具体实施方式
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图2，其示出了本申请实施例提供的一种无线通信***的结构示意图。如图2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，终端)。或者，终端110也可以是无人飞行器的设备。或者，终端110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，终端110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。
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5G NR***。或者，该无线通信***也可以是5G***的再下一代***。其中，5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
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，本申请实施例对基站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。
在一些实施例中，终端110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，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，本申请实施例不做限定。
如图3所示，本实施例提供一种唤醒信号的变更处理方法，可以应用于基站中，所述方法可包括：
步骤S110：下发变更通知，其中，所述变更通知，至少用于指示唤醒信号的配置变更。
在本实施例中，所述变更通知可以通过基站下发的任意指令来携带，例如，广播指令、组播指令或单播指令。
该变更通知，用于变更所述唤醒信号的配置，唤醒信号的配置变更包括以下至少一种情况：
有唤醒信号配置和无唤醒信号配置之间的变更；
唤醒信号的图样变更。
所述变更通知，至少指示上述任意一种变更方式。
所述变更通知，可以是根据当前唤醒信号的使用需求动态确定的，从而通过变更通知的下发，使得唤醒信号的配置与当前使用需求相适配，从而减少了唤醒信号的配置与实际使用需求不一致导致的各种问题，例如，不必要的唤醒信号下发和监听，及唤醒信号的图样过于稀疏等问题。
唤醒信号的图样表示的所述唤醒信号的频度；所述唤醒信号的频度为：所述唤醒信号与所述唤醒时段的映射关系。所述唤醒信号与所述唤醒时段之间的映射关系为：1：N，N可为0或正整数。
所述变更通知还可包括：生效所述唤醒信号的配置变更的变更生效 信息等；所述变更生效信息包括但不局限于一个生效的延时量等。
所述变更通知还可包括：
在一些实施例中，所述变更通知，包含以下至少之一：
图样变更信息，用于变更所述唤醒信号生效的图样，其中，在不同所述图样中，所述唤醒信号与唤醒时段的映射关系不同；
使能变更信息，其中，所述使能变更信息，用于使能所述唤醒信号的候选图样或去使能所述唤醒信号的当前生效图样。
在一些实施例中，所述变更通知还可包括：
变更生效信息，其中，所述变更生效信息，用于指示所述唤醒信号变更的生效信息。即，所述变更通知还包括：所述变更生效信息。
在另一些实施例中，所述变更生效信息不携带在所述变更通知内，而是携带在其他信令中，例如，无线资源控制(Radio Resource Control，RRC)信令中下发给终端。
在还有一些实施例中，所述变更生效消息可为预先设定的，被基站和终端等多个通信方所预先知晓的，例如，预先通过协议规定的，或者，预先在广播消息中下发的等。
