Description

确定省电信号的方法及装置、通信设备和存储介质 技术领域
本公开实施例涉及无线通信领域，尤其涉及一种确定省电信号的方法及装置、通信设备和存储介质。

为了更好地描述本公开任一实施例，本公开一实施例以一个接入控制的应用场景为例进行示例性说明。
请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，终端)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G 系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网 关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，本公开实施例提供一种确定省电信号的方法，该方法应用于终端，包括：
步骤S101、发送所述终端在支持使用附加参考符号的情况下的第一辅助信息；其中，所述第一辅助信息用于确定所述终端支持的第一省电信号，所述第一省电信号用于所述终端监听寻呼消息。
终端可以向网络设备(如基站)发送第一辅助信息，该第一辅助信息可供网络设备对终端进行省电信号的配置。例如，终端发送的第一辅助信息可包括终端支持的省电信号的范围，或者支持的省电信号所在位置的取值等等。如此，网络设备则可根据第一辅助信息配置相应的省电信号。
在本公开实施例中，第一辅助信息是终端在支持使用附加参考符号的情况下，用于告知网络设备终端所支持的省电信号的辅助信息。当终端支持使用附加参考符号时，可利用附加参考符号辅助进行信道状态信息获取或者网络的时频域同步以及辅助RRM(Radio Resource Management，无线资源管理)测量等等。在利用附加参考符号进行时频域同步时，相比于SSB同步，附加参考符号的配置位置距离PO更近，因此终端可以更晚醒过来。因此，在终端支持使用附加参考符号时，与终端不支持使用附加参考符号时所支持的省电信号可能存在差异。
因此，在本公开实施例中，终端发送自身在支持使用附加参考符号的情况下所支持的省电信号的第一辅助信息，与不支持使用附加参考符号的情况加以区分，从而便于网络设备对终端的省电信号进行对应的配 置，使得终端可以配合附加参考符号监听省电信号，从而能够更加省电。
在一些实施例中，所述第一省电信号进一步用于所述终端在非激活态和/或空闲态监听所述寻呼消息。
在本公开实施例中，第一省电信号用于使终端确定在空闲态及非激活态下是否以及何时进行寻呼的监听。例如，终端检测第一省电信号，若检测到第一省电信号，则在下一个监听周期内监听寻呼消息；而如果未检测到第一省电信号，则跳过下一个监听周期，不监听寻呼消息。
又如，终端检测到省电信号，则在下N个监听周期内监听寻呼消息，若在第N+1个寻呼周期之前未检测到第一省电信号，则跳过该寻呼周期，不监听寻呼消息。
如此，终端可以基于第一省电信号选择性地监听寻呼，从而减少不必要的监听，进而达到降低功耗的目的。
在一些实施例中，所述附加参考符号用于辅助终端与网络设备进行时频域同步，所述附加参考符号包括以下至少一种：
TRS以及CSI-RS。
在本公开实施例中，终端支持的附加参考符号包括CSI-RS，主要用于获取下行链路的信道状态信息、波束管理、时频追踪、移动性管理以及速率匹配等等。
附加参考符号还可包括TRS，TRS也是一种CSI-RS，用于进行时频域的跟踪，以及补偿时偏和频偏等等。
因此，终端可以利用附加参考符号辅助进行与网络间的时频域同步。
如图3所示，本公开实施例提供一种确定省电信号的方法，该方法应用于终端，包括：
步骤S201、发送所述终端在不支持使用所述附加参考符号的情况下的第二辅助信息，所述第二辅助信息用于确定第二省电信号。
在本公开实施例中，终端也可能不支持使用上述实施例中所涉及的附加参考符号。对于不支持使用附加参考符号的情况，终端支持省电信号的能力可能也不同于支持附加参考符号时的情况。因此，终端可以向网络设备上报自身在不支持使用附加参考符号的情况下，所支持的第二省电信号的第二辅助信息。
