为更好理解本申请实施例的方案，首先对以下内容进行介绍：
低功耗唤醒
现有无线保真场景中可以采用一种低功耗唤醒接收机，如图1b所示，低功耗唤醒接收机包含两个部分：主接收机与唤醒接收机。主接收机用来进行无线保真数据发送和接收，唤醒接收机用来唤醒主接收机，未被唤醒前，主接收机处于关闭状态,不进行数据发送和接收。唤醒接收机接收发送端(例如接入点(Access Point，AP))发送的唤醒信号，唤醒信号可以为开关键控(On-Off Keying，OOK)调制信号，从而使得唤醒接收机可以采用包络检波的方式检测唤醒信号，可将功耗降低至几百微瓦量级，大大降低了用户的功 耗。
唤醒信号非连续接收
为进一步降低唤醒接收机的功耗，还采用唤醒信号非连续接收的方式，用户与AP通过唤醒无线电(Wake-up Radio，WUR)模式建立过程确定唤醒信号非连续接收的周期，起始位置，与接收时间长度。如图1c所示,用户在每个工作周期(duty cycle)内的占空比服务期(duty cycle service period)通过唤醒接收机接收唤醒信号，其中占空比周期(duty cycle period)与duty cycle service period的长度由用户通过发送WUR模式元素(mode element)告知给AP，duty cycle service period的长度小于或等于duty cycle period的长度，且duty cycle service period的长度要大于或等于AP指示的最小醒来时间长度，当AP回复确认用户WUR mode element中所携带的duty cycle period与duty cycle service period的长度后，用户将它们作为该用户非连续周期的参数。另一方面，duty cycle service period的起始位置，即图1c中所示起始点(start point),由AP发送的mode element所指示，采用64比特指示起始位置的TSF时间，时间单位为微秒。
WUR beacon信号
为保持低功耗唤醒接收机与AP间同步，采用周期性发送WUR beacon信号来传递时间信息，如图1d所，WUR beacon MAC frame的类型相关控制(type dependent control)携带AP的定时同步功能(Timing Synchronization Function，TSF)时钟(timer)64比特中的[5:16]共12比特信息，用户收到该12比特信息后，根据时间更新准则，更新用户本地的TSF timer,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发送的操作单元(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(Carrier Sense Multiple Access，CSMA)延迟(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，通过具体的实施例及其应用场景对本申请实施例提供的方法及装置进行详细地说明。
参见图2a，本申请实施例提供一种非连续接收方法方法，该方法的执行主体可以为终端，具体步骤包括：
步骤201：终端周期性从发送端接收前导序列；
步骤202：终端根据前导序列的时间位置，确定下一个非连续接收(Discontinuous Reception，DRX)周期接收唤醒信号的时间窗的起始位置；
具体地，本申请实施例中的终端具体可以是应用到NR系统中的移动终端，其具体结构可以如图2b中所示，包含两个模块，第一模块为主通信模块，用于移动通信数据的收发，第二模块为低功耗唤醒接收模块，用于接收唤醒信号。主通信模块一段时间无数据的接收和发送时，进入关闭或睡眠状态，当第二模块检测到发送端发送的唤醒信号，且该唤醒信号包含本接收端信息，则触发唤醒第一模块，第一模块进入工作状态，可进行数据接收和发送，未被第二模块唤醒时第一模块处于关闭或睡眠状态，不接收发送数据。
