下文是与本发明方案相关联现有技术的描述。如无特别说明，具体实施例中与现有技术中相同术语的含义相同。
值得指出的是，本发明说明书中涉及的用户设备与终端设备含义相同，文中的UE也可以表示终端，后文中不做具体区分和限定。类似的，网络设备为与终端进行通信的设备，包括并不限于基站设备，gNB，eNB， 无线AP等，后文中不做具体区分和限定。
根据与网络的连接等情况不同，网络中的终端可分为三种状态，连接(connected)态，空闲(idle)态和非激活(inactive)态。连接态的用户与网络建立有无线连接，用于进行数据传输或相关的业务处理。空闲态和非激活态的用户与网络也保持一定的连接，比如需要监听网络发送的广播消息和寻呼消息，或进行相关的测量等。如果空闲或非激活态的终端没有信号需要接收或发送时，终端可以处于睡眠状态以节省功耗。根据不同的信道条件或所需要处理的业务等，终端还可以处于不同的睡眠模式，比如浅睡模式，用于较短时间内就会有新的信号要处理时的短暂休眠。再比如深睡模式，用于终端在较长时间内都没有新的信号要处理时，可以比浅睡模式进一步的减少终端功耗。一般的，在不影响业务功能的情况下，让终端更多的处于休眠模式可以有效地减少终端的功耗，从而提升用户的体验。空闲态和非激活态用户在很多方面的处理是类似的，为避免冗余，如不做特别说明，本发明相关文字中，针对空闲态的终端或网络的相关动作也可以应用于非激活态的终端。类似的，其他与空闲态有类似需求的终端状态也可以类比处理，不做一一详述。
终端接收数据信号时或之前，往往需要一些预处理。比如终端可进行自动增益控制(AGC)参数的调整，使得处理的数据在其合适的动态范围之内，以获得较好的处理效果。或者，终端需要进行时频跟踪，根据参考信号估计信号的时偏或频偏参数等，对要处理的信号或数据进行相应的修正，以获得较好的接收性能。终端还可以有一些其他的处理，以优化数据处理，改善用户体验等，这里不再一一描述。终端可利用网络发送的参考信号进行预处理。
网络给终端配置和发送参考信号，用于终端的信道测量，信道参数估计，移动性评估，空间参数估计等等，实现无线资源管理，辅助数据信号接收等功能。例如，终端可接收网络发送的同步参考信号进行AGC调整或时频参数的估计等。或者，终端可接收网络发送的CSI-RS信号进行信道测量或波束管理等。
网络配置和发送CSI-RS参考信号用于终端进行信道测量，波束管理 等功能。CSI-RS可以以CSI-RS资源的形式配置给UE，一个终端可以配置一个或多个CSI-RS资源。一个或多个CSI-RS还可以组成一个CSI-RS资源集，一个终端可以配置一个或多个资源集。每个CSI-RS资源中定义一个CSI-RS信号，可以包含多个配置参数，比如时频资源配置，功率配置，码分配置，QCL配置等的一项或多项。终端可根据配置的参数确定和接收CSI-RS信号，并用于测量或信号接收等功能。
根据一些配置参数，CSI-RS可分为多种类型，比如NZP-CSI-RS为非零功率的CSI-RS，也就是CSI-RS的发送功率不为零。根据配置周期不同，CSI-RS还可以分为周期，半永久和非周期的信号类型。周期CSI-RS即，在配置生效后，所关联的CSI-RS资源按一定的周期在时频资源上重复出现。半永久和非周期的CSI-RS资源则需要通过MAC-CE或DCI指示的方式进行激活。终端可根据不同CSI-RS的资源以及相关的报告指示等实现不同的功能。用于时频跟踪(Tracking)的CSI-RS信号又可称为TRS。本发明中统一以CSI-RS作为适用于本发明的不同类型或参数的CSI-RS的代称。
网络按一定的周期发送SSB信号，SSB包含多种参考信号，比如SSS和PSS等。网络可以使用波束或称空间滤波器进行信号的发送和接收，网络中所使用的波束可能是模拟波束或数字波束或两者的混合。网络使用相应的波束发送SSB，比如网络使用8个波束发送SSB，那么发送周期中的SSB可以编号为SSB0到SSB7，分别表示使用不同波束发送的SSB。终端可以根据不同的位置，选择最好的波束进行信号接收或发送，以实现较好的通信。网络也可以使用不同的波束和终端进行信号的收发以实现良好的通信效果。
