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。
应当理解的是，在本文中提及的“若干个”是指一个或者多个，“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。为了便于理解，下面先对本公开涉及的一些应用场景进行简单介绍。
请参考图1，其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示，无线通信***是基于蜂窝移动通信技术的通信***，该无线通信***可以包括：若干个终端110以及若干个基站120。
其中，终端110可以是指向用户提供语音和/或数据连通性的设备。终端110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110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，UE)。或者，终端110也可以是无人飞行器的设备、车载设备等。
基站120可以是无线通信***中的网络侧设备。其中，该无线通信***可以是***移动通信技术(the 4th generation mobile communication，4G)***，又称长期演进(Long Term Evolution，LTE)***；或者，该无线通信***也可以是5G***，又称新空口(new radio，NR)***。或者，该无线通信***也可以是5G***的再下一代***。
其中，基站120可以是4G***中采用的演进型基站(eNB)。或者，基站120也可以是5G***中采用集中分布式架构的基站(gNB)。当基站120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120的具体实现方式不加以限定。
基站120和终端110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***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。
可选的，上述无线通信***还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信***中的核心网设备，比如，该网络管理设备130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130的实现形态，本公开实施例不做限定。
在一种可能实现的方式中，上述无线通信***中，终端110在PDCCH中传输调度数据时，需要对PDCCH进行检测，从而接收PDCCH中传输的调度数据。例如，终端在监测PDCCH时，如果此时PDCCH中传输有基站下发的第一调度数据，那么终端便可以接收到该基站下发的第一调度数据。在NR***中，终端110在PDCCH中传输的调度数据之前，不需要时时监测PDCCH，而是在规定的，某些特定的时间内监测PDCCH。可选的，本公开实施例中，将该某些特定的时间命名为活跃时间(active time)。
在一种可能实现的方式中，该活跃时间可以是不连续接收(Discontinuous Reception，DRX)中的持续时间(On Duration Time)，也可以是基站所配置的PDCCH中的监听时间(Monitoring Occasions)。即，当活跃时间到来时，终端会唤醒开始监测PDCCH中传输的调度数据。在这种情况下，当终端在到来的活跃时间内没有相应的业务时，如果此时终端开始在活跃时间内监测PDCCH，就会白白浪费功率，造成不必要的功率损失。
为了避免这种情况的出现，在本公开提供的一种方案中，为了进一步节约终端的功耗，可以在活跃时间到来之前引入功率节省信号，提示用户在active  time唤醒以监测PDCCH，或是，在active time不用唤醒，可以继续保持睡眠(sleep)。即，该功率节省信号可以指示终端在活跃时间内是否监测PDCCH。可选的，当终端接收到的功率节省信号指示终端不在当前的活跃时间内开始监测PDCCH中传输的调度数据时，终端可以继续等待下一个功率节省信号，从而避免终端在没有传输调度数据的时间段内继续监测PDCCH，造成功率的浪费。
