中继(Relay)技术，是在基站与终端之间增加了一个或多个中继节点，使无线信号经过一次或多次转发在基站与终端之间传输。比如，基站与终端之间的直接链路通信质量较差，则可采用中继技术，将基站与终端之间的直接链路替换为多个通信质量较好的链路，以达到提高通信质量的目的。多个通信质量较好的链路可包括基站与中继节点的链路、中继节点与终端的链路，还可包括中继节点与中继节点的链路。
随着通信技术的迅速发展，通信网络的频段越来越高。通信网络的频段越高，要求无线信号回传的距离越短，也就意味着中继节点的部署更加密集。部署密集的多个中继节点中传输的无线信号可能会相互干扰，从而降低通信质量。

具体实施方式
下面将详细描述本公开的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本公开的全面理解。但是，对于本领域技术人员来说很明显的是，本公开可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本公开的实施例来提供对本公开的更好的理解。本公开决不限于下面所提出的任何具体配置和算法，而是在不脱离本公开的精神的前提下覆盖了元素、部件和算法的任何修改、替换和改进。在附图和下面的描述中，没有示出公知的结构和技术，以便避免对本公开造成不必要的模糊。
在基站与终端进行通信的过程中，基站与终端之间传输的信号往往需要在基站和终端之间发生多次跳转，才能实现基站与终端的通信。基站和终端之间可设置多个中继节点，基站与终端之间传输的信号可通过中继节点转发。在本公开实施例中，基站、中继节点和终端均可视为网络中的节点。节点之间的通信可以为有线通信或无线通信，在此并不限定。
其中，中继节点可以为通常所用的中继节点，也可为具有接入回传一体化(Integrated Access and Backhaul，IAB)功能的中继节点，在此并不限定。
基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))或者小区cell等设备，或者后续的演进通信系统中的网络侧设备，在此并不限定。基站也可视为宿主中继节点，比如，基站也可为具有宿主接入回传一体化功能(Donor Integrated Access and Backhaul，DIAB)的基站。基站可以为一体化基站，也可以为包括集中式单元(Centralized Unit，CU)和分布式单元(Distributed Unit，DU)基站。其中，节点也可为基站中的DU。
终端可为手机、平板电脑、智能手表、智能家电等，在此并不限定。
图1为本公开实施例中一种应用场景示意图。如图1所示，通信网络中包括节点A1至A9。其中，节点A1为宿主(Donor)基站。节点A2至A8均为中继节点。节点A9为终端。由图1可得，在一条信号链路中，基站A1发出的信号依次经过中继节点A3、A4和A5，到达终端A9。在另一条信号 链路中，基站A1发出的信号依次经过中继节点A2和A4，到达中继节点A6。
在通信网络中，除基站和终端外的其他节点既可以作为父节点，也可以作为子节点。也就是说，通信网络中除基站和终端外的其他节点具有双向配置性。节点作为父节点或子节点可根据具体的工作场景和工作需求确定。比如，通信网络中包括5个节点，分别为节点A1至A5。其中节点A2为节点A3配置通信资源，节点A3为节点A4配置通信资源。则对于节点A2和节点A3来说，节点A2为父节点，节点A3为子节点。而对于节点A3和节点A4来说，节点A3为父节点，节点A4为子节点。可以得到，通信网络中的节点A3既可作为父节点，也可作为子节点。
需要说明的是，可选取除基站外的节点作为子节点，在子节点所在的信号链路中，在子节点与基站之间且与子节点连接的节点为该子节点的父节点。子节点向父节点发送数据，即为上行传输；父节点向子节点发送数据，即为下行传输。
