Description

一种CLI的测量方法及通信装置
相关申请的交叉引用
本申请要求在2021年06月11日提交国家知识产权局、申请号为202110653933.0、申请名称为“一种CLI的测量方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及干扰测量技术领域，尤其涉及一种交叉链路干扰(Cross-link Interference，CLI)的测量方法及通信装置。
背景技术
时分双工(time division duplexing，TDD)是通过时分来实现上行和下行传输的双工方式。在TDD通信模式下，通信系统中的接收和发送是在同一频率的不同时间内进行的。当相邻小区之间的TDD上下行配比(TDD UL/DL pattern)不同时，一个小区内的发送数据可能会对另一个小区内的接收数据产生干扰，这种干扰称为交叉链路干扰(cross link interference，CLI)。
为了减少或避免CLI，网络设备会为终端设备配置用于测量CLI的资源，用于终端设备测量CLI。网络设备根据终端设备的测量结果协调调度终端设备使用的资源。然而如果网络设备为终端设备配置的用于测量CLI的资源中的部分或者全部资源，又被指示用于其他用途，终端设备无法确定网络设备配置的用于测量CLI的资源的用途，会造成通信异常。
发明内容
本申请提供一种CLI的测量方法及通信装置，用于明确终端设备测量CLI的条件，以尽量减少通信异常。
第一方面，提供了一种通信方法，该方法包括：
终端设备接收来自网络设备的资源配置信息，该资源配置信息用于指示终端设备测量CLI的第一资源；当满足第一特定条件，终端设备在至少一个符号上取消测量CLI，其中，至少一个符号包括第一资源所在的符号。该方案通过明确终端设备取消测量CLI的特定条件，可避免终端设备在配置的测量CLI资源发生冲突的情况下造成的通信异常问题。
一种可能的实现方式中，至少一个符号包括第一资源所在的符号以及第一资源所在的符号之前的N0个符号，所述N0为正整数。即N0为大于或等于1的整数。由于终端设备到终端设备之间的距离通常小于终端设备到网络设备之间的距离，那么例如第一终端设备到第二终端设备的信号相比网络设备到第二终端设备的信号来说，会提前到达第二终端设备。因此，终端设备会提前测量CLI。即终端设备实际用于测量CLI的符号为第一资源所在的符号以及第一资源所在的符号之前的N0个符号。该方案中，满足第一特定条件，终端设备除了在第一资源所在的符号上取消测量CLI，也取消在所述N0个符号上测量CLI，以尽量避免用于测量CLI的资源发生冲突。
一种可能的实现方式中，第一特定条件包括以下几种条件中的一种或多种：
条件一，至少一个符号与第二资源所在的符号部分或全部重叠，该第二资源所在的符号为上行符号。由于至少一个符号被用于测量CLI，当至少一个符号与第二资源所在的上行符号部分或全部重叠，也就是用于测量CLI的至少一个符号中的部分符号或全部符号既用于下行传输时，又用于上行传输。这种情况下，终端设备在至少一个符号上取消测量CLI。即当用于测量CLI的资源与用于上行传输的资源部分或全部重叠时，为了避免所述至少一个符号发生冲突，终端设备取消测量CLI。
一种可选的实现方式中，第二资源所在的符号可由无线资源控制(radio resource control，RRC)信令配置为上行符号。或者，第二资源所在的符号也可由时隙格式指示(slot format indicator，SFI)指示为上行符号。
条件二，至少一个符号与第三资源部分或全部重叠，第三资源包括一个或多个有效的物理随机接入信道(physical random access channel，PRACH)时机所在的符号。或者，第三资源包括一个或多个有效的PRACH时机所在的符号，以及所述一个或多个有效的PRACH时机之前的N gap个符号中的至少一个符号，所述N gap为大于或等于0的整数。
由于一个或多个有效的PRACH时机所在的符号应当为上行符号或灵活符号，一个或多个有效的PRACH时机之前的N gap个符号应当为上行符号或灵活符号。终端设备在至少一个符号上测量CLI，终端设备认为至少一个符号为下行符号。因此，当至少一个符号与第三资源部分或全部重叠，也就是至少一个符号存在冲突，终端设备取消测量CLI，以避免影响有效PRACH时机上信号的发送。
条件三，至少一个符号中的一个或多个符号由下行控制信息(dowlink control information，DCI)指示用于发送上行信号或接收下行信号。
当用于测量CLI的资源与DCI调度的上行信号或DCI指示的下行信号所在的资源在时域上存在一个或多符号重叠时，用于CLI的资源优先用于发送DCI调度的上行信号或接收DCI指示的下行信号。
一种可选的实现方式中，所述第一资源由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由DCI指示用于发送上行信号，终端设备取消测量CLI。
一种可选的实现方式中，所述第一资源由DCI指示用于测量CLI，所述至少一个符号中的一个或多个符号由DCI指示用于发送上行信号。终端设备不希望这种情况出现，当这种情况出现，终端设备取消测量CLI。
一种可选的实现方式中，所述至少一个符号与第四资源所在的符号部分或全部重叠，且第四资源所在的子载波和至少一个子载波部分或全部重叠，其中，所述至少一个子载波包括所述第一资源所在的子载波。例如，所述第一资源由RRC配置用于测量CLI，且所述第四资源由DCI指示用于接收下行信号，终端设备取消测量CLI。又例如，所述至少一个符号由DCI指示用于测量CLI，且所述第四资源由DCI指示用于接收下行信号。终端设备不希望这种情况出现，当这种情况出现，终端设备取消测量CLI。
一种可能的实现方式中，所述第一资源由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由RRC配置发送上行信号或接收下行信号。或者，所述至少一个符号由DCI指示用于测量CLI，所述至少一个符号中的一个或多个符号由RRC配置发送上行信号或接收下行信号。终端设备也不希望这些情况出现，当这些情况出现，终端设备取消测量CLI。
条件四，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号或RRC没有配置所述至少一个符号的类型，且所述至少一个符号有SFI配置，终端设备未检测到SFI，终端设备未检测到DCI指示在所述第一资源测量CLI。或者，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号或RRC没有配置所述至少一个符号的类型，终端设备检测到SFI指示所述至少一个符号中的一个或多个符号为灵活符号，终端设备未检测到DCI指示在所述第一资源测量CLI。
该方案中，尽管网络设备为终端设备配置了用于测量CLI的第一资源，但是网络设备通过RRC配置所述至少一个符号中的一个或多个符号为灵活符号，或者，网络设备并没有明确配置所述至少一个符号为上行符号或下行符号或灵活符号。在所述至少一个符号有SFI配置，终端设备未检测到SFI时，终端设备可认为所述至少一个符号中的一个或多个符号的方向未配置。在终端设备检测到SFI指示所述至少一个符号中的一个或多个符号为灵活符号时，终端设备认为这些符号为保留符号。这种情况下，如果没有DCI指示终端设备在第一资源上测量CLI，终端设备不在至少一个符号上测量CLI，这样可避免终端设备在至少一个符号上测量CLI与使用至少一个符号发送上行信号或接收下行信号发生冲突。
