Description

一种唤醒信号发送方法及装置
本申请要求于2021年9月28日提交国家知识产权局、申请号为202111146311.5、申请名称为“一种WUR的帧结构设计方法”、以及于2021年11月05日提交国家知识产权局、申请号为202111308989.9、申请名称为“一种唤醒信号发送方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种唤醒信号发送方法及装置。
背景技术
目前，用户设备(user equipment，UE)在空闲态(IDLE)/非激活态(INACTIVE)态下的时候，UE会根据自己的UE标识(UE ID)计算得到一个寻呼帧(paging frame，PF)以及一个PF中的寻呼时机(paging occasion，PO)的位置，在PO内接收寻呼。UE无论在IDLE态/INACTIVE态执行上述接收寻呼的流程时，还是UE在连接态进行数据接收时，都是用相同的接收模块。
为了进一步降低UE的功耗，可以使用一个单独的低功耗小电路接收寻呼相关的消息，这个小电路可以被称为唤醒电路或低功耗电路或其他名字，唤醒电路接收的信号可以被称为唤醒信号/无线电(wake up signal/radio，WUS/WUR)。UE如何准确地识别唤醒电路接收到的WUR信号中的信息成为亟待解决的问题。
发明内容
本申请实施例提供一种唤醒信号发送方法及装置，解决UE如何准确地识别唤醒电路接收到的WUR信号中的信息的问题。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种唤醒信号发送方法，所述方法包括：终端接收来自网络设备的同步信号，在第一时域资源上接收来自网络设备的至少用于指示寻呼相关的信息的唤醒信号；其中第一时域资源的格式设计为：第一时域资源包括N个预设长度的第一时间单元，一个唤醒信号占用N个预设长度的第一时间单元中的至少一个第一时间单元，第一时间单元的边界位置根据同步信号的时域位置确定。
相应的，第二方面，本申请实施例还提供一种唤醒信号发送方法，该方法可以由网络设备执行，该方法可以包括：网络设备向终端发送同步信号，网络设备在第一时域资源上向终端发送至少用于指示寻呼相关的信息的唤醒信号；其中第一时域资源以及第一时间单元的设计如第一方面中所述，不予赘述。
基于上述方法，本申请定义了用于传输唤醒信号的时域资源以及该时域资源的边界位置，比如根据同步信号的时域位置确定用于传输唤醒信号的时间单元的边界位置，以便终端获知唤醒信号的起始位置以及都在哪些时域位置上检测/接收唤醒信 号，减少终端解码与寻呼相关的信息(比如寻呼消息)的次数(即仅在第一时间单元的边界位置才尝试解码，而非在任意符号位置都尝试解码)，进而降低终端的虚警概率，避免终端现有方式在任意符号位置都尝试解码带来的虚警概率较大的问题。
一种可能的设计中，第一时间单元包括多个符号，其中一个符号对应一个编码比特。如此使得一个符号传输一个编码比特，从格式上与现有系统(比如NR系统)的格式区分开来。
一种可能的设计中，第一时间单元的边界位置根据同步信号的时域位置确定包括：第一时间单元的边界位置根据同步信号的起始位置确定或者第一时间单元的边界位置根据同步信号的结束位置确定，基于该可能的设计，可以有效且灵活的根据同步信号的时域位置确定第一时间单元的边界位置，简化系统设计。

一种可能的设计中，唤醒信号包含用于指示唤醒信号占用的第一时间单元的索引值，或者唤醒信号占用的起始时间单元的索引值的指示信息，如此可以便于终端根据唤醒信号中携带的指示信息确定当前接收的唤醒信号的处于哪个位置，提高接收的准确性。
一种可能的设计中，终端接收来自网络设备的唤醒信号，包括：终端获取用于指示第一时域资源的索引值的定时索引，根据定时索引和用于配置时间窗的第一配置信息在时间窗内接收来自网络设备的唤醒信号，该时间窗包括在第一时域资源中或者时间窗包括第一时域资源。基于该可能的设计，终端可以进行系统定时，定位自己接收唤醒信号的时间位置，以便在该时间位置提前醒来为接收唤醒信号做准备，提高唤醒信号接收的准确性。
一种可能的设计中，定时索引根据携带在同步信号中的第一信息确定；或者，定时索引与同步信号的同步序列之间存在映射关系，定时索引根据映射关系以及同步信号的同步序列确定；或者，定时索引根据第二信息和同步信号的同步序列确定，基于该可能的设计，有效且灵活的获取定时索引，简化系统设计。
一种可能的设计中，定时索引根据第二信息和同步信号的同步序列确定包括：定时索引由M1个携带在同步信号中的信息比特以及M2个信息比特确定；第二信息包括M1个信息比特，M2个信息比特与同步信号的同步序列之间存在映射关系，M2个信息比特根据同步信号的同步序列确定，M1、M2为正整数。基于该可能的设计，可以根据同步信号中的信息比特以及同步序列综合确定定时索引，简化系统设计。
一种可能的设计中，第一时域资源的起始位置为同步信号的结束位置；或者，第一时域资源的起始位置为同步信号的结束位置之后、距离同步信号的结束位置第三预 设间隔的位置。第一时域资源的结束位置为同步信号相邻的下一同步信号的起始位置或者第一时域资源的结束位置为同步信号相邻的下一同步信号之前、距离同步信号相邻的下一同步信号的起始位置第四预设间隔的位置。如此可以灵活且有效地确定第一时域资源的边界位置。
一种可能的设计中，唤醒信号包括第一唤醒信号和第二唤醒信号，第一唤醒信号的数据率低于第二唤醒信号的数据率，第一唤醒信号占用的第一时间单元个数大于第二唤醒信号占用的第一时间单元个数，如此根据需要设计不同数据率的唤醒信号所占用的时间单元的数量，简化系统设计，且满足不同终端的数据率需求。
一种可能的设计中，网络设备向终端发送用于配置预留资源的第二配置信息，终端接收第二配置信息，以使得终端根据第二配置信息在该预留资源上不能发送同步信号，预留资源包括在同步信号的候选发送位置中，同步信号的候选发送位置根据同步信号的发送周期确定，如此可以使得终端避开与其他终端在同一位置上发送同步信号所带来的干扰问题。
一种可能的设计中，同步信号的波形与唤醒信号的波形相同；和/或，同步信号的调制方式与唤醒信号的调制方式相同，同步信号的调制方式与唤醒信号的调制方式为开关键控(on-off keying，OOK)OOK，和/或，同步信号的波形和/或唤醒信号的波形为OOK。如此，灵活且有效的设计同步信号、唤醒信号的波形以及调制方式。
一种可能的设计中，唤醒信号用于指示的需要接收寻呼的一个或多个终端包括终端；所述方法还包括：终端接收来自网络设备的第一信息和/或进行随机接入，其中，第一信息包括以下一项或多项信息：寻呼下行控制信息(downlink control information，DCI)，寻呼消息(paging message)，寻呼提前指示(paging early indication，PEI)。如此可以便于终端接入网络，与网络设备进行通信。

具体实施方式
介绍本申请实施例之前，对本申请实施例涉及的一些名词(如寻呼等)进行解释说明。需要说明的是，下述解释说明是为了让本申请实施例更容易被理解，而不应该视为对本申请实施例所要求的保护范围的限定。
