一个例子中，SRS配置信息可以包括控制器为第二UE的第二服务基站分配的SRS资源。其中，该SRS资源由第二服务基站的基站标识和该SRS资源的SRS资源标识确定。或者，该SRS资源由第二服务基站的基站标识、该SRS资源所属的SRS资源集的SRS资源集标识和该SRS资源的SRS资源标识确定。

一个例子中，SRS资源可以是小区级SRS资源、或群组级SRS资源、或UE级SRS资源。若SRS资源是小区级SRS资源，目标SRS资源是所有候选SRS资源，目标SRS资源被分配至由第二服务基站管理的服务小区下的所有干扰UE。或者，若SRS资源是群组级SRS资源，目标SRS资源是所有候选SRS资源或部分候选SRS资源，目标SRS资源被分配至用户群组内的所有干扰UE，用户群组包括至少一个干扰UE。或者，若SRS资源是UE级SRS资源，目标SRS资源是至少一个候选SRS资源，目标SRS资源被分配至一个干扰UE。

一个例子中，若SRS配置信息包括K个第二服务基站对应的SRS资源，K可以为正整数，则该CLI测量结果可以包括K个子带内干扰测量字段和1个子带间干扰测量字段。K个子带内干扰测量字段与K个第二服务基站一一对应，且子带间干扰测量字段位于K个子带内干扰测量字段的后面。
其中，针对每个第二服务基站对应的子带内干扰测量字段，该子带内干扰测量字段包括该第二服务基站对应的CLI标识、该第二服务基站对应的每个SRS资源对应的SRS标识、该第二服务基站对应的每个SRS资源对应的SRS-RSRP。

一个例子中，第一UE向第一服务基站发送第一UE的CLI测量结果，可以包括：第一UE接收第一服务基站发送的CSI测量配置。若该CSI测量配置包括上报量，且该上报量用于指示上报 SRS-RSRP、或SRS-RSRP和CLI-RSSI，则第一UE向第一服务基站发送第一UE的CLI测量结果。
一个例子中，第一UE在第二UE使用的SRS资源上接收SRS信号之后，则：第一UE禁止在该SRS资源所在的时隙中接收PDSCH数据。或者，第一UE在该SRS资源所在的时隙中对PDSCH数据进行速率匹配。
由以上技术方案可见，在F-TDD系统或者SBFD系统中，UE间的CLI会影响系统整体性能。通过获取UE的CLI测量结果，就可以基于CLI测量结果实现UE间的协作调度，降低UE间的CLI，提高数据传输性能。
以下结合例子，对本申请的上述技术方案进行说明。
TDD系统可以工作在HD模式，即在同一个时刻，相同频域资源仅能用于UL或DL。为了更加灵活的使用频域资源，提高资源利用率，TDD系统也可以工作在FD(Full-Duplex，全双工)模式。在同一个时刻，相同频域资源同时用于UL和DL，也就是，在相同频域资源上同时处理上行数据和下行数据。
TDD系统中，帧结构被分成DL时隙、UL时隙和灵活时隙，帧结构一旦确定，UE可以按照帧结构进行数据收发。对于采用HD(Half Duplex，半双工)模式的UE，基站(如gNB等)根据帧结构调度UE进行发送或接收。对于采用FD模式的UE，基站根据帧结构调度UE的发送、接收或同时发送和接收。综上所述，基站可以配置帧结构，并向UE通知帧结构，以使UE获知帧结构，从而正确进行数据收发。从另一个角度，UE获知帧结构后，可以获知可能存在的UE间干扰，从而采用干扰消除技术来减轻干扰，提高通信可靠性。
在TDD系统下，帧结构按照时隙分为UL时隙、DL时隙和灵活时隙(F时隙)。灵活时隙中的符号可以被配置成UL符号、DL符号和F符号，F符号可以用于UL、DL或者GP。其中，上行数据可以在UL时隙传输、在灵活时隙中的UL符号或F符号传输，上行数据无法在DL时隙传输，也无法在灵活时隙中的DL符号传输。下行数据可以在DL时隙传输、在灵活时隙中的DL符号或F符号传输，下行数据无法在UL时隙传输，也无法在灵活时隙中的UL符号传输。
在TDD系统下，针对以上行传输为主的帧结构，通常UL时隙配置较多，这就造成DL时隙变少。导致下行传输速率受限，并增加下行数据的传输时延，导致下行传输的时延变大，不利用下行业务。针对以下行传输为主的帧结构，通常DL时隙配置较多，这就造成UL时隙变少。导致上行传输速率受限，并增加上行数据的传输时延，导致上行传输的时延变大，不利用上行业务。
可以通过F-TDD解决以上问题，F-TDD也称动态TDD，可以灵活分配UL时隙和DL时隙，能够满足业务动态变化的需求，提高通信系统的性能。
还可以通过SBFD解决以上问题，SBFD可以在BWP(Bandwidth Part，部分带宽)中配置SBFD子带资源(Subband，即频域资源)，SBFD子带资源包括上行子带资源和下行子带资源。这样，在同一时刻，在SBFD子带资源上，可以传输与其它频域资源不同方向的数据。提高上行数据速率，并降低空口时延。
比如说，在DL时隙中的BWP中配置SBFD子带资源，通过SBFD子带资源传输上行数据，使得上行数据在DL时隙传输。在灵活时隙的DL符号的BWP中配置SBFD子带资源，通过SBFD子带资源传输上行数据，使得上行数据在灵活时隙的DL符号传输。显然，通过下行时隙或者灵活时隙传输上行数据，能够提高上行传输速率，减少上行数据的传输时延。
比如说，在UL时隙中的BWP中配置SBFD子带资源，通过SBFD子带资源传输下行数据，使得下行数据在UL时隙传输。在灵活时隙的UL符号的BWP中配置SBFD子带资源，通过SBFD子带资源传输下行数据，使得下行数据在灵活时隙的UL符号传输。显然，通过上行时隙或者灵活时隙传输下行数据，能够提高下行传输速率，减少下行数据的传输时延。
无论是采用F-TDD还是SBFD，均存在UE间的干扰问题。参见图2所示，为F-TDD网络结构的示意图。宏基站(gNB0)的帧结构是DDDSU，微基站(gNB1)的帧结构是DSUUU。显然，在时隙#2中，gNB0是下行时隙(D时隙)，gNB1是上行时隙(U时隙)，即gNB0和gNB1的传输方向不同。