在一些实施例中，所述映射关系可为：1：N，N可为0或者正整数；当N为0时，基站不下发WUS，终端根据原定的DRX周期，在唤醒时段进入到唤醒状态，在休眠时段进入到休眠状态。
当所述N为1时，基站针对每一个DRX周期都配置有一个唤醒信号的下发时刻，然后根据数据传输的需求，在该下发时刻下发或不下发所述WUS，终端在每一个唤醒信号的监听时刻都会监听WUS，然后根据监听结果，确定在该DRX周期的唤醒时段的终端状态，例如，监听到则保持唤醒状态，若未检测到WUS信号则在一个唤醒时段保持休眠状态。
但是所述唤醒信号与所述唤醒时段之间的映射关系不限于上述1：N 的映射关系。
在一些实施例中，所述变更生效信息包含：
第一生效方式信息，用于指示在下发所述变更通知之后，以第一延时生效方式生效所述唤醒信号的配置变更；
或者，
第二生效方式信息，用于指示在下发所述变更通知之后，以第二延时生效方式生效所述唤醒信号的配置变更；第二延时生效方式和第一延时生效方式不同；
或者，
第三生效方式信息，用于指示在下发所述变更通知之后，立即生效所述唤醒信号的配置变更。
在一些实施例中，所述变更通知还携带有变更生效信息，该变更生效信息可用于指示唤醒信号的配置变更的生效方式。
在本实施例中所述唤醒信号的配置变更的生效方式包含有三种：一种是立即生效方式，另外两种是延迟生效方式。
立即生效方式即为所述第三生效方式信息指示的生效方式，如此，基站下发完所述变更通知之后，基站立即生效所述变更通知所指示的配置变更。终端接收到所述变更通知之后，会立即生效所述变更通知所指示的配置变更。
第一生效方式信息和第二生效方式分别对应的是第一延时生效方式和第二延时生效方式。所述第一延时生效方式是在前一个唤醒信号的生效范围结束之后生效所述变更通知所指示的唤醒信号配置，而第二延时生效方式是基站指示了一个延时时长，例如，通过一个或多个比特显性或隐性指示一个延时时长(即所述第二延时生效方式延时的时长)。基站在下发所述变更通知之后，延时所述第二延时生效方式延时的时长之后， 生效变更通知指示的唤醒信号的配置变更；终端在接收到所述变更通知之后，延时所述生效方式延时的时长之后，生效所述变更通知所指示的唤醒信号的配置变更。
总之，本申请实施例中提供了多种所述唤醒信号的配置变更的生效方式，如此，方便基站根据生效需求选择合适的生效方式进行唤醒信号的配置变更。
在本实施例中，所述第一延时生效方式和所述第二生效方式的延时时长确定依据是不同的，第一延时生效方式是根据所述变更通知的下发时刻和变更前唤醒信号的图样确定的延时，而第二延时生效方式是基站指示的时长确定延时。
在一些实施例中，所述第一延时生效方式对应的第一延时可等于所述第二延时生效方式对应的第二延时；在另一些实施例中，所述第二延时也可以不等于所述第一延时。
在一些实施例中，当所述变更生效信息包括所述第二生效方式信息时，所述变更生效信息还包括：延时时长信息。
所述延时时长信息可为各种指示信息，例如，可以通过一个或多个比特，指示延时的DRX周期个数；也可以直接指示延时的时长。例如，在一些实施例中，所述延时时长信息，用于指示所述第二延时生效方式延时的时长T。
当基站指示第二延时生效方式延时的时长T时，基站可以根据当前唤醒信号的配置变更的紧急度和/或变更通知的下发时刻与变更前唤醒信号的图样，综合确定所述时长T。
该时长T的取值可为0或正数。
通过两种延时生效方式的引入，可以使得基站在有些信令有空闲比特时，提前下发所述变更通知，而无需等到需要变更唤醒信号的配置时 才进行所述变更通知的下发。在一些实施例中，所述方法还包括：
当所述变更生效信息包含所述第一生效方式信息时，根据所述变更通知的下发时刻与变更前所述唤醒信号的图样，生效所述唤醒信号的配置变更。
