宿主基站通信。其中，Un4、Un3、Un2、Un1、Uu4、Uu3、Uu2以及Uu1采用相同的空口机制，但是使用资源可能相同或不同。
如图7所示，以FDD系统为例，载波1用作下行传输，一个资源周期为子帧[x+1，y]，其中[x+1,m]为资源分组R1，[m+1,y]为资源分组R2。载波2用作上行传输，可选地，其资源分组与下行载波的资源分组有对应关系，例如相差子帧数为k，即[x+1+k,m+k]为资源分组R1，[m+1+k,y+k]为资源分组R2。k的取值可以为协议规定或者由宿主基站配置。示例性的，可以将R1作为奇数组RN的回传链路资源，R2作为偶数组RN的回传链路资源。可选的，每一跳RN服务的UE使用的接入链路资源可以与接入该RN的下一跳RN的回传链路资源相同，或者为所述回传链路资源的一部分。
可选的，第一无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界对齐，第一无线接入网节点的第二链路所使用的传输资源中的下行子帧的边界与相邻跳第一类无线接入网节点的第二链路所使用的传输资源中的上行子帧的边界对齐。
示例性地，令下行载波1中R2的边界与上行载波2中R1的边界对齐，下行载波1中R1的边界与上行载波2中R2的边界对齐，从而RN2可以同时接收RN3使用上行载波2中的R1在Un3发来的数据(若Uu3也复用R1，则此时也可能是UE2使用上行载波2中的R1在Uu3发来的数据)和RN1使用下行载波1中的R2在Un2口发来的数据，另外，RN1可以使用下行载波1中的R2在Un2发送数据给RN2(若Uu2也复用R2，则此时也可能是使用下行载波1中的R2在Uu2发送数据给UE1)，同时RN1使用上行载波2中的R1在Un1口发送数据给宿主基站。使得RN2可以仅使用一套接收设备，同时接收Un3(或Uu3)口和Un2口的数据，RN1可以仅使用一套发送设备，同时发送Un1口和Un2(或Uu2)口的数据，节省了设备的硬件成本。其它偶数跳RN的接收处理与RN2类似，其它奇数跳RN的发送处理与RN1类似。
同理，若子帧[x+1，y]为第一个资源周期，则在第二个资源周期中下行载波1中R1的边界与第一个资源周期中上行载波2中R2的边界对齐，从而RN1可以同时接收RN2在Un2口发来的数据(若Uu2也复用R2，则此时也可能是UE1使用上行载波2中的R2在Uu2发来的数据)和宿主基站使用第二个资源周期中的下行载波1中的R1在Un1口发来的数据，另外，RN2可以使用第二个资源周期中下行载波1中的R1在Un3发送数据给RN3(若Uu3也复用R1，则此时也可能是RN2使用第二个资源周期中下行载波1中的R1在Uu3发送数据给UE2)，同时RN2使用上行载波2中的R2在Un2口发送数据给RN1。其它奇数跳RN的接收处理与RN1类似，其他偶数跳的发送处理与RN2类似。可选的，该子帧对齐的方式可以通过令R1子帧数、R2子帧数、和k值四者相同。需要说明的是，该方式仅为一种示例，不排除其它资源分配方式，令RN节点可以同时接收至少两条链路的数据，和/或同时发送至少两条链路的数据。
可选地，宿主基站的接入链路与接入宿主基站的第一跳RN使用的回传链路可以使用相同的资源集合。RN的接入链路与接入该RN的下一跳RN使用的接入链路可以使用相同的资源集合。隔跳RN使用不同的接入链路资源集合。
示例性地，无线传输资源可以具体对应时域资源、频域资源、空域资源等形式。例如，对于FDD系统，无线传输资源可以为某上/下行载波的子帧资源和/或波束；对于TDD系统，无线传输资源可以为时频资源块和/或波束。
(3)、其他术语
本文中的术语“多个”是指两个或两个以上。
本文中的术语“第一”、“第二”等仅是为了区分不同的对象，并不限定其先后顺序。例如，第一无线接入网节点和第二无线接入网节点仅仅是为了区分不同的无线接入网节点，并不限定其先后顺序。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系；在公式中，字符“/”，表示前后关联对象是一种“相除”的关系。
如图8所示，本申请的实施例提供了一种资源分配的方法，该方法应用于图2所示的通信系统中，该方法包括：
801、第一类无线接入网节点中的第一无线接入网节点接收资源配置信息。
该步骤具体可以实现为步骤801a或步骤801b。
801a、第一无线接入网节点接收来自第二类无线接入网节点中的第二无线接入网节点的资源配置信息。可选的，上一跳无线接入网节点接收来自第二无线接入网节点的资源配置信息后，将该资源配置信息发送给第一无线接入网节点。
801b、第一无线接入网节点接收来自第一无线接入网节点接入的上一跳无线接入网节点的资源配置信息。
其中，第一类无线接入网节点可以为RN，第一类无线接入网节点中的第一无线接入网节点是指等待被分配无线传输资源的RN。上一跳无线接入网节点为等待被分配无线传输资源的RN接入的RN。示例性地，第一类无线接入网节点可以为图2中的第三跳RN，上一跳无线接入网节点为图2中第三跳RN接入的第二跳RN。第二类无线接入网节点中的第二无 线接入网节点是指第一无线接入网节点接入的宿主基站。示例性地，第二无线接入网节点可以为图2中的宿主基站。
资源配置信息包括至少两组资源信息，其中一组资源信息表示的资源为第一无线接入网节点的第二链路所使用的传输资源，另一组资源信息表示的资源为接入第一无线接入网节点的下一跳无线接入网节点的第二链路所使用的传输资源。
其中，第一链路为第一无线接入网节点的接入链路，接入链路是第一无线接入网节点与终端设备之间的通信链路，示例性地，接入链路为图2中第三跳RN与接入第三跳RN的终端设备之间的通信链路。
