Description

物理下行控制信道的检测方法、装置及终端 技术领域
本申请涉及通信领域，特别涉及一种物理下行控制信道的检测方法、装置、设备及系统。
背景技术
出于终端节电的考虑，长期演进(Long-Term Evolution，LTE)中引入了非连续接收(Discontinuous Reception，DRX)。DRX的基本机制是为处于无线资源控制(Radio Resource Control，RRC)连接态的用户设备(User Equipment，UE)配置一个DRX周期。每个DRX周期由“On Duration”和“Opportunity for DRX”组成。在“On Duration”时间(简称：激活期)内，UE监听并接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)；在“Opportunity for DRX”时间(简称：休眠期)内，UE不接收PDCCH以减少功耗。
相关技术中，引入了节能信号。如果基站判断需要在“On Duration”时间内调度UE，则向UE发送第一节能信号，使得终端在DRX的On Duration时间内进行PDCCH检测；如果基站判断不需要在On Duration时间内调度UE，则向UE发送第二节能信号，使得终端在DRX的On Duration时间内不进行PDCCH检测。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在本文提及的“模块”通常是指存储在存储器中的能够实现某些功能的程序或指令；在本文中提及的“单元”通常是指按照逻辑划分的功能性结构，该“单元”可以由纯硬件实现，或者，软硬件的结合实现。
在本文中提及的“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。
图1示出了本申请一个示意性实施例中提供的通信系统的框图。该通信系统可以是5G NR系统。该通信系统包括：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系统中的S1接口，5G NR系统中的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系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR系统中，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机制
DRX可以让终端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)。而在终端需要监听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态的终端配置一个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，终端监听并接收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)。当终端在“激活态”期间收到一个调度消息时，终端会启动一个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定时器正在运行，那么即便原本配置的On Duration时间已经结束，终端仍然需要继续监听下行的PDCCH子帧，直到DRX Inactivity Timer定时器的超时。另 外，寻呼消息的传输也是一种RRC idle状态的DRX机制，此时DRX周期为寻呼消息的周期。
一个DRX周期等于终端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。在通信系统里，系统可以根据不同的业务场景，给终端分别配置短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。
但接入网虽然给终端配置了DRX机制，终端在周期性出现的on duration仅是机会性地得到调度，甚至在终端业务负荷很低的情况下，终端仅仅有少数的DRX周期内会得到调度；对于采用DRX机制的寻呼消息而言，终端接收到寻呼消息的时机更少。因此，终端在配置了DRX机制后，仍然存在多数on duration内的PDCCH检测并没有检测到数据调度，这就存在更进一步的优化空间。
