为了更好的理解本公开实施例公开的一种上行波束的测量方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备、一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、一个终端设备12。

可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的上行波束的测量方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
需要说明的是，相关技术中，网络设备通常会通过无线资源控制(Radio Resource Control，RRC)信令为终端设备配置服务小区(serving cell)对应的SRS资源，从而终端设备即可在配置的时频域资源上发送SRS，其中不同的SRS对应不同的发射波束，服务小区在接收到SRS后，即可根据接收功率，找到最佳的发射波束。即相关技术中，只能确定服务小区与终端设备之间的上行波束，不能确定终端设备与邻小区之间的合适的上行波束。本公开中，网络设备不仅可以为终端设备配置服务小区对应的SRS资源，还可以为终端设备配置邻小区(non-serving cell)对应的SRS资源。从而，终端设备可以基于邻小区对应的SRS资源，向邻小区发送SRS，以使邻小区根据测量各SRS的接收功率，确定邻小区与终端设备间的最佳的发射波束，进而为终端设备提供服务。
可选的，配置信息中还可以包括：邻小区对应的路径损耗参考信号(path loss reference signal，PL RS)，以及邻小区对应的空间关系信息参数(spatialRelationInfo)等，本公开对此不做限定。从而终端设备在收到该配置信息后，即可根据邻小区对应的PL RS，确定SRS的发射功率，根据spatialRelationInfo，确定SRS对应的发射波束等，进而再基于确定的发射功率及发射波束，向邻小区发送SRS。
可选的，邻小区的数量可以为1个或多个。比如，1个、3个、5个等等，本公开对此不做限定。
可选的，邻小区对应的SRS可以为周期性(cyclicity)SRS、半静态(Semi-persistent)SRS、或非周期(Aperiodic)SRS，本公开对此不做限定。
通过实施本公开实施例，终端设备接收包括邻小区对应的探测参考信号SRS的配置信息，之后即可向邻小区发送SRS，以使邻小区根据测量的接收功率，确定终端设备最佳的发射波束。由此，实现了支持终端设备与邻小区之间的上行波束测量，为实现邻小区为终端设备提供服务提供了依据。
请参见图3，图3是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤31的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤32，接收第一小区发送的第一多媒体接入控制MAC控制单元CE，第一MAC CE用于激活或去激活第一小区对应的半静态SRS，第一小区为服务小区或邻小区。
可以理解的是，对于半静态的SRS，需要根据MAC CE对半静态SRS激活之后，终端设备才可以基于激活后的半静态SRS对应的时频域资源，向服务小区或邻小区发送SRS。
举例来说，如果为终端设备提供服务的小区发生变化，由小区A变化为小区B，则终端设备需要将小区A对应的半静态SRS去激活，小区B对应的半静态SRS激活。本实施例中，终端设备可以根据小区A发送的MAC CE去激活小区A对应的半静态SRS，根据小区B发送的MAC CE激活小区B对应的半静态SRS。
通过实施本公开实施例，终端设备首先接收邻小区对应的SRS，之后根据接收的第一小区发送的MAC CE，激活或去激活服务小区或邻小区对应的半静态SRS。由此，终端设备在对半静态SRS进行激活之后，即可获取终端设备与邻小区之间的合适的上行波束对，进而可以由邻小区为终端设备提供服务。
请参见图4，图4是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤41，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤41的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤42，接收指示信息，其中，指示信息用于为终端设备指示波束。