在一实施例中，终端可以分别上报支持附加参考符号情况下的第一辅助信息以及不支持附加参考符号情况下的第二辅助信息，从而使网络设备对终端配置两种情况下对于省电信号的配置信息，便于终端在不同情况下以不同的参数监听省电信号，提升了省电信号的应用场景和范围。
在一些实施例中，发送所述第一辅助信息，包括：向网络设备发送能力上报信息，所述能力上报信息包括所述第一辅助信息；
发送所述第二辅助信息，包括：向网络设备发送能力上报信息，所述能力上报信息包括所述第二辅助信息。
在本公开实施例中，终端可以在上报自身能力时上报上述辅助信息，即利用上述能力上报信息来发送第一辅助信息和/或第二辅助信息。例如，将辅助信息携带在UE-RadioPagingInfo(终端寻呼信息)的终端能力中上报给基站。
如此，终端不需要额外的信令，利用已有的上报信息就可以将辅助信息携带并发送至基站等网络设备。
如图4所示，本公开实施例提供一种确定省电信号的方法，该方法应用于终端，包括：
步骤S301、接收网络设备根据所述第一辅助信息和/或所述第二辅助信息发送的配置信息，其中，所述配置信息包括省电信号相对于寻呼时机PO的偏移值。
这里，配置信息用于配置省电信号，终端可根据配置信息的配置， 确定以何种方式根据省电信号唤醒终端并监听寻呼消息。
例如，终端接收的省电信号的配置信息配置了省电信号的位置与PO之间的偏移值，则终端可以根据配置信息以及PO的位置确定省电信号的位置。这样，终端可根据省电信号的位置唤醒，并监听省电信号，若监听到省电信号则可以进一步接收寻呼消息。而如果配置信息在一些寻呼周期内未配置省电信号，则终端可以不唤醒，从而跳过寻呼消息的监听。如此，终端可以减少不必要的寻呼监听，从而达到降低功耗的目的。
在一些实施例中，所述配置信息由终端从网络设备的广播信令中读取，或者
所述配置信息由终端从专用于携带所述配置信息的专用信令中读取。
上述配置信息可以由基站的广播信令发送至终端，也可以由基站的专用信令发送至终端。例如，基站将上述第一配置信息和第二配置信息均携带在同一条广播信令中发送至终端，或者分别携带在不同的广播信令中依次发送至终端。又如，基站将第一配置信息携带在广播信令中发送至终端，将第二配置信息携带在专用信令中发送至终端。再如，基站将第一配置信息和第二配置信息分别携带在不同的专用信令中再依次发送至终端等等。
当然，除此之外，上述第一配置信息以及第二配置信息也可由协议约定，或者由协议约定网络设备如何发送至终端。
在一些实施例中，所述配置信息包括：
所述第一省电信号的第一配置信息和/或所述第二省电信号的第二配置信息。
在本公开实施例中，上述配置信息可以为携带在同一条消息中的，用于配置所述第一省电信号的第一配置信息和/或用于配置所述第二省电 信号的第二配置信息；也可以为携带在单独的消息中，用于单独配置所述第一省电信号的第一配置信息，和/或携带在单独的消息中，用于单独配置所述第二省电信号的第二配置信息。
在本公开实施例中，对于终端支持使用附加参考符号以及不支持使用附加参考符号的两种情况，可具有不同的辅助信息(即上述第一辅助信息和第二辅助信息)，进而可以获得不同的配置信息，即上述对第一省电信号的第一配置信息和对第二省电信号的第二配置信息。
因此，终端可以获得网络设备对应的配置信息。网络设备可以将上述第一配置信息和第二配置信息携带在同一条消息中发送至终端，也可以将第一配置信息和第二配置信息分别用单独的消息发送至终端。终端则可通过接收到的消息分别获取第一配置信息以及第二配置信息，并在不同的对于附加参考符号的使用情况，根据不同的配置信息监听对应的省电信号。
在一些实施例中，所述方法还包括：
根据所述第一配置信息，确定所述第一省电信号的位置信息；和/或
根据所述第二配置信息，确定所述第二省电信号的位置信息；
根据所述第一省电信号的位置信息和/或所述第二省电信号的位置信息，监听所述寻呼消息。
