为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
如前所述，对于RRC-Connected的终端设备，可以例如通过配置的CSI-RS、TRS等参考信号进行时频跟踪。
●NR系统中的CSI-RS和TRS
NR中的CSI-RS主要用于以下几个方面：
1)获取信道状态信息。用于调度、链路自适应以及和MIMO相关的传输设置。
2)用于波束管理。UE和基站侧波束的赋形权值的获取，用于支持波束管理过程。
3)时频追踪。系统中可以通过设置TRS来实现。
4)用于移动性管理。系统中通过对本小区和邻小区的CSI-RS信号获取跟踪，来完成终端设备的移动性管理相关的测量需求。
5)用于速率匹配。通过零功率的CSI-RS信号的设置来完成数据信道的资源元素(Resource Element，RE)级别的速率匹配的功能。
在NR系统中，为了能够灵活支持不同天线的虚拟化映射以及码本的设计，并考虑到实际的应用部署场景，NR支持的端口数可以为1、2、4、8、12、16、24、32。其中，8、12、16、24、32端口图样均由2或4端口图样组合而成。不同天线端口的CSI-RS通过频分、时分或码分的方式复用组成CSI-RS图样。每x个端口CSI-RS图样基本单元由一个物理资源块(Physical Resource Block，PRB)内频域上相邻的Y个RE和时域上相邻的Z个符号组成，如下所示。
1端口：(Y,Z)＝(1,1)
2端口：(Y,Z)＝(2,1)
4端口：(Y,Z)＝(4,1)或(2,2)
例如，12天线端口的CSI-RS定义了两种图样，如图2所示，左侧的图样1为包含6个码分复用CDM2的组，每个CDM2的组包含1个符号上的2个RE，两个天线端口的CSI-RS进行码分复用。右侧的图样2为包含3个CDM4的组，每个CDM4的组包含2个符号上的4个RE，4个天线端口的CSI-RS进行码分复用。
NR支持周期、半持续和非周期的资源配置。CSI-RS是UE特定的配置，考虑到CSI-RS的资源开销问题，网络在配置CSI-RS时，往往将一套CSI-RS的资源配置给多个UE进行共享。UE在配置的CSI-RS占据的RE上，进行速率匹配。例如，如果PDSCH的资源分配包含的RE中包括了网络配置的CSI-RS的RE，则在这些RE上进行打孔，不承载PDSCH。
为了实现UE对于下行信道的时偏和频偏进行跟踪和补偿，NR系统定义了新的用于时频跟踪的参考信号，称为TRS信号。它实质上也是一种CSI-RS。
NR系统支持周期性和非周期TRS。周期性TRS为一个包含多个周期性CSI-RS资源的CSI-RS资源集合，且此资源集合配置中包含一个高层信令指示此资源集合用作TRS。为了达到一定的时间跟踪范围，每个CSI-RS资源为一个密度为3的1端口CSI-RS资源。同时为了达到频率跟踪范围，一个时隙中的TRS符号间隔为4。TRS只支持1个端口，所以在CSI-RS资源集中配置的所有NZP CSI-RS资源包含相同的端口索引并对应同一个天线端口。
对于低频段，高层可以给终端设备配置一个包含4个周期CSI-RS资源的CSI-RS资源集合，这4个资源分布在两个连续时隙内，每个时隙包含两个周期CSI-RS资源，并且这两个时隙中的CSI-RS资源在时域中的位置相同。
对于高频段，高层可以给终端设备配置一个分布在1个时隙上包含2个周期CSI-RS资源的CSI-RS资源集合，或者配置一个分布在2个连续时隙上包含4个周期CSI-RS资源的CSI-RS资源集合，并且这 两个时隙中的CSI-RS资源在时域中的位置相同。
系统中有许多非周期时间和一些周期时间不能与周期的TRS对齐，会给UE的解调带来严重的影响。此外，在高频段的波束改变后，也不能接受长时间无法根据TRS进行时频跟踪。因此需要在周期TRS的基础上，引入非周期的TRS信号。非周期TRS与周期TRS的结构相同，如采用相同的带宽，具有相同的频域位置和一个TRS突发(burst)中具有相同的时隙数量。考虑与非周期CSI-RS的触发方法的一致性，NR中使用下行控制信令(Downlink control information，DCI)触发非周期的TRS。
●终端节能技术
