具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种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。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样所限定的并非一定不同。
需要说明的是，本公开中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本公开实施例中，“指示”可以包括直接指示和间接指示。例如，以下文中第一控制信息为例，第一控制信息可以直接携带信息A的本身或者其索引，以实现直接指示信息A的目的。或者，第一控制信息也可以携带与信息A存在关联关系的信息B，从而在指示信息B的同时实现间接指示信息A的目的。
本公开实施例提供的技术方案可以应用于各种通信系统，例如，采用5G(5th generation)通信技术的新空口(New Radio，NR)通信系统，未来演进系统或者多种通信融合系统等。
示例性地，图1中示出了本公开实施例提供的一种通信系统的结构示意图。该通信系统可以包括基站以及多个终端(例如图1中所示的终端1、终端2)，基站可以与该一个或多个终端通信连接。
基站可以用于实现终端的资源调度、无线资源管理、无线接入控制等功能。基站可以是小型基站、无线接入点、收发点(transmission reception point，TRP)、传输点(transmission point，TP)以及某种其它接入节点中的任一节点。
终端可以为终端设备，或者具有终端的功能的设备。终端也可以称为用户设备(user equipment，UE)、移动台、移动终端等。终端可以是手机、平板电脑、带无线收发功能的电脑、虚拟现实终端、增强现实终端、工业控制中的无线终端、无人驾驶中的无线终端、远程手术中的无线终端、运输安全中的无线终端、智慧城市中的无线终端、智慧家庭中的无线终端等等。本公开的实施例对终端所采用的具体设备形态不做限定。
在一些实施例中，终端可以设置有第一接收机和第二接收机。可选地，处于开启状态的第一接收机的功耗远小于处于开启状态的第二接收机的功耗。第一接收机可以有其他名称，例如唤醒电路、低功耗小电路、唤醒模块等，第二接收机可以有其他名称，例如主接收电路、主接收模块、主接收单元等，对此不作限定。在本公开实施例中，第一接收机主要用于支持终端接收与唤醒相关的信号。第二接收机用于接收数据和/或传输数据。
在一些实施例中，终端只开启第一接收机，通过第一接收机接收到唤醒自身的唤醒信号之后，再开启第二接收机。若终端未接收到唤醒信号， 终端不开启第二接收机(此时，终端的状态可以称为唤醒态、LP-WUS状态、LP-WUS检测状态、也可以命名为其他名称)。如此，可以降低终端的功率消耗。
需要说明的是，图1仅为示例性框架图，图1中包括的设备的数量、各个设备的名称不受限制，且除图1所示的设备外，通信系统还可以包括其他设备，如核心网设备。
本公开的实施例的应用场景不做限定。本公开实施例描述的系统架构以及业务场景是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开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，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
如图2所示，本公开实施例提供一种唤醒信号的传输方法，该方法包括以下步骤(S101-S104)。
S101、基站生成唤醒信号。
唤醒信号是用于唤醒处于休眠状态的终端的信号。例如，在系统消息发生变更时，基站可以生成并发送唤醒信号，以唤醒各个终端来接收变更后的系统消息。又例如，在某个终端(以终端A为例)的数据到达基站后，基站可以生成并发送唤醒信号，以唤醒终端A进入连接态进行接收数据。又例如，当终端收发完数据，且进入休眠状态后，终端就关闭第二接收机，只开启第一接收机处在低功耗模式下；或者经过一定时长的测量后满足第二接收机关闭条件的情况下，关闭第二接收机，只开启第一接收处在低功耗模式下。
