具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机***中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
首先，对IAB网络中各节点的关系和链路进行说明。
图1是IAB网络中各节点的关系和链路的示意图，如图1所示，从上至下的三个节点分别称为父节点(parent node)，IAB节点和子节点(child node)或用户设备(User Equipment，UE)，图1中IAB节点所服务的节点为UE或子节点。
在版本-16(Release-16，Rel-16)中，IAB节点高优先级地支持上游(upstream)和下游(downstream)时分复用，但同时协议也前向兼容支持对其他复用方式的支持，例如频分多路复用(Frequency Division Multiplexing，FDM)、空分复用(Space Division Multiplexing，SDM)和全双工。IAB的分布单元(Distributed Unit，DU)充当基站功能通过下游为子节点或终端提供网络服务，IAB的MT单元通过上游与父节点相连。
DU资源是IAB节点的DU单元用于服务子节点或终端的资源，例如DU的下行链路(Downlink，DL)资源是IAB节点的DU单元为子节点或终端传输下游数据的资源。IAB节点的MT资源由网络侧半静态配置以及父节点的动态信令指示。IAB节点的DU单元的用于下游发送的资源可能对应着MT的用于上游发送的资源，在这种资源上IAB节点有机会同时进行下游发送和上游发送。IAB节点的DU单元的用于下游接收的资源可能对应着MT的用于上游接收的资源，在这种资源上IAB节点有机会同时进行下游接收和上游接收。
这种同时进行接收操作或同时进行发送操作的两个链路之间的干扰如何规避或协调需要考虑有效的方案，否则影响IAB节点下游和上游的传输性能。

x 1(n+31)＝(x 1(n+3)+x 1(n))mod2     式一
x 2(n+31)＝(x 2(n+3)+x 2(n+2)+x 2(n+1)+x 2(n))mod2

Figure PCTCN2021097734-appb-000002
Figure PCTCN2021097734-appb-000003
其中，式一为随机序列的生成方式，随机序列的初始序列由序列的初始值确定，如式二所示，根据随机序列生成参考信号序列如式三所示，用于参考信号序列生成的初始值如式四所示。发送方和测量方可以约定随机序列的生成方式，则IAB节点不用为父节点上报序列生成方式；若发送方和测量方约定序列初值产生方式，则IAB节点不用为父节点上报序列初值的产生方式；若IAB节点上游发送和IAB节点下游发送的时间对齐，则父节点可根据自身的定时确定序列初始化值的时间相关变量。如式四中的时间相关变量为时隙内的OFDM符号编号，无线帧之内的时隙编号。式四还包括对序列进行配置的变量。时间相关变量和对序列进行配置的变量用于干扰随机化或准正交多用户传输。
如图8所示，若无线网络的集中控制单元(Center Unit，CU)或操作维护管理(OAM，Operation Administration and Maintenance)为父节点指定了IAB节点的CSI-RS的配置则IAB节点不必告知父节点关于IAB节点的CSI-RS的映射位置，IAB节点将对应资源的索引号上报给父节点，父节点即可判断待测资源的位置。

父节点按照IAB节点上报的测量配置的资源集合对应的接收波束测量IAB节点上报的测量配置的资源集合中的参考信号或IAB节点上游发送的参考信号，若IAB节点上报的测量配置的参考信号配置不包含对应的准共址参考信号配置或对应的空间接收参数则父节点按照与IAB节点的历史接收参数进行相应的测量。测量量包括如下至少之一：RSRP，RSRQ，SINR，路损，SIR。

可选地，CSI-RS resource set的不同CSI-RS resource可对应不同的时域位置。IAB节点下游发送的CSI-RS可时分复用(Time Division Multiplexing，TDM)采用各自的波束发送。父节点可在不同时刻测量IAB节点的下游发送对父节点的干扰，父节点按照如上所述的方法反馈测量值，IAB节点在同时执行下游发送和上游发送时，IAB节点的下游发送避免采用对父节点造成干扰的波束。由于CSI-RS resource set的不同CSI-RS resource对应不同的时间资源，这种方式在IAB节点的下游发送不具备多波束同时发送能力的场景中可通过IAB节点在不同时间执行各自波束方向的下游发送达到父节点测量IAB节点的下游发送对父节点干扰测量的目的。IAB节点收到父节点的反馈，IAB节点即可确定IAB节点的下游发送对父节点造成干扰的波束，或IAB节点确定IAB节点的下游发送对父节点未造成干扰的波束。由此，IAB节点同时执行下游发送和上游发送时，其下游发送避免使用对父节点造成干扰的波束，或者下游发送采用对父节点干扰小的波束。
当IAB节点仅给父节点配置了一个CSI-RS resource set时，父节点可以基于上述反馈仅反馈set内的resource编号。
在一个实施例中，在上述实施例的基础上细化测量波束。