第二链路为第一无线接入网节点的回传链路，若第一无线接入网节点是第一跳第一类无线接入网节点，则回传链路为第一无线接入网节点与第二无线接入网节点之间的通信链路，例如，回传链路为图2中第一跳RN与宿主基站之间的通信链路。若第一无线接入网节点不是第一跳第一类无线接入网节点，则回传链路为第一无线接入网节点与第一无线接入网节点接入的上一跳无线接入网节点之间的通信链路，示例性的，回传链路为图2中的第三跳RN与第二跳RN之间的通信链路。
示例性地，第一链路所使用的传输资源为RN的接入链路所使用的资源，第二链路所使用的传输资源为RN的回传链路所使用的资源。
需要说明的是，上一跳无线接入网节点或第二无线接入网节点可发送一个广播消息或向第一无线接入网节点发送一个专用信令，专用信令可以为无线资源控制(Radio Resource Control，RRC)消息，该广播消息或专用信令中包括资源配置信息。
802、第一无线接入网节点将资源配置信息中的其中一组资源信息表示的资源作为自身的第二链路所使用的传输资源。
示例性地，若资源配置信息中包括两组资源信息，其中一组资源信息表示的资源为奇数跳第一类无线接入网节点的第二链路所使用的传输资源，另一组资源信息表示的资源为偶数跳第一类无线接入网节点的第二链路所使用的传输资源，则第一无线接入网节点的第二链路可使用其中一组资源信息表示的资源，下一跳无线接入网节点使用另一组资源信息表示的资源，相邻跳RN使用的传输资源不同。
采用该实施例提供的资源分配的方法，第一无线接入网节点可根据接收到的资源配置信息来确定自身的第二链路所使用的传输资源，由于资源配置信息中的一组资源信息表示的资源为第一无线接入网节点的第二链路所使用的传输资源，另一组资源信息表示的资源为接入第一无线接入网节点的下一跳无线接入网节点的第二链路所使用的传输资源，所以相邻跳无线接入网节点的第二链路所使用的传输资源不同，不会出现第一无线接入网节点与上一跳无线接入网节点使用相同的回传链路资源的情况，可以避免出现由于第一无线接入网节点与其接入的上一跳无线接入网节点的回传链路使用相同的传输资源，而导致的上一跳无线接入网节点无法为第一无线接入网节点提供数据回传服务的问题。
以下对上述实施例中的资源配置信息进行介绍。
资源配置信息包括以下信息中的任意一种或任意多种的组合：
信息A、资源配置全局信息；
信息B、所述第一无线接入网节点接入的上一跳无线接入网节点的第一链路所使用的传输资源信息；
信息C、所述上一跳无线接入网节点的第二链路所使用的传输资源信息。
关于信息A、
资源配置全局信息用于指示第二链路使用传输资源分配情况和各跳第一类无线接入网节点的第二链路使用传输资源的方式，具体可以包括以下信息中的任意一种或任意多种的组合：
每个第二链路所使用的传输资源分组对应的至少两组信息中的一组资源信息；

各组第二链路所使用的传输资源的配比方式；
各组第二链路所使用的传输资源的配比方式的索引值。
在一种实现方式中，资源配置全局信息中还包括第一链路所使用的传输资源信息，所述第一链路所使用的传输资源信息表示的资源为第一类无线接入网节点中的各跳无线接入网节点的第一链路所使用的传输资源。
其中，第一类无线接入网节点中的各跳无线接入网节点的第一链路使用相同的传输资源。
在另一种实现方式中，资源配置全局信息中还包括第一链路所使用的传输资源的指示信息，所述第一链路所使用的传输资源的指示信息用于指示所述第一无线接入网节点的第一链路所使用的传输资源，与所述下一跳无线接入网节点的第二链路所使用的传输资源相同；或者，所述第一无线接入网节点的第一链路所使用的传输资源为所述下一跳无线接入网节点的第二链路所使用的传输资源的子集。
其中，第一链路可以为接入链路，具体为第一类无线接入网节点与终端设备之间的通信链路，例如，可以为图2中第三跳RN与终端设备之间的通信链路。相应地，第一链路所使用的传输资源为接入链路使用的传输资源，第一链路所使用的传输资源信息可以为第一链路所使用的传输资源的编号等用于指示第一链路所使用的传输资源的信息。示例性地，若第一链路所使用的传输资源信息用于指示子帧资源，则第一链路所使用的传输资源信息可以包括子帧编号1至子帧编号x。
第二链路可以为回传链路，具体为第一无线接入网节点与上一跳无线接入网节点之间的通信链路，例如，可以为图2中第三跳RN与其接入的第二跳RN之间的通信链路。相应地，第二链路所使用的传输资源为回传链路所使用的传输资源。
第二链路所使用的传输资源的分组数为用于分配给第一类无线接入网节点的所有第二链路的传输资源被划分成的分组的数量，每个第二链路所使用的传输资源分组对应的无线传输资源信息可以为，每个第二链路所使用的传输资源分组对应的无线传输资源编号等用于指示每个第二链路所使用的传输资源分组包括的第二链路所使用的传输资源的信息。
示例性地，用于分配给第一类无线接入网节点的所有第二链路所使用的传输资源可以 被划分为两组，分别为偶数跳RN的第二链路所使用的传输资源和奇数跳RN的第二链路所使用的传输资源。或者，以第二链路所使用的传输资源为子帧资源为例，用于分配给第一类无线接入网节点的所有第二链路的传输资源为子帧x至子帧y，第二链路所使用的传输资源可以被分为3组，每个第二链路所使用的传输资源分组对应的无线传输资源信息如表1所示，分组1中包括子帧编号x+1至子帧编号m，分组2中包括子帧编号m+1至子帧编号n，分组3中包括子帧编号n+1至子帧编号y。
表1
分组1 子帧x+1至子帧m
分组2 子帧m+1至子帧n
分组3 子帧n+1至子帧y
需要说明的是，对应于第二链路所使用的传输资源的分组，也可以按照跳数对第一类无线接入网节点进行分组，例如，第1跳RN、第4跳RN、第7跳RN为分组1，第2跳RN、第5跳RN、第8跳RN为分组2，第3跳RN、第6跳RN、第9跳RN为分组3。RN跳数的分组与第二链路所使用的传输资源的分组一一对应。示例性的，可以指定RN的分组与第二链路所使用的传输资源的分组的映射关系，或者为第一无线接入网节点指定分组索引值。