在本实施例中，所述唤醒信号的配置至少包括唤醒信号的图样，不同的图样，唤醒信号与唤醒时段之间的映射关系是不同的。
在本变更通知下发之前，基站下发的唤醒信号在生效，如此，需要结合所述变更通知的下发时刻是否在前一个下发的唤醒信号的生效范围内，确定是否需要延时所述唤醒信号的配置变更，或者，延迟多久所述唤醒信号的配置变更。
如图4A和4B所示，若采用第一延时生效方式信息指示的第一延时生效，若变更通知在前一个唤醒信号的生效范围内下发，则需要延迟到前一个唤醒信号的生效范围结束之后才生效唤醒信号的配置变更。
在图4A中唤醒信号与唤醒时段之间的映射关系为1:1；在图4B中唤醒信号与唤醒时段之间的映射关系为1：P，其中，P为等于或大于2的正整数。
图4A中展示有3种情况：
情况1：变更通知的下发时刻在前一个唤醒信号的下发时刻之后，且在前一个唤醒信号生效的唤醒时段之前；在情况1下，变更通知的下发时刻对应于箭头A1；图4A中箭头B1和箭头B2表示唤醒信号的下发时刻或监听时刻。由于图4A展示的唤醒信号与唤醒时段之间的映射关系为1:1，因此相邻两个唤醒信号之间(即箭头B1和箭头B2之间)仅相隔了一个DRX周期。
情况2：变更通知的下发时刻在前一个唤醒信号生效的唤醒时段内；在情况2下，变更通知的下发时刻对应于箭头A2；
情况3：变更通知在下发时刻在前一个唤醒信号生效范围内的两个唤醒时段之间，在情况3下，变更通知的下发时刻对应于箭头A3。
图4B中展示有3种情况：
情况1：变更通知的下发时刻在前一个唤醒信号的下发时刻之后，且在前一个唤醒信号生效的唤醒时段之前；在情况1下，变更通知的下发时刻对应于箭头A1；图4B中箭头C1和箭头C2表示唤醒信号的下发时刻或监听时刻。由于图4B所示为唤醒信号和唤醒时段之间的映射关系为1：P，故在两个唤醒信号之间至少间隔了两个DRX周期。
情况2：变更通知的下发时刻在前一个唤醒信号生效的唤醒时段内；在情况2下，变更通知的下发时刻对应于箭头A2；
情况3：变更通知在下发时刻在前一个唤醒信号生效范围内的两个唤醒时段之间，在情况3下，变更通知的下发时刻对应于箭头A3。
针对图4A和图4B分别所示的三种情况，由于变更通知都是在前一个唤醒信号的生效范围内下发的，如此，需要延迟到前一个唤醒信号生效范围结束后生效所述唤醒信号的配置变更。参照图4A中，即在箭头B2之后在生效变更通知所指示的唤醒信号配置变更。
在一些实施例中，所述当所述变更生效信息包含所述第一生效方式信息时，以所述第一延时生效方式根据所述变更通知的下发时刻与变更前所述唤醒信号的图样，生效所述唤醒信号的配置变更，包括：
当所述变更生效信息包含所述第一生效方式信息时，根据所述第一延时生效方式，若所述变更通知的下发时刻为变更前的所述唤醒信号的下发时刻，生效所述唤醒信号的配置变更；
或者，
当所述变更生效信息包含所述第一生效方式信息时，根据所述第一延时生效方式，若所述变更通知的下发时刻为变更前所述唤醒信号的生 效时刻，在变更前所述唤醒信号的下一个下发时刻，生效所述唤醒信号的配置变更。
若变更生效信息包含第一生效方式信息，但是变更通知的下发时刻恰好是变更前唤醒信号的下发时刻，则基于第一延时生效方式可以及时生效唤醒信号的配置变更。
若变更生效信息包含第一生效方式信息，但是变更通知的下发时刻为变更前唤醒信号的生效范围内，则基于第一延时生效方式，需要在变更前唤醒信号的图样所对应的前一个唤醒信号的生效范围结束之后，在生效所述变更通知所指示的唤醒信号的配置变更。
在一些实施例中，如图5所示，在所述下发变更通知之前，所述方法还包括：
步骤S100：下发所述唤醒信号的候选图样。