条件五，终端设备配置有多个服务小区，这多个服务小区包括参考小区和其他小区，所述其他小区为所述服务小区中除参考小区之外的服务小区，至少一个符号在参考小区的传输方向与至少一个符号在其他小区的传输方向不同。
一种可能的实现方式中，第一资源在参考小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在其他小区由DCI指示用于发送上行信号或接收下行信号。该方案中，假设第一资源在参考小区用于测量CLI。由于所述至少一个符号中的一个或多个符号在其他小区由DCI指示用于发送上行信号或接收下行信号，即既用于测量CLI又用于发送上行信号或接收下行信号，例如物理下行共享信道(physical downlink shared channel，PDSCH)，物理下行控制信道(physical downlink control channel，PDCCH)或信道状态信息参考信号(channel state information reference signal，CSI-RS)，为了避免所述至少一个符号发生冲突，终端设备取消测量CLI。
条件五也可为：第一资源在其他小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在参考小区由RRC配置为上行符号。如果第一资源在参考小区用于测量CLI，但是所述至少一个符号中的一个或多个符号在其他小区被配置为上行符号，还是可能会发生冲突。为了避免所述至少一个符号发生冲突，终端设备取消测量CLI。
条件五还可以为：第一资源在其他小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在参考小区由RRC配置为用于发送上行信号或接收下行的符号。为了避免所述至少一个符号发生冲突，终端设备取消测量CLI。
作为一种可选的实现方式，条件四中，第一资源所在的符号在参考小区对应的频段与第一资源所在的符号在其他小区对应的频段可以相同，也可以不相同。
作为一种可选的实现方式，第一资源在服务小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在参考小区和其他小区的传输方向不同。例如，所述至少一个符号在参考小区由RRC配置为下行符号，所述至少一个符号中的一个或多个符号在其他小区由RRC配置为上行符号。又例如，所述至少一个符号在参考小区由RRC配置为上行符号，所述至少一个符号中的一个或多个符号在其他小区由RRC配置为下行符号。该实现方式下，参考小区的频段与其他小区的频段不同。如果符号在参考小区和其他小区的 方向不同，终端设备可认为该符号为灵活符号，不要求终端设备接收下行信号，也不期望在该符号发送上行信号。因此，至少一个符号中的一个或多个符号在参考小区和其他小区的传输方向不同，终端设备可取消测量CLI。
作为一种可选的实现方式，终端设备满足如下四种特性中的一种或多种：终端设备支持半双工模式，且终端设备配置有多个服务小区；终端设备不支持在任意服务小区中同时发送和接收；终端设备具有非成对频谱载波聚合(carrier aggregation，CA)的半双工能力；终端设备在任意一个服务小区中没有SFI配置。该方案中，对终端设备作了一些限制，例如终端设备支持半双工模式，即终端设备不能同时发送和接收。又例如，如果终端设备在任意服务小区没有SFI配置，可认为服务小区中的符号的传输方向通过RRC配置。也就是服务小区中的符号的传输方向已经被配置了。这些情况下，当至少一个符号中的一个或多个符号被用于例如发送上行信号，会发生资源冲突，终端设备取消测量CLI，以优先发送上行信号或接收下行信号。如果终端设备不满足如上的特性，可能不会发生资源冲突，终端设备可按照网络设备的配置测量CLI。
第二方面，提供了另一种测量CLI方法，该方法包括：
接收来自网络设备的资源配置信息，该资源配置信息用于指示终端设备测量CLI的第一资源；当满足第二特定条件，在至少一个符号上测量CLI。至少一个符号包括第一资源所在的符号，或者，至少一个符号包括第一资源所在的符号以及第一资源所在符号之前的N0个符号。考虑到网络设备可以通过DCI指示用于测量CLI的资源，但是所述至少一个符号也可能会由SFI指示具体的类型，这种情况下，用于测量CLI的资源可能发生冲突。该方案进一步明确终端设备测量CLI的特定条件，以避免所述至少一个符号发生冲突，进而尽量避免终端设备的通信异常。
一种可能的实现方式中，第二特定条件包括但不限于以下几种条件的一种或多种：
条件一，第一资源由RRC配置用于测量CLI，所述至少一个符号由RRC配置为下行符号。这种情况下，终端设备即使在所述至少一个符号上测量CLI，也不会引起至少一个符号的冲突。
条件二，第一资源由RRC配置用于测量CLI，所述至少一个符号中一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号由RRC配置为下行符号，且所述终端设备未配置SFI，所述终端设备未检测到DCI指示在所述至少一个符号中的一个或多个符号上发送上行信号或接收下行信号。该条件下，所述至少一个符号中的一个或多个符号为灵活符号，所述至少一个符号除灵活符号之外的符号为下行符号。如果终端设备未配置SFI，那么所述至少一个符号的方向不会被SFI改变。进一步的，终端设备未检测到DCI指示在所述至少一个符号中的一个或多个符号发送上行信号或接收下行信号，那么所述至少一个符号不是上行符号。因此，终端设备可认为所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件三，第一资源由RRC配置用于测量CLI，RRC没有配置所述至少一个符号的类型，且所述终端设备未配置SFI，且所述终端未检测到DCI指示在所述至少一个符号中的一个或多个符号上发送上行信号或接收下行信号。由于至少一个符号没有明确规定是何种类型的符号，那么至少一个符号可作为下行符号，也可以作为上行符号。如果所述终端设备未配置SFI，那么所述至少一个符号的方向不会被SFI改变。进一步的，终端设备未检 测到DCI指示在所述至少一个符号中的一个或多个符号发送上行信号或接收下行信号，那么所述至少一个符号不是上行符号，所述至少一个符号中的一个或多个符号没有与下行信号重叠。因此，终端设备可认为所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件四，第一资源由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号为由RRC配置为下行符号，且终端设备检测到SFI指示所述至少一个符号中的灵活符号为下行符号。或者，第一资源由RRC配置用于测量CLI，RRC没有配置所述至少一个符号的类型，且终端设备检测到SFI指示所述至少一个符号为下行符号。也就是，第一资源由RRC配置用于测量CLI，所述至少一个符号中除被RRC配置为灵活符号之外的符号由RRC配置为下行符号，且终端设备检测到SFI指示所述至少一个符号中的灵活符号为下行符号。或者，第一资源由RRC配置用于测量CLI，RRC没有配置所述至少一个符号的类型，且终端设备检测到SFI指示所述至少一个符号中的灵活符号为下行符号。与条件二或条件三类似，即如果所述至少一个符号中的一个或多个符号为灵活符号，第一资源所在的符号没有明确规定是何种类型的符号，那么第一资源所在的符号可作为下行符号，也可以作为上行符号。