第一链路所使用的传输资源与各组第一类无线接入网节点的第二链路所使用的传输资源的配比为，第一链路所使用的传输资源与各组第一类无线接入网节点的第二链路所使用的传输资源分别占总无线传输资源的比例。每种配比对应一种第一链路所使用的传输资源与第二链路所使用的传输资源的分配模式。其中，总无线传输资源包括第一链路所使用的传输资源和用于分配给第一类无线接入网节点的所有第二链路的传输资源。
可选地，第二无线接入网节点和第一类无线接入网节点中可存储第一链路所使用的传输资源与各组第一类无线接入网节点的第二链路所使用的传输资源的配比与分配模式的映射关系。
示例性地，第一链路所使用的传输资源与各组第一类无线接入网节点的第二链路所使用的传输资源的配比即为接入链路资源与各组RN的回传链路资源的配比，每种配比对应一种接入链路资源与回传链路资源的分配模式，作为一个例子，接入链路与奇数跳RN和偶数跳RN的回传链路资源的配比与分配模式之间的映射关系如表2所示。
表2
Figure PCTCN2018103665-appb-000001
与表2类似的，各组第一类无线接入网节点的第二链路所使用的传输资源的配比为， 各组第一类无线接入网节点的第二链路所使用的传输资源分别占总无线传输资源的比例。每种配比对应一种第二链路所使用的传输资源内部的分配模式。其中，总无线传输资源包括分配给各组第一类无线接入网节点的所有第二链路所使用的传输资源。
可选地，第二无线接入网节点和第一类无线接入网节点中可存储各组第二链路所使用的传输资源的配比与分配模式的映射关系。
示例性地，各组第一类无线接入网节点的第二链路所使用的传输资源的配比即为各组RN的回传链路资源的配比，每种配比对应一种回传链路资源的分配模式，作为一个例子，奇数跳RN和偶数跳RN的回传链路资源的配比与分配模式之间的映射关系如表3所示。
表3
Figure PCTCN2018103665-appb-000002
第一链路所使用的传输资源与第二链路所使用的传输资源的分配模式的索引值用于指示第一无线接入网节点的第一链路所使用的传输资源与回传链路资源的分配模式，示例性地，该分配模式的索引值可以为分配模式的编号，例如，分配模式的索引值为1，则代表第一无线接入网节点可根据表2中的分配模式1来确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源。类似的，第二链路所使用的传输资源的分配模式的索引值用于指示第一无线接入网节点的回传链路资源的分配模式，示例性地，该分配模式的索引值可以为分配模式的编号，例如，分配模式的索引值为1，则代表第一无线接入网节点可根据表3中的分配模式1来确定自身的第二链路所使用的传输资源。
可选地，如表1所示的分组信息和如表2、表3所示的分配模式信息可以通过显示的方式动态的告知第一无线接入网节点，例如在第一无线接入网节点接入网络的时候获取当前网络的资源配置信息；或者可以通过预先配置或者协议规定的方式告知第一接入网节点，例如第一无线接入网节点和第二无线接入网节点中可预先存储第二链路所使用的传输资源的分组信息和各分配模式对应的资源分配情况，第一无线接入网节点进一步获取分组索引值或分配模式索引值后，则可以确定自己可以使用的资源。
需要说明的是，表1、表2和表3所示的子帧资源划分方式仅为示例，本发明不限定子帧资源一定是连续的，例如接入链路资源、各组回传链路资源本身可以是不连续的，或者接入链路资源和各组回传链路资源的子帧可以是穿插分配的，或者各组回传链路资源的子帧是穿插分配的。另外，本发明中无线资源不限于表1、表2和表3中所示的子帧资源，本申请中的无线资源还可以为时间资源、频谱资源、时频资源、码资源、波束资源，以及上述资源中至少两种的组合。类似的，以上各种资源的分配也可以是不连续或穿插进行的。

其中，第一链路所使用的传输资源信息可以为第一链路所使用的传输资源的编号。
示例性地，若第一无线接入网节点为图2中的第三跳RN，则第一无线接入网节点接入的上一跳无线接入网节点为第三跳RN接入的第二跳RN，信息B为该第二跳RN的接入链路所使用的传输资源编号。
关于信息C、
所述上一跳无线接入网节点的第二链路所使用的传输资源信息。
其中，第二链路所使用的传输资源信息可以为第二链路所使用的传输资源的编号。
示例性地，若第一无线接入网节点为图2中的第三跳RN，则第一无线接入网节点接入的上一跳无线接入网节点为第三跳RN接入的第二跳RN，信息B为该第二跳RN的回传链路所使用的传输资源编号。
可选地，第一无线接入网节点还可以结合分组属性信息从资源配置信息中选择第二链路的传输资源信息，基于此，在本申请的实施例的另一种实现方式中，如图9所示，在上述步骤802、第一无线接入网节点将资源配置信息中的其中一组资源信息表示的资源作为自身的第二链路所使用的传输资源之前，还可以执行步骤901。
901、第一无线接入网节点接收分组属性信息。
分组属性信息用于指示第一无线接入网节点或第一无线接入网节点接入的上一跳无线接入网节点的传输资源信息，或其他用于推演第一无线接入网节点或第一无线接入网节点的传输资源信息。
其中，分组属性信息可以为分组索引信息或跳数相关信息，分组属性信息可以包括以下信息中的一种或多种的组合：

第一无线接入网节点接入的上一跳无线接入网节点的跳数；
第一无线接入网节点接入的上一跳无线接入网节点的跳数的奇偶性。
其中，分组索引可以为分组编号。
其中，步骤901具体可以实现为步骤901a或步骤901b。
901a、第一无线接入网节点接收来自第二无线接入网节点的分组属性信息。
901b、第一无线接入网节点接收来自上一跳无线接入网节点的分组属性信息。
需要说明的是，宿主基站可以将分组属性信息通过宿主基站与第一无线接入网之间的各跳无线接入网节点逐跳发送给第一无线接入网节点，即上一跳无线接入网节点接收到分组属性之后，可以将分组属性信息发送给第一无线接入网节点。
