具体实施方式
下面参照附图对本公开进行更全面的描述，其中说明本公开的示例性实施例。下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。下面结合各个图和实施例对本公开的技术方案进行多方面的描述。
此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。
在发明人所知晓的相关技术中，采用暂停基站服务或在受扰基站和施扰基站中设置专门时频资源发送和接收干扰测量参考信号的方法，会影响基站正常服务并造成额外的资源开销。目前部署5G TDD系统中，主要针对To C客户的业务需求，全网基站均采用统一的帧结构和上下行时隙配比，没能真正体现灵活的无线空口优势。而部分垂直行业场景在不同区域和时间段，上下行的业务需求是不同的，需要不同的上下行时隙结构，从而产生交叉链路干扰(Cross-Link Interference，CLI)，即基站间的下行干扰上行，终端间的上行干扰下行。因此，排除基站间干扰对提高通信质量具有重要意义。
在相关技术标准中并没有定义如何对基站间干扰进行测量，即使某些技术实现了对基站间干扰的测量，但通常准确性较低，不具备实用性，而且会在受扰基站和施扰基站中设置专门时频资源发送和接收干扰测量参考信号，这会造成额外的资源开销。
为此，本公开首先提供了一种交叉链路干扰的测量方法，该方法可以克服以上缺陷，能够准确有效地测量基站间的交叉链路干扰，方法实用性强，并且不会造成额外的资源开销。本公开实施例的方案可以应用于各种4G、5G、LTE等各种类型的通信网络中。
本公开实施例的实施终端可以是服务器、计算机等各种能够部署于基站内的设备，也可以是虽然位于基站之外，但能够与基站通信的设备。
图1是根据一些示例性实施例示出的一种交叉链路干扰的测量方法的系统架构示意图。如图1所示，该系统架构100包括受扰基站101、施扰基站102以及终端设备103，终端设备103通过无线通信网络接入了受扰基站101，受扰基站101与施扰基站102之间可以进行通信。当本公开提供的一种交叉链路干扰的测量方法应用于图1所示系统架构中时，一个具体过程可以是这样的：首先，受扰基站101向终端设备103发送时频资源配置信息，该时 频资源配置信息指示终端设备103在时频资源位置处不发送探测参考信号，受扰基站101还通过接口向施扰基站102发送时频资源位置信息，其中，时频资源配置信息指示的时频资源位置与时频资源位置信息所指示的时频资源位置相同；接着，施扰基站102向受扰基站101发送多维信号属性配置信息；随后，当进行干扰测量时，终端设备103在时频资源配置信息指示的时频资源位置处不向受扰基站101发送探测参考信号，施扰基站102则按照多维信号属性配置信息在时频资源位置信息所指示的时频资源位置处向受扰基站101发送干扰测量参考信号，受扰基站便可以识别出干扰测量参考信号；最后，受扰基站101可以根据干扰测量参考信号和底噪RSSI生成干扰分析报告。
在本公开的一些实施例中，多维信号属性配置信息包括波束方向图样信息和功率配置信息，波束方向图样信息用于表示波束发射角度，功率配置信息用于表示信号发射功率。
在本公开的一些实施例中，受扰基站101根据获得的多个干扰测量参考信号和底噪RSSI生成多维度干扰分析报告。
值得一提的是，图1仅为本公开的一些实施例，虽然在图1实施例中，干扰分析报告是由受扰基站根据干扰测量参考信号直接生成的，但在本公开的其他实施例中，受扰基站还可以先对干扰测量参考信号进行处理，生成原始数据，然后将原始数据发送至其他终端或基站上，由其他终端或基站生成干扰分析报告。本公开实施例对此不作任何限定，本公开的保护范围也不应因此而受到任何限制。
图2是根据一些示例性实施例示出的交叉链路干扰的测量方法的流程图。图2实施例提供的交叉链路干扰的测量方法可以由基站执行，具体可以由受扰基站执行，如图2所示，可以包括以下步骤：
步骤210，向终端发送时频资源配置信息，并向施扰基站发送时频资源位置信息，时频资源配置信息和时频资源位置信息指示着进行基站间干扰测量时所使用的同一时频资源位置，时频资源配置信息用于指示终端在时频资源位置处不发送探测参考信号。