NR中使用QCL参数表征不同信号之间的空间关系，也就是说使用满足QCL关系的两个信号具有一定的空间信道关联性。比如，终端配置了两个信号满足某种QCL类型关系，终端在处理这两个信号时可以使用相同的某个参数，或者可以由一个信号得到的参数应用到另一个信号的接收或发送。比如，QCL类型为QCL-typeA，可由一个信号得到的多普勒频移，多普勒扩展，平均时延，延迟扩展等参数应用于另一个信号， 或者说共享这些参数。又比如QCL类型为QCL-typeC，可由一个信号得到的一个信号多普勒频移，延迟扩展参数等参数。又比如QCL类型为QCL-typeD，可由一个信号得到的一个信号波束参数信息。其他还有若干QCL类型，用户在应用时可根据相关参数进行识别。用户也可以在更多个相互满足QCL关系的信号间进行相关参数的应用，不再一一描述具体的类型。某个信号的QCL信息的配置可以使用TCI-state参数组进行指示。TCI-state里面可以包含QCL的类型，满足QCL关系的另一个或多个信号，以及信号所在的小区或BWP信息等参数。TCI-state可使用TCI-stateID作为标识。具体的，应用到SSB的QCL，也就是如果某个信号和某个SSB波束满足QCL关系，则该信号和SSB的一些参数可以互相识别。
网络发送的CSI-RS信号可以使用波束进行发送，网络配置CSI-RS的TCI-state参数指示与其QCL的信号。比如，网络可以配置一个CSI-RS资源与某个SSB i满足QCL，终端可认为SSB i与该CSI-RS的某些信道参数相同。如果终端侧有其他信号与SSB i满足QCL，终端可以通过该CSI-RS的接收或测量获得相关参数，应用到该信号的接收。
网络中的用户需要按一定的规则检测网络发送的寻呼信息。网络给用户配置寻呼周期和寻呼帧等参数，用户根据配置参数在一定的时频资源上接收指示寻呼信息的PDCCH。终端还可以根据PDCCH中的指示信息进行相应的信号接收或处理，比如在PDCCH指示的时频资源上进行PDSCH的接收。由于基站不能确定所寻呼的用户的最佳接收波束是哪一个，因此基站在一个寻呼周期内，使用所有实际发送的SSB波束发送寻呼PDCCH给该用户，用户可根据自身的情况接收相关的PDCCH信息。例如，终端可根据PDCCH时频资源的位置和顺序等，确定寻呼周期内的某个SSB波束对应的PDCCH时频资源。类似的，终端在接收某个寻呼PDCCH时，也能够确定与其满足QCL关系的SSB波束的序号。网络中的其他信号也可能存在与寻呼PDCCH类似的情况，终端可根据显式或隐式的指示确定该信号与SSB波束的QCL关系，本发明中应用到寻呼PDCCH的方法也可以应用到该信号。
空闲态或非激活态的终端需要定期接收网络的广播或寻呼信息，或进行相关的测量。比如，在接收寻呼信息之前，终端可以根据自身的能力，信道条件等因素接收网络发送的参考信号，进行AGC，时频跟踪等处理，并接收相应的数据信号，从而获得良好的效果。由于各种内部或外部的因素，终端做这些预处理时需要从休眠模式唤醒的次数或持续时间不同。比如，信道条件较差时，相关的参考信号接收质量较差，或者终端的处理能力有限时，终端需要唤醒多次接收多个参考信号，以实现较好的接收效果。再比如，所配置的参考信号距离要接收的信号较远，终端也可能需要较多次的参考信号接收或者保持较长的活动时间以获得较好的接收效果。
空闲态或非激活态的终端可以利用SSB实现相关的AGC或时频参数估计。SSB的周期和时频位置往往是固定的，可能不能够满足用户接收信号并且降低功耗的要求，因此网络可以提供额外的参考信号用于终端接收，使得终端能够更快的获得所需要的参数或信息，从而减少唤醒的时间或次数，以实现更好的节能效果。网络可以配置CSI-RS信号用作空闲或非激活用户的参考信号。比如网络在SIB信息中配置一组非零功率的CSI-RS信号，用作空闲或非激活用户的参考信号。为了节省网络的功率消耗，网络可以使用给连接态用户发送的CSI-RS信号共享给空闲态用户使用。网络可以配置一个或多个CSI-RS资源给空闲态用户，其中的部分或全部资源同时可能也是给连接态用户使用的信号。如果连接态用户不再使用这些资源，网络可以根据不同的情况部分或全部关闭这些CSI-RS信号，以减少网络侧的功率消耗。是否发送或不发送这些CSI-RS信号取决于网络的实现。网络在发送CSI-RS资源的过程中，可能会根据连接态用户的调整或其他原因，使用不同的波束发送CSI-RS资源，这时，需要通知空闲态用户进行波束参数的调整或配置，使得空闲态用户能够正确的接收信号。也可能网络不通知空闲态用户，用户可以根据检测结果确实时间上CSI-RS的有效性。