寻呼(paging)：是网络设备周期性地向处于空闲(idle)态或者非激活(inactive)态的终端发送寻呼消息(paging message)，以唤醒处于idle态或者inactive态的终端回到连接(connected)态的过程。该过程包括：网络设备(如接入网设备)计算终端对应的寻呼帧(paging frame，PF)以及PF中的寻呼时机(paging occasion，PO)，在终端对应的PO上向终端发送携带寻呼DCI的物理下行控制信道(physical downlink control channel，PDCCH)，寻呼DCI可以调度携带寻呼消息(paging message)的物理下行共享信道(physical downlink control channel，PDSCH)。如果寻呼DCI指示调度了携带寻呼消息的PDSCH，则网络设备在寻呼DCI指示的资源位置上发送携带寻呼消息的PDSCH。相应的，终端在自己对应的PO上监测寻呼DCI，若终端接收到寻呼DCI，根据接收到的寻呼DCI接收携带寻呼消 息的PDSCH，根据携带寻呼消息的PDSCH确定自己是否被寻呼，比如，如果终端接收到的寻呼消息中携带有自己的标识信息(如用户设备标识(user equipment identifier，UE ID))，则确定自己被寻呼到，反之，则确定自己未被寻呼到。如果终端被寻呼到，则终端发起随机接入流程，切换到连接(connected)态，与网络设备建立通信连接，进而与网络设备进行数据通信。
目前，终端的寻呼过程以及连接态下的数据通信过程均使用相同的功能模块，该功能模块可以称为主电路或者第二模块。但是，相对于连接态下的数据通信而言，执行寻呼的过程可能不需要过多的功率消耗，而利用主电路执行寻呼过程可能会带来更多的功率消耗。因此为了进一步降低终端的功率消耗，可以在终端上分别独立部署一个主电路和一个单独的低功耗小电路，这个低功耗小电路可以实现在低功耗的情况下接收寻呼相关的信息，比如接收来自网络设备的需要寻呼的一个或者多个终端的信息等。
本申请实施例中，低功耗小电路主要用于支持处于idle态或者inactive态的终端接收寻呼相关的信息。其中低功耗小电路可以称为唤醒电路或者低功耗电路或者唤醒信号(wake up signal，WUS)接收机或者唤醒无线电(wake up radio，WUR)接收机或者第一模块或者第一电路等，不予限制。本申请中以唤醒电路为例进行描述，在此统一说明，不再赘述。其中唤醒电路接收到的信号可以称为WUR信号，WUR信号可以包括与寻呼有关的信号，比如WUR信号可以包括唤醒信号，还可以包括同步信号。该唤醒信号至少用于指示寻呼相关的信息(如用于指示需要接收的终端的信息)，唤醒信号还可以命名为WUS信号或者唤醒无线电(wake up radio，WUR)信号等。使用唤醒电路接收WUR信号(比如唤醒信号)可以理解为在WUR链路上工作，或者在WUR链路上接收唤醒信号，或者在第一状态/第一模式(model)下接收WUR信号等。
本申请实施例中，主电路主要用于支持处于连接态的终端与网络设备进行数据通信，也可以用于支持终端接入网络设备，也可以用于支持终端执行现有标准中的寻呼过程(即接收寻呼DCI以及寻呼PDSCH等)。主电路可以称为第二模块或者第二电路或者其他名称。使用主电路进行数据通信可以理解为使用主链路进行数据通信，或者在第二状态/第二模块下进行数据通信等。
本申请实施例中，第一状态可以理解为终端开启唤醒电路，关闭主电路时的状态，第一状态可以称为WUR状态或者唤醒状态或者命名为其他状态，不予限制。第一模式可以理解为第一工作模式或者WUR模式或者唤醒模式或者WUR工作模式，第一模式可以指终端在第一状态下工作或者终端在WUR链路上工作或者终端使用/利用唤醒电路工作等。
本申请实施例中，第二状态可以理解为终端关闭唤醒电路、开启主电路时的状态，第二状态可以称为主状态或者命名为其他状态，不予限制。第二模式可以理解为第二工作模式或主模式或者主工作模式，第二模式可以指终端在第二状态下工作或者终端在主链路上工作或者终端使用/利用主电路工作等。
例如，如图1所示，终端内部署有唤醒电路以及主电路，当终端处于第一状态(比如WUR状态)或者idle态或者inactive态时，唤醒电路开启(或者称为工作)，主电路关闭(或者称为不工作)，终端可以利用/使用唤醒电路接收唤醒信号，若终端检测到唤醒自己的唤醒信号，则触发开启主电路，使得主电路处于开启状态。若终端未检测到唤醒信号，则终端不触发开启主电路，此时主电路处于关闭状态。通过图1所示方式可以降低终端的功率消耗。
本申请实施例中，为了降低唤醒电路的功率消耗，唤醒信号使用二进制振幅键控(比如开关键控(on-off keying，OOK))调制，相应的，唤醒电路可以采用包络检测的方法(或者0/1判决方法)解调唤醒信号。当采用OOK调制时，唤醒信号被编码后的一个信息比特(或者称为被编码后的比特或编码比特)对应一个符号(symbol)。示例性的，当信息比特为1时，表示该信息比特对应的符号的长度内有信号发出(或者可以理解为该符号的长度内的信号功率不为零)，当信息比特为0时，表示该信息比特对应的符号的长度内无信号发出(或者可以理解为该符号的长度内的信号功率为零)。或者，当信息比特为0时，表示该信息比特对应的符号的长度内有信号发出(或者可以理解为该符号的长度内的信号功率不为零)，当信息比特为1时，表示该信息比特对应的符号的长度内无信号发出(或者理解为符号的长度内的信号功率为零)。
应理解，本申请中的符号还可以称为码片(chip)。符号的长度可以指该符号的起始位置至该符号的结束位置之间的时间长度。符号的长度可以是预先配置的或者协议预先规定好的。比如可以将一个符号的长度设置为4微秒(us)等。
由上可知，使用WUR链路工作时以符号为粒度传输唤醒信号，为了检测唤醒信号需要获知符号的边界位置，从符号的边界位置开始检测接收到的唤醒信号，检测符号上是否有信号，将多个符号对应的检测结果组合在一起确定得到的唤醒信号，根据唤醒信号判断是否自己被寻呼/被唤醒。例如，假设信息比特为1表示有信号，信息比特为0表示无信号，经过OOK调制的唤醒信号为“1010”，包括4个编码比特，这4个编码比特可以对应如图2所示四个符号，从左边开始的第一个、第三个符号的长度内信号功率大于零，有信号存在，第一个、第三符号对应编码比特“1”。第二个、第四个符号的长度内信号功率为零，无信号存在，对应的编码比特为0。此时，终端可以从第一个符号的边界开始在任意符号位置都尝试解码，得到唤醒信号1010，进而根据唤醒信号1010确定自己是否被唤醒。
可选的，通过同步(synchronization，sync)信号来定位WUR上传输的符号的边界位置。该同步信号可以用于终端进行时间同步。比如，一种可能的设计中，如图3a所示，随路发送同步信号，即唤醒信号和同步信号一起发送，唤醒信号的起始位置与同步信号的结束位置重叠，终端接收到同步信号并使用同步信号完成时间同步之后，可以直接定位到唤醒信号所在的符号的边界，进而在对应符号上检测唤醒信号。再一种可能的设计中，如图3b所示，周期性发送同步信号，在相邻两个同步信号之间的时间段(或者多个符号)上发送唤醒信号，终端接收同步信号并使用同步信号完成时间同步之后，可以获得符号定位，比如获得符号的边界位置(或者起始位置)， 以便根据符号的边界位置选择进行包络检测(或者称为0/1判决)的时间位置，比如以某个符号的中心位置进行判决。
但是，在周期性发送同步信号的过程中，终端从自己定位的符号边界开始在周期内按照符号顺序依次检测唤醒信号，即在任意符号位置都尝试解码，解码次数较多，会导致虚警概率较大。例如，如图3c所示，假设相邻同步信号之间存在140个符号：符号0-符号139。小区内包括UE1和UE2，UE1的标识为AB，UE2的标识为BC，如果基站要唤醒该小区中的UE1，则基站会在符号112-符号125上发送唤醒信号“AB”，其中“A”、“B”占用多个符号。对于UE1、UE2而言可以采用图3b所示方式，定位得到符号0的边界位置，从符号0的边界位置开始检测，直至检测到符号112-符号118得到“A”、检测符号119-符号125得到“B”，UE1根据检测结果确定自己被唤醒。而UE2发现检测结果“AB”不是自己的，继续检测符号126-符号132，此时如果符号126-符号132上有噪声干扰，UE2误将噪声干扰检测为“C”，则UE2结合符号119-符号125、符号126-符号132上的检测结果“BC”确定自己被唤醒，实际上此次唤醒的是UE1，而不是UE2，增大UE2的虚警概率。