在NR技术的演进中，对终端设备的节电提出了更高的要求。例如对于现有的不连续接收(Discontinuous Reception，DRX)机制，在每个运行持续时间(on duration)期间，终端设备需要不断检测物理下行控制信道(Physical Downlink Control CHannel，PDCCH)来判断基站是否调度发给自己的数据传输。但是对于大部分终端设备来说，可能在很长一段时间没有接收数据传输的需要，但是仍然需要保持定期的唤醒机制来监听可能的下行传输，对于这类终端设备，节电有进一步优化的空间。对于RRC空闲状态下的终端设备接收寻呼消息的情况也是类似。
在R16标准中，引入了节能信号，以实现进一步的节能。节能信号与DRX机制结合使用，终端在DRX ON duration之前接收节能唤醒信号的指示。当终端在一个DRX周期有数据传输时，节能唤醒信号“唤醒”终端，以在DRX On duration期间监听PDCCH；否则，当终端在一个DRX周期没有数据传输时，节能唤醒信号不“唤醒”终端，终端在DRX On Duration期间不需要监听PDCCH。相比现有DRX机制，在终端没有数据传输时，终端可省略DRX On duration期间PDCCH监听，从而实现节能。终端在DRX On duration之外的时间被称为非激活时间，在DRX On Duration的时间被称为激活时间。通过节能信号指示终端在DRX On Duration是否监听PDCCH的过程如图3所示。
·寻呼
在NR系统中，网络可以向空闲状态(idle)和连接状态(RRC-Connected)的终端设备发送寻呼。寻呼过程可以由核心网触发或者基站触发，用于向处于空闲状态的终端设备发送寻呼请求，或者用于通知系统信息更新，以及通知终端设备接收ETWS(地震海啸预警信息)以及CMAS(商用移动预警服务)等信息。基站接收到核心网的寻呼消息后，解读其中的内容，得到该UE的跟踪区域标识(Tracking Area Identity，TAI)列表(TA，list)，并在其下属于列表中的跟踪区域的小区进行空口的寻呼。寻呼消息的核心网域不会在基站解码，而是透传给终端设备。基站收到核心网的寻呼消息之后，将寻呼时机相同的终端设备的寻呼消息汇总成一条寻呼消息，通过寻呼信道传输给相关终端设备。终端设备通过系统消息接收寻呼参数，结合自身的设备ID(例如UE_ID)来计算寻呼时机，在相应的时间接收寻呼消息。寻呼消息通过物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)承载，终端设备通过检测用寻呼无线网络临时标识(Paging RNTI Radio Network Tempory Identity，P-RNTI)加扰的PDCCH来获得寻呼指示信息，从而接收寻呼消息。空闲状态的终端设备会通过DRX的方式省电，终端设备从SIB2获取DRX相关信息。在一个DRX周期中的寻呼帧上的寻呼时机监听通过P-RNTI加扰的PDCCH来接收寻呼消息，如图4所示。
如上所述，对于RRC-Connected的终端设备，可以例如通过配置的CSI-RS、TRS等参考信号进行时频跟踪。对于空闲状态或非激活状态的终端设备，该终端设备在其对应的寻呼时机检测寻呼之前，也需要进行时频跟踪和自动增益控制，由于空闲状态或非激活状态的终端设备没有被配置CSI-RS、TRS等参考信号，所以3GPP R17标准考虑为空闲状态或非激活状态的终端设备引入这样的参考信号。但是如何为空闲状态或非激活状态的终端设备指示CSI-RS、TRS的资源，还没有解决方案。
因此，如何为空闲状态或非激活状态的终端设备指示例如CSI-RS、TRS等参考信号资源，是亟需解决的技术问题。
本申请提供了相应的解决方案。
图5是根据本申请一实施例的信息指示方法的示意性流程图。该方法可选地可以应用于图1所示的通信系统中的终端设备和网络设备，但并不仅限于此。该方法包括以下内容的至少部分内容。
S210，网络设备向空闲状态或非激活状态的终端设备发送用于为所述终端设备指示参考信号资源的配置信息。
其中，所述配置信息中包含所述参考信号资源的准共址(quasi co-located，QCL)信息。
S220，终端设备接收用于为空闲状态或非激活状态的所述终端设备指示参考信号资源的配置信息。
在本实施例中，上述的参考信号资源的配置信息可以是通过系统消息来配置的。
另外，这里的“参考信号资源”可以包括CSI-RS、TRS等参考信号的资源。
由此，通过根据本实施例的上述信息指示方法，能够为空闲状态或非激活状态的终端设备指示例 如CSI-RS、TRS等的参考信号资源的配置信息。
可选地，根据本申请实施例，可以通过传输配置指示状态TCI-state信息来指示所述QCL信息，所述TCI-state信息可以通过系统消息来指示。