空闲态终端接收网络的配置，确定一个或多个CSI-RS资源或资源集和其使用的参考信号。可选的，网络配置CSI-RS资源的一个或多个QCL 参考信号，终端根据网络的指示确定与CSI-RS资源或资源集满足QCL关系的参考信号。可选的，终端根据网络的指示确定与参考信号满足QCL关系的CSI-RS资源或资源集。可选的，终端根据网络的指示确定CSI-RS资源或资源集的有效时间。
另一方面，如果网络没有发送相应的指示，或者终端没有接收到指示来确定配置的CSI-RS使用的QCL参考信号，终端可以根据所配置的CSI-RS进行检测，如果检测到相关信号并满足条件，比如检测的信号强度超过预定的门限，或者检测的信号与某个SSB波束满足QCL关系，终端可确定在该信号的传输周期内该信号的可用性，以及该信号使用的QCL参考信号。
【实施例1】
图1是示出了根据本发明的实施例1的由用户设备执行的方法的流程图。
如图1所示，在步骤101，接收用于指示CSI-RS资源或资源集的指示信号。
然后，在步骤103，终端根据接收到的所述指示信号，确定与指示信号使用的参考信号满足QCL关系的CSI-RS资源或资源集。
可选的，终端确定指示信号中指示的CSI-RS资源或资源集与指示信号使用相同的QCL参考信号。可选的，终端接收指示信号中的CSI-RS的资源ID或资源集ID，终端确定所指示的CSI-RS，终端确定这些CSI-RS使用与指示信号相同的QCL参考信号。具体的示例，指示信号为寻呼PDCCH，终端接收寻呼PDCCH，指示终端使用ID为i的CSI-RS资源或资源集。终端根据PDCCH的参数可确定该PDCCH所使用的QCL参考信号为SSB j，终端可以确定CSI-RS资源或资源集i的CSI-RS与SSB j满足QCL关系。
可选的，当使用搜索空间0传输指示信号时，一个SSB波束可能对应两个相邻时隙上的指示信号时频位置，两个不同的SSB波束可能会对应到同一个指示信号时频位置。终端可根据指示信号的指示确定与其满足QCL关系的波束。示例的，指示信号为寻呼PDCCH，终端可根据 PDCCH中的指示确定所接收的PDCCH使用的哪一个SSB波束，也就是确定该PDCCH满足QCL关系的参考信号。示例的，使用1比特标识PDCCH所对应的SSB波束序号。比如使用0表示PDCCH与满足配置参数要求的第一个SSB波束满足QCL关系，使用1表示PDCCH与满足配置参数要求的第二个SSB波束满足QCL关系。终端可根据确定的SSB波束序号确定PDCCH所指示的CSI-RS资源或资源集的满足QCL关系的参考信号。
可选的，终端确定满足时间要求的CSI-RS资源使用的QCL参考信号。可选的，终端根据指示信号确定CSI-RS资源使用的QCL参考信号的时间要求。示例的，终端根据接收到指示信号所在的帧号P确定时间。终端确定时间为帧号P后第一个使用帧号SFN并满足(SFN+PF_offset)％T＝0的时隙。T为寻呼循环的周期。PF_offset为寻呼帧偏移参数。终端从该时隙起，确定所指示的CSI-RS资源使用的相关的QCL参考信号。可选的，终端根据指示信号和时间长度确定CSI-RS资源使用QCL参考信号的时间。示例的，终端确定网络指示的长度为kT，终端根据接收到指示信号所在的帧号P，确定满足P后第一个满足(SFN+PF_offset)％kT＝0的具有帧号SFN的时隙起，所指示的CSI-RS使用相关的QCL参考信号。k为时间长度参数，大于0的整数。％为取模运算。时间长度参数可以通过RRC信令或DCI的方式指示给终端。时间长度参数还可以通过预定义的方式指示给终端。