在时隙#2中，gNB0向UE0发送DL数据，gNB1接收来自UE1的UL数据。在这种情况下，gNB0的DL数据发送会对gNB1的UL数据接收产生干扰，即gNB-gNB的CLI。UE1的UL数据发 送会对UE0的DL数据接收产生干扰，即UE-UE的CLI。以上两种干扰是同频干扰，同频干扰也存在于SBFD系统中。
为了便于描述，将服务受害UE和干扰UE的基站统称为服务基站，将干扰其它UE的UE称为干扰(Aggressor)UE，而被干扰的UE称为受害(Victim)UE。被干扰的基站或者服务受害UE的基站称为受害基站，而对受害基站产生干扰的基站或者服务干扰UE的基站称为干扰基站。其中，同一服务基站下可能会同时存在受害UE和干扰UE，从UE的角度，服务基站可能同时是受害基站和干扰基站，干扰和受害的主体不是基站，而是基站服务的UE。
无论是gNB-gNB的CLI，还是UE-UE的CLI，均会对基站和UE的接收造成影响，使接收信噪比下降，造成误码率上升，最终影响TDD系统的整体性能。
针对UE-UE的CLI，本申请提出一种CLI测量方法，通过测量UE-UE的CLI，得到UE-UE的CLI测量结果，就可以基于CLI测量结果实现UE间的协作调度，降低UE间的CLI，提高数据传输性能，提高TDD系统的整体性能。
一个例子中，针对同频CLI，UE-UE间的CLI包括子带内CLI和子带间CLI，子带内CLI存在于F-TDD系统和SBFD系统，子带间CLI存在于SBFD系统。
一个例子中，针对CLI测量方法，可以涉及如下过程：
第一、基站间帧结构配置和SBFD配置的交互。
无论是子带内CLI的测量还是子带间CLI的测量，均需要在基站之间交互配置信息，该配置信息可以包括帧结构的配置信息和SBFD的配置信息。
针对每个基站，该基站向其它基站发送配置信息时，该配置信息可以包括该基站的基站标识(ID)，即通过基站标识表示该配置信息属于该基站。其中，基站标识可以是该基站的唯一标识，如Physical Cell ID(物理层小区标识)等。
对于F-TDD系统和SBFD系统，可以交互帧结构的配置信息，帧结构的配置信息包括参考子载波间隔、帧结构周期、上下行时隙、灵活时隙等配置信息。
由于帧结构的配置是由TDD-UL-DL-ConfigCommon(上行下行的公共配置)、TDD-UL-DL-ConfigDedicated(上行下行的专用配置)及时隙格式指示共同完成，且后两者仅能更改TDD-UL-DL-ConfigCommon中的灵活符号。因此，基站可以在TDD-UL-DL-ConfigCommon的基础上，考虑已经被更改后的灵活符号的类型，获得已生效的帧结构的配置信息，然后与其它基站进行交换。
帧结构的配置信息可以包括帧结构所使用的子载波间隔(SCS)和两个帧结构图样(Pattern)，每个图样包括该图样中的帧结构周期、DL时隙、DL符号、UL时隙和UL符号等，帧结构的配置信息的详细参数如表1所示。
对于SBFD系统，除了交互帧结构的配置信息，还可以交互SBFD的配置信息，如子带(Subband)的时域配置信息和频域配置信息。
其中，Subband可以被配置成DL Subband、UL Subband或者灵活(Flexible)Subband，三者可以同时配置，也可以仅配置其中一个或两个。
在时域上，每个Subband的时域位置由两个参数构成：Subband的起始符号和Subband所占据的符号长度。起始符号从每个帧结构图样的第一个符号开始算起，符号长度是从起始符号算起的所占用的符号数量。此外，任意两个不同类型的SBFD在符号上不应该重合，如果出现重叠，则认为是错误配置。
在频域上，每个Subband的频域位置由两个参数构成：Subband的起始PRB(Physical Resource Block，物理资源块)数和Subband占据PRB数量。起始PRB从BWP的第一个PRB开始算起，PRB数量从起始PRB开始占用的PRB数量。
在同一符号中，如果一部分PRB被配置成UL Subband(或DL Subband)，则剩余的PRB默认为DL Subband(或UL Subband)和保护带宽(Guardband)，且两个不同Ssubband之间会默认存在保护带宽。保护带宽的大小可以从若干个固定值中选择，如可以从{1,2,3,4,5,6,7,8}中选择保护带宽的大小。
如果Subband被配置成Flexible，则同一符号中剩余的PRB的用途，与该符号在帧结构中被配置的用途相同。比如说，若该符号被配置成DL符号，则剩余的PRB用于下行。如果灵活Subband在实际使用中与其余的PRB的传输方向不同，那么，默认保护带宽可以位于灵活Subband中。
一个例子中，SBFD的配置信息的详细参数如表1所示。
表1

一个例子中，基站间交互帧结构的配置信息、SBFD的配置信息时，可以通过Xn、F2接口或空口实现。为了方便信息交换，可以由控制器来实现基站间的信息交换，例如，每个基站将帧结构的配置信息、SBFD的配置信息发送给控制器，控制器将每个基站的帧结构的配置信息、SBFD的配置信息发送给其它基站。
一个例子中，该控制器可以是某一个基站，也可以是系统中控制不同DU的CU单元，还可以是其它用于统一控制每个基站的控制单元，对此不做限制。
第二、UE-UE的CLI测量过程。其中，对于F-TDD系统和SBFD系统，存在子带内CLI的测量，对于SBFD系统，存在子带间CLI的测量。
