为更好理解本申请的技术方案，首先对以下内容进行介绍：
灵活双工(Flexible duplex)
在部署传统的蜂窝网络时，基于可用的频谱，以及业务特性等，可采用频分双工(Frequency Division Duplex，FDD)或时分双工(Time Division Duplex，TDD)双工方式。当采用FDD时，上行传输和下行传输位于不同的频点上，两者互不干扰，可同时进行。当采用TDD时，上行传输和下行传输位于同一个频点上，采用时分的方式交错进行。两种双工方式各有优缺点。
为了更灵活地利用有限的频谱资源，以动态地匹配业务需求，提升资源利用效率，以及数据传输的上行覆盖、时延等性能，提出了灵活的双工方式。一种灵活双工方式(non-overlapping subband full duplex，SBFD)为：网络侧全双工，即在同一时刻，上行传输和下行传输可在不同的频域位置同时进行，为避免上下行之间的干扰，可在对应不同传输方向的频域位置(对应双工子带)之间留出一定的防护带(Guard Band)；终端侧半双工，即与TDD一致，在同一时刻，只能作上行传输或下行传输，两者不可同时进行。可以理解的是，在这种网络侧全双工，终端侧半双工的方式下，网络侧在同一时刻的上行传输和下行传输只能针对不同的终端。
例如图1b给出了上述灵活双工方式的示意图，网络侧在一部分下行符号内，将单个载波或带宽部分BWP的频域半静态划分为三个双工子带，其中载波两侧为下行双工子带，中央为上行双工子带，以减少对相邻载波造成的干扰。在第三个时隙内，UE1和UE2分别作上行发送和下行接收。
TDD pattern
当NR小区部署在非对称频谱上时，一般采用TDD双工方式。此时可以在小区公共参数中配置TDD-UL-DL-ConfigCommon，以指示TDD帧结构信息，包括TDD帧周期，单个帧周期内包含的完整下行/上行Slot数目，在完整下行/上行Slot之外额外包含的下行/上行Symbol数目等。可选地，还可以针对各个UE采用RRC信令独立配置TDD-UL-DL-ConfigDedicated，用于在TDD-UL-DL-ConfigCommon的基础上进一步修改单个帧周期内一个或多个Slot的上下行Symbol配置(即Slot的上下行Symbol配置的初始值由TDD-UL-DL-ConfigCommon规定，然后由TDD-UL-DL-ConfigDedicated进一步修改，此修改仅应用于接收此RRC信令的UE)，但这里的修改仅局限于将Slot内的Flexible symbol(即未明确传输方向，后续可根据需要再确定是用于下行传输还是上行传输)进一步指示为下行链路(DownLink，DL)/上行链路(UpLink，UL)symbol，不能将Slot内的DL/UL symbol修改为其它方向。
上述TDD-UL-DL-ConfigCommon和/或TDD-UL-DL-ConfigDedicated为可选配置，由于这些配置信息只能基于RRC层的信息半静态配置/修改，所以由这些配置信息确定的单个TDD帧周期内各个Symbol(结合为其配置的传输方向)，在下文中称之为Semi-static DL/UL/flexible symbol。可以将symbol进一步抽象为时域单元，时域单元可对应时隙(Slot)、符号(Symbol)等，则单个TDD帧周期内可基于上述配置信息包含多个Semi-static DL/UL/flexible时域单元。
当未配置上述TDD-UL-DL-ConfigCommon和TDD-UL-DL-ConfigDedicated时，不存在明确的TDD帧周期的概念，此时NR小区各个无线帧内的各个Slot/Symbol都可以理解为Semi-static flexible slot/symbol，或者抽象为Semi-static flexible时域单元。