为解决周期性发送同步信号的过程中终端虚警概率较大的问题，本申请实施例提供一种唤醒信号发送方法，该方法可以包括：网络设备在同步信号所在时域位置之后的第一时域资源上向终端发送唤醒信号，相应的，终端在第一时域资源上接收唤醒信号。其中该第一时域资源可以预先定义好的资源，该第一时域资源的格式如下：该第一时域资源包括N个第一时间单元，第一时间单元可以用于承载/传输唤醒信号，比如N个第一时间单元中的至少一个第一时间单元上承载有唤醒信号，第一时间单元的边界位置也预先定义好，比如第一时间单元的边界位置可以根据同步信号的时域位置确定。如此，可以定义好用于传输唤醒信号的时域资源以及该时域资源的边界位置，以便终端获知唤醒信号的起始位置以及都在哪些时域位置上检测/接收唤醒信号，减少终端解码与寻呼相关的信息(比如寻呼消息)的次数(即仅在第一时间单元的边界位置才尝试解码，而非在任意符号位置都尝试解码)，进而降低终端的虚警概率，避免终端现有方式在任意符号位置都尝试解码带来的虚警概率较大的问题。
应理解，本申请所述的唤醒信号至少可以用于指示寻呼相关的信息，如唤醒信号可以携带寻呼消息，比如被寻呼终端的UE ID、或者被寻呼终端的部分UE ID、或者被寻呼终端的组ID等，还可以携带其他信息，比如系统消息、系统配置等其他信息。唤醒信号属于在WUR链路上传输的信号中的一种。本申请中，在WUR链路上传输的信号可以称为WUR信号，除唤醒信号之外，WUR链路上还可以传输其他信号，比如同步信号等，此时WUR信号还可以包括同步信号等。
应理解，本申请所述的WUR链路可以指终端的唤醒电路与网络设备之间的通信链路，终端的唤醒电路可以支持终端通过WUR链路收发唤醒信号以及其他信号，比如同步信号等。当终端在WUR链路上工作时，终端的唤醒电路处于开启状态，终端的主电路处于关闭状态。可选的，可以为WUR链路预先配置传输资源，该传输资源可以包括时域资源和/或频域资源，通过WUR链路传输信号(比如唤醒信号等)可以理解为在WUR链路上传输信号或者利用/使用该WUR链路对应的传输资源传输信号 等。需要说明的是，本申请所述的时域资源还可以理解为时间资源，本申请所述的频域资源还可以理解为频率资源等。
应理解，本申请所述的主链路可以指终端的主电路与网络设备之间的通信链路，终端的主电路可以支持处于连接态的终端通过主链路与网络设备之间收发信号和/或进行数据传输。当终端在主链路上工作时，终端的主电路处于开启状态，终端的唤醒电路处于关闭状态。可选的，可以为主链路预先配置传输资源，该传输资源包括时域资源和/或频域资源，通过主链路传输信号可以理解为在主链路上传输信号或利用/使用该主链路对应的传输资源传输信号。
需要说明的是，本申请各实施例中的消息名称或消息中的参数名称等只是一个示例，具体实现中也可以采用其他的名称，例如本申请所述的时域资源还可以命名为时间资源或其他名称，时域资源可以包括多个小的时间段(或者称为时间长度)，换言之，时域资源可以被分多个时间段，一个时间段可以是一个符号或一个时隙(slot)或者一个调度单元或者毫秒(ms)时间等。本申请所述的频域资源还可以命名为频率资源或者其他名称，频域资源可以包括一个或者多个频域单元(或者称为频率单元)，该频域单元可以是资源单元(resource element，RE)或资源块(resource block，RB)或者物理资源块(physical resource block，PRB)。WUR链路可以称为第一链路，主链路可以称为第二链路，不予限制。

图6为本申请实施例提供的一种唤醒信号发送方法，如图6所示，所述方法可以包括：
步骤601：网络设备向终端发送同步信号；相应的，终端接收来自网络设备的同步信号。
其中，网络设备可以为图4中的网络设备。终端可以为图4中位于该网络设备的覆盖区域的终端，比如可以为图4中的终端1或者终端2。该终端至少可以具备三个 状态：idle态、inactive态、连接态。还可能具有额外的状态，例如为WUR状态。该终端可以具备/部署有如图1所示的低功耗电路(或者称为唤醒电路)以及主电路，当终端处于idle态或者inactive态或者WUR状态时，低功耗电路(或者称为唤醒电路)工作、主电路关闭，终端处于连接态时，主电路工作、低功耗电路(或者称为唤醒电路)关闭。应理解，执行图6所示方法时，终端处于idle态或者inactive态或者WUR状态。
本申请中，同步信号可以用于终端进行时间同步，比如可以定位符号的边界位置等。同步信号可以通过WUR链路传输，换言之，同步信号可以承载在WUR链路对应的传输资源(比如时域资源和/或频域资源)上传输，本申请中WUR链路对应的传输资源可以称为WUR资源，WUR资源可以包括一个或者多个WUR帧、第一频域资源。一种可能的设计中，一个WUR帧用于传输唤醒信号。又一种可能的设计中，一个WUR帧可以用于传输同步信号以及其他信号(比如唤醒信号等)。一个帧可以包括多个时间单元。具体的，WUR资源可以通过网络设备预先配置。WUR帧的作用可以通过网络设备预先配置，或者协议预先规定好。WUR链路的相关描述可参照上文，不予赘述。
本申请中，同步信号可以周期性的发送。其中同步信号的周期、同步信号的传输资源(比如时域起始位置/结束位置、频域起始位置/结束位置、时域长度等)可以是预先配置/设置好的，比如可以是协议预先规定的。
由于WUR链路上除了传输同步信号之外，还可以传输其他信号，比如唤醒信号。以唤醒信号为例，为了保证同步信号在WUR帧传输不被干扰，一种可能的设计中，可以设置同步信号的传输资源与该WUR链路上传输的唤醒信号的传输资源不重叠，如设置同步信号的时域资源与WUR链路上传输的唤醒信号的时域资源不重叠，二者之间存在一定的间隔(gap)，具体的可以为同步信号的结束位置与唤醒信号的起始位置二者之间存在gap，每个周期内的同步信号的时域资源的长度和间隔的长度是等同的/等长的，每个周期的同步信号的起始位置距离唤醒信号的传输资源的起始位置是等长的。该gap可以是预先设置的，或者又一种可能的设计中，同步信号的结束位置为唤醒信号的起始位置，即同步信号的结束位置与唤醒信号的起始位置重叠。具体的，WUR上传输的同步信号的传输资源与其他信号(比如唤醒信号)的传输资源之间的位置关系可以预先设置，不予限制。
需要说明的是，本申请实施例中，同步信号的传输资源可以指允许同步信号占用的时域资源或者可用于承载同步信号的时域资源或者同步信号候选发送位置，同步信号的传输资源的长度还可以替换描述为同步信号的长度，同步信号占用的传输资源块可以指同步信号的传输资源中实际被同步信号占用的传输资源，同步信号占用的传输资源可以小于或等于同步信号的传输资源。类似的，唤醒信号的传输资源可以是允许唤醒信号占用的传输资源或者可用于承载唤醒信号的传输资源或者唤醒信号候选发送位置，唤醒信号的传输资源的长度可以替换描述为唤醒信号的长度。此时，对于唤醒信号的传输资源，唤醒信号是否真的占用该传输资源，取决于是否有终端被寻呼。唤醒信号占用的传输资源可以是唤醒信号的传输资源中实际被唤醒信号占用的传输资源。
示例性的，网络设备可以将同步信号承载在预先配置好的传输资源上，周期性地通过WUR链路向终端发送同步信号。相应的，终端使用/利用其内部署的唤醒电路(或者称为低功耗电路或者第一模块)，在WUR链路上周期性地接收来自网络设备的同步信号。应理解，本申请所述的终端在WUR链路上周期性地接收来自网络设备的同步信号还可以替换描述为终端通过第一模块接收来自网络设备的同步信号，或者终端在第一状态或第一模式下周期性地接收来自网络设备的同步信号。
可选的，为了便于终端检测出同步信号，网络设备可以将同步信号进行OOK调制后向终端发送，此时同步信号的调制方式为OOK或者同步信号的波形是OOK，例如同步信号的波形可以为如图2所示的方波，或者同步信号的波形可以为基于正交频分复用(orthogonal frequency division multiplexing，OFDM)信号构造出的类似方波的波形。