可选的，网络设备可以通过MAC CE向终端设备发送指示信息。或者，网络设备也可以通过DCI向终端设备发送指示信息。
步骤43，在指示的波束对应的第二小区与当前为终端设备提供数据服务的第三小区不同的情况下，去激活第三小区中处于激活态的半静态SRS。
需要说明的是，波束与小区之间的对应关系可以是预先配置好的。
可以理解的是，指示的波束对应的第二小区可以为即将为终端设备提供服务的小区，因此，在网络设备为终端设备指示波束之后，若指示的波束对应的第二小区与当前为终端设备提供数据服务的第三小区不同，则终端设备可以将第三小区中处于激活态的半静态SRS去激活。从而终端设备即可根据指示的波束向第二小区发送SRS。
通过实施本公开实施例，终端设备在小区间波束管理的场景中，首先接收邻小区对应的SRS，之后接收为终端设备指示波束的指示信息，最后在指示的波束对应的第二小区与当前为终端设备提供数据服务的第三小区不同的情况下，去激活第三小区中处于激活态的半静态SRS。由此，终端设备即可基于指示的波束向对应的第二小区发送SRS，并由第二小区为终端设备提供服务。
请参见图5，图5是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图5所示，该方法可以包括但不限于如下步骤：
步骤51，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤51的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤52，在邻小区变化的情况下，将邻小区对应的处于激活态的半静态SRS去激活，其中，邻小区与服务小区对应的定时提前与终端设备对应的定时提前(Timing Advance，TA)不同。
可以理解的是，邻小区与服务小区对应的TA与终端设备对应的TA不同时，邻小区与服务小区分别对自己对应的SRS进行管理。此时，随着终端设备的移动，终端设备对应的邻小区可能由邻小区A变化为邻小区B。此时，终端设备就不需要向邻小区A发送SRS，因此，终端设备需要将邻小区A对应的处于激活态的半静态SRS去激活。
可选的，终端设备可以根据网络设备发送的高层信令，确定邻小区发生变化。
通过实施本公开实施例，终端设备在inter-cell multi-TRP场景中，首先接收邻小区对应的SRS，之后在邻小区变化，且邻小区与服务小区对应的定时提前与终端设备对应的定时提前不同的情况下，将邻小区对应的处于激活态的半静态SRS去激活。由此，不仅实现了支持终端设备与邻小区之间的上行波束测量，而且实现了在邻小区变化时，对半静态SRS的可靠去激活，从而即保证了邻小区可以为终端设备提供可靠服务，又避免了资源浪费。
请参见图6，图6是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图6所示，该方法可以包括但不限于如下步骤：
步骤61，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤61的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤62，在邻小区变化的情况下，将对应小区列表中仅包含邻小区标识的半静态SRS去激活。其中，邻小区与服务小区对应的定时提前与终端设备对应的定时提前相同，小区列表中包括的小区为基于SRS进行测量的小区。
需要说明的是，在邻小区与服务小区对应的TA与终端设备对应的TA相同的情况下，邻小区和服务小区可能会基于同一个SRS进行同时测量，若直接将半静态SRS去激活，则可能会导致服务小区对应的SRS不能用。因此，终端设备可以记录基于每个SRS进行测量的小区列表，之后在邻小区变化的情况下，基于半静态SRS对应的小区列表中包含的小区情况，确定是否对半静态SRS进行去激活。
举例来说，终端设备在移动过程中，由邻小区A变化至了邻小区B，且半静态SRS#1对应的小区列表中，仅包含邻小区A的标识，半静态SRS#2对应的小区列表中，包含邻小区A及邻小区B，则此时，仅可以把半静态SRS#1进行去激活。
可选的，终端设备可以根据接收的第一MAC CE，确定每个半静态SRS对应的小区列表。
可选的，在邻小区变化，且邻小区与服务小区对应的定时提前与终端设备对应的定时提前相同的情况下，也可以将邻小区对应的处于激活态的半静态SRS去激活。