相关技术中引入了节能信号(也称省电信号)。如果接入网设备判断需要在“On Duration”时间内调度UE，则向UE发送第一节能信号，使得终端在DRX的On Duration时间内进行PDCCH检测；如果接入网设备判断不需要在On Duration时间内调度UE，则向UE发送第二节能信号，使得终端在DRX的On Duration时间内不进行PDCCH检测。
采用节能信号指示方式可以有效实现终端的省电。然而，该机制也存在一些特殊情况需要考虑，如节能信号存在一定的漏检概率，当接入网发送了节能信号但终端未收到节能信号时，终端的行为需要进一步明确。为此，本申请提供有如下实施例。
图4示出了本申请一个示例性实施例提供的PDCCH的检测方法的流程图。该方法可以由图1中的终端来执行。该方法包括：
步骤402，终端检测节能信号，该节能信号用于指示是否唤醒终端在DRX的激活期时间内进行PDCCH的检测；
步骤404，终端在未检测到节能信号时，在DRX的激活期时间内进行PDCCH的检测。
综上所述，本实施例提供的方法，由于终端在接收过程中存在一定的漏检概率，当终端在未检测到节能信号时，在DRX的激活期时间内进行PDCCH的检测，能够使得即便发生了漏检情况，也能避免终端不检测PDCCH，而导致基站不能有效地对终端进行调度的风险。
图5示出了本申请另一个示例性实施例提供的PDCCH的检测方法的流程图。本实施例是基于图4的可选实施例，该方法可以由图1中的终端来执行。该方法包括：
步骤401，终端启动节能模式；
接入网设备向终端发送信令，该信令用于控制终端启动节能模式。该信令可以是无线资源控制(Radio Resource Control，RRC)、媒体接入控制控制信元(Medium Access Control Control Element，MAC CE)。
终端接收该信令，根据该信令启动节能模式。
步骤402，终端检测节能信号，该节能信号用于指示是否唤醒终端在DRX的激活期时间内进行PDCCH的检测；
节能信号包括第一节能信号和第二节能信号。第一节能信号用于指示唤醒终端在DRX的on duration时间内进行PDCCH的检测，第二节能信号用于指示不唤醒终端在DRX的on duration时间内进行PDCCH的检测。
可选地，节能信号是一种低功耗的检测信号。
可选地，节能信号是ZC(Zadoff-chu)序列。第一节能信号是第一ZC序列，第二节能信号是第二ZC序列。此时，终端检测节能信号的方式包括：终端检测节能信号的能量是否超过与ZC序列对应的门限值；若超过门限值，则认为检测到节能信号；若未超过门限值， 则认为未检测到节能信号。
可选地，节能信号是PDCCH。第一节能信号是下行控制信息(Downlink Controllnformation,DCI)中的预定比特位取值为1，第二节能信号是DCI中的预定比特位取值为0。此时，终端检测节能信号的方式包括：
终端检测携带有DCI的PDCCH的CRC是否成功；若CRC成功，则认为检测到节能信号；若CRC失败，则认为未检测到节能信号。
可选地，终端根据节能信号的配置信息启动节能模式。在节能模式开启后，终端在配置信息所配置的时频资源位置上检测节能信号(或者，监听节能信号)。可选地，该时频资源位置是周期性出现的资源位置，每个时频资源位置位于对应的DRX的on duration时间之前。
节能信号的配置信息包括：节能信号对应的时频资源位置、序列设定(采用ZC序列作为节能信号)、PDCCH加扰的无线网络临时指示(Radio-Network Temporary Identifier，RNTI)(采用PDCCH作为节能信号)中的至少一种。该配置信息可以是通信协议预定义的，也可以是预先配置给终端，或者由网络通过高层信令发送给终端。
步骤403，当检测到节能信号时，根据节能信号的指示进行PDCCH的检测。
当节能信号是第一节能信号时，终端在DRX的下一个on duration时间内唤醒，并在on duration时间内进行PDCCH的检测。也即，第一节能信号用于指示在on duration时间内进行PDCCH的检测。
当节能信号是第二节能信号时，终端在DRX的下一个on duration时间内不唤醒，忽略在on duration时间内进行PDCCH的检测。也即，第二节能信号用于指示在on duration时间内忽略进行PDCCH的检测。
步骤404，终端在未检测到节能信号时，在DRX的激活期时间内进行PDCCH的检测。