步骤602：网络设备在第一时域资源上向终端发送唤醒信号。相应的，终端在第一时域资源上接收来自网络设备的唤醒信号。
进一步的，如果该终端包括在唤醒信号指示的需要接收寻呼的一个或者多个终端中，即唤醒信号包括的用于指示需要接收寻呼的一个或者多个终端的信息中有该终端对应的信息，则意味着该终端需要被唤醒，图6所示方法还可以包括：网络设备向终端发送第一信息和/或与终端交互执行随机接入过程，其中与终端交互执行随机接入过程可以包括网络设备接收终端发送的前导码等。相应地，终端接收来自网络设备的第一信息和/或进行随机接入。第一信息包括寻呼DCI、寻呼消息和寻呼提前指示(paging early indication，PEI)中的一项或者多项。
具体的，终端可以在主链路(可以称为第二链路)上，通过第二模块(比如主电路)接收来自网络设备的第一信息和/或进行随机接入。其中第二链路对应第二频域资源，第二频域资源可以与WUR链路对应的第一频域资源相同或者不同。在终端接收来自网络设备的第一信息和/或进行随机接入时，终端可以处于第二状态或第二模式，换言之，终端可以在第二状态或者第二模式向接收来自网络设备的第一信息和/或进行随机接入，其中进行随机接入可以包括终端向网络设备发送前导码等。
本申请实施例中，第一时域资源可以理解为某段包含N个预设长度的第一时间单元的时间资源。第一时域资源可以命名为WUR帧或者唤醒帧或者其他名称，不予限制。本申请以第一时域资源为WUR帧为例进行描述，在此统一说明。
其中一个WUR帧中可以包括N个预设长度的第一时间单元，不同WUR帧包括的第一时间单元的长度可以相同或不同，N为大于或等于1的整数(或者N为正整数)，第一时间单元可以用于传输唤醒信号。步骤602可以替换描述为网络设备在WUR帧中的至少一个第一时间单元上向终端发送唤醒信号，终端在WUR帧中的至少一个第一时间单元上接收来自网络设备的唤醒信号。第一时域资源除用于传输唤醒信号之外，还可以用于传输其他信号，比如同步信号、以及其他在第二链路(或主链路)上传输的信号。
例如，假设第一时域资源为WUR帧，如图7c、图7e、图9b以及图9d所示，图中黑色框表示用于传输主链路上的信号的时域资源。一种实施例中，WUR帧格式可以如图7c中的(1)、图9b中的(1)所示，WUR帧包括唤醒信号的时域资源， WUR帧不包括黑色框对应的时域资源，此时WUR帧可以用于传输唤醒信号，不可以用于传输主链路上的信号。又一种实施例中，如图7e中的(1)以及图9d中的(1)所示，WUR帧包括同步信号的时域资源以及唤醒信号的时域资源，WUR帧不包括黑色框对应的时域资源，此时WUR帧可以用于传输同步信号以及唤醒信号，不可以用于传输主链路上的信号。另一种实施例中，WUR帧格式还可以如图7c中的(2)以及图9b中的(2)，WUR帧包括唤醒信号的时域资源以及图中黑色框对应的时域资源，此时WUR帧不仅可以用于传输唤醒信号，还可以用于传输主链路上的信号。再一种实施例中，如图7e中的(2)以及图9d中的(2)所示，WUR帧包括同步信号的时域资源、唤醒信号的时域资源以及图中黑色框对应的时域资源，此时WUR帧不仅可以用于传输同步信号和唤醒信号，还可以用于传输主链路上的信号。应理解，图7c、图7e、图9b以及图9d为示例性附图，本申请不限定图7c、图7e、图9b以及图9d示出的WUR帧的数量、时域资源的长度等。
具体的，网络设备可以通过WUR链路向终端发送唤醒信号，终端可以通过WUR链路或第一模块接收来自网络设备的唤醒信号，此时终端处于第一状态或者第一模式，终端是在第一状态或者第一模式下，通过WUR链路或第一模块接收来自网络设备的唤醒信号。
本申请实施例中，第一时间单元可以命名为WUR时隙(WUR slot)或WUR时机(WUR occasion)或者调度单元等。第一时间单元可以包括多个符号(或者称为码片(chip))，即第一时间单元可以理解为包括多个时间连续的符号(或者chip)的时间段。一个符号可以对应一个编码比特，编码比特可以指对原始信息进行编码后得到的比特。WUR帧的长度、第一时间单元的长度可以预先配置，比如协议预先规定好。一个WUR帧中第一时间单元的数量N可以由网络设备确定，并由网络设备指示/配置给终端。或者一个WUR帧中第一时间单元的数量N可以在协议中预先规定好。第一时间单元的边界位置可以根据同步信号的时域位置确定，第一时间单元的长度可以与同步信号的时域资源的长度相同，也可以是不同的，比如同步信号的时域资源的长度小于第一时间单元的长度。
基于图6所示方法，可以定义好用于传输唤醒信号的时域资源以及该时域资源的边界位置，以便终端获知唤醒信号的起始位置以及都在哪些时域位置上检测/接收唤醒信号，减少终端解码与寻呼相关的信息(比如寻呼消息)的次数(即仅在第一时间单元的边界位置才尝试解码，而非在任意符号位置都尝试解码)，进而降低终端的虚警概率，避免现有方式中终端在任意符号位置都尝试解码带来的虚警概率较大的问题。
假设第一时域资源为WUR帧，具体的，WUR帧以及第一时间单元的设计如下：
一种可能的设计中，WUR帧用于传输唤醒信号，WUR帧可以包括相邻同步信号之间的时域资源(或者称为时间资源等)，WUR帧的长度等于或者小于相邻同步信号之间的时域资源长度。比如将同步信号的结束位置与相邻的下一同步信号的起始位置之间的全部时域资源或部分时域资源作为一个WUR帧，或者将同步信号的结束位置与相邻的下一同步信号的起始位置之间的部分或者全部时域资源划分为多个WUR 帧。这种可能的设计中，WUR帧不包括同步信号的时域资源，该WUR帧包括一个或者多个第一时间单元，一个第一时间单元可以用于传输一个唤醒信号，即一个唤醒信号占用一个第一时间单元，或者多个第一时间单元可以用于传输一个唤醒信号，即一个唤醒信号占用多个第一时间单元。
假设第一时间单元为WUR slot，一个WUR slot用于传输一个唤醒信号。例如，如图7a所示，将同步信号1与同步信号2之间的全部时域资源作为一个WUR帧，一个WUR帧包括四个WUR slot(如图7a中虚线框所示)。又例如，如图7b所示，将同步信号1与同步信号2之间的全部时域资源划分为多个WUR帧，一个WUR帧包括两个WUR slot(如图7b中虚线框所示)。再例如，如图7c中的(1)所示，将同步信号1与同步信号2之间的部分时域资源(除黑色框之外的时域资源)作为一个WUR帧，一个WUR帧中可以包括三个WUR slot(如图7c中的(1)中虚线框所示)。
又一种可能的设计中，WUR帧用于传输一个同步信号以及唤醒信号，比如，该可能的设计中，WUR帧的开始部分用于传输同步信号，同步信号之后用于传输唤醒信号。WUR帧可以包括同步信号所用的时域资源、以及该同步信号与相邻的下一同步信号之间的时域资源，WUR帧的长度大于相邻同步信号之间的时域资源长度。比如将同步信号的起始位置与相邻的下一同步信号的起始位置之间的时域资源作为WUR帧。这种可能的设计中，WUR帧可以包括同步信号的时域资源以及一个或者多个第一时间单元，一个第一时间单元可以用于传输一个唤醒信号，即一个唤醒信号占用一个第一时间单元，或者多个第一时间单元可以用于传输一个唤醒信号，即一个唤醒信号占用多个第一时间单元。
假设第一时间单元为WUR slot，一个WUR slot用于传输一个唤醒信号。例如如图7d所示，将同步信号1的时域资源、以及同步信号1与同步信号2之间的时域资源作为一个WUR帧，一个WUR帧包括用于同步信号传输的时域资源以及四个WUR slot(如图7d中虚线框所示)。又例如，如图7e中的(1)所示，同步信号1的时域资源、以及同步信号1与同步信号2之间的部分时域资源(除黑色框之外的时域资源)作为一个WUR帧，一个WUR帧包括用于同步信号传输的时域资源以及三个WUR slot(如图7e中的(1)中虚线框所示)。
再一种可能的设计中，WUR帧用于传输多个(两个或两个以上)同步信号以及唤醒信号，比如，该可能的设计中，WUR帧的开始部分用于传输一个同步信号，该同步信号之后用于传输唤醒信号，唤醒信号之后可以再传输同步信号，同步信号之后可以再传输唤醒信号等。