然而SFI指示所述至少一个符号为下行符号，那么终端设备明确所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件五，所述至少一个符号由RRC配置为下行符号，所述终端设备检测到DCI指示在所述第一资源测量CLI。该条件下，如果所述至少一个符号由RRC配置为下行符号，那么终端设备明确所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件六，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号为由RRC配置为下行符号，终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号没有SFI配置。或者，RRC没有配置所述至少一个符号的类型，且终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号没有SFI配置。该条件下，所述至少一个符号中的一个或多个符号为灵活符号，或者所述至少一个符号的类型未配置。灵活符号或者类型未配置的符号可用于接收下行信号，也可以用于发送上行信号。如果所述终端设备未配置SFI，那么所述至少一个符号的方向不会被SFI改变。进一步的，DCI指示终端设备测量CLI，终端设备可以认为所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起所述至少一个符号的冲突。
条件七，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号为由RRC配置为下行符号，终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号有SFI配置，终端设备未检测到SFI或者终端设备检测到SFI指示所述至少一个符号为灵活符号或下行符号。或者，RRC没有配置所述至少一个符号的类型，终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号有SFI配置，终端设备未检测到SFI或者终端设备检测到SFI指示所述至少一个符号为灵活符号或下行符号。相较于条件六来说，如果所述至少一个符号有SFI配置，但是终端设备未检测到SFI，DCI指示终端设备测量CLI，终端设备可以认为所述至少一个符号为下行符号。或者，终端设备检测到SFI指示所述至少一个符号为灵活符号或下行符号，根 据SFI指示及DCI指示测量CLI，终端设备可以认为所述至少一个符号为下行符号。终端设备可在所述至少一个符号上测量CLI，不会引起所述至少一个符号的冲突。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
本申请的实施例提供的技术方案可以应用于第五代(the fifth generation，5G)移动通信系统，例如新无线(new radio，NR)系统，或者应用于长期演进(long term evolution，LTE)系统中，或者还可以应用于下一代移动通信系统或其他类似的通信系统，具体的不做限制。
请参考图1，为本申请实施例适用的通信系统的一示例性的架构图，该通信系统可包括至少一个网络设备和至少一个终端设备。如图1以至少一个网络设备是两个网络设备为例，这两个网络设备分别为网络设备1和网络设备2。每个网络设备覆盖范围内可包括至少一个终端设备，例如网络设备1覆盖终端设备1，网络设备2覆盖终端设备2和终端设备3。需要说明的是，图1只是示意，本申请的实施例对该通信系统中包括的网络设备和终端设备的数量不做限定。在一些实施例中，该通信系统还可以包括其它网络设备，例如无线中继设备、无线回传设备等。
其中，网络设备是终端设备通过无线方式接入到该移动通信系统中的接入设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)。网络设备也可以是指在空口与终端通信的设备，例如其它可能的终端装置。网络设备可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)；或者也可以包括5G NR系统中的下一代节点B(next generation node B，gNB)；或者也可以包括无线保真(wIreless-fIdelity，Wi-Fi)系统中的接入节点等；或者网络设备可以为中继站、车载设备以及未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)设备、设备到设备(device-to-device，D2D)网络中的设备、机器到机器(machine to machine，M2M)网络中的设备、物联网(internet of things，IoT)网络中的设备或者其他网络PLMN网络中的网络设备等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。举例来说，图1中的网络设备1或网络设备2可以是基站，在不同的系统对应不同的设备，例如图1中的网络设备1或网络设备2在第四代移动通信技术(the fourth generation，4G)系统中可以对应eNB，在5G系统中对应gNB。且本申请实施例中的网络设备可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，多个DU可以由 一个CU集中控制。CU和DU可以根据其具备的无线网络的协议层功能进行划分，例如分组数据汇聚协议(packet data convergence protocol，PDCP)层及以上协议层的功能设置在CU，PDCP以下的协议层，例如无线链路控制层(radio link control，RLC)层和介质访问控制(medium access control，MAC)层等的功能设置在DU。需要说明的是，这种协议层的划分仅仅是一种举例，还可以在其它协议层划分。射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，本申请实施例不作任何限制。另外，在一些实施例中，还可以将CU的控制面(control plan，CP)和用户面(user plan，UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。在该网络架构中，CU产生的信令可以通过DU发送给UE，或者UE产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给UE或CU。在该网络架构中，将CU划分为作为RAN侧的网络设备，此外，也可以将CU划分作为CN侧的网络设备，本申请对此不做限制。
终端设备，可以简称为终端，也称为用户设备(user equipment，UE)，是一种具有无线收发功能的设备，可以向网络设备发送信号，或接收来自网络设备的信号。所述终端设备可以是手机、平板电脑、带无线收发功能的电脑、虚拟现实终端设备、增强现实终端设备、工业控制中的无线终端设备、无人驾驶中的无线终端设备、远程医疗中的无线终端设备、智能电网中的无线终端设备、运输安全中的无线终端设备、智慧城市中的无线终端设备、智慧家庭中的无线终端设备。终端设备也可以是固定的或者移动的。本申请实施例对此并不限定。

另外，本申请实施例中，终端设备可以是指用于实现终端的功能的装置，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中。例如终端设备也可以是车辆探测器、加油站中的传感器。
