技术领域
本申请涉及通信技术领域，尤其涉及一种干扰测量方法及装置。
背景技术
在通信系统中，为了提升基站的覆盖范围引入了中继(relay)传输：在基站与用户设备之间增加了一个或多个中继节点(relay node，RN)，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达用户设备。在中继系统中存在三类网元：基站、中继节点及用户设备，三类网元之间的连接关系可如图1所示。其中，基站和中继节点间的链路称为回传链路(backhaul link，BL)，中继节点和用户设备间的链路称为接入链路(access link，AL)。
在中继通信系统中，由于存在两个链路(回传链路和接入链路)的数据传输，因而两个链路间的干扰会导致系统性能降低。
因此，如何测量两个链路间的干扰成为一个亟需解决的问题。

具体实施方式
在通信系统中，由于高频通信的引入，由遮挡引起的覆盖范围问题和覆盖空洞问题成为了无线通信系统设计的挑战。为了提升基站等网络设备的覆盖范围，引入了中继(realy)传输。
在中继系统中，为了减小回传链路和接入链路之间的干扰，首先需要测量两个链路间的干扰，从而根据两个链路间的干扰情况改变中继系统中各个网元的配置，从而减小两个链路间的干扰。
下面对本申请实施例的应用场景加以介绍。
如图1所示，本申请实施例中，中继系统中存在三类网元：基站、中继节点及用户设备。当然，图1所示的中继系统是以无线信号经过两跳到达用户设备的场景为例，具体实现时还存在无线信号经过两跳以上到达用户设备的场景，此时，图1中的用户设备可以替换为另一个中继节点。
为了使本申请更容易被理解，下面首先对本申请实施例涉及的一些基本概念进行解释。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。

为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
本申请提供一种干扰测量方法及装置，用以测量中继系统中回传链路和接入链路之间的干扰。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
需要说的是，本申请中所涉及的多个是指两个或两个以上；在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
下面将分别通过三个实施例对本申请提供的干扰测量方法加以说明。
实施例一
参见图2，为本申请实施例提供的一种干扰测量方法。该方法包括如下步骤：
S201：基站向中继节点发送第一配置信息，相应地，中继节点接收基站发送的第一配置信息。
S201中，第一配置信息为中继节点向用户设备发送的N个参考信号的配置信息，N≥1。
其中，N个参考信号的配置信息包括以下信息中的至少一种：N个参考信号的发送时间；N个参考信号的载波频率；N个参考信号的序列；N个参考信号的子载波间隔；N个参考信号的端口信息；N个参考信号的参考信号索引。
在图2所示的干扰测量方法中，基站可以是前述的第一设备，中继节点可以是前述的第二设备，用户设备可以是前述的第三设备。当然，前述第一设备也可以是中继系统中除第二设备以外的另一个中继节点，前述第三设备也可以是中继系统中除第二设备以外的另一个中继节点，本申请实施例中对此不做限定。
需要说明的是，S201中，基站可以主动向中继节点发送第一配置信息，也可以基于中继节点的请求向中继节点发送第一配置信息，本申请实施例中对此不做限定。此外，由于中继节点在向用户设备发送参考信号时可以基于不同的numerology发送，因而基站向中继节点发送的第一配置信息中还可指示中继节点在向用户设备发送参考信号时基于哪个numerology进行发送。
可选地，在S201中基站向中继节点发送第一配置信息后中继节点可根据第一配置信息向用户设备发送N个参考信号，那么，基站可根据第一配置信息对N个参考信号进行测量，从而根据测量结果确定中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
具体地，中继节点向用户设备发送的N个参考信号可以采用不同的赋形波束发送。例如，中继节点可采用N个赋形波束分别向用户设备发送N个参考信号，此时，第一配置信息即可用于指示中继节点在发送参考信号时采用的是哪个赋形波束。那么，基站可根据第一配置信息测量N个赋形波束下中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
在基站对N个参考信号进行干扰测量之后，基站需要根据测量结果来指示中继节点在后续向用户设备发送信号时基于何种配置进行发送，以减小接入链路对回传链路的干扰。该指示方式可以有多种，下面列举其中两种方式。
方式一
在基站对N个参考信号进行干扰测量之后，基站可向中继节点发送第三配置信息，第三配置信息为N个参考信号中的至少一个参考信号的配置信息，从而使得中继节点可根据第三配置信息向用户设备发送信号，以减小接入链路对回传链路的干扰。
其中，至少一个参考信号的配置信息包括以下信息中的至少一种：至少一个参考信号的发送时间；至少一个参考信号的载波频率；至少一个参考信号的序列；至少一个参考信号的子载波间隔；至少一个参考信号的端口信息；至少一个参考信号的参考信号索引。