假设第一时间单元为WUR slot，一个WUR slot用于传输一个唤醒信号。例如如图7f所示，将同步信号1的起始位置与同步信号3的起始位置之间的时域资源看做为一个WUR帧，该WUR帧包括两个同步信号1和同步信号2对应的时域资源以及8个WUR slot(如图7f中虚线框所示)，其中前4个WUR slot位于同步信号1和同步信号2之间的时域资源，后4个WUR slot为同步信号2之后、同步信号3之前的时域资源。
需要说明的是，在WUR帧为相邻同步信号之间的部分时域资源的情况下，WUR 帧与该相邻同步信号之间的其他时域资源可以支持WUR链路与主链路采用时分复用(time division multiplexing，TDM)传输信号。例如，图7c中的(1)和图7e中的(1)中同步信号之间的WUR帧可以用于传输唤醒信号，而同步信号之间的其他时域资源(黑色框对应的时域资源)可以用于传输其他信号，该其他信号不同于唤醒信号，该其他信号可以在主链路上传输，比如该其他信号可以为网络设备发送的第一信号，再比如该其他信号可以为其他终端向网络设备发送的第二信号。
应理解，本申请实施例所述的WUR帧不限于用于传输唤醒信号，或者用于传输同步信号和唤醒信号，还可以用于传输其他信号(比如第一信号、第二信号等)，比如还可以用于传输主链路对应的信号，即WUR链路与主链路上传输的信号所使用的时域资源均包括在WUR帧，只不过在TDM场景下，用于传输主链路上的信号的时域资源不可用于传输WUR链路上的信号(唤醒信号，或者同步信号和唤醒信号等)。例如，本申请不限于如图7c中的(1)和图7e中的(1)所示，WUR帧不包括黑色框对应的时域资源，可替换的，还可以设计为WUR帧包括如图7c中的(2)和图7e中的(2)所示黑色框对应的时域资源，只不过黑色框对应的时域资源不被WUR链路所利用，而是被用于在主链路上传输第一信号、第二信号等。
其中，第一信号包括以下至少一项：同步信号块(synchronization signal block，SSB)、物理下行控制信道(physical downlink control channel，PDCCH)、物理下行共享信道(physical downlink shared channel，PDSCH)、信道状态信息参考信号(channel state information reference signal，CSI-RS)、相位跟踪参考信号(phase tracking reference signal，PT-RS)、定位参考信号(positioning reference signals，PRS)、解调参考信号(demodulation reference signal，DMRS)。其中，所述第二信号包括以下至少一项：DMRS、物理上行共享信道(physical uplink shared channel，PUSCH)、物理上行控制信道(physical uplink control channel，PUCCH)、探测参考信号(sounding reference signal，SRS)。
应理解，本申请实施例中，一种可能的设计中，每个周期内或者不同周期内的WUR帧的格式可以设置为相同的，一个周期内可以包括一个或者多个WUR帧，或者一个WUR帧包括一个或者多个周期等，不予限制。需要解释的是，本申请所述的周期可以指同步信号的发送周期，比如同步信号的时域资源的起始位置与相邻的下一同步信号的时域资源的起始位置之间的时间段可以称为一个周期。该周期可以预先配置或者协议规定好。例如上述图7a-图7f所示附图中各个WUR帧的帧格式是相同的。
应理解，本申请所述的WUR帧的帧格式可以包括WUR帧的长度、WUR帧包括的第一时间单元的数量、WUR帧包括的第一时间单元的长度、WUR帧包括的同步信号的时域资源的长度、WUR帧包括的时间单元上可承载的信号的类型等等。本申请所述的WUR帧包括信号(同步信号、唤醒信号等)可以指WUR帧包括该信号的传输资源，或者WUR帧包括可用于传输该信号的时域资源。
再一种可能的设计中，不同WUR帧的格式可以设置为不相同，比如两个WUR帧，这两个WUR帧的长度可以是相同的，但是这两个WUR帧包括的时间单元上可承载的信号是不同的，其中一个WUR帧可以包括同步信号的时域资源以及唤醒信号 的时域资源，该WUR帧可以用于承载/传输至少一个同步信号和至少一个唤醒信号，而另一个WUR帧不包括同步信号的时域资源，而包括唤醒信号的时域资源，该WUR帧用于传输至少一个唤醒信号。
假设第一时间单元为WUR slot，一个WUR slot用于传输一个唤醒信号。例如如图7g所示，将从同步信号1的起始位置至同步信号2之间的时域资源分为两个WUR帧：WUR帧1和WUR帧2，WUR帧1包括用于同步信号1传输的时域资源以及三个WUR slot(如图7d中虚线框所示)，同步信号的时域资源的长度等于WUR slot的长度。WUR帧2包括用于传输唤醒信号的四个WUR slot，每个WUR帧的长度是相同的。
应理解，图7a-图7g仅为示例性的WUR帧格式图，仅示出了几个周期内的WUR帧，图7a-图7g中包括的同步信号、WUR帧的数量、WUR帧包括的时间单元的数量不受限制，比如图7a-图7g可以包括更多的同步信号、WUR帧、一个WUR帧可包括更多的时间单元等。
此外，图7a-图7g所示的WUR帧格式中一个唤醒信号占用一个第一时间单元，不同于图7a-图7g所示的WUR帧格式，还可以设计一个唤醒信号占用多个第一时间单元，该场景下的第一时间单元可以命名为调度单元，一个调度单元可以包括多个符号(或者码片)，一个符号对应一个编码比特，即一个符号可以用于承载一个编码比特。例如，如图7h所示，一个WUR帧包括10个调度单元(如图7h中长方形虚线框所示)，其中唤醒信号可以占用5个调度单元。应理解，图7h所示WUR帧格式中第一时间单元的设计可以适用于其他WUR帧的其他设计格式(比如图7a-图7g所示格式)，即图7a-图7g所示格式中的第一时间单元(比如WUR slot)可以不仅限于图中所示，还可以替换设计为如图7h所示，在此不再一一示出。
本申请实施例中，第一时间单元与同步信号的时域位置之间存在一定的时域位置关系，第一时间单元的边界位置可以根据同步信号的时域位置确定。
一种可能的设计中，第一时间单元的边界位置根据同步信号的起始位置确定，比如假设第一时间单元为第一时域资源内的第一个时间单元，第一时间单元的起始位置为同步信号的起始位置之后、距离同步信号的起始位置第一预设间隔的位置。其中第一时间单元的长度可以等于第一预设间隔。第一预设间隔可以预先设置。
假设第一时间单元为WUR slot，例如，如图8a所示，WUR帧包括四个WUR slot，WUR帧中的第一个WUR slot为WUR slot1，WUR slot1的起始位置为同步信号1的起始位置之后间隔1的位置。又例如，如图8b所示，每个WUR帧包括四个WUR slot，其中WUR1帧中的第一个WUR slot用于同步信号1传输，后三个WUR slot用于唤醒信号传输，同步信号1的起始位置与WUR帧1中的第二个WUR slot的起始位置之间的间隔为一个WUR slot。WUR帧2中的四个WUR slot均可以用于唤醒信号传输，WUR帧2中不存在同步信号，不用于传输同步信号。
又一种可能的设计中，第一时间单元的边界位置根据同步信号的结束位置确定，比如假设第一时间单元为第一时域资源内的第一个时间单元，第一时间单元的起始位置为同步信号的结束位置，或者，第一时间单元的起始位置为同步信号的结束位置之后、距离同步信号的结束位置第二预设间隔的位置，比如第一时间单元的长度可以等 于同步信号的长度和第二预设间隔的长度之和。其中第二预设间隔可以预先设置。
