下面对本申请实施例涉及的相关名词进行说明如下。
一、低功耗接收机
低功耗接收机，即低功耗唤醒接收机(low power wake up radio，LP-WUR)。LP-WUR的基本工作原理为接收端包含第一模块和第二模块，具体如图2a所示，第一模块为主通信模块，用于移动通信数据的收发，第二模块为低功耗接收模块(也称低功耗唤醒接收模块)，用于接收上述唤醒信号。终端在节能状态下开启低功耗接收模块来监听LP-WUS且关闭主通信模块。当有下行数据到达时，网络会发送唤醒信号给终端，终端通过低功耗接收模块监听到唤醒信号后通过一系列的判断后触发主通信模块从关闭到开启，而此时低功耗接收模块从工作态进入关闭状态。低功耗唤醒接收模块可以连续开启，或间歇性开启， 在开启时可接收低功耗唤醒信号。
二、低功耗唤醒信号
为了减少终端在待机状态下的接收活动，使得射频(Radio Frequency，RF)和基带(MODEM)模块真正的关闭从而大大降低通信接收的功耗，可以通过在终端的接收模块中引入了一个近“零”功率的接收机从而实现。这个近“零”功率的接收机不需要复杂的RF模块的信号检测(如放大、滤波、量化等等)和MODEM的信号处理，只靠被动的匹配滤波和较小功耗的信号处理。
在基站侧，通过按需(on-demand)触发唤醒信号，就可以激活近“零”功率的接收机获知激活的通告，从而触发终端内部的一系列流程，例如，打开射频收发以及基带处理等模块。
这种唤醒信号通常来说是一些比较简单的开关键控信号(on-off keying)，开关键控信号的时域样式如图2b所示，那样接收机就可以通过简单的能量检测，以及之后的可能的序列检测识别等过程获知唤醒通告。此外，在终端开启低功耗唤醒接收机来接收唤醒信号的同时，主接收机模块可以维持在一个较低耗电水平下工作，从而通过接收唤醒信号来实现功耗节省。
三、信标(beacon)信号
beacon信号是一种周期性发送的用来传递时间信息的信号。接收端可以通过接收beacon信号来获取时间同步信息。一些实施例中，还可以通过接收beacon信号来进行移动性测量或信道测量等。
一种实现中，beacon信号采用特定的媒体接入控制(MAC)帧(frame)进行传输，其结构如图2c所示。WUR beacon MAC frame的类型相关控制(Type dependent control)携带AP的TSF时钟64bit中的第5到第16bit的信息，用户收到对应信息比特后，根据802.11ba定义的时间更新准则，更新用户本地的TSF时钟，从而达到与AP同步的目的。WUR beacon的发送周期和发送起始位置的偏移量由AP发送的操作元素(operation element)指示，周期为两次beacon发送间最少的TSF时间单元数，起始位置为相对于TSF0偏移的TSF时间单元数。当发生载波监听多路访问(CSMA)延期(deferrals)，WUR beacon在当前周期会延迟发送，但在后续周期仍按WUR beacon的发送周期和发送起始位置确定的位置发送。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的同步信息的获取方案进行详细地说明。

为了进一步理解本申请实施例所提供的技术方案，下面以第一信号为信标信号为例进行说明。
实施例一
在该实施例中，以OOK符号为时间单位，基于第一配置信息和第二指示信息(即信标信号监听机会的索引信息)获取时间同步信息。