在方式一中，基站在对N个参考信号进行干扰测量以后，基站可以根据测量结果筛选出N个参考信号中的至少一个参考信号，并将该至少一个参考信号的配置信息发送给中继节点。这里所说的测量结果可以包含如下信息中的至少一种：N个参考信号的参考信号接收功率(reference signal receiving power，RSRP)、N个参考信号的信道质量指示(channel quality indicator，CQI)、N个参考信号的信号干扰比(signal-to-interference rate，SIR)、N个参考信号的信号与干扰加噪声比(signal to interference plus noise ratio，SINR)。也就是说，在中继节点向用户设备发送参考信号时，基站可以测量该参考信号的RSRP、CQI、SIR或SINR等参数中的一种或几种，然后根据测量结果确定该参考信号所在的接入链路对回传链路的干扰；当基站完成对N个参考信号的测量后，即可根据N个参考信号的测量结果筛选出至少一个参考信号，将该至少一个参考信号的配置信息(第三配置信息)发送给中继节点。
其中，基站筛选出的至少一个参考信号可以是接入链路对回传链路干扰较小时中继节点对应发送的参考信号。特别地，当中继节点采用N个赋形波束分别向用户设备发送N个参考信号时，基站选择的至少一个参考信号与至少一个赋形波束一一对应，也就是说，基站向中继节点发送的第三配置信息指示了中继节点在采用上述至少一个赋形波束向用户设备发送至少一个参考信号时，接入链路对回传链路的干扰较小。那么，中继节点在接收到第三配置信息后即可获知：在后续向用户设备发送信号时，可采用上述至少一个赋形波束发送，从而减小接入链路对回传链路的干扰。
需要说明的是，本申请实施例中，第一配置信息和第三配置信息包括的信息类型可以不同。例如，第一配置信息可以包含N个参考信号的发送时间和载波频率，第三 配置信息可以包含至少一个参考信号的端口信息和参考信号索引；或者，第一配置信息可以包含N个参考信号的序列和载波频率，第三配置信息可以包含至少一个参考信号的子载波间隔和载波频率。
方式二
在基站对N个参考信号进行干扰测量之后，基站可向中继节点发送N个参考信号中的至少一个参考信号的测量结果；相应地，中继节点接收基站发送的N个参考信号中的至少一个参考信号的测量结果，从而使得中继节点根据至少一个参考信号的测量结果确定在后续向用户设备发送信号的过程中基于何种配置进行发送。
其中，至少一个参考信号的测量结果包含以下至少一种：至少一个参考信号的标识或配置信息；至少一个参考信号的RSRP；至少一个参考信号的CQI；至少一个参考信号的SIR；至少一个参考信号的SINR。
需要说明的是，在方式二中，至少一个参考信号的测量结果中不仅可以包含至少一个参考信号的参数，例如RSRP、CQI、SIR和SINR，还可以包括至少一个参考信号的标识和配置信息，这是因为：如果基站仅向中继节点发送至少一个参考信号的RSRP、CQI、SIR和SINR等参数中的一个或多个，中继节点难以辨识出这至少一个参考信号是中继节点向用户设备发送的N个参考信号中的哪些参考信号。因此，基站可在测量结果中发送该至少一个参考信号的标识和配置信息，从而用于中继节点辨识该至少一个参考信号。其中，至少一个参考信号的配置信息包括以下信息中的至少一种：至少一个参考信号的发送时间；至少一个参考信号的载波频率；至少一个参考信号的序列；至少一个参考信号的子载波间隔；至少一个参考信号的端口信息；至少一个参考信号的参考信号索引。
方式二与方式一的不同之处在于：方式一中，至少一个参考信号是基站根据N个参考信号的测量结果筛选出的，且基站向中继节点发送的是至少一个参考信号的配置信息(即第三配置信息)，中继节点在后续向用户设备发送信号时可基于至少一个参考信号的配置信息(即第三配置信息)进行发送；而方式二中的至少一个参考信号可以是基站根据测量结果从N个参考信号中初步筛选出的，也可以是没有经过筛选的N个参考信号，且基站向中继节点发送的是至少一个参考信号的测量结果，中继节点在接收到至少一个参考信号的测量结果后，可进一步对至少一个参考信号进行筛选，在后续向用户设备发送信号时可基于至少一个参考信号中的全部或部分参考信号的配置信息进行发送。
此外，在图2所示的干扰测量方法中，为了使得测量结果更为准确，中继节点每次向用户设备发送参考信号的同时，也可在同一个时频资源上向基站发送参考信号，为了便于区分，本申请实施例中将中继节点发送给基站的参考信号称为“第二参考信号”。当中继节点在同一个时频资源上向用户设备和基站发送参考信号时，接入链路和回传链路中同时存在数据传输，因而这种情况下的测量结果会更为准确。特别地，在上述过程中，中继节点向基站发送的第二参考信号可以是零功率参考信号(zero power reference signal，ZP RS)。也就是说，中继节点在同一个时频资源上向用户设备发送用于干扰测量的参考信号并向基站发送ZP RS，此时，由于接入链路和回传链路均占用该时频资源，因而在该时频资源上的参考信号传输不会受到其他信号的干扰，基站在该时频资源上对参考信号进行测量，测量结果更为准确。