通过实施本公开实施例，终端设备在inter-cell multi-TRP场景中，首先接收邻小区对应的SRS，之后在邻小区变化，且邻小区与服务小区对应的定时提前与终端设备对应的定时提前相同的情况下，将对应小区列表中仅包含邻小区标识的半静态SRS去激活。由此，不仅实现了支持终端设备与邻小区之间的上行波束测量，而且实现了在邻小区变化时，对半静态SRS的可靠去激活，从而即保证了邻小区可以为终端设备提供可靠服务，又避免了 资源浪费。
请参见图7，图7是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图7所示，该方法可以包括但不限于如下步骤：
步骤71，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤71的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤72，接收服务小区发送的第一下行控制信息DCI，其中，第一DCI用于触发邻小区或服务小区对应的非周期SRS。
可选的，网络设备可以将服务小区的DCI中的SRS请求request域中增加N比特bits，以指示终端设备触发邻小区和/或服务小区对应的非周期SRS。其中，N可以为2、4等等，本公开对此不做限定。
可以理解的是，邻小区及服务小区对应的非周期SRS被触发之后，终端设备即可根据被触发的SRS的配置信息发送SRS，以使服务小区和/或邻小区进行上行波束测量。
通过实施本公开实施例，网络设备首先向终端设备配置邻小区对应的SRS资源，之后即可通过服务小区向终端设备发送第一DCI，以触发邻小区及服务小区对应的非周期SRS，从而使得终端设备即可利用被触发的SRS资源发送SRS，以完成上行波束的测量。由此，通过服务小区发送的DCI即可触发服务小区及邻小区对应的非周期SRS，从而实现了终端设备与邻小区之间的上行波束测量，为实现邻小区为终端设备提供服务提供了依据。
请参见图8，图8是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图8所示，该方法可以包括但不限于如下步骤：
步骤81，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤81的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤82，接收服务小区发送的第二MAC CE，其中，第二MAC CE用于指示邻小区及服务小区对应的多个非周期的SRS中被选中的SRS。
可选的，网络设备可以通过MAC CE中的多个bits来指示邻小区及服务小区对应的多个非周期的SRS中被选中的SRS。比如，邻小区及服务小区共对应N个非周期SRS，则MAC CE中可以至少包括与各个SRS对应的选择状态标识位T0～TN，Ti＝1表示其对应的第i个SRS资源集被选中，Ti＝0则表示其对应的第i个SRS资源集未被选中。举例来说，T0＝1,表示第一个SRS资源集被选中。
举例来说，终端设备接收的配置信息中可以包含8个邻小区及服务小区对应的SRS，则第二MAC CE中，可以包含8个选择状态标识位，之后，服务小区可以通过向终端设备发送第二MAC CE，指示终端设备从8个SRS中选择2个、4个、5个SRS等等。
步骤83，接收服务小区发送的第二DCI，其中，第二DCI用于触发被选中的SRS。
可以理解的是，对应非周期的SRS，需要接收网络设备发送的DCI，对非周期SRS进行触发之后，才可以基于触发的SRS向邻小区及服务小区发送SRS。
本公开中，可以通过服务小区向终端设备先发送第二MAC CE，以从多个非周期SRS中选择部分SRS，进而再由服务小区向终端设备发送第二DCI，以触发被选中的SRS中的部分SRS，之后，终端设备即可基于被触发的SRS资源向邻小区或者服务小区发送SRS，以完成上行波束的测量。
举例来说，终端设备接收的配置信息中可以包含8个邻小区及服务小区对应的SRS， 之后，终端设备再接收网络设备发送第二MAC CE，根据第二MAC CE的指示从8个SRS中选择4个SRS，最后接收网络设备发送的第二DCI，以触发被选中的SRS。
通过实施本公开实施例，终端设备首先接收邻小区对应的SRS，之后，即可根据接收的服务小区发送的第二MAC CE，从多个非周期SRS中选择部分SRS，并根据接收的服务小区发送的第二DCI，确定待触发的SRS，之后，即可基于被触发的SRS完成上行波束测量。由此，通过服务小区发送的第二MAC CE及第二DCI，即可实现对邻小区及服务小区对应的多个非周期性SRS中的部分SRS的触发，从而实现了支持终端设备与邻小区之间的上行波束测量，为实现邻小区为终端设备提供服务提供了依据。