对于F-TDD系统和SBFD系统，参见图3A所示，为UE间子带内CLI测量和上报的示意图。gNB0是宏基站，覆盖面积较大，用于大面积覆盖。gNB1是微基站，覆盖面积较小，用于室内补盲。gNB1内的UE1发送上行信号时，会对gNB0内的UE0的下行接收产生CLI。UE1是干扰UE，UE1的服务基站gNB1是干扰基站，UE0是受害UE，UE0的服务基站gNB0是受害基站。
可以将受害UE称为第一UE，将受害UE的服务基站称为第一服务基站，将干扰UE称为 第二UE，将干扰UE的服务基站称为第二服务基站。基于此，第一UE是UE0，第一服务基站是gNB0，第二UE是UE1，第二服务基站是gNB1。
参见图3A所示，UE间子带内CLI测量和上报过程，可以包括以下步骤：
步骤0、第一服务基站确定第一UE为受害UE后，向控制器发送干扰消息。
一个例子中，若第一服务基站检测到第一UE在固定时隙(一个或多个固定时隙)的下行数据传输失败，且第一服务基站基于相邻基站的帧结构(基站之间已交互帧结构的配置信息，可以获知相邻基站的帧结构)确定相邻基站在固定时隙为上行时隙或者灵活时隙，则第一服务基站确定第一UE为受害UE。
比如说，若第一服务基站通过HARQ NACK检测到第一UE在固定时隙的下行数据传输失败，且下行数据传输失败的次数达到预设阈值(如3、5等)，则第一服务基站基于相邻基站的帧结构确定相邻基站(一个或多个)在固定时隙是否为上行时隙或者灵活时隙。若是，则第一服务基站确定第一UE为受害UE，即，第一UE受到相邻基站中的第二UE的交叉链路干扰。
比如说，对于某一时隙，若第一服务基站在该时隙进行下行调度，第二服务基站在该时隙进行上行调度，那么，第一服务基站在该时隙调度第一UE进行下行数据传输时，可能会受到第二服务基站中的第二UE的上行传输的干扰。
基于此，第一服务基站检测到第一UE在该时隙的下行数据传输失败，且基于第二服务基站的帧结构确定第二服务基站在该时隙为上行时隙。
一个例子中，若第一服务基站检测到第一UE在固定时隙的下行数据传输失败，且第一服务基站基于相邻基站的SBFD配置(基站之间已交互SBFD的配置信息，可以获知SBFD配置)确定相邻基站在固定时隙配置SBFD资源，且SBFD资源用于上行子带，则第一服务基站确定第一UE为受害UE。
比如说，若第一服务基站通过HARQ NACK检测到第一UE在固定时隙的下行数据传输失败，且下行数据传输失败的次数达到预设阈值，则第一服务基站基于相邻基站的SBFD配置确定相邻基站在固定时隙是否配置SBFD资源，且SBFD资源是否用于上行子带。若是，则第一服务基站确定第一UE为受害UE，即，第一UE受到相邻基站中的第二UE的交叉链路干扰。
比如说，对于某一时隙，第一服务基站将该时隙的部分PRB配置成下行子带，而第二服务基站将该部分PRB配置成上行子带，那么，第一服务基站在该部分PRB调度第一UE进行下行数据传输时，可能会受到第二服务基站中的第二UE的上行传输的干扰。基于此，第一服务基站检测到第一UE在该时隙的下行数据传输失败，且基于第二服务基站的SBFD配置确定第二服务基站在该时隙配置SBFD资源，且SBFD资源是否用于上行子带。
一个例子中，第一服务基站确定第一UE为受害UE后，还可以向控制器发送干扰消息，该干扰消息包括固定时隙的时隙位置和第一服务基站的基站标识，且该干扰消息用于表示本第一服务基站中UE受到相邻基站中UE的干扰。
步骤1、控制器在接收到该干扰消息之后，确定干扰基站(将该干扰基站称为第二服务基站，第二服务基站可以为一个或多个)，控制器获取SRS配置信息，并将该SRS配置信息发送给第一服务基站和第二服务基站。
一个例子中，控制器可以基于多个基站的帧结构(每个基站均会将帧结构的配置信息发送给控制器，即控制器可以得到每个基站的帧结构)确定第一服务基站的干扰基站，且干扰基站在固定时隙为上行时隙或者灵活时隙。
比如说，控制器可以从干扰消息中获取固定时隙的时隙位置，表示第一服务基站的该固定时隙存在干扰。若第一服务基站的某个相邻基站在该固定时隙为上行时隙或者灵活时隙(基于该相邻基站的帧结构获知)，则控制器将该相邻基站作为第一服务基站的干扰基站，即该相邻基站作为第二服务基站。
一个例子中，控制器基于多个基站的SBFD配置(每个基站将SBFD的配置信息发送给控制器，控制器得到每个基站的SBFD配置)确定第一服务基站的干扰基站，干扰基站在固定时隙配置SBFD资源，SBFD资源用于上行子带。
比如说，控制器可以从干扰消息中获取固定时隙的时隙位置。若第一服务基站的某个相邻基站在该固定时隙配置SBFD资源，且该SBFD资源用于上行子带(基于该相邻基站的SBFD配置获知)，则控制器将该相邻基站作为第一服务基站的干扰基站，即该相邻基站作为第二服务基站。
一个例子中，控制器根据组网情况和各基站的物理位置，确定第一服务基站的多个相邻基站，继而确定每个相邻基站是否为第一服务基站的干扰基站。
一个例子中，控制器确定出干扰基站之后，控制器为干扰基站下的干扰UE分配SRS(Sounding Reference Signal，探测参考信号)资源，即为第二服务基站下的第二UE分配SRS资源。其中，该SRS资源是目标时隙中的SRS资源，第二UE在该目标时隙发送上行数据，第一UE在该目标时隙接收下行数据。
比如说，控制器可以从所有时隙中选取出满足上述特征的时隙作为目标时隙，并为干扰基站下的干扰UE分配目标时隙中的SRS资源。
当然，上述只是分配SRS资源的示例，对此SRS资源的分配方式不做限制。
一个例子中，控制器在得到SRS资源之后，控制器可以将SRS配置信息发送给第一服务基站，并将SRS配置信息发送给第二服务基站。
其中，该SRS配置信息可以包括控制器为第二服务基站下的第二UE分配的SRS资源，即该SRS配置信息可以包括第二UE使用的SRS资源。
