一种省电信号模式的使用方法、装置及终端 技术领域

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相 一致的装置和方法的例子。
图1是本公开一示例性实施例示出的通信***的***结构图。如图1所示，该通信***可以包括：接入网12和终端13。
接入网12中包括若干个接入网设备120。接入网设备120与核心网设备110之间通过某种接口技术互相通信，例如LTE***中的S1接口，5G NR***中的NG接口。接入网设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的***中，具备基站功能的设备的名称可能会有所不同，例如在LTE***中，称为eNodeB或者eNB；在5G NR***中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。为方便本公开实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端(英文：terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
DRX可以让UE周期性的在某些时候进入休眠期，不去监听PDCCH调度信息(或称PDCCH子帧)。而在UE需要监听PDCCH调度信息的时候，则从休眠期中唤醒(wake up)，这样就可以使UE达到省电的目的。
DRX的基本机制是为处于RRC_CONNECTED态的UE配置一个DRX周期(DRX cycle)。DRX cycle由“激活态(On Duration)”和“休眠期(Opportunity for DRX)”组成：在“激活态”的时间内，UE监听并接收PDCCH调度信息；在“休眠期”时间内，UE不接收下行信道的数据以节省功耗。从图2可以看出，在时域上，时间被划分成一个个连续的DRX周期(Cycle)。当UE在“激活态”期间收到一个调度消息时，UE会启动一个DRX非活跃态定时器(DRX-Inactivity Timer)并在该期间的每一个子帧监听PDCCH调度信息；如果DRX-inactivity Timer正在运行，那么即便原本配置的On Duration时间已经结束，UE仍然需要继续监听下行的PDCCH子帧，直到DRX Inactivity Timer的超时。
一个DRX周期等于UE的唤醒时间和休眠时间的总和，唤醒时间即为一个周期内的激活态的时长，休眠时间即为一个周期内的休眠期的时长。在通信***里，***可以根据不同的业务场景，给UE分别配置短DRX周期(short DRX cycle)，如图2所示，或者长DRX周期(long DRX cycle)，如图3所示。长DRX周期的休眠时期比短DRX周期的休眠时期长，或者说，长DRX周期的休眠时长占比比短DRX周期的休眠时长占比大。
在将省电信号和DRX进行协同工作时，尚未存在合适的解决方案。
在相关技术中的一种可能的实现方式中，在配置DRX的场景，省电信号通常配置在DRX on duration前面，若UE没有检测到省电信号，则需要跳掉整个激活态。这种方式下，相当于UE只能在进入激活时间之前使用省电监听模式，这样的话，将导致后续的非活跃态和短周期都无法开启，因此会带来较大的时延。
而本公开给出省电信号和DRX如何协同工作的一种解决方案，即在UE进入On Duration时间之后，在不同DRX定时器运行期间(长DRX周期的持续时长定时器、非活跃态定时器、短DRX周期的持续时长定时器、重传定时器)决定是否使用省电信号监听模式，以及使用哪一种省电信号监听模式的技术方案。
省电信号又称节能信号，省电信号包括唤醒信号(Wake Up Signaling，WUS)，下面以唤醒信号WUS为例对本公开做进一步详细阐述。但省电信号不限于WUS，还可以是ZC序列，还可以是下行控制信息(Downlink Control lnformation，DCI)中的预定比特位等其他可能实现方式。
图4示出了本公开一示例性实施例示出的省电信号模式的使用方法的流程图。该方法可以由图1所示的通信***中的终端来执行。该方法可以包括如下几个步骤。
步骤101，终端确定处于运行状态的DRX定时器。
DRX定时器是与DRX机制有关的定时器。
终端确定DRX定时器的类型包括：长DRX周期(long DRX cycle)的持续时长定时器(on duration timer)、非活跃态定时器(DRX-Inactivity Timer)、 短DRX周期(short DRX cycle)的持续时长定时器(on duration timer)、重传定时器中的任意一种。
步骤102，终端根据DRX定时器，确定是否使用省电信号监听模式，本实施例中以使用唤醒信号(Wake Up Signaling，WUS)监听模式为例。
终端根据DRX定时器的类型，来确定是否使用唤醒信号进行监听模式。
步骤103，终端在确定使用省电信号WUS监听模式时，根据WUS监听模式监听省电信号WUS。
终端根据不同的状态确定是否使用省电信号WUS的监听模式，以及在确定使用省电信号WUS监听模式时，使用哪一种WUS监听模式。
WUS的监听模式包括：WUS的周期以及WUS的起始时间偏移。
综上所述，本实施例提供的方法，通过根据DRX定时器来确定是否使用省电信号模式，并在使用省电信号模式时，采用该省电信号模式进行监听，能够根据不同的DRX定时器的类型来选择不同的省电信号使用方式，比如：使用高监听密度的省电信号模式、使用低监听密度的省电信号模式、在低时延要求的场景下可以不使用省电信号模式等等，从而解决省电信号与DRX如何进行协同工作的问题。

