Description

终端状态切换方法及装置、通信设备及存储介质 技术领域
本公开涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种终端状态切换方法及装置、通信设备及存储介质。
背景技术
扩展现实(eXtended Reality，XR)业务是移动通信系统所要支持的业务类型中的一种，XR包业务包括：增强现实(Augment Reality，AR)、虚拟现实(Virtual Reality，VR)或云游戏(Cloud gaming)等云业务等等。
XR业务的典型特点是：固定帧率的业务，即业务到达用户设备(User Equipment，UE)有固定周期，但在该固定周期之上会有额外的时延抖动(Jitter)，导致实际数据业务到达UE会有所提前或者推迟。
另外终端(或称UE)也具有不同的状态，不同状态下的UE响应业务的速率不同。
发明内容
本公开实施例提供一种终端状态切换方法及装置、通信设备及存储介质。
本公开实施例第一方面提供一种终端状态切换方法，其中，由终端执行，所述方法包括：
检测到所述终端结束第一状态，监听低功耗唤醒信号LP-WUS；
其中，所述LP-WUS，用于唤醒所述终端进入监听物理下行控制信道PDCCH和/或物理下行共享信道PDSCH的第二状态。
本公开实施例第二方面提供一种终端状态控制方法，其中，由基站执行，所述方法包括：
终端结束第一状态，确定是否有所述终端的业务数据达到；
检测到有所述终端的业务数据达到，发送低功耗唤醒信号LP-WUS；
其中，所述LP-WUS，用于唤醒所述终端进入监听物理下行控制信道PDCCH和/或物理下行共享信道PDSCH的第二状态；
所述业务数据，用于在所述终端进入所述第二状态之后发送给所述终端。
本公开实施例第三方面提供一种终端状态切换装置，其中，所述装置包括：
监听模块，被配置为检测到所述终端结束第一状态，监听低功耗唤醒信号LP-WUS；
其中，所述LP-WUS，用于唤醒所述终端进入监听物理下行控制信道PDCCH和/或物理下行共享信道PDSCH的第二状态。
本公开实施例第四方面提供一种终端状态控制装置，其中，由基站执行，所述装置包括：
确定模块，被配置为终端结束第一状态，确定是否有所述终端的业务数据达到；
发送模块，被配置为检测到有所述终端的业务数据达到，发送低功耗唤醒信号LP-WUS；
其中，所述LP-WUS，用于唤醒所述终端进入监听物理下行控制信道PDCCH和/或物理下行共享信道PDSCH的第二状态；
所述业务数据，用于在所述终端进入所述第二状态之后发送给所述终端。
本公开实施例第五方面提供一种通信设备，包括处理器、收发器、存储器及存储在存储器上并能够有所述处理器运行的可执行程序，其中，所述处理器运行所述可执行程序时执行如前述第一方面或第二方面提供的终端状态切换方法。
本公开实施例第十方面提供一种计算机存储介质，所述计算机存储介质存储有可执行程序；所述可执行程序被处理器执行后，能够实现前述的第一方面或第二方面提供的终端状态切换方法。
本公开实施例提供的技术方案，在本公开实施例中，若检测到终端结束第一状态，并不是直接进入到监听PDCCH和/或PDSCH的高功耗状态，而是进入到监听LP-WUS的状态。如此，若网络设备侧无需唤醒终端监听PDCCH和/或PDSCH，若终端会监听不到LP-WUS，则终端也不会进入到监听PDCCH和/或PDSCH的状态，从而节省了终端功耗，延长了终端的待机时长。且由于终端结束第一状态之后，进入到LP-WUS状态，相对于第一状态，终端的休眠程度是更浅的，如此，网络设备与终端之间进行信息交互时，终端的处理器(例如，CPU或者MCU)等是可以及时唤醒，并与网络设备进行通信的，从而也兼顾了通信效率。
应当理解的是，以上的一般描述和后文的细节描述仅是示例性和解释性的，并不能限制本公开实施例。

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UE 11以及若干个接入设备12。