时频资源配置信息和时频资源位置信息可以是同样的信息，都指示着同样的时频资源位置，比如，时频资源配置信息可以包括时频资源位置信息。两者区别在于，时频资源配置信息是向终端发送的，时频资源位置信息是向施扰基站发送的。当然，时频资源配置信息和时频资源位置信息除了均包括同样的时频资源位置之外，还可以包括其他不同的信息。终端可以是接入了受扰基站的智能手机等终端设备。
时频资源位置可以包括频率和时隙，频率和时隙可以是周期性或非周期性的。时频资源配置信息中的时频资源位置用于指示终端在该时频资源位置上发送SRS(探测参考信号，Sounding Reference Signal)，时频资源位置信息中的时频资源位置用于指示施扰基站在 该时频资源位置上发送干扰测量参考信号。
在本公开的一些实施例中，向施扰基站发送时频资源位置信息，包括：
通过与施扰基站之间的接口，向施扰基站发送时频资源位置信息。
具体地，可以通过Xn接口或X2接口，向施扰基站发送时频资源位置信息。
Xn接口和X2接口均为基站之间的网络接口，可以支持数据和信令的直接传输。
图3是根据一些示例性实施例示出的测量交叉链路干扰的原理示意图。请参见图3所示，在该系统中提供了受扰小区和施扰小区，受扰小区和施扰小区分别位于受扰基站和施扰基站中，从而可以在受扰小区和施扰小区之间进行干扰测量。
步骤220，获取施扰基站发来的多维信号属性配置信息。
其中，多维信号属性配置信息包括波束方向图样信息和功率配置信息，波束方向图样信息用于表示波束发射角度，功率配置信息用于表示信号发射功率。
施扰基站提供的多维信号属性配置信息可以是根据自身的天线配置等属性信息确定的。
请继续参见图3，右下角示出了一个表格，该表格为干扰测量CLI-RS(CLI-Reference Signal，交叉链路干扰参考信号)的配置，表格中包括三列信息，分别是配置、波束和功率，其中，波束一列中的每项信息便可以是一个波束方向图样信息，比如，30°表示波束发射角度为30度，波束方向图样信息可以表示SSB波束方向或PDSCH波束方向；功率一列中的每项信息是一个信号发射功率。因此，功率配置信息可以配置为满功率、递减3dB等。
步骤230，接收施扰基站按照多维信号属性配置信息在时频资源位置信息所指示的时频资源位置处发送的干扰测量参考信号。
当受扰基站接收到不同信号源在同一时频资源位置处发送的不同信号时，无法对不同的信号进行分辨。由于终端在该时频资源位置处不发送探测参考信号，这样就可以识别出同一时频资源位置的干扰测量参考信号，避免信号干扰，进而可以进行干扰测量。因此，可以复用原有的时频资源，无需额外占用新的时频资源，从而减少了资源开销。
请继续参见图3，slot即为信号的时隙，SRS配置便是时频资源配置信息，终端向受扰小区不发射SRS，不发射SRS所指向的SRS配置中的slot3和slot4这两个时隙即属于时频资源配置信息所指示的时频资源位置，在这两个时隙不发送信号，但在其他时隙发送信号。
请继续参见图3，施扰小区向受扰小区发射干扰测量的参考信号CLI-RS即为干扰测量参考信号，施扰小区下方的图示中slot3和slot4这两个时隙处发送非零的信号，这代表 干扰测量参考信号是在这两个时隙处发送的。
步骤240，根据干扰测量参考信号和底噪RSSI生成干扰分析报告。
受扰基站接收到干扰测量参考信号的同时，还会获得底噪RSSI，在此基础上，可以进一步根据已知的施扰基站的位置、天线朝向、施扰基站发来的多维信号属性配置信息等多种信息综合分析，生成干扰分析报告。
在本公开的一些实施例中，根据干扰测量参考信号和底噪RSSI生成干扰分析报告，包括：在时频资源位置信息所指示的时频资源位置处提取干扰测量参考信号；测量干扰测量参考信号的强度和接收的信号强度指示；根据干扰测量参考信号的强度和接收的信号强度指示生成干扰分析报告。
RSSI(Received Signal Strength Indication，接收的信号强度指示)是对无线信号强度的度量。
可以根据各种规则或算法来基于干扰测量参考信号的强度和接收的信号强度指示生成干扰分析报告。
在本公开的一些实施例中，多维信号属性配置信息为多组，根据干扰测量参考信号和底噪RSSI生成干扰分析报告，包括：根据获得的多个干扰测量参考信号和底噪RSSI生成多维度干扰分析报告，其中，每一干扰测量参考信号是施扰基站按照一组多维信号属性配置信息发送的。
