随着IAB技术的发展演进，IAB节点需要实现跨跳即across hop。为了便于说明，下面将跨跳称为跳。其中，IAB节点与该IAB节点的子IAB节点之间的跳即跳A由该IAB节点调度。IAB节点与该IAB节点的父IAB节点之间的跳即跳B由父IAB节点调度。为了避免该IAB节点调度的跳A的数据传输与父IAB节点调度的跳B的数据传输的冲突过大，因此对跳A和跳B采用保守调度，使得IAB节点的网络的频谱利用效率较低。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供一种资源配置方法、装置和设备，可应用于集成接入回传(Integrated Access Backhaul，IAB)系统中。在有线传输网部署不到位的情况下，IAB系统中IAB节点可依赖无线回传实现信息传输。图1为本申请提供的IAB系统的一实施例的结构示意图。如图1所示，IAB系统包括多个IAB节点和多个终端设备。每个IAB节点可接入一个或多个终端设备，在此并不限定。IAB节点可对应有父IAB节点(即parent IAB node)，IAB节点可对应有子IAB节点(即child IAB node)。如图1所示的三个IAB节点中，第二个IAB节点即为第一个IAB节点的父节点，第三个IAB节点即为第二个IAB节点的父节点。一个IAB节点与它的下游节点之间存在跨跳(即across hop)，该IAB节点与它的父IAB节点之间存在跨跳。为了便于说明，下面将“跨跳”称为“跳”。IAB节点的下 游节点可包括该IAB节点的子IAB节点或终端设备。IAB节点可调度该IAB节点与它的下游节点之间的跳，该IAB节点的父IAB节点可调度该IAB节点与它的父IAB节点之间的跳。IAB节点具体可实现为基站，在此并不限定。终端设备可实现为手机、电脑、平板电脑以及其他通信设备，在此并不限定。
一个IAB节点包括分布式单元(Distributed Unit，DU)和移动终端(Mobile Termination，MT)单元。依靠MT单元，一个IAB节点可以与一个父IAB节点的DU建立无线连接，从而建立IAB节点的回传链路。需要说明的是，在一个集成接入回传回路中包括一个宿主IAB节点(即donor IAB node)。宿主IAB节点不包括MT单元。图2为本申请实施例提供的IAB节点与中心单元(Centralized Unit，CU)的一示例的通信示意图。如图2所示，在一个集成接入回传回路中，所有IAB节点的DU连接到一个CU，由该CU对DU进行配置。所有IAB节点的MT单元连接到该CU，由该CU对MT单元进行配置。CU可具体实现为基站，在此并不限定。
本申请实施例提供一种资源配置方法，应用于CU。该CU与第一IAB节点、第二IAB节点通信。第一IAB节点与第二IAB节点分别调度第一IAB节点的第一跳和第二跳。具体地，第二IAB节点为第一IAB节点的父IAB节点，即第一IAB节点为第二IAB节点的子IAB节点。第一跳可为第一IAB节点与第一IAB节点的下游节点之间的跳，由第一IAB节点调度第一跳上的数据传输。第二跳可为第一IAB节点与第二IAB节点之间的跳，由第二IAB节点调度第二跳上的数据传输。图3为本申请提供的应用于中心单元的资源配置方法的一实施例的流程图。如图3所示，该资源配置方法可包括步骤S301和步骤S303。
在步骤S301中，确定第一跳和第二跳之间的复用模式。
第一IAB节点既参与第一跳的数据传输，又参与第二跳的数据传输。CU可预先确定第一跳和第二跳之间的复用模式，使得第一IAB节点在第一跳上的数据传输与第一IAB节点在第二跳上的数据传输处于该复用模式，从而提高IAB节点的网络的频谱利用效率。
具体地，CU可基于第一IAB节点的数据收发能力和/或第二IAB节点的数据传输能力，确定第一跳和第二跳之间的复用模式。在此并不限定CU确定第一跳和第二跳之间的复用模式的具体方式。
在步骤S302中，发送第一跳和/或第二跳的复用资源配置信息。
CU可发送第一跳的复用资源配置信息。CU可发送第二跳的复用资源配置信息。CU也可发送第一跳的复用资源配置信息和第二跳的复用资源配置信息。其中，复用资源配置信息用于表征上述步骤中复用模式的资源配置，从而使得接收到复用资源配置信息的IAB节点根据该复用资源配置信息进行资源配置。
具体地，CU可基于第一IAB节点的数据收发能力和/或第二IAB节点的数据传输能力，确定第一跳的复用资源配置信息和/或第二跳的复用资源配置信息。在此并不限定CU确定第一IAB节点的复用资源配置信息和第二IAB节点的复用资源配置信息的具体方式。
进一步地，CU向第一IAB节点发送第一跳的复用资源配置信息，以使第一IAB节点利用第一跳的复用资源配置信息，调度第一跳上的数据传输。和/或，CU向第二IAB节点发送第二跳的复用资源配置信息，以使第二IAB节点利用第二跳的复用资源配置信息，调度第二跳上的数据传输。