此外，在NR中，当终端唤醒进行业务交互时，对于PDCCH监测的频率，终端所需要监测(monitor)的带宽，接收或发送天线的数量等信息都可以灵活配置。比如当业务比较密集，数据量大时，可以为终端配置大带宽，更多天线和更密集的PDCCH监测。同时，这些配置会消耗终端大量的电量。反之，当业务比较稀疏时，基站可以调整配置，比如让终端监测小带宽，用较少的天线接收，和/或配置更加稀疏的PDCCH监测，在这种情况下可以使用功率节省信号对这些配置进行切换或者是重配置。
当基站单方面向终端发送功率节省信号时，可能存在发送错误的情况，此时终端无法正确接收功率节省信号，但是基站却不清楚终端的接收情况，会造成基站和终端对于后续操作的理解不一致，造成后续的通信失败。
为了解决上述问题，本公开所示的方案，还提供一种对功率节省信号进行HARQ反馈的方案，对上述的功率节省信号的发送流程进行优化，使得基站能得知终端的接收状态，避免造成基站和终端对后续操作的理解不一致的情况。
请参考图2，其示出了本公开实施例提供的一种HARQ反馈方法的方法流程图，该方法可以应用于图1所示的无线通信***中，由该***中的终端执行，如图2所示，该方法可以包括如下几个步骤。

综上所述，基站向终端发送功率节省信号后，可以接收终端对功率节省信号进行HARQ反馈时发送的反馈信息，以使得基站能够及时获知终端是否成功接收功率节省信号，保证基站和终端对于后续功率节省操作的理解相一致，提高基站和终端后续根据功率节省操作进行通信的成功率。
图4是根据一示例性实施例示出的一种HARQ反馈方法的方法流程图，如图4所示，以基站发送的功率节省信号对应的至少两个终端中包含目标终端时，该HARQ反馈方法可以应用于图1所示的无线通信***中，且由该***中的基站和终端执行，可选的，该终端可以是目标终端，该方法可以包括如下几个步骤。
在步骤401中，基站向终端发送功率节省信号，相应的，终端接收该功率节省信号。
其中，该功率节省信号用于指示终端执行功率节省相关的动作。
在一种可能的实现方式中，上述功率节省相关的动作，可以包括以下动作：
1)检测和接收用于数据调度的物理下行控制信道PDCCH。
例如，当后续一段时间内基站需要对终端进行数据调度，比如，基站和终端之间后续需要进行业务数据的传输，此时，基站可以向终端发送功率节省信号，以指示终端在对应的active time唤醒以检测和接收PDCCH。
2)跳过用于数据调度的PDCCH的检测和接收。
例如，当后续一段时间内基站不需要对终端进行数据调度，比如，基站和终端之间后续不需要进行业务数据的传输，此时，基站可以向终端发送功率节省信号，以指示终端在对应的active time继续休眠，以节省终端的电量。
3)调整通信的相关参数，其中，所述相关参数包括所述终端使用的带宽值，所述终端使用的天线数，PDCCH的候选位置数中的至少一种。
例如，当后续一段时间内基站与终端之间的需要传输的数据量上升，则基站可以向终端发送功率节省信号，以指示终端使用更高的带宽值、更多的天线数量以及监测更多的PDCCH候选位置，从而适配后续的业务数据传输。
再例如，当后续一段时间内基站与终端之间的需要传输的数据量下降，则基站可以向终端发送功率节省信号，以指示终端使用较低的带宽值、较少的天线数量以及监测较少的PDCCH候选位置，以节省终端的电量。
在步骤402中，在根据对该功率节省信号的接收结果确定向基站发送反馈消息时，终端获取用于对该功率节省信号进行HARQ反馈的PUCCH资源。
终端在对功率节省信号进行HARQ反馈时，可以有以下几种反馈方式：
1)在接收该功率节省信号成功时，终端向基站发送确认应答ACK反馈消息；当接收该功率节省信号失败时，终端向该基站发送否定应答NACK反馈消息。
在一种可能的实现方式中，终端无论是否成功接收该功率节省信号，都会针对该功率节省信号向基站发送反馈信息。