需要说明的是，上一跳无线接入网节点或第二无线接入网节点可发送一个广播消息或向第一无线接入网节点发送一个专用信令，专用信令可以为RRC，该广播消息或专用信令中包括分组属性信息。
可选地，在第一无线接入网节点接收到分组属性的信息的情况下，上述步骤802、第一无线接入网节点将资源配置信息中的其中一组资源信息表示的资源作为自身的第二链路所使用的传输资源，具体可以实现为步骤902至步骤903。
902、第一无线接入网节点根据分组属性信息确定第一无线接入网节点的第二链路所使用的传输资源分组。
903、第一无线接入网节点确定资源配置全局信息中，第二链路所使用的传输资源分组对应的一组资源信息表示的资源为自身的第二链路所使用的传输资源。
其中，资源配置全局信息中包括的具体信息不同，第一无线接入网节点确定自身的第二链路所使用的资源的方法也不同，具体的确定方法在下文中描述。
进一步可选地，由于资源配置全局信息中还包括第一链路所使用的传输资源信息，或者第一链路所使用的传输资源的指示信息，所以该方法进一步包括步骤904。
904、第一无线接入网节点根据资源配置全局信息确定自身的第一链路所使用的传输资源。
需要说明的是，上述步骤801和步骤901中的资源配置信息和分组属性信息可以被携带在同一个消息中，也可以通过两个消息发送资源配置信息和分组属性信息。
具体地，上一跳无线接入网节点或第二无线接入网节点可向第一无线接入网节点发送两次广播消息，或者发送两次专用信令，或者发送一次广播消息和一次专用信令。
示例性地，第一次发送的广播消息或专用信令中包括资源配置信息中的部分内容和分组属性信息，第二次发送的广播消息或专用信令中包括资源配置信息中的另一部分内容。
又例如，第一次发送的广播消息或专用信令中携带资源配置信息，第二次发送的广播消息或专用信令中携带分组属性信息；或者，第一次发送的广播消息或专用信令中携带资源配置全局信息，第二次发送的广播消息或专用信令中携带上一跳无线接入网节点的第一链路所使用的传输资源信息和第二链路所使用的传输资源信息。
资源配置信息和分组属性信息包含多种组合方式，资源配置信息和分组属性信息中包括的具体内容不同，图8和图9实施例中第一无线接入网节点确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源的方法也不同，示例性地，本申请的实施例可以提供以下六种实现方式：
方法一、第一无线接入网节点接收来自上一跳无线接入网节点的资源配置信息，资源配置信息为资源配置全局信息，第一无线接入网节点根据分组属性信息确定第一无线接入网节点的第二链路所使用的传输资源分组，第一无线接入网节点确定资源配置全局信息中，第二链路所使用的传输资源分组对应的一组资源信息表示的资源为自身的第二链路所使用的传输资源。
进一步地，若资源配置全局信息中包括第一链路所使用的传输资源信息，则第一无线接入网节点将第一链路所使用的传输资源信息表示的资源作为自身的第一链路所使用的传输资源信息。
若资源配置信息中包括第一链路所使用的传输资源的指示信息，则第一无线接入网节点可根据自身的分组属性信息确定下一跳无线接入网节点的分组属性信息，根据下一跳无线接入网节点的分组属性信息和资源配置全局信息，确定下一跳无线接入网节点的第二链路所使用的传输资源信息(或者第一无线接入网节点根据自身的第二链路所使用的资源信息和资源配置全局信息确定下一跳无线接入网节点的第二链路所使用的传输资源信息)，将下一跳无线接入网节点的第二链路所使用的传输资源信息表示的资源作为自身的第一链路所使用的传输资源。
需要说明的是，资源配置全局信息由第二无线接入网节点生成，并通过各跳第一类无线接入网节点逐跳转发给第一无线接入网节点，分组属性信息可以由第二无线接入网节点生成，并通过各跳第一类无线接入网节点逐跳转发给第一无线接入网节点，或者分组属性信息也可以由上一跳无线接入网节点生成，并发送给第一无线接入网节点。由于分组属性信息(例如跳数)占用的信令可以比较少，而且也可以应用于接入控制等流程，可以由上一跳无线接入网节点携带在其系统消息中通过广播方式告知第一无线接入网节点，而资源配置信息占用的信令一般较大，可以由第一类无线接入网节点或者由上一跳无线接入网节点通过专用信令告知第一无线接入网节点，从而第一无线接入网节点可以综合两部分信息获知自己的第一链路和第二链路所使用的传输资源。该方法的优点是比较灵活，同时可以节省广播信令开销。
示例性地，第二无线接入网节点为宿主基站，第一无线接入网节点为RN3，则宿主基站生成资源配置全局信息之后，将资源配置全局信息发送给RN1，RN1将资源配置全局信息发送给RN2，然后RN2将资源配置全局信息发送给RN3。
其中，若资源配置全局信息包括每个第二链路所使用的传输资源分组对应的所述至少两组资源信息中的一组资源信息，则第一无线接入网节点可根据分组属性信息确定自身的第二链路所使用的传输资源分组，进而可根据该第二链路所使用的传输资源分组从资源配置全局信息中查找该第二链路所使用的资源分组对应的一组资源信息，将查找到的一组资源信息表示的资源作为自身的第二链路所使用的传输资源，然后查找下一跳无线接入网节点的第二链路所使用的资源分组对应的一组资源信息，将第二链路所使用的资源分组对应的一组资源信息指示的部分或全部资源作为自身的第一链路所使用的传输资源。
若资源配置全局信息包括第一链路所使用的传输资源信息和每个第二链路所使用的传输资源分组对应的所述至少两组资源信息中的一组资源信息，分组属性信息包括第一无线接入网节点的分组索引，则第一无线接入网节点可确定资源配置全局信息中的第一链路所使用的传输资源信息表示的资源为自身的第一链路所使用的传输资源，和根据第一无线接入网节点的分组索引确定自身的第二链路所使用的传输资源分组，进而可根据该第二链路所使用的传输资源分组从资源配置全局信息中查找该第二链路所使用的传输资源分组对应的一组资源信息，将查找到的第二链路所使用的传输资源信息所指示的第二链路所使用的传输资源作为自身的第二链路所使用的传输资源。
