IAB节点在接入网络时，IAB DU给UE提供服务的链路称为接入链路(Access link,AC),向其他IAB节点发送数据的链路称为回传链路(backhaul link,BH)，由于在不同的IAB节点处调度结果有所不同，会导致不同的IAB节点在同一时刻的收发状态可能有所不同，例如当一个IAB节点正在接收回程链路或者接入链路上传输的信号时，会收到另一个IAB节点发送的信号的干扰，即称为交叉链路干扰(cross link interference,CLI)。交叉链路干扰会使得IAB节点的传输能力下降，特别是对于回程链路的干扰，会造成严重的性能损失。因此，如何对IAB节点进行干扰测量，进而能有针对性地采取干扰管理措施，避免出现交叉链路干扰或者缓解交叉链路在传输信号带来的影响，是当前IAB标准化需要考虑的问题。

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。
图1为本申请实施例提供的通信系统的示意图。如图1所示，通信系统包括网络设备和至少一个终端设备，其中，终端设备处在网络设备覆盖范围内并与网络设备进行通信，以实施下述各本申请实施例提供的技术方案。本实施例的通信系统可以应用于多TRP场景。
本申请实施例结合网络设备和终端设备描述了各个实施例，该网络设备和终端设备可以工作在许可频段或免许可频段上，其中：
终端设备也可以称为用户设备(User Equipment，UE)、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。终端设备可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(STATION，ST)，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)设备、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、可穿戴设备以及下一代通信系统，例如，第五代通信(the fifth-generation，5G)网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备，NR系统中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，网络设备又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端设备接入到无线网络的设备，可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，或NR系统中的新一代基站(new radio Node B，gNodeB)等，在此并不限定。
另外，在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信。该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站。这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1为本申请实施例所适用的通信系统的结构示意图。
需要说明的是，本申请实施例提及的通信系统包括但不限于：窄带物联网(narrow  band-internet of things，NB-IoT)系统、长期演进(long term evolution，LTE)系统，下一代5G移动通信系统或者5G之后的通信系统，或者设备到设备(device to device，D2D)通信系统。
在图1所示的通信系统中，给出了一体化的接入和回程IAB系统。一个IAB系统至少包括一个基站100，及基站100所服务的一个或终端101，一个或多个中继节点(relay transmission reception point,rTRP)110，及该rTRP 110所服务的一个或多个终端111，通常基站100被称为宿主基站(donor next generation node B，DgNB)，rTRP 110通过无线回程链路113连接到基站100。本申请中，终端又被称为终端，宿主基站在也称为宿主节点，即，Donor节点。基站包括但不限于：演进型节点B(evolved node base，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 nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)、或下一代新空口基站(比如gNB)等。
一体化的接入和回程系统还可以包括多个其他中继节点，例如rTRP 120和rTRP 130，rTRP 120是通过无线回程链路123连接到中继节点rTRP 110以接入到网络的，rTRP 130是通过无线回程链路133连接到中继节点rTRP 110以接入到网络的，rTRP 120为一个或多个终端121服务，rTRP 130为一个或多个终端131服务。图1中，中继节点rTRP 110和rTRP 120都通过无线回程链路连接到网络。在本申请中，所述无线回程链路都是从中继节点的角度来看的，比如无线回程链路113是中继节点rTRP 110的回程链路，无线回程链路123是中继节点rTRP 120的回程链路。如图1所示，一个中继节点，如120，可以通过无线回程链路，如123，连接另一个中继节点110，从而连接到网络，而且，中继节点可以经过多级无线中继节点连接到网络。