如上介绍了本申请实施例可适用的网络架构，下面介绍与本申请实施例有关的技术特征。
随着业务多样化，同一网络设备在不同时间段也会存在不同的业务需求。以图1为例，网络设备1在上午时间段的业务数据量较多，在下午时间段的业务数据量较少。相较于下午时间段，在上午时间段，网络设备1可为终端设备1配置更多的资源。不同网络设备在相同或不同时间段会存在不同的业务需求。以图1为例，在同一时间段，网络设备1向终端设备1发送数据，网络设备2接收来自终端设备2和/或终端设备3的数据。为了提高频谱的利用率，网络设备1和网络设备2可采用相同的频谱资源。例如对于某个资源，网络设备1可配置为下行资源，网络设备2可配置为上行资源。需要说明的是，上行和下行是 相对而言的，本申请实施例中，将网络设备到终端设备称为下行，将终端设备到网络设备称为下行。另外，资源也可以理解为时频资源，可包括时域资源，也可以包括频率资源。
然而，不同的网络设备共享相同资源可能会引起CLI。举例来说，以时隙m为例，网络设备1可配置时隙m为下行时隙，网络设备2可配置时隙m为上行时隙。也就是，网络设备1在时隙m发送下行信号给终端设备1，终端设备2和终端设备3在时隙m发送上行信号给网络设备2。但是对于网络设备2来说，在时隙m上，除了接收来自终端设备2和终端设备3的上行信号，还可能接收来自网络设备1的下行信号。即对于网络设备2来说，网络设备1发送的下行信号会引起对终端设备2和终端设备2的上行信号的干扰。由于网络设备1对网络设备2引起干扰，所以这种干扰也可以称为网络设备-网络设备之间的干扰(在本文中简称为网络设备间干扰)。同理，对于终端设备1来说，在时隙m上，除了接收来自网络设备1的下行信号，还可能接收来自终端设备2和/或终端设备3的上行信号。即对于终端设备1来说，终端设备2和/或终端设备3发送的上行信号会引起对网络设备1的下行信号的干扰。由于终端设备2和/或终端设备3对终端设备1引起干扰，所以这种干扰也可称为终端设备-终端设备之间的干扰(在本文中简称为终端设备间干扰)。本申请中，将不同网络设备之间的干扰和不同终端设备之间干扰均称为CLI。
本申请实施例主要针对终端设备间的干扰测量CLI为例。因此，在下文中，对网络设备间的干扰测量不多作介绍。为了避免或减少CLI，网络设备会为终端设备配置用于测量CLI的资源，终端设备会在网络设备配置的测量CLI的资源上测量CLI。终端设备测量CLI后，可将获得的测量CLI结果发送给网络设备，网络设备根据该测量CLI结果协调调度，以避免或减少CLI对网络的吞吐量等性能的影响。
根据CLI衡量指标的不同，测量CLI可分如下两种类型，下面分别介绍。
1)信道探测参考信号(sounding reference signal，SRS)-参考信号接收功率(Reference Signal Receive Power，RSRP)测量。
该类型的测量CLI中，参考信号为SRS资源。终端设备测量一个或多个产生干扰的终端设备发送的SRS资源，获得各个SRS资源的RSRP结果，即终端设备可分别测量获得各个干扰源的干扰强度。以图1为例，网络设备2可为终端设备2和终端设备3分别配置一个或多个SRS资源。终端设备2和终端设备3在配置的SRS资源上向网络设备2发送SRS。网络设备1可为终端设备1配置用于接收来自终端设备2和终端设备3发送的SRS的SRS资源。也就是，在该SRS资源上，终端设备1不接收来自网络设备1的下行信号，而是接收终端设备2和终端设备3发送的SRS。该SRS可用于网络设备1下的终端设备1进行不同终端设备之间的测量CLI。需要说明的是，网络设备2为终端设备2和终端设备3可配置不同的SRS资源，这样各个终端设备可通过测量知道各个终端设备的CLI。例如，网络设备2为终端设备2配置SRS资源1，为终端设备3配置SRS资源2。终端设备2在SRS资源1上发送SRS，终端设备3在SRS资源2上发送SRS。终端设备1对在SRS资源1上接收的SRS测量RSRP，获得RSRP测量结果，以确定终端设备2与终端设备1之间的CLI。终端设备1对在SRS资源2上接收的SRS测量RSRP，获得RSRP测量结果，以确定终端设备3与终端设备1之间的CLI。
2)CLI-接收信号强度指示(received signal strength indicator，RSSI)测量，即测量CLI的RSSI。
在该类型的测量CLI中，终端设备在配置的CLI-RSSI测量资源上测量总的接收功率 值。网络设备通过终端设备测量得到的总的接收功率值来判断终端设备总体的受干扰情况如何。以图1为例，网络设备1可为终端设备1配置用于终端设备2和终端设备3引起的CLI的RSSI测量的资源。终端设备1可以测量该资源上的CLI的RSSI。由于该资源上，网络设备2没有对终端设备2和终端设备3的信号有规定，所以，终端设备1无法获得网络设备2下，不同终端设备引起的终端设备间CLI的RSSI，即无法区分终端设备2与终端设备1之间的CLI的RSSI，终端设备3与终端设备1之间的CLI的RSSI。
无论是SRS-RSRP测量，还是CLI-RSSI测量都涉及网络设备为终端设备配置用于测量CLI的资源。为了便于描述，下文中，将用于测量CLI的资源统称为测量CLI资源。沿用图1，网络设备1可通过高层信令，例如无线资源控制(radio resource control，RRC)信令或下行控制信息(downlink control information，DCI)为终端设备1配置测量CLI资源。由于终端设备到网络设备的距离通常比终端设备到终端设备之间的距离长，那么某个终端设备发送的信号到达另一终端设备的时间比到达网络设备的时间短。因此，协议中规定，终端设备测量CLI的起始时间相对于下行链路参考时间需要至少提前N0个符号。N0的取值和测量CLI资源所处的频率范围(Frequency Range，FR)及子载波间隔(Subcarrier Spacing,SCS)有关，如下表1。
表1
SCS(△f) FR1(频率范围1) FR2(频率范围2)
15/30kHz 1 -(该频段不包含此SCS)
60kHz 2 1
120kHz -(该频段不包含此SCS) 2
网络设备可通过高层信令或DCI为终端设备配置测量CLI资源，还可以为一组终端设备配置时隙格式。例如，网络设备可以通过高层信令，例如TDD配置(configure)和/或时隙格式指示(slot format indicator，SFI)为一组终端设备配置时隙格式。TDD配置和时隙格式可配置时隙内的符号的格式，例如一个符号可以分为上行、下行、灵活三种类型。换句话说，一个符号可以为上行符号，也可以为下行符号，也可以为灵活符号。
但是，在可能的场景中，网络设备通过高层信令为终端设备配置的测量CLI资源中的部分资源或全部资源还被用于指示用于其他用途，可能会导致用于测量CLI的资源存在冲突。假设网络设备通过RRC为终端设备配置用于测量CLI资源为一个时隙内的一组符号。如果网络设备通过DCI又指示该组符号用于终端设备发送上行信号。即该组符号既用于测量CLI，又是用于发送上行信号，那么认为这组符号存在冲突。或者，网络设备通过SFI指示该时隙的这组符号为上行符号，也认为这组符号存在冲突。在可能的场景中，网络设备通过DCI指示的资源用途与SFI指示的时隙格式也可能存在冲突。例如，DCI指示终端设备一个时隙的一组符号上测量CLI，可认为该时隙的这组符号为下行符号，当SFI该时隙的这组符号为上行符号，也认为这组符号也存在冲突。在网络设备为终端设备配置的测量CLI的资源存在冲突的情况下，终端设备仍然在该测量CLI的资源上测量CLI，会影响终端设备接收信号或发送信号。