当父节点反馈以下情况之一或其组合则IAB节点认为CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引对应的下游发送传输未对父节点造成大的干扰：
父节点反馈RSRP_i小于或等于门限threshold_1的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引；父节点反馈RSRQ_s或SINR或CQI大于或等于门限threshold_2的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引；父节点反馈PL_i大于或等于门限threshold_3的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引；父节点反馈SIR_PL小于或等于门限threshold_4的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引；父节点反馈SIR小于或等于门限threshold_5的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引。
IAB节点接收到父节点反馈的测量值可以确定对父节点造成干扰的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引或者可以确定未对父节点造成干扰的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引，IAB节点同时执行下游发送和上游发送时，其下游发送避免使用对父节点造成干扰的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引对应的波束，或者下游发送采用对父节点干扰小的CSI-RS resource set索引、CSI-RS resource索引和参考信号端口索引对应的波束。
当IAB节点仅给父节点配置了一个CSI-RS resource set，父节点可以基于上述反馈仅反馈set内的对应的resource编号和对应端口。当IAB节点仅给父节点配置了一个CSI-RS resource set且resource set仅有一个resource，父节点可以基 于上述反馈仅反馈set内对应端口。

参考信号的发射功率为IAB节点上游发送的参考信号的发射功率。
UE或子节点按照IAB节点的测量配置的资源集合的接收波束测量IAB节点的参考信号。若IAB节点的测量配置的资源集合不包含接收波束则UE或子节点按照与IAB节点通信的历史接收波束进行相应的测量。

例如父节点向IAB节点配置IAB节点上游的空间接收参数为接收波束集合，记为TCI-state-set-1和TCI-state-set-2，其中，TCI-state-set-1的接收波束对应的时间为time-TCI-state-set-1，TCI-state-set-2的接收波束对应的时间为time-TCI-state-set-2。IAB节点收到父节点的配置确定在time-TCI-state-set-1对应的时间内采用TCI-state-set-1对应波束接收父节点发送的数据。基于父节点的配置，IAB节点在time-TCI-state-set-1对应的时间内调度UE或子节点。可选地，IAB节点在time-TCI-state-set-1对应的时间内调度UE或子节点发送数据使得传输满足以下之一或其组合：UE或子节点发送的数据对IAB节点上游接收没有干扰或干扰小；父节点的发送对IAB节点下游接收没有干扰或干扰小。
或者，父节点为IAB节点配置的接收波束集合的接收波束配置了各自的时间，则IAB节点对不同接收波束对应的时间取交集，确定对应时间的接收波束。
例如接收波束集合1的接收波束为波束1和波束2，接收波束1对应的时间为t1，接收波束2对应的时间为t2，t1和t2的重合部分即为t-overlap。则IAB节点可判断t1中除去t-overlap的时间对应接收波束1，在t-overlap时间对应接 收波束1和接收波束2，在t2中出去t-overlap的时间对应接收波束2。IAB节点根据对应时间的接收波束调度UE或子节点。基于父节点的配置，IAB节点在t1对应的时间内调度UE或子节点。可选地，IAB节点在t1对应的时间内调度UE或子节点发送数据使得传输满足以下之一或其组合：UE或子节点发送的数据对IAB节点上游接收没有干扰或干扰小；父节点的发送对IAB节点下游接收没有干扰或干扰小。

IAB节点按照父节点请求的CSI-RS资源配置的索引值或其子集发送对应的CSI-RS。
父节点测量IAB节点发送的CSI-RS resource，父节点将测量值反馈给IAB节点。父节点基于上述实施例以CSI-RS resource为粒度向IAB节点反馈。
父节点反馈以下之一或其组合表示父节点在对应CSI-RS resource set索引和CSI-RS resource索引测量到IAB节点下游发送对父节点的干扰：