通常，把提供无线回程链路资源的节点，如110，称为中继节点120的上级节点，而120则称为中继节点110下级节点。通常，下级节点可以被看作是上级节点的一个终端。应理解，图1所示的一体化接入和回程系统中，一个中继节点连接一个上级节点，但是在未来的中继系统中，为了提高无线回程链路的可靠性，一个中继节点，如120，可以有多个上级节点同时为其提供服务，如图中的rTRP 130还可以通过回程链路134连接到中继节点rTRP 120，即，rTRP 110和rTRP 120都为rTRP 130的上级节点。在本申请中，所述终端101,111,121,131，可以是静止或移动设备。例如移动设备可以是移动电话，智能终端，平板电脑，笔记本电脑，视频游戏控制台，多媒体播放器，甚至是移动的中继节点等。静止设备通常位于固定位置，如计算机，接入点(通过无线链路连接到网络，如静止的中继节点)等。中继节点rTRP 110,120，130的名称并不限制其所部署的场景或网络，可以是比如relay，RN等任何其他名称。本申请使用rTRP仅是方便描述的需要。
一个或多个中继节点rTRP 110，又可以被称为IAB节点，每个IAB节点包括分布式单元(Distributed Unit,DU)和移动终端(Mobile Termination)两部分功能实体，其中MT功能实体类似于UE的功能，从上级节点(Donor节点或者IAB节点)接收下行数据或向上级节点发送上行数据，DU功能实体类似于基站功能，向下级节点(IAB节点或移动终端)发送下行数据或接收下级节点发送的上行数据，例如针对图2提供IAB系统而言，所述IAB系统包括：一个Donor节点，三个IAB节点分别为IAB节点1、IAB节点2和IAB节 点3。其中，IAB节点2和IAB节点3直接接入Donor节点，IAB节点1为IAB节点3的子节点，Donor节点与各IAB节点分别服务一个或多个用户UE节点，例如：UE1，UE2，UE3以及UE4。
在图1中，无线链路102,112,122,132,113,123，133,134可以是双向链路，包括上行和下行传输链路，特别地，无线回程链路113,123，133,134可以用于上级节点为下级节点提供服务，如上级节点100为下级节点110提供无线回程服务。应理解，回程链路的上行和下行可以是分离的，即，上行链路和下行链路不是通过同一个节点进行传输的。所述下行传输是指上级节点，如节点100，向下级节点，如节点110,传输信息或数据，上行传输是指下级节点，如节点110，向上级节点，如节点100，传输信息或数据。所述节点不限于是网络节点还是终端，例如，在D2D场景下，终端可以充当中继节点为其他终端服务。无线回程链路在某些场景下又可以是接入链路，如回程链路123对节点110来说也可以被视作接入链路，回程链路113也是节点100的接入链路。应理解，上述上级节点可以是基站，也可以是中继节点，下级节点可以是中继节点，也可以是具有中继功能的终端，如D2D场景下，下级节点也可以是终端。
图1中，Donor节点是指通过该节点可以接入到核心网的节点，或者是无线接入网的一个锚点基站，通过该锚点基站可以接入到网络。锚点基站负责分组数据汇聚协议(packet data convergence protocol，PDCP)层的数据处理，或者负责接收核心网的数据并转发给中继节点，或者接收中继节点的数据并转发给核心网。
当中继节点在半双工约束下，带内中继的无线回程链路与接入链路的频谱资源重合，即，带内中继的回传链路与接入链路具有相同频段。如，rTRP在基站的下行无线回程链路进行接收时，就不能向下属终端或设备进行传输；而rTRP在回程链路上向上级节点进行上行传输时，不能接收下属终端或设备在上行接入链路或下级节点的回程链路上的传输。应理解，带内中继的半双工约束指的是同时同频收发的半双工约束，与系统本身采用的时分双工(Time Division Duplexing,TDD)或频分双工方式(Frequency Division Duplexing,FDD)无关。
下面对一些常用的技术术语给出如下定义：
接入链路：接入链路是指某个节点和它的下级节点进行通信时所使用的无线链路，包括上行传输和下行传输的链路。接入链路上的上行传输也被称为接入链路的上行传输，下行传输也被称为接入链路的下行传输。其中的节点包括但不限于前述IAB节点。
回传链路：回传链路是指某个节点和它的上级节点进行通信时所使用的无线链路，包括上行传输和下行传输的链路。回传链路上的上行传输也被称为回传链路的上行传输，下行传输也被称为回传链路的下行传输。其中的节点包括但不限于前述IAB节点。
对于波束(beam)，可以理解为空间资源，可以指具有能量传输指向性的发送或接收预编码向量。并且，该发送或接收预编码向量能够通过索引信息进行标识。其中，能量传输指向性可以指通过该预编码向量对所需发送的信号进行预编码处理，经过该预编码处理的信号具有一定的空间指向性，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等；所述能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。可选地，同一通信设备，比如终端设备或网络设备，可以有不同的预编码向量，不同的通信设备也可以有不同的预编 码向量，即对应不同的波束。
