用户设备的电池寿命是衡量用户设备的一个重要指标。为此，5G系统引入了一些技术特征用于指示用户设备行为的切换，使得用户设备可以在适当的条件下进入一种省电状态以节省用户设备电能，这种状态的切换涉及到多种配置的改变，包括带宽单元(Bandwidth Part，BWP)的切换(比如，切换至较小的BWP)，物理下行控制信道检测周期的切换(比如，切换至较大周期)，跳过部分物理下行控制信道的监听(英文：PDCCH monitoring skipping)和采用最小调度间隔大于0的跨时隙调度(英文：cross-slot scheduling)等等，触发这些配置改变的信令可以由下行控制信息来承载。
针对如何优化对物理下行控制信道监听行为的指示，相关技术中尚未提供一种合适的解决方案。
为此，本公开实施例提供了一种信道监听的指示方法、装置及存储介质，本公开实施例通过用户设备接收下行控制信息，下行控制信息用于指示是否停止监听物理下行控制信道和/或停止监听物理下行控制信道的时长；使得将指示物理下行控制信道监听行为切换的信息与当前的下行控制信息进行合并，完成物理下行控制信道监听状态的切换指示，进而使得用户设备根据下行控制信息的指示对物理下行控制信道进行监听或者停止监听，无需监听每个物理下行控制信道，降低了用户设备的功耗，优化了对物理下行控制信道的监听行为。
请参考图1，其示出了本公开一个示例性实施例提供的移动通信系统的结构示意图。移动通信系统可以是LTE系统，还可以是5G系统，5G系统又称NR系统，还可以是5G的更下一代移动通信技术系统，本实施例对此不作限定。
可选的，该移动通信系统适用于不同的网络架构，包括但不限于中继网络架构、双链接架构、车联网(Vehicle to Everything，V2X)架构等。
在本公开实施例中，仅以该移动通信系统为NB-IoT系统为例进行说明。该移动通信系统包括：网络侧设备120和用户设备140。
网络侧设备120可以是基站(base station，BS)，也可称为基站设备，是一种部署在无线接入网(Radio Access Network，RAN)用以提供无线通信功能的装置。例如，在2G网络中提供基站功能的设备包括基地无线收发站(base transceiver station,BTS)，3G网络中提供基站功能的设备包括节点B(NodeB)，在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在无线局域网络(wireless local area networks，WLAN)中提供基站功能的设备为接入点(access point，AP)，在5G系统中的提供基站功能的设备为gNB,以及继续演进的节点B(ng-eNB)，本公开实施例中的网络侧设备120还包括在未来新的通信系统中提供基站功能的设备等，本公开实施例对网络侧设备120的具体实现方式不加以限定。接入网设备还可以包括家庭基站(Home eNB，HeNB)、中继(Relay)、微微基站Pico等。

核心网可以是演进型分组核心网(evolved packet core，EPC)、5G核心网(5G Core Network)，还可以是未来通信系统中的新型核心网。5G Core Network由一组设备组成，并实现移动性管理等功能的接入和移动性管理功能(Access and Mobility Management Function，AMF)、提供数据包路由转发和服务质量(Quality of Service，QoS)管理等功能的用户面功能(User Plane Function,UPF)、提供会话管理、IP地址分配和管理等功能的会话管理功能(Session Management Function，SMF)等。EPC可由提供移动性管理、网关选择等功能的MME、提供数据包转发等功能的服务网关(Serving Gateway，S-GW)Serving Gateway、提供终端地址分配、速率控制等功能的PDN网关(PDN Gateway，P-GW)组成。