可选的，终端根据指示信号确定CSI-RS信号不使用QCL参考信号。示例的，UE根据配置或指示确定CSI-RS i使用SSB j作为QCL参考信号进行发送。UE在与SSB k满足QCL关系的PDCCH上收到指示，指示CSI-RS i使用SSB k作为QCL参考信号，终端确定在满足时间要求的资源上，CSI-RS i不使用SSB j作为QCL参考信号。
可选的，终端确定使用指示信号相同的QCL参考信号的CSI-RS信号不使用该QCL参考信号。示例的，UE根据配置或指示确定CSI-RS i对应的资源使用SSB j作为QCL参考信号。UE在SSB j的PDCCH上没有收到指示指示CSI-RS i对应的资源使用SSB j作为QCL参考信号进 行发送，终端确定在满足时间要求的资源上，CSI-RS i不使用SSB j作为QCL参考信号。
可选的，终端确定CSI-RS资源或资源集与指示信号使用相同的QCL参考信号。可选的，网络可配置若干个CSI-RS资源或资源集作为与SSB i满足QCL关系的候选信号集。网络可以从候选信号集中选择部分或全部使用SSB i作为QCL参考信号，并在使用SSB i做为QCL参考信号的指示信号上指示终端。网络使用指示信号指示使用的CSI-RS在候选信号集中的信息。可选的，使用位图指示，示例的，网络配置SSB i使用k个CSI-RS资源集作为候选信号集，并按其ID大小排序。终端接收的指示信息中可以使用一个有效长度为k比特的域，每个比特分别对应不同的候选CSI-RS资源或资源集。
可选的，终端根据指示消息确定CSI-RS使用相应的QCL参考信号。可选的，使用位图指示方法，比特位图从低位起分别对应排序的CSI-RS资源或资源集，如果指示信号中的CSI-RS或CSI-RS资源集对应的指示状态为1，终端确定该CSI-RS或CSI-RS资源集对应的CSI-RS使用与指示信号相同的QCL参考信号。如果，指示信号中的CSI-RS或CSI-RS资源集对应的指示状态为0，UE确定该CSI-RS或CSI-RS资源集对应的CSI-RS不使用与指示信号相同的QCL参考信号。类似的，也可以使用相反指示状态或排列次序不同的指示方法，不一一详述。
可选的，使用数量指示方法，示例的，网络配置SSB i使用K个CSI-RS资源集作为候选信号集，并按其ID大小排序。终端接收的指示信息中可以使用一个有效长度为ceil(log2(K))比特的域，指示所使用的CSI-RS资源集数量。ceil为向上取整运算，log2为以2为底的对数运算。如果指示信号中指示的候选信号数量为0，候选信号集中CSI-RS都不使用该参考信号作为QCL参考信号。如果指示的数量为k，参考信号候选资源中前k个资源使用与指示信号相同的QCL参考信号，其余CSI-RS资源不使用该QCL参考信号。
可选的，终端根据指示信号中的距离信息确定与指示信号使用相同QCL参考信号的CSI-RS资源或资源集。示例的，网络使用寻呼PDCCH 指示CSI-RS资源所使用的QCL信息。终端根据所指示的CSI-RS信号与寻呼PDCCH所在时隙或符号的距离确定该CSI-RS使用与PDCCH使用相同的QCL参考信号，所述的距离可以是时隙数，时间单位或符号数等。所述的距离也可以是通过预定义的或配置的表中的序号所代表的时隙数，时间单位或符号数等。
示例的，距离信息使用时隙数，如果指示信号与CSI-RS使用相同的子载波间隔参数和循环前缀长度，则两者使用的时隙单位相同。如果两者使用的子载波检测参数或循环前缀长度不同，两者使用的时隙单位不同，终端可确定使用较小的子载波检测参数对应的时隙单位作为距离的参考。可选的，终端确定与寻呼PDCCH所在时隙满足指示的时隙距离的时隙为使用相同QCL参考信号的CSI-RS资源所在时隙。可选的，终端确定与寻呼PDCCH所在时隙满足指示的时隙距离的时隙使用相同QCL参考信号的CSI-RS资源集中CSI-RS资源的最后一个时隙。可选的，终端确定与寻呼PDCCH所在时隙满足指示的时隙距离的时隙为使用相同QCL参考信号的CSI-RS资源所在的第一个时隙。