可选地，当使用不同的第一WUS监听模式和第二WUS监听模式时，第二WUS监听模式的延时小于第一WUS监听模式的延时。或，第二WUS监听模式的监听粒度高于第一WUS监听模式的监听粒度。
综上所述，本实施例提供的方法中，终端根据DRX定时器的类型确定使用何种WUS监听模式，即DRX定时器在不同的运行状态时可以采用不同的WUS监听模式，也可以采用相同的WUS监听模式。
当使用不同的WUS监听模式时，第二WUS监听模式的延时小于第一WUS监听模式的延时，使得终端在短DRX周期的情况下，减小因WUS所引入的延时对数据传输的影响。

图9示出了本公开一示例性实施例示出的一种省电信号模式的使用方法的流程图。该方法可以由图1所示的通信***中的终端来执行。该方法可以包括如下几个步骤。
步骤601，终端确定处于运行状态的DRX定时器。
DRX定时器可以是长DRX周期的持续时长定时器或短DRX周期的持续时长定时器。
在DRX定时器是长DRX周期的持续时长定时器时，执行步骤602。
在DRX定时器是短DRX周期的持续时长定时器时，执行步骤603。
步骤602，当DRX定时器为长DRX周期的持续时长定时器时，确定使用第一WUS监听模式。
步骤603，当DRX定时器为重传定时器时，确定使用第四WUS监听模式。
其中，第一WUS监听模式和第四WUS监听模式是相同的，或者，第一WUS监听模式和第四WUS监听模式是不同的，监听模式在本实施例中不做限定。
可选地，当使用不同的第一WUS监听模式和第四WUS监听模式时，第四WUS监听模式的延时小于第一WUS监听模式的延时。或，第四WUS监听模式的监听粒度高于第一WUS监听模式的监听粒度。
综上所述，本实施例提供的方法中，终端根据DRX定时器的类型确定使用何种WUS监听模式，即DRX定时器在不同的运行状态时可以采用不同的 WUS监听模式，也可以采用相同的WUS监听模式。
当使用不同的WUS监听模式时，第三WUS监听模式的延时小于第一WUS监听模式的延时，使得终端在重传定时器的情况下，减小因WUS所引入的延时对数据传输的影响。
图10示出了本公开一示例性实施例示出的一种省电信号模式的使用方法的流程图。该方法可以由图1所示的通信***中的终端来执行。该方法可以包括如下几个步骤。

在DRX定时器是短DRX周期的持续时长定时器时，执行步骤703。
步骤702，当DRX定时器为长DRX周期的持续时长定时器时，确定使用WUS监听模式。
步骤703，当DRX定时器为重传定时器时，确定不使用WUS监听模式。
综上所述，本实施例提供的方法，终端根据DRX定时器的类型确定是否使用WUS监听模式，当DRX定时器为重传定时器时，确定不使用WUS监听模式，使得终端在重传定时器的情况下，避免因WUS所引入的延时对数据传输的影响。
上述实施例还可以自由组合，本申请实施例对上述实施例的组合形式不加以限定。比如本公开提供有如下实施例。
图11示出了本公开一示例性实施例示出的一种省电信号模式的使用方法的流程图。该方法可以由图1所示的通信***中的终端来执行。该方法可以包括如下几个步骤。
步骤801，终端确定处于运行状态的DRX定时器。其中，终端的运行状态可以是以下四种状态中的任一种，
步骤802，当DRX定时器为长DRX周期的持续时长定时器时，使用第一WUS监听模式；

步骤805，当DRX定时器为重传定时器时，使用第四WUS监听模式或不使用WUS监听模式。
需要说明的一点是，DRX定时器的每种运行状态对应的WUS监听模式可以是相同或不同的。
在基于上述任一实施例的可选实施例中，省电信号的监听模式的使用方式是预配置的；或者，WUS监听模式的使用方式是预定义的。即，WUS监听模式可以通过***消息或者专用信令方式通知UE，或者，通过协议规定的方式预先定义。
在基于上述任一实施例的可选实施例中，省电信号的周期是DRX周期的1/N倍或N倍；DRX周期为长DRX周期或短DRX周期。
在基于上述任一实施例的可选实施例中，省电信号的周期是DRX持续时长定时器的1/N倍或N倍，DRX周期为长DRX周期或短DRX周期；其中，N为大于或等于1的整数。
N取值越大，则意味着监听粒度更小，为高监听活跃度；反之，N取值越小，则意味着监听粒度越大，为低监听活跃度。
在基于上述任一实施例的可选实施例中，WUS的周期是以绝对时间的时长配置的，也即可以将WUS的周期配置为固定的时间长度，例如可以是10毫秒或4毫秒。
在基于上述任一实施例的可选实施例中，WUS监听模式包括WUS的起始时间偏移；WUS的起始时间偏移是以DRX周期的激活态(on duration)为参考配置的偏移值。
下述为本公开的装置实施例，可以用于执行本公开方法实施例。对于本公开装置实施例中未披露的细节，请参照本公开方法实施例。