所述候选图样可包括：唤醒信号的配置变更后所对应的图样。
在一些实施例中，当所述唤醒信号的配置变更使得所述唤醒信号和唤醒时段之间的映射关系从1：N变更为1:1，则所述变更生效信息包含：所述第一生效方式信息或所述第二生效方式信息；
当所述唤醒信号的配置变更使得所述唤醒信号和唤醒时段之间的映射关系从1：1变更为1：N，所述变更生效信息包含：所述第一生效方式信息或所述第二生效方式信息；
当所述使能变更信息指示去使能所述唤醒信号的当前生效图样时，所述变更生效信息包含：所述第一生效方式信息或所述第二生效方式信息。
即当唤醒信号与唤醒时段之间的映射关系发生上述变化，或则去使能当前唤醒信号的生效图样时，不采用第三生效方式信息所指示的生效方式，而是优先采用第一生效方式信息指示的第一生效方式，或者，所 述第二生效方式信息指示的第二生效方式。
在一些实施例中，所述下发所述唤醒信号的候选图样，包括：
下发所述唤醒信号的一套候选图样；
或者，
下发所述唤醒信号的至少两套候选图样，其中，在不同所述候选图样中，所述唤醒信号与唤醒时段的映射关系不同。
若在变更通知下发之前下发的候选图样可为一套或多套。
在一些实施例中，所述下发唤醒信号的监听通知，包括：
利用媒体访问控制MAC控制单元CE下发所述变更通知；
或者，
利用下行控制信息DCI下发所述变更通知。
所述MAC CE包含逻辑信道标识，其中，所述逻辑信道标识，能够指示所述MAC CE携带有所述变更通知。
携带不同内容的MAC CE所包含的逻辑信道标识(Identification，ID)不同。在本实施例中，所述MAC CE携带的逻辑信道ID可为专门设置用于指示携带有变更通知的逻辑信道ID。
所述逻辑信道ID可以用于与物理信道进行映射，此处复用为指示所述MAC CE是否携带变更通知。例如，通过设定携带有所述变更通知的MAC CE的备选逻辑信道标识，再从备选逻辑信道标识中选择一个目标逻辑信道标识，最后利用目标逻辑信道标识所对应的MAC CE携带所述变更通知。
该逻辑信道ID可携带在MAC CE的头部，如此，终端接收到MAC CE可以通过解码MAC CE的头部就知道当前MAC CE是否携带有所述变更通知。
在一些实施例中，所述变更通知可携带在所述MAC CE的头部，也 可以携带在所述MAC CE的正文中。在MAC CE中正文位于所述头部之后。
所述MAC CE可以为专用发送所述变更通知的MAC CE，也可以是与其他消息共用的MAC CE。例如，其他消息包括但不限于指示终端所接入小区的小区标识等信息。
在一些实施例中，在下发变更通知时，所述步骤S110可包括：
当所述唤醒信号的候选图样为一套时，利用所述MAC CE或者所述DCI下发所述唤醒信号的使能变更通知；
或者，
当所述唤醒信号的候选图样为多套时，利用所述MAC CE或者所述DCI下发所述唤醒信号的多套所述候选图样中使能的所述候选图样。
针对候选图样仅为一套时，可以通过使能变更通知，可以使能或去使能这一套唤醒信号的图样。若一套唤醒信号的图样被使能了，则基站会按照该图样下发所述唤醒信号，而终端会根据该图样监听所述唤醒信号。
若一套唤醒信号的图样被去使能了，则基站不再根据该图样下发唤醒信号，同时终端也停止基于该图样监听唤醒信号。
在所述候选图样有多套时，可以利用所述MAC CE选择一套候选图样使能的唤醒信号。
在另一些实施例中，候选图样有多套时，同样可以利用MAC CE通过使能变更通知的下发，去使能当前生效的唤醒信号的图样。
在另一些实施例中，所述变更通知还可以直接携带变更生效的唤醒信号的图样。如此，终端在接收到这种变更通知之后，直接根据变更通知中携带的唤醒信号的图样，进行唤醒信号的配置变更，如此，基站不用预先下发唤醒信号的候选图样。