针对通信设备的配置或者能力，一个通信设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。波束信息可以通过索引信息进行标识，可选地，所述索引信息可以对应配置终端设备的资源标识(identity，ID)。例如，所述索引信息可以对应配置的信道状态信息参考信号(Channel status information Reference Signal，CSI-RS)的ID或者索引(index)或资源，也可以是对应配置的上行探测参考信号(Sounding Reference Signal，SRS)的ID或者资源。或者，可选地，所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息，比如，所述索引信息包括但是不限于通过波束发送的同步信号或者广播信道指示该波束的索引信息。该资源可以是以下至少一种：时域、频域、码域(序列)。
应当理解，本文中使用的术语“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，由于5G NR支持高频段，并且采用了大规模天线技术(Massive MIMO)，使得信号的能量可以集中的向某个方向传输，这样使得IAB设备可以同时接收多个方向传输过来的信号，下面再介绍IAB中空分传输中的一些系统组成示意图，如图2所示。
图2所示，IAB系统包括：IAB设备，例如：IAB节点1，IAB节点2，IAB节点3，各IAB设备所服务的终端设备UE以及Donor节点。其中Donor节点是IAB节点2的上级节点或者父节点，所述IAB节点2可以与Donor节点进行信号传输，又为UE2提供服务，与此同理，IAB节点1的上级节点为IAB节点3，IAB节点1与所搜IAB节点3进行信号传输，也为UE1提供服务。
根据图2的场景，下面通过图3具体介绍各种应用场景下的干扰测量。
图3中，场景1即case1下，IAB节点1通过MT在接收Donor节点发送的信号，IAB节点2通过MT发送数据给IAB节点3。这时IAB节点1的MT在接收下行信号时，受到IAB节点2的MT的发送上行信号的干扰，这里的干扰源是IAB节点2，受干扰节点是IAB节点1，交叉链路干扰CLI是IAB节点2的MT对IAB节点1的MT产生的干扰。
图3中，场景2即case2下，IAB节点1通过MT在接收Donor节点发送的信号，IAB节点2通过DU发送信号给UE。这时IAB节点1的MT在接收下行信号时，受到IAB节点2的DU发送下行信号的干扰，这里的干扰源是IAB节点2的DU，受干扰节点是IAB节点1的MT，交叉链路干扰是IAB节点2的DU对IAB节点1的MT产生的干扰。
图3中，场景3即case3下，IAB节点1通过DU在接收UE发送的信号，IAB节点2通过MT发送信号给IAB节点3。这时IAB节点1的DU在接收上行信号时，受到IAB节点2的MT发送上行信号的干扰，这里的干扰源是IAB节点2的MT，受干扰节点是IAB节点1的DU，交叉链路干扰是IAB节点2的MT对IAB节点1的DU产生的干扰。
图3中，场景4即case4下，IAB节点1通过DU在接收UE发送的信号，IAB节点3通过DU发送IAB节点2的信号。这时IAB节点1的DU在接收上行信号时，受到IAB节点3的DU的发送下行信号的干扰，这里的干扰源是IAB节点3的DU，受干扰节点是IAB节点1的DU，交叉链路干扰CLI是IAB节点3的DU对IAB节点1的DU产生的干扰。
实施例一：
图4a为本申请实施例提供的一种干扰测量方法流程图，下面以图5所示的IAB网络架构为例，对干扰测量方法进行详细描述，上述的各种应用场景都可以应用到下面的干扰测量方法。
图5中，IAB节点1通过MT在接收IAB节点3的DU发送的信号，IAB节点2通过MT发送数据给Donor节点。这时IAB节点1的MT在接收下行信号时，受到IAB节点2的MT发送的上行信号的干扰，这里的干扰源是IAB节点2，受干扰节点是IAB节点1，所述干扰具体可以是交叉链路干扰CLI，所述CLI是IAB节点2的MT对IAB节点1的MT产生的干扰。
如图5所示，IAB节点1和IAB节点2在部分时隙上可能存在MT与MT之间的交叉链路干扰，因此需要完成IAB节点1的MT与IAB节点2的MT之间的交叉链路干扰的测量，具体干扰测量方法如下：
S400、第一节点发送参考信号(reference signal,RS)配置消息，所述RS配置消息包括：第二节点的第二功能实体的参考信号资源指示信息，所述第二功能实体的参考信号资源指示信息包括：第二节点的第一功能实体的参考信号资源标识。其中，所述RS配置信息用于对所述第二节点的第二功能实体发送的参考信号进行配置，所述第二节点的第二功能实体发送的参考信号用于干扰测量，所述干扰为第二节点的第一功能实体对第三节点的第一功能实体产生的干扰。
所述第二节点为产生干扰的节点，所述第三节点为受干扰的节点；所述第二节点的第一功能实体的参考信号资源标识用于指示所述参考信号资源。
在如图5所示的IAB网络中，第一节点为Donor节点，第二节点为产生干扰的节点例如IAB节点2，所述第三节点为受干扰的节点，例如IAB节点1。无论第二节点还是第三节点均可以包括第一功能实体和第二功能实体。其中，所述第一功能实体为MT，第二功能实体为DU。这里第一功能实体可以与第二功能实体进行集成为一个模块，也可以各自独立、分开为不同的模块。所述第一功能实体为MT，或者DU，所述第二功能实体为DU或者，MT。所述第一节点也可以为IAB node节点。