进一步地，第二模块可采用非连续接收唤醒信号，如图2c所示，第二模块在每个DRX周期醒来一段时间，在唤醒信号时间窗内接收唤醒信号，在其余时间进入睡眠状态，以进一步省电。
在本申请实施例中，通过周期性接收的前导序列，为低功耗唤醒接收机周期性更新参考时间信息，从而能够确定非连续接收周期接收唤醒信号的时间窗的起始位置，有效解决时钟精度较差导致的时间漂移的问题，并且通过序列携带相对时间信息，与采用信令显式指示时间信息相比，可降低信令开销和低功耗唤醒接收机译码提取时间信息的复杂度。
在一种可能的实施方式中，方法还包括：
终端从发送端接收第一配置，第一配置中包括以下一项或者多项：
(1)接收唤醒信号的周期；
(2)接收唤醒信号的起始位置偏移量；
(3)接收唤醒信号的DRX周期内偏移量
(4)接收唤醒信号的时间窗口的大小。
在本申请实施例中，对于一个给定的接收端(本申请实施例中作为执行主体的终端即为接收端)，或一组给定的接收端，配置接收唤醒信号的时间和频率域的位置，其中时间域的位置的包括上述的一个或者多个配置。
前导序列为用于一个或一组终端检测的专用前导序列，或者，前导序列为用于多个或多组终端检测的公共前导序列。
在一种可能的实施方式中，终端根据前导序列的时间位置，确定下一个非连续接收DRX周期接收唤醒信号的时间窗的起始位置，包括：
在前导序列为专用前导序列的情况下，终端根据检测到的当前DRX周期的专用前导序列的时间位置，确定下一个DRX周期接收唤醒信号的时间窗的起始位置。
在一种可能的实施方式中，在所述前导序列为所述公共前导序列的情况下，所述第一配置还包括以下一项或者多项：
接收公共前导序列的周期；
接收公共前导序列的起始位置偏移量；
终端根据前导序列的时间位置，确定下一个非连续接收DRX周期接收唤醒信号的时间窗的起始位置，包括：
在前导序列为公共前导序列的情况下，终端根据检测到的最新的公共前导序列的时间位置，确定下一个DRX周期接收唤醒信号的时间窗的起始位置。
在一种可能的实施方式中，终端根据前导序列的时间位置，确定下一个非连续接收DRX周期接收唤醒信号的时间窗的起始位置，还包括：
在两个公共前导序列之间，终端检测到专用前导序列的情况下，终端根据专用前导序列的时间位置，更新下一个DRX周期接收唤醒信号的时间窗的起始位置。
下面按照前导序列为公共前导序列和专用前导序列的情况，对本申请的方案做具体描述：
方案一、前导序列为专用前导序列，方法流程如下：
对于一个给定的接收端，或一组给定的接收端，配置接收唤醒信号的时间和频率域的位置，其中时间域的位置的包括以下的一个或者多个配置：
(1)DRX周期–接收唤醒信号的周期；
(2)接收唤醒信号的起始位置偏移量；
(3)接收唤醒信号的DRX周期内偏移量
(4)接收唤醒信号的时间窗口的大小；
发送端在该唤醒信号的每个DRX周期的固定位置发送专用前导序列，周期内的固定位置根据接收唤醒信号的DRX周期内偏移量确定，专用前导序列为该接收端或该接收端组专用，接收端的低功率唤醒接收模块根据检测到的当前DRX周期的专用前导序列的时间位置，确定唤醒信号下一个DRX周期接收唤醒信号的时间窗的起始位置。
具体方法为：接收端根据在第n-1个DRX周期检测到的专用前导序列，确定得到该序列的起始位置，标记为t’ n-1，则接收端以t’ n-1作为新的参考时间位置，加上一个T DRX时间偏移，减去一个delta，得到第n个DRX周期的接收唤醒信号的时间窗的起始位置为t’ n-1+T DRX-delta，其中T DRX为DRX周期的长度，delta为进一步降低低功耗唤醒接收机模块时钟漂移带来的误差影响，delta可以通过网络配置或接收端根据实现方式确定，值大于等于0。
类似地，接收端在每个DRX周期检测到前导序列后，确定为新的参考时间位置，并基于此确定下一个DRX周期接收唤醒信号的时间窗的起始位置，如图3a所示。
若接收端在第n-1个DRX周期检测专用前导序列成功，但在第n个DRX周期检测失败，则不更新参考时间位置，仍以t’ n-1作为参考时间位置，加上二个T DRX时间偏移，得到第n+1个DRX周期接收唤醒信号的时间窗的起始位置为t’ n-1+2*T DRX-delta.