也就是说，在本申请实施例中，与现有技术不同，可以通过系统消息来指示TCI-state信息，并且可以通过TCI-state信息来指示所述QCL信息。
所述系统消息例如可以为tci-StatesToAddModList信息。具体地，系统消息可以是系统信息块SIB1-14中的任意一个或者多个。
以下用代码示例出根据本申请实施例的CSI-RS资源的配置信息，其中包括了该CSI-RS资源的QCL信息，即qcl-InfoPeriodicCSI-RS，该QCL信息可以通过TCI-state信息来指示。

在本申请的实施例中，如上所述，为了使空闲状态或非激活状态的终端设备获得CSI-RS资源或CSI-RS资源集合的QCL信息，可以通过系统消息指示TCI-state的配置信息，例如tci-StatesToAddModList信息。具体的，系统消息可以是SIB1-14中的任意一个或者多个。
其中，TCI-state的配置如下，其中bwp-Id表示当提供QCL信息的参考信号为CSI-RS时，该CSI-RS所在的带宽分段BWP。对于空闲状态或非激活状态的终端设备，只有初始带宽分段(initial BWP)，且不会有其他的CSI-RS资源的配置，因此，系统消息中指示的TCI-state信息可以不用指示两种可能的参考信号，而是只包含同步信号块SSB-index的指示，即只用SSB-index指示TCI-state关联的参考信号。

优选地，系统消息中指示的TCI-state配置的最大数量可以与SSB-index的数量数量，例如可以与SSB-index的数量相等。SSB-index的数量可以与小区所在的频段有关，例如可以为4、8、64。在高频段，SSB的数量可能更多，例如128。而现有技术中，TCI-state配置的最大数量maxNrofTCI-States＝128。
所述系统消息中的TCI-state信息的最大数量与所述SSB-index的数量相关。
可选地，所述TCI-state信息中的TCI-StateId与SSB-index具有对应关系。
如前所述，在现有技术中，对于RRC-Connected状态的终端设备，可以通过配置的CSI-RS、TRS等参考信号进行时频跟踪。而对于空闲或非激活状态的终端设备，该终端设备在其对应的寻呼时机检测寻呼之前，也需要进行时频跟踪和自动增益控制AGC。
具体地，对于空闲或非激活状态的终端设备使用的TRS、CSI-RS等资源，其与为RRC-Connected状态的终端设备配置的TRS、CSI-RS等资源往往是共用的，这样可以减少TRS、CSI-RS等资源的开销。但是，目前的CSI-RS资源的配置信息中的QCL信息，即TCI-state只有RRC-Connected状态的终端设备才会被配置，空闲或非激活状态的终端设备无法获得TCI-state的配置信息，因此无法获得CSI-RS资源的QCL信息。现有技术中，TCI-state的配置信息通过为RRC-Connected状态的终端设备指示的UE特定(UE specific)的配置信息PDSCH-Config来获得，空闲或非激活状态的终端设备只能获得公共的配置信息，并不能获得UE特定的配置信息。
由于空闲或非激活状态的终端设备没有被配置CSI-RS、TRS等参考信号，所以无法实现时频跟踪等功能，进一步地，即便为空闲或非激活状态的终端设备配置这样的参考信号，现有技术也没有解决为空闲或非激活状态的终端设备指示这样的参考信号的资源的技术问题。
而本申请通过由网络设备向空闲状态或非激活状态的终端设备发送用于为所述终端设备指示参考 信号资源的配置信息，并且在所述配置信息中包含所述参考信号资源的QCL信息，能够解决上述技术问题。由此使得空闲状态或非激活状态的终端设备能够实现上述的例如时频跟踪和自动增益控制AGC等功能。
由此，在本申请中，可以通过系统消息为空闲或非激活状态的终端设备配置TRS、CSI-RS资源，用于空闲或非激活状态的终端设备进行时频跟踪和自动增益控制AGC；并且，对于TRS、CSI-RS等参考信号资源的配置，可以通过TCI-state信息来指示CSI-RS资源或CSI-RS资源集合的QCL信息。
对于连接状态的UE，TRS、CSI-RS资源的TCI-state信息包括关联的参考信号和QCL类型。对于空闲或非激活状态的终端设备而言，可以不需要TCI-state信息中详细的QCL信息，如上面的实施例所给出的，关联的参考信号可以只有同步信号块SSB。