若分组属性信息包括第一无线接入网节点接入的上一跳无线接入网节点的分组索引，则第一无线接入网节点可根据上一跳无线接入网节点的分组索引确定自身的分组索引，然后根据自身的分组索引确定的第二链路所使用的传输资源。例如，如果总分组数为2，并且上一跳无线接入网节点的分组索引为2，则第一无线接入网节点的分组索引可为1。
示例性地，若第一无线接入网节点为第三跳RN(RN3)，资源配置全局信息包括的接入链路所使用的传输资源信息为子帧编号1至子帧编号x，每个回传链路所使用的传输资源分组对应的回传链路资源信息如表1所示，分组属性信息包括的第一无线接入网节点的分组索引为2，则RN3可确定自身的接入链路所使用的传输资源为子帧1至子帧x，回传链路所使用的传输资源为分组2指示的子帧m+1至子帧n。
或者，若分组属性信息包括第一无线接入网节点的跳数或第一无线网接入节点的跳数的奇偶性，则第一无线接入网节点可根据第一无线接入网节点的跳数或跳数的奇偶性确定 自身的第二链路所使用的传输资源分组，进而可根据该第二链路所使用的传输资源分组从资源配置全局信息中查找该第二链路所使用的传输资源分组对应的一组资源信息，将查找到的第二链路所使用的传输资源分组对应的一组资源信息所指示的资源作为自身的第二链路所使用的传输资源。
若分组属性信息包括第一无线接入网节点接入的上一跳无线接入网节点的跳数或跳数的奇偶性，则第一无线接入网节点可根据上一跳无线接入网节点的跳数或跳数的奇偶性确定自身的跳数或跳数的奇偶性，进而根据自身的跳数或跳数的奇偶性来确定自身的第二链路所使用的传输资源。例如，如果上一跳无线接入网节点的跳数为2，则第一无线接入网节点的跳数为3，若上一跳无线接入网节点的跳数为偶数，则第一无线接入网节点的跳数为奇数。
可选地，资源配置全局信息中可以包括第一类无线接入网节点的分组策略，或者，各跳第一类无线接入网节点中均存储了第一类无线接入网节点的分组策略。例如，第1跳RN、第4跳RN、第5跳RN为分组1，第2跳RN、第5跳RN、第8跳RN为分组2，第3跳RN、第6跳RN、第9跳RN为分组3。由于第一类无线接入网节点的分组和第二链路所使用的传输资源的分组一一对应，所以在第一无线接入网节点根据分组策略以及自身的跳数信息确定自身的分组之后，就可以将该分组对应的第二链路所使用的传输资源信息所指示的第二链路所使用的传输资源作为自身的第二链路所使用的传输资源。
示例性地，若第一无线接入网节点为RN3，分组属性信息包括的RN3的跳数为3，或者RN的跳数为奇数跳，如果资源配置全局信息中包括偶数跳RN的回传链路所使用的传输资源信息和奇数跳RN的回传链路所使用的资源信息，则RN3可根据自身的跳数“3”确定自身为奇数跳，或直接根据通过分组属性信息中包括的RN跳数的奇偶性确定自身为奇数跳，进而确定奇数跳RN的回传链路所使用的传输资源信息指示的回传链路所使用的传输资源为自身的回传链路所使用的传输资源。
若第一无线接入网节点为RN3，分组属性信息包括的RN3的跳数为3，如果资源配置全局信息中包括如表1所示的每个回传链路所使用的传输资源分组对应的回传链路资源信息，结合上述对分组策略的举例，RN3可根据分组策略确定第3跳RN属于分组3，进而根据表1确定分组3对应的子帧n+1至子帧y为自身的回传链路所使用的传输资源。
方法二、对应于图6所示的资源分配方法，方法二的实现前提是资源配置全局信息中包括第一链路所使用的传输资源的信息，第一类无线接入网节点中的各跳无线接入网节点的第一链路所使用的传输资源相同。
该方法具体为：第一无线接入网节点接收来自上一跳无线接入网节点的资源配置信息，资源配置信息中包括资源配置全局信息，上一跳无线接入网节点的第一链路所使用的传输资源信息和上一跳无线接入网节点的第二链路所使用的传输资源信息。
所述第一无线接入网节点确定所述资源配置全局信息中，除所述上一跳无线接入网节点的第二链路所使用的传输资源信息之外的一组资源信息表示的资源为自身的第二链路所使用的传输资源，确定所述上一跳无线接入网节点的第一链路所使用的传输资源信息表示的资源为自身的第一链路所使用的传输资源。
其中，资源配置全局信息中包括每个第二链路所使用的传输资源分组对应的至少两组资源信息中的一组资源信息，第一无线接入网节点可根据上一跳无线接入网节点的第二链 路所使用的传输资源信息推断出自身的第二链路所使用的传输资源信息。示例性地，每个第二链路所使用的传输资源分组对应的第二链路所使用的传输资源如表1所示，若上一跳无线接入网节点的第二链路所使用的传输资源信息为偶数跳分组对应的一组资源信息表示的资源，则第一无线接入网节点可确定自身的第二链路所使用的传输资源为偶数跳分组对应的一组资源信息表示的资源。
或者，资源配置全局信息中包括第一链路所使用的传输资源与各组第二链路所使用的传输资源的配比，第一无线接入网节点可根据上一跳无线接入网节点的第二链路信息推断出自身的第二链路所使用的传输资源信息。示例性地，第一链路所使用的传输资源与各组第二链路所使用的传输资源的配比如表2所示，若上一跳无线接入网节点的第二链路所使用的传输资源信息为子帧x+1至子帧m，则第一无线接入网节点可根据表2确定上一跳无线接入网节点使用的分配模式1中偶数跳RN对应的回传链路资源，进而第一无线接入网节点可确定分配模式1中奇数跳RN对应的回传链路资源为自身的回传链路资源，以及确定分配模式1中指定的接入链路资源为自身的接入链路资源。