根据IAB节点2或者IAB节点1的配置或者能力，IAB节点2在同一时刻可以使用一个波束或者多个波束进行信号传输，IAB节点1在同一时刻也可以使用一个或者多个波束进行信号传输。所述波束可以通过参考信号资源标识进行指示。所述第二节点的第一功能实体的参考信号资源标识为IAB节点2的MT的参考信号资源标识，用于指示IAB节点2的MT进行参考信号发送时使用的一个或者多个参考信号资源，所述一个或者多个参考信号资源对应一个或者多个MT的发送波束。可选地，第二节点的第一功能实体的参考信号资源标识可以为配置IAB节点的参考信号的资源标识(identity，ID)，例如：信道状态信息参考信号(Channel status information Reference Signal，CSI-RS)的资源标识(CSI-RS-ResourceId)或者探测参考信号(Sounding Reference Signal，SRS)的资源标识(SRS-ResourceId)。
其中，所述参考信号配置消息可以承载在无线资源控制(Radio Resource Control,RRC)协议消息中，或者，通过F1接口承载在基于F1-AP(F1-application protocol)协议的消息中，例如：下行无线资源控制转移消息(DL RRC TRANSFER message)，所述F1接口为IAB节 点2的分布单元(distributed unit,DU)与Donor节点的集中单元(central unit,CU)之间的F1接口，或者承载在DCI(Downlink Control Information)消息或MAC CE(Media Access Control control element)中。
所述参考信号配置消息还可以是由Donor节点通过RRC、DCI或MAC CE发送给IAB节点2的MT，再由IAB节点2的MT通过内部的信令交互通知IAB节点2的DU。
所述参考信号配置消息可以是周期性发送的，也可以是半静态发送的。
所述参考信号配置消息包括：一个或者多个参考信号资源指示信息，每个参考信号资源指示信息包含参考信号资源标识。
具体所述参考信号资源指示信息格式如下：
1、方式一：定义一种新的参考信号资源指示信息，具体指示信息的格式示例如下：
Figure PCTCN2019108123-appb-000001
其中，RS-Resource为参考信号资源指示信息；
RS-ResourceId为参考信号资源标识，所述参考信号资源标识可以理解为指示IAB节点2的DU使用该标识对应的IAB节点2的MT的波束发送所述参考信号。
可选地，所述参考信号资源指示信息还可以包括下面一种或者几种：
resource Mapping：用于指示干扰测量的参考信号映射的时频资源位置；
powercontrol：参考信号的功率控制。所述参考信号的功率控制指示了IAB节点2的DU发送参考信号使用的发射功率。其中，所述参考信号的发射功率配置为IAB节点2的MT的发射功率。
periodicityAndOffset：指示了所述用于干扰测量对的参考信号的发送周期，和/或每个周期内的时隙偏移量。
2、方式二：所述参考信号资源指示信息采用统一的格式，例如采用现有的CSI-RS-Resource消息格式，通过对所述CSI-RS-Resource消息进行扩展。
具体如下：
如下所示的CSI-RS资源指示信息CSI-RS-Resource：
Figure PCTCN2019108123-appb-000002
其中，CSI-RS-Resource为参考信号资源指示信息；
CSI-RS-ResourceId为常规的用于CSI测量的参考信号资源标识，用于指示IAB节点 2的DU采用DU的自身配置的波束发送用于CSI测量的参考信号；
SRS-ResourceId为参考信号资源标识，所述参考信号资源标识用于指示IAB节点2的DU使用该标识对应的IAB节点2的MT的波束发送所述参考信号。
resourceMapping：用于指示参考信号映射的时频资源位置；
powercontrol：参考信号的功率控制，指示了IAB节点2的DU发送参考信号使用的发射功率；
periodicityAndOffset：指示了所述用于干扰测量对的参考信号的发送周期，和/或每个周期内的时隙偏移量。
当Donor节点发送参考信号配置消息给IAB节点2的DU时，如果所述IAB节点2的DU识别出其中包含的SRS-ResourceId，可知当前的参考信号配置是用于干扰测量的，具体为交叉链路干扰测量。
powerControl字段指示了发送参考信号使用的功率，如果当前指示的是用于信道状态信息CSI测量的参考信号资源，则该字段将设置为CSI-RS的发送功率信息；当指示的是交叉链路干扰CLI测量参考信号资源时，该字段将设置为SRS的发送功率信息。
具体步骤S400以图5为例，可以理解为：
当IAB节点1的MT受到IAB节点2的MT的干扰时，Donor节点生成RS配置消息，所述RS配置消息用于对IAB节点2的DU发送的用于干扰测量的参考信号进行配置，所述干扰测量的参考信号用于IAB节点1的MT对IAB节点2的MT带来的干扰进行测量，其中，所述RS配置消息包括：IAB节点2的DU的参考信号资源标识例如：{3,4,5}，所述参考信号资源标识对应于IAB节点2的MT的波束。
S402、第二节点的第二功能实体根据接收的RS配置消息，对用于干扰测量的参考信号进行配置。