另外，基站还可以通过动态信令group common DCI(例如DCI 2-0)指示时隙格式SFI，其中动态SFI仅可以指示Semi-static flexible symbol为DL/UL/flexible，而不能改变Semi-static DL/UL symbol的传输方向。
在动态TDD***中，相邻的小区可以配置不同的TDD配置，或者一个小区内部不同UE有不同的TDD配置或指示。因此会出现相邻小区间gNB到gNB(gNB1在进行下行发送的同时，gNB 2在进行上行接收，对于gNB 2来说，将会收到gNB 1的干扰)或者UE到UE的干扰(UE1在进行上行发送的同时，UE2在进行下行接收，对于UE2来说，将会收到UE1的干扰)。
CLI测量
为了识别出前述UE-to-UE CLI的严重程度，需要进行UE-to-UE干扰测量，一个实例如图1c所示，UE1基于gNB1的调度进行PUSCH传输，同时UE 2基于gNB2的触发进行干扰测量。为了有效的测量UE1发送对UE2的干扰程度，UE 2的干扰测量资源(Interference measurement resource，IMR)是UE 1进行PUSCH发送的全部物理资源，或者部分物理资源(例如图中通过填充示出UE 2的IMR是UE 1进行PUSCH发送的部分物理资源)。现有干扰测量量主要包括基于探测参考信号的参考信号接收功率(Sounding Reference Signal based Reference Signal Received Power，SRS based RSRP)，或者接收信号强度指示(Received Signal Strength Indication，RSSI)等。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的交叉链路干扰处理方法进行详细地说明。
参见图2，本申请实施例提供一种交叉链路干扰处理方法，该方法的执行主体为第一网络设备，方法包括：
步骤201：第一网络设备分配第一资源，第一资源用于第一终端传输上行信号或者调度第一终端下行接收；
步骤202：第一网络设备向第二网络设备发送第一消息，第一消息中包含第一资源的资源标识信息；
步骤203：第一网络设备从第二网络设备接收第二消息，第二消息中包含第一测量结 果或者第二资源的资源标识信息；
步骤204：第一网络设备根据第二消息，执行干扰处理操作；
其中，第一终端是归属于第一网络设备的终端，第一测量结果是第二网络设备或者第二终端对第一资源进行CLI测量得到的测量结果，第二资源是第一测量结果中满足预设阈值的测量结果对应的资源，第二终端是归属于第二网络设备的终端。
在本申请实施例中，第一网络设备分配用于第一终端传输上行信号或者调度第一终端下行接收的第一资源，并通过第一消息将第一资源的资源标识信息发送给第二网络设备，由第二网络设备触发第二网络设备或者第二终端对第一资源的CLI测量，然后第二网络设备通过第二消息将第一测量结果发送给第一网络设备，或者将第一测量结果中满足预设阈值的测量结果对应的第二资源的资源标识信息发送给第一网络设备，由第一网络设备根据这些信息执行干扰处理操作；这样通过第一网络设备与第二网络设备之间的交互，实现针对CLI的干扰处理，同时由于第一网络设备与第二网络设备之间只交互测量结果或者只交互满足一定要求的资源标识信息，在实现干扰协调的同时节省网络设备间交互信息开销。
需要说明的是，上述第二网络设备不等于第一网络设备，或者，第一网络设备和第二网络设备的关系包括如下至少一项：
(1)小区间、站点间gNB-gNB(inter-cell inter-site gNB-gNB)；
(2)小区间同址扇区间gNB-gNB(inter-cell co-site inter-sector gNB-gNB)；
上述第一网络设备分配第一资源，具体可以分配一个或多个资源，具体可以取决于归属于第一网络设备的第一终端的数量；