进一步地，发送端根据在一个DRX周期是否需要唤醒接收端，选择唤醒信号格式，在第n个DRX周期，若无唤醒需求，发送端仅发送专用前导序列，专用前导序列的起始位置标记为t n；若有唤醒需求，则发送端发送专用前导序列和数据负载，如图3b所示，为指示专用前导序列后是否有数据负载，对于同一个接收端(组)，可以采用两个不同专用前导序列，序列一指示后续有数据负载，序列二指示后续无数据负载。另外，不同接收端(组)间可以采用不同专用前导序列，用来识别接收端(组)，当唤醒信号对应一个接收端组且组内包含大于一个接收端时，数据负载中还至少包含接收端组中的至少一个接收端标识，用以确定待唤醒的接收端。
针对上述方案一，提供一种具体应用实施例：
在本实施例中，发送端为基站，接收端为用户，分别为用户1-8，其中用 户1-4组成一个用户组，标识为用户组1，用户5-8组成另一个用户组，标识为用户组2。在实际应用中，发送端和接收端还可以都为用户。
基站通过主通信模块高层信令，如RRC信令为用户组1和用户组2分别配置接收唤醒信号的周期，接收唤醒信号的起始位置偏移量；接收唤醒信号的DRX周期内偏移量；接收唤醒信号的时间窗口的大小；标记为T1 DRX，t1 start，t1 shift，W1，及T2 DRX，t2 start，t2 shift，W2。两个用户组的DRX配置可以相同或不同，t1 start和t2 start为相对系统帧SFN0的时间偏移。
假定用户组1中的用户1和2以及用户组2中的用户5和8在一段时间内均无数据的接收和发送，因此用户1和2以及用户5和8将主通信模块关闭或睡眠，通过低功耗唤醒接收模块按照DRX周期监听唤醒信号，即在每个DRX周期醒来监听专用前导序列以及后续数据，在其余时间低功耗唤醒接收模块也处于睡眠状态，从而省电。
假定用户组1采用的专用前导序列为序列1和2，其中序列1用来指示序列后无数据负载，低功耗唤醒接收模块在接收序列后可直接进入睡眠状态。序列2用来指示序列后有数据负载，在接收完数据并译码确定唤醒用户标识后，用户标识包含在数据负载中的用户的低功耗唤醒接收模块触发主通信模块醒来进入工作状态，其它用户的低功耗唤醒接收模块进入睡眠状态。
类似地，用户组2采用的专用前导序列为序列3和4，其中序列3用来指示序列后无数据负载，低功耗唤醒接收模块在接收序列后可直接进入睡眠状态。序列4用来指示序列后有数据负载，在接收完数据并译码确定唤醒用户标识后，用户标识未被包含在数据负载中的用户的低功耗唤醒接收模块进入睡眠状态，其它用户触发主通信模块醒来进入工作状态。
其中用户组与专用前导序列的关联关系可以由基站的高层信令显示配置，还可以通过预设规则计算得到，比如用户1-4根据每个用户的标识，如TMSI，采用类似于paging用户的分组取模运算，得到用户组的标号，在本实施例中假设计算得到标号为1，设定系统中共有两个前导序列池，池1和池2，则预设准则可以为从池1和池2中分别选择标号为1的前导序列分别作为用户组1的专用前导序列1和专用前导序列2。
参照图3a，基站在用户组1的每个DRX周期发送专用前导序列1或2， 当发送序列2时还同时发送数据负载。用户组1中的用户1和2通过主通信模块由基站的高层信令得到T1 DRX，t1 start，t1 shift，W1，且用户1和2通过主通信模块已和基站建立下行同步，因此可以确定一个启动监听唤醒信号的起始位置t1 start+X*T1 DRX+t1 shift其中X的取值使得启动监听唤醒信号的时间位置不晚于主模块进入关闭和睡眠状态的时间。因此，从时刻t1 start+X*T1 DRX+t1 shift开始，用户1和2每个周期醒来监听唤醒信号，基站在第n-1个DRX周期发送专用前导序列2和数据负载，其中数据负载中包含用户2的标识，用户1和2在第n-1个DRX周期检测到前导序列2，确定得到该序列的起始位置，标记为t’ n-1，则用户1和2以t’ n-1作为新的参考时间位置，加上一个T DRX时间偏移，减去一个delta，得到第n个DRX周期的接收唤醒信号的时间窗的起始位置为t’ n-1+T DRX-delta，用户1和2译码序列2后的数据负载，用户2确定其用户标识包含在数据负载中，因此触发主通信模块醒来进入工作状态。用户1的低功率唤醒接收模块回到睡眠状态。
类似地，用户组2的用户5和8通过监听专用序列3和4来确定唤醒信号下一个DRX周期接收唤醒信号的时间窗的起始位置。以及根据数据负载所包含的用户标识确定是否唤醒主通信模块。