在一些实施例中，所述当所述唤醒信号的候选图样为一套时，利用所述MAC CE或者所述DCI下发所述唤醒信号的使能变更通知，包括：
当所述唤醒信号的候选图样为一套时，利用所述MAC CE或者所述DCI中的1个指示比特的第一比特值，下发一套所述唤醒信号的使能变更通知；
或者，
当所述唤醒信号的候选图样为一套时，利用所述MAC CE或者所述DCI中的1个指示比特的第二比特值，下发一套所述唤醒信号的去使能变更通知；
或者，
所述当所述唤醒信号的候选图样为多套时，利用所述MAC CE或者所述DCI中的P个比特的不同比特值，使能多套所述候选图样中的一套，包括：
当所述唤醒信号的候选图样为多套时，利用所述MAC CE或者所述DCI中的P个比特的不同比特值，使能多套所述候选图样中的一套。
在本实施例中，MAC CE或者所述DCI携带有一个或多个指示比特，这些指示比特的比特值对应于前述变更通知。
仅有一套候选图样时，可以利用一个比特的两个比特值，即“0”和“1”指示是使能还是去使能下发的所述唤醒信号的图样。
如果候选图样有多套，则可以利用一个比特位图来指示各个候选图样的那一套候选图样为变更后的唤醒信号的图样。
在一些实施例中，所述P个比特可为比特位图，如此，有X个候选图样，则P等于X。在另一些实施例中，P个比特有可以指示大于P个候选图样。例如，2个比特的4个比特值组合，可以指示4套候选图样中任意一套候选图样。例如，“00”指示生效第一套候选图样；再例如，“11” 指示生效最后一套候选图样。
若通过MAC CE或者DCI下发所述变更通知，则无需接收终端的接收反馈，就可以变更通知或者默认生效方式，生效所述唤醒信号的配置变更。在一些实施例中，所述方法还包括：
步骤S120：接收基于所述DCI下发的所述变更通知的反馈信息；
步骤S130：在所述反馈信息指示确认收到所述变更通知之后，生效所述唤醒信号的配置变更。
所述反馈信息包括：确认符(ACK)或否认符(NACK)，若基站接收到ACK，则表示终端接收到了变更通知，若基站接收到NACK，则表示终端未正确接收变更通知。
若确认接收到了变更通知，则基站和终端生效所述唤醒信号的配置变更。例如，按照默认方式或者所述变更通知携带的变更生效方式指示的生效方式指示方式，生效所述唤醒信号的配置变更。所述默认方式可为前述三种生效方式的任意一种。默认生效方式可为预先协商的生效方式，也可以是协议规定的生效方式。
若基站接收到了NACK，则基站可能会重新下发变更通知，重新下发的变更通知的内容，可以与终端未成功接收的变更通知的内容相同，或不同；但是两个变更通知指示的配置变更可相同。例如，变更通知携带有第二生效方式信息，如果重新下发基站可能需要重新计算并指示T，此时两次下发的变更通知的内容不同，但是可能指示的在同一个时刻点生效唤醒信号的同一种配置。
在一些实施例中，所述方法还包括：
接收所述唤醒信号的变更辅助信息；
所述步骤S110可包括：
根据所述变更辅助信息，下发所述变更通知。
所述变更辅助信息可包括终端上报的建议的唤醒信号配置。例如，终端可以根据自身的功耗及数据传输需求，建议一种唤醒信号配置。
如此，终端在下发变更通知时，可以终端网络侧需求和终端的需求，尽可能的下发同时满足网络侧和终端侧需求的唤醒信号的配置变更。
所述变更辅助信息包括但不限于：指示唤醒信号的图样的建议指示，或者，使能或去使能唤醒信号图样的使能指示。
在一些实施例中，所述变更辅助信息可以包括：变更所述唤醒信号的各种依据信息，例如，所述变更辅助信息可包括：业务传输频繁度，若业务传输频繁度高，则可能需要降低一个所述唤醒信号对应的唤醒时段的个数；若业务频繁度低，可能需要增加一个所述唤醒信号对应的唤醒时段的个数。