假设第一时间单元为WUR slot，例如，如图7a所示，第一个WUR slot为WUR slot1，WUR slot1的起始位置为同步信号1的结束位置，即WUR slot1的起始位置与同步信号1的结束位置重叠。又例如，如图8a所示，WUR帧包括四个WUR slot，WUR帧中的第一个WUR slot为WUR slot1，WUR slot1的起始位置为同步信号1的结束位置之后距离间隔2的位置。再例如，如图8b所示，每个WUR帧包括四个WUR slot，其中WUR1帧中的第一个WUR slot用于同步信号1传输，后三个WUR slot用于唤醒信号传输，同步信号1的结束位置与WUR帧1中第二个WUR slot的起始位置之间间隔2，间隔2和同步信号1的时长之和等于一个WUR slot的长度。WUR帧2中的四个WUR slot均可以用于唤醒信号传输，WUR帧2中不存在同步信号，不用于传输同步。
本申请实施例中，第一时域资源与同步信号的时域位置也存在一定的位置关系。一种可能的设计中，第一时域资源的起始位置为同步信号的结束位置，即第一时域资源的起始位置与同步信号的结束位置重叠。假设第一时域资源为WUR帧，例如，如图7a所示，图7a中从左边开始的第一个WUR帧的起始位置为同步信号1的结束位置。或者，第一时域资源的起始位置为同步信号的结束位置之后、距离同步信号的结束位置第三预设间隔的位置。其中第三预设间隔可以预先设置。假设第一时域资源为WUR帧，例如，如图8a所示，图8a中从左边开始的第一个WUR帧的起始位置为同步信号1的结束位置之后间隔2的位置，第二个WUR帧的起始位置为同步信号2的结束位置之后间隔2的位置。
又一种可能的设计中，第一时域资源的结束位置为同步信号相邻的下一同步信号的起始位置。假设第一时域资源为WUR帧，例如，如图7a所示，图7a中的第一个WUR帧的结束位置为同步信号2的起始位置。或者，第一时域资源的结束位置为同步信号相邻的下一同步信号之前、距离同步信号相邻的下一同步信号的起始位置第四预设间隔的位置。假设第一时域资源为WUR帧，例如，如图8c所示，图8c中从左边开始的第一个WUR帧的结束位置为同步信号2的起始位置之前间隔3的位置，第二个WUR帧的结束位置为同步信号3的起始位置之前间隔3的位置。
应理解，上述仅示出了图7a、图8a以及图8c所示WUR帧格式下第一时域资源与同步信号的时域位置之间的位置关系、第一时间单元与同步信号的时域位置之间的关系。类似的，其他WUR帧格式(比如图7b-图7h所示格式)下第一时域资源与同步信号的时域位置之间的位置关系、第一时间单元与同步信号的时域位置之间的位置关系可以不仅限于图中所示，也可以参照图7a、图8a以及图8c所示的位置关系来设置，在此不再一一示出。
本申请实施例中，唤醒信号可以至少用于指示寻呼相关的信息，比如唤醒信号可以用于指示需要接收寻呼的一个或者多个终端。比如唤醒信号可以包括需要接收寻呼的终端的标识或需要接收寻呼的终端所在组的组标识等。此外，唤醒信号还可以包括系统消息等其他信息。
可选的，终端可以根据本地时钟确定唤醒信号占用的第一时间单元的位置，即终端可以根据第一时间单元距离同步信号的远近推算出唤醒信号占用的第一时间单元的 位置。例如，假设每个第一时间单元包含40个符号，每个符号长度为4us，则终端可以根据本地时钟计算时间，每隔160us则认为到了下一个第一时间单元的位置。或者唤醒信号还可以携带/包含指示信息，比如可以在该唤醒信号的开始位置上携带/包含该指示信息。该指示信息可以用于指示唤醒信号所在的/所占用的第一时间单元的索引值，或者该指示信息用于指示唤醒信号所在的/所占用的起始时间单元的索引值，该起始时间单元可以指唤醒信号所占用的第一时间单元中的第一个第一时间单元。如此，便于终端根据该指示信息确定/定位唤醒信号在WUR帧中的位置，提高唤醒信号检测的准确性。
本申请实施例中，时间单元的索引值(比如第一时间单元的索引值或者起始时间单元的索引值)可以指该时间单元在一个WUR帧包括的N个第一时间单元中的编号。可选的，按照N个第一时间单元的时间先后顺序进行顺序编号，N个第一时间单元的编号可以是0～(N-1)或者可以是1～N。比如如图7h所示，一个WUR帧中包括10个调度单元：调度单元0-调度单元9，其中唤醒信号占用调度单元5-调度单元9，此时唤醒信号中可以携带起始时间单元：调度单元5的索引值5，终端根据该索引值5以及唤醒信号对应的编码比特的数量(即唤醒信号的长度)获知该唤醒信号位于调度单元5-调度单元9，进而在调度单元5-调度单元9上检测/接收唤醒信号。应理解，唤醒信号对应的编码比特的数量(即唤醒信号的长度)可以是预先确定的，比如可以是网络设备预先通过主链路配置或者标准预定义的。
由上可知，本申请对WUR帧(即用于传输唤醒信号的第一时域资源)格式进行设计，明确WUR帧中可以用于传输唤醒信号的时间单元的数量、用于传输唤醒信号的时间单元的边界位置与同步信号之间的位置关系等，以便终端根据同步信号完成时间同步后，能够准确定位出哪些时间单元上会传输有唤醒信号，进而在这些时间单元上进行唤醒信号的检测，避免虚警。
例如，假设一个WUR帧为相邻同步信号之间的全部时域资源，第一时间单元为WUR slot，一个WUR slot用于传输一个唤醒信号，如图8d所示，不会存在一个唤醒信号跨两个WUR slot传输的情况。因此在唤醒信号包括需要被唤醒的终端的标识时，假设小区内包括UE1和UE2，UE1的标识为AB，UE2的标识为BC，如果基站要唤醒该小区中的UE1，则基站会发送唤醒信号“AB”。对于UE1、UE2而言可以按照本申请所示的WUR帧格式，以一个WUR slot(比如如图8d中第二个WUR帧中的WUR slot2)的边界为起点开始检测接收到的唤醒信号直至该WUR slot内的编码比特全部检测完成，根据检测结果确定标识是否是自己的，若是，则被唤醒。UE1、UE2不会从WUR slot的中间位置(即图8d中编码比特B的起始位置)开始连续检测得到两个编码比特“BX”，也不会在有噪声干扰时将第二个编码比特“X”误认为/误检测成编码比特C，导致UE2被唤醒。
上述描述了WUR帧可以用于传输唤醒信号。可选的，对于不同终端，该终端可以位于同一小区或者不同小区，该终端可以被配置不同的接收唤醒信号的时间窗(window)，以保证同一小区中不同终端的时间窗是错开的/不重叠的，或者不同小区内的不同终端的时间窗是错开的/是重叠的。该时间窗可以指终端接收唤醒信号的时间段，时间窗可以是一个WUR帧中的部分资源(比如部分第一时间单元)或者时 间窗是一个或者多个WUR帧。
应理解，本申请实施例中，不同终端接收唤醒信号的时间窗可以是相互独立、不重叠的。或者不同终端接收唤醒信号的时间窗可以是重叠的。
例如，以不同终端分别位于小区1、小区2为例，为小区1中的终端配置的接收唤醒信号的时间窗为WUR帧1-WUR帧3中的WUR slot2-WUR slot4，小区1中的终端可以在WUR帧1-WUR帧3中的WUR slot2-WUR slot4上接收唤醒信号。为小区2中的终端配置的接收唤醒信号的时间窗可以为WUR帧6-WUR帧9，即时间窗包括WUR帧6-WUR帧9中的全部WUR slot，小区2中的终端可以在WUR帧6-WUR帧9中的全部WUR slot上接收唤醒信号。此时，位于小区1的终端的时间窗与位于小区2的终端的时间窗是不重叠的，相互独立的。
又例如，对于位于同一小区终端中的UE1、UE2和UE3，为UE1配置时间窗“WUR帧0-WUR帧3”，为UE2配置时间窗“WUR帧2-WUR帧5”，为UE3配置时间窗“WUR帧4-WUR帧7”，此时UE1、UE2的时间窗是重叠的，UE2和UE3的时间窗是重叠的，UE1和UE3的时间窗是不重叠的，实现同一小区中不同终端的时间窗相互重叠或者相互独立。
示例性的，可以由网络设备为终端配置接收唤醒信号的时间窗。比如网络设备在终端处于连接态时，通过主链路向终端发送第一配置信息，第一配置信息可以用于指示终端接收唤醒信号的时间窗，比如第一配置信息可以包括终端接收唤醒信号的WUR帧的帧号(或者称为索引值)和/或WUR帧中的时间单元的索引值等。