在该实施例中，网络侧设备配置或协议约定信标信号监听集，所述信标信号监听集包括至少一个信标信号监听机会。信标信号监听机会的编号为一个信标信号监听集内该信标信号监听机会的编号。例如，在图6中，一个信标信号集合包括M＝8个信标信号，每个信标信号的监听机会的编号从0到7。需要说明的是，如果一个信标信号监听集仅包含一个信标信号监听机会，则不需要信标信号监听机会的编号信息。
网络侧设备配置或协议约定第一配置信息包括：
(1)时间单元配置信息，其中，时间单元配置信息可以包括OOK符号单元的划分信息、OOK符号的编号周期等信息。OOK符号的编号周期可以等于信标信号周期长度。也就是，在一个信标信号周期内进行OOK符号的编号。
(2)信标信号配置信息，其中，信标信号配置可以包括以下信息：
a)信标信号监听集所包含的信标信号监听机会的个数信息，M＝8；
b)信标信号监听集的时域图案配置，该配置信息具体可以包含如下至少一项：
i.信标信号监听集中的信标信号所在OOK符号的信息。
ii.相邻信标信号监听机会的时间间隔信息，例如是2个OOK符号长度。

(3)唤醒信号配置信息，其中，唤醒信号配置信息可以包括：唤醒信号的监听机会配置信息。该监听机会配置信息指的是时域位置信息。
需要说明的是，每一个信标信号的起始位置与OOK符号的起始位置是对齐的。根据信标信号监听集的时域图案配置，网络侧设备跟终端可以获知一个信标信号监听集内的所有信标信号所在OOK符号索引/信息，如图7所示。
此外，信标信号还可以承载第一指示信息，第一指示信息包括：信标信号监听机会的索引信息。
在本申请实施例中，终端检测到的每个信标信号中携带其对应的信标信号监听机会的索引信息。终端在一个信标信号周期内根据终端实现可以在一个信标信号监听集包含的信标信号监听机会中检测到的一个或多个信标信号。终端实现指的是终端根据检测到的信标信号强度大小，能够检测到最优K个的信标信号，例如，图7中终端接收到了信标信号2和3。
终端根据检测到的信标信号监听机会索引以及约定好的信标信号监听集的时域图案能够确定检测到的信标信号所在的OOK符号索引以及边界位置。例如，在图7中，终端在检测到信标信号2和3之后，能够确定OOK符号的边界以及OOK符号的索引等信息。此外，终端也能根据信标信号监听集的时域图案以及第一偏移量确定，终端所处时间位置距离当前所在信标信号监听周期起始位置的距离等。在此不再一一赘述。由此，终端可以实现下行OOK符号同步，继而纠正时域偏移。此外，根据确定的OOK符号边界以及OOK符号索引信息，再结合唤醒信号监听时机的所占的OOK符号索引配置信息，所述终端能够确定所述唤醒信号的监听机会的起始OOK符号位置，继而在唤醒信号的监听机会上检测唤醒信号。
实施例二
本实施例中，以OOK符号为时间单位，基于第二指示信息(OOK索引信息)获取同步时间信息。
在该实施例中，网络侧设备配置或协议约定一个信标信号监听集内仅包含一个信标信号监听机会，因此不需要提供信标信号监听机会索引信息。该信标信号监听机会占用10 个OOK符号长度。该信标信号的起始位置与OOK符号的起始位置是对齐的。
网络侧设备配置或协议约定第一配置信息包括：
(1)时间单元配置信息，该时间单元配置信息可以包括OOK符号单元的划分信息、OOK符号的编号周期等信息。OOK符号的编号周期可以等于信标信号周期长度。也就是，在一个信标信号周期内进行OOK符号的编号。
(2)唤醒信号配置信息，该唤醒信号配置信息可以包括：唤醒信号的监听机会配置信息；该监听机会配置信息指的是时域位置信息。
信标信号中承载的第一指示信息，第一指示信息包括：OOK(即第一时间单元)索引信息。需要说明的是，OOK索引为在一个信标信号周期内的OOK索引。