其中，UE 11可以是指向用户提供语音和/或数据连通性的设备。UE 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，UE 11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE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UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE 11也可以是无人飞行器的设备。或者，UE 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通信设备。或者，UE 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。
接入设备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)。或者，MTC系统。
其中，接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者，接入设备12也可 以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备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，本公开实施例对接入设备12的具体实现方式不加以限定。
接入设备12和UE 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。
R17终端节能项目引入了跳过PDCCH监听的特性。基站可以在下行控制信息(Downlink Control Information，DCI)中指示UE在接下来的X个时隙内跳过PDCCH的监听。这这段时间内，终端不用监听PDCCH，可以处于深度睡眠状态，因而可以节能。X的若干可选值由高层信令配置。示例性地，该X的取值可为2。
终端可配置C-DRX。终端可以被配置周期的在开启状态和关闭状态(on-off)之间切换的时域pattern，每当达到开启时段时(on duration)就开启PDCCH监听，当PDCCH监听结束后或者关闭时段(off duration)到来后即可进入睡眠状态，因而可以节能。
低功耗唤醒信号(Low power wake up signal,LP-WUS)，终端主机可以处于睡眠状态，并开启低功耗接收机来专门接收基站发送的WUS信号，以此确定是否需要开启主机。由于低功耗接收机的功率很小，故可以达到终端节能的效果。
基站为终端配置了PDCCH skipping。基站在传输完当前无线帧(frame)的数据时，可以通过DCI指示终端在接下来X个时隙内执行跳过PDCCH监听。等X个时隙(时隙，仅仅是X的时间单元的一种，具体实现时还可以是符号或者微时隙等)结束后，终端将醒来继续做PDCCH监听。
但是由于XR业务传输时延抖动的原因，以及X的候选值受限的原因，UE在醒来后，可能要等到一段时间，才能收到下一个无线帧(frame)的数据。在等待的这段时间内，终端一直在进行不必要的PDCCH盲检，因而浪费了能耗。
基站为终端配置了C-DRX的传输方式，当UE在启动时段达到时将醒来监听PDCCH，但此时XR业务还未达到。UE在醒来后，可能要等到一段时间，才能收到下一个无线帧的数据。在等待的这段时间内，终端一直在进行不必要的PDCCH盲检，因而浪费了能耗。
有鉴于此，如图2所示，本公开实施例提供一种终端状态切换方法，其中，由终端执行，所述方法包括：
S1110：检测到所述终端结束第一状态，监听LP-WUS；
其中，所述LP-WUS，用于唤醒所述终端进入监听物理下行控制信道PDCCH和/或物理下行共享信道PDSCH的第二状态。
该终端可为各种类型的终端。示例性地，该终端可具有两个接收机，一个接收机可以接收PDCCH 传输和/或PDSCH传输，另一个接收机可接收LP-WUS。接收LP-WUS的接收机的功耗，可低于接收PDCCH传输和/或PDSCH传输的功耗。
示例性地，接收机可接收LP-WUS可接收物理层信号，但是可能不具有高层信息处理能力(例如，解码能力)。而接收PDCCH传输和/或PDSCH传输的接收机，具有高层信息处理能力，可以接收高层信息，并进行信息解码。
又示例性地，该终端包括但不限于XR终端。
对于XR终端，能耗是一个重要指标。XR终端可以提供XR业务。
在一个实施例中，所述第一状态包括以下至少之一：
跳过PDCCH监听的状态；