上述第一终端在第一资源上传输上行信号，该上行信号可以包括但不限于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)信号、物理上行控制信道(Physical Uplink Control Channel，PUCCH)信号、探测参考信号(Sounding Reference Signal，SRS)、物理随机接入信道(Physical Random Access Channel，PRACH)信号、其他上行信号中的一种或多种；
上述第一测量结果具体是第二终端对第一资源中的所有资源进行CLI测量得到的测量结果，即第二消息中包含第一测量结果的情况，具体指的是，第二网络设备将全部第一资源对应的CLI测量结果发送给第一网络设备。需要说明的是，基于全部测量结果能够知道测量结果与测量资源(即第一资源)的对应关系，即对于测量结果以及对应测量资源的映射关系在两个网络设备间是确定的，可以是一一对应，即资源0、资源1、资源2……对应测量结果0、测量结果1、测量结果2……，或者也可以是逆序，又或者也可以是两个网络设备间预先约定好的其他顺序。这样只需将全部的测量结果发送给第一网络设备，第一网络设备即可获知先前分配的每个第一资源对应的CLI情况，进而针对性的进行干扰处理。
上述第二资源是第一测量结果中满足预设阈值的测量结果对应的资源，可以理解的是第二资源实质上是第一网络设备分配的第一资源中的至少部分资源，即第二网络设备根据 第二终端的CLI测量结果，将满足预设阈值的测量结果对应的资源作为第二资源反馈给第一网络设备，这样只反馈CLI比较大的部分资源给第一网络设备，由第一网络针对这部分资源，进行针对性的进行干扰处理。具体地，预设阈值可以是预定义或网络设备配置的，例如上述CLI测量结果为RSRP、RSSI、信道质量指示(Channel quality indicator，CQI)时，可以设置一个第一阈值，如果测量结果大于第一阈值，则将对应的资源归为第二资源；又例如上述CLI测量结果为信号与干扰加噪声比(signal-to-noise and interference ratio，SINR)时，可以设置一个第二阈值，如果测量结果小于第二阈值，则将对应的资源归为第二资源。如果每个测量资源的CLI测量结果包含多个指标，如RSSI和CQI，上述CLI测量结果满足预设阈值可以是每个指标分别满足各自的预设阈值或者至少有一个指标满足其对应的预设阈值。本申请实施例对具体的预设阈值的设置不做限定。
具体地，对于第一资源用于第一终端传输上行信号，相应第一测量结果是第二终端对第一资源进行CLI测量得到的测量结果的情况，主要可以用于解决UE-to-UE的干扰协调；
对于第一资源用于调度第一终端下行接收，相应第一测量结果是第二网络设备对第一资源进行CLI测量得到的测量结果的情况，主要可以用于解决gNB-to-gNB的干扰协调。对于这种情况是第二网络设备进行CLI测量，所以不需要接收第二终端的测量结果。
在一种可能的实施方式中，第一网络设备与第二网络设备之间的交互通过接口或空中下载技术(Over-the-Air Technology，OTA)实现，接口可以为X2接口、Xn接口、S1接口、NG接口或lu接口等，本申请实施例对此不做具体限定。
在一种可能的实施方式中，资源标识信息包括以下一项或者多项：
(1)时域信息，具体体现为如下一种或多种：
(1.1)无线帧号(Radio frame number)；
(1.2)Slot和/或subframe index(es)，可以是一个或多个slot；
(1.3)Symbol、sub-slot index(es)和/或symbol数目，可以是一个或多个symbol，例如一个slot中的最后一个或多个符号；
(1.4)第一上行资源还可以由周期(periodicity)进行标识，也就是第一上行资源在每隔一定周期重复出现，例如以无线帧(10ms)长为periodicity；
(2)频域信息，具体体现为如下一种或多种：
(2.1)频域位置，如PRB index(es)，或子载波位置等，例如如果采用的是梳状结构(comb结构)传输，如SRS，则需要指示comb的位置或index；
(2.2)带宽(Bandwidth，BW)；