步骤2、第一服务基站在接收到SRS配置信息后，将该SRS配置信息发送给第一UE，第一UE接收该SRS配置信息。第二服务基站在接收到SRS配置信息后，将该SRS配置信息发送给第二UE，第二UE接收该SRS配置信息。
一个例子中，为了实现CLI测量，UE需要在接收下行数据的同时，对SRS信号进行测量。若UE支持上述功能，则需要引入额外的UE能力，如该能力为SimultaneousPDSCHandSRSmeasurement，UE在接入过程中，需要将此能力上报给基站，基站仅向支持该能力的UE下发用于CLI测量的SRS配置信息。
基于此，在第一UE的接入过程中，若第一UE具有同时进行数据接收和SRS测量的功能，则第一UE向第一服务基站发送第一UE的能力信息，该能力信息可以为SimultaneousPDSCHandSRSmeasurement。第一服务基站可以接收第一UE的该能力信息，并在指定存储介质中存储该能力信息。其中，该能力信息用于表示第一UE是否具有同时进行数据接收和SRS测量的功能。
比如说，若该能力信息为SimultaneousPDSCHandSRSmeasurement，则表示第一UE具有同时进行数据接收和SRS测量的功能。
第一服务基站在接收到SRS配置信息后，若该SRS配置信息用于CLI测量，则第一服务基站从指定存储介质中获取第一UE的能力信息。若第一服务基站基于该能力信息确定第一UE具有同时进行数据接收和SRS测量的功能，则第一服务基站向第一UE发送该SRS配置信息。否则，若指定存储介质未存储第一UE的能力信息，或，基于该能力信息确定第一UE不具有同时进行数据接收和SRS测量的功能，则第一服务基站禁止向第一UE发送该SRS配置信息。
其中，在该SRS配置信息用于CLI测量时，该SRS配置信息还可以包括CLI测量标识，且该CLI测量标识用于表示SRS资源是用于UE之间的CLI测量。基于此，第一服务基站确定该SRS配置信息包括CLI测量标识时，确定该SRS配置信息用于CLI测量，并向第一UE发送该SRS配置信息。
步骤3、第二UE在接收到SRS配置信息之后，该SRS配置信息包括控制器为第二UE分配的SRS资源，第二UE在该SRS资源上发送SRS信号。
步骤4、第一UE在接收到SRS配置信息之后，该SRS配置信息包括第二UE使用的SRS资源，第一UE在第二UE使用的该SRS资源上接收第二UE通过该SRS资源发送的SRS信号，该SRS信号可以用于获取该SRS资源对应的SRS-RSRP(Reference Signal Received Power，参考信号接收功率)。
一个例子中，第一UE在接收到SRS配置信息之后，若该SRS配置信息包括CLI测量标识， 且CLI测量标识用于表示SRS资源是用于UE之间的CLI测量，则第一UE在该SRS资源上接收第二UE通过该SRS资源发送的SRS信号。
第一UE在该SRS资源上接收到SRS信号时，可以对SRS信号的接收功率进行测量，得到该SRS资源对应的RSRP，将该RSRP记为SRS-RSRP。
步骤5、第一UE向第一服务基站发送第一UE的CLI测量结果，第一服务基站接收该CLI测量结果，该CLI测量结果可以包括该SRS-RSRP。
步骤6、第一服务基站将CLI测量结果上报给控制器。
一个例子中，若第一服务基站接收到一个第一UE(即只存在一个受害UE)的CLI测量结果，则将该第一UE的CLI测量结果上报给控制器。
若第一服务基站接收到多个第一UE(即存在多个受害UE)的CLI测量结果，则将多个第一UE的CLI测量结果进行汇总后上报给控制器。
步骤7、控制器基于第一服务基站上报的CLI测量结果进行协作调度。
一个例子中，若控制器接收到一个第一服务基站(即只存在一个受害服务基站)，则基于该第一服务基站的CLI测量结果进行协作调度，对此调度过程不做限制。若控制器接收到多个第一服务基站(即存在多个受害服务基站)，则基于多个第一服务基站的CLI测量结果进行协作调度，对此调度过程不做限制。通过协作调度，能够减少UE之间的干扰，提高数据传输性能。
对于SBFD系统，参见图3B所示，为UE间子带间CLI测量和上报的示意图。UE1发送上行信号时，会对UE0的下行接收产生CLI。UE1是干扰UE，UE1的服务基站是干扰基站，UE0是受害UE，UE0的服务基站是受害基站。可以将受害UE称为第一UE，将受害UE的服务基站称为第一服务基站，将干扰UE称为第三UE，将干扰UE的服务基站称为第三服务基站。
参见图3B所示，UE间子带间CLI测量和上报过程，可以包括以下步骤：
步骤0、第三服务基站向第三UE发送SRS配置信息，该SRS配置信息包括第三服务基站为第三UE分配的SRS资源，该SRS资源是SBFD资源的上行子带配置的SRS资源，即用于子带间CLI测量的SRS信号配置在UL Subband中。第一UE的DL subband与第三UE的UL subband不在同一频域资源位置上。
步骤1、第三UE在接收到SRS配置信息之后，该SRS配置信息包括第三服务基站为第三UE分配的SRS资源，第三UE可以在该SRS资源上发送SRS信号，或者，第三UE可以在上行子带(UL Subband)资源上发送PUSCH数据。
步骤2、第一UE对SBFD资源的下行子带接收的干扰信号进行测量得到干扰信号对应的CLI-RSSI(Received Signal Strength Indicator，接收信号强度指示)。
一个例子中，该干扰信号也称为测量信号，该干扰信号是第三UE在SRS资源上发送的SRS信号，或者，该干扰信号是第三UE在上行子带资源中发送的PUSCH数据。第一UE在SBFD资源的下行子带中测量所有干扰信号的RSSI，得到干扰信号对应的RSSI，将该RSSI记为CLI-RSSI。