这里，根据第一配置信息和第二配置信息可以确定不同情况下省电信号的位置信息。
例如，终端接收的省电信号的配置信息配置了省电信号的位置与PO之间的偏移值，则终端可以根据配置信息以及PO的位置确定省电信号的位置。这样，终端可根据省电信号的位置唤醒，并监听省电信号，若监听到省电信号则可以进一步接收寻呼消息。而如果配置信息在一些寻呼周期内未配置省电信号，则终端可以不唤醒，从而跳过寻呼消息的监听。 如此，终端可以减少不必要的寻呼监听，从而达到降低功耗的目的。
在一些实施例中，所述根据所述第一配置信息，确定所述第一省电信号的位置信息，包括：
响应于接收到所述第一配置信息，则确定所述第一省电信号生效；
响应于所述第一省电信号生效，则根据所述第一配置信息确定所述第一省电信号的位置信息。
在本公开实施例中，终端可以在接收到第一省电信号的第一配置信息时马上应用该第一配置信息，也就是接收到第一配置信息则默认该配置信息对应的第一省电信号生效。
因此，如果终端接收到用于配置上述第一省电信号的第一配置信息，则第一省电信号生效。此时，终端则可根据第一配置信息确定第一省电信号的位置信息，进而根据第一省电信号监听寻呼消息。
当然，如果终端接收到了第二省电信号的配置信息，则第二省电信号生效，终端可根据第二省电信号监听寻呼消息。在一实施例中，终端若接收到了第一省电信号的第一配置信息，也接收到了第二省电信号的第二配置信息，由于第一省电信号是在终端支持附加参考符号时的情况下对应的省电信号，具有更好的省电性能，而此时终端支持附加参考符号，因此，终端可认为第一省电信号生效并优先根据第一省电信号进行寻呼的监听。
在一些实施例中，所述根据所述第一配置信息，确定所述第一省电信号的位置信息，包括：
响应于接收到通知所述第一省电信号生效的通知消息，则确定所述第一省电信号生效；
响应于所述第一省电信号生效，则根据所述第一配置信息确定所述第一省电信号的位置信息。
在本公开实施例中，终端如果接收到第一省电信号的第一配置信息，可以不马上根据该第一配置信息来监听省电信号，而是继续用第二省电信号的第二配置信息(即不支持附加参考符号的情况)进行监听。第一省电信号的生效则根据网络设备发送的通知消息来确定。也就是说，当终端接收到第一省电信号生效的通知消息，才确认第一省电信号生效，进而根据对应的配置信息确定第一省电信号的位置信息，并基于第一省电信号进行寻呼消息的监听。
在一些实施例中，所述方法还包括：
响应于所述第一省电信号未生效，则回落至根据所述第二配置信息对应的偏移值确定所述第二省电信号的位置信息。
在本公开实施例中，终端可能已经获取到了第一省电信号的第一配置信息和第二省电信号的第二配置信息，也可能未获取到第一配置信息(如，仅获取到了不支持附加参考符号的情况下对应的第二配置信息)。如果第一省电信号未生效，即没有接收到指示第一省电信号生效的通知消息，例如，终端当前不支持使用附加参考符号的情况，此时，终端则不能根据第一省电信号的位置信息进行监听，因此回落至第二配置信息所对应的偏移值确定省电信号的位置信息。
如图5所示，本公开实施例提供一种确定省电信号的方法，该方法应用于终端，包括：
步骤S401、接收网络设备的指示信息；
步骤S402、根据所述指示信息，向所述网络设备发送所述终端在支持使用附加参考符号的情况下的所述第一辅助信息。
终端向网络设备发送第一辅助信息可以基于网络设备的指示，例如，基站指示终端上报第一辅助信息，则终端基于终端的能力状态上报在支持使用附加参考符号的情况下对应的第一辅助信息。示例性地，网络设 备可以在指示终端支持使用附加参考符号时，也可以在其他情况下指示终端上报相应的辅助信息，例如，终端不支持使用附加参考符号时，指示终端上报支持和/或不支持使用附加参考符号的情况下分别对应的辅助信息。
在其他实施例中，终端也可以根据协议约定的规则上报上述第一辅助信息而不经过网络设备的指示。此外，终端还可基于网络设备的指示，上报第二辅助信息。即终端需要确定网络设备是否支持基于辅助信息进行配置的特性，因此基于网络设备的指示来上报辅助信息。