进一步地，可以使得QCL类型预定义，比如，可以将QCL类型预定义为N(N为大于等于2的整数)个类型中的任意一个或者多个。例如，预定义类型可以为typeA,typeB,typeC,typeD中的任意一个或者多个。通过这样对于QCL类型进行预定义，就不需要在TCI-state信息中再进行具体的指示。
可选地，根据本申请实施例，可以通过预定义的TCI-state信息来指示所述QCL信息。
可选地，所述预定义TCI-state信息中指示的QCL类型为预定义的。
本实施例中，当TRS、CSI-RS资源的配置信息中的TCI-state表示的QCL信息为预定义时，则不需要在系统消息中指示TCI-state配置信息，即TRS、CSI-RS资源配置信息中的TCI-state代表的QCL信息为预定义的。
可选地，所述预定义TCI-state信息中指示的QCL类型被预定义为N个类型中的任意一个或者多个，其中N为大于等于2的整数。
可选地，，所述预定义TCI-state信息中指示的QCL类型可以为通过TCI-stateId来预定义的。
也就是说，例如可以通过使用TCI-StateId来预定义所述预定义TCI-state信息中指示的QCL类型。
TCI-StateId可以与SSB-index具有对应关系，例如TCI-StateId可以等于SSB-index或者其整数倍。当空闲或非激活状态的终端设备收到TRS、CSI-RS资源的配置信息之后，可以根据该配置信息中的TCI-stateId、以及TCI-stateId所预定义的QCL信息，得到关联的SSB-index和QCL类型信息。
可选地，在所述TCI-state信息和所述预定义TCI-state信息中可以用同步信号块索引SSB-index来指示与所述QCL信息相关联的信号。
可选地，所述系统消息中的TCI-state或预定义TCI-state信息的最大数量与所述SSB-index的数量相关。
可选地，所述预定义TCI-state信息至少指示相对应的预定义同步信号块索引SSB-index信息和/或相对应的预定义QCL类型信息。
根据本实施例，通过使用预定义的TCI-state信息来指示所述QCL信息，并且通过这样对于QCL类型进行预定义，就不需要在TCI-state信息中再进行具体的指示。
可选地，根据本申请实施例，可以通过同步信号块(Synchronization Signal Block,SSB)索引SSB-index信息来指示所述QCL信息。
可选地，可以通过以下至少之一来指示QCL类型：
用于表示QCL类型的QCL-Type信息；
参考信号资源，其中所述参考信号资源至少对应于预定义的QCL类型；以及
参考信号资源的配置信息，其中所述参考信号资源的配置信息至少对应于预定义的QCL类型。
其中，QCL-Type为新定义的域(field)，用于表示QCL类型，以便与同步信号块(Synchronization Signal Block,SSB)索引SSB-index信息一起来指示所述QCL信息。
在本实施例中，在指示QCL信息时，不再通过TCI-state，而是直接通过SSB-index信息来指示QCL信息。如下面的代码所示，其中包括SSB-index信息和QCL-Type信息。

这里，本申请不限于上述的几个示例方式，而是还可以通过其他的方式来为空闲状态或非激活状态的终端设备指示QCL信息。
可选地，如图7所示，根据本申请实施例的信息指示方法还可以包括：
S230，响应于接收到所述配置信息，处于空闲状态或非激活状态的所述终端设备基于所述配置信息，确定关联的参考信号资源的SSB-index信息和/或QCL类型信息。
具体地，例如，响应于接收到所述配置信息，处于空闲状态或非激活状态的所述终端设备可以基于所述TCI-state信息，确定关联的参考信号资源的SSB-index信息和/或QCL类型信息。
再例如，响应于接收到所述配置信息，处于空闲状态或非激活状态的所述终端设备可以基于所述预定义TCI-state信息，确定关联的参考信号资源的SSB-index信息和/或QCL类型信息。
又例如，响应于接收到所述配置信息，处于空闲状态或非激活状态的所述终端设备可以基于所述QCL-Type信息，确定相应的QCL类型信息。
还例如，响应于接收到所述配置信息，处于空闲状态或非激活状态的所述终端设备可以基于所述配置信息或者所述配置信息中指示的参考信号资源，确定相应的QCL类型信息。
可选地，所述网络设备可以为处于空闲状态或非激活状态的终端设备确定用于为所述终端设备指示参考信号资源的配置信息。