可选地，本公开实施例中的唤醒信号可以有其他名称，例如唤醒单元、唤醒帧等，对此不作限定。
在一些实施例中，唤醒信号包括唤醒前导码。唤醒前导码可以用于辅助终端的接收机进行时间和频率的同步。可选地，唤醒前导码所采用的比特序列可以是标准中定义的；或者，唤醒前导码所采用的比特序列也可以是基站确定的；又或者，唤醒前导码所采用的比特序列也可以是基站与终端协商确定的。唤醒前导码除了辅助终端进行时间和频率的同步外，还可以携带唤醒数据的相关指示信息。
在一些实施例中，唤醒信号除了包括唤醒前导码之外，还可以包括唤醒数据。示例性的，如图3所示，在唤醒信号中，唤醒前导码在唤醒数据之前映射，从而终端在接收到唤醒前导码之后可以准备接收唤醒数据。应 理解，在图3所示的唤醒信号的结构中，唤醒前导码可以用于指示唤醒数据的起始位置。
在一些实施例中，唤醒数据包括以下信息中的至少一项：短信息、终端索引、组索引、小区索引或者数据内容指示。
以下对唤醒数据承载的信息进行介绍。
(1)短信息
短信息包括以下类型中的至少一项：系统消息变更指示、预警信息指示或者停止检测指示。系统消息变更指示用于指示系统消息发生变更。预警信息指示用于指示接收预警信息。停止检测指示用于指示(在非授权频谱上)停止检测唤醒信号。
示例性的，该预警信息可以为自然灾害或紧急事件的预警信息，例如可以是地震海啸预警系统(earthquake and tsunami warning system，ETWS)的信息，或者公共预警系统(commercial mobile alert system，CMAS)的信息。
作为一种可能的实现方式，唤醒数据可以包括以下至少一项：系统消息变更指示对应的指示位，预警信息指示对应的指示位以及停止检测指示对应的指示位。
系统消息变更指示对应的指示位可以以一个比特来实现，该比特的取值为0，表征唤醒数据未携带系统消息变更指示；该比特的取值为1，表征唤醒数据携带系统消息变更指示。

作为另一种可能的实现方式，唤醒数据可以包括短信息对应的指示位。该短信息对应的指示位可以采用多个比特来实现。以该短信息对应的指示位以2个比特来实现为例，该短信息对应的指示位的取值为00，为保留值；该短信息对应的指示位的取值为01，表示唤醒数据携带系统消息变更指示；该短信息对应的指示位的取值为10，表示唤醒数据携带预警信息指示；该短信息对应的指示位的取值为11，表示唤醒数据携带停止检测指示。
(2)终端索引

所述RNTI包括以下任意一项：唤醒专有的RNTI、UE专有的RNTI、UE专有的用于唤醒的RNTI、UE专有的用于空闲状态的RNTI、UE专有的用于在最近连接小区空闲态使用的RNTI、UE专有的用于在最近连接小区唤醒使用的RNTI、或者非激活RNTI。
可选地，5G-S-TMSI和5G-TMSI可以是移动管理网元为终端配置的。RNTI可以是基站为终端配置的。唤醒标识可以是核心网为终端设备配置的。应理解，上述各种类型的终端索引的配置方式仅是示例性的，本公开实施例不限于此。
在一些实施例中，在唤醒数据包括N个终端索引的情况下，N个终端索引可以按照预设规则进行排列。例如，N个终端索引按照索引值从大到小的顺序排列，或者按照索引值从小到大的顺序进行排列。
(3)组索引
组索引用于标识一个小组，一个小组可以包括一个或多个终端设备。在一些实施例中，小组的分组类型可以包括以下一项或者多项：基于核心网(Core Network，CN)的分组、基于预设终端索引的分组、或者基于CN和预设终端索引的分组。预设终端索引可以是基站配置的，也可以是基站与终端设备协商出来的，也可以是根据终端索引计算得到的。
(4)小区索引