在一些实施例中，所述接收网络设备的指示信息，包括以下至少一种：
接收网络设备发送的广播信令，并从所述广播信令中获取所述指示信息；
接收网络设备发送的专用于携带所述指示信息的专用信令，并从所述专用信令中获取所述指示信息。
在本公开实施例中，上述指示信息可以携带在广播信令中也可以携带在专用信令中，专用信令则为专门用于携带该指示信息并发送至终端的信令。终端可以在接收到上述广播信令或者专用信令时读取其中携带的指示信息，并基于指示信息上报第一辅助信息。
在一些实施例中，响应于所述指示信息用于指示所述终端支持附加参考符号，则终端根据所述指示信息发送所述终端在支持使用附加参考符号的情况下的所述第一辅助信息。
上是指示信息可以为用于指示终端支持附加参考符号的信息，如果终端接收到该指示信息，则确定需要上报相应的第一辅助信息。也就是说，上述指示信息不需要携带明确指示终端上报第一辅助信息的字段，而是隐含了指示终端进行上报。终端根据指示信息确认自身支持附加参 考符号，则对应上报第一辅助信息。
在一些实施例中，响应于所述指示信息用于指示述终端支持附加参考符号且支持使用所述省电信号，则终端根据所述指示信息发送所述终端在支持使用附加参考符号的情况下的所述第一辅助信息。
在本公开实施例中，上述指示信息还可以用于指示终端支持使用附加参考符号同时支持使用省电信号。终端则可以及基于指示信息确定利用附加参考符号来辅助同步，同时可以利用省电信号进行寻呼的监听。
此时，终端则可上报在支持使用附加参考符号的情况下对应的第一辅助信息，而不需要获得明确的上报辅助信息的指示。也就是说，这里的指示信息隐含指示终端上报第一辅助信息。因此，终端不需要再额外接收用于指示上报第一辅助信息的其他信息。
如图6所示，本公开实施例提供一种确定省电信号的方法，所述方法应用于网络设备，包括：
步骤S501、接收终端在支持使用附加参考符号的情况下的第一辅助信息；其中，所述第一辅助信息用于确定所述终端支持的第一省电信号，所述第一省电信号用于所述终端监听寻呼消息。
在本公开实施例中，网络设备(如基站)可以接收终端发送的第一辅助信息，并根据第一辅助信息对终端进行省电信号的配置。例如，终端发送的第一辅助信息可包括终端支持的省电信号的范围，或者支持的省电信号所在位置的取值等等。如此，网络设备则可根据第一辅助信息配置相应的省电信号。
在本公开实施例中，第一辅助信息是终端在支持使用附加参考符号的情况下，用于告知网络设备终端所支持的省电信号的辅助信息。当终端支持使用附加参考符号时，可利用附加参考符号辅助进行信道状态信息获取或者网络的时频域同步以及辅助RRM测量等等。在利用附加参考 符号进行时频域同步时，相比于SSB同步，附加参考符号的配置位置距离PO更近，因此终端可以更晚醒过来。因此，在终端支持使用附加参考符号时，与终端不支持使用附加参考符号时所支持的省电信号可能存在差异。
因此，在本公开实施例中，网络设备接收终端在支持使用附加参考符号的情况下所支持的省电信号的第一辅助信息，与不支持使用附加参考符号的情况加以区分，从而便于对终端的省电信号进行对应的配置，使得终端可以配合附加参考符号监听省电信号，从而能够更加省电。
在一些实施例中，所述第一省电信号进一步用于所述终端在非激活态和/或空闲态监听寻呼消息。
在本公开实施例中，第一省电信号用于使终端确定在空闲态及非激活态下是否以及何时进行寻呼的监听。例如，终端检测第一省电信号，若检测到第一省电信号，则在下一个监听周期内监听寻呼消息；而如果未检测到第一省电信号，则跳过下一个监听周期，不监听寻呼消息。
又如，终端检测到省电信号，则在下N个监听周期内监听寻呼消息，若在第N+1个寻呼周期之前未检测到第一省电信号，则跳过该寻呼周期，不监听寻呼消息。
如此，终端可以基于第一省电信号选择性地监听寻呼，从而减少不必要的监听，进而达到降低功耗的目的。
在一些实施例中，所述附加参考符号用于终端与网络设备进行时频域同步；所述附加参考符号包括以下至少一种：