在本申请实施例中，CU确定第一IAB节点的第一跳和第二跳的复用模式，发送第一跳和/或第二跳的复用资源配置信息。其中，复用资源配置信息可表征该复用模式的资源配置。发送的第一跳和/或第二跳的复用资源配置信息，可使第一IAB节点基于第一跳的复用资源配置信息调度第一跳上的数据传输，和/或使第二IAB节点基于第二跳的复用资源配置信息调度第二跳上的数据传输。第一跳与第二跳采用复用模式进行数据传输，从而提高IAB节点的网络的频谱利用效率。
在一些示例中，复用资源配置信息可包括时域资源参数。时域资源参数可表征时域资源。比如，时域资源可包括时域上跳的数据传输占用的时间段。其中，时间段可包括符号(即symbol)、时隙(即slot)、子帧、子时隙(即sub-slot)、符号集合、时隙集合或子时隙集合等，在此并不限定。
复用资源配置信息还可包括以下的一项或多项：频域资源参数、复用模式参数、功率控制参数、周期参数、复用模式配置参数。
复用模式参数可表征第一跳和第二跳的复用模式。例如，复用模式可包括但不限于以下一种或多种：第一跳和第二跳空分复用发送、第一跳和第二跳空分复用接收、第一跳和第二跳频分复用发送、第一跳和第二跳频分复用接收、第一跳的上行接收和第二跳的上行发送同时同频复用、第一跳的下行发送和第二跳的下行接收同时同频复用、第一跳的上行接收和第二跳的上行发送同时不同频复用、第一跳的下行发送和第二跳的下行接收同时不同频复用。其他的资源复用模式也在本申请实施例的保护范围内，如单天线模块的同时同频全双工模式，在此并不一一进行举例说明。
下面为了便于说明，将第一跳和第二跳空分复用发送称为空分复用数据发送模式(即SDM TX模式)；将第一跳和第二跳空分复用接收称为空分复用数据接收模式(即SDMRX模式)；将第一跳和第二跳频分复用发送称为频分复用数据发送模式(即FDMTX模式)；将第一跳和第二跳频分复用接收称为频分复用数据发送模式(即FDM RX模式)；将第一跳的上行接收和第二跳的上行发送同时同频复用称为第一全双工模式；将第一跳的下行发送和第二跳的下行接收同时同频复用称为第二全双工模式；将第一跳的上行接收和第二跳的上行发送同时不同频复用称为第三全双工模式；将第一跳的下行发送和第二跳的下行接收同时不同频复用称为第四全双工模式。

在一些示例中，复用模式参数可具体用数字、字母、特殊符号或字符串等表示，在此并不限定。上述复用资源配置信息可承载于无线资源控制(Radio Resource Control，RRC)信令或F1-AP信令传输至第一IAB节点或第二IAB节点。

在另一些实施例中，该IAB节点还可接收CU发送的另一个IAB节点的至少部分复用资源配置信息，以获取另一个IAB节点调度的跳的资源配置情况。进一步地，该IAB节点还可基于IAB节点自身的复用资源配置信息和另一个IAB节点的复用资源配置信息，获取另一个IAB节点调度的跳的复用模式。
具体地，该IAB节点自身的复用资源配置信息可表征该IAB节点调度的跳的资源配置，另一个IAB节点的复用资源配置信息可表征另一个IAB节点调度的跳的资源配置，对比该IAB节点调度的跳的资源配置和另一个IAB节点调度的跳的资源配置，可确定另一个IAB节点调度的跳的资源复用模式。
例如，图9为本申请实施例提供的跳的资源模式的一示例的示意图。在本示例中，该IAB节点为另一IAB节点的子IAB节点，即该IAB节点可看作上述实施例中的第一IAB节点，另一IAB节点可看作上述实施例中的第二IAB节点。对应地，该IAB节点调度的为第一跳，另一IAB节点调度的为第二跳。第一跳和第二跳的资源配置如图9所示，第一跳在时隙0为HARDUL配置，在时隙1为HARDUL配置，在时隙6为HARD DL配置，在时隙7为HARD DL配置。第二跳在时隙0为HARDUL配置，在时隙1为HARDDL配置，在时隙6为HARDUL配置，在时隙7为HARD DL配置。
若该IAB节点接收到CU发送的另一个IAB节点的复用资源配置信息，得到另一个IAB节点调度的第二跳的资源配置。在时隙0，第一跳的资源配置为HARDUL配置，第二跳的资源配置为HARDUL配置，可确定第一跳和第二跳的资源复用模式为MPTR UL模式。在时隙1，第一跳的资源配置为HARDUL配置，第二跳的资源配置为HARDDL配置，可确定第一跳和第二跳的资源复用模式为SDM RX模式。在时隙6，第一跳的资源配置为HARDDL配置，第二跳的资源配置为HARDUL配置，可确定第一跳和第二跳的资源复用模式为SDM TX模式。在时隙7，第一跳的资源配置为HARDDL配置，第二跳的资源配置为HARDDL配置，可确定第一 跳和第二跳的资源复用模式为MPTR DL模式。