步骤3、第一UE向第一服务基站发送第一UE的CLI测量结果，第一服务基站接收该CLI测量结果，该CLI测量结果可以包括该CLI-RSSI。
步骤4、第一服务基站基于该CLI测量结果进行协作调度。比如说，第一服务基站基于第一UE上报的CLI-RSSI，协调基站中各UE的调度。
第三、UE-UE的CLI测量信号。
一个例子中，对于UE-UE间的CLI测量，可以采用SRS信号作为CLI测量信号，即第二UE在SRS资源上发送SRS信号，第一UE在SRS资源上通过测量SRS信号的RSRP值来获得UE间CLI值，得到CLI测量结果。
在基站较多的情况下，可以通过控制器来统一协调配置SRS资源(即时频资源)，参见上述步骤1，控制器为第二服务基站下的第二UE分配SRS资源。
一个例子中，控制器在为第二服务基站下的第二UE分配SRS资源时，该SRS资源由第二服务基站的基站标识和该SRS资源的SRS资源标识唯一确定。或者，该SRS资源由第二服务基站 的基站标识、该SRS资源所属的SRS资源集的SRS资源集标识和该SRS资源的SRS资源标识唯一确定。
其中，由于控制器可以管理多个基站，为了区分不同基站下的SRS资源，控制器在分配SRS资源时，需要为SRS资源区分不同的基站标识，该基站标识可以为Physical Cell ID，也可以为其它类型标识，能够唯一标识基站即可。
其中，针对存在SRS资源集的场景，SRS资源集由SRS资源集标识来唯一确定。在每个SRS资源集用于波束管理、天线切换、码本传输、非码本传输及定位的基础上，可以对SRS资源集的功能进行扩展，用来支持UE间CLI测量。
比如说，需要额外为SRS资源集配置新的功能：CLI测量，以使SRS资源集支持CLI测量功能。比如说，在SRS资源集的配置参数中进行如下配置：usage ENUMERATED{beamManagement,codebook,nonCodebook,antennaSwitching，CLI measurement}，通过该配置表示SRS资源集支持CLI测量功能。
SRS资源集的上述配置参数可以为CLI测量标识，该CLI测量标识用于表示该SRS资源集内的每个SRS资源是用于UE之间的CLI测量。
其中，针对存在SRS资源集的场景，每个基站可以对应至少一个SRS资源集，且每个SRS资源集可以包括至少一个SRS资源，SRS资源由SRS资源标识来唯一确定。SRS资源的配置包括传输配置、时频域资源、跳频配置等。
其中，针对不存在SRS资源集的场景，每个基站可以对应至少一个SRS资源，SRS资源由SRS资源标识来唯一确定。SRS资源的配置包括传输配置、时频域资源、跳频配置等。可以对SRS资源的功能进行扩展，用来支持UE间CLI测量。比如说，需要额外为SRS资源配置新的功能：CLI测量，以使SRS资源支持CLI测量功能。比如说，在SRS资源的配置参数中进行如下配置：usage ENUMERATED{beamManagement,codebook,nonCodebook,antennaSwitching，CLI measurement}，通过该配置表示SRS资源支持CLI测量功能。
针对不存在SRS资源集的场景，SRS资源的上述配置参数可以为CLI测量标识，该CLI测量标识用于表示该SRS资源是用于UE之间的CLI测量。
一个例子中，针对存在SRS资源集的场景，每个用于CLI测量的SRS资源集(如SRS资源集内的多个SRS资源)可以配置成周期性(Periodic)、非周期性(Aperiodic)和半持续(Semi-persistent)。其中，对于非周期性的SRS资源集，可以通过DCI(Downlink Control Information，下行控制信息)进行触发。对于半持续的SRS资源集，可以通过MAC CE进行触发。
针对不存在SRS资源集的场景，每个用于CLI测量的SRS资源可以配置成周期性、非周期性和半持续。对于非周期性的SRS资源，可以通过DCI进行触发。对于半持续的SRS资源，可以通过MAC CE进行触发。
一个例子中，针对存在SRS资源集的场景，每个用于CLI测量的SRS资源集(如SRS资源集内的多个SRS资源)被配置成Cell-Specific、Group-Common或者UE-Specific。比如说，SRS资源集内的每个SRS资源可以是小区级SRS资源、或群组级SRS资源、或UE级SRS资源。为支持上述功能，可以在SRS资源集中引入新配置参数，该配置参数可以如srsResourceSetType ENUMERATED{Cell-specific，Group-Common，UE-Specific}。显然，若该配置参数为Cell-specific，则表示小区级SRS资源。若该配置参数为Group-Common，则表示群组级SRS资源。若该配置参数为UE-Specific，则表示UE级SRS资源。
针对不存在SRS资源集的场景，每个用于CLI测量的SRS资源可以被配置成Cell-Specific、Group-Common或者UE-Specific。比如说，每个SRS资源可以是小区级SRS资源、或群组级SRS资源、或UE级SRS资源。
一个例子中，针对上述步骤2，第二服务基站获取SRS配置信息之后，第二服务基站将SRS配置信息发送给第二UE时，可以采用如下方式：
第二服务基站从该SRS配置信息中获取与第二服务基站对应的至少一个候选SRS资源。比如说，由于SRS配置信息可以包括多个基站对应的SRS资源，且SRS资源可以通过基站标识和SRS资源标识唯一确定，因此，第二服务基站从该SRS配置信息中获取与本第二服务基站的基站标识对 应的SRS资源(至少一个)，将这些SRS资源作为候选SRS资源。或者，由于SRS资源可以通过基站标识、SRS资源集标识和SRS资源标识唯一确定，因此，第二服务基站从该SRS配置信息中获取与本第二服务基站的基站标识对应的SRS资源集(至少一个)，将每个SRS资源集内的所有SRS资源(至少一个)作为候选SRS资源。