TRS；以及
CSI-RS。
在本公开实施例中，终端支持的附加参考符号包括CSI-RS，主要用于获取下行链路的信道状态信息、波束管理、时频追踪、移动性管理以 及速率匹配等等。
附加参考符号还可包括TRS，TRS也是一种CSI-RS，用于进行时频域的跟踪，以及补偿时偏和频偏等等。
因此，终端可以利用附加参考符号辅助进行与网络间的时频域同步。
在一些实施例中，所述方法还包括：
接收所述终端在不支持使用附加参考符号的情况下的第二辅助信息；其中，所述第二辅助信息用于确定第二省电信号。
在本公开实施例中，终端也可能不支持使用上述实施例中所涉及的附加参考符号。对于不支持使用附加参考符号的情况，终端支持省电信号的能力可能也不同于支持附加参考符号时的情况。因此，网络设备可以获取终端在不支持使用附加参考符号的情况下，所支持的第二省电信号的第二辅助信息。
在一实施例中，网络设备可以分别接收终端支持附加参考符号情况下的第一辅助信息以及不支持附加参考符号情况下的第二辅助信息，从而便于终端配置两种情况下对于省电信号的配置信息，进而使终端在不同情况下以不同的参数监听省电信号，提升了省电信号的应用场景和范围。
在一些实施例中，所述方法还包括：
根据所述第一辅助信息和/或所述第二辅助信息，发送配置信息，其中，所述配置信息包括省电信号相对于PO的偏移值。
这里，配置信息用于配置省电信号，网络设备基于终端提供的辅助信息向终端发送配置信息，从而便于终端根据配置信息的配置确定以何种方式根据省电信号唤醒终端并监听寻呼消息。
例如，终配置信息配置了省电信号的位置与PO之间的偏移值，则终端可以根据配置信息以及PO的位置确定省电信号的位置。这样，终端可 根据省电信号的位置唤醒，并监听省电信号，若监听到省电信号则可以进一步接收寻呼消息。而如果配置信息在一些寻呼周期内未配置省电信号，则终端可以不唤醒，从而跳过寻呼消息的监听。如此，终端可以减少不必要的寻呼监听，从而达到降低功耗的目的。
在一些实施例中，所述根据所述第一辅助信息和/或所述第二辅助信息，发送配置信息，包括：
根据所述第一辅助信息和/或所述第二辅助信息，通过广播信令发送所述配置信息；或者
根据所述第一辅助信息和/或所述第二辅助信息，通过专用于携带所述配置信息的专用信令发送所述配置信息。
上述配置信息可以由基站的广播信令发送至终端，也可以由基站的专用信令发送至终端。例如，基站将上述第一配置信息和第二配置信息均携带在同一条广播信令中发送至终端，或者分别携带在不同的广播信令中依次发送至终端。又如，基站将第一配置信息携带在广播信令中发送至终端，将第二配置信息携带在专用信令中发送至终端。再如，基站将第一配置信息和第二配置信息分别携带在不同的专用信令中再依次发送至终端等等。
当然，除此之外，上述第一配置信息以及第二配置信息也可由协议约定，或者由协议约定网络设备如何发送至终端。
在一些实施例中，所述配置信息包括：
所述第一省电信号的第一配置信息和/或所述第二省电信号的第二配置信息。
在本公开实施例中，网络设备可以向终端发送携带有用于同步配置所述第一省电信号的第一配置信息和所述第二省电信号的第二配置信息的同一条消息；或者
向终端发送携带有用于单独配置所述第一省电信号的第一配置信息的消息，和/或发送携带有用于单独配置所述第二省电信号的第二配置信息的消息。
在本公开实施例中，对于终端支持使用附加参考符号以及不支持使用附加参考符号的两种情况，可具有不同的辅助信息(即上述第一辅助信息和第二辅助信息)。因此，网络设备可以为终端分别提供不同的配置信息，即上述对第一省电信号的第一配置信息和对第二省电信号的第二配置信息。
网络设备可以将上述第一配置信息和第二配置信息携带在同一条消息中发送至终端，也可以将第一配置信息和第二配置信息分别用单独的消息发送至终端。终端则可通过接收到的消息分别获取第一配置信息以及第二配置信息，并在不同的对于附加参考符号的使用情况，根据不同的配置信息监听对应的省电信号。
在一些实施例中，所述方法还包括：