根据时间单元配置信息以及检测到的信标信号，终端能够确定OOK的符号边界，从而纠正不超过一个OOK符号长度的时间偏移。此外，根据该信标信号承载的OOK索引能够确定距离当前所在信标信号监听周期起始位置的偏移量等。终端根据确定的OOK符号边界以及检测到的OOK信标信号的OOK符号索引，再结合唤醒信号监听机会所关联的OOK符号索引，能够找到所述唤醒信号的监听机会的起始OOK符号位置，继而在唤醒信号的监听机会上检测唤醒信号。
可选地，唤醒信号的监听机会配置信息中，唤醒信号的监听机会可以相对于信标信号监听周期的起始位置进行配置。例如，配置一个距离信标信号监听周期起始位置的时间偏移量来确定唤醒信号的监听机会。此外，唤醒信号的监听机会可以相对于信标信号监听持续时间的结束位置进行配置，例如配置一个距离信标信号监听持续时间的结束位置的时间偏移量来确定唤醒信号的监听机会。
实施例三
在本实施例中，基于第一配置信息和第二指示信息获取时间同步信息。
网络侧设备配置或协议约定信标信号集，所述信标信号监听集包括至少一个信标信号监听机会。一个信标信号监听周期内，网络侧设备按照信标信号监听集发送一个信标信号集合。信标信号的编号为一个信标信号集合内该信标信号的编号。例如，图6中，一个信标信号集合包括M＝8个信标信号，每个信标信号的监听机会的编号从0到7。需要说明的是，如果一个信标信号监听集仅包含一个信标信号监听机会，则不需要信标信号监听机会的编号信息。
网络侧设备配置或协议约定第一配置信息包括：
(1)时间单元配置信息，该时间单元信息可以包括OOK符号单元的划分信息、OOK符号的编号周期等信息。OOK符号的编号周期可以等于信标信号周期长度。也就是，在 一个信标信号周期内进行OOK符号的编号。
(2)信标信号配置信息，该信标信号配置信息可以包括：信标信号监听集所包含的信标信号监听机会的个数信息，M＝8；以及信标信号监听集的时域图案配置。
其中，信标信号监听集的时域图案配具体可以包含如下至少一项：
a)信标信号监听集中的信标信号所在slot和符号(第二时间单元)的信息。第二时间单元包括两类时间单元：slot和符号。
b)相邻信标信号监听机会的时间间隔信息，例如是在一个slot内的4个信标信号监听机会之间的间隔为2个符号长度，不同slot内的相邻信标信号监听机会之间的间隔为1个slot。
c)第一偏移量信息，所述第一偏移量为信标信号监听集的起始位置距离其所在信标信号监听周期的起始位置的偏移量；例如，4个slot长度。
d)每个信标信号所占的时间长度信息，例如每个信标信号占2个符号长度。
(3)唤醒信号配置信息，该唤醒信号配置信息可以包括：唤醒信号的监听机会配置信息。该监听机会配置信息指的是时域位置信息。
需要说明的是，每一个信标信号的起始位置与符号的起始位置是对齐的。根据信标信号监听集的时域图案配置，例如，图8中，网络侧设备与终端可以获知一个信标信号集合内的所有信标信号所在的如下两个时间位置信息：
1，符号位置信息；
2，Slot位置信息。
此外，信标信号承载第一指示信息，第一指示信息包括：
(1)***帧(第一时间单元)索引信息，例如，图8中，指示当前信标监听周期内信标信号集合所在的***帧索引为1；
(2)半帧指示信息；例如，当前为***帧的前半帧。
(3)所述信标信号的索引信息；每个信标信号都会携带其对应的索引信息。
终端根据检测到的信标信号，能够确定如下时间信息：
(1)符号边界定时；
(2)Slot边界定时；
(3)半帧边界的定时；
(4)获取当前的无线帧编号。
由此，终端可以实现不同时间单元级别上的同步，继而纠正时域偏移。
在本申请实施例中，通过第一信号承载和/或网络侧设备/协议配置信标信号的时间位 置信息，实现在终端接收第一信号的同时进行下行的同步或定时，从而实现时偏纠正，并提高唤醒信号接收的可靠性。