鉴于此，本申请一些实施例提供了一种CLI的测量方法，在该方法中，终端设备在满足特定条件下，才测量CLI或者取消测量CLI。也就是明确终端设备测量CLI或取消测量CLI的触发条件。由于终端设备在CLI资源冲突的情况下，取消测量CLI，所以可避免对终端设备发送信号或接收信号的影响。
下面结合附图对本申请实施例提供的技术方案进行详细介绍。
请参见图2，示出了本申请实施例提供的测量CLI方法的一种流程。在下文的介绍过程中，以该方法应用于图1所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。对于第二通信装置也是同样，第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制，例如第一通信装置可以是网络设备，第二通信装置是终端设备，或者第一通信装置和第二通信装置都是网络设备，或者第一通信装置和第二通信装置都是终端设备，或者第一通信装置是网络设备，第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置，等等。其中，网络设备例如为基站。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端设备为例。如果将本实施例应用在图1所示的网络架构，则下文中所述的网络设备可以是图1所示的网络架构中的网络设备，下文中的终端设备可以是图1中的任意终端设备。
在下文中，用于发送上行信号，可以是终端设备向网络设备发送的信号，也可以是终端设备向其他终端设备发送的信号。该上行信号可包括PUSCH、PUCCH、SRS，或者PRACH。终端设备接收的下行信号不为其他终端设备给终端设备发送的信号，例如，下行信号可以为网络设备给终端设备发送的信号，该下行信号可以是PDSCH，也可以是PDCCH，也可以是CSI-RS。
有效的资源指的是可以被通信设备使用发送信号或接收信号的资源。例如，对于终端设备而言，有效的PRACH时机指的是PRACH时机对应的资源能够被终端设备使用发送PRACH。
两个资源部分重叠或全部重叠可认为两个资源在时域和/或频域上存在交集，例如两个资源在时域上部分重叠或全部重叠可认为两个资源在时域上存在交集，两个资源在频域上部分重叠或全部重叠可认为两个资源在频域上存在交集。如果两个资源的用途不一样，可认为两个资源中重叠的资源存在冲突。换句话说，两个资源冲突可认为两个资源重叠或存在交集，且两个资源的用途不同。以时域资源为例，存在资源A和资源B，资源A所在符号用于下行传输，资源B所在符号用于上行传输，资源A所在的符号中的部分符号或者全部符号与资源B所在的符号中的部分符号或全部符号重叠，那么资源A和资源B重叠。
本申请实施例提及的符号由SFI指示为灵活类型(符号)/上行类型(符号)/下行类型(符号)，指的是网络设备为终端设备配置了SFI，且终端设备成功检测到SFI指示符号为灵活类型(符号)/上行类型(符号)/下行类型(符号)。
本申请实施例中，取消测量CLI，可以理解为终端设备不期望测量CLI，也可以认为，终端设备不期望接收用于测量CLI的信号。在另一些实施例中，取消测量CLI，可以理解为，终端设备不接收用于测量CLI的信号。下文以用于测量CLI的信号是SRS为例。
未检测到SFI指的是配置了SFI信令，但对于接收端而言，没有检测到SFI可能是发 送端没有发送SFI，也可能是发送端发送了SFI，但是接收端没有解码或译码成功SFI。
本申请实施例中，上行和下行是相对而言的，例如对于网络设备和终端设备而言，可将网络设备到终端设备称为下行，终端设备到网络设备称为上行(本文以此为例)。例如，对于第一终端设备和第二终端设备而言，可将第一终端设备到第二终端设备称为下行，第二终端设备到第一终端设备称为上行。
S201、网络设备向终端设备发送资源配置信息，相应的，终端设备接收该资源配置信息，该资源配置信息用于指示第一资源，第一资源可用于终端设备测量CLI。
为了减少或避免CLI，网络设备会为终端设备配置用于测量CLI的资源，用于终端设备测量CLI，以根据网络设备测量CLI的结果来协调调度终端设备使用的资源。例如，网络设备通过资源配置信息指示用于终端设备测量CLI的第一资源(在文本中也称为测量CLI资源)。终端设备接收资源配置信息后，在第一资源上测量CLI。由于终端设备接收的用于测量CLI的信号通常在第一资源的起始符号前到达，因此，终端设备通常会在第一资源的起始符号之前的N0个符号上开始测量CLI。为方便描述，下文中将“用于测量CLI的时域资源”称为至少一个符号。至少一个符号可包括第一资源所在的符号，也可以包括第一资源所在的符号以及第一资源所在的符号之前的N0个符号。
S202、终端设备确定满足第一特定条件，取消测量CLI。
由于网络设备可通过信令配置符号的类型。例如网络设备可通过DCI灵活地指示某些资源用于发送上行信号或接收下行符号。又例如网络设备可通过SFI指示符号的类型。因此，当网络设备为终端设备配置第一资源用于测量CLI时，网络设备也可能通过信令指更改第一资源所在的一个符号或多个符号的传输方向或类型。例如，网络设备配置了第一资源用于测量CLI，网络设备又通过DCI指示第一资源所在的一个或多个符号用于发送上行信号，或者接收下行信号。这种情况下，第一资源冲突，如果终端设备在第一资源上测量CLI，显然会影响终端设备发送上行信号或接收下行信号。第一资源发生冲突是终端设备不期望出现的。也可以认为，终端设备不期望在用于测量CLI的时域资源上发送上行信号或接收下行信号。为此，终端设备在确定第一资源或用于测量CLI的时域资源发生冲突的情况下，取消测量CLI。
首先，介绍用于测量CLI的时域资源发生冲突的几种情况。应理解，用于测量CLI的时域资源发生冲突指的是至少一个符号中的一个或多个符号还用于发送上行信号或接收下行信号。
请参见图3，示出了用于测量CLI的时域资源发生冲突的几种情况。
如图3所示，资源1为有效的PRACH时机所在的符号以及有效的PRACH时机之前的Ngap个符号。资源2为第一资源所在的符号和第一资源所在的符号之前的N0个符号。资源3为网络设备配置的用于发送上行信号的资源所在的符号。资源4是由RRC信令配置为上行符号或由SFI指示为上行符号。资源5是网络配置的用于接收下行信号的资源。资源1中的符号不能为下行符号，当资源1与资源2部分或全部重叠时，且在资源2测量CLI时，可认为重叠的符号为下行符号，显然存在冲突。当资源2中与资源3部分或全部重叠时，可认为重叠的符号既用于测量CLI，又用于发送上行信号，显然存在冲突。当资源2与资源4部分或全部重叠时，可认为重叠的符号既用于测量CLI，又为上行符号，显然存在冲突。当资源2与资源5所在的符号部分或全部重叠时，且第一资源所在的子载波与资源5所在的子载波部分或全部重叠时，可认为重叠的时频资源及用于测量CLI，又用 于接收其他下行信号，显然存在冲突。
例如，终端设备不支持cli-SRS-RSRP-FDM_DL时，也就是终端设备不支持以FDM方式接收用于测量CLI的信号和其他信号时，终端设备不期望在进行SRS-RSRP测量的符号及其前N0个符号接收PDCCH，或PDSCH或CSI-RS信号。又例如，终端设备不支持cli-RSSI-FDM-DL时，终端设备不期望在进行CLI-RSSI测量的符号及其前N0个符号接收PDCCH，或PDSCH或CSI-RS信号。