网络侧设备120和用户设备140通过无线空口建立无线连接。可选的，该无线空口是基于5G标准的无线空口，比如该无线空口是NR；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；或者，该无线空口也可以是基于4G标准(LTE系统)的无线空口。网络侧设备120可以通过无线连接接收用户设备140发送的上行数据。
用户设备140可以是指与网络侧设备120进行数据通信的设备。用户设备140可以经无线接入网与一个或多个核心网进行通信。用户设备140可以是各种形式的用户设备、接入终端设备、用户单元、用户站、移动站、移动台(mobile station，MS)、远方站、远程终端设备、移动设备、终端、终端设备(英文：terminal equipment)、无线通信设备、用户代理或用户装置。用户设备140还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等。图1中仅以示出的用户设备140为手机来举例说明，本实施例对用户设备140的类型不作限定。用户设备140可以通过与网络侧设备120之间的无线连接，接收网络侧设备120发送的下行数据。
需要说明的一点是，当图1所示的移动通信系统采用5G系统或5G的更下一代移动通信技术系统时，上述各个网元在5G系统或5G的更下一代移动通信技术系统中可能会具有不同的名称，但具有相同或相似的功能，本公开实施例对此不作限定。
需要说明的另一点是，在图1所示的移动通信系统中，可以包括多个网络侧设备120和/或多个用 户设备140，图1中以示出一个网络侧设备120和一个用户设备140来举例说明，但本公开实施例对此不作限定。
下面，采用几个示例性实施例对本公开实施例提供的信道监听的指示方法的进行介绍。
请参考图2，其示出了本公开一个示例性实施例提供的信道监听的指示方法的流程图，本实施例以该方法用于图1所示的用户设备中来举例说明。该方法包括以下几个步骤。
步骤201，接收下行控制信息，下行控制信息用于指示是否停止监听物理下行控制信道和/或停止监听物理下行控制信道的时长。
用户设备接收网络侧设备发送的下行控制信息，该下行控制信息用于指示物理下行控制信道监听行为的切换，即是否停止监听物理下行控制信道和/或停止监听物理下行控制信道的时长。
基于下行控制信息的方法中，可以通过在下行控制信息中增加数比特的方式指示物理下行控制信道监听行为的切换，但是下行控制信息的比特大小直接影响着小区的覆盖性能，对于当前已在进行或者已完成部分5G基站部署的运营商来说，直接在下行控制信息中增加多个比特指示域的方式并不可取，因此如何在不增加比特或尽可能少地增加比特的基础上来设计下行控制信息，以指示物理下行控制信道监听行为的切换是需要解决的问题。针对上述问题，本公开实施例中，将指示物理下行控制信道监听行为切换的信息与当前下行控制信息中已有的信息域进行合并，在不增加下行控制信息比特数或仅增加1比特的情况下，完成物理下行控制信道监听行为的切换指示，进而使得用户设备根据业务状态进入到对应合适的节能状态。
当接收到的下行控制信息用于指示停止监听物理下行控制信道时，用户设备停止监听物理下行控制信道，即将物理下行控制信道监听行为切换为跳过部分物理下行控制信道的监听。
用户停止监听物理下行控制信道，包括：用户设备在指定时间段内不对物理下行控制信道进行接收和盲检。