在以上实施例中，前导序列和数据负载可以采用OOK调制方式，因此，为便于接收端时间累计，周期T DRX可以采用OOK符号长度的整数倍的数值。
方案二、前导序列为公共前导序列，方法流程如下：
发送端周期性发送公共前导序列，多个接收端或多组接收端周期性检测公共前导序列。
对于一个给定的接收端，或一个给定的接收端组，配置接收唤醒信号的时间和频率域的位置，其中时间域的位置的包括以下的一个或者多个配置：
(1)DRX周期：接收唤醒信号的周期，T DRX；
(2)接收唤醒信号的起始位置偏移量，T offset；
(3)接收唤醒信号的DRX周期内偏移量，T shift；
(4)接收唤醒信号的时间窗口的大小；
对于多个接收端或多组接收端，配置接收公共前导序列的时间和频率域的位置，其中时间域的位置的包括以下的一个或者多个配置：
(1)周期：接收公共前导序列的周期；
(2)接收公共前导序列的起始位置偏移量；
低功率唤醒接收机根据检测到的最新公共前导序列的时间位置，确定唤醒信号下一个DRX周期接收唤醒信号的时间窗的起始位置。在两个公共前导序列间，若一个给定的接收端或接收端组检测到其专用前导序列，则根据专用前导序列的时间位置，更新下一个唤醒信号DRX周期的起始位置。
具体方法为：如图3c所示，发送端周期性发送公共前导序列，发送周期为T preamble，起始位置为t 0，多个接收端或多组接收端按T preamble周期性检测公共前导序列。对于一个给定的接收端或接收组，发送端当有唤醒需求时发送唤醒信号，发送周期为T DRX，起始位置为t 0+T offset，其中T offset为相对于公共前导序列起始位置t 0的时间偏移。接收端低功率唤醒接收机按照T preamble和T DRX周期性醒来监听公共前导序列和唤醒信号，其余时间处于睡眠状态。
接收端根据在第m-1个周期检测到的公共前导序列，确定得到该序列的起始位置，标记为t’ m-1，则接收端以t’ m-1作为新的参考时间位置，加上一个时间差T gap，得到唤醒信号第n-1个DRX周期监听唤醒信号时间窗的起始位置为t’ n-1＝t’ m-1+T gap，其中时间差为T gap＝T offset+T shift+(n-2)*T DRX-(m-2)*T preamble-delta。更进一步地，在两个公共前导序列间，若接收端检测到其专用前导序列，则根据专用前导序列的时间位置，更新下一个唤醒信号DRX周期的起始位置，因此，接收端根据在第n-1个DRX周期检测到的专用前导序列，确定得到该序列的起始位置为t’ n-1，将其作为新的参考时间位置，加上一个TDRX时间偏移，减去一个delta，得到唤醒信号第n个DRX周期监听唤醒信号时间窗的起始位置为t’ n-1+T DRX–delta。
进一步地，发送端在一个DRX周期仅当有唤醒用户需求时，发送唤醒信号，否则不发送任何信号。
在本方案二中，一种替代的方法为，发送端不周期性发送公共前导序列，发送端在接收端未发送唤醒信号的DRX周期，发送公共前导序列，接收端仅按照DRX周期醒来接收唤醒信号进行序列检测。接收端不按照T preamble检测公共前导序列。
具体方法为：接收端根据在第n-1个DRX周期检测到的专用前导序列或 公共前导序列，确定得到该序列的起始位置，标记为t’ n-1，则接收端以t’ n-1作为新的参考时间位置，加上一个T DRX时间偏移，减去一个delta，得到第n个DRX周期的接收唤醒信号的时间窗的起始位置为t’ n-1+T DRX-delta，其中T DRX为DRX周期的长度，delta为进一步降低低功耗唤醒接收机模块时钟漂移带来的误差影响，delta可以通过网络配置或接收端根据实现方式确定，值大于等于0。
针对上述方案二，提供一种具体应用实施例：
在本实施例中，发送端为基站，接收端为用户，分别为用户1-8，其中用户1-4组成一个用户组，标识为用户组1，用户5-8组成另一个用户组，标识为用户组2。在实际应用中，发送端和接收端还可以都为用户。
基站通过主通信模块高层信令，如SIB信令配置公共前导序列发送的起始位置t0和周期T preamble。通过主通信模块高层信令，如RRC信令为用户组1和用户组2分别配置唤醒信号发送的DRX周期，接收唤醒信号的起始位置偏移量，接收唤醒信号的DRX周期内偏移量,接收唤醒信号的时间窗口的大小，标记为T1 DRX，T1 offset，T1 shift，W1，及T2 DRX，T2 offset，T2 shift，W2。两个用户组的DRX配置可以相同或不同，T1 offset和T2 offset为相对t0的时间偏移。