响应于所述配置信息至少包括所述第一配置信息，无需向所述终端发送通知所述第一省电信号生效的通知消息；即配置消息下发之后，则隐含该配置的生效；无需通过显式信令的方式通知生效；和/或
响应于所述配置信息至少包括所述第一配置信息，向所述终端发送通知所述第一省电信号生效的通知消息；和/或
响应于所述配置信息至少包括所述第一配置信息，向所述终端发送通知所述附加参考符号为可用状态的通知消息，其中，所述通知所述附加参考符号为可用状态的通知消息隐式指示所述第一省电信号生效。
在本公开实施例中，终端如果接收到第一省电信号的第一配置信息，可以不马上根据该第一配置信息来监听省电信号，而是继续用第二省电信号的第二配置信息(即不支持附加参考符号的情况)进行监听。网络 设备则通过发送通知消息来告知终端第一省电信号生效。此时，终端则可以根据对应的配置信息确定第一省电信号的位置信息，并基于第一省电信号进行寻呼消息的监听。
在本公开实施例中，上述通知消息可以通过显式的信息直接告知终端第一省电信号生效，例如，该通知消息的字段取值为1则生效。此外，上述通知消息也可以是用于通知终端附加参考符号为可用状态的消息，而并非直接通知终端第一省电信号生效的消息，但是该消息隐含告知了终端第一省电信号生效。因此，终端如果接收到附加参考符号为可用状态的消息，则可以确定第一省电信号生效。
在另一实施例中，网络设备向终端下发配置信息，并且其中包含有第一配置信息时，也可以隐含该第一配置信息所配置的第一省电信号生效，而不需要另外发送通知生效的消息。此时，终端接收到配置信息，就可以根据第一配置信息来进行省电信号的监听。
在一些实施例中，所述响应于所述配置信息至少包括所述第一配置信息，向所述终端发送通知所述第一省电信号生效的通知消息，包括：
响应于所述配置信息至少包括所述第一配置信息，向所述终端发送通知所述附加参考符号为可用状态的通知消息，并向所述终端发送通知所述第一省电信号生效的通知消息。
示例性地，网络设备可以在发送通知附加参考符号为可用状态的通知消息之后，向终端发送通知所述第一省电信号生效的通知消息；或者，网络设备也可以在发送通知附加参考符号为可用状态的通知消息的同时，向终端发送通知所述第一省电信号生效的通知消息，例如，将这两种通知消息携带在同一信令中发送至终端，也可以将这两种通知消息携带在不同的信令中发送至终端。
在一些实施例中，所述方法还包括：
向终端发送指示信息；其中，所述指示信息用于指示终端发送所述第一辅助信息。
在本公开实施例中，网络设备可以通过指示信息指示终端上报第一辅助信息，例如，网络设备指示终端上报第一辅助信息，则终端基于终端的能力状态上报在支持使用附加参考符号的情况下对应的第一辅助信息。示例性地，网络设备可以在指示终端支持使用附加参考符号时，也可以在其他情况下指示终端上报相应的辅助信息。
在其他实施例中，终端也可以根据协议约定的规则上报上述第一辅助信息而不经过网络设备的指示。此外，终端还可基于网络设备的指示，上报第二辅助信息。
在一些实施例中，所述向终端发送指示信息，包括以下至少一种：
向终端发送携带有所述指示信息的广播信令；以及
向终端发送携带有所述指示信息的专用信令。
在本公开实施例中，上述指示信息可以携带在广播信令中也可以携带在专用信令中，专用信令则为专门用于携带该指示信息并发送至终端的信令。终端则可以在接收到上述广播信令或者专用信令时读取其中携带的指示信息，并基于指示信息上报第一辅助信息。
在一些实施例中，响应于所述指示信息用于指示所述终端支持附加参考符号，则所述指示信息用于隐性指示所述终端可以发送所述第一辅助信息。
上是指示信息可以为用于指示终端支持附加参考符号的信息，其中并不需要包含明示终端发送第一辅助信息的内容，但是隐含了指示终端发送第一辅助信息。因此，如果终端接收到该指示信息，则可以上报相应的第一辅助信息。而终端如果未接收到该指示信息，则不进行上报。
在一些实施例中，响应于所述指示信息用于指示述终端支持附加参 考符号且支持使用所述省电信号，则所述指示信息用于隐性指示所述终端可以发送所述第一辅助信息。