如图5所示，所述IAB节点2的DU根据参考信号资源标识，选择对应的波束发送参考信号。
对于IAB节点2的MT，参考信号资源标识与传输信号具体使用的波束的对应关系是知道的，而在IAB节点2内部，DU可以与MT进行交互，从而DU也可以识别出SRI{3,4,5}对应的MT的波束具体为哪些，例如图5中阴影标识的3个物理波束。
例如:所述IAB节点2的MT使用参考信号资源标识{3,4,5}对应的波束集合{a,b,c}进行信号传输，当IAB节点1的MT对IAB节点2的MT进行干扰测量时，IAB节点2的DU与IAB节点2的MT进行交互，获得与所述参考信号资源标识{3,4,5}对应的IAB节点2的MT的波束集合{a,b,c}，IAB节点2的DU采用束集合{a,b,c}发送用于干扰测量的参考信号。
需要说明的是，所述IAB节点2的MT与DU的交互可以是硬件模块之间的交互，也可以是所述MT和DU进行集成时，通过软件实现上述交互。进一步地，所述配置消息中的参考信号资源指示信息还包括：下面一种或者多种组合：
IAB节点2的DU的参考信号映射的时频资源，IAB节点2的DU的参考信号发送功率，或者，IAB节点2的DU的参考信号的发送周期。
由于IAB节点2的DU需要根据IAB节点2的MT的配置信息对用于干扰测量的参考信号进行配置，通过IAB节点2的DU代替IAB节点2的MT发送所述参考信号，使 得IAB节点1能够准确地检测到干扰测量的参考信号，从而对干扰进行测量，进而对干扰进行消除，极大地提升了IAB网络的性能。
S404、第二节点的第二功能实体发送用于干扰测量的参考信号。
如图5所示，IAB节点2的DU采用RS配置消息中的参考信号资源标识对应的一个或者多个波束发送干扰测量的参考信号，便于IAB节点1的MT进行干扰测量。
进一步地，IAB节点2的DU还可以在指定的时频资源上发送用于干扰测量的参考信号，如果需要进行周期性地测量，IAB节点2的DU还会在指定的发送周期内，周期性发送该参考信号，以及使用指定的发送功率发送上述参考信号。
所述参考信号可以包括如下一种或者几种：同步信号SSB,信道状态信息参考信号CSI-RS,解调参考信号DMRS,跟踪参考信号TRS,相位跟踪参考信号PTRS,探测参考信号SRS,或其他RS。
S406、第一节点对第三节点的第一功能实体进行干扰测量配置，发送干扰测量配置消息。
所述步骤S406可以在步骤S404发送用于干扰测量的参考信号之前进行，不限制于在步骤S404之后。
如图5所示，Donor节点向IAB节点1的MT发送的干扰测量配置消息可以基于RRC(Radio Resource Control,无线资源控制)协议由Donor向IAB节点1的MT发送，承载在RRC协议的特定消息中。也可以通过MAC CE来指示。
如图5所示，Donor在对IAB节点1的MT进行干扰测量配置时，按照常规的测量配置方法对其进行干扰测量配置，也就是说IAB节点1对该测量配置是用于干扰测量不感知，例如可以按照常规的用于移动性测量的配置来进行配置。发送给IAB节点1的MT的干扰测量配置消息中，将包含具体的参考信号资源指示信息，例如参考信号的时频资源位置、周期等。其中还包含参考信号资源标识，而这里的参考信号资源标识个数，也就是需要测量的参考信号资源个数与Donor发送给IAB节点2的DU的参考信号资源个数是一致的。
S408、第三节点的第一功能实体根据步骤S406所述的测量配置，检测到第二节点的第二功能实体发送的用于干扰测量的参考信号，进行干扰测量。
如图5所示，IAB节点1的MT收到所述测量配置后，便在指示的资源位置上对IAB节点2的DU发送的用于干扰测量的参考信号进行检测。
针对上述实施例一，本本发明实施例还提供另一种实施例，以所述第二节点简单描述上述过程，如图4b所示：
一种干扰测量方法，应用在集成接入和回传IAB网络，所述IAB网络至少包括：第一节点和第二节点，所述第二节点包括：第一功能实体和第二功能实体，所述方法包括：
S400’、所述第二节点的第二功能实体接收参考信号配置消息，所述参考信号配置消息包括：第二节点的第二功能实体的参考信号资源指示信息，所述第二功能实体的参考信号资源指示信息包括：第二节点的第一功能实体的参考信号资源标识。
进一步地，所述参考信号资源指示信息还包括下面一种或多种的任意组合：
用于所述干扰测量的RS映射的时频资源位置、用于干扰测量的RS的功率控制、用于干扰测量的RS发送周期。
S402’、第二节点的第二功能实体根据接收到的参考信号配置消息中的第二节点的第 一功能实体的参考信号资源标识，发送用于干扰测量的RS。
具体为：所述第二节点的第二功能实体根据接收到的参考信号配置消息中的第二节点的第一功能实体的参考信号资源标识，确定所述第二节点的第一功能实体的参考信号资源标识对应的一个或者多个波束；
所述第二节点的第二功能实体使用所述确定的一个或者多个波束发送所述用于干扰测量的RS。
进一步地，所述用于干扰测量的RS的功率控制为第二节点的第一功能实体的发送功率。
进一步地，在所述步骤S400’之前，所述方法还包括：
所述第一节点生成所述参考信号配置消息。
上述的方法流程也适用与图4a,4b以及图5对应的实施例的描述，具体请参见相应的实施例的具体描述，这里就不再赘述。
本申请提供一种干扰测量方法和装置，通过产生干扰的节点的第二功能实体通使用所述产生干扰的节点的第一功能实体的参考信号资源标识对应的一个或者多个波束发送用于干扰测量的RS，使得受到干扰的节点能快速、准确进行干扰测量，进而极大地降低了交叉链路在传输信号带来的影响，提高了系统的传输性能。