如图6所示，本实施例提供一种唤醒信号监听方法，包括：
步骤S210：接收变更通知；
步骤S220：根据所述变更通知，生效唤醒信号的配置变更。
本申请实施例提供的方法，应用终端中，该终端可为各种类型的终端，例如，MTC终端。
终端会接收到基站下发的变更通知，然后根据变更通知生效唤醒信号的配置变更。若生效了一个配置变更之后，终端会根据变更后的唤醒信号的配置监听唤醒信号。
在一些实施例中，所述步骤S220可包括以下至少之一：
根据所述变更通知包含的图样变更信息，生效所述图样变更信息所指示生效的图样，其中，不同所述图样指中唤醒信号与唤醒时段的映射关系不同；
根据所述变更通知包含的使能变更信息，使能所述唤醒信号的候选图样；根据所述变更通知包含的使能变更信息，去使能所述唤醒信号的 生效图样。
在一些实施例中，通过RRC信令在下发所述变更通知之前、下发变更通知之时或下发所述变更通知之后接收所述变更生效信息。
在另一些实施例中，所述变更通知还包括：所述变更生效信息，如此，由变更通知携带变更生效信息下发。
在一些实施例中，所述步骤S220还可包括：
根据所述变更通知包含的变更生效信息，生效所述唤醒信号的配置变更。
在一些实施例中，所述方法还包括：获取所述变更生效信息。
所述获取变更生效信息包括以下之一：
接收所述变更生效信息；
获取预先设定的所述变更生效信息；
从所述变更通知中获取的变更生效信息。
此处的预先设定可为通过通信协议预先设定的，或者，基站通过***消息预先设定的等方式进行预先设定的。
图样变更信息，直接指示了唤醒信号与唤醒时段之间的映射关系的变更。
使能变更信息，将指示终端使能或去使能唤醒信号的某一个唤醒信号的图样。
生效变更信息，可以携带在所述变更通知中下发，也可以利用额外的信息下发，还可以是不下发。总之所述生效变更信息是用于指示所述唤醒信号的配置变更的生效方式或者生效时间的。
在一些实施例中，所述步骤S220可包括：
当所述变更生效信息包含第一生效方式信息时，在接收到所述变更通知之后以第一延时生效方式生效所述唤醒信号的配置变更；
或者，
当所述变更生效信息包含第二生效方式信息时，在接收到所述变更通知之后以第二延时生效方式生效所述唤醒信号的配置变更；
或者，
当所述变更声响信息包含第三生效方式信息时，在接收到所述变更通知之后，立即生效所述唤醒信号的配置变更。
在终端侧生效所述唤醒信号的配置变更后，终端将根据变更后的唤醒信号的配置监听唤醒信号，并根据唤醒信号的监听结果，在唤醒信号的生效范围内保持休眠状态或唤醒状态。
此处的三种生效方式信息的相关描述可以参见前述实施例对应部分，此处就不再重复描述了。
在一些实施例中，所述步骤S220可包括：

在一些实施例中，所述步骤S220可包括：
若所述变更生效信息包含所述第一生效方式信息，以所述第一延时生效方式根据所述变更通知的下发时刻与变更前所述唤醒信号的图样，生效所述唤醒信号的配置变更。
在一些实施例中，所步骤S220可包括：
若所述变更生效信息包含所述第一生效方式信息时，根据所述第一 延时生效方式，若所述变更通知的下发时刻为变更前的所述唤醒信号的监听时刻，根据所述变更通知生效变更后所述唤醒信号的图样；
或者，

在一些实施例中，如图7所示，所述方法还包括：
步骤S200：在接收所述变更通知之前，接收所述唤醒信号的候选图样。
不同的候选图样，唤醒信号的频度不同，此处的频度即为唤醒信号与唤醒时段之间的映射关系。
在一些实施例中，所述步骤S200可包括：
接收所述唤醒信号的一套候选图样；
接收所述唤醒信号的多套候选图样，其中，在不同所述候选图样中，所述唤醒信号与唤醒时段的映射关系不同。
在一些实施例中，所述接收变更通知，包括：