具体地，请参见图3，在右下角示出的表格中包含多组波束和功率的配置，施扰小区/基站在时频资源位置处按照每一组配置向受扰小区/基站按发射干扰测量参考信号，从而使得受扰小区/基站能够得到多个干扰测量参考信号。
在本公开实施例中，通过获取施扰基站基于不同的多维信号属性配置信息发来的干扰测量参考信号，能够获取到施扰基站在不同条件下发送的干扰测量参考信号，进而生成多维度干扰分析报告，提高了生成的干扰分析报告的准确性。
在本公开的一些实施例中，在根据干扰测量参考信号和底噪RSSI生成干扰分析报告之后，该方法还包括：根据干扰分析报告生成干扰消除策略。
通过机器学习等模型来根据干扰分析报告生成干扰消除策略；也可以预先为不同类型的干扰分析报告配置相应的干扰消除策略，然后根据干扰分析报告所属的类型来确定相应的干扰消除策略。
图4是根据一些示例性实施例示出的交叉链路干扰的测量方法的具体实施流程示意图。下面，结合图4进一步介绍本公开实施例的方案：
首先，在终端和受扰基站之间执行步骤1，并在受扰基站和施扰基站之间执行步骤2：
1、基站配置SRS，指配时频资源。
2、通过基站间接口，传递SRS配置信息。
接着，在施扰基站选择波束方向图样和功率配置之后，在施扰基站和受扰基站之间执行步骤3：
3、传递波束方向图样和功率配置。
然后，在终端和受扰基站之间执行步骤4-1，同时在施扰基站和受扰基站之间执行步骤4-2：
4-1、在已配置时频位置不发送SRS。
4-2、在相同时频资源位置发送干扰测量参考信号CLI-RS。
最后，在受扰基站执行步骤5：
5、测量干扰参考信号的强度和RSSI，形成不同波束方向和功率配置下的干扰分析报告。
综上所述，本公开实施例通过在现有无线网中，通过受扰基站对终端发送SRS的时频资源进行个性化配置，指定终端在部分时频资源位置不发送SRS，通过基站间的交互接口把配置传递给施扰站。施扰基站在该配置的时频资源位置中选择不同的波束方向和功率发送干扰测量的参考信号CLI-RS，受扰基站测量施扰基站的参考信号，复用了原有的SRS时频资源，减少了资源开销，从而实现在不占用新的时频资源前提下，对基站间的交叉链路干扰进行多维度测量和分析，提高干扰测量的有效性和准确性，为基站间交叉链路干扰的干扰消除和规避策略提供依据。
根据本公开的第二方面，本公开还提供了另一种交叉链路干扰的测量方法。
图5是根据另一些示例性实施例示出的交叉链路干扰的测量方法的流程图，该交叉链路干扰的测量方法可以由施扰基站执行，如图5所示，可以包括以下步骤：
步骤510，获取由受扰基站发来的时频资源位置信息，其中，时频资源位置信息和时频资源配置信息指示着进行基站间干扰测量时所使用的同一时频资源位置，时频资源配置信息是由受扰基站向终端发送的，时频资源配置信息用于指示终端在时频资源位置处不发送探测参考信号。
步骤520，向受扰基站发送多维信号属性配置信息。
其中，多维信号属性配置信息包括波束方向图样信息和功率配置信息，波束方向图样信息用于表示波束发射角度，功率配置信息用于表示信号发射功率。
步骤530，按照多维信号属性配置信息在时频资源位置信息所指示的时频资源位置处向受扰基站发送干扰测量参考信号，以使受扰基站在接收到干扰测量参考信号之后，根据 干扰测量参考信号和底噪RSSI生成干扰分析报告。
本公开所提供的交叉链路干扰的测量方法，通过先分别向终端和施扰基站提供时频资源位置信息，然后获取由施扰基站提供的多维信号属性配置信息，这样，受扰基站便可以获得由施扰基站按照多维信号属性配置信息在时频资源位置处发送的干扰测量参考信号和底噪RSSI，进而可以基于干扰测量参考信号和底噪RSSI生成干扰分析报告。由于施扰基站提供的多维信号属性配置信息反映了关于施扰基站的多方面信号信息，因此，干扰分析报告实现了多方面的干扰测量和评估，从而能够准确测量施扰基站和受扰基站间的交叉链路干扰，进而为干扰消除提供了决策依据；此外，由于时频资源配置信息用于指示终端在时频资源位置处不发送探测参考信号，因此，在终端与受扰基站进行正常通信的过程中也可以分辨出干扰测量参考信号，从而在不占用新的时频资源的条件下能够实现干扰测量。
根据本公开的第三方面，本公开还提供了一种交叉链路干扰的测量装置，该装置可以位于受扰基站中。