或者，资源配置全局信息中包括各组第二链路所使用的传输资源的配比，第一无线接入网节点可根据上一跳无线接入网节点的第二链路信息推断出自身的第二链路所使用的传输资源信息。示例性地，各组第二链路所使用的传输资源的配比如表3所示，若上一跳无线接入网节点的第二链路所使用的传输资源信息为子帧1至子帧m，则第一无线接入网节点可根据表3确定上一跳无线接入网节点使用的分配模式1中偶数跳RN对应的回传链路资源，进而第一无线接入网节点可确定分配模式1中奇数跳RN对应的回传链路资源为自身的回传链路资源，以及确定自身的接入链路资源为偶数跳RN的回传链路对应的资源。
方法三、对应于图7所示的资源分配方法，方法三的实现前提为资源配置全局信息中包括第一链路所使用的传输资源的指示信息，所述第一链路所使用的传输资源的指示信息用于指示所述第一无线接入网节点的第一链路所使用的传输资源，与所述下一跳无线接入网节点的第二链路所使用的传输资源相同；或者，所述第一无线接入网节点的第一链路所使用的传输资源为所述下一跳无线接入网节点的第二链路所使用的传输资源的子集。
该方法具体为：所述第一无线接入网节点接收来自所述上一跳无线接入网节点的资源配置信息，所述资源配置信息中包括所述资源配置全局信息、所述上一跳无线接入网节点的第二链路所使用的传输资源信息、所述上一跳无线接入网节点的第一链路所使用的传输资源信息中的至少一种。
所述第一无线接入网节点确定所述资源配置全局信息中，除所述上一跳无线接入网节点的第二链路所使用的传输资源信息之外的一组资源信息表示的资源为自身的第二链路所使用的传输资源；或者，所述第一无线接入网节点确定所述上一跳无线接入网节点的第一链路所使用的传输资源信息表示的全部资源或部分资源为自身的第二链路所使用的传输资源；所述第一无线接入网节点根据自身的第二链路所使用的传输资源信息和所述资源配置全局信息确定自身的第一链路所使用的传输资源。
可选地，若资源配置信息中包括资源配置全局信息和上一跳无线接入网节点的第二链路所使用的传输资源信息，则第一无线接入网节点根据上一跳无线接入网节点的第二链路所使用的传输资源信息和资源配置全局信息确定自身的第二链路所使用的传输资源，根据自身的第二链路所使用的传输资源信息和资源配置全局信息确定自身的第一链路所使用 的传输资源。
其中，第一无线接入网节点根据上一跳无线接入网节点的第二链路所使用的传输资源信息和资源配置全局信息确定自身的第二链路所使用的传输资源可参考方法二种的描述，此处不再赘述。
第一无线接入网节点确定自身的第二链路所使用的传输资源之后，可根据自身的第二链路所使用的传输资源信息和资源配置全局信息确定下一跳无线接入网节点的第二链路所使用的传输资源，进而确定下一跳无线接入网节点的第二链路所使用的传输资源中的全部或部分资源为自身的第一链路所使用的传输资源。
示例性地，结合图7，假设第一接入网节点为RN2，则可根据RN2的Un2所使用的传输资源和资源配置全局信息确定RN3的Un3所使用的传输资源，第一链路资源的指示信息指示了RN2的Uu3使用的传输资源与RN3的Un3所使用的传输资源相同，或者为RN3的Un3所使用的传输资源的一部分，进而RN2可确定自身的第一链路所使用的传输资源为RN3的Un3所使用的传输资源中的全部资源或部分资源。
可选地，若资源配置信息中包括资源配置全局信息和上一跳无线接入网节点的第一链路所使用的传输资源信息，则第一无线接入网节点确定上一跳无线接入网节点的第一链路所使用的传输资源信息指示的全部资源或部分资源为自身的第二链路所使用的传输资源，根据自身的第二链路所使用的传输资源信息和资源配置信息确定自身的第一链路所使用的传输资源。
其中，由于资源配置全局信息中包括了第一链路所使用的传输资源的指示信息，该指示信息指示了第一无线接入网节点的第一链路所使用的传输资源与下一跳无线接入网节点的第二链路所使用的传输资源相同，或者为所述下一跳无线接入网节点的第二链路所使用的传输资源中的部分资源。结合图7，若RN2为第一无线接入网节点，资源配置信息中包括RN1的Uu2使用的传输资源，则RN2可根据第一链路所使用的传输资源的指示信息确定RN1的Uu2使用的传输资源中的全部资源或部分资源为自身的第二链路所使用的传输资源。
第一无线接入网节点确定自身的第一链路所使用的传输资源之后，可根据自身的第二链路所使用的传输资源信息和资源配置全局信息确定下一跳无线接入网节点的第二链路所使用的传输资源，进而确定下一跳无线接入网节点的第二链路所使用的传输资源中的全部或部分资源为自身的第一链路所使用的传输资源。
可选地，若资源配置信息中包括资源配置全局信息、上一跳无线接入网节点的第一链路所使用的传输资源信息和上一跳无线接入网节点的第二链路所使用的传输资源信息，则第一无线接入网节点确定上一跳无线接入网节点的第一链路所使用的传输资源信息指示的全部资源或部分资源为自身的第二链路所使用的传输资源，或者根据上一跳无线接入网节点的第二链路所使用的传输资源信息和资源配置全局信息确定自身的第二链路所使用的传输资源。然后根据自身的第二链路所使用的传输资源信息和资源配置信息确定自身的第一链路所使用的传输资源。
可选地，若第二链路所使用的传输资源分组仅包括偶数跳第二链路所使用的传输资源分组和奇数跳第二链路所使用的传输资源分组，第一无线接入网节点接收到的资源配置信息中包括上一跳无线接入网节点的第一链路所使用的传输资源信息和第二链路所使用的 资源信息，第一接入网节点可确定上一跳无线接入网节点的第一链路所使用的传输资源为自身的第二链路所使用的传输资源，进而确定上一跳无线接入网节点使用的第二链路所使用的传输资源为自身的第一链路所使用的传输资源。
方法四、第一无线接入网节点接收来自上一跳无线接入网节点的资源配置信息，资源配置信息中可以包括资源配置全局信息和资源配置局部信息，或者资源配置信息中只包括资源配置局部信息。第一无线接入网节点将资源配置局部信息中的第二链路所使用的传输资源信息表示的资源作为自身的第二链路所使用的传输资源，将资源配置局部信息中的第一链路所使用的传输资源信息表示的资源作为自身的第一链路所使用的传输资源。