小区索引用于标识小区。本公开实施例中的小区可以是宏小区、微小区、室内小区等，对此不作限定。在一些实施例中，小区索引包括基站标识的全部或者部分比特，或者物理层小区标识(Physical Cell Id，PCI)的全部或部分比特。
(5)数据内容指示
在一些实施例中，数据内容指示包括以下类型中的至少一项：数据传输格式指示、数据类型指示、数据长度指示、终端索引数量指示、组索引对应的分组类型指示、数据重复次数指示、数据码率指示、数据调制方式指示、或者数据传输速率指示。

数据传输速率指示用于指示唤醒数据的传输速率。
以上是对唤醒数据携带的信息的介绍，应理解唤醒数据除了携带短信息、终端索引、组索引以及小区索引之外还可以携带其他类型的信息，本公开实施例对此不作限定。
在一些实施例中，唤醒数据中的信息可以按照优先级进行映射。
示例性的，优先级从高到底的顺序可以为：短信息、小区索引、组索引、终端索引。
示例性的，优先级从高到低的顺序为：所述短信息，所述组索引。
示例性的，优先级从高到低的顺序为：所述短信息，所述终端索引。
示例性的，优先级从高到低的顺序为：所述短信息，所述组索引，所述终端索引。
示例性的，所述优先级从高到低的顺序为：所述数据内容指示，所述短信息，所述组索引，所述终端索引。
示例性的，所述优先级从高到低的顺序为：所述数据内容指示、所述短信息、所述终端索引。
示例性的，所述优先级从高到低的顺序为：所述数据内容指示、所述终端索引。
示例性的，所述优先级从高到低的顺序为所述数据内容指示、所述短信息、所述小区索引、所述组索引、所述终端索引。
在一些实施例中，唤醒数据还包括以下至少之一：间隔标识，结束标识，子前导码，或者校验码。子前导码用于辅助终端对唤醒数据进行同步。间隔标识用于间隔唤醒数据中不同部分的内容。结束标识用于指示唤醒数据的结束位置，或者唤醒数据中特定内容的结束位置。校验码用于对唤醒数据进行校验。
在一些实施例中，如图4所示，在唤醒数据包括N个终端索引的情况下，唤醒数据中每隔K个终端索引存在间隔标识、结束标识、校验码中的至少一种，N大于或等于K，N和K均为正整数。K的取值可以预先确定，也可以根据N的取值来确定。可选地，标识的长度可以固定为Y个比特。这样，通过标识来分割多个终端索引，从而即使标识前的K个终端索引因为干扰等因素而出现比特缺少等问题，也不会影响终端设备对标识之后的终端索引的解析。这样，在唤醒数据携带多个终端索引的情况下，能够保证终端设备对唤醒数据中的终端索引的解析成功率，从而减少误唤醒带来的功耗增加。
在一些实施例中，在唤醒数据的长度受到限制的情况下，基站可以根据各种类型的信息的优先级以及各种类型的信息的长度，确定唤醒数据中承载的信息。
例如，唤醒数据的长度为M个比特，终端索引的长度为X个比特，则在唤醒数据需要携带终端索引的情况下，唤醒数据中最多承载floor(M/X)个终端索引。floor()表示向下取整。
又例如，唤醒数据的长度为M个比特，终端索引的长度为X个比特，预设标识的长度为Y个比特，预设标识的个数为y，则在唤醒数据需要携带终端索引和预设标识的情况下，唤醒数据中承载floor(M/(X+Y*y))个终端索引。其中，预设标识为间隔标识。
又例如，唤醒数据的长度为M个比特，终端索引的长度为X个比特，预设标识的长度为Y个比特，预设标识的个数为y，短信息的长度为3个比特。在需要发送短信息和终端索引的情况下，由于短信息的优先级高于终端索引，所以唤醒数据在携带短信息的基础上最多再携带floor((M-3)/(X+Y*y))个终端索引。