连接态-非连续监听C-DRX的关闭状态。
跳过PDCCH监听的状态为：终端不监听PDCCH的状态，如此，终端就不会因监听PDCCH产生功耗。C-DRX的关闭状态为：终端处于C-DRX的关闭时期(off duration)，终端同样不监听PDCCH和/或PDSCH，因此，终端就不会因监听PDCCH和/或PDSCH产生功耗。
也可以认为第一状态是低功耗的休眠态。
若终端结束第一状态，可以直接进入到监听PDCCH和/或PDSCH的状态，而监听PDCCH和/或PDSCH的状态是一种比第一状态的终端功耗更高的状态。
此处的监听PDCCH和/或PDSCH的状态即为所述第二状态。在一些实施例中，该第二状态可以认为是激活状态。总之，第二状态的终端功耗大于第一状态的终端功耗。
示例性地，若终端处于监听PDCCH和/或PDSCH的状态下，终端可以快速响应网络设备的指示，及时进行各上行传输的发送和/或下行传输的接收。LP-WUS是一种终端仅需极低功耗就能够监听的信号，在本公开实施例中，若终端处于LP-WUS的状态比终端处于监听PDCCH和/或PDSCH的状态的终端功耗低。
示例性地，终端监听LP-WUS的终端功耗可低于所述终端处于监听PDCCH和/或PDSCH的第二状态的功耗。
在本公开实施例中，若检测到终端结束第一状态，并不是直接进入到监听PDCCH和/或PDSCH的高功耗状态，而是进入到监听LP-WUS的状态。如此，若网络设备侧无需唤醒终端监听PDCCH和/或PDSCH，若终端会监听不到LP-WUS，则终端也不会进入到监听PDCCH和/或PDSCH的状态，从而节省了终端功耗，延长了终端的待机时长。且由于终端结束第一状态之后，进入到LP-WUS状态，相对于第一状态，终端的休眠程度是更浅的，如此，网络设备与终端之间进行信息交互时，终端的处理器(例如，CPU或者MCU)等是可以及时唤醒，并与网络设备进行通信的，从而也兼顾了通信效率。
如图3A所示，本公开实施例提供一种终端状态切换方法，其中，由终端执行，所述方法包括：
S1121：终端结束跳过PDCCH监听的状态，监听LP-WUS。
网络设备(例如，基站)可以为终端配置跳过PDCCH监听的状态，这个特定状态是前述第一 状态的一种。
示例性地，网络设备可以通过基站的高层信令给终端配置跳过PDCCH监听的状态。该高层信令包括但不限于：MAC层信令和/或RRC信令。
又示例性地，网络设备可以通过DCI向终端指示具体的跳过PDCCH监听的时段。若当前DCI指示的跳过PDCCH监听的时段，则认为终端结束跳过PDCCH监听的状态。
在一些实施例中，检测到所述终端结束第一状态，监听低功耗唤醒信号LP-WUS，包括：
检测到所述终端结束所述第一状态，进入第三状态；
在所述第三状态下，监听所述LP-WUS。
在本公开实施例中，第三状态可为终端能够监听LP-WUS的休眠状态。该休眠状态的休眠程度较浅，因此，终端处于监听LP-WUS的状态下可以快速的被唤醒，以进行下行接收和/或下行发送。
示例性地，所述第三状态可为：微休眠(micro sleep)状态或轻休眠(light sleep)状态。
在第三状态下，终端会监听LP-WUS。
如图3B所示，本公开实施例提供一种终端状态切换方法，其中，由终端执行，所述方法包括：
S1122：终端结束连接态-非连续C-DRX的关闭状态，监听LP-WUS。
若终端配置有处于连接态下的非连续接收，即终端配置有C-DRX，则终端会按照DRX的周期，周期性在关闭(off)状态和开启(on)状态之间切换。例如，终端的一个DRX周期内包括：一个开启时段和一个关闭时段。在开启时段内终端处于开启状态。在关闭时段内终端处于关闭状态。
若终端配置有C-DRX，则在C-DRX的关闭(off)状态时，终端不用监听PDCCH和/或PDSCH，且在C-DRX的启动(on)状态时，终端需要监听PDCCH和/或PDSCH。
若终端即将退出(即结束)C-DRX的off状态，即意味着终端需要进入到高功耗的开启状态，即此时可认为终端即将结束第一状态。通常情况下，若终端进入到开启状态，终端的功耗是高于监听LP-WUS的状态，且在开启状态下终端不监听LP-WUS。
在一些实施例中，检测到所述终端结束第一状态，监听低功耗唤醒信号LP-WUS，包括：
检测到所述终端结束所述第一状态，进入第三状态；
在所述第三状态下，监听所述LP-WUS。