在图2所示的干扰测量方法中，由于基站向中继节点发送了第一配置信息，而第一配置信息是中继节点向用户设备发送的N个参考信号的配置信息，也就是说，中继节点可以根据第一配置信息向用户设备发送N个参考信号。由于第一配置信息对于基站来说是已知的，因而基站可以基于第一配置信息对中继节点向用户设备发送的N个参考信号进行干扰测量，从而基站可以获知中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
基于以上对实施例一的描述，本申请实施例还提供一种干扰测量方法，该干扰测量方法可视为图2所示方法的一个具体示例，该方法和图2所示方法可相互参见。参见图3，该方法包括如下步骤：
S301:中继节点向基站发送请求消息，请求基站配置中继节点向用户设备发送参考信号时所使用的时频资源。
其中，中继节点向用户设备发送参考信号时所使用的时频资源可视为图2所示方法中第一配置信息的一个具体示例。
如前所述，第一配置信息为中继节点向用户设备发送的N个参考信号的配置信息。N个参考信号的配置信息包括以下信息中的至少一种：N个参考信号的发送时间；N个参考信号的载波频率；N个参考信号的序列；N个参考信号的子载波间隔；N个参考信号的端口信息；N个参考信号的参考信号索引。那么，在图3所示方法中，中继节点向用户设备发送参考信号时所使用的时频资源可视为N个参考信号的发送时间和N个参考信号的载波频率。
S302：基站向中继节点发送响应消息，以配置中继节点向用户设备发送参考信号时所使用的时频资源。
此外，S302中，基站还可配置中继节点在上述时频资源上向基站发送N个ZP RS。其中，ZP RS为图2所示方法中第二参考信号的一个具体示例。由于ZP RS的功率为零，因而中继节点实际上并没有向基站发送参考信号，而只是占用了基站和中继节点之间的时频资源。这样做的好处是：中继节点在同一个时频资源上向用户设备发送用于干扰测量的N个参考信号并向基站发送N个ZP RS，此时，该时频资源上发送的参考信号不会受到其他信号的干扰，基站可在该时频资源上对参考信号进行测量，从而准确地确定接入链路对回传链路的干扰。
S302中，基站向中继节点发送的响应消息可以是高层信令或下行控制消息(downlink control information，DCI)。其中，高层信令包括但不限于：无线资源控制(radio resource control，RRC)消息、媒体介入控制层控制元素(media access control control element，MAC CE)、广播消息、系统消息等。
S303：中继节点在上述时频资源上采用N个赋形波束中的一个赋形波束向用户设备发送参考信号。
S304：基站测量该赋形波束下接入链路对回传链路的干扰。
具体地，基站可在ZP RS所占用的时频资源上测量参考信号的RSRP、CQI、SIR和SIN等参数，从而确定该赋形波束下接入链路对回传链路的干扰。
将S303～S304执行N次：即每次执行S303时中继节点均采用不同的赋形波束向用户设备发送参数信号，每次执行S304时基站测量每个赋形波束下接入链路对回传链路的干扰。那么，通过将S303～S304执行N次，基站可确定N个赋形波束下接入链路 对回传链路的干扰。
S305：基站向中继节点发送通知消息，以通知中继节点在向用户设备发送信号时可以使用的赋形波束集合。
S305中，中继节点在向用户设备发送信号时可以采用的赋形波束集合中包含的赋形波束为前述N个赋形波束中的至少一个赋形波束。
S305中，基站通过通知消息向中继节点指示的赋形波束集合可视为图2所示方法中的第三配置信息的一个具体示例。图2所示方法中，第三配置信息为基站根据测量结果筛选出的、N个参考信号中的至少一个参考信号的配置信息，而图3所示方法中，赋形波束集合为基站筛选出的、N个赋形波束中的至少一个赋形波束；由于图3所示方法中，N个赋形波束和N个参考信号是一一对应的，因而基站通过通知消息指示中继节点采用N个赋形波束中的至少一个赋形波束向用户设备发送信号，即相当于图2所示方法中基站向中继节点发送N个参考信号中的至少一个参考信号的配置信息(即第三配置信息)。
S305中，基站向中继节点发送的通知消息可以是高层信令或DCI。其中，高层信令包括但不限于：RRC消息、MAC CE、广播消息、系统消息等。
此外，在图3所示方法中，中继节点和基站间进行信号传输所使用的赋形波束不同时，基站在S305中向中继节点发送的赋形波束集合中包含的赋形波束可以相同，也可以不同。例如，当中继节点在S301中采用赋形波束A向基站发送请求消息、基站在S302中采用赋形波束B向中继节点发送响应消息时，S305中基站向中继节点发送的赋形波束集合中包含赋形波束1、赋形波束2和赋形波束3；那么，当中继节点在S301中采用赋形波束C向基站发送请求消息、基站在S302中采用赋形波束D向中继节点发送响应消息时，S305中基站向中继节点发送的赋形波束集合中包含的赋形波束可以是赋形波束1、赋形波束2和赋形波束3，也可以是赋形波束4、赋形波束5和赋形波束6。