(2.3)跳频图样；
(2.4)频率偏移(freqDomainShift)；
(2.5)子载波间隔(Subcarrier Space，SCS)或SCS和CP；
(3)功率信息，例如上行信号发射每个资源单元的能量(Energy per resource element，EPRE)或总的发送功率等；
(4)序列信息，例如SRS序列index，或preamble序列index等；
(5)空间信息，例如空间关联信息(spatial relation information)，或传输配置指示状态(Transmission Configuration Indicator state，TCI state)或者准共址类型D(Quasi co-location-D，QCL-D)，或波束(beam)信息等；
(6)资源索引或资源编号，其中一个资源索引或资源编号可以对应一个或多个资源，例如一个资源索引或资源编号对应一组第一资源的资源标识，第二网络设备向第一网络设备通知第一资源时，可以直接发送第一资源的编号。可以理解的是，第一网络设备向第二网络设备发送第一资源的资源标识信息时，不仅发送资源ID，还发送时频域等具体信息，这样第二网络设备能够让第二终端在这些资源上进行CLI测量。而第二网络设备将测量结果反馈给第一网络设备时，可以只发送资源ID，不需要发送时频域等信息，因为这些信息是第一网络设备发送给第二网络设备的，第一网络设备只要通过资源ID就能够知道具体资源信息。
需要说明的是，该资源标识信息对于上述第一资源和第二资源是通用的(因为第二资源是第一资源中的部分资源，本质上也是第一资源，即第一网络设备分配的用于第一终端传输上行信号的资源)，这样通过上述资源标识信息即可获知具体的通信资源。
在一种可能的实施方式中，第一消息中还包含以下一项或者多项：
(1)第一终端的服务小区的信息,例如物理小区标识(Physical Cell Identifier，PCI)、小区全球标识符(Cell Global Identifier，CGI)、E-UTRAN小区全局标识(E-UTRAN Cell Global Identifier，ECGI)或NR小区全球标识符(NR-Cell Global Identifier，NR-CGI)；服务小区的信息主要是为了标识不同的服务小区；
(2)几乎空白子帧(Almost blank subframe，ABS)的信息。ABS信息是为了干扰协调，第二网络设备如果在ABS上调度第二终端，则可以避免来自第一网络设备的干扰。
在一种可能的实施方式中，在第二消息中包含第一测量结果的情况下，第一网络设备根据第二消息，执行干扰处理操作，包括：
(1)第一网络设备从第一测量结果中确定出满足预设阈值的第二测量结果；
在本申请实施例中，第一网络设备从第二网络设备接收第二终端对全部第一资源进行CLI测量得到的测量结果，然后根据预设阈值，从第一测量结果中筛选出部分测量结果，即第二测量结果。具体地第二测量结果可以是能够反映出CLI比较大的测量结果。
(2)第一网络设备根据第二测量结果对应的第一资源的资源标识信息，确定出目标资源；
在本申请实施例中，第一网络设备根据筛选出的第二测量结果确定出对应的第一资源的资源标识信息，根据确定出的资源标识信息确定出目标资源，可以理解为第一终端在该目标资源上传输上行信号所产生的CLI比较大。
(3)第一网络设备根据目标资源，在第一终端中确定出目标终端；
在本申请实施例中，第一网络设备根据确定出目标资源，从所有归属于第一网络设备 的第一终端中确定出目标终端，即确定出在目标资源上传输上行信号产生较大CLI的终端。
(4)第一网络设备对目标终端执行干扰处理操作。
在本申请实施例中，第一网络设备针对确定出的目标终端进行干扰处理操作，具体地，目标终端为在目标资源上已被调度的一个或多个终端，第一网络设备可以确定出一个终端集合，该集合中包含所有确定出的目标终端，第一网络设备对该终端集合中的至少部分终端进行干扰处理操作。在一些实施场景中，如果是多个终端在目标资源上传输信号产生的CLI较大，第一网络设备停止其中部分终端的上行传输，也可以减少CLI。