比如，当终端接收功率节省信号成功后，确定向基站发送ACK，反之，当终端接收功率节省信号失败后，确定向基站发送NACK。
或者，终端也可以在接收功率节省信号成功后，确定向基站发送NACK，反之，当终端接收功率节省信号失败后，确定向基站发送ACK。
2)当接收该功率节省信号成功时，向基站发送确认应答ACK反馈消息； 当接收该功率节省信号失败时不反馈；
在另一种可能的实现方式中，终端只有在接收该功率节省信号成功时，才针对该功率节省信号向基站发送反馈信息。
比如，当终端接收功率节省信号成功后，确定向基站发送ACK。
或者，当终端接收功率节省信号成功后，也可以确定向基站发送NACK。
3)当接收该功率节省信号成功时不反馈；当接收该功率节省信号失败时，向该基站发送否定应答NACK反馈消息。
在另一种可能的实现方式中，终端只有在接收该功率节省信号失败时，才针对该功率节省信号向基站发送反馈信息。
比如，当终端接收功率节省信号失败后，确定向基站发送NACK。
或者，当终端接收功率节省信号失败后，也可以确定向基站发送ACK。
在一种可能的实现方式中，在获取用于对该功率节省信号进行HARQ反馈的物理上行链路控制信道PUCCH资源时，终端可以获取PUCCH资源集合，该PUCCH资源集合是由高层信令配置给该终端可用的PUCCH资源组成的集合；并根据该功率节省信号携带的PUCCH资源指示，和/或，该功率节省信号的物理资源位置信息，从该PUCCH资源集合中获取用于对该功率节省信号进行HARQ反馈的PUCCH资源。
相应的，在这种可能的实现方式中，基站在向终端发送功率节省信号之前，还通过高层信令向该终端配置PUCCH资源集合。
例如，基站可以通过高层信令提前为终端配置一个PUCCH资源集合，集合中每个PUCCH资源都有一个对应的编号，比如{N_PUCCH1，N_PUCCH2，N_PUCC3,..,}。当PUCCH集合中的PUCCH资源个数小于或等于8时，PUCCH资源编号可以由功率节省信号中3bit的信息域直接指示。当PUCCH资源集合中的PUCCH数目大于8时，可以由PDCCH所在的最小的控制信道单元(Control Channel Element，CCE)编号和功率节省信号中3bit信息域的指示信息推导出来，该推导过程的公式可以如下：
Figure PCTCN2019090581-appb-000001
其中，R PUCCH为所配置的PUCCH资源集合的大小，N CCE,p为PDCCH所 在的控制域所占的CCE的总数，n CCE,p为PDCCH所在的最小的CCE编号，Δ PRI是功率节省信号中3bit信息域所指示的值。
其中，上述功率节省信号中3bit信息域所指示的值就是上述PUCCH资源指示，PDCCH所在的最小的CCE编号为功率节省信号的物理资源位置信息。
可选的，除了通过功率节省信号携带上述PUCCH资源指示之外，基站也可以通过下行控制信息(Downlink Control Information，DCI)向终端发送该PUCCH资源指示。
或者，对于给定的PUCCH资源集合，终端也可以根据PDCCH所在的最小CCE编号推导获得用于对功率节省信号进行HARQ反馈的PUCCH资源。
在另一种可能的实现方式中，在获取用于对该功率节省信号进行HARQ反馈的物理上行链路控制信道PUCCH资源时，终端可以获取由高层信令配置该终端的，用于对该功率节省信号进行HARQ反馈的PUCCH资源。
相应的，在这种可能的实现方式中，基站向终端发送功率节省信号之前，还通过高层信令向该终端配置用于对该功率节省信号进行HARQ反馈的PUCCH资源。
比如，基站可以预先通过是高层信令为终端配置一个固定的PUCCH资源。当终端确定需要针对功率节省信号进行反馈时，可以直接获取该PUCCH资源。
在步骤403中，终端获取对该功率节省信号进行HARQ反馈时发送的反馈消息的发送时间点。
在一种可能的实现方式中，终端在获取该反馈消息的发送时间点时，可以获取参考时间点，该参考时间点是该功率节省信号的传输结束时间点；并将处于该参考时间点之后，且与该参考时间点之间的间隔为指定间隔的时间点获取为该发送时间点。
可选的，该指定间隔为预设的时间间隔；