通过图3所示方法，基站可以配置中继节点向用户设备发送信号时所使用的赋形波束集合，从而减小接入链路对回传链路的干扰。
实施例二
参见图4，为本申请实施例提供的一种干扰测量方法。该方法包括如下步骤：
S401：中继节点向基站发送第二配置信息，相应地，基站接收中继节点发送的第二配置信息。
S401中，第二配置信息为中继节点向用户设备发送的N个参考信号的配置信息，N≥1。
其中，N个参考信号的配置信息包括以下信息中的至少一种：N个参考信号的发送时间；N个参考信号的载波频率；N个参考信号的序列；N个参考信号的子载波间隔；N个参考信号的端口信息；N个参考信号的参考信号索引。
在图2所示的干扰测量方法中，基站可以是前述的第一设备，中继节点可以是前述的第二设备，用户设备可以是前述的第三设备。当然，前述第一设备也可以是中继系统中除第二设备以外的另一个中继节点，前述第三设备也可以是中继系统中除第二设备以外的另一个中继节点，本申请实施例中对此不做限定。
需要说明的是，由于中继节点在向用户设备发送参考信号时可以基于不同的numerology发送，因而第二配置信息中还可指示中继节点在向用户设备发送参考信号时基于哪个numerology进行发送。
实施例二与实施例一的不同指出在于：实施例一中，N个参考信号的配置信息(第一配置信息)是由基站确定后发送给中继节点的，中继节点可基于基站发送的第一配置信息向用户设备发送N个参考信号，基站可根据自身确定的第一配置信息进行干扰测量；而实施例二中，N个参考信号的配置信息(即第二配置信息)是由中继节点确定后发送给基站的，中继节点可基于自身确定的第二配置信息向用户设备发送N个参考信号，而基站也可以基于从中继节点接收到的第二配置信息进行干扰测量。
可选地，在S401中中继节点向基站发送第二配置信息后中继节点可根据第二配置信息向用户设备发送N个参考信号，那么，基站可根据第二配置信息对N个参考信号进行测量，从而根据测量结果确定中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
具体地，中继节点向用户设备发送的N个参考信号可以是采用不同的赋形波束发送的。例如，中继节点可采用N个赋形波束分别向用户设备发送N个参考信号，此时，第二配置信息即可用于指示中继节点在发送参考信号时采用的是哪个赋形波束。那么，基站可根据第二配置信息测量N个赋形波束下中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
在基站对N个参考信号进行干扰测量之后，基站需要根据测量结果来指示中继节点在后续向用户设备发送信号时基于何种配置进行发送，以减小接入链路对回传链路的干扰。该指示方式可以有多种，下面列举其中两种方式。
方式一
在基站对N个参考信号进行干扰测量之后，基站可向中继节点发送第三配置信息，第三配置信息为N个参考信号中的至少一个参考信号的配置信息，从而使得中继节点可根据第三配置信息向用户设备发送信号，以减小接入链路对回传链路的干扰。
其中，至少一个参考信号的配置信息包括以下信息中的至少一种：至少一个参考信号的发送时间；至少一个参考信号的载波频率；至少一个参考信号的序列；至少一个参考信号的子载波间隔；至少一个参考信号的端口信息；至少一个参考信号的参考信号索引。
在方式一中，基站在对N个参考信号进行干扰测量以后，基站可以根据测量结果筛选出N个参考信号中的至少一个参考信号，并将该至少一个参考信号的配置信息发送给中继节点。这里所说的测量结果可以包含如下信息中的至少一种：N个参考信号的RSRP、N个参考信号的CQI、N个参考信号的SIR、N个参考信号的SINR。也就是说，在中继节点向用户设备发送参考信号时，基站可以测量该参考信号的RSRP、CQI、SIR或SINR等参数中的一种或几种，然后根据测量结果确定该参考信号所在的接入链路对回传链路的干扰；当基站完成对N个参考信号的测量后，即可根据N个参考信号的测量结果筛选出至少一个参考信号，将该至少一个参考信号的配置信息(第三配置信息)发送给中继节点。
其中，基站筛选出的至少一个参考信号可以是接入链路对回传链路干扰较小时中继节点对应发送的参考信号。特别地，当中继节点采用N个赋形波束分别向用户设备 发送N个参考信号时，基站选择的至少一个参考信号与至少一个赋形波束一一对应，也就是说，基站向中继节点发送的第三配置信息指示了中继节点在采用上述至少一个赋形波束向用户设备发送至少一个参考信号时，接入链路对回传链路的干扰较小。那么，中继节点在接收到第三配置信息后即可获知：在后续向用户设备发送信号时，可采用上述至少一个赋形波束发送，从而减小接入链路对回传链路的干扰。
需要说明的是，本申请实施例中，第二配置信息和第三配置信息包括的信息类型可以不同。例如，第二配置信息可以包含N个参考信号的发送时间和载波频率，第三配置信息可以包含至少一个参考信号的端口信息和参考信号索引；或者，第二配置信息可以包含N个参考信号的序列和载波频率，第三配置信息可以包含至少一个参考信号的子载波间隔和载波频率。
方式二
在基站对N个参考信号进行干扰测量之后，基站可向中继节点发送N个参考信号中的至少一个参考信号的测量结果；相应地，中继节点接收基站发送的N个参考信号中的至少一个参考信号的测量结果，从而使得中继节点根据至少一个参考信号的测量结果确定在后续向用户设备发送信号的过程中基于何种配置进行发送。