基站可作为父节点，终端可作为子节点，中继节点既可作为父节点，也可作为子节点。如图1所示，假设中继节点A4为子节点，则中继节点A4的父节点为中继节点A2和中继节点A3。也就是说，中继节点A2和中继节点A3均可与中继节点A4进行通信。若中继节点A2与中继节点A4通信的时刻，中继节点A3与中继节点A4页在进行通信，则中继节点A2和中继节点A4通信的信号，与中继节点A3和中继节点A4通信的信号会相互干扰。
在本公开实施例中，为了避免多个父节点各自与同一子节点通信的信号相互干扰，由其中一个父节点为子节点进行时间资源的配置，可通知其他父节点已经为子节点配置了的时间资源，使得其他父节点在配置时间资源时，可避开已经配置了的时间资源，从而使得多个父节点为同一个子节点配置的用于传输信号的时间资源两两不重叠。
下面以一个子节点接入两个父节点为例进行说明，两个父节点分别为第一父节点和第二父节点。
图2为本公开实施例中一种资源分配方法的流程图。该资源分配方法的执行主体为第一父节点。如图2所示，该资源分配方法可包括步骤S101和步骤S102。
在步骤S101中，为子节点配置或预留第一通信资源。
其中，第一父节点为子节点的上行节点。第一父节点为子节点配置或预留的第一通信资源，为第一父节点与子节点通信占用的通信资源。
在步骤S102中，向第二父节点发送用于指示第一通信资源的资源指示信息，供第二父节点根据第一通信资源，为子节点配置或预留第二通信资源。
其中，第二父节点为子节点的上行节点。第二父节点为子节点配置或预留的第二通信资源，为第二父节点与子节点通信占用的通信资源。
第一通信资源与第二通信资源均为通信资源。通信资源为子节点用于通信的资源。为了降低第一父节点和第二父节点与子节点通信之间的干扰，第一父节点向第二父节点发送资源指示信息。以使得在考虑第一父节点的条件下，第二父节点为子节点配置或预留第二通信资源。
在本公开实施例中，在第一父节点为子节点配置或预留第一通信资源后，通过资源指示信息通知第二父节点第一通信资源，使得在考虑第一通信资源的基础上，第二父节点为子节点配置或预留第二通信资源。从而降低多个节点中传输的无线信号之间的相互干扰，进而提高通信质量。
在一些实施例中，第一通信资源和第二通信资源可均包括时间资源(time resource)，和/或第一通信资源和第二通信资源可均包括频段资源。
时间资源为子节点用于传输数据所占用的时间。子节点在第一父节点配置的时间资源内，传输与第一父节点之间交互的数据。比如，在节点采用时分双工(Time Division Duplexing，TDD)技术的场景中，父节点需要为子节点配置时间资源。
频段资源为子节点用于传输数据所占用的频段。子节点在第一父节点配置的频段资源内，传输与第一父节点之间交互的数据。比如，在节点采用频分双工(Frequency Division Duplexing，FDD)技术的场景中父节点需要为子节点配置频段资源。
在一些实施例中，子节点为中继节点。时间资源可包括回传时间资源(backhaul time resource)。回传时间资源为用于回传(backhaul)传输的时间资源。也就是说，在回传时间资源所指示的时间内，子节点向父节点发送数据，或者，子节点从父节点接收数据。若回传时间资源为第一父节点为子节 点配置的，即第一通信资源包括回传时间资源，则在该回传时间资源指示的时间内，子节点向第一父节点发送数据，或者，子节点从第一父节点接收数据。
回传时间资源可包括时间窗口内的上行回传时间资源和下行回传时间资源。上行回传时间资源为用于上行(Uplink)回传传输的时间资源。下行回传时间资源为用于下行(Downlink)回传传输的时间资源。时间窗口可为时长为预定时长的一段时间。在时间窗口内，可执行各类任务。在本公开实施例中，可在时间窗口中设置上行回传时间资源和下行回传时间资源。比如，时间窗口为时长为20分钟的一段时间。在该时间窗口中，0至第5分钟为上行回传时间资源，第10分钟至第15分钟为下行回传时间资源。