第二服务基站从所有候选SRS资源中选取目标SRS资源，并将目标SRS资源分配至第二UE，以使第二UE在目标SRS资源上发送SRS信号。
比如说，若SRS资源是小区级SRS资源，则目标SRS资源是所有候选SRS资源，且目标SRS资源被分配至由第二服务基站管理的服务小区下的所有干扰UE(即第二UE)。即，对于配置给第二服务基站的小区级SRS资源，第二服务基站将所有候选SRS资源均作为目标SRS资源，并将目标SRS资源分配至服务范围内的所有干扰UE。针对每个干扰UE，在接收到SRS配置信息之后，该SRS配置信息包括目标SRS资源，该干扰UE在目标SRS资源上发送SRS信号。
比如说，若SRS资源是群组级SRS资源，则目标SRS资源可以是所有候选SRS资源或者部分候选SRS资源，且目标SRS资源被分配至用户群组内的所有干扰UE(即第二UE)，用户群组可以包括至少一个干扰UE。
第二服务基站可以将服务范围内的所有干扰UE划分到至少一个用户群组。针对每个用户群组，第二服务基站可以将所有候选SRS资源或者部分候选SRS资源分配给该用户群组，对此分配方式不作限制。第二服务基站可以将分配给该用户群组的候选SRS资源作为该用户群组的目标SRS资源，并将该目标SRS资源分配至该用户群组内的所有干扰UE。显然，对于配置给第二服务基站的群组级SRS资源，目标SRS资源适用于用户群组内的所有干扰UE。
针对每个干扰UE，在接收到SRS配置信息之后，该SRS配置信息包括目标SRS资源，该干扰UE在目标SRS资源上发送SRS信号。
比如说，若SRS资源是UE级SRS资源，则目标SRS资源可以是至少一个候选SRS资源，且目标SRS资源被分配至一个干扰UE(即第二UE)。
对于配置给第二服务基站的UE级SRS资源，UE级SRS资源仅针对一个干扰UE有效，即将UE级SRS资源分配给一个干扰UE，第二服务基站可以基于候选SRS资源的数量和干扰UE的数量，为每个干扰UE分配目标SRS资源。
若候选SRS资源的数量等于干扰UE的数量，则第二服务基站为每个干扰UE分配一个候选SRS资源，即候选SRS资源与干扰UE一一对应。可以将干扰UE对应的候选SRS资源作为该干扰UE的目标SRS资源。
若候选SRS资源的数量大于干扰UE的数量，则第二服务基站为每个干扰UE分配至少一个候选SRS资源，即每个干扰UE可以对应至少一个候选SRS资源，不同干扰UE对应的候选SRS资源不同即可。比如说，干扰UE1对应候选SRS资源1和候选SRS资源2，干扰UE2对应候选SRS资源3。可以将干扰UE对应的候选SRS资源作为该干扰UE的目标SRS资源。
若候选SRS资源的数量小于干扰UE的数量，则第二服务基站按照优先级高低的方式分配候选SRS资源，或者，采用轮询的方式分配候选SRS资源。比如说，干扰UE的优先级顺序为干扰UE3、干扰UE1、干扰UE2，则干扰UE3对应候选SRS资源1，干扰UE1对应候选SRS资源2。又例如，基于轮询的方式，干扰UE1对应候选SRS资源1，干扰UE2对应候选SRS资源2。可以将干扰UE对应的候选SRS资源作为该干扰UE的目标SRS资源。
一个例子中，针对上述步骤4，第一UE在接收到SRS配置信息之后，由于该SRS配置信息包括多个SRS资源(即多个第二UE使用的SRS资源)，因此，针对该SRS配置信息指示的每个SRS资源，第一UE在该SRS资源上接收SRS信号，该SRS信号可以用于获取该SRS资源对应的SRS-RSRP。
比如说，若SRS资源是小区级SRS资源，针对每个SRS资源，第二服务基站管理的服务小区下的所有干扰UE均会在该SRS资源上发送SRS信号，即第一UE在该SRS资源上接收SRS信号时，该SRS信号是服务小区下的所有干扰UE的SRS累加信号。第一UE基于该SRS资源上的SRS信号确定SRS-RSRP时，该SRS-RSRP是服务小区下所有干扰UE的SRS信号的累加RSRP值。
对于UE间CLI测量，一个受害UE可能会受到多个干扰基站中的多个干扰UE的干扰，为 了能够区分来自某个干扰基站中的某个干扰UE的CLI干扰，对于小区级SRS资源，可以将不同干扰基站下的SRS时频资源位置配置成不同。
比如说，若SRS资源是群组级SRS资源，针对每个SRS资源，用户群组内的所有干扰UE均会在该SRS资源上发送SRS信号，即，第一UE在该SRS资源上接收SRS信号时，该SRS信号是用户群组内的所有干扰UE的SRS累加信号。第一UE基于该SRS资源上的SRS信号确定SRS-RSRP时，该SRS-RSRP是用户群组内的所有干扰UE的SRS信号的累加RSRP值。
对于同一干扰基站下的不同用户群组，可以将不同用户群组的SRS时频资源位置配置成不同。对于不同干扰基站下的用户群组(即不同用户群组)，可以将不同干扰基站下的用户群组的SRS时频资源位置配置成不同。
比如说，若SRS资源是UE级SRS资源，针对每个SRS资源，只有一个干扰UE在该SRS资源上发送SRS信号，即第一UE在该SRS资源上接收SRS信号时，该SRS信号是一个干扰UE的SRS信号。第一UE基于SRS资源上的SRS信号确定SRS-RSRP时，SRS-RSRP是一个干扰UE的SRS信号的RSRP值。
针对UE级SRS资源，对于同一干扰基站下的不同干扰UE，可以为每个干扰UE的SRS配置不同的时频资源位置。对于不同干扰基站下的不同干扰UE，可以为不同干扰基站下的不同干扰UE的SRS配置不同的时频资源位置。