其中，至少一个参考信号的测量结果包含以下至少一种：至少一个参考信号的标识或配置信息；至少一个参考信号的RSRP；至少一个参考信号的CQI；至少一个参考信号的SIR；至少一个参考信号的SINR。
需要说明的是，在方式二中，至少一个参考信号的测量结果中不仅可以包含至少一个参考信号的参数，例如RSRP、CQI、SIR和SINR，还可以包括至少一个参考信号的标识和配置信息，这是因为：如果基站仅向中继节点发送至少一个参考信号的RSRP、CQI、SIR和SINR等参数中的一个或多个，中继节点难以辨识出这至少一个参考信号是中继节点向用户设备发送的N个参考信号中的哪些参考信号。因此，基站可在测量结果中发送该至少一个参考信号的标识和配置信息，从而用于中继节点辨识该至少一个参考信号。其中，至少一个参考信号的配置信息包括以下信息中的至少一种：至少一个参考信号的发送时间；至少一个参考信号的载波频率；至少一个参考信号的序列；至少一个参考信号的子载波间隔；至少一个参考信号的端口信息；至少一个参考信号的参考信号索引。
方式二与方式一的不同之处在于：方式一中，至少一个参考信号是基站根据N个参考信号的测量结果筛选出的，且基站向中继节点发送的是至少一个参考信号的配置信息(即第三配置信息)，中继节点在后续向用户设备发送信号时可基于至少一个参考信号的配置信息(即第三配置信息)进行发送；而方式二中的至少一个参考信号可以是基站根据测量结果从N个参考信号中初步筛选出的，也可以是没有经过筛选的N个参考信号，且基站向中继节点发送的是至少一个参考信号的测量结果，中继节点在接收到至少一个参考信号的测量结果后，可进一步对至少一个参考信号进行筛选，在后续向用户设备发送信号时可基于至少一个参考信号中的全部或部分参考信号的配置信息进行发送。
此外，在图4所示的干扰测量方法中，为了使得测量结果更为准确，中继节点每次向用户设备发送参考信号的同时，也可在同一个时频资源上向基站发送参考信号，为了便于区分，本申请实施例中将中继节点发送给基站的参考信号称为“第二参考信 号”。当中继节点在同一个时频资源上向用户设备和基站发送参考信号时，接入链路和回传链路中同时存在数据传输，因而这种情况下的测量结果会更为准确。特别地，在上述过程中，中继节点向基站发送的第二参考信号可以是ZP RS。也就是说，中继节点在同一个时频资源上向用户设备发送用于干扰测量的参考信号并向基站发送ZP RS，此时，由于接入链路和回传链路均占用该时频资源，因而在该时频资源上的参考信号传输不会受到其他信号的干扰，基站在该时频资源上对参考信号进行测量，测量结果更为准确。
在图4所示的干扰测量方法中，由于中继节点向基站发送了第二配置信息，而第二配置信息是中继节点向用户设备发送的N个参考信号的配置信息，也就是说，中继节点可以根据第二配置信息向用户设备发送N个参考信号，基站也可以基于第二配置信息对中继节点向用户设备发送的N个参考信号进行干扰测量，从而基站可以获知中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
基于以上对实施例二的描述，本申请实施例还提供一种干扰测量方法，该干扰测量方法可视为图4所示方法的一个具体示例，该方法和图4所示方法可相互参见。参见图5，该方法包括如下步骤：
S501:中继节点向基站发送第一消息，用于指示中继节点向用户设备发送参考信号时所述使用的时频资源。
其中，中继节点向用户设备发送参考信号时所使用的时频资源可视为图4所示方法中第二配置信息的一个具体示例。
如前所述，第二配置信息为中继节点向用户设备发送的N个参考信号的配置信息。N个参考信号的配置信息包括以下信息中的至少一种：N个参考信号的发送时间；N个参考信号的载波频率；N个参考信号的序列；N个参考信号的子载波间隔；N个参考信号的端口信息；N个参考信号的参考信号索引。那么，在图5所示方法中，中继节点向用户设备发送参考信号时所使用的时频资源可视为N个参考信号的发送时间和N个参考信号的载波频率。
S502：中继节点在上述时频资源上采用N个赋形波束中的一个赋形波束向用户设备发送参考信号。
此外，S502中，中继节点还可在上述时频资源上向基站发送N个ZP RS。其中，ZP RS为图4所示方法中第二参考信号的一个具体示例。由于ZP RS的功率为零，因而中继节点实际上并没有向基站发送参考信号，而只是占用了基站和中继节点之间的时频资源。这样做的好处是：中继节点在同一个时频资源上向用户设备发送用于干扰测量的N个参考信号并向基站发送N个ZP RS，此时，该时频资源上发送的参考信号不会受到其他信号的干扰，基站可在该时频资源上对参考信号进行测量，从而准确地确定接入链路对回传链路的干扰。
S503：基站测量该赋形波束下接入链路对回传链路的干扰。
具体地，基站可在ZP RS所占用的时频资源上测量参考信号的RSRP、CQI、SIR和SIN等参数，从而确定该赋形波束下接入链路对回传链路的干扰。
将S502～S503执行N次：即每次执行S502时中继节点均采用不同的赋形波束向用户设备发送参数信号，每次执行S503时基站测量每个赋形波束下接入链路对回传链 路的干扰。那么，通过将S502～S503执行N次，基站可确定N个赋形波束下接入链路对回传链路的干扰。