接入网设备会在配置的时频资源位置向终端发送节能信号，但当终端出现漏检情况时，终端在该时频资源位置上未检测到节能信号。若终端未检测到节能信号，则在DRX的on duration时间内进行PDCCH的检测。
其中，终端未能检测到节能信号的原因包括：终端在接收节能信号时突然面临信道深衰，导致节能信号的漏检；或者，面临来自邻小区的突发性强干扰，导致节能信号的漏检。
上述“激活期时间”也称“持续时长期间”，是指DRX的激活期定时器(On Duration Timer)的运行期间。
综上所述，本实施例提供的方法，由于终端在接收过程中存在一定的漏检概率，当终端在未检测到节能信号时，在DRX的激活期时间内进行PDCCH的检测，能够使得即便发生了漏检情况，也能避免终端不检测PDCCH，而导致基站不能有效地对终端进行调度的风险。
在节能信号和DRX协同工作时，还有可能出现另外一种异常接收情况：终端在节能信号的检测结果指示唤醒终端在DRX的激活期时间内进行PDCCH的检测，但终端在DRX的on duration时间内未能检测到PDCCH。
导致终端在DRX的on duration时间内未能检测到PDCCH的原因，可能是如下两个原因：
一、接入网设备实际上向终端发送了PDCCH调度，但终端由于信道深衰或者周边信号的干扰等原因未检测到该PDCCH调度。
二、接入网设备期望向终端进行数据调度，但由于其他终端的高优先级的数据传输推迟了所述终端的数据调度，导致接入网设备在所述终端的DRX on-duration期间未来得及调度。
针对上述原因一，本申请实施例还提供有如下实施例。
图6示出了本申请一个示意性实施例提供的PDCCH的检测方法的流程图。该方法可以 由图1中的终端来执行。该方法包括：
步骤601，终端检测节能信号，节能信号用于指示是否唤醒终端在DRX的激活期(on duration)时间内进行PDCCH的检测；
当节能信号的检测结果指示唤醒终端在DRX的on duration时间内进行PDCCH的检测时，进入步骤602；
当节能信号的检测结果指示不唤醒终端在DRX的on duration时间内进行PDCCH的检测时，忽略进行PDCCH的检测；
步骤602，终端在节能信号的检测结果指示唤醒终端在DRX的on duration时间内进行PDCCH的检测时，在DRX的激活期时间内进行PDCCH的检测；
步骤6031，当终端在DRX的激活期时间内未监测到PDCCH时，进入DRX。
终端在DRX的激活期定时器(DRX-on duration timer)超时时，进入DRX，期待接入网设备在后续的DRX激活期时间内向终端发起新的调度。
综上所述，本实施例提供的方法，通过在未检测到PDCCH时进入DRX，终端有可能在后续的DRX激活期时间内收到接入网设备的调度。虽然该种方式导致将终端的传输延迟到下一个DRX周期，但一定程度上减少了终端继续检测PDCCH的功耗，有利于终端的节电。
针对上述原因二，本申请实施例还提供有如下实施例。
图7示出了本申请一个示意性实施例提供的PDCCH的检测方法的流程图。该方法可以由图1中的终端来执行。该方法包括：
步骤601，终端检测节能信号，节能信号用于指示是否唤醒终端在非连续接收DRX的激活期时间内进行PDCCH的检测；
当节能信号的检测结果指示唤醒终端在DRX的on duration时间内进行PDCCH的检测时，进入步骤602；
当节能信号的检测结果指示不唤醒终端在DRX的on duration时间内进行PDCCH的检测时，忽略进行PDCCH的检测；
步骤602，终端在节能信号的检测结果指示唤醒终端在DRX的on duration时间内进行PDCCH的检测时，在DRX的激活期(on duration)时间内进行PDCCH的检测；
步骤6032，当终端在DRX的激活期时间内未监测到PDCCH时，在DRX的激活期定时器超时时启动目标定时器，并在目标定时器超时前进行PDCCH的检测。
可选地，目标定时器是：DRX的不活跃态定时器(DRX-inactivityTimer)，或，第一定时器。该第一定时器是不同于不活跃态定时器的新增定时器。
在一个实施例中，在DRX的激活期定时器(DRX-on duration Timer)超时时启动DRX的不活跃态定时器，并在DRX的不活跃态定时器超时前进行PDCCH的检测。
在一个实施例中，在DRX的激活期定时器超时时启动第一定时器，并在第一定时器超时前进行PDCCH的检测，第一定时器是不同于DRX的不活跃态定时器的定时器。
