本公开的一些实施例提供了一种非周期信道状态信息参考信号配置方法，应用于网络设备侧，如图2所示，该方法可以包括以下步骤：
步骤21：获取终端能力信息。
其中，终端能力信息，或称为终端性能(UE capability)信息，用于指示终端所支持的数据处理能力(如上传速率、下载速率等)、最大空分复用(如所支持的天线端口数等)、调制编码能力等。该终端能力信息可以是终端发送给网络设备的。终端能力信息中包括多个用于表征不同性能类型的参数，参数的取值表示终端在相应性能类型的支持能力。终端能力信息包括：非周期信道状态信息参考信号CSI-RS的波束切换时间(aperiodic CSI-RS beam switching timing，或AP-CSI-RS beam switching timing，或A-CSI-RS beam switching timing)等参数。该参数指的是在触发非周期CSI-RS的DCI与发送该非周期CSI-RS之间的最小时间长度，例如DCI的最后一个符号与非周期CSI-RS的第一个符号之间的时间长度或符号数。其中，该参数的取值(能力参数)与子载波间隔有关，该参数的取值包括{14，28，48，224，336}。
步骤22：根据非周期信道状态信息参考信号CSI-RS的测量行为以及终端能力信息，确定非周期CSI-RS的门限值。
其中，非周期CSI-RS的测量行为指的是将非周期CSI-RS用于何种测量，测量行为包括但不限于：波束测量和CSI测量。也就是说，非周期CSI-RS可以用于波束测量，也可以用于CSI测量。根据非周期CSI-RS的测量行为以及终端的终端能力信息联合确定非周期CSI-RS的门限值。该门限值指的是非周期CSI-RS的调度偏移门限的值。所述调度偏移指的是在触发非周期CSI-RS的DCI与发送该非周期CSI-RS之间的时间长度。
步骤23：向终端发送门限值。
网络设备在确定非周期CSI-RS的调度偏移门限的门限值后，将该值指示给终端，以使终端根据该门限值确定非周期CSI-RS的空间信息(如波束)， 以便于非周期CSI-RS的接收和后续的测量。
下面本实施例将结合不同场景，对步骤22的实现做进一步说明。
场景一、在非周期CSI-RS的测量行为为波束测量的情况下，即非周期CSI-RS用于波束测量的情况。
步骤22包括：将终端能力信息中特定参数指示的值确定为门限值。也就是说，在非周期CSI-RS用于波束测量的场景下，网络设备可将终端上报的特定参数的取值确定为非周期CSI-RS的调度偏移门限的值。
其中，特定参数为非周期CSI-RS的波束切换时间，假设终端上报的非周期CSI-RS的波束切换时间为{14，28，48，224，336}中的一项，那么将终端上报的波束切换时间的具体取值确定为非周期CSI-RS的调度偏移门限的值。例如终端上报的波束切换时间为14，则将14确定为门限值；若上报的波束切换时间为224，则将224确定为门限值。
场景二、在非周期CSI-RS的测量行为为CSI测量的情况下，即非周期CSI-RS用于CSI测量的情况。
当终端上报的非周期CSI-RS波束切换时间的取值较大时，若采用较大取值作为调度偏移门限时，对于CSI测量的非周期CSI-RS，终端不需要过长的时间来实现接收非周期CSI-RS的波束切换，将导致终端测量DCI指示的指定波束上的CSI的延迟过大，甚至无法测量到DCI指示的指定波束上的CSI。因此，步骤22包括：若终端能力信息中特定参数指示的值大于预设值时，将以下取值中的一个确定为门限值；其中，该取值为：
特定参数的可选值中小于预设值的最大值，
特定参数的可选值中小于预设值的最小值，
小于预设值的指定值。该指定值可以是网络设备指示的，也可以是预定义的(如协议约定、厂商预配置等)。
其中，预设值可以为非周期CSI-RS的触发偏移可取的最大值，或者，预设值可以为特定参数的第M个可选值至第N个可选值范围内的某个值。其中，特定参数可以是非周期CSI-RS的波束切换时间，特定参数的可选值为{14，28，48，224，336}，那么预设值可以是第3个至第4个可选值范围内的某个值，即预设值为大于48小于224的某个值。
进一步地，当预设值为大于或等于48且小于224的某个值时，若终端能力信息中非周期CSI-RS的波束切换时间指示的值大于该预设值时，将以下取值中的一个确定为门限值；其中，该取值为：
特定参数的可选值{14，28，48，224，336}中小于预设值的集合{14，28，48}中的最大值，即48，