S504：基站向中继节点发送通知消息，以通知中继节点在向用户设备发送信号时可以使用的赋形波束集合。
S504中，中继节点在向用户设备发送信号时可以采用的赋形波束集合中包含的赋形波束为前述N个赋形波束中的至少一个赋形波束。
S504中，基站通过通知消息向中继节点指示的赋形波束集合可视为图4所示方法中的第三配置信息的一个具体示例。图4所示方法中，第三配置信息为基站根据测量结果筛选出的、N个参考信号中的至少一个参考信号的配置信息，而图5所示方法中，赋形波束集合为基站筛选出的、N个赋形波束中的至少一个赋形波束；由于图5所示方法中，N个赋形波束和N个参考信号是一一对应的，因而基站通过通知消息指示中继节点采用N个赋形波束中的至少一个赋形波束向用户设备发送信号，即相当于图4所示方法中基站向中继节点发送N个参考信号中的至少一个参考信号的配置信息(即第三配置信息)。
S504中，基站向中继节点发送的通知消息可以是高层信令或DCI。其中，高层信令包括但不限于：RRC消息、MAC CE、广播消息、系统消息等。
此外，在图5所示方法中，中继节点和基站间进行信号传输所使用的赋形波束不同时，基站在S504中向中继节点发送的赋形波束集合中包含的赋形波束可以相同，也可以不同。例如，当中继节点在S501中采用赋形波束A向基站发送第一消息时，S504中基站向中继节点发送的赋形波束集合中包含赋形波束1、赋形波束2和赋形波束3；那么，当中继节点在S501中采用赋形波束C向基站发送第一消息时，S504中基站向中继节点发送的赋形波束集合中包含的赋形波束可以是赋形波束1、赋形波束2和赋形波束3，也可以是赋形波束4、赋形波束5和赋形波束6。
通过图5所示方法，基站可以配置中继节点向用户设备发送信号时所使用的赋形波束集合，从而减小接入链路对回传链路的干扰。
实施例三
参见图6，为本申请实施例提供的一种干扰测量方法。该方法包括如下步骤：
S601：中继节点向基站发送测量结果；相应地，基站接收中继节点发送的测量结果。
其中，测量结果为用户设备向中继节点发送的N个参考信号中的至少一个参考信号的测量结果，N≥1。
在图6所示的干扰测量方法中，基站可以是前述的第一设备，中继节点可以是前述的第二设备，用户设备可以是前述的第三设备。当然，前述第一设备也可以是中继系统中除第二设备以外的另一个中继节点，前述第三设备也可以是中继系统中除第二设备以外的另一个中继节点，本申请实施例中对此不做限定。
S601中，中继节点向基站发送测量结果时，可采用不同的上报方式：中继节点可以逐个上报至少一个参考信号的测量结果，或者中继节点可以将至少一个参考信号的测量结果统一上报；此外，中继节点在上报至少一个参考信号的测量结果的同时，还可上报至少一个参考信号的测量结果的排序情况。
具体地，S601中，至少一个参考信号的测量结果可包含以下至少一种：至少一个参考信号的标识或配置信息；至少一个参考信号的RSRP；至少一个参考信号的CQI；至少一个参考信号的SIR；至少一个参考信号的SINR。也就是说，在用户设备向中继节点发送参考信号时，中继节点可以测量该参考信号的RSRP、CQI、SIR或SINR等参数中的一种或几种，然后根据测量结果确定该参考信号所在的接入链路对回传链路的干扰；当中继节点完成对N个参考信号的测量后，即可确定N个参考信号的测量结果。那么S601中，中继节点向基站上报N个参考信号中的至少一个参考信号的测量结果时包含两种情况：第一种情况，中继节点根据N个参考信号的测量结果筛选出至少一个参考信号，并将至少一个参考信号的测量结果上报给基站，这里，中继节点筛选出的至少一个参考信号可以是接入链路对回传链路干扰较小时用户设备对应发送的参考信号；第二种情况，中继节点不执行筛选动作，直接将N个参考信号的测量结果上报给基站。
需要说明的是，至少一个参考信号的测量结果中不仅可以包含至少一个参考信号的参数，例如RSRP、CQI、SIR和SINR，还可以包括至少一个参考信号的标识和配置信息，这是因为：如果中继节点仅向基站发送至少一个参考信号的RSRP、CQI、SIR和SINR等参数中的一个或多个，基站难以辨识出至少一个参考信号是用户设备向中继节点发送的N个参考信号中的哪些参考信号。因此，中继节点可在测量结果中发送该至少一个参考信号的标识和配置信息，从而用于基站辨识该至少一个参考信号。其中，至少一个参考信号的配置信息包括以下信息中的至少一种：至少一个参考信号的发送时间；至少一个参考信号的载波频率；至少一个参考信号的序列；至少一个参考信号的子载波间隔；至少一个参考信号的端口信息；至少一个参考信号的参考信号索引。
此外，在中继节点向基站发送至少一个参考信号的测量结果之前，基站可向中继节点发送资源配置信息，该资源配置信息用于指示中继节点发送至少一个参考信号的测量结果时所使用的资源。那么，中继节点在接收到资源配置信息后即可在资源配置信息指示的资源上向基站发送测量结果。