在一些实施例中，可在第一父节点为子节点配置的时间资源到来的预设时间段之前，第一父节点向第二父节点发送资源指示信息。从而减小或避开回传时延或子节点的内部处理时延的影响。其中回传时延可由父节点和/或子节点评估。子节点的内部处理时延可由子节点评估。
预设时间段可根据具体工作场景或工作需求设定，比如可设置为N个时隙(slot)或N个符号(symbol)，在此并不限定。
在另一些实施例中，子节点可为终端。时间资源可包括接入时间资源。接入时间资源为用于父节点与终端的接口(access link)接入(access)的时间资源。也就是说，在接入时间资源指示的时间内，终端向父节点发送数据，或者，终端从父节点接收数据。若接入时间资源为第一父节点为子节点配置的，则在该接入时间资源指示的时间内，子节点向第一父节点发送数据，或者，子节点从第一父节点接收数据。
接入时间资源可包括时间窗口内的上行接入时间资源和下行接入时间资源。上行接入时间资源为用于上行接入传输的时间资源。下行接入时间资源为用于下行接入传输的时间资源。在本公开实施例中，可在时间窗口内设置上行接入时间资源和下行接入时间资源。比如，时间窗口为时长为10分钟的一段时间。在该时间窗口中，第1分钟至第4分钟为上行接入时间资源。第6分钟至第9分钟为下行接入时间资源。
在一些实施例中，上行接入时间资源与下行接入时间资源可为时间窗口 内的非回传时间资源(non-backhaul time resource)。即接入时间资源与回传时间资源在同一个时间窗口内的交集为空集。也就是说，接入时间资源与回传时间资源在同一个时间窗口内不重叠。上行接入时间资源与下行接入时间资源的交集为空集。也就是说，在同一时刻，只能进行上行业务或下行业务，上行业务与下行业务不能在同一时刻进行。
在一些实施例中，上述第一通信资源与第二通信资源的交集为空集。或者，上述第一通信资源与第二通信资源之间无干扰。也就是说，第一父节点向第二父节点发送资源指示信息，第二父节点可避开第一通信资源，为子节点配置或预留第二通信资源。从而避免多个节点中传输的信号之间的相互干扰，进而提高通信质量。而且，还能够避免节点中发生传输拥塞，进而提高通信质量。
在一些实施例中，第一通信资源和第二通信资源均包括时间资源。则第二父节点为子节点配置或预留的时间资源，与第一父节点为子节点配置或预留的时间资源的交集为空集。也就是说，第二父节点为子节点配置的时间资源指示的时间与第一父节点为子节点配置的时间资源指示的时间不重叠。或者，第二父节点为子节点配置或预留的时间资源，与第一父节点为子节点配置或预留的时间资源之间无干扰。
比如，第一父节点为子节点配置或预留的时间资源指示的时间为时间窗口中的0至第5分钟，则第二父节点为子节点配置或预留的时间资源指示的时间需要避开时间窗口中的0至第5分钟。例如，第二父节点为子节点配置的时间资源指示的时间可为第8分钟至第13分钟。
在另一些实施例中，第一通信资源和第二通信资源均包括频段资源。则第二父节点为子节点配置或预留的频段资源，与第一父节点为子节点配置或预留的频段资源的交集为空集。也就是说，第二父节点为子节点配置的频段资源指示的频段与第一父节点为子节点配置的频段资源指示的频段不重叠。或者，第二父节点为子节点配置或预留的频段资源，与第一父节点为子节点配置或预留的频段资源之间无干扰。
比如，第一父节点为子节点配置的频段资源指示的频段为1920兆赫兹(MHz)至1980MHz，则第二父节点为子节点配置的频段资源指示的频段需 要避开920MHz至1980MHz的频段。例如，第二父节点为子节点配置的频段资源指示的频段可为1710MHz至1785MHz。
在本公开实施例中，在第一父节点为子节点配置通信资源后，通过资源指示信息通知第二父节点第一父节点为子节点配置的通信资源，使得第二父节点为子节点配置的通信资源可避开第一父节点为子节点配置的通信资源。