一个例子中，针对上述步骤1，控制器根据各基站的物理位置、帧结构配置和SBFD配置，判断哪些干扰基站对受害基站的受害UE造成CLI干扰，将相应的SRS配置信息下发给每个基站，向基站下发SRS配置信息的过程如下：
在物理位置上与受害基站相邻的基站可能存在干扰UE，并对受害基站中的受害UE产生CLI干扰。若在某一个时刻(时隙或者符号)的全部频域资源或者该时刻的频域子带资源上，受害基站用于DL数据的传输，而其它干扰基站用于UL数据的传输，则相邻基站内的UE可能会存在CLI干扰。
基于上述原理，控制器确定可能存在UE间CLI干扰的基站，为每个基站配置相应的SRS资源，并将SRS配置信息发送给每个基站，即每个干扰基站具有自身的SRS资源配置，也有相邻基站的SRS资源配置，以协调UE进行CLI测量。控制器可以确定SRS资源是Cell-Specific、Group-Common或者UE-Specific。对于Group-Common或者UE-Specific，控制器不会规定服务基站为哪些UE配置这些SRS资源，由服务基站自己来决定为哪些UE配置这些SRS资源。
一个例子中，基站根据SRS配置信息中的基站标识来判断SRS资源是自身服务UE的SRS资源，还是其它基站所服务UE的SRS资源。其中，对于其它基站所服务UE的SRS资源，该基站确定受到CLI干扰的UE，并将SRS配置信息发送给这些UE。其中，配置给UE的其它基站的SRS配置需要添加SRS配置的标识和其它基站的SRS配置信息，详细格式如下所示：

第四、UE-UE的CLI测量结果上报。
一个例子中，干扰UE接收到SRS配置信息后，在相应的SRS资源上发送SRS信号。受害UE接收到SRS配置信息后，在相应的SRS资源上接收SRS信号，对SRS信号进行测量，并得出SRS-RSRP作为CLI测量结果。
一个例子中，对于小区级SRS资源，所有干扰UE会在相同的SRS资源上发送SRS信号，受害UE在该SRS资源上接收所有干扰UE的SRS信号，得出的SRS-RSRP是干扰基站服务的所有干扰UE的SRS信号强度的总和。对于群组级SRS资源，一组干扰UE会在相同的SRS资源上发送SRS信号，受害UE在该SRS资源上接收一组干扰UE的SRS信号，得出的SRS-RSRP是干扰基站服务的一组干扰UE的SRS信号强度的总和。对于UE级SRS资源，干扰UE会在SRS资源上发送SRS信号，受害UE在该SRS资源上接收干扰UE的SRS信号，得出的SRS-RSRP是干扰基站服务的一个干扰UE的SRS信号强度。
一个例子中，对于子带间的CLI测量，受害UE仅需要测量所有干扰信号的RSSI作为CLI测量结果，该CLI测量结果可以包括CLI-RSSI。
一个例子中，CLI测量结果可以包括SRS-RSRP和/或CLI-RSSI，CLI测量结果的上报可以复用CSI(Channel State Information，信道状态信息)上报机制。
比如说，可以对CLI测量结果进行单独上报，第一UE向第一服务基站发送第一上行控制信息(UCI：Uplink Control Information)，第一服务基站接收第一上行控制信息，第一上行控制信息可以用于承载CLI测量结果。对于单独上报，可以为CLI测量结果配置单独的上报资源，即单独的CSI-ReportConfig，该上报配置具有独立标识，并与其它基站的SRS资源配置SRS-ConfigID相关联。
可以对CLI测量结果进行合并上报，第一UE向第一服务基站发送第二上行控制信息，第一服务基站接收第二上行控制信息，第二上行控制信息可以同时用于承载CLI测量结果和除CLI测量结果之外的上行控制信息。除CLI测量结果之外的上行控制信息可以包括SR、ACK、CSI等。对于合并上报，可以在合并上报的CSI-ReportConfig中关联其它基站的SRS资源配置SRS-ConfigID。
针对第一上行控制信息或者第二上行控制信息，第一UE可以通过PUCCH或者PUSCH将第一上行控制信息或者第二上行控制信息上报给第一服务基站。
一个例子中，CLI测量结果的上报类型，可以配置成周期性上报、事件触发上报。针对周期性上报，第一UE根据配置的上报周期上报CLI测量结果。针对事件触发上报，第一UE在达到CLI上报的条件时，上报CLI测量结果。比如说，当测量的SRS-RSRP或者CLI-RSSI超过某一阈值时达到CLI上报的条件。
一个例子中，第一UE可以接收第一服务基站发送的CSI测量配置。若该CSI测量配置包括上报量，且该上报量用于指示上报SRS-RSRP，则第一UE向第一服务基站发送第一UE的CLI测量结果，且CLI测量结果包括SRS-RSRP。
第一UE接收第一服务基站发送的CSI测量配置。若CSI测量配置包括上报量，且上报量用于指示上报SRS-RSRP和CLI-RSSI，则第一UE向第一服务基站发送第一UE的CLI测量结果，且CLI测量结果包括SRS-RSRP和CLI-RSSI。
比如说，CSI上报(CSI测量配置)中需要增加上报量(reportQuantity)以支持CLI的上报。考虑到可能同时存在SRS-RSRP和CLI-RSSI，增加CLI类型的上报量为：SRS-RSRP和SRS-RSRP-CLI-RSSI，前者表示仅存在SRS-RSRP，后者表示在上报RSSI的同时需要上报SRS-RSRP，不单独上报CLI-RSSI。
比如说，与CLI上报配置有关的详细参数如下所示：
一个例子中，CLI测量结果可以包括每个第二服务基站对应的CLI标识、每个SRS资源对应的SRS标识、每个SRS资源对应的SRS-RSRP。
比如说，若SRS配置信息包括K个干扰基站(即第二服务基站)对应的SRS资源，则CLI测量结果包括每个干扰基站中所有SRS资源的SRS-RSRP，每个干扰基站有单独的CLI上报，K个干扰基站有K个CLI上报，将K个CLI上报记为K个子带内干扰测量字段，K个CLI上报与K个第二服务基站一一对应。