本申请实施例中，终端可以通过如下两种工作方式实现在时间窗内接收唤醒信号：方式一、使用唤醒电路持续接收信号，即唤醒电路始终在接收信号。当定义了WUR帧以及WUR帧包括的第一时间单元之后，唤醒电路始终通过同步信号维持时间同步，但仅在时间窗内做唤醒信号的识别/检测。方式二：使用唤醒电路间断性接收信号，即终端仅在时间窗附近的位置上打开/开启唤醒电路接收信号，其他时间关闭唤醒电路，以进一步降低终端的功率消耗。
其中，为了使能上述方式二，WUR链路需要提供系统定时，其原因如下：终端在WUR链路上周期性间断性地接收唤醒信号，比如每隔Q个同步信号周期在WUR链路上接收一次，Q为大于1的整数，则终端需要知道自己接收到的唤醒信号位于Q个周期中的第几个周期，否则，终端采用上述方式二时，一段时间不接收唤醒信号后，由于本地时钟精度较低，当终端再次打开唤醒电路接收唤醒信号时，无法确切的知道到了Q个周期中的第几个周期，是否到了自己需要接收唤醒信号的时间窗。因此，终端获取到第一配置信息之后，终端可以获取系统定时，根据系统定时结果以及第一配置信息确定自己需要接收唤醒信号的时间窗的时间位置，在时间窗内接收唤醒信号。
本申请实施例所述的系统定时可以指终端确定自己接到到的信号(比如唤醒信号)为一个大周期中的第几个WUR帧(即第一时域资源)。该大周期可以包括多个WUR帧，该大周期可以用WUR帧的索引范围来表示，是比如大周期可以是[起始WUR帧的索引值，结束WUR帧的索引值]或者起始WUR帧的索引值～结束WUR帧的索引值，该大周期的长度等于起始WUR帧与结束WUR帧之间的长度，该大周期 的长度可以等于该大周期内包括的WUR帧的数量与一个WUR帧的长度的乘积。例如，WUR帧的索引值的取值范围为0～1023时，一个大周期的长度即为1024个WUR帧的长度。具体的，该大周期的命名、长度可以根据需要设置，不予限制。系统定时结果可以包括当前接收收到的信号所处的WUR帧的索引值/帧号，根据系统定时结果以及第一配置信息，在时间窗内接收唤醒信号包括：若终端根据系统定时结果知道到了/即将到自己需要接收唤醒信号的时间窗(比如WUR帧)，则醒来在该时间窗内接收唤醒信号。
示例性的，终端可以获取定时索引，进一步的根据定时索引确定系统定时。其中，定时索引可以指示第一时域资源(例如WUR帧)的索引值。以第一时域资源为WUR帧为例，一种可能的设计，定时索引包括WUR帧的索引值(或者称为WUR帧的帧号)，即定时索引直接指示WUR帧的索引值。又一种可能的设计中，定时索引可以包括用于计算得到WUR帧的索引值的参数，根据定时索引可以计算得到WUR帧的索引值，该可能的设计中，定时索引可以间接指示WUR帧的索引值。本申请中采用下述几种方式中任一方式获取定时索引：
方式一、定时索引根据第一信息确定，比如第一信息包括定时索引。
该方式一中，第一信息可以携带在同步信号中。比如同步信号对应的同步序列后面跟着若干比特的第一信息，该第一信息指示定时索引，即同步信号中，除了用于同步功能的序列外，还包含用于终端确定系统定时的指示信息(比如第一信息)。在WUR帧不包括同步信号的情况下，该指示信息可以用于指示同步信号之后的WUR帧是哪个WUR帧。在WUR帧包括同步信号的情况下，该指示信息可以用于指示该同步信号所在的WUR帧是哪个WUR帧。
例如，如图9a或图9b中的(1)所示，WUR帧包括唤醒信号，不包括同步信号，WUR帧在同步信号之后，此时可以通过在同步信号中携带定时索引＝n，指示该同步信号后的WUR帧为WUR帧n，在同步信号中携带定时索引＝n+1指示该同步信号之后的WUR帧为WUR帧n+1，在同步信号中携带定时索引＝n+2指示同步信号之后的WUR帧为WUR帧n+2。又例如，如图9c或图9d中的(1)所示，WUR帧中包括同步信号以及唤醒信号，通过在同步信号中携带定时索引＝n，指示该同步信号当前所在的WUR帧为WUR帧n，在同步信号中携带定时索引＝n+1指示该同步信号当前所在的WUR帧为WUR帧n+1，在同步信号中携带定时索引＝n+2指示同步信号当前所在的WUR帧为WUR帧n+2。
应理解，本申请不限于WUR帧包括的时域资源，WUR帧除包括用于传输WUR链路上的信号的时域资源之外，WUR帧还可以包括用于传输其他链路(如主链路)上的信号的时域资源。例如，WUR帧不限于图9b中的(1)和图9d中的(1)所示不包括黑色框对应的时域资源，可替换的，还可以设计为WUR帧包括用于在其他链路上传输的信号的时域资源，如图9b中的(2)和图9d中的(2)所示，WUR帧除包括唤醒信号的时域资源之外，还可以包括黑色框对应的时域资源，只不过黑色框对应的时域资源不被WUR链路所利用，而是被利用在主链路上传输信号(比如本申请所述的第一信号和第二信号等)。
应理解，图9a-图9d仅为示例性的WUR帧格式图，仅示出了几个周期内的 WUR帧，图9a-图9d中包括的同步信号、WUR帧的数量、WUR帧包括的时间单元的数量不受限制，如图9a-图9d可以包括更多的同步信号、WUR帧、一个WUR帧可以包括更多的时间单元等。
方式二、定时索引与同步信号的同步序列之间存在映射关系，定时索引根据映射关系以及同步信号的同步序列确定。终端接收到同步信号后，可以通过盲检的方式确定同步信号使用的同步序列是哪个，再以同步信号的同步序列为索引查找该映射关系，找到与该同步序列对应的定时索引，进一步根据定时索引得到WUR帧的索引值。比如在WUR帧不包括同步信号的情况下，根据查找映射关系得到的定时索引可以确定同步信号之后的WUR帧是哪个WUR帧。在WUR帧包括同步信号的情况下，根据查找关系确定的定时索引可以确定同步信号当前所在的WUR帧是哪个WUR帧。
其中该映射关系可以预先设置，比如在标准中预定义或者由网络设备预先设置等。定时索引与同步信号的同步序列之间的映射关系可以是列表形式，也可以是数组形式，不限制。
以定时索引与同步信号的同步序列之间的映射关系为列表形式为例，下表一示出了该映射关系，从表一可知存在0-15共十五种同步序列，一个同步序列对应一个定时索引，共存在16个定时索引，定时索引取值为0～15。假设终端接收到的同步信号的同步序列为同步序列1，则终端可以以同步序列1为索引查表一得到定时索引＝1，则根据该定时索引＝1确定该同步信号之后的WUR帧为WUR帧1或者该同步信号当前所在的WUR帧为WUR1。应理解，表一仅为示例性表格，本申请所示定时索引与同步信号的同步序列之间的映射关系不限于表一所示同步序列以及定时索引，还可以包括其他定时序列以及定时索引等。
表一
同步序列 定时索引
同步序列0 定时索引＝0
同步序列1 定时索引＝1
同步序列2 定时索引＝2
…… ……
同步序列15 定时索引＝15
方式三、定时索引根据第二信息和同步信号的同步序列确定。进一步的根据定时索引得到WUR帧的索引值。比如在WUR帧不包括同步信号的情况下，根据查找映射关系得到的定时索引可以确定同步信号之后的WUR帧是哪个WUR帧。在WUR帧包括同步信号的情况下，根据查找关系确定的定时索引可以确定同步信号当前所在的WUR帧是哪个WUR帧。
该方式三可以理解为上述方式一和方式二的结合，可以理解为通过携带在同步信号中的指示信息以及同步信号的同步序列联合指示定时索引。比如，定时索引根据第二信息和同步信号的同步序列确定可以包括：定时索引由M1个信息比特以及M2个信息比特确定；其中，M1个信息比特携带在同步信号中，第二信息包括M1个信息比特，M2个信息比特与同步信号的同步序列之间存在映射关系，M2个信息比特根 据同步信号的同步序列确定，M1、M2为正整数，M1和M2的具体取值可以预先配置，比如协议预先定好或者由网络设备配置等。