又例如，唤醒数据的长度为M个比特，终端索引的长度为X个比特，短信息的长度为3个比特，小区索引的长度为6个比特。假设需要发送的信息有短信息、小区索引和K个终端索引，则由于短信息和小区索引的优先级均高于终端索引的优先级，因此唤醒数据最多携带K1＝floor((M-9)/(X))个终端索引。这样，在K1大于或等于K的情况下，该唤醒数据包括短信息、小区索引以及K个终端索引。在K1小于K的情况下，该唤醒数据包括短信息、小区索引以及K1个终端索引，该K1个终端索引是从上述K个终端索引中选择出来的。例如，该K1个终端索引可以是K个终端索引中、在索引值由大到小排列的情况下前K1个索引值对应的前K1个终端索 引；或者，该K1个终端索引可以是K个终端索引中、在索引值由小到大排列的情况下前K1个索引值对应的前K1个终端索引；又或者，该K1个终端索引是从K个终端索引中随机选择出来的。
可选地，可以采用显式或者隐式的方式来指示唤醒数据中承载的信息。这样，一方面，终端设备可以在接收到唤醒数据前知道唤醒数据中承载的信息的类型、数量等，从而为正确解析唤醒数据做好准备，以保证对唤醒数据的解析成功率。另一方面，唤醒数据可以根据实际需求增加或者减少用于承载信息的比特，从而有利于节约唤醒数据的传输开销。
在一些实施例中，隐式指示的方式可以实现为：唤醒前导码的长度和/或比特序列用于指示唤醒数据承载的信息。例如，可以预先规定：与唤醒前导码的长度为第一长度对应的唤醒数据中携带短信息；与唤醒前导码的长度为第二长度对应的唤醒数据中携带终端索引；与唤醒前导码的长度为第三长度对应的唤醒数据中携带组索引；与唤醒前导码的长度为第四长度对应的唤醒数据中携带小区索引。又例如，可以预先规定：与唤醒前导码采用的第一比特序列对应的唤醒数据中携带短信息；与唤醒前导码采用的第二比特序列对应的唤醒数据中携带终端索引；与唤醒前导码采用的第三比特序列对应的唤醒数据中携带组索引；与唤醒前导码采用的第四比特序列对应的唤醒数据中携带小区索引。应理解，上述示例不构成唤醒数据承载的信息与唤醒前导码的长度和/或比特序列之间对应关系的限定。
在一些实施例中，显式指示的方式可以实现为：唤醒信号还包括第一唤醒指示信息，该第一唤醒指示信息用于指示唤醒数据承载的信息。如图5所示，在唤醒信号中，第一唤醒指示信息可以在唤醒前导码之后映射，且在唤醒数据之前映射。应理解，在图5所示的唤醒信号的结构中，唤醒前导码可以用于指示第一唤醒指示信息的起始位置。可选地，第一唤醒指示信息的比特数目是固定的。这样，终端设备在从唤醒信号中解析出唤醒前导码之后，自然可以获知第一唤醒指示信息和唤醒数据的起始位置。应理解的是，第一唤醒指示信息的比特数目可以是基站配置的，也可以是标准中规定的。
作为一种可能的实现方式，第一唤醒指示信息包括第一指示信息、第二指示信息、第三指示信息、第四指示信息、第五指示信息、第六指示信息或者第七指示信息中的至少一项。
第一指示信息用于指示唤醒数据是否携带短信息。第一指示信息也可以称为短信息指示位。示例性的，第一指示信息可以用一个比特来实现。 例如，该比特的取值为0，用于指示唤醒数据未携带短信息；该比特的取值为1，用于指示唤醒数据携带短信息。
第二指示信息用于指示唤醒数据是否携带终端索引。第二指示信息也可以称为终端索引指示位。示例性的，第二指示信息可以用一个比特来实现。例如，该比特的取值为0，用于指示唤醒数据未携带终端索引；该比特的取值为1，用于指示唤醒数据携带终端索引。
第三指示信息用于指示唤醒数据是否携带组索引。第三指示信息也可以称为组索引指示位。示例性的，第三指示信息可以用一个比特来实现。例如，该比特的取值为0，用于指示唤醒数据未携带组索引；该比特的取值为1，用于指示唤醒数据携带组索引。
第四指示信息用于指示唤醒数据是否携带小区索引。第四指示信息也可以称为小区索引指示位。示例性的，第四指示信息可以用一个比特来实现。例如，该比特的取值为0，用于指示唤醒数据未携带小区索引；该比特的取值为1，用于指示唤醒数据携带小区索引。
第五指示信息用于指示唤醒数据携带的短信息的类型。第五指示信息也可以称为短信息类型指示位。第五指示信息的长度与短信息的类型的最大数目相关。
第六指示信息用于指示唤醒数据中携带的终端索引的数目。第六指示信息也可以称为终端索引个数指示位。第六指示信息的长度与唤醒数据中承载的终端索引的最大数目相关。可选地，唤醒数据中承载的终端索引的最大数目可以预先设定。示例性的，唤醒数据中承载的终端索引的最大数目为7，第六指示信息的长度即为3个比特。