上是指示信息可以为用于指示终端支持附加参考符号且用于指示终端支持使用省电信号的信息，其中并不需要包含明示终端发送第一辅助信息的内容，但是隐含了指示终端发送第一辅助信息。因此，如果终端接收到该指示信息，则可以上报相应的第一辅助信息。而终端如果未接收到该指示信息，则不进行上报。
在一些实施例中，所述方法还包括：
在所述终端释放时，将所述第一辅助信息携带在终端释放消息中发送至核心网设备；和/或
将所述第一辅助信息携带在终端能力信息通知消息发送至所述核心网设备；
其中，所述核心网设备用于将所述第一辅助信息携带在寻呼消息中发送至网络设备。
这里，可以由基站将终端上报的第一辅助信息上报至核心网，并由核心网设备确定对应终端的配置信息。基站可以在终端释放时，利用终端释放消息向核心网设备上报辅助信息，或者将辅助信息携带在终端能力信息通知消息中上报至核心网设备。
核心网设备接收到辅助信息，则可将辅助信息携带在寻呼消息中发送至对应的网络设备，该网络设备可以为RAN中的基站等设备，以便寻呼过程中对应的RAN内的基站则可基于寻呼消息中的辅助信息为待寻呼的终端配置对应的配置信息。
本公开实施例还提供如下示例：
在5G NR的省电项目中引入了省电信号，其中WUS(Wake-Up Signal，唤醒信号)即为一种低功耗的检测信号。若UE检测到WUS信 号，则意味着需要进行PDCCH的监听，若未检测到WUS，则跳过PDCCH的监听。在配置DRX的场景中，WUS信号可配置在DRX onduration(持续期间)前面，若UE未检测到WUS信号，则需要跳过整个持续期间。其中，省电信号WUS跳过持续期间的频度可以为1或者大于1的整数，也就是每1个或多个DRX周期对应1个省电信号。
在窄带通信中，可能只考虑空闲态的省电信号的应用。此时，UE对于省电信号支持的辅助信息是在连接态时通过UE能力(UE-RadioPagingInfo)上报基站，然后基站通过发往核心网设备的UE能力信息通知(UE capacity info notification)消息通知核心网设备的。其后，核心网设备会在发送往RAN的寻呼消息中添加UE对于省电信号支持的辅助信息(UE Radio Capability for Paging)，其中即包含了UE能力(UE-RadioPagingInfo)。基站利用该能力信息来配置省电信号和PO之间的offset偏移值。
在此基础上，需要考虑空闲态/非激活态的省电，则同样可以将WUS信号配置在PO之前。此时WUS信号和PO直接的gap需要满足终端和网络进行AGC以及时频域资源同步。
如图7所示，终端设备兼顾低功耗和对时延有一定要求的业务，在每个eDRX周期内，只有在设置的寻呼时间窗口(PTW)内，终端可接收下行数据，其余时间终端处于休眠状态，不接收下行数据，该模式可在下行业务时延和功耗之间取得平衡，如远程关闭煤气业务。
每个eDRX周期内，有一个寻呼时间窗口PTW(Paging Time Window)，终端在PTW内按照DRX周期(DRX周期时间短，可以认为终端不休眠、一直可达)监听寻呼信道，以便接收下行数据，其余时间终端处于休眠状态。
eDRX模式可以认为终端设备随时可达，但时延较大，时延取决于 eDRX周期配置，可以在低功耗与时延之间取得平衡。
在省电项目中，空闲态可以使用附加的TRS/CRS来辅助用户进行获取和网络的时频域同步，相比于原有的SSB同步，TRS/CRS配置可以配置距离开PO时刻更近，而原来的SSB是离开PO位置较远的，因此用户需要提前很久醒过来和SSB同步。而采用了附加的TRS/CRS之后，则可以更晚醒过来，因此可以更加省电。本公开实施例则基于空闲态TRS/CSI-RS特性引入之后对省电信号的配置方式。
在本公开实施例中，终端上报附加参考符号引入时对于省电信号支持的辅助信息。其中，附加参考符号可以包括TRS或者CSI-RS等，用于辅助终端进行同步以及辅助RRS测量等。