在一种可能的实施方式中，在第二消息中包含第二资源的资源标识信息的情况下，第一网络设备根据第二消息，执行干扰处理操作，包括：
(1)第一网络设备根据第二资源的资源标识信息，在第一终端中确定出目标终端；
在本申请实施中，由于第二资源已经是根据满足预设阈值的测量结果而筛选出的资源，即第二资源已经是确定出的与产生较大CLI相关的资源，因此第一网络设备直接根据该第一资源的资源标识信息，从所有归属于第一网络设备的第一终端中确定出目标终端，以及将使用第二资源传输上行信号的第一终端确定为目标终端。
(2)第一网络设备对目标终端执行干扰处理操作。
在本申请实施例中，第一网络设备针对确定出的目标终端进行干扰处理操作，具体地，目标终端为在目标资源上已被调度的一个或多个终端，第一网络设备可以确定出一个终端集合，该集合中包含所有确定出的目标终端，第一网络设备对该终端集合中的至少部分终端进行干扰处理操作。
在一种可能的实施方式中，执行干扰处理操作包括：
在所述第二网络设备执行下行传输的时间段内，基于所述目标终端，执行以下一项或者多项：
(1)停止或减少调度终端传输上行信号；可选地，第一网络设备仅在第二网络设备存在下行传输的时间段内，执行上述减少或避免调度的操作。
(2)减少或降低终端传输上行信号的传输功率；
(3)调度终端传输上行信号时采用与历史调度不同的空间关系，该历史调度具体指第一网络设备在上述测量资源(具体为上述第二资源)对应的位置进行的调度；
(4)第一网络设备向第二网络设备发送干扰协调请求消息，干扰协调请求消息中包含期望的上下行配置(Intended UL-DL Configuration)，和/或，期望的协调信息(Intended coordination information)。可选地，期望的协调信息具体可以是期望的上行子帧(Intended UL subframe(s))。
在一种可能的实施方式中，在第二网络设备采用中心单元(central unit，CU)与分布单元(distributed unit，DU)分离架构的情况下，
第一网络设备向第二网络设备发送第一消息，包括：第一网络设备向第二网络设备的CU发送第一消息；
第一网络设备从第二网络设备接收第二消息，包括：第一网络设备从第二网络设备的CU接收第二消息。
参见图3，本申请实施例提供一种交叉链路干扰处理方法，该方法的执行主体为第二网络设备，方法包括：
步骤301：第二网络设备从第一网络设备接收第一消息，第一消息中包含第一资源的资源标识信息，第一资源由第一网络设备分配，用于第一终端传输上行信号或者调度第一终端下行接收；
步骤302：第二网络设备触发第二网络设备或者第二终端对第一资源进行CLI测量；
步骤303：第二网络设备从第二终端接收第一测量结果，第一测量结果是第二网络设备或者第二终端对第一资源进行CLI测量得到的测量结果；
步骤304：第二网络设备向第一网络设备发送第二消息，第二消息中包含第一测量结果或者第二资源的资源标识信息；
其中，第一终端是归属于第一网络设备的终端，第二资源是第一测量结果中满足预设阈值的测量结果对应的资源，第二终端是归属于第二网络设备的终端。
在本申请实施例中，第一网络设备分配用于第一终端传输上行信号或者调度第一终端下行接收的第一资源，并通过第一消息将第一资源的资源标识信息发送给第二网络设备，由第二网络设备触发第二网络设备或者第二终端对第一资源的CLI测量，然后第二网络设备通过第二消息将第一测量结果发送给第一网络设备，或者将第一测量结果中满足预设阈值的测量结果对应的第二资源的资源标识信息发送给第一网络设备，由第一网络设备根据这些信息执行干扰处理操作；这样通过第一网络设备与第二网络设备之间的交互，实现针对CLI的干扰处理，同时由于第一网络设备与第二网络设备之间只交互测量结果或者只交互满足一定要求的资源标识信息，在实现干扰协调的同时节省网络设备间交互信息开销。