在一些实施例中，在第一通信资源包括时间资源的情况下，上述资源指示信息还可包括子节点标识(Identification，ID)和时间模式(时间pattern)。子节点标识用于标识子节点。子节点标识具有唯一性，即不同的子节点的子节点标识不同。时间模块用于指示时间窗口的起始时间。比如，在时间资源只指示了时间的时长和分布的情况下，结合时间窗口和时间模式，可确定时间窗口的具体时间。比如，时间窗口为时长为20分钟的时间，且时间模式指示时间窗口的起始时间为上午10:00，则时间窗口的具体时间为上午10:00至上午10:20。
在一些实施例中，在第一父节点向第二父节点发送用于指示第一通信资源的资源指示信息之前，第一父节点还可接收来自子节点的第二父节点的节点信息。节点信息包括节点标识，该节点标识即为第二父节点的节点标识。
其中，第二父节点的节点信息是第二父节点通过广播，而使子节点得到的。
在一些实施例中，节点信息还可包括资源占用信息。资源占用信息用于指示该节点已被占用的资源情况。具体地，资源占用信息可包括负载(Load)信息。
在实际的通信过程中，子节点可能会由于链接错误等原因与第一父节点断开链接。子节点需要尽快选择并接入新的父节点(比如第二父节点)。第一父节点接收到第二父节点的节点信息后，可根据节点信息尽快通过资源指示信息将第一通信资源告知第二父节点，从而使得第二父节点可提前为子节点配置或预留第二通信资源，保证子节点可快速接入第二父节点。
图3为本公开实施例中的资源分配方法的另一流程图。该资源分配方法的执行主体为第二父节点。如图3所示，该资源分配方法可包括步骤S201和步骤S202。
在步骤S201中，接收来自第一父节点或子节点的用于指示第一通信资源的资源指示信息，并根据资源指示信息，确定第一父节点为子节点配置或预留的第一通信资源。
需要说明的是，资源指示信息可以来自第一父节点。也就是说，第一父节点在为子节点配置或预留第一通信资源后，可根据第一通信资源生成资源指示信息，并将资源指示信息向第二父节点发送。
资源指示信息也可来自子节点。也就是说，在第一父节点在为子节点配置或预留第一通信资源，且子节点得知第一通信资源后，子节点可根据第一通信资源生成资源指示信息，并将资源指示信息向第二父节点发送。
在步骤S202中，根据第一通信资源，为子节点配置或预留第二通信资源。
其中，步骤S201至步骤S202中与第一通信资源、第二通信资源、资源指示信息的相关说明可参见上述实施例中的相关内容，在此不再赘述。

在一些实施例中，在第一父节点为子节点配置的时间资源到来的预设时间段之前，第二父节点接收来自第一父节点或子节点的资源指示信息。从而减小或避开回传时延或子节点的内部处理时延的影响。其中回传时延可由父节点和/或子节点评估。子节点的内部处理时延可由子节点评估。
预设时间段的相关说明可参见上述实施例中的相关内容，在此不再赘述。
在一些实施例中，在第二父节点接收来自第一父节点或子节点的用于指示第一通信资源的资源指示信息之前，第二父节点广播第二父节点的节点信息。以使得子节点可将第二父节点的节点信息向第一父节点发送，便于第二父节点与第一父节点交互信息，使得第二父网路节点可根据第一通信资源，为子节点配置或预留第二通信资源。使得子节点快速接入第二父节点。

在一些实施例中，在第一父节点为子节点配置的时间资源到来的预设时间段之前，子节点向第二父节点发送资源指示信息。从而减小或避开回传时延或子节点的内部处理时延的影响。其中回传时延可由父节点和/或子节点评估。子节点的内部处理时延可由子节点评估。
预设时间段的相关说明可参见上述实施例中的相关内容，在此不再赘述。
在一些实施例中，在子节点向第二父节点发送用于指示第一通信资源的资源指示信息之，子节点获取第二父节点广播的节点信息。子节点向第一父节点发送第二父节点的节点信息。便于第二父节点与第一父节点交互信息，使得第二父网路节点可根据第一通信资源，为子节点配置或预留第二通信资源。使得子节点快速接入第二父节点。