实施例二：
本发明实施例还提供另一种实施例，如图6所示。
以图7的IAB的组网架构图为例进行举例说明，但是不限制于图7，可以应用到上面的各种组网架构图中。
图7中，IAB节点1通过MT在接收IAB节点3的DU发送的信号，IAB节点2通过MT发送数据给Donor节点。这时IAB节点1的MT在接收下行信号时，受到IAB节点2的MT发送的上行信号的干扰，这里的干扰源是IAB节点2，受干扰节点是IAB节点1，所述干扰具体可以是交叉链路干扰CLI，所述CLI是IAB节点2的MT对IAB节点1的MT产生的干扰。
如图7所示，IAB节点1和IAB节点2在部分时隙上可能存在MT与MT之间的交叉链路干扰，因此需要完成IAB节点1的MT与IAB节点2的MT之间的交叉链路干扰的测量，具体干扰测量方法如下：
在如图7所示的IAB网络中，第一节点为Donor节点，第二节点为产生干扰的节点例如IAB节点2，所述第三节点为受干扰的节点，例如IAB节点1。无论第二节点还是第三节点均可以包括第一功能实体和第二功能实体。其中，所述第一功能实体为MT，第二功能实体为DU。这里第一功能实体可以与第二功能实体进行集成为一个模块，也可以各自独立、分开为不同的模块。所述第一功能实体为MT，或者DU，所述第二功能实体为DU或者，MT。所述第一节点也可以为IAB node节点。
S600、第一节点发送干扰测量指示消息，所述干扰测量指示消息用于指示第二节点的第二功能实体上报用于干扰测量的参考信号配置消息。
如图7，Donor节点向IAB节点2的DU发送干扰测量指示消息，指示IAB节点2的DU生成用于干扰测量的参考信号配置信息，并进行上报。
其中，所述干扰测量指示消息可以承载在无线资源控制(Radio Resource Control,RRC) 协议消息中，或者，通过F1接口承载在基于F1-AP(F1-application protocol)协议的消息中，例如：下行无线资源控制转移消息(DL RRC TRANSFER message)，所述F1接口为IAB节点2的分布单元(distributed unit,DU)与Donor节点的集中单元(central unit,CU)之间的F1接口。

SRS-ResourceId为参考信号资源标识，所述参考信号资源标识用于指示IAB节点2的DU使用该标识对应的IAB节点2的MT的波束发送所述参考信号。
resourceMapping：用于指示参考信号映射的时频资源位置；
powercontrol：参考信号的功率控制，指示了IAB节点2的DU发送参考信号使用的发射功率；
periodicityAndOffset：指示了所述用于干扰测量对的参考信号的发送周期，和/或每个周期内的时隙偏移量。
当Donor节点发送参考信号配置消息给IAB节点2的DU时，如果所述IAB节点2的DU识别出其中包含的SRS-ResourceId，可知当前的参考信号配置是用于干扰测量的，具体为交叉链路干扰测量。
powerControl字段指示了发送参考信号使用的功率，如果当前指示的是用于信道状态信息CSI测量的参考信号资源，则该字段将设置为CSI-RS的发送功率信息；当指示的是交叉链路干扰CLI测量参考信号资源时，该字段将设置为SRS的发送功率信息。
具体步骤S1400以图15为例，可以理解为：
当IAB节点1的DU受到IAB节点2的MT的干扰时，Donor节点生成RS配置消息，所述RS配置消息用于对IAB节点2的DU发送的用于干扰测量的参考信号进行配置，所述干扰测量的参考信号用于IAB节点1的MT对IAB节点2的MT带来的干扰进行测量，其中，所述RS配置消息包括：IAB节点2的DU的参考信号资源标识例如：{3,4,5}，所述参考信号资源标识对应于IAB节点2的MT的波束。
S1402、第二节点的第二功能实体根据接收的RS配置消息，对用于干扰测量的参考信号进行配置。
如图15所示，所述IAB节点2的DU根据参考信号资源标识，选择对应的波束发送参考信号。
对于IAB节点2的MT，参考信号资源标识与传输信号具体使用的波束的对应关系是知道的，而在IAB节点2内部，DU可以与MT进行交互，从而DU也可以识别出SRI{3,4,5}对应的MT的波束具体为哪些，例如下图15阴影标识的3个物理波束。
例如:所述IAB节点2的MT使用参考信号资源标识{3,4,5}对应的波束集合{a,b,c}进行信号传输，当IAB节点1的MT对IAB节点2的MT进行干扰测量时，IAB节点2的DU与IAB节点2的MT进行交互，获得与所述参考信号资源标识{3,4,5}对应的IAB节点2的MT的波束集合{a,b,c}，IAB节点2的DU采用束集合{a,b,c}发送用于干扰测量的参考信号。
需要说明的是，所述IAB节点2的MT与DU的交互可以是硬件模块之间的交互，也可以是所述MT和DU进行集成时，通过软件实现上述交互。进一步地，所述RS配置消息中的参考信号资源指示信息还包括：下面一种或者多种组合：
IAB节点2的DU的参考信号映射的时频资源，IAB节点2的DU的参考信号发送功率，或者，IAB节点2的DU的参考信号的发送周期。
由于IAB节点2的DU是根据IAB节点2的MT的信息(发送波束及发送功率)对用于干扰测量的参考信号进行配置，通过IAB节点2的DU代替IAB节点2的MT发送所述参考信号，使得IAB节点1能够准确地检测到干扰测量的参考信号，从而对干扰进行测量，进而对干扰进行消除，极大地提升了IAB网络的性能。