在一个示意性的例子中，以物理下行控制信道周期为1个时隙为例，若用户设备在时隙m收到下行控制信息，且该下行控制信息用于指示停止监听物理下行控制信道且停止监听物理下行控制信道的时长为3个时隙，则用户设备将不会对时隙m+1至m+3中的物理下行控制信道进行接收和盲检，到达时隙m+4时重新开始接收物理下行控制信道。通过这种方式，网络侧设备可以让用户设备在指定时间段内没有数据调度时进入不接收物理下行控制信道的休眠状态，以节省用户设备的电能。
综上所述，本公开实施例通过用户设备接收下行控制信息，下行控制信息用于指示是否停止监听物理下行控制信道和/或停止监听物理下行控制信道的时长；使得将指示物理下行控制信道监听行为切换的信息与当前的下行控制信息进行合并，完成物理下行控制信道监听状态的切换指示，进而使得用户设备根据下行控制信息的指示对物理下行控制信道进行监听或者停止监听，无需监听每个物理下行控制信道，降低了用户设备的功耗，优化了对物理下行控制信道的监听行为。
可选的，下行控制信息中携带有第一调度时延域，或者，下行控制信息的时域资源分配域中携带有第二调度时延；其中，第一调度时延域用于指示是否停止监听物理下行控制信道，第二调度时延用于指示停止监听物理下行控制信道的时长为n个时间单位，n为正整数。下面采用示例性的实施例对几种可能的信道监听的指示方式进行说明。
请参考图3，其示出了本公开另一个示例性实施例提供的信道监听的指示方法的流程图，本实施例以该方法用于图1所示的用户设备中来举例说明。该方法包括以下几个步骤。
步骤301，接收下行控制信息，下行控制信息中携带有第一调度时延域，第一调度时延域所指示的调度时延用于指示是否停止监听物理下行控制信道。
用户设备接收网络侧设备发送的携带有第一调度时延域的下行控制信息。其中，第一调度时延域所指示的调度时延用于指示是否停止监听物理下行控制信道。
第一调度时延域为物理下行控制信道与物理下行共享信道(Physical Downlink Share Channel，PDSCH)之间的时间间隔，第一调度时延域用于指示下行控制信息所调度的PDSCH所在的时域位置。比如，当第一调度时延域所指示的调度时延为1时，物理下行控制信道在时隙m，则对应的物理下行共享信道在时隙m+1中。
用户设备获取最小调度时延的限制值，从接收到的下行控制信息中获取第一调度时延域，判断第一调度时延域所指示的调度时延是否小于最小调度时延的限制值，若第一调度时延域所指示的调度时延小于最小调度时延的限制值，则执行步骤302；若第一调度时延域所指示的调度时延大于或者等于最小调度时延的限制值，则继续监听物理下行控制信道。
最小调度时延为时域资源分配域所能指示的最小K0值，最小K0值用于指示物理下行控制信道与物理下行共享信道直接的时隙距离。比如，物理下行控制信道在时隙n，物理下行共享信道在时隙n+K0。
用户设备获取最小调度时延的限制值，包括：用户设备接收网络侧设备发送的指示信息，该指示 信息中携带有最小调度时延的限制值。
可选的，最小调度时延的限制值包括一个数值或者两个数值。本实施例对此不加以限定。
步骤302，当第一调度时延域所指示的调度时延小于最小调度时延的限制值时，停止监听物理下行控制信道。
当第一调度时延域所指示的调度时延小于最小调度时延的限制值时，用户设备认为发生了错误情况，对应时域资源分配(Time Domain Resource Allocation，TDRA)域的码点为错误码点，用户设备开启跳过部分物理下行控制信道的监听机制，即停止监听物理下行控制信道。
可选的，用户设备在接收到下行控制信息之后的n个时间单位内停止监听物理下行控制信道，n为高层预配置的值或基于下行控制信息确定出的整数。
可选的，n为高层配置的一个或多个值。比如，高层预配置n的值为5。即当第一调度时延域所指示的调度时延小于最小调度时延的限制值时，用户设备在接收到下行控制信息之后的5个时间单位内停止监听物理下行控制信道。本实施例对n的具体取值不加以限定。
停止监听物理下行控制信道的时长为n个时间单位，时间单位为时隙或子帧或秒或毫秒或物理下行控制信道的监听周期或物理下行控制信道的监听时机。本实施例对此不加以限定。