特定参数的可选值{14，28，48，224，336}中小于预设值的集合{14，28，48}中的最小值，即14，
小于预设值的指定值，假设预设值为180，指定值可以为80。该指定值可以是网络设备指示的，也可以是预定义的(如协议约定、厂商预配置等)。
此外，在场景二下，若终端能力信息中特定参数指示的值小于或等于预设值时，将终端上报的特定参数的取值确定为非周期CSI-RS的调度偏移门限的值。
其中，特定参数为非周期CSI-RS的波束切换时间，假设终端上报的非周期CSI-RS的波束切换时间为{14，28，48}中的一项，那么将终端上报的波束切换时间的具体取值确定为非周期CSI-RS的调度偏移门限的值。例如终端上报的波束切换时间为14，则将14确定为门限值；若上报的波束切换时间为48，则将48确定为门限值。
在步骤22之后，该方法还进一步包括：根据门限值，确定非周期CSI-RS的发送波束，这样可保证非周期CSI-RS的正常发送。
进一步地，根据门限值，确定非周期CSI-RS的发送波束的步骤包括：
在非周期CSI-RS的触发偏移小于门限值时，根据默认准共址QCL信息，确定发送波束；也就是说，当触发偏移小于确定的门限值时，网络设备使用默认QCL假设来确定非周期CSI-RS的发送波束。
或者，在非周期CSI-RS的触发偏移大于或等于门限值时，根据下行控制信息DCI中传输配置指示(Transmission Configuration Indication，TCI)状态(state)所对应的QCL信息，确定发送波束；也就是说，当触发偏移大于或等于确定的门限值时，网络设备根据DCI中TCI状态对应的QCL信息来确定非周期CSI-RS的发送波束。
进一步地，在根据门限值，确定非周期CSI-RS的发送波束的步骤之后， 包括：在发送波束上，发送非周期CSI-RS，以使终端完成相应的测量。
进一步地，网络设备在确定非周期CSI-RS的测量行为后，还包括：向终端发送测量行为信息，该测量行为信息用于指示非周期CSI-RS的测量行为，这样终端在接收到非周期CSI-RS之后，可按照测量行为信息的指示，基于非周期CSI-RS进行波束测量或CSI测量。非周期CSI-RS的测量行为信息可以是由网络设备显式或者隐式发送给终端。例如，网络设备在配置非周期CSI-RS资源集的参数时，如果参数中包括repetition(字段)，则表示所述非周期CSI-RS资源集是用于波束测量；如果参数中不包括repetition(字段)，则表示非周期CSI-RS资源集是用于CSI测量。

以上实施例从网络设备侧介绍了本公开的非周期信道状态信息参考信号配置方法，下面本实施例将结合附图对终端侧的非周期信道状态信息参考信号配置方法做进一步介绍。
如图5所示，本公开的一些实施例的非周期信道状态信息参考信号配置方法，应用于终端侧，包括以下步骤：
步骤51：向网络设备发送终端能力信息。
其中，终端能力信息，或称为终端性能(UE capability)信息，用于指示终端所支持的数据处理能力、最大空分复用、调制编码能力等。终端能力信息中包括多个用于表征不同性能类型的参数，参数的取值表示终端在相应性能类型的支持能力。终端能力信息包括：非周期信道状态信息参考信号CSI-RS的波束切换时间等参数。该参数指的是在触发非周期CSI-RS的DCI与发送该非周期CSI-RS之间的最小时间长度，例如DCI的最后一个符号与非周期CSI-RS的第一个符号之间的时间长度或符号数。其中，该参数的取值(能力参数)与子载波间隔有关，该参数的取值包括{14，28，48，224，336}。
步骤52：接收非周期信道状态信息参考信号CSI-RS的门限值，其中，门限值是根据非周期CSI-RS的测量行为和终端能力信息确定的。
其中，该门限值指的是非周期CSI-RS的调度偏移门限的值。测量行为包括但不限于：波束测量和CSI测量。也就是说，非周期CSI-RS可以用于波束测量，也可以用于CSI测量。
步骤53：根据门限值，确定非周期CSI-RS的接收波束。
终端根据该门限值确定非周期CSI-RS的空间信息(如波束)，以便于非周期CSI-RS的接收和后续的测量。
其中，在测量行为为波束测量的情况下，门限值为终端能力信息中特定参数指示的值。对应于上述网络设备侧实施例的场景一，在此不再赘述。
进一步地，在测量行为为CSI测量，终端能力信息中特定参数指示的值大于预设值的情况下，门限值为以下取值中的一个；其中，取值为：
特定参数的可选值中小于预设值的最大值，
特定参数的可选值中小于预设值的最小值，
小于预设值的指定值。