S1404、第一节点发送干扰测量配置消息给第三节点的第一功能实体，所述干扰测量配置消息包括：所述第二节点的第二功能实体的参考信号资源指示信息和/或干扰测量类型指示信息，其中所述干扰测量类型指示信息用于指示第三节点的第一功能实体采用第三节点的第二功能实体的接收波束进行干扰测量。
所述第二节点的第二功能实体的参考信号资源指示信息的格式以及内容请参见步骤S800的具体描述。其中，干扰测量类型指示信息例如MTtoDU-Meas-Type，可以通过对上述S800中的所述第二节点的第二功能实体的参考信号资源指示信息的格式的扩展，将所述MTtoDU-Meas-Type新增到上述参考信号资源指示信息的格式的预留字段中，也可以将干扰测量类型指示信息例如MTtoDU-Meas-Type放置在RS配置消息的预留字段中。
第一节点向第三节点的第一功能实体发送的干扰测量配置消息可以基于RRC(Radio Resource Control,无线资源控制)协议，由第一节点向第三节点的第一功能实体发送，承载在RRC协议的特定消息中。也可以通过MAC CE来指示。
如图15所示，上述描述可以理解为：Donor节点向IAB节点1的MT发送的用于干扰测量的配置可以基于RRC(Radio Resource Control,无线资源控制)协议由Donor向IAB节点1的MT发送，承载在RRC协议的特定消息中。也可以通过MAC CE来指示。
S1406、第二节点的第二功能实体发送用于干扰测量的参考信号。
如图15所示，IAB节点2的DU采用RS配置消息中的参考信号资源标识对应的一个或者多个波束发送干扰测量的参考信号，便于IAB节点1的MT进行干扰测量。
进一步地，IAB节点2的DU还可以在指定的时频资源上发送用于干扰测量的参考信 号，如果需要进行周期性地测量，IAB节点2的DU还会在指定的发送周期内，周期性发送该参考信号，以及使用指定的发送功率发送上述参考信号。
所述参考信号可以包括如下一种或者几种：同步信号SSB,信道状态信息参考信号CSI-RS,解调参考信号DMRS,跟踪参考信号TRS,相位跟踪参考信号PTRS,探测参考信号SRS,或其他RS。
S1408、第三节点的第一功能实体根据所述干扰测量配置中的干扰测量类型指示，检测第二节点的第二功能实体发送的用于干扰测量的参考信号，进行干扰测量。
如图15所示，IAB节点1的MT根据干扰测量类型指示，使用IAB节点1的DU的接收波束检测所述IAB节点2的DU发送的参考信号，进行干扰测量。
进一步地，IAB节点1的MT还可以根据在干扰配置中指示的时频资源以及周期内对IAB节点2的DU发送的用于干扰测量的参考信号进行检测。
实施例七：
本发明实施例还提供另一种实施例的方法流程图，如图16所示。
以图17的IAB的组网架构图为例进行举例说明，但是不限制于图17，可以应用到上面的各种组网架构图中。
图17中，IAB节点1通过DU在接收其下级节点或终端发送的信号，IAB节点2通过MT发送数据给Donor节点。这时IAB节点1的DU在接收上行信号时，受到IAB节点2的MT发送的上行信号的干扰，这里的干扰源是IAB节点2，受干扰节点是IAB节点1，所述干扰具体可以是交叉链路干扰CLI，所述CLI是IAB节点2的MT对IAB节点1的DU产生的干扰。
如图17所示，IAB节点1和IAB节点2在部分时隙上可能存在DU与MT之间的交叉链路干扰，因此需要完成IAB节点1的DU与IAB节点2的MT之间的交叉链路干扰的测量，具体干扰测量方法如下：
S1600、第一节点发送干扰测量指示消息，所述干扰测量指示消息用于指示第二节点的第二功能实体上报用于干扰测量的参考信号配置消息。
如图17，Donor节点向IAB节点2的DU发送干扰测量指示消息，指示IAB节点2的DU生成用于干扰测量的参考信号配置信息，并进行上报。
其中，所述干扰测量指示消息可以承载在无线资源控制(Radio Resource Control,RRC)协议消息中，或者，通过F1接口承载在基于F1-AP(F1-application protocol)协议的消息中，例如：下行无线资源控制转移消息(DL RRC TRANSFER message)，所述F1接口为IAB节点2的分布单元(distributed unit,DU)与Donor节点的集中单元(central unit,CU)之间的F1接口。
所述干扰测量指示消息还可以是由Donor节点通过RRC、DCI或MAC CE发送给IAB节点2的MT，再由IAB节点2的MT通过内部的信令交互通知IAB节点2的DU，使得IAB节点2的DU生成用于干扰测量的参考信号配置信息，并进行上报。
干扰测量指示消息的具体实现方式有如下几种：
方式一：通过1个比特进行指示，触发第二节点的第二功能实体生成用于干扰测量的参考信号配置信息，并进行上报，例如：用CLI-Meas-Indicator：0或者1来表示。
方式二：所述干扰测量指示消息包括下面一种或者几种组合：第二节点的第二功能实 体发送的用于干扰测量的参考信号的发送时隙或者发送周期，通过上述消息，触发第二节点的第二功能实体生成用于干扰测量的参考信号配置信息，并进行上报。例如，通过下面的指示消息的消息格式实现：
CLI-Meas-Indicator::＝SEQUENCE{
sfnForCliMeas OPTIONAL
periodicityAndOffset
...