在一种可能的实现方式中，n为预配置的与第一调度时延域所指示的调度时延对应的单位个数。
高层配置不同的错误码点用于指示不同的停止监听物理下行控制信道的时长。用户设备接收预配置的第一对应关系，并存储该第一对应关系，第一对应关系包括第一调度时延域所指示的调度时延与单位个数n之间的对应关系。
在一个示意性的例子中，高层预配置的第一对应关系如表一所示。最小调度时延K0 min的限制值为3，高层预配置第一调度时延域所指示的调度时延K0为0时对应的n为10，第一调度时延域所指示的调度时延K0为1时对应的n为20，时间单位为毫秒。在用户设备被指示K0 min为3之后，若接收到的下行控制信息中携带的K0为0，则用户设备在接收到该下行控制信息之后的10ms内停止监听物理下行控制信道；若接收到的下行控制信息中携带的K0为1，则用户设备在接收到该下行控制信息之后的20ms内停止监听物理下行控制信道。

Figure PCTCN2021074463-appb-000002
在另一种可能的实现方式中，n为下行控制信息的指定域所指示的单位个数。
由于第一调度时延域所指示的调度时延小于最小调度时延的限制值，表示这是一个错误码点，该下行控制信息不能用于数据调度，则该下行控制信息中的其它域可以用于指示停止监听物理下行控制信道的时长，即用于指示停止监听物理下行控制信道的单位个数n。
指定域为下行控制信息中不改变域的位置和长度的比特域，比如，指定域包括下行控制信息中频域资源的比特域或者剩余的比特域。
可选的，用户设备在n个时间单位内停止监听物理下行控制信道之后，重新开始监听物理下行控制信道。
综上所述，本公开实施例还通过接收携带有第一调度时延域的下行控制信息，当第一调度时延域所指示的调度时延小于最小调度时延的限制值时，停止监听物理下行控制信道；利用已引入的跨时隙调度的错误码点来指示是否停止监听物理下行控制信道，不需要增加额外域，降低了下行控制信息的比特开销的同时，进一步优化了对物理下行控制信道的监听行为。
请参考图4，其示出了本公开另一个示例性实施例提供的信道监听的指示方法的流程图，本实施例以该方法用于图1所示的用户设备中来举例说明。该方法包括以下几个步骤。
步骤401，接收下行控制信息，下行控制信息的时域资源分配域用于指示停止监听物理下行控制信道的时长。
用户设备接收下行控制信息，该下行控制信息的时域资源分配域用于指示停止监听物理下行控制信道的时长。
可选的，下行控制信息的时域资源分配域中携带有第二调度时延，第二调度时延用于指示停止监听物理下行控制信道的时间单位n。
第二调度时延为物理下行控制信道与PDSCH之间的时间间隔，第二调度时延用于指示下行控制信息所调度的PDSCH所在的时域位置。比如，当第二调度时延为1时，物理下行控制信道在时隙m，则 对应的PDSCH在时隙m+1中。
步骤402，在接收到下行控制信息之后的n个时间单位内停止监听物理下行控制信道，n为整数。
在本实施例中，停止监听物理下行控制信道的触发条件包括但不限于以下两种可能的实现方式。
在一种可能的实现方式中，当接收到指示信息时停止监听物理下行控制信道，指示信息用于指示对最小调度时延进行限制。
用户设备接收网络侧设备发送的用于指示最小调度时延的限制值的指示信息，即开启跳过部分物理下行控制信道的监听机制，即停止监听物理下行控制信道。
最小调度时延的限制值为最小调度时延的数值。最小调度时延的限制值包括一个数值或者两个数值。本实施例对此不加以限定。
在另一种可能的实现方式中，当下行控制信息中携带有用于指示停止监听物理下行控制信道的比特位时，停止监听物理下行控制信道。
当下行控制信息中携带有用于指示停止监听物理下行控制信道的一个比特位时，用户设备停止监听物理下行控制信道。