请参见图9，图9是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由终端设备执行。如图9所示，该方法可以包括但不限于如下步骤：
步骤91，接收配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤91的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤92，接收第三小区发送的第三DCI，其中，第三DCI用于触发第三小区对应的非周期的SRS，第三小区为服务小区或邻小区。
可以理解的是，对应非周期的SRS，终端设备需要根据接收的DCI，对非周期SRS进行触发之后，才可以基于触发的SRS向邻小区及服务小区发送。
本公开中，邻小区及服务小区，可以通过各自的DCI向终端设备指示触发的非周期的SRS，之后，终端设备即可根据服务小区指示触发的SRS，完成服务小区的上行波束测量，并基于邻小区指示触发的SRS，完成邻小区的上行波束测量。
举例来说，服务小区通过向终端设备发送第三DCI，指示触发其对应的非周期性SRS资源集set#1被触发，而邻小区通过向终端设备发送第三DCI，指示触发其对应的非周期性SRS资源集set#5，则终端设备即可基于SRS set#1对应的资源，向服务小区发送SRS，以完成服务小区对应的上行波束测量，并基于SRS set#5对应的资源，向邻小区发送SRS，以完成邻小区对应的上行波束测量。
通过实施本公开实施例，终端设备首先接收用于配置邻小区对应的SRS的配置信息，之后即可根据接收到的第三小区发送的第三DCI，触发第三小区对应的非周期的SRS。由此，服务小区及邻小区，可以各自触发其对应的非周期SRS，从而实现了终端设备与邻小区之间的上行波束测量，为实现邻小区为终端设备提供服务提供了依据。
请参见图10，图10是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由网络设备执行。如图10所示，该方法可以包括但不限于如下步骤：

可选的，配置信息中还可以包括：邻小区对应的路径损耗参考信号(path loss  reference signal，PL RS)，以及邻小区对应的空间关系信息参数(spatialRelationInfo)等，本公开对此不做限定。从而终端设备在收到该配置信息后，即可根据邻小区对应的PL RS，确定SRS的发射功率，根据spatialRelationInfo，确定SRS对应的发射波束等，进而再基于确定的发射功率及发射波束，向邻小区发送SRS。
可选的，邻小区的数量可以为1个或多个。比如，1个、3个、5个等等，本公开对此不做限定。
可选的，邻小区对应的SRS可以为周期性(cyclicity)SRS、半静态(Semi-persistent)SRS、或非周期(Aperiodic)SRS，本公开对此不做限定。

其中，步骤111的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤112，基于邻小区或者服务小区对应的时频域资源，发送第一多媒体接入控制MAC控制单元CE，第一MAC CE用于激活或去激活邻小区与服务小区中任一小区对应的半静态SRS。
可以理解的是，对于半静态的SRS，需要根据网络设备发送的MAC CE对半静态SRS激活之后，终端设备才可以基于激活后的半静态SRS对应的时频域资源，向服务小区或邻小区发送SRS。
举例来说，如果为终端设备提供服务的小区发生变化，由小区A变化为小区B，则网络设备可以基于小区A对应的时频域资源，向终端设备发送MAC CE，以将小区A对应的半静态SRS去激活；基于小区B对应的时频域资源，向终端设备发送MAC CE，以激活小区B对应的半静态SRS，由此，可以有小区B为终端设备提供服务。
通过实施本公开实施例，网络设备首先向终端设备发送邻小区对应的SRS，之后基于邻小区或者服务小区对应的时频域资源，向终端设备发送第一MAC CE，激活或去激活服务小区或邻小区对应的半静态SRS。由此，网络设备通过MAC CE激活邻小区对应的半静态SRS之后，即可获取终端设备与邻小区之间的合适的上行波束对，进而可以由邻小区为终端设备提供服务。