在本公开实施例中，第三状态可为终端能够监听LP-WUS的休眠状态。该休眠状态的休眠程度较浅，因此，终端处于监听LP-WUS的状态下可以快速的被唤醒，以进行下行接收和/或下行发送。
示例性地，所述第三状态可为：微休眠(micro sleep)状态或轻休眠(light sleep)状态。
在第三状态下，终端会监听LP-WUS。
如图4所示，本公开实施例提供一种终端状态切换方法，其中，由终端执行，所述方法包括：
S1131：终端结束跳过PDCCH监听的状态，进入第三状态；
S1132：在所述第三状态下，监听LP-WUS；
S1133：在所述第三状态下未监听到所述LP-WUS的持续时长达到预定时长，进入到第四状态；
S1134：在所述第四状态下，监听所述LP-WUS。
针对终端原本的第一状态为跳过PDCCH监听的状态，终端在进入第三状态之后，且在第三状态下未监听到LP-WUS的持续时长达到时长阈值，则说明终端在第三状态下持续未监听到基站等网络设备需要唤醒终端的LP-WUS，此时，终端可以进入到更深程度的睡眠，但是为了能够被唤醒，还是会继续监听LP-WUS。
示例性地，在终端的第一状态为跳过PDCCH的状态的场景下，前述第三状态可为微休眠状态，此时的第四状态可为轻休眠状态或者深度休眠状态。如此，终端从第三状态向第四状态的进一步切换，可以进一步节省终端的功耗。
所述时长阈值可为：预先配置的时长值，或者协议约定的时长值。
示例性地，所述时长阈值可为配置在跳过PDCCH监听的配置内的时长值。
示例性地，终端根据跳过PDCCH监听的配置，确定出PDCCH跳过时段超期，就可确定所述终端结束所述第一状态。
终端的第一状态为C-DRX关闭状态，所述检测到所述终端结束第一状态，包括以下至少之一：
检测到所述终端在预定时长之后结束C-DRX关闭时段；
检测到所述终端的C-DRX关闭时段结束。
例如，在当前时刻检测到终端结束C-DRX的关闭时段的结束时刻缩小到等于预定时长，则认为检测到终端即将结束第一状态。
又例如，在当前时刻检测到终端结束C-DRX的关闭时段。
总之，上述两种方式都可认为是终端要结束第一状态的情况。
在一些实施例中，所述方法还包括：
在所述第三状态下未监听到所述LP-WUS的状况持续到进入C-DRX的关闭时段，退出所述LP-WUS的监听。
例如，此处的第三状态可为任意一种休眠状态，例如，微休眠状态或者轻休眠状态。终端在休眠状态下监听LP-WUS，但是一直未监听到LP-WUS，说明网络设备没有业务数据达到或者下行指令需要发送给终端从而唤醒终端。且这种未监听到LP-WUS的状态持续到再次进入到C-DRX的关闭时段，则终端退出所述LP-WUS的监听。
在一些实施例中，所述在所述第三状态下未监听到所述LP-WUS的状况持续到进入C-DRX的关闭时段，退出所述LP-WUS的监听，包括：
在所述第三状态下未监听到所述LP-WUS的状况持续到进入C-DRX的关闭时段，进入所述C-DRX的关闭状态。
例如，在所述第三状态下未监听到所述LP-WUS的状况持续到进入C-DRX的关闭时段，终端进入到的是进入所述C-DRX的关闭时段对应的C-DRX的关闭状态。在C-DRX的关闭状态下，终端不监听PDCCH和/或PDSCH，从而至少节省了监听PDCCH和/或PDSCH的功耗。
如图5所示，本公开实施例提供一种终端状态切换方法，其中，由终端执行，所述方法包括：
S1110：检测到所述终端结束第一状态，监听LP-WUS；
S1220：监听到所述LP-WUS，进入所述第二状态。
若终端在接收第一状态并进入到LP-WUS的监听状态之后，若成功监听到所述LP-WUS，则进入到第二状态。
在第二状态下，终端会监控PDCCH和/或PDSCH，从而使得终端可以监听到网络设备发送的下行信令和/或下行数据。
如图6所示，本公开实施例提供一种终端状态控制方法，其中，由基站执行，所述方法包括：
S2110：终端结束第一状态，确定是否有所述终端的业务数据达到；
S2120：检测到有所述终端的业务数据达到，发送LP-WUS；
其中，所述LP-WUS，用于唤醒所述终端进入监听物理下行控制信道PDCCH和/或物理下行共享信道PDSCH的第二状态；
所述业务数据，用于在所述终端进入所述第二状态之后发送给所述终端。
该终端可为各种类型的终端，包括但不必限于XR终端。