又例如，终端设备支持cli-SRS-RSRP-FDM_DL时，也就是终端设备支持测量CLI资源和其他信号频分多路复用，终端设备不期望在进行SRS-RSRP测量的符号及其前N0个符号接收PDCCH，或PDSCH或CSI-RS信号时，进行SRS-RSRP测量的频域资源与用于接收下行信号的频域资源部分或者全部重叠。又例如，终端设备支持cli-RSSI-FDM-DL时，终端设备不期望在进行CLI-RSSI测量的符号及其前N0个符号接收PDCCH，或PDSCH或CSI-RS信号时，进行CLI-RSSI测量频域资源与用于接收下行信号的频域资源部分或者全部重叠。
因此，如果出现终端设备不期望的情况，终端设备可取消测量CLI，优先发送上行信号或接收下行信号。为方面描述，本文将满足终端设备取消测量CLI的条件称为第一特定条件。
第一特定条件可以包括如下条件中的一种或多种，下面分别介绍这几种特定条件。需要说明的是，下文中的，至少一个符号可包括第一资源所在的符号，也可以包括第一资源所在的符号以及第一资源所在的符号之前的N0个符号。
条件一，至少一个符号与第二资源所在的符号部分或全部重叠，该第二资源所在的符号为上行符号。
用于测量CLI的至少一个符号应该为下行符号或者灵活符号或者用于下行传输。如果至少一个符号与上行符号部分或全部重叠，可认为至少一个符号中的部分符号或全部符号还被用于上行传输，显然至少一个符号存在冲突。这种情况下，终端设备在至少一个符号上可取消测量CLI，即至少一个符号优先被用于上行传输，可避免由于测量CLI对发送上行信号的影响。
例如，第二资源所在的符号由RRC信令配置为上行符号。终端设备根据网络设备发送的RRC信令确定第二资源所在的符号为上行符号，当至少一个符号与第二资源所在的符号部分或全部重叠，那么终端设备在至少一个符号上取消测量CLI。
又例如，第一资源由RRC配置用于测量CLI，第二资源所在的符号由SFI指示为上行符号。终端设备根据网络设备发送的SFI确定第二资源所在的符号为上行符号，终端设备根据RRC和SFI确定至少一个符号与第二资源所在的符号部分或全部重叠，那么终端设备在至少一个符号上取消测量CLI。
又例如，当第一资源由DCI指示用于测量CLI，第二资源所在的符号由SFI指示为上行符号，至少一个符号与第二资源所在的符号部分或全部重叠时，终端设备不期望DCI指示第一资源用于测量CLI，SFI指示第二资源所在的符号为上行符号。所以，当至少一个符号与第二资源所在的符号部分或全部重叠，终端设备取消测量CLI。
条件二，至少一个符号与第三资源部分或全部重叠，第三资源包括一个或多个有效的PRACH时机所在的符号。或者，至少一个符号与第三资源部分或全部重叠，第三资源包括一个或多个有效的PRACH时机所在的符号，以及该一个或多个有效的PRACH时机之 前的N gap个符号中的至少一个符号，所述N gap为大于或等于0的整数。应理解，PRACH时机所在符号不能为下行符号，一个或多个有效的PRACH时机之前的N gap个符号中的至少一个符号也不能为下行符号。终端设备在至少一个符号测量CLI时，终端设备可认为至少一个符号为下行符号。至少一个符号与第三资源部分或全部重叠时，显然存在冲突。终端设备在至少一个符号上取消测量CLI，以避免影响有效PRACH时机上信号的发送。
可选的，N gap与随机接入前导码(preamble)的SCS相关。例如，preamble的SCS为1.25kHz或5kHz，那么N gap为0。例如，preamble的SCS为15kHz或30kHz或60kHz或120kHz，那么N gap为2。应理解，preamble的SCS的取值和N gap的取值之间的关系仅是举例示意。
条件三，至少一个符号中的一个或多个符号由DCI指示用于发送上行信号或接收下行信号。网络设备可通过DCI灵活地指示某些资源用于发送上行信号或接收下行符号。即使网络设备为终端设备配置用于测量CLI的资源，难免出现该资源被复用。例如网络设备通过DCI指示复用至少一个符号中的一个或多个符号发送上行信号或接收下行信号。这种情况下，至少一个符号中的一个或多个符号存在冲突，终端设备在至少一个符号上也取消测量CLI，即至少一个符号优先被用于发送上行信号或接收下行信号。
例如，所述第一资源由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由DCI指示用于发送上行信号，终端设备取消测量CLI。
又例如，所述至少一个符号由DCI指示用于测量CLI，所述至少一个符号中的一个或多个符号由DCI指示用于发送上行信号。终端设备不希望这种情况出现，当这种情况出现，终端设备取消测量CLI。
又例如，所述至少一个符号与第四资源所在符号部分或全部重叠，且第四资源所在的子载波和至少一个子载波部分或全部重叠，其中，所述至少一个子载波包括所述第一资源所在的子载波。例如，所述第一资源由RRC配置用于测量CLI，且所述第四资源由DCI指示用于接收下行信号，终端设备取消测量CLI。又例如，所述至少一个符号由DCI指示用于测量CLI，且所述第四资源由DCI指示用于接收下行信号。终端设备不希望这种情况出现，当这种情况出现，终端设备取消测量CLI。
一种可能的实现方式中，第一资源由RRC配置用于测量CLI，终端设备也不希望至少一个符号中的一个或多个符号由RRC配置发送上行信号或接收下行信号。所以所述至少一个符号由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由RRC配置发送上行信号或接收下行信号，终端设备取消测量CLI。
条件四，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号或RRC没有配置所述至少一个符号的类型，且所述至少一个符号有SFI配置，终端设备未检测到SFI，终端设备未检测到DCI指示在所述第一资源测量CLI。或者，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号或RRC没有配置所述至少一个符号的类型，终端设备检测到SFI指示所述至少一个符号中的一个或多个符号为灵活符号，终端设备未检测到DCI指示在所述第一资源测量CLI。
网络设备为终端设备配置了用于测量CLI的第一资源，但网络设备可能没有配置第一资源中的符号为上行符号还是下行符号。例如，网络设备未配置第一资源中的符号的类型，或者，网络设备配置第一资源中的符号为灵活符号。这种情况下，在所述至少一个符号有SFI配置，且终端设备未检测到SFI时，终端设备可认为所述至少一个符号中的一个或多 个符号的方向未配置。或者，在终端设备检测到SFI指示所述至少一个符号中的一个或多个符号为灵活符号时，终端设备认为所述至少一个符号中的一个或多个符号为保留符号，终端设备不使用该保留符号。一种可选的方式中，对于保留符号，由于终端设备无法确定保留符号的用途，网络设备可以通过DCI触发终端设备是否在第一资源上测量CLI，如果没有DCI指示终端设备在第一资源上测量CLI，终端设备不在至少一个符号上测量CLI。如果终端接收到DCI指示终端设备在第一资源上测量CLI，终端设备在至少一个符号上测量CLI。
条件五，终端设备配置有多个服务小区，且多个服务小区包括参考小区和其他小区，所述其他小区为所述服务小区中除参考小区之外的服务小区。至少一个符号在参考小区的传输方向与至少一个符号在其他小区的传输方向不同。