或者，该指定间隔是由高层信令配置的时间间隔；
或者，该指定间隔是该功率节省信号中携带的时间间隔。
比如，终端可以将功率节省信号的传输结束时间点作为参考点，间隔固定时间间隔之后针对该功率节省信号向基站进行HARQ反馈，该固定时间间隔可以是终端中预先设置的时间间隔(比如，该时间间隔可以由协议规定)，或者，该固定时间间隔可以是基站预先通过高层信令配置的时间间隔。
或者，终端也可以将功率节省信号的传输结束节时间点作为参考点，间隔 固定时间间隔之后针对该功率节省信号向基站进行HARQ反馈，该时间间隔可以是一个针对该功率节省信号单独配置的时间间隔，比如，该时间间隔可以由功率节省信号承载。
在步骤404中，终端根据该对该功率节省信号进行HARQ反馈的PUCCH资源，以及该发送时间点获取对该功率节省信号进行HARQ反馈所使用的HARQ反馈资源。
终端获取到用于HARQ反馈的PUCCH资源以及反馈的时间点之后，即可以确定发送反馈信息所使用的HARQ反馈资源。
相应的，基站也可以通过类似的方式获取终端可能发送HARQ反馈信息所使用的该HARQ反馈资源，以便后续接收终端针对该功率节省信号的反馈信息。
在步骤405中，终端在该HARQ反馈资源上向基站发送该反馈消息，相应的，基站在该HARQ反馈资源接收该反馈消息。
可选的，在根据对该功率节省信号的接收结果进行HARQ反馈时，终端可以当该功率节省相关的动作为指定动作时，根据对该功率节省信号的接收结果进行HARQ反馈。
其中，该指定动作可以是该终端中预先设置的动作；或者，该指定动作可以是由基站配置的动作。
在一种可能的实现方式中，终端中可以预先设置需要进行HARQ反馈的功率节省信号对应的指定动作。比如，通信标准协议可以强制规定需要对哪些功率节省相关的动作对应的功率节省信号的接收情况进行反馈。也就是说，通信标准协议可以对某些类型的功率节省信号进行规定，比如规定当功率节省信号用于唤醒终端监听PDCCH，或者，功率节省信号用于改变相关参数时，终端必须对功率节省信号进行HARQ反馈，而当功率节省信号用于指示终端休眠，以跳过PDCCH监听和接收时，终端不需要对功率节省信号进行HARQ反馈。
在另一种可能的实现方式中，基站可以针对是否进行反馈进行配置，比如基站可以通过无线资源控制(Radio Resource Control，RRC)信令对终端配置需要进行HARQ反馈的功率节省信号对应的指定动作。其中，基站在进行配置时，可以对不同功能的功率节省信号进行集中配置。比如，基站可以配置所有功能的功率节省信号都需要进行反馈，或者，都不需要进行反馈。或者，基站也可以对不同功能的功率节省信号分别进行配置，比如配置当功率节省信号用于唤醒终端监听PDCCH，或者，功率节省信号用于改变相关参数时，终端必须对功 率节省信号进行HARQ反馈；并且，基站可以配置当功率节省信号用于指示终端休眠，以跳过PDCCH监听和接收时，终端不需要对功率节省信号进行HARQ反馈。
在步骤406中，当该反馈消息指示该终端接收该功率节省信号成功时，基站执行与该功率节省相关的动作对应的调度操作或者传输调整操作。
在本公开实施例中，基站需要在终端对功率节省信号进行反馈后，才进行相应的调度或者调整。比如，当终端对需要用于唤醒终端监听PDCCH的功率节省信号进行反馈时，基站根据反馈信息确定终端已经成功接收到该功率节省信号后，基站才对该终端进行相应的调度；如果当前反馈信息指示用户并未成功接收到该功率节省信号，则基站不会进行相应的调度。又比如，当终端对进行相关参数调整的功率节省信号进行反馈时，基站根据反馈信息确定终端已经成功接收到该功率节省信号后，基站会根据新配置的参数进行数据的传输，否则还是按照原来的方式对数据传输进行调度。
综上所述，终端接收功率节省信号后，可以根据对功率节省信号的接收结果进行HARQ反馈，相应的，基站接收到终端的反馈信息，并确定终端接收到功率节省信号之后，才执行相应的调度或者调整，以使得基站能够及时获知终端是否成功接收功率节省信号，保证基站和终端对于后续功率节省操作的理解相一致，提高基站和终端后续根据功率节省操作进行通信的成功率。