sfnForCliMeas指示了所述用于干扰测量对的参考信号的发送时隙，periodicityAndOffset指示了所述用于干扰测量对的参考信号的发送周期，和/或每个周期内的时隙偏移量。
方式三：方式一与方式二的组合进行实现。具体为：通过方式一触发第二节点的第二功能实体生成用于干扰测量的参考信号配置信息，然后再通过方式二指示第二节点的第二功能实体发送的用于干扰测量的参考信号的发送时隙或者发送周期。
S1602、第二节点的第二功能实体上报用于干扰测量的参考信号配置消息，所述参考信号配置消息包括：第二节点的第二功能实体的参考信号资源指示信息，所述第二功能实体的参考信号资源指示信息包括：第二节点的第二功能实体的参考信号资源标识。
具体为，第二节点的第二功能实体生成所述第二功能实体的参考信号资源指示信息，所述第二功能实体的参考信号资源指示信息包括：第二节点的第二功能实体的参考信号资源标识。
上述第二节点的第二功能实体的参考信号资源标识是第二节点的第二功能实体根据所述第二节点的第一功能实体的发送波束获得的。
进一步地，当第二节点的第二功能实体自身配置所述参考信号的发送功率时，将所述第二节点的第一功能实体的发送功率作为所述第二节点的第二功能实体的参考信号的发送功率，同时自身配置所述的参考信号使用的时频资源以及所述参考信号的发送周期。所述第二节点的第二功能实体将所述发送功率，所述时频资源以及所述发送周期包含在所述参考信号资源指示信息中，通过用于干扰测量的参考信号配置消息上报给第一节点。
如图17所示，具体的参考信号资源指示信息格式如下：
定义一种新的参考信号资源指示信息，具体指示信息的格式示例如下：
Figure PCTCN2019108123-appb-000009
其中，RS-Resource为参考信号资源指示信息；
RS-ResourceId为参考信号资源标识。
可选地，所述参考信号资源指示信息还可以包括下面一种或者几种：
resourceMapping：参考信号映射的时频资源位置；
powercontrol：所述参考信号的功率控制，指示了IAB节点2的DU发送参考信号使 用的发射功率。其中，所述参考信号的发射功率配置为IAB节点2的MT的发射功率。

当前面涉及的所述发送功率以及所述时频资源是由第一节点配置时，可以参考图4a,4b以及图5所提供的参考信号配置消息下发给第二节点的第二功能实体，也可以是通过其它消息将所述发送功率以及所述时频资源发送给第二节点的第二功能实体。
具体的：所述第二节点的第一功能实体的发送波束以及第二节点的第一功能实体的发送功率的获得过程如下：
如图17所示，IAB节点2的DU通过与自身的MT进行信息交互，获得自身的MT的发送波速，以及发送功率，IAB节点2的DU根据所述获得的MT的发送波速生成参考信号资源标识。
这里的发送波束信息可能是MT最近一次发送SRS所使用的波束或波束集合，也可能是IAB节点2的MT最近一次收到的Donor配置的SRI所对应的波束或波束集合，并且这些波束各自都对应了一个SRI。
IAB节点2的DU将使用IAB节点2的MT的发送波束以及发送功率发送用于干扰测量的参考信号。
IAB节点2的DU生成的用于干扰测量的参考信号配置消息中包括一个或多个参考信号资源指示信息，每个参考信号资源指示信息对应一个发送波束。例如，如果MT通知给DU的波束个数有16个，则DU将产生16个参考资源指示信息，包含在参考信号配置消息。
另外，所述IAB节点2的DU生成并发送给Donor节点的用于干扰测量的参考信号配置消息可以承载在无线资源控制(Radio Resource Control,RRC)协议消息中，或者，通过F1接口承载在基于F1-AP(F1-application protocol)协议的消息中，所述F1接口为IAB节点2的分布单元(distributed unit,DU)与Donor节点的集中单元(central unit,CU)之间的F1接口。
S1604、第一节点发送干扰测量配置消息给第三节点的第一功能实体，所述干扰测量配置消息包括：所述第二节点的第二功能实体的参考信号资源指示信息和/或干扰测量类型指示信息，其中所述干扰测量类型指示信息用于指示第三节点的第一功能实体采用第三节点的第二功能实体的接收波束进行干扰测量。
所述第二节点的第二功能实体的参考信号资源指示信息的格式以及内容请参见步骤S800的具体描述。其中，干扰测量类型指示信息例如MTtoDU-Meas-Type，可以通过对上述S800中的所述第二节点的第二功能实体的参考信号资源指示信息的格式的扩展，将所述MTtoDU-Meas-Type新增到上述参考信号资源指示信息的格式的预留字段中，也可以将干扰测量类型指示信息例如MTtoDU-Meas-Type放置在RS配置消息的预留字段中。
第一节点向第三节点的第一功能实体发送的干扰测量配置消息可以基于RRC(Radio Resource Control,无线资源控制)协议，由第一节点向第三节点的第一功能实体发送，承载在RRC协议的特定消息中。也可以通过MAC CE来指示。
如图17所示，上述描述可以理解为：Donor节点向IAB节点1的MT发送的用于干扰测量的配置可以基于RRC(Radio Resource Control,无线资源控制)协议由Donor向IAB节 点1的MT发送，承载在RRC协议的特定消息中。也可以通过MAC CE来指示。
S1606、第二节点的第二功能实体根据用于干扰测量的参考信号配置消息，发送用于干扰测量的参考信号。
如图17所示，IAB节点2的DU获得自身的MT的发送波束，在这些波束上发送所述参考信号。
进一步地，IAB节点2的DU在自身配置或者指定的时频资源上发送用于干扰测量的参考信号，如果需要进行周期性地测量，还会在自身配置或者指定的发送周期内，周期性发送该参考信号，以及使用指定的或者自身配置的发送功率发送上述参考信号。
所述参考信号可以包括如下一种或者几种：同步信号SSB,信道状态信息参考信号CSI-RS,解调参考信号DMRS,跟踪参考信号TRS,相位跟踪参考信号PTRS,探测参考信号SRS,或其他RS。
S1608、第三节点的第一功能实体根据所述干扰测量配置中的干扰测量类型指示，检测第二节点的第二功能实体发送的用于干扰测量的参考信号，进行干扰测量。
如图17所示，IAB节点1的MT根据干扰测量类型指示，使用IAB节点1的DU的接收波束检测所述IAB节点2的DU发送的参考信号，进行干扰测量。
进一步地，IAB节点1的MT还可以根据在干扰配置中指示的时频资源以及周期内对IAB节点2的DU发送的用于干扰测量的参考信号进行检测。