接收通过MAC CE或者DCI下发的所述变更通知。
下发所述变更通知的消息可为各种消息，不局限于MAC CE和DCI，在本实施例中选用DCI和MAC CE；原因是MAC CE会触发一种DRX周期，例如，触发DRX的短周期，DRX周期还包括长周期，长周期的周期长度大于短周期的周期长度。
如此，MAC CE下发变更通知，同时触发DRX周期，该变更通知所指示的唤醒信号的配置变更的适用范围可为MAC CE下发所触发的DRX周期，但是具体实现时，变更通知所指示的唤醒信号的配置变更不 局限于MAC CE下发所触发的DRX周期。
DCI是一种物理层信令，物理层信令下发延时小，可以减少变更通知的下发延时，例如，通过DCI下发变更通知，可以适用于立即生效唤醒信号的配置变更场景。
在一些实施例中，所述方法还包括：
根据MAC CE携带的逻辑信道标识，确定出携带有所述变更通知的所述MAC CE。
MAC CE的头部会携带逻辑信道标识，该逻辑信道标识一方面指示MAC CE所映射的逻辑信道，同时会指示MAC CE所携带的消息内容，如此减少MAC CE的比特开销。
所述MAC CE携带有与所述变更通知对应的逻辑信道标识，如此，终端根据所述逻辑信道标识，可以确定出当前接收的MAC CE是否为携带有变更通知的MAC CE；或者，在接收到多个MAC CE时，确定出哪个MAC CE携带有唤醒信号的变更通知。
在一些实施例中，所述步骤S210可包括：
当所述唤醒信号的候选图样为一套时，接收利用所述MAC CE或者所述DCI下发的唤醒信号的使能变更通知；
或者，
当所述唤醒信号的候选图样为多套时，接收利用所述MAC CE或者所述DCI下发所述唤醒信号的多套所述候选图样中使能的所述候选图样。
针对候选图样的不同套数，所述MAC C或者所述DCI下发的变更通知下发的内容不同。
在一些实施例中，所述方法还包括：
基于所述DCI发送所述变更通知的反馈信息；
所述步骤S220可包括：
在发送指示确认收到所述变更通知的所述反馈信息之后，生效所述唤醒信号的配置变更。
终端接收到DCI之后需要发送反馈信息，该反馈信息包括但不限于ACK和NACK。整个DCI的ACK和NACK可以作为变更通知的反馈信息，也可以是利用专门的ACK和NACK仅对变更通知的接收成功与否进行反馈。
在发送确认收到变更通知的反馈信息之后，终端会生效所述唤醒信号的配置变更。
在发送否认收到变更通知的反馈信息之后，终端会根据重新接收的变更通知进行唤醒信号的配置变更生效。
在一些实施例中，所述方法还包括：
上报变更辅助信息，其中，所述变更辅助信息，用于确定所述变更通知。
该变更辅助信息包括但不限于终端建议的唤醒信号的图样、建议使能的唤醒信号的图样或者建议去使能的唤醒信号的图样，或者，可以用于确定当前所需生效的唤醒信号的图样的业务传输频繁度等信息。
总之，通过变更辅助信息的上报，可以使得基站在下发变更通知时，结合网络侧的需求和终端侧的需求，选择合适的配置进行变更通知的下发。

以下结合上述任意实施例提供几个具体示例：
示例1：
基站使用MAC CE或者DCI方式通知终端WUS的图样的配置变更。
WUS的图样，包含监听到一个唤醒信号跳过唤醒时段的频度，和/ 或生效所述配置变更的延时量。跳过所述唤醒时段说明：会触发所述终端在唤醒时段保持休眠状态而非唤醒状态。
作为一种实施方式，WUS跳过唤醒时段的频度可以是N为1；
作为一种实施方式，WUS跳过唤醒时段的频度可以是N为大于1的整数；
作为一种实施方式，WUS图样的变更可以是enable某个WUS的图样；
作为一种实施例，WUS图样的变更可以是去使能某个WUS的图样；
即WUS的监听的图样不生效，即根据原来DRX周期内唤醒时段和休眠时段，终端对应的在唤醒状态和休眠状态之间切换。