可选地，在中继节点向基站发送测量结果之前，基站可以向中继节点发送第一配置信息，第一配置信息为N个参考信号的配置信息。其中，N个参考信号的配置信息包括以下信息中的至少一种：N个参考信号的发送时间；N个参考信号的载波频率；N个参考信号的序列；N个参考信号的子载波间隔；N个参考信号的端口信息；N个参考信号的参考索引。
需要说明的是，基站可以主动向中继节点发送第一配置信息，也可以基于中继节点的请求向中继节点发送第一配置信息，本申请实施例中对此不做限定。此外，由于用户设备在向中继节点发送参考信号时可以基于不同的numerology发送，因而基站向中继节点发送的第一配置信息中还可指示用户设备在向中继节点发送参考信号时基于哪个numerology进行发送。
在基站向中继节点发送第一配置信息之后，中继节点可将第一配置信息发送给用户设备，那么用户设备在向中继节点发送上述N个参考信号时，可以基于第一配置信息进行发送。在用户设备向中继节点发送参考信号的同时，中继节点也可以根据第一配置信息对N个参考信号进行测量。
具体地，用户设备向中继节点发送的N个参考信号可以采用不同的赋形波束进行发送。例如，用户设备可分别采用N个赋形波束向中继节点发送N个参考信号，此时，第一配置信息即可用于指示用户设备在发送参考信号时采用的是哪个赋形波束。那么，中继节点可根据第一配置信息测量N个赋形波束下中继节点和用户设备间的链路(即接入链路)对基站和中继节点间的链路(即回传链路)的干扰。
此外，在图6所示方法中，基站在接收到中继节点发送的至少一个参考信号的测量结果后，可根据该测量结果进一步对至少一个参考信号进行筛选，并在筛选后向中继节点发送第二配置信息，第二配置信息为至少一个参考信号中的全部或部分参考信号的配置信息。其中，全部或部分参考信号的配置信息包括以下信息中的至少一种：全部或部分参考信号的发送时间；全部或部分参考信号的载波频率；全部或部分参考信号的序列全部或部分参考信号的子载波间隔；全部或部分参考信号的端口信息；全部或部分参考信号的参考信号索引。
其中，基站筛选出的全部或部分参考信号可以是接入链路对回传链路干扰较小时用户设备对应发送的参考信号。特别地，当用户设备分别采用N个赋形波束向中继节点发送N个参考信号时，中继节点筛选出的至少一个参考信号与至少一个赋形波束一一对应。假设基站筛选出的全部或部分参考信号的数量为M，M≥1，那么也有M个赋形波束与该M个参考信号一一对应。也就是说，基站向中继节点发送的第二配置信息指示了用户设备在采用上述M个赋形波束向中继节点发送M个参考信号时，接入链路对回传链路的干扰较小。那么，中继节点在接收到第二配置信息后即可通知用户设备：在后续向中继节点发送信号时，可采用上述M个赋形波束进行发送，从而减小接入链路对回传链路的干扰。
可选地，基站向中继节点发送的第二配置信息还可指示全部或部分参考信号的测量结果排序情况。例如，中继节点在S601中向基站发送的至少一个参考信号的测量结果为至少一个参考信号的RSRP，那么基站在从至少一个参考信号中筛选出全部或部分参考信号后、在向中继节点发送第二配置信息时，还可在第二配置信息中指示全部或部分参考信号的RSRP按照从高到低或者从低到高的排序情况。
此外，在图6所示的干扰测量方法中，为了使得测量结果更为准确，用户设备每次向中继节点发送参考信号的同时，基站也可在同一个时频资源上向中继节点发送参考信号，为了便于区分，实施例三中将基站发送给中继节点的参考信号称为“第二参考信号”。当用户设备和基站在同一个时频资源上向中继节点发送参考信号时，接入链路和回传链路中同时存在数据传输，因而这种情况下中继节点对N个参考信号的测量结果会更为准确。特别地，在上述过程中，基站向中继节点发送的第二参考信号可以是ZP RS。也就是说，中继节点会在同一个时频资源上接收到用户设备发送的、用于干扰测量的参考信号，以及接收基站发送的ZP RS，此时，由于接入链路和回传链路均占用该时频资源，因而在该时频资源上的参考信号传输不会受到其他信号的干扰，中继节点可在该时频资源上对参考信号进行测量，测量结果更为准确。
在图6所示的干扰测量方法中，中继节点向基站发送至少一个参考信号的测量结果，其中，至少一个参考信号为用户设备向中继节点发送的N个参考信号中的至少一个参考信号。基站可根据至少一个参考信号的测量结果从至少一个参考信号中筛选出全部或部分参考信号，并将全部或部分参考信号的配置信息发送给中继节点。其中， 基站筛选出的全部或部分参考信号可以是接入链路对回传链路干扰较小时用户设备对应发送的参考信号。中继节点将全部或部分参考信号的配置信息发送给用户设备后，用户设备在后续向中继节点发送信号时可以基于该全部或部分参考信号的配置信息发送，从而减小接入链路对回传链路的干扰。
基于以上对实施例三的描述，本申请实施例还提供一种干扰测量方法，该干扰测量方法可视为图6所示方法的一个具体示例，该方法和图6所示方法可相互参见。参见图7，该方法包括如下步骤：
S701：用户设备向中继节点发送请求消息，请求基站配置用户设备向中继节点发送参考信号时所使用的时频资源。
其中，用户设备向中继节点发送参考信号时所使用的时频资源可视为图6所示方法中第一配置信息的一个具体示例。