其中，该门限值的确定对应与于上述网络设备侧实施例的场景二，在此不再赘述。
值得指出的是，门限值可以是终端从网络设备侧接收到的，也可以是终端按照预设规则确定的，其确定方式可以与网络设备侧确定门限值的方式相同。
例如，在非周期CSI-RS的测量行为为波束测量的情况下，可将终端上报的特定参数的取值确定为非周期CSI-RS的调度偏移门限的值。上述特定参数可以为非周期CSI-RS的波束切换时间，其可选值可以为{14，28，48，224，336}。假设终端上报的非周期CSI-RS的波束切换时间为{14，28，48，224，336}中的一项，那么将终端上报的波束切换时间的具体取值确定为非周期CSI-RS的调度偏移门限的值。例如终端上报的波束切换时间为14，则将14确定为门限值；若上报的波束切换时间为224，则将224确定为门限值。
又例如，在非周期CSI-RS的测量行为为CSI测量的情况下，若终端上报的特定参数的值大于预设值时，将以下取值中的一个确定为门限值；其中， 该取值为：
特定参数的可选值中小于预设值的最大值，
特定参数的可选值中小于预设值的最小值，
小于预设值的指定值。该指定值可以是网络设备指示的，也可以是预定义的(如协议约定、厂商预配置等)。
其中，预设值可以为非周期CSI-RS的触发偏移可取的最大值，或者，预设值可以为特定参数的第M个可选值至第N个可选值范围内的某个值。又例如，在非周期CSI-RS的测量行为为CSI测量的情况下，若终端上报的特定参数的值小于或等于预设值时，将终端上报的特定参数的取值确定为非周期CSI-RS的调度偏移门限的值。
进一步地，步骤53包括：
在非周期CSI-RS的触发偏移小于门限值时，根据默认准共址QCL信息，确定接收波束；也就是说，当触发偏移小于确定的门限值时，终端使用默认QCL假设来确定非周期CSI-RS的接收波束。
在非周期CSI-RS的触发偏移大于或等于门限值时，根据下行控制信息DCI中传输配置指示TCI状态所对应的QCL信息，确定接收波束。也就是说，当触发偏移大于或等于确定的门限值时，终端根据DCI指示的TCI状态对应的QCL信息来确定非周期CSI-RS的接收波束。
步骤53之后，还包括：在接收波束上，接收并测量非周期CSI-RS，以得到与测量行为对应的测量结果。假设测量行为为波束测量，终端在接收波束上接收非周期CSI-RS，并基于该非周期CSI-RS进行波束测量，得到相应的测量结果。假设测量行为为CSI测量，终端在接收波束上接收非周期CSI-RS，并基于该非周期CSI-RS进行CSI测量，得到相应的测量结果。
进一步地，本实施例中测量行为可以是网络设备配置的测量行为信息指示的，在接收波束上，接收并测量非周期CSI-RS，以得到与测量行为对应的测量结果的步骤之前，还包括：接收用于指示非周期CSI-RS的测量行为的测量行为信息；测量行为信息用于指示波束测量或CSI测量。
本公开的一些实施例的非周期信道状态信息参考信号配置方法中，终端在触发非周期CSI-RS时，接收网络设备发送的非周期CSI-RS的门限值，由 于该门限值是根据终端能力信息以及非周期CSI-RS的测量行为确定的，终端根据该门限值可正确确定非周期CSI-RS的波束信息，保证信号的正常传输和测量，从而可以提高通信的可靠性和有效性。
以上实施例介绍了不同场景下的非周期信道状态信息参考信号配置方法，下面将结合附图对与其对应的终端做进一步介绍。
如图6所示，本公开的一些实施例的终端600，能实现上述实施例中向网络设备发送终端能力信息；接收非周期信道状态信息参考信号CSI-RS的门限值，其中，门限值是根据非周期CSI-RS的测量行为和终端能力信息确定的；根据门限值，确定非周期CSI-RS的接收波束方法的细节，并达到相同的效果，该终端600具体包括以下功能模块：

其中，在测量行为为波束测量的情况下，门限值为终端能力信息中特定参数指示的值。

其中，终端600还包括：
测量模块，用于在接收波束上，接收并测量非周期CSI-RS，以得到与测量行为对应的测量结果。
其中，终端600还包括：
第二接收模块，用于接收用于指示非周期CSI-RS的测量行为的测量行为信息；测量行为信息用于指示波束测量或CSI测量。
值得指出的是，本公开的一些实施例的终端在触发非周期CSI-RS时，接收网络设备发送的非周期CSI-RS的门限值，由于该门限值是根据终端能力信息以及非周期CSI-RS的测量行为确定的，终端根据该门限值可正确确定非周期CSI-RS的波束信息，保证信号的正常传输和测量，从而可以提高通信的可靠性和有效性。