第七指示信息用于指示唤醒数据中携带的组索引对应的分组类型。第七指示信息的长度和分组类型的数目相关，例如，分组类型的数目为3，第七指示信息的长度为2个比特。示例性的，表1示出第七指示信息的取值与分组类型之间的对应关系。
表1

作为另一种可能的实现方式，第一唤醒指示信息包括第八指示信息，第八指示信息的取值与唤醒数据的信息组合存在对应关系，信息组合包括短信息、终端索引、组索引或者小区索引中的至少一项。示例性的，表2示出信息组合的可能实现方式。
表2

作为一个示例，表3示出第八指示信息的取值与唤醒数据的信息组合之间的一种对应关系。
表3

作为另一个示例，表4示出第八指示信息的取值与唤醒数据的信息组合之间的另一种对应关系。
表4
在一些实施例中，在唤醒数据中，数据内容指示和短信息可以联合指示。基于此，作为另一个示例，表5示出第八指示信息的取值与唤醒数据的信息组合之间的另一种对应关系。
表5
作为又一种可能的实现方式，第一唤醒指示信息包括第九指示信息。第九指示信息的取值与唤醒数据的传输格式存在对应关系，唤醒数据的传 输格式包含唤醒数据的传输速率、码率、长度、重复次数、调制方式或者内容中的至少一项。示例性的，表6示出第九指示信息的取值与唤醒数据的传输格式的对应关系。G和H均为正整数。
表6
在一些实施例中，唤醒信号还可以包括第二唤醒指示信息。第二唤醒指示信息用于指示唤醒数据的结束位置。示例性的，如图6(a)或图6(b)所示，在唤醒信号中，第二唤醒指示信息在唤醒数据之后映射。应理解，第二唤醒指示信息可以以预设的比特序列来实现，终端设备从唤醒信号中解析出该预设的比特序列之后，即可以获知已接收完唤醒信号中的唤醒数据。这样，终端设备基于唤醒信号中唤醒数据的起始位置和结束位置，可以确定唤醒数据的长度；基于唤醒数据的长度以及唤醒数据中各个类型的信息的长度，即可以正确解析唤醒数据。
在一些实施例中，唤醒信号还可以包括第三唤醒指示信息。第三唤醒指示信息用于对唤醒数据进行校验。第三唤醒指示信息是基于预设的校验算法和唤醒数据生成的。示例性的，如图7(a)或图7(b)所示，在唤醒信号中，第三唤醒指示信息在唤醒数据之后映射。应理解，在基于第三唤醒指示信息对唤醒数据进行校验确定唤醒数据不正确的情况下，终端设备可以忽略该唤醒信号，也即终端设备不根据唤醒数据中的相关信息来打开第二接收机。
S102、基站发送唤醒信号。
作为一种可能的实现方式，基站以二进制启闭键控(On-Off Keying，OOK)调制方式发送唤醒信号。应理解的是，采用OOK调制方式可以降低接收机的实现复杂度，有利于降低接收机的成本。不排除其他低功耗， 低成本的调制方式。
S103、终端设备通过第一接收机接收唤醒信号。
在一些实施例中，终端设备可以根据信息的优先级确定唤醒数据中的信息。优先级的相关介绍可以参考前文，在此不再赘述。
在一些实施例中，在唤醒信号包括第一唤醒指示信息的情况下，终端设备可以通过第一唤醒指示信息确定唤醒数据承载的信息。
可选地，在第一唤醒指示信息包括第一指示信息的情况下，终端设备通过所述第一指示信息确定所述唤醒数据是否携带所述短信息。
可选地，在第一唤醒指示信息包括第二指示信息的情况下，终端设备通过所述第二指示信息确定所述唤醒数据是否携带所述终端索引。
可选地，在第一唤醒指示信息包括第三指示信息的情况下，终端设备通过所述第三指示信息确定所述唤醒数据是否携带所述组索引。
可选地，在第一唤醒指示信息包括第四指示信息的情况下，终端设备通过所述第四指示信息确定所述唤醒数据是否携带所述小区索引。
可选地，在第一唤醒指示信息包括第五指示信息的情况下，终端设备通过所述第五指示信息确定所述唤醒数据携带的短信息的类型。
可选地，在第一唤醒指示信息包括第六指示信息的情况下，终端设备通过所述第六指示信息确定所述唤醒数据中携带的终端索引的数目。