假定用户组1中的用户1和2在一段时间内均无数据的接收和发送，因此两个用户将主通信模块关闭或睡眠，通过低功耗唤醒接收模块按照T1 DRX周期监听唤醒信号，即在每个DRX周期醒来监听是否要唤醒主模块。为更准确确定每个DRX周期起始位置的时间，用户在每个公共前导序列的周期醒来监听公共前导序列，在监听公共前导序列和唤醒信号以外的时间用户1和2的低功耗唤醒接收模块处于睡眠状态，从而省电。
假定用户组1采用的专用前导序列为序列1，当用户1和2检测到序列1，并在接收完数据并译码确定唤醒用户标识后，用户标识包含在数据负载中的用户的低功耗唤醒接收模块触发主通信模块醒来进入工作状态，其它用户的低功耗唤醒接收模块进入睡眠状态。
其中用户组与专用前导序列的关联关系可以由基站的高层信令显示配置，还可以通过预设规则计算得到，比如用户1-4根据每个用户的标识，如临时移动签约标识(Temporary Mobile Subscription Identifier，TMSI)，采用类似于 寻呼(paging)用户的分组取模运算，得到用户组的标号，在本实施例中假设计算得到标号为1，设定系统中共有一个专用前导序列池，则预设准则可以为从专用前导序列池中选择标号为1的前导序列作为用户组1的专用前导序列。
参照图3c，基站按起始位置t0和周期T preamble发送公共前导序列，同时当需要唤醒用户1和2时，按T1 DRX,T1 offset，T1 shift在用户组1最近的唤醒信号DRX周期发送唤醒信号。用户1和2在主模块关闭或睡眠前已经和基站建立下行同步，因此可以确定一个开始监听公共前导序列的时间为t0+X*T preamble，还可以确定开始监听唤醒信号的时间为t0+T1 offset+T1 shift+X’*T1 DRX，其中X，X’的取值使得开始监听公共前导序列和唤醒信号的时间位置不晚于主模块进入关闭和睡眠状态的时间。
因此，从时刻t0+X*T preamble开始，用户1和2开始每个周期醒来监听公共前导序列，从时刻t0+T1 offset+T1 shift+X’*T1 DRX开始，用户1和2开始每个周期醒来监听唤醒信号。
用户1和2根据在第m-1个周期检测到的公共前导序列，确定得到该序列的起始位置，标记为t’ m-1，则接收端以t’ m-1作为新的参考时间位置，加上一个时间差T gap，得到唤醒信号第n-1个DRX周期监听唤醒信号时间窗的起始位置为t’ n-1＝t’ m-1+T gap，其中时间差为T gap＝T offset+T shift+(n-2)*T DRX-(m-2)*T preamble-delta。用户1和2在t’ n-1醒来监听唤醒信号，根据检测到的专用前导序列，确定数据负载的符号位置，译码数据，得到数据负载中包含用户1的标识，则用户1触发主通信模块醒来进入工作状态，用户2的低功率唤醒接收模块回到睡眠状态。
为更一步降低低功耗唤醒接收机的功耗，唤醒信号还可以采用如图3d的形式，在专用前导序列前发送一个分节符，在未正确检测到分节符前，低功耗唤醒接收机仅处在能耗非常低的模式，而仅在检测到分节符后才进行前导序列的匹配检测，较一直进行序列检测相比，可进一步降低功耗。
在以上实施例中，前导序列和数据负载可以采用OOK调制方式，因此，为便于接收端时间累计，周期TDRX可以采用OOK符号长度的整数倍的数值。
在本实施例中，一种替代的方法为，发送端不周期性发送公共前导序列，发送端在接收端未发送唤醒信号的DRX周期，发送公共前导序列，接收端仅按照DRX周期醒来接收唤醒信号进行序列检测。接收端不按照T preamble检测公共前导序列。
具体方法为：接收端根据在第n-1个DRX周期检测到的专用前导序列或公共前导序列，确定得到该序列的起始位置，标记为t’ n-1，则接收端以t’ n-1作为新的参考时间位置，加上一个T DRX时间偏移，减去一个delta，得到第n个DRX周期的接收唤醒信号的时间窗的起始位置为t’ n-1+T DRX-delta，其中T DRX为DRX周期的长度，delta为进一步降低低功耗唤醒接收机模块时钟漂移带来的误差影响，delta可以通过网络配置或接收端根据实现方式确定，值大于等于0。