针对每个CLI上报，该CLI上报具有唯一的CLI标识，且CLI标识是根据干扰基站的基站标识生成的，并将CLI标识放在CLI上报中。CLI标识所占的字节数大小为ceil(log2(K))，K表示干扰基站的数量。基站标识最小的CLI上报的CLI标识为0，基站标识第二小的CLI上报的CLI标识为1，以此类推。
针对每个CLI上报，该CLI上报中SRS-RSRP的个数与SRS资源数量有关，即每个SRS资源对应一个SRS-RSRP，且每个SRS资源对应一个SRS标识。SRS标识所占字节数大小为ceil(log2(M))，M表示干扰基站中SRS资源的个数。SRS资源标识最小的SRS资源对应的SRS-RSRP的SRS标识为0，SRS资源标识第二小的SRS资源对应的SRS-RSRP的SRS标识为1，以此类推。
综上可以看出，CLI测量结果可以包括每个干扰基站对应的CLI标识、每个SRS资源对应的SRS标识、每个SRS资源对应的SRS-RSRP。
如果受害UE需要测量并上报CLI-RSSI，则CLI测量结果可以包括CLI-RSSI和SRS-RSRP，即CLI-RSSI和SRS-RSRP一起上报。比如说，CLI测量结果可以包括K个子带内干扰测量字段和1个子带间干扰测量字段，且子带间干扰测量字段位于K个子带内干扰测量字段的后面。其中，针对每个子带内干扰测量字段，该子带内干扰测量字段包括干扰基站对应的CLI标识、每个SRS资源对应的SRS标识、每个SRS资源对应的SRS-RSRP。其中，该子带间干扰测量字段可以包括CLI-RSSI，即CLI-RSSI排在最后一个CLI上报的后面。
一个例子中，SRS-RSRP的取值范围可以为[-140,-44]dBm，可以由7位比特定义，步长为1dB，0表示-140dBm，1表示-139dBm，以此类推。CLI-RSSI的取值范围为[-100,-25]dBm，可以由7位比特定义，步长为1dB，0表示-100dBm，1表示-99dBm，以此类推。当然，上述只是示例，对此取值范围不作限制。
一个例子中，CLI测量结果的结构可以参见表2所示。
表2

一个例子中，第一服务基站(即受害基站)在接收到CLI测量结果后，还可以基于CLI标识与基站标识的映射关系(如最小基站标识对应CLI标识0，第二小基站标识对应CLI标识1，以此类推)，确定CLI测量结果中的每个CLI标识对应的基站标识，并通过该基站标识替换CLI测量结果中的CLI标识。这样，第一服务基站可以恢复出CLI测量结果中的CLI上报对应哪个干扰基站，并使用干扰基站的基站标识替换CLI测量结果中的CLI标识。
第一服务基站还可以基于SRS标识与SRS资源标识的映射关系(如最小SRS资源标识对应SRS标识0，第二小SRS资源标识对应SRS标识1)，确定CLI测量结果中的每个SRS标识对应的SRS资源标识，并通过该SRS资源标识替换CLI测量结果中的SRS标识。这样，第一服务基站可以恢复出SRS-RSRP值对应哪个SRS资源，并使用SRS资源标识替换CLI测量结果中的SRS标识。
最后，第一服务基站将CLI测量结果添加上本第一服务基站的基站标识之后，将CLI测量结果发送给控制器，由控制器基于CLI测量结果进行协作调度。
第五、受害UE(即第一UE)的下行调度。
一个例子中，用于CLI测量的SRS资源是配置在受害UE的DL符号或DL时隙中，因此，SRS信号接收和PDSCH数据接收会相互影响。为了保证SRS信号的测量，需要在SRS资源所处的时频资源上选择合适的PDSCH传输策略：
方式1：不进行PDSCH调度。在有SRS资源的时隙中，受害基站不调度任何PDSCH传输，这样，受害UE禁止在该SRS资源所在时隙中接收PDSCH数据，受害UE可以在该SRS资源的位置只接受SRS信号，得出CLI测量结果。
方式2：对PDSCH做速率匹配。在有SRS资源的时隙中，受害基站可以在该SRS资源所在的时隙中对PDSCH数据进行速率匹配，且受害UE可以在该SRS资源所在的时隙中对PDSCH数据进行速率匹配。
比如说，由于SRS资源是资源元素(RE)级别，因此，可以为PDSCH配置RE级别的速率匹配参数。此时，可以将需要被速率匹配的SRS资源集或者SRS资源添加到PDSCH的配置参数PDSCH-Config中，参见如下配置参数：
受害UE在接收到上述配置参数后，即可得知包含在PDSCH的配置参数中的SRS资源不能用于PDSCH。对于非周期性的SRS和半持续的SRS，仅在SRS被激活时，受害UE才执行PDSCH围绕SRS做速率匹配。
对于以上两种方式，在通过DCI调度PDSCH时，受害UE可以获知采用哪种方式进行处理，无需通过特殊的信令来告知受害UE使用哪一种方式。
由以上技术方案可见，在F-TDD系统或者SBFD系统中，UE间的CLI会影响系统整体性能。通过获取UE的CLI测量结果，就可以基于CLI测量结果实现UE间的协作调度，降低UE间的CLI，提高数据传输性能。
一个例子中，控制器向干扰基站和受害基站发送SRS配置信息，干扰基站将SRS配置信息发送给自身服务的干扰UE，受害基站将SRS配置信息发送给自身服务的受害UE。干扰UE根据SRS配置信息发送CLI测量信号(即SRS信号)，受害UE根据SRS配置信息接收并测量SRS信号，得出CLI测量结果。
受害UE将CLI测量结果上报给受害基站，受害基站将CLI测量结果上报给控制器，供控制器基于CLI测量结果进行协作调度。
基于同一发明构思，还提供与CLI测量方法对应的CLI测量装置，及基站和UE，由于基站和UE解决问题的原理与CLI测量方法相似，因此，基站和UE的实施参见CLI测量方法，重复之处不再赘述。