其中，资源配置局部信息为第一无线接入网节点的第一链路所使用的传输资源信息和第二链路所使用的传输资源信息，即上一跳无线接入网节点可直接告知第一无线接入网节点其第一链路所使用的传输资源信息和第二链路所使用的传输资源信息。
方法五、第一无线接入网节点接收来自第二类无线接入网节点中的第二无线接入网节点的资源配置信息，资源配置信息中包括资源配置全局信息和资源配置局部信息，或者资源配置信息中只包括资源配置局部信息。进而第一无线接入网节点将资源配置局部信息中的第一链路所使用的传输资源信息表示的资源为自身的第一链路所使用的传输资源，将资源配置局部信息中的第二链路所使用的传输资源信息表示的资源作为自身的第二链路所使用的传输资源。
方法六、第一无线接入网节点接收来自第二类无线接入网节点中的第二无线接入网节点的资源配置信息，资源配置信息包括资源配置全局信息；第一类无线接入网节点接收来自第二无线接入网节点的分组属性信息；第一无线接入网节点根据分组属性信息确定第一无线接入网节点的第二链路所使用的传输资源分组；第一无线接入网节点确定资源配置全局信息中，第二链路所使用的传输资源分组对应的一组资源信息表示的资源为自身的第二链路所使用的传输资源。
其中，方法六和方法一的区别为第一无线接入网节点获取的第一信息的来源不同，第一无线接入网确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源的方法与上述方法一相同，此处不再赘述。
可选地，在本申请的实施例的另一种实现方式中，在第一无线接入网节点根据资源配置信息和/或分组属性信息确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源之后，如图10所示，该方法还包括：
1001、第一无线接入网节点根据分组属性信息，自身的第一链路所使用的传输资源，自身的第二链路所使用的传输资源以及资源配置全局信息中的至少一种信息生成下一跳无线接入网节点的资源配置局部信息。
其中，所述下一跳无线接入网节点的资源配置局部信息包括所述下一跳无线接入网节点的第一链路所使用的传输资源信息和/或第二链路所使用的传输资源信息。
第一无线接入网节点在确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源之后，可根据分组属性信息，自身的第一链路所使用的传输资源和第二链路所使用的传输资源和资源配置全局信息中的至少一种信息推断出下一跳无线接入网节点的第一链路所使用的传输资源和第二链路所使用的传输资源。
示例性地，若第一无线接入网节点为RN3，则下一跳无线接入网节点为RN4。
情况1、由于各跳RN的接入链路所使用的传输资源相同，则RN3可将自身的接入链路所使用的传输资源确定为下一跳RN的接入链路所使用的传输资源，若RN3确定自身的回传链路所使用的传输资源为奇数跳RN分组对应的一组资源，则可确定下一跳RN的回传链路资源为偶数跳RN分组对应的一组资源，进而从资源配置全局信息中查找到偶数跳RN分组对应的一组资源信息，将偶数跳RN的回传链路所使用的传输资源信息作为下一跳无线接入网节点的回传链路所使用的传输资源信息。
情况2、若第二链路所使用的传输资源分组仅包括偶数跳第二链路所使用的传输资源分组和奇数跳第二链路所使用的传输资源分组，则第一无线接入网节点可根据自身的第一链路所使用的传输资源和第二链路所使用的传输资源生成下一跳无线接入网节点的资源配置局部信息。具体地，第一无线接入网节点可确定自身的回传链路所使用的传输资源为下一跳RN的接入链路所使用的传输资源，自身的接入链路所使用的传输资源为下一跳RN的回传链路所使用的传输资源。
或者，第一无线接入网节点根据自身的第一链路所使用的传输资源和资源配置全局信息生成下一跳无线接入网节点的资源配置局部信息。即第一无线接入网节点可确定自身的第一链路所使用的传输资源中的全部或部分资源为下一跳第一无线接入网节点的第二链路所使用的传输资源，进而第一无线接入网节点可根据下一跳无线接入网节点的第二链路所使用的传输资源和资源配置全局信息确定下一跳无线接入网节点的第一链路所使用的传输资源。
1002、第一无线接入网节点向下一跳无线接入网节点发送下一跳无线接入网节点的资源配置局部信息。
1003、下一跳无线接入网节点接收资源配置局部信息，根据资源配置局部信息确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源。
采用上述实施例的方法，第一无线接入网节点可以为下一跳无线接入网节点生成资源配置局部信息，由于资源配置全局信息中各跳第一类无线接入网节点的第二链路所使用的传输资源不同，所以第一无线接入网节点会根据资源配置全局信息，为下一跳无线接入网节点配置与第一无线接入网节点不同的第二链路所使用的传输资源信息，所以不会出现相邻跳无线接入网节点使用相同回传链路资源的情况，进而可避免相邻跳无线接入网节点使用相同的第二链路所使用的传输资源导致的干扰，且不需要为第一无线接入网节点配置多跳射频收发装置和复杂的设备内干扰处理单元，节约了成本。
可选地，在本申请的实施例的另一种实现方式中，对应于上述方法四，第二无线接入网节点可以在第一无线接入网节点接入时，获取第一无线接入网节点的分组属性信息，进而根据第一无线接入网节点的分组属性信息，为第一无线接入网节点生成资源配置局部信息，如图11所示，该方法包括：
1101、第一无线接入网节点与上一跳无线接入网节点建立通信连接。
1102、上一跳无线接入网节点通过与第二无线接入网节点之间的各跳第一类无线接入网节点，向第二无线接入网节点发送标识信息。
其中，标识信息包括第一无线接入网节点的ID，上一跳无线接入网节点的ID，以及转发过该标识信息的第一类无线接入网节点的ID。