如前所述，第一配置信息为用户设备向中继节点发送的N个参考信号的配置信息。N个参考信号的配置信息包括以下信息中的至少一种：N个参考信号的发送时间；N个参考信号的载波频率；N个参考信号的序列；N个参考信号的子载波间隔；N个参考信号的端口信息；N个参考信号的参考信号索引。那么，在图7所示方法中，用户设备向中继节点发送参考信号时所使用的时频资源可视为N个参考信号的发送时间和N个参考信号的载波频率。
S702：中继节点将用户设备发送的请求消息转发给基站。
S703：基站向中继节点发送响应消息，以配置用户设备向中继节点发送参考信号时所使用的时频资源。
此外，S703中，基站还可配置自身在上述时频资源上向中继节点发送N个ZP RS。其中，ZP RS为图6所示方法中第二参考信号的一个具体示例。由于ZP RS的功率为零，因而基站实际上并没有向中继节点发送参考信号，而只是占用了基站和中继节点之间的时频资源。这样做的好处是：中继节点在同一个时频资源上接收来自用户设备的、用于干扰测量的N个参考信号，以及接收来自基站的N个ZP RS，此时，该时频资源上发送的参考信号不会受到其他信号的干扰，中继节点在该时频资源上对参考信号进行测量，测量结果更为准确。
S703中，基站向中继节点发送的响应消息可以是高层信令或DCI。其中，高层信令包括但不限于：RRC消息、MAC CE、广播消息、系统消息等。
S704：用户设备在上述时频资源上采用N个赋形波束中的一个赋形波束向中继节点发送参考信号。
S705：中继节点测量该赋形波束下接入链路对回传链路的干扰。
具体地，中继节点可在ZP RS所占用的时频资源上测量参考信号的RSRP、CQI、SIR和SIN等参数，从而确定该赋形波束下接入链路对回传链路的干扰。
将S704～S705执行N次：即每次执行S704时用户设备均采用不同的赋形波束向中继节点发送参数信号，每次执行S705时中继节点测量每个赋形波束下接入链路对回传链路的干扰。那么，通过将S704～S705执行N次，中继节点可确定N个赋形波束下接入链路对回传链路的干扰。
S706：中继节点向基站上报测量结果。
其中，中继节点向基站上报的测量结果为N个参考信号中的至少一个参考信号的 测量结果。这里包含两种情况：第一种情况，中继节点根据N个参考信号的测量结果筛选出至少一个参考信号，并将至少一个参考信号的测量结果上报给基站，这里，中继节点筛选出的至少一个参考信号可以是接入链路对回传链路干扰较小时用户设备对应发送的参考信号；第二种情况，中继节点不执行筛选动作，直接将N个参考信号的测量结果上报给基站。
S707：基站向中继节点发送通知消息，以通知用户设备在向中继节点发送信号时可以使用的赋形波束集合。
其中，基站通过通知消息指示的赋形波束集合可以是单个的赋形波束，也可以是一组赋形波束的集合。
S707中，基站在接收到中继节点上报的至少一个参考信号的测量结果后，从至少一个参考信号中筛选出全部或部分参考信号，这里，基站筛选出的全部或部分参考信号可以是接入链路对回传链路干扰较小时用户设备对应发送的参考信号。
由于用户设备分别采用N个赋形波束向中继节点发送N个参考信号，因而N个参考信号与N个赋形波束是一一对应的，至少一个参考信号与至少一个赋形波束也是一一对应的，同样道理，假设基站筛选出的全部或部分参考信号的数量为M，M≥1，那么也有M个赋形波束与该M个参考信号一一对应。也就是说，基站在通知消息中指示的赋形波束集合包含与M个参考信号一一对应的M个赋形波束。
显然，中继节点在接收到上述通知消息后可将该通知消息转发给用户设备，用户设备可在后续向中继节点发送信号时采用该赋形波束集合中的赋形波束进行发送，以减小接入链路对回传链路的干扰。
S707中，基站通过通知消息向中继节点指示的赋形波束集合可视为图6所示方法中的第二配置信息的一个具体示例。图6所示方法中，第二配置信息为至少一个参考信号中的全部或部分参考信号的配置信息，而图7所示方法中，赋形波束集合为基站筛选出的、至少一个赋形波束中的全部或部分赋形波束；由于图7所示方法中，N个赋形波束和N个参考信号是一一对应的，因而基站通过通知消息指示用户设备采用至少一个赋形波束中的全部或部分赋形波束发送信号，即相当于图6所示方法中基站向中继节点发送至少一个参考信号中的全部或部分参考信号的配置信息(即第二配置信息)。
S707中，基站向中继节点发送的通知消息可以是高层信令或DCI。其中，高层信令包括但不限于：RRC消息、MAC CE、广播消息、系统消息等。
此外，在图7所示方法中，中继节点和基站间进行信号传输所使用的赋形波束不同时，基站在S707中向中继节点发送的赋形波束集合中包含的赋形波束可以相同，也可以不同。例如，当中继节点在S702中采用赋形波束A向基站发送请求消息、基站在S703中采用赋形波束B向中继节点发送响应消息时，S707中基站向中继节点发送的赋形波束集合中包含赋形波束1、赋形波束2和赋形波束3；那么，当中继节点在S702中采用赋形波束C向基站发送请求消息、基站在S703中采用赋形波束D向中继节点发送响应消息时，S707中基站向中继节点发送的赋形波束集合中包含的赋形波束可以是赋形波束1、赋形波束2和赋形波束3，也可以是赋形波束4、赋形波束5和赋形波束6。
通过图7所示方法，基站可以配置用户设备向中继节点发送信号时所使用的赋形 波束集合，从而减小接入链路对回传链路的干扰。