图10为一种WUS的图样变更示意图，WUS的图样包含的映射关系从1：L、变更为1：N、变更为1：1，最后映射关系为1：1的WUS的图样被去使能。
在一些实施方式中，基站先显式方式指示终端WUS的候选参数集；所述WUS的候选参数集，即对应于前述的WUS的候选图样。
作为一种实施方式，基站用RRC配置中携带WUS的候选参数集：
作为一种实施方式，可以携带WUS的一套配置，该配置中WUS跳过唤醒时段的频度可能是1或者N；
作为一种实施方式，也可以携带WUS的多套配置，如WUS跳过唤醒时段的频度可能是1或者其他不同频度；
基站利用MAC CE下发，用于WUS的图样的变更；
作为一种实施方式，MAC CE为新引入，即需要引入新的逻辑信道ID来表明这是一个用于WUS的图样变更的MAC CE；
作为一种实施方式，MAC CE中可以有不同的指示位指明使用不同的WUS的图样的变更；
作为一种实施方式，若有一套WUS的配置，则MAC CE携带字段为使能该套配置和去使能该套配置，具体体现为1个比特，分别用“0”，“1”表示；此处一套WUS的配置对应于前述一套WUS的备选图样。
作为一种实施例，若有多套配置，则可以为多个字段，体现具体是哪套配置，比如2个比特来体现两套配置，2个比特的比特值为“0”为失效，2个比特的比特值为“1”为生效第一套配置，2个比特的比特值为“2”为生效第二套配置，2个比特的比特值为“3”为保留字段等。
作为一种实施方式，MAC CE中也可以具体指明目标WUS的图样的相关参数；
在一些实施方式中，基站利用DCI形式下发，用于具体的WUS的图样的变更。
在一些实施方式中，基站使用DCI通知终端WUS图样的变更，需要收到终端的ACK才认为终端已经正常接收到。
在一些实施方式中，终端若原有工作模式为使用WUS，则在收到基站指示之后的行为有两种方式：立即生效和延迟到下一个WUS时刻生效：
终端在收到基站指示解码成功之后，若正好遇到当前WUS的生效时刻没有结束，可以等到该WUS的生效时刻结束之后再启用新的配置。
例如，若原来WUS的图样中映射关系为1：N生效，则等到WUS检测之后生效的N个唤醒时段后才启用新的配置，如中蓝线所示，若目标工作模式依然为WUS工作模式，即下一个新的WUS信号检测结果按照新的配置生效。
在一些实施例方式中，终端在收到基站指示解码成功之后，即便遇到当前WUS的生效时刻，也进行立即生效。即已经检测到的WUS信号检测结果按照新的配置生效。
在一些实施例中，生效方式可以基于用显示信令(RRC消息、***消息)通知终端，或者基于协议约定。
从WUS的图样中映射关系从1：S变更为1：1方式，采用延迟生效，否则若按照立即生效方式，若WUS被检测到后则意味着在终端检测到一个WUS之后，之后的S个唤醒时段都是需要启动的，此时网络不会发送WUS。但是终端马上按照1：1监听，则会不启动唤醒时段，就会错过，造成丢包。
去使能WUS的图样中映射关系从1：S，采用延迟生效为佳，若按照立即生效方式，不会丢包，但是会造成额外的耗电，因为若是若没有监听到WUS就跳个N个，但是去使能方式下则造成额外的监听，造成耗电。
去使能WUS的图样中映射关系，也可以采用延迟生效方式；
从WUS的图样中映射关系从1:1变更为1:S，最好采用延迟生效方式。
在一些实施方式中，基站使用MAC CE或者DCI方式通知终端WUS的图样的变更可以基于终端提供的辅助信息上报，比如终端指明期望的WUS的图样的变更：
作为一种实施例，终端可以指明期望的WUS跳过唤醒时段的频度；
作为一种实施例，终端可以指明当前WUS去使能。
作为一种实施例，终端可以指明某套WUS使能。