作为一种示例，条件五包括：第一资源在参考小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在其他小区由DCI指示用于发送上行信号或接收下行符号。假设第一资源在参考小区用于测量CLI，那么终端设备不期望第一资源在其他小区被用于发送上行信号或接收下行信号，例如PDSCH，PDCCH或CSI-RS。由于DCI指示第一资源所在的符号中的部分符号或全部符号在其他小区用于发送上行信号或接收下行信号，即第一资源所在的符号中的一个或多个符号既用于测量CLI又用于发送上行信号或接收下行信号，为了避免第一资源发生冲突，终端设备取消测量CLI。
作为另一种示例，条件五包括：第一资源在其他小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在参考小区由RRC配置为上行符号。如果第一资源在其他小区用于测量CLI，但是在参考小区被配置为上行符号，那么第一资源也可能会发生冲突。为了避免第一资源发生冲突，终端设备取消测量CLI。
作为另一种示例，条件五包括：第一资源在其他小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在参考小区由RRC配置为用于发送上行信号或接收下行符号。同理，如果第一资源在其他小区用于测量CLI，但是在参考小区被配置用于发送上行信号或接收下行符号，那么第一资源也可能会发生冲突。这种情况下，终端设备不要求在所述至少一个符号上测量CLI，为了避免第一资源发生冲突，终端设备取消测量CLI。
需要说明的是，上述三种条件五可分别认为是一种第一特定条件，终端设备确定只要满足上述三种条件五的任意一种，终端设备不在第一资源上测量CLI，或者终端设备不在第一资源以及第一资源所在的符号之前的N0个符号上测量CLI。
在一些实施例中，参考小区和其他小区对应的频段可以相同，也可以不相同。本申请实施例对此不作限制。如果参考小区和其他小区对应的频段相同，允许一个符号以FDM的方式接收用于测量CLI的信号，以及接收下行信号，用于测量CLI的频域资源可能存在冲突。例如，第一资源所在的子载波和第四资源所在的子载波部分或全部重叠，第四资源所在的符号与至少一个符号部分或全部重叠，可认为第一资源和第四资源存在冲突。这种情况下，终端设备也取消测量CLI。也就是，第一特定条件也可以包括：如果参考小区和其他小区对应的频段相同，第一资源所在的子载波和第四资源所在的子载波部分或全部重叠，第四资源所在的符号与至少一个符号部分或全部重叠。
条件六，第一资源在服务小区由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号在参考小区和其他小区的传输方向不同。例如，所述至少一个符号中的一个或多个符号在参考小区由RRC配置为下行符号，所述至少一个符号中的一个或多个符号在 其他小区由RRC配置为上行符号。又例如，所述至少一个符号中的一个或多个符号在参考小区由RRC配置为上行符号，所述至少一个符号中的一个或多个符号在其他小区由RRC配置为下行符号。这种情况下，终端设备认为所述至少一个符号中的一个或多个符号是灵活的，RRC配置终端设备在第一资源所在的符号上测量CLI时，终端设备不要求在所述至少一个符号上测量CLI。应理解，第一资源在服务小区被配置用于测量CLI，无论第一资源所在的符号在参考小区和其他小区被配置为上行符号，还是下行符号，只要第一资源所在的符号在参考小区和其他小区的传输方向不同，终端设备认为第一资源所在的符号是灵活的，终端设备不要求测量CLI。这种情况下，终端设备也不在第一资源上测量CLI，或者不在第一资源以及第一资源所在的符号之前的N0个符号测量CLI。
在条件六下，参考小区和其他小区对应的频段可以不同。
一种可能的实现方式中，终端设备在确定是否测量CLI之前，除了确定是否满足第一特定条件之前，还可以确定终端设备是否满足一定的特性。例如，终端设备满足如下四种特性中的一种或多种的情况下，终端设备可取消测量CLI。
示例性的，终端设备需满足：终端设备支持半双工模式，且终端设备配置有多个服务小区；终端设备不支持在任意服务小区中同时发送和接收；终端设备具有非成对频谱CA的半双工能力；终端设备在任意一个服务小区中没有SFI配置。例如终端设备支持半双工模式，即终端设备不能同时发送和接收。这些情况下，当用于测量CLI的第一资源被用于例如发送上行信号或接收下行信号，会发生资源冲突，终端设备需确定是否测量CLI，以尽量避免影响发送上行信号或接收下行信号。
需要说明的是，条件一到条件六中的任意一种条件属于第一特定条件，条件一到条件六中的多种条件的任意结合也属于第一特定条件。且条件一到条件六的任意条件，结合终端设备需要满足的特性，也可以看作是第一特定条件。
本申请实施例明确终端设备取消测量CLI的触发条件，例如前述的任意第一特定条件。例如，第一资源与其他资源存在冲突的情况下，终端设备取消测量CLI。又例如，在SFI指示与第一资源存在冲突，终端设备也取消测量CLI。由于终端设备在第一资源冲突的情况下，取消测量CLI，所以可避免对终端设备在第一资源上发送信号或接收信号的影响。
考虑到网络设备可以通过DCI指示用于测量CLI的资源，但是用于测量CLI的资源也可能会由SFI指示具体的类型，这种情况下，用于测量CLI的资源可能发生冲突。下面提供另一种测量CLI的方法，该方法进一步明确终端设备测量CLI的特定条件，以避免第一资源所在的符号发生冲突，进而尽量避免终端设备的通信异常。
请参见图4，示出了本申请实施例提供的测量CLI方法的另一种流程。下文该方法应用于图1所示的网络架构为例。图4所示流程图2的不同之处在于，侧重于明确终端设备测量CLI的特定条件，与图2的重复之处具体可参考前述图2实施例的描述，这里不再赘述。
S401、网络设备向终端设备发送资源配置信息，相应的，终端设备接收该资源配置信息，该资源配置信息用于指示第一资源，第一资源可用于终端设备测量CLI。
S401的具体实现同S201，具体可参考前述S201的相关内容的介绍，这里不再赘述。
S402、终端设备确定满足第二特定条件，在第一资源所在的符号以及第一资源所在的符号之前的N0个符号上测量CLI。
符号的方向可以被RRC配置上行或者下行或者灵活。由RRC配置的灵活符号还可以 进一步被指示为上行或下行。例如，RRC配置为灵活的符号还可以被半静态测量配置来明确指示用于发送上行信号或用于接收下行信号。其中，半静态测量配置可包括例如RRC配置的测量CLI或者CSI-RS测量或者SRS测量。举例来说，某个符号由RRC配置为灵活符号，另外，RRC配置该符号测量CLI，那么终端设备可认为该符号为下行符号，即该符号的传输方向为下行。由RRC配置为灵活的符号还可以被SFI指示为上行符号或下行符号。或者由RRC配置为灵活的符号还可以被DCI指示用于发送信号或接收信号。举例来说，某个灵活符号被DCI指示用于测量CLI，或者用于接收下行信号，或者用于发送上行信号。如果由RRC配置为灵活的符号被DCI指示用于发送信号，那么终端设备可认为该符号为上行符号。同理，如果由RRC配置为灵活的符号被DCI指示用于接收信号，那么终端设备可认为该符号为下行符号。这样就有可能导致一个符号冲突。示例性的，网络设备通过DCI指示的资源用途与SFI指示的时隙格式也可能存在冲突。例如，DCI指示终端设备一个时隙的一组符号上测量CLI，但是SFI该时隙的这组符号为上行符号，显然这组符号也存在冲突。一旦符号发生冲突，那么需要确认不同配置下相互覆盖的基本准则。例如，基本准则可包括：RRC配置的上行符号及下行符号不能被修改；或者，RRC配置的灵活符号可被半静态测量配置，SFI指示，DCI指示发送或接收信号更改；半静态测量配置中的上行及下行配置可被SFI指示，DCI指示发送或接收信号更改。一旦符号方向发生更改，半静态测量相关的行为将被取消；DCI指示发送或接收信号的方向不能和SFI指示的上行和下行冲突，但是可以对SFI配置中的灵活部分进行修改。