用户设备从下行控制信息中获取第二调度时延，根据第二调度时延确定停止监听物理下行控制信道的时长为n个时间单位。用户设备根据触发条件停止监听物理下行控制信道，即在接收到下行控制信息之后的n个时间单位内停止监听物理下行控制信道。
其中，停止监听物理下行控制信道的时长为n个时间单位，时间单位为时隙或子帧或秒或毫秒或物理下行控制信道的监听周期或物理下行控制信道的监听时机。本实施例对此不加以限定。
用户设备根据第二调度时延确定停止监听物理下行控制信道的单位个数n，包括但不限于以下几种可能的实现方式。
在一种可能的实现方式中，n为第二调度时延与预设倍数值的乘积。即用户设备确定第二调度时延与预设倍数值的乘积为单位个数n。
其中，预设倍数值由高层配置。停止监听物理下行控制信道的单位个数n与第二调度时延呈正相关关系。单位个数n与第二调度时延呈倍数关系，即单位个数n为第二调度时延的整数倍，整数倍为预设倍数值。本实施例对此不加以限定。
在一个示意性的例子中，单位个数n与第二调度时延K0的倍数关系如表二所示。其中，预设倍数值X为4，单位个数n的时间单位为时隙或子帧或秒或毫秒或物理下行控制信道的监听周期或物理下行 控制信道的监听时机。当K0为0时对应的n为0，当K0为1时对应的n为4，当K0为2时对应的n为8，当K0为4时对应的n为16。

在另一种可能的实现方式中，n为预配置的与第二调度时延对应的单位个数。即用户设备根据预配置的第二对应关系，将停止监听物理下行控制信道的时间单位的单位个数n确定为与第二调度时延对应的单位个数。其中，第二对应关系为预配置的第二调度时延与单位个数之间的对应关系。
可选的，第二对应关系中存在至少两个第二调度时延各自对应的单位个数是相同的。
在一个示意性的例子中，多个第二调度时延K0与多个单位个数n之间的对应关系如表三所示。其中，单位个数n的时间单位为时隙或子帧或秒或毫秒或物理下行控制信道的监听周期或物理下行控制信道的监听时机。当K0为0或1或2或4时对应的n为X，当K0为6或8或12或16时对应的n为Y。

在另一个示意性的例子中，多个第二调度时延K0与多个单位个数n之间的对应关系如表四所示。其中，单位个数n的时间单位为时隙或子帧或秒或毫秒或物理下行控制信道的监听周期或物理下行控制信道的监听时机。当K0为0或2或6或12时对应的n为X，当K0为1或4或8或16时对应的n为Y。

可选的，第二对应关系包括多个第二调度时延与多个单位个数之间一一对应的关系。
在一个示意性的例子中，多个第二调度时延K0与多个单位个数n之间一一对应的关系如表五所示。其中，单位个数n的时间单位为时隙或子帧或秒或毫秒或物理下行控制信道的监听周期或物理下行控制信道的监听时机。当K0为0时对应的n为A，当K0为1时对应的n为B，当K0为2时对应的n为4，当K0为4时对应的n为D；当K0为6时对应的n为E，当K0为8时对应的n为F，当K0为12时对应的n为G，当K0为16时对应的n为H。

用户设备在接收到下行控制信息之后的n个时间单位内停止监听物理下行控制信道。用户设备在n个时间单位内停止监听物理下行控制信道之后，重新开始监听物理下行控制信道。
在一个示意性的例子中，基于上述表五所示的对应关系，以n的时间单位为时隙为例，如图5所示，用户设备在时隙m接收到下行控制信息，该下行控制信息的时域资源分配域中携带的第二调度时延K0为2，该第二调度时延K0用于指示n为4，即停止监听PDCCH的时长为4个时隙。用户设备根据该下行控制信息，在时隙m+2上接收PDSCH，在时隙m+1至m+4内停止监听PDCCH，达到时隙m+5时重新开始监听PDCCH。
本公开实施例还通过利用下行控制信息的时域资源分配域中携带有第二调度时延，第二调度时延用于指示停止监听物理下行控制信道的时间单位n，不需要增加或仅增加1比特的额外域，降低了下行控制信息的比特开销的同时，进一步优化了对物理下行控制信道的监听行为。