综上所述，本实施例提供的方法，通过在终端的DRX-on duration Timer超时后，启动目标定时器来继续检测PDCCH，相当于延长了本次PDCCH的检测时长。若接入网设备在传输完毕高优先级的其它终端的数据后，向终端发送了数据调度，则终端能够及时地查收到该数据调度，使得终端能够尽可能及时接收到PDCCH调度。
在基于图7的可选实施例中，目标定时器采用第一定时器。在步骤702中，终端在DRX的激活期时间内，采用第一PDCCH搜索空间进行PDCCH的检测；在步骤703中，在第一定时器超时前，终端采用第二PDCCH搜索空间进行PDCCH的检测，第二PDCCH搜索空间不同于第一PDCCH搜索空间。
可选地，第二PDCCH搜索空间由接入网事先配置。也即步骤703之前，终端接收接入网设备的配置信令，该配置信令用于配置第二PDCCH搜索空间。其中，配置信令包括RRC或MAC CE。
需要说明的是，针对图6和图7所示的实施例，节能信号的实现方式包括三种可能的情形：
1、节能信号包括第一节能信号和第二节能信号，第一节能信号用于指示唤醒终端在DRX的On duration期间内进行PDCCH检测；第二节能信号用于指示唤醒终端在DRX的On duration期间内不进行PDCCH检测。
在该实现方式下，终端对节能信号的检测结果为“第一节能信号”时，用于指示唤醒终端在DRX的on duration时间内进行PDCCH的检测；终端对节能信号的检测结果为“第二节能信号”时，用于指示不唤醒终端在DRX的on duration时间内进行PDCCH的检测。
2、节能信号为一个，当该节能信号被接入网设备发送时用于指示唤醒终端在DRX的On duration期间内进行PDCCH检测；当该节能信号未被接入网设备发送时用于指示不唤醒终端在DRX的On duration期间内进行PDCCH检测。
在该实现方式下，终端对节能信号的检测结果为“检测到节能信号”时，用于指示唤醒终端在DRX的on duration时间内进行PDCCH的检测；终端对节能信号的检测结果为“未检测到节能信号”时，用于指示不唤醒终端在DRX的on duration时间内进行PDCCH的检测。
3、节能信号为一个，当该节能信号被接入网设备发送时用于指示不唤醒终端在DRX的On duration期间内进行PDCCH检测；当该节能信号未被接入网设备发送时用于指示唤醒终端在DRX的On duration期间内进行PDCCH检测。
在该实现方式下，终端对节能信号的检测结果为“未检测到节能信号”时，用于指示唤醒终端在DRX的on duration时间内进行PDCCH的检测；终端对节能信号的检测结果为“检测到节能信号”时，用于指示不唤醒终端在DRX的on duration时间内进行PDCCH的检测。
需要说明的是，针对原因二，也可能采用图6实施例提供的技术方案。
需要说明的是，图6实施例(以及基于图6的可选实施例)还可以与图4实施例(以及基于图4的可选实施例)进行结合实现成为新的实施例，图7实施例(以及基于图7的可选实施例)还可以与图4实施例(以及基于图4的可选实施例)进行结合实现成为新的实施例。
图8示出了本申请另一示意性实施例提供的PDCCH检测方法的流程图。该方法可以由图1中的终端来执行。该方法包括：
步骤401，终端启动节能模式；
步骤402，终端检测节能信号，该节能信号用于指示是否唤醒终端在DRX的激活期时间内进行PDCCH的检测；
当检测到节能信号时，进入步骤403；当未检测到节能信号时，进入步骤404。
步骤403，当检测到节能信号时，根据节能信号的指示进行PDCCH的检测。
当检测到PDCCH时，进入步骤405；当未检测到PDCCH时，进入步骤406。
步骤404，终端在未检测到节能信号时，在DRX的激活期时间内进行PDCCH的检测。
步骤405，当检测到PDCCH时，终端根据PDCCH的调度进行数据传输；
步骤406，当未检测到PDCCH时，终端执行如下三种方式中的其中一种。
方式一，终端进入DRX。
方式二，终端在DRX的激活期定时器(DRX-on duration Timer)超时时启动DRX的不活跃态定时器(DRX-inactivityTimer)，并在DRX的不活跃态定时器超时前进行PDCCH的检测。
方式三，在DRX的激活期定时器超时时启动第一定时器，并在第一定时器超时前进行PDCCH的检测，第一定时器是不同于DRX的不活跃态定时器的定时器。