终端上报在非激活态和/或空闲态时使用省电信号，省电信号的起止时间配置可以是相对于某个参考点的偏移值(offset)，比如相对于寻呼时机PO的偏移值，该偏移值可以是与UE的实现密切相关的。
在一些实施例中，上述终端上报附加参考符号引入时对于省电信号支持的辅助信息可以包括：针对支持附加参考符号和不支持附加参考符号的情况分别进行上报。
示例性地，终端可利用同一条信令上报支持和不支持附加参考符号两种情况下支持省电信号的能力；也可以采用不同的上报消息分别承载上述两种不同情况下的能力进行上报。
在一实施例中，终端可将上述辅助信息携带在UE能力信息中上报给基站，例如，将辅助信息携带在UE-Radio PagingInfo中的UE能力中上报至基站。
在一些实施例中，终端上报附加参考符号引入时对于省电信号支持的辅助信息可以基于基站的指示：
基站通知终端是否支持上报附加参考符号引入时对于省电信号支持 的辅助信息；其通知方式可以是广播信令或者专用信令。
在一实施例中，若基站通知终端支持附加参考符号，则隐含指示终端支持上报附加参考符号引入时对于省电信号支持的辅助信息。
在另一实施例中，若基站通知终端支持附加参考符号且支持使用省电信号，则隐含告知终端支持上报附加参考符号引入时对于省电信号支持的辅助信息。
在本公开实施例中，UE提供给核心网设备的辅助信息可以携带在Ue释放时，基站通过发往核心网设备的释放消息通知核心网设备。
UE提供给核心网设备的辅助信息也可以携带在基站通过发往核心网设备UE能力信息通知(UE capacity info notification)消息通知核心网设备。
核心网设备则在发送往RAN的寻呼消息中携带空闲态/非激活态时使用的WUS的辅助信息，发送给RAN用于空闲态/非激活态省电信号配置。
在本公开实施例中，基站间交互消息中可以携带该终端的辅助信息；
基站之间的交互消息包括：UE上下文信息的应答消息(Retrieve UE Context Response)或者无线接入网寻呼消息(RAN Paging)。其中UE上下文信息的应答消息中是否携带该辅助信息可以基于新基站在UE上下文信息的应答消息中添加获取获取该信息的请求指示或者协议约定。
作为一种实施例，可以明确用一个标识(flag)表示，例如，flag＝1则意味着需要请求该信息。
在本公开实施例中，基站对于附加参考符号引入时配置省电信号的配置信息：
若基站可以针对未配置附加参考符号引入时配置一套省电信号，比如省电信号1，同时下发针对配置附加参考符号引入时配置的省电信号， 比如省电信号2。
示例性地，基站针对省电信号2配置的偏移值2要不大于基站为省电信号1配置的偏移值1。
在一实施例中，省电信号2为可选配置。
在本公开实施例中，省电信号2的配置包括如下至少两种方式：
方式1：基站可以将省电信号2和省电信号1配置一起通知用户，其通知方式可以是广播信令，当然也可以是专用信令；
方式2：基站可以将省电信号2的配置单独通知用户，其通知方式可以是专用信令，也可以通过广播信令分别进行通知。
在本公开实施例中，确认省电信号2生效的方式包括如下至少两种：
方式1：省电信号2可以在配置后立即生效，此时终端获取到配置后即可马上使用；
方式2：基站需要通知省电信号2生效。
作为一种实施例：基站可以在通知用户参考符号状态是可用状态(availability)的同时或者之后通知省电信号2生效。
其中，通知参考用户的可用状态可以通过广播消息，RRC消息、DCI等。
在一实施例中，通知参考用户的可用状态可以隐含省电信号2的生效。
在另一实施例中，可以用一个显示显式指示通知终端省电信号2生效。示例性地，该显示指示可以携带在通知参考用户的可用状态的同一条消息中，也可以用不同的消息携带。
在本公开实施例中，终端按照如下规则对配置的省电信号进行监听：
若终端检测到省电信号2生效；则可以使用省电信号2；否则回落到使用省电信号1。
在另一实施例中，终端也可基于基站显示指示对配置的省电信号进行监听。