可选地，在第一唤醒指示信息包括第七指示信息的情况下，终端设备通过所述第七指示信息确定所述唤醒数据中携带的组索引对应的分组类型。
可选地，在第一唤醒指示信息包括第八指示信息的情况下，终端设备通过所述第八指示信息的取值和第八指示信息与所述唤醒数据的信息组合的对应关系确定唤醒数据的信息组合。
可选地，在第一唤醒指示信息包括第九指示信息的情况下，终端设备通过所述第九指示信息的取值和第九指示信息与所述唤醒数据的传输格式的对应关系确定唤醒数据的传输格式。
在一些实施例中，在唤醒信号包括第二唤醒指示信息的情况下，终端设备可以通过所述第二唤醒指示信息确定所述唤醒数据的结束位置。
在一些实施例中，在唤醒信号包括第三唤醒指示信息的情况下，终端设备通过所述第三唤醒指示信息对所述唤醒数据进行校验。
在一些实施例中，在唤醒数据包括数据内容指示的情况下，终端设备可以通过所述数据内容指示确定唤醒数据相关的信息。
S104、终端设备根据唤醒信号，确定第二接收机的工作方式。
作为一种可能的实现方式，在唤醒数据中承载终端设备自身的终端索引、终端设备所接入小区的小区索引、终端设备所属小组的组索引、系统消息变更指示、或者预警信息指示中的至少一项的情况下，终端设备控制第二接收机开机工作。
举例来说，终端设备接收到图8所示的唤醒信号，通过解析唤醒信号的第一唤醒指示信息，可以获知在第一唤醒指示信息中短信息指示位的取值为1，其他指示位的取值为0，从而可以确定唤醒数据中仅携带短信息。在唤醒数据仅携带短信息的情况下，终端设备可以根据基于预先配置(例如标准中的规定)，确定唤醒数据中第一个比特为系统消息变更指示对应的指示位，第二个比特为预警信息指示对应的指示位。由于唤醒数据中第一个比特的取值为0，第二个比特的取值为1，因此，终端设备可以确定唤醒数据携带预警信息指示，终端设备打开第二接收机以接收预警信息。
举例来说，终端设备接收到图9所示的唤醒信号，通过解析唤醒信号的第一唤醒指示信息，可以获知在第一唤醒指示信息中终端索引指示位的取值为1，其他指示位的取值为0，从而可以确定唤醒数据中仅携带终端索引。进而，终端设备通过解析唤醒数据，能够获知唤醒数据中携带的终端索引为000000000000001。若终端设备自身的终端索引为000000000000001，则终端设备会打开第二接收机以进行相应数据的接收。若终端设备自身的索引不为000000000000001，则终端设备会保持第二接收机处于关闭状态。
举例来说，终端设备接收到图10所示的唤醒信号，通过解析唤醒信号的第一唤醒指示信息，可以获知在第一唤醒指示信息中终端索引指示位的取值为1，终端索引个数指示位的取值为011，从而可以确定唤醒数据中携带3个终端索引。假设一个终端索引的长度为4个比特，终端设备通过解析唤醒数据能够确定3个终端索引分别为0111，0001，0101。进而，终端设备可以根据自身的终端索引是否是上述3个终端索引中的一个，来确定是否打开第二接收机。
举例来说，终端设备接收到图11所示的唤醒信号，通过解析唤醒信号的第一唤醒指示信息，可以获知在第一唤醒指示信息中组索引指示位的取值为1，分组类型指示位的取值为01，从而可以确定唤醒数据中携带基于CN分组的组索引。假设基于CN分组的总的组数为4，唤醒数据中可以为每个组索引设置对应的指示位。这样，终端设备通过解析唤醒数据，可以 确定唤醒数据中第4个组索引的指示位的取值为1，可以确定基站是在唤醒第4个小组中的终端设备。
本公开实施例中，唤醒信号除了包括唤醒前导码之外还包括唤醒数据。从而终端设备可以基于唤醒信号中的唤醒数据确定是否需要打开第二接收机，而不是一直打开第二接收机。这样，终端设备的第二接收机长时间处于关闭状态，而仅在需要的时候处于开启状态，从而满足终端设备的低功耗需求。
可以理解的是，通信装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本公开的范围。