请参见图13，图13是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由网络设备执行。如图13所示，该方法可以包括但不限于如下步骤：
步骤131，发送配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤131的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤132，发送第二MAC CE，其中，第二MAC CE用于指示邻小区及服务小区对应的多个非周期的SRS中被选中的SRS。
可选的，网络设备可以通过MAC CE中的多个bits来指示邻小区及服务小区对应的多个非周期的SRS中被选中的SRS。比如，邻小区及服务小区共对应N个非周期SRS，则MAC CE中可以至少包括与各个SRS对应的选择状态标识位T0～TN，Ti＝1表示其对应的第i个SRS资源集被选中，Ti＝0则表示其对应的第i个SRS资源集未被选中。举例来说，T0＝1,表示第一个SRS资源集被选中。
步骤133，基于服务小区对应的时频域资源，发送第二DCI，其中，第二DCI用于触发被选中的SRS。
可以理解的是，对应非周期的SRS，网络设备需要向终端设备发送DCI，对被选中的非周期SRS进行触发之后，终端设备才可以基于触发的SRS向邻小区及服务小区发送SRS。
本公开中，可以通过服务小区向终端设备先发送第二MAC CE，以从多个非周期SRS中选择部分SRS，进而再由服务小区向终端设备发送第二DCI，以触发被选中的SRS中的部分SRS，之后，终端设备即可基于被触发的SRS资源向邻小区或者服务小区发送SRS，以完成上行波束的测量。
举例来说，网络设备发送的配置信息中可以包含8个邻小区及服务小区对应的SRS，之后，网络设备再向终端设备发送第二MAC CE，以指示终端设备从8个SRS中选择4个SRS，最后再向终端设备发送第二DCI，以触发被选中的SRS。
通过实施本公开实施例，网络设备首先向终端设备发送邻小区对应的SRS，之后向终端设备发送第二MAC CE，以指示邻小区及服务小区对应的多个非周期的SRS中被选中的SRS，最后通过服务小区向终端设备发送第二DCI，以触发被选中的SRS。由此，通过服务小区发送的第二MAC CE及第二DCI，即可实现对邻小区及服务小区对应的多个非周期性SRS中的部分SRS的触发，从而实现了支持终端设备与邻小区之间的上行波束测量，为实现邻小区为终端设备提供服务提供了依据。
请参见图14，图14是本公开实施例提供的一种上行波束的测量方法的流程示意图,该方法由网络设备执行。如图14所示，该方法可以包括但不限于如下步骤：
步骤141，发送配置信息，其中，配置信息中包括邻小区对应的探测参考信号SRS。
其中，步骤141的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
步骤142，基于邻小区或服务小区对应的时频域资源，发送第三DCI，其中，第三DCI 用于触发服务小区与邻小区中任一小区对应的非周期SRS。
可以理解的是，对应非周期的SRS，网络设备需要向终端设备发送DCI，以触发邻小区或服务小区对应的非周期SRS，之后才可以基于触发的SRS资源向邻小区及服务小区发送SRS。
本公开中，邻小区及服务小区，可以通过各自的DCI向终端设备指示触发的非周期的SRS，之后，终端设备即可根据服务小区指示触发的SRS，完成服务小区的上行波束测量，并基于邻小区指示触发的SRS，完成邻小区的上行波束测量。
举例来说，服务小区通过向终端设备发送第三DCI，指示触发其对应的非周期性SRS资源集set#1被触发，而邻小区通过向终端设备发送第三DCI，指示触发其对应的非周期性SRS资源集set#5，则终端设备即可基于SRSset#1对应的资源，向服务小区发送SRS，以完成服务小区对应的上行波束测量，并基于SRSset#5对应的资源，向邻小区发送SRS，以完成邻小区对应的上行波束测量。
通过实施本公开实施例，网络设备首先向终端设备发送邻小区对应的SRS，之后基于邻小区或服务小区对应的时频域资源，发送第三DCI，以触发服务小区与邻小区中任一小区对应的非周期SRS。由此，服务小区及邻小区，可以各自触发其对应的非周期SRS，从而实现了终端设备与邻小区之间的上行波束测量，为实现邻小区为终端设备提供服务提供了依据。