可选地，所述网络设备可以基于关联的参考信号资源的SSB-index信息和/或QCL类型信息来为处于空闲状态或非激活状态的所述终端设备设置所述配置信息。
具体地，例如，所述网络设备可以基于关联的参考信号资源的SSB-index信息和/或QCL类型信息来为处于空闲状态或非激活状态的所述终端设备设置所述TCI-state信息。
再例如，所述网络设备可以基于关联的参考信号资源的SSB-index信息和/或QCL类型信息来为处于空闲状态或非激活状态的所述终端设备设置所述预定义TCI-state信息。
又例如，所述网络设备可以基于相应的QCL类型信息来为处于空闲状态或非激活状态的所述终端设备设置所述QCL-Type信息。
还例如，所述网络设备可以基于相应的QCL类型信息来为处于空闲状态或非激活状态的所述终端设备设置所述配置信息或者所述配置信息中指示的参考信号资源。
可选地，根据本申请实施例，当通过PDCCH来承载处于空闲状态或非激活状态的所述终端设备可用的参考信号资源或传输时机时，PDCCH的监听时机关联的QCL信息和所述PDCCH指示的可用的参考信号资源的QCL信息可以具有对应关系。
可选地，根据本申请实施例，PDCCH的监听时机关联的QCL信息所对应的SSB-index与所述PDCCH指示的可用的参考信号资源的QCL信息对应的SSB-index可以具有对应关系。
可选地，根据本申请实施例，PDCCH的监听时机关联的QCL信息对应的SSB-index与所述PDCCH指示的可用的参考信号资源的QCL信息对应的SSB-index可以相同或者具有准共址QCL关系。
可选地，根据本申请实施例，承载寻呼早期指示PEI的参考信号资源的QCL信息和所述PEI所指示的可用的参考信号资源的QCL信息可以具有对应关系。
可选地，根据本申请实施例，承载寻呼早期指示PEI的参考信号资源的QCL信息对应的SSB-index和所述PEI所指示的可用的参考信号资源的QCL信息对应的SSB-index可以具有对应关系。
可选地，根据本申请实施例，承载寻呼早期指示PEI的参考信号资源的QCL信息对应的SSB-index和所述PEI所指示的可用的参考信号资源的QCL信息对应的SSB-index可以相同或者具有准共址QCL关系。
具体地，PDCCH的监听时机对应的QCL信息和该PDCCH所指示的可用TRS、CSI-RS资源的QCL信息可以具有对应关系。
为了减少空闲状态或非激活状态的终端设备的耗电，当为空闲状态或非激活状态的终端设备 配置了TRS、CSI-RS资源之后，终端设备并不是在所有的参考信号传输时机都接收。通过物理层信令可以指示可用的TRS、CSI-RS资源，TRS、CSI-RS资源可用的时间段，或者传输时机。例如图8所示，可以通过下行控制信令DCI携带该指示信息。
该DCI可以是承载寻呼指示信息的寻呼DCI，也可以是寻呼早期指示PEI，PEI用于指示UE在目标PO上是否接收承载寻呼指示信息的PDCCH。相应地，PDCCH的监听时机可以是承载寻呼DCI的PDCCH的监听时机，也可以是承载PEI的DPCCH的监听时机。
对于空闲状态或非激活状态的终端设备，其通过在初始BWP上的公共搜索空间接收PDCCH，这些PDCCH的不同监听时机对应的QCL信息是与SSB进行关联，即不同的监听时机关联不同的SSB-index。当PDCCH承载空闲状态或非激活状态的终端设备使用的TRS、CSI-RS资源的可用资源或传输时机时，优选的方式可以包括，承载该信息的PDCCH的QCL与所指示的可用TRS、CSI-RS资源的QCL信息有关联关系，如PDCCH的监听时机对应的SSB-index与该PDCCH所指示的可用TRS、CSI-RS资源的QCL信息对应的SSB-index相同，或者具有QCL关系。
另外，可选地，承载PEI的参考信号对应的QCL信息和该PEI所指示的可用TRS、CSI-RS资源的QCL信息可以具有对应关系。
现有技术中，PEI还可以通过序列进行承载，例如SSS(Secondary Synchronization Signal，辅同步信号)、TRS、CSI-RS信号等。不同的参考信号序列表示不同的PEI的内容。
当通过PEI指示可用TRS、CSI-RS资源时，承载PEI的参考信号对应的QCL信息与该PEI所指示的可用TRS、CSI-RS资源的QCL信息可以具有对应关系。例如，承载PEI的参考信号的QCL信息对应的SSB-index与该PEI所指示的可用TRS、CSI-RS资源的QCL信息对应的SSB-index相同，或者具有QCL关系。