终端设备可在这些基本准则下确定测量CLI相关的行为。即进一步明确终端设备测量CLI的特定条件，以避免第一资源发生冲突，尽量避免终端设备的通信异常。例如，本申请实施例约定了在DCI指示以及SFI指示下，终端设备测量CLI的行为。即终端设备在满足某个或某些特定条件的情况下，终端设备才测量CLI。为方便描述，本文将终端设备测量CLI的条件称为第二特定条件。第二特定条件可以包括如下条件中的一种或多种，下面分别介绍这几种特定条件。
条件一，第一资源由RRC配置用于测量CLI，所述至少一个符号由RRC配置为下行符号。如果RRC配置第一资源用于测量CLI，那么该第一资源所在的符号应当为下行符号。当RRC配置所述至少一个符号为下行符号，即使终端设备可在所述至少一个符号上测量CLI，也不会引起至少一个符号的冲突。
条件二，第一资源由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除被配置为灵活符号之外的符号为下行符号，且终端设备未配置SFI，且终端未检测到DCI指示在所述至少一个符号中的一个或多个符号由发送上行信号或接收下行信号。如果所述至少一个符号中的一个或多个符号为灵活符号，所述至少一个符号除灵活符号之外的符号为下行符号。如果终端设备未配置SFI，那么所述至少一个符号的方向不会被SFI改变。进一步的，终端设备未检测到DCI指示在所述至少一个符号中的一个或多个符号发送上行信号或接收下行信号，那么所述至少一个符号不是上行符号。因此，终端设备可认为所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件三，第一资源由RRC配置用于测量CLI，RRC没有配置所述至少一个符号的类型，且所述终端设备未配置SFI，且所述终端未检测到DCI指示在所述至少一个符号中的一个或多个符号由发送上行信号或接收下行信号。由于至少一个符号没有明确规定是何种 类型的符号，那么至少一个符号可作为下行符号，也可以作为上行符号。如果终端设备未配置SFI，那么所述至少一个符号的方向不会被SFI改变。进一步的，终端设备未检测到DCI指示在所述至少一个符号中的一个或多个符号由发送上行信号或接收下行信号，那么所述至少一个符号不是上行符号，所述至少一个符号中的一个或多个符号没有与下行信号重叠。因此，终端设备可认为所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件四，第一资源由RRC配置用于测量CLI，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号为由RRC配置为下行符号，且终端设备检测到SFI指示所述至少一个符号中的灵活符号为下行符号。或者，第一资源由RRC配置用于测量CLI，RRC没有配置所述至少一个符号的类型，且终端设备检测到SFI指示所述至少一个符号为下行符号。
与条件二或条件三类似，如果第一资源所在的符号没有明确规定是何种类型的符号，那么第一资源所在的符号可作为下行符号，也可以作为上行符号。所述至少一个符号包括灵活符号和下行符号，进一步的，SFI指示所述至少一个符号为下行符号，那么终端设备明确所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件五，所述至少一个符号由RRC配置为下行符号，所述终端设备检测到DCI指示在所述第一资源测量CLI。如果所述至少一个符号由RRC配置为下行符号，那么终端设备明确所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起至少一个符号的冲突。
条件六，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号为由RRC配置为下行符号，且终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号没有SFI配置。或者，RRC没有配置所述至少一个符号的类型，且终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号没有SFI配置。所述至少一个符号中的一个或多个符号为灵活符号，或者所述至少一个符号的类型未配置。灵活符号或者类型未配置的符号可用于接收下行信号，也可以用于发送上行信号。如果所述终端设备未配置SFI，那么所述至少一个符号的方向不会被SFI改变。进一步的，DCI指示终端设备测量CLI，终端设备可以认为所述至少一个符号为下行符号。这种情况下，终端设备可在所述至少一个符号上测量CLI，不会引起所述至少一个符号的冲突。
条件七，所述至少一个符号中的一个或多个符号由RRC配置为灵活符号，所述至少一个符号中除灵活符号之外的符号为由RRC配置为下行符号，终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号有SFI配置，终端设备未检测到SFI或者终端设备检测到SFI指示所述至少一个符号为灵活符号或下行符号。或者，RRC没有配置所述至少一个符号的类型，终端设备检测到DCI指示在第一资源测量CLI，且所述至少一个符号有SFI配置，终端设备未检测到SFI或者终端设备检测到SFI指示所述至少一个符号为灵活符号或下行符号。相较于条件六来说，如果所述至少一个符号有SFI配置，但是终端设备未检测到SFI，DCI指示终端设备测量CLI，终端设备可以认为所述至少一个符号为下行符号。或者，终端设备检测到SFI指示所述至少一个符号为灵活符号或下行符号，根据SFI指示及DCI指示测量CLI，终端设备可以认为所述至少一个符号为下行符号。终端 设备可在所述至少一个符号上测量CLI，不会引起所述至少一个符号的冲突。
本申请实施例明确终端设备测量CLI或不测量CLI的触发条件。例如，配置的CLI资源与其他资源存在冲突的情况下，终端设备取消测量CLI。又例如，在SFI指示与配置的CLI资源存在冲突，终端设备也可取消测量CLI。由于终端设备在CLI资源冲突的情况下，取消测量CLI，所以可避免对终端设备发送数据或接收数据的影响。
上述图2和图4的流程可结合，即本申请实施例提供的测量CLI方法包括S201、S202以及S402，其中，S202和S402的执行顺序不作限制。也就是，S202可在S402之前执行，也可以在S402之后执行。
上述本申请提供的实施例中，分别从终端设备和网络设备之间交互的角度对本申请实施例提供的方法进行了介绍。其中，网络设备执行的步骤也可以由不同的通信装置来分别实现。例如：第一装置用于确定第一资源，第二装置用于发送用于指示第一资源的资源配置信息，也就是说第一装置和第二装置共同完成本申请实施例中网络设备执行的步骤，本申请不限定具体的划分方式。当网络架构中包括一个或多个分布单元(distributed unit，DU)、一个或多个集中单元(centralized unit，CU)和一个或多个射频单元(RU)时，上述网络设备执行的步骤可以分别由DU、CU和RU来实现。为了实现上述本申请实施例提供的方法中的各功能，终端设备和网络设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