若终端结束第一状态之后，检测终端是否有业务数据达到，如果有业务数据达到，说明基站需要和终端通信，因此，基站会监听是否有业务数据达到，若检测有终端的业务数据达到，相当于有业务数据需要发送给终端。
若检测到有业务数据需要发送给终端，则发送LP-WUS先唤醒终端。或者说，基站监控到有业务数据达到，先发送LP-WUS，从使得终端进入到监听下行信道的状态，该下行状态包括但不限于：监听PDCCH和/或PDSCH的第二状态
示例性地，基站在监听到有终端的业务数据达到时，通过PDCCH调度PDSCH，如此终端根据PDCCH上监听达到的调度信息，到对应的PDSCH上监听业务数据。
又示例性地，基站有监听到终端的业务数据达到，直接通过免授权调度PDSCH发送业务数据。
在一些实施例中，所述确定结束第一状态，包括：
根据所述终端跳过PDCCH监听的高层配置和/或物理层指示，确定结束所述终端跳过PDCCH监听的状态。所述高层配置可包括：RRC信令和/或MAC CE携带的配置信息。所述物理层指示可至少包括：DCI。
基站在正常调度数据的最后一次调度中，通过下行控制信息(Downlink Control Information，DCI)指示跳过PDCCH的状态，而且会指示跳过持续(duration)X个时隙。
假设基站在时隙#n指示了跳过PDCCH监听的状态以及跳过持续(duration)X＝20.那么基站可以判断在时隙(#n+20)，终端就会结束第一状态。
当终端从跳出PDCCH监听的状态退出时，进入LP-WUS监听状态，而不是直接进入正常监听PDCCH的状态。
在LP-WUS监听状态下，UE使用低功耗接收机来接收LP WUS信号，UE的主机处于微睡眠(Micro sleep)的状态。
当基站有业务达到时，将使用LP WUS信号唤醒终端。终端收到LP WUS信号之后，从Micro sleep 状态即刻转换为正常监听PDCCH的状态，进行正常的PDCCH/PDSCH的接收。在一些实施例中，所述确定结束第一状态，包括：
根据所述终端的DRX配置，确定所述终端结束C-DRX的关闭时段。
该DRX配置可为基站发送终端的。终端DRX配置，可以确定出何时进入到C-DRX的关闭时段和/或何时进入到C-DRX的开启时段。
因此，基站可以根据DRX配置，确定终端结束C-DRX的关闭时段。
在一些实施例中，所述根据所述终端的DRX配置确定所述终端结束连接态-非连续监听C-DRX的关闭时段，包括以下至少之一：
根据所述终端的连接态-非连接接收DRX配置，确定所述终端结束所述C-DRX的关闭时段态；
根据所述终端的连接态-非连接接收DRX配置，确定所述终端在预定时长之后结束所述C-DRX的关闭时段。
若终端确定在预定时长之后结束C-DRX的关闭时段，因此相当于终端可以提前进入到监听LP-WUS的状态。
当终端从C-DRX的关闭状态跳出时，将进入LP-WUS监听状态，而不是像相关协议一样直接进入开启状态。在LP-WUS监听状态下，UE使用低功耗接收机来接收LP WUS信号，UE的主机处于Micro sleep的状态。
当基站有业务达到时，将使用LP WUS信号唤醒终端。终端收到LP WUS信号之后，从微睡眠(Micro sleep)状态即刻转换为正常监听PDCCH的状态，进行正常的PDCCH/PDSCH的接收。
在开启时段(on duration)内，在收到LP WUS信号之前，UE将保持微睡眠(Micro sleep)监听LP WUS的状态。
上述方案能够减少不必要的PDCCH盲检，因而能够节能终端能耗。同时，使用LP WUS唤醒处于Micro sleep状态的终端，终端可以立刻唤醒，对数据传输时延的影响也较小，能够保证数据传输时延性能。
针对配置C-DRX，该方案还有另一种等效形式：
在开启时段(on duration)开始时刻的T时长之前，UE切换为微睡眠(micro sleep)状态。在该状态下，UE可以接收LP WUS信号。当基站有业务达到时，将使用LP WUS信号唤醒终端。终端收到LP WUS信号之后，从Micro sleep状态即刻转换为正常监听PDCCH的状态，进行正常的PDCCH/PDSCH的接收。
在T时长和开启时段(on duration)内，在收到LP WUS信号之前，UE将保持微睡眠(Micro sleep)监听LP WUS的状态。