(4)序列信息，例如SRS序列index，或preamble序列index等；
(5)空间信息，例如空间关联信息(spatial relation information)，或TCI state或者QCL-D或波束信息；
(6)资源索引或资源编号，其中一个资源索引或资源编号可以对应一个或多个资源，例如一个资源索引或资源编号对应一组第一资源的资源标识，第二网络设备向第一网络设备通知第一资源时，直接发送第一资源的编号。可以理解的是，第一网络设备向第二网络设备发送第一资源的资源标识信息时，不仅发送资源ID，还发送时频域等具体信息，这样第二网络设备能够让第二终端在这些资源上进行CLI测量。而第二网络设备将测量结果反馈给第一网络设备时，可以只发送资源ID，不需要发送时频域等信息，因为这些信息是第一网络设备发送给第二网络设备的，第一网络设备只要通过资源ID就能够知道具体资源信息。
需要说明的是，该资源标识信息对于上述第一资源和第二资源是通用的(因为第二资源是第一资源中的部分资源，本质上也是第一资源，即第一网络设备分配的用于第一终端传输上行信号的资源)，这样通过上述资源标识信息即可获知具体的通信资源。
在一种可能的实施方式中，第一消息中还包含以下一项或者多项：
(1)第一终端的服务小区的信息,例如PCI、CGI、ECGI或NR-CGI；服务小区的信息主要是为了标识不同的服务小区；
(2)ABS的信息。ABS信息是为了干扰协调，第二网络设备如果在ABS上调度第二终端，则可以避免来自第一网络设备的干扰。
在一种可能的实施方式中，第二网络设备触发第二终端进行CLI测量和上报，具体测量方式包括但不限于如下中的一种或多种：
(1)RSRP测量：第二终端在第一资源上进行RSRP测量，例如当第一资源上的第一终端发送信号为SRS时，测量SRS-based RSRP；又例如当第一资源上的第一终端发送信号为PRACH时，测量preamble-based RSRP；
(2)RSSI测量；第二终端在第一资源上进行RSSI测量，RSSI测量行为与第一资源上第一终端发送的具体信号无关；
(3)CQI测量：第二终端在第一资源上进行干扰测量，并结合在其他资源(如CSI-RS)上测量到的信号测量结果，联合处理计算CQI；
(4)SINR测量：第二终端在第一上行资源上进行干扰测量，并结合其他资源(如CSI-RS)上测量到的信号测量结果，联合处理计算SINR；
在一种可能的实施方式中，第二网络设备告知第二终端进行上述一种或多种测量的资 源，该资源包括第一资源中的部分或全部资源，其中：
(1)第二网络设备在触发第二终端进行测量前，将测量资源告知第二终端，或者
(2)第二网络设备触发第二终端进行CLI测量时，直接指示干扰测量的物理资源(时域、频域和/或序列信息)；
在一种可能的实施方式中，第二终端向第二基站上报CLI测量结果，测量结果为上述测量量中的至少一个；
可选的，第二终端还向第二基站上报进行干扰测量所使用的干扰测量资源信息。
在一种可能的实施方式中，在第二消息中包含第二资源的资源标识信息的情况下，第二网络设备向第一网络设备发送第二消息，包括：
(1)第二网络设备从第一测量结果中确定出满足预设阈值的第二测量结果；
在本申请实施例中，第二网络设备接收第二终端对全部第一资源进行CLI测量得到的测量结果，然后根据预设阈值，从第一测量结果中筛选出部分测量结果，即第二测量结果。具体地第二测量结果可以是能够反映出CLI比较大的测量结果。
(2)第二网络设备根据第二测量结果对应的资源标识信息，确定出第二资源；
在本申请实施例中，第二网络设备根据筛选出的第二测量结果确定出对应的第一资源的资源标识信息，根据确定出的资源标识信息确定出第二资源，可以理解为第一终端在该第二资源上传输上行信号所产生的CLI比较大。
(3)第二网络设备通过第二消息向第一网络设备发送第二资源的资源标识信息。
在一种可能的实施方式中，方法还包括：
第二网络设备从第一网络设备接收干扰协调请求消息，干扰协调请求消息中包含期望的上下行配置，和/或，期望的协调信息。