示例性地，第一无线接入网节点为RN3，第二无线接入网节点为宿主基站，RN2向RN1 发送标识信息，标识信息中携带RN3的ID和RN2的ID，RN1接收到标识信息后，将RN1的ID添加至标识信息中，再向宿主基站发送标识信息，向宿主基站发送的标识信息中携带RN3的ID、RN2的ID和RN1的ID。
可选地，标识信息可以包括一个变量，每个转发该标识信息的第一类无线接入网节点都对该变量进行操作。示例性地，RN2向RN1发送的标识信息中携带变量“2”，每个转发该标识信息的RN都会对该变量进行加1操作，RN1接收到标识信息后，将标识信息中的变量“2”更新为变量“3”，然后将标识信息发送给宿主基站。再例如，RN2向RN1发送的标识信息中携带变量“0”，每个转发该标识信息的RN都会对该变量进行“0,1翻转”操作，即RN1接收到标识信息之后，会将标识信息中的变量“0”更新为变量“1”，并将携带变量“1”的标识信息发送给宿主基站。
可选地，还可以由第一无线接入网节点通过与第二无线接入网节点之间的各跳第一类无线接入网节点，向第二无线接入网节点发送标识信息。
1103、第二无线接入网节点接收第一类无线接入网节点的标识信息，根据第一类无线接入网节点的标识信息确定第一无线接入网节点的分组属性信息。
其中，所述分组属性信息包括以下信息中的任意一种或任意多种的组合：所述第一无线接入网节点的分组索引，所述第一无线接入网节点的跳数和所述第一无线接入网节点的跳数的奇偶性。
其中，第二无线接入网节点可根据标识信息确定第一无线接入网节点的跳数信息，进而根据第一无线接入网节点的跳数信息确定第一无线接入网节点的分组属性信息。
需要说明的是，第二无线接入网节点在接收标识信息前需先确定标识信息的类型，可选地，第二无线接入网节点可规定第一类无线接入网节点可发送的标识信息的类型，或者第二无线接入网节点可和第一类无线接入网节点协商标识信息的类型。
示例性地，若宿主基站规定第一类无线接入网节点可发送的标识信息的类型为RN的ID，则可确定标识信息中携带的RN的ID的数量为第一无线接入网节点的跳数，如果宿主基站接收到的标识信息中携带RN3的ID，RN2的ID以及RN1的ID，则宿主基站可确定第一无线接入网节点为第三跳RN。若宿主基站接收到的标识信息中携带变量“3”，则宿主基站可确定第一无线接入网节点为第三跳RN，或者，若宿主基站接收到的标识信息中携带变量“1”，则宿主基站可确定第一无线接入网节点为奇数跳RN。
1104、第二无线接入网节点根据分组属性信息和资源配置全局信息生成第一无线接入网节点的资源配置局部信息。
其中，第二无线接入网节点首先根据分组属性信息确定第一无线接入网节点的第二链路所使用的传输资源分组，然后第二无线接入网节点确定资源配置全局信息中，第二链路所使用的传输资源分组对应的一组资源信息表示的资源为第一无线接入网节点的第二链路所使用的传输资源，然后第二无线接入网节点确定资源配置全局信息中，第一链路所使用的传输资源信息表示的资源为第一无线接入网节点的第一链路所使用的传输资源信息，进而第二无线接入网节点确定第一无线接入网节点的第一链路所使用的传输资源信息和第二链路所使用的传输资源信息为资源配置局部信息。
例如，宿主基站根据分组属性信息确定第一无线接入网节点为奇数跳RN，则确定第一无线接入网节点的回传链路所使用的传输资源为奇数跳RN的回传链路所使用的传输资源 分组对应的一组资源，进而生成资源配置局部信息，资源配置局部信息中包括接入链路所使用的传输资源信息和奇数跳RN的回传链路所使用的传输资源分组对应的一组资源信息。
1105、第二无线接入网节点通过第二无线接入网节点与第一无线接入网节点之间的各跳第一类无线接入网节点向第一无线接入网节点发送资源配置局部信息。
其中，第二无线接入网节点可以在向第一无线接入网节点发送的RN重配置消息中携带资源配置局部信息，或者也可以向第一无线接入网节点发送专用信令，专用信令中携带资源配置局部信息。
示例性地，若第一无线接入网节点为RN3，则宿主基站可以将资源配置局部信息发送给RN1，再由RN1发给RN2，再由RN2将资源配置局部信息发送给RN3。
1106、第一无线接入网节点接收资源配置局部信息，确定资源配置局部信息中的第一链路所使用的传输资源信息指示的资源为自身的第一链路所使用的传输资源，确定资源配置局部信息中的第二链路所使用的传输资源信息指示的资源为自身的第二链路所使用的传输资源。
采用本申请的实施例提供的资源分配的方法，第二无线接入网节点可以在第一无线接入网接入的过程中获取第一无线接入网节点的跳数信息，根据跳数信息确定分组属性信息，进而根据分组属性信息和资源配置全局信息生成第一无线接入网节点的资源配置局部信息，进而第一无线接入网节点可直接根据子帧配置局部信息确定自身的第一链路所使用的传输资源和第二链路所使用的传输资源，由于第二无线接入网节点基站会为相邻跳第一无线接入网节点分配不同的第二链路所使用的传输资源，使得相邻跳第一无线接入网节点使用不同的资源进行数据传输，可以避免RN之间的干扰，实现了在多跳RN部署场景下合理地为多跳RN分配资源。
可选地，在另一种实施场景下，本申请的实施例还提供一种资源分配的方法，如图12所示，该方法包括：
1201、第二类无线接入网节点中的第二无线接入网节点向第一类无线接入网节点中的第一无线接入网节点发送第一无线接入网节点的资源配置局部信息，和接入所述第一无线接入网节点的下一跳无线接入网节点的资源配置局部信息。相应地，第一无线接入网节点接收来自第二无线接入网节点的第一无线接入网节点的资源配置局部信息，和接入所述第一无线接入网节点的下一跳无线接入网节点的资源配置局部信息。
其中，第一类无线接入网节点是指RN，第一无线接入网节点是指已经接入网络但还未被分配无线传输资源的RN，例如可以为接入通信系统中的某一跳RN，或者为接入宿主基站的RN。
第二类无线接入网节点为宿主基站，第二无线接入网节点为第一无线接入网节点接入的宿主基站。