例如，假设定时索引的取值为0～31，则这32个定时索引若所采用方式一所示方式则需要用6比特来指示，比如定时索引＝4，则需要6个比特“000100”来指示，又比如定时索引＝15，则需要6个比特“001111”来指示。而方式三中，这6个比特中的5个比特携带在同步信号中，即第二信息包括5个比特，M1＝5，而剩余的1个比特的取值可以通过两种同步序列表示，即M2＝1，比如定时索引＝4，可以将指示该定时索引的6个比特“000100”中的低五个比特“00100”携带在同步信号中，而剩余的高位比特“0”可以用两个同步序列中一个同步序列指示，比如两个同步序列中一个同步序列指示0，另一个同步序列指示1，进而将同步序列中的五个比特和同步序列指示的一个比特组合在一起指示定时索引。或者将指示该定时索引的6个比特“000100”中的低四个比特“0100”携带在同步信号中(即第二信息包括4个比特，M1＝4)，而剩余的高位比特“00”可以用四个同步序列中的一个同步序列指示，即M2＝2，比如四个同步序列分别对应指示00、01、10、11，可以用第一个同步序列指示剩余的高位比特“00”，进而将同步序列中的四个比特和同步序列指示的两个比特组合在一起指示定时索引。
上述以将定时索引的低比特位携带在同步信号中、高比特位与同步信号的同步序列成映射关系来组合指示定时索引。可选的，还可以将定时索引的高比特位携带在同步信号中、低比特位与同步信号的同步序列成映射关系来组合指示定时索引。比如定时索引＝4，可以将指示该定时索引的6个比特“000100”中的高五个比特“00010”携带在同步信号中，而剩余的高位比特“0”可以用两个同步序列中一个同步序列指示，比如两个同步序列中一个同步序列指示0，另一个同步序列指示1，进而将同步序列中的五个比特和同步序列指示的一个比特组合在一起指示定时索引。或者将指示该定时索引的6个比特“000100”中的高四个比特“0001”携带在同步信号中，而剩余的低比特“00”可以用四个同步序列中的一个同步序列指示，比如四个同步序列分别对应指示00、01、10、11，可以用第一个同步序列指示剩余的低位比特“00”，进而将同步序列中的四个比特和同步序列指示的两个比特组合在一起指示定时索引。
如此，终端可以定时索引以及第一配置信息确定时间窗，在时间窗之前提前醒来，为在时间窗内接收唤醒信号做准备，保证唤醒信号的正常接收。例如，网络设备指示UE在定时索引＝10的WUR帧内接收唤醒信号。UE在某次定时索引＝10的WUR帧内接收完唤醒信号后，UE可以停止通过唤醒电路接收信号，进入休眠状态。但是UE的本地时钟仍在运行，UE可以根据本地时钟，判断定时索引＝10的WUR帧出现的位置。由于本地时钟精度有限，UE仅能判断定时索引＝10的WUR帧的大致位置。此时UE可以在定时索引＝10的WUR帧出现的大致位置之前醒来，并接收同步信号。根据新接收到同步信号指示的定时索引，UE可以知道下一个定时索引＝10的WUR帧出现的确切位置，并在定时索引＝10的WUR帧中接收唤醒信号，进一步检测接收的唤醒信号是否有与自己相关。
可选的，在图6所示方法中，基于下述两个原因，网络设备与终端之间的WUR链路支持多种数据率，即可以在WUR链路上采用多种数据率来传输唤醒信号。
原因一：终端和网络设备之间的信道状态有好有坏。当终端与网络设备之间的信道状态较差，比如较低的信噪比(signal noise ratio，SNR)时，可以通过降低唤醒信号的数据率的方法提升WUR链路的鲁棒性，由于降低唤醒信号的数据率等效为增加唤醒信号占用的时间单元的长度，可获得更多时域分集，因此降低唤醒信号的数据率可以提升WUR链路的鲁棒性。但终端与网络设备之间的信道状态较好时，可以无需降低唤醒信号的数据率，而是采用预先配置的或者较高的数据率等。
原因二：每个终端的唤醒信号到达时间是随机的，在一段时间内，WUR链路需要发送的唤醒信号的个数可能有多有少。为了保证小区边缘的终端也能正确接收唤醒信号，可选的，配置唤醒信号使用较低的数据率。但是较低的数据率的唤醒信号占用空口资源(比如时域资源)较多，当需要发送的唤醒信号个数较多时，采用低数据率可能导致系统容量不足，此时可以考虑使用高数据率方式发送唤醒信号，提高短时间内的系统容量，而当发送的唤醒信号的个数不多/较少时，采用较低的数据率等，保证小区边缘的终端也能够正确接收唤醒信号。
本申请实施例中，数据率可以指WUR上传输的信号(比如唤醒信号)携带的原始信息数据量与该信号对应的编码比特的数量之间的比值。假设某个唤醒信号的数据量为20bit，如果该信号被编码为40bit，则该唤醒信号的数据率为20/40＝0.5。如果该信号被编码为80bit，则该唤醒信号的数据率为20/80＝0.25。即对于同一原始信息，如果该原始信息对应的唤醒信号的数据率越低，唤醒信号对应的编码比特数量越多，反之，数据率越高，唤醒信号对应的编码比特数量越少。由于一个编码比特占用一个符号，多个符号组成一个WUR帧中的一个时间单元，则数据率越低，唤醒信号占用的时间单元的总长度越长，唤醒信号占用的时间单元的个数越多，反之，数据率越高，唤醒信号占用的时间单元的总长度越短，唤醒信号占用的时间单元的个数越少。以唤醒信号包括第一唤醒信号和第二唤醒信号为例，当第一唤醒信号的数据率低于第二唤醒信号的数据率时，第一唤醒信号占用的时间单元的总长度大于第二唤醒信号占用的时间单元的总长度，第一唤醒信号占用的时间单元的数量大于第二唤醒信号占用的时间单元的数量。应理解，本申请所述的唤醒信号占用的总时间单元的长度可以理解为唤醒信号的长度。
一种可能的设计中，唤醒信号的数据率根据同步信号而定，比如可以通过同步信号的长度指示该同步信号之后的WUR帧内唤醒信号的数据率。同步信号的长度越短，该同步信号之后的WUR帧内的唤醒信号的数据率越高，唤醒信号的长度越长，反之，同步信号的长度越长，该同步信号之后的WUR帧内的唤醒信号的数据率越低，唤醒信号的长度越短。
如图10a所示，同步信号1的长度小于同步信号2的长度，同步信号1之后、同步信号2之前的唤醒信号的长度小于同步信号2之后的唤醒信号的长度，同步信号1之后、同步信号2前的唤醒信号为高数据率的唤醒信号，同步信号2后的唤醒信号为低数据率的唤醒信号。
本申请实施例中，唤醒信号的长度可以由该唤醒信号被编码后的编码比特的数量来表征，比如唤醒信号的长度可以等于唤醒信号的编码比特的数量。唤醒信号的编码比特的数量越多，唤醒信号的长度越长，反之，唤醒信号的编码比特的数量越少，唤 醒信号越短。
又一种可能的设计中，可以在同步信号中携带指示信息，由该指示信息可以称为数据率指示信息，该指示信息可以指示同步信号之后的WUR帧内的唤醒信号的数据率。应理解，该可能的设计中，每个周期的同步信号的长度可以是相同的。
比如如图10b所示，同步信号1内携带指示信息1，指示信息1指示同步信号1之后的唤醒信号的数据率为高数据率。同步信号2内携带指示信息2，指示信息2指示同步信号2之后的唤醒信号的数据率为低数据率。此外，同步信号1的长度与同步信号2的长度相同。
由于不同数据率的唤醒信号的长度不同，为了满足上述的WUR帧格式要求，一种可能的设计中，在唤醒信号占用一个第一时间单元的情况下，可以根据唤醒信号的长度设计第一时间单元的长度，如果WUR帧中唤醒信号的数据率较高，则设计该WUR帧中第一时间单元的长度较短，如果WUR帧中唤醒信号的数据率较低，则设计该WUR帧中第一时间单元的长度较长，即不用数据率的WUR帧内的时间长度是不同的。
假设第一时间单元为WUR slot，例如，如图10c所示，同步信号1的长度小于同步信号2的长度，从图10c中可以看到，同步信号1之后、同步信号2前的唤醒信号为高数据率的唤醒信号，同步信号1之后的WUR帧1内有N＝4个WUR slot，一个唤醒信号占用一个WUR slot。同步信号2后的唤醒信号为低数据率的唤醒信号，同步信号2之后的WUR帧2内有N＝2个WUR slot，一个唤醒信号占用一个WUR slot，WUR帧1内WUR slot的长度小于WUR帧2内WUR slot的长度。
该可能的设计中，不同周期的同步信号的长度是不同的，可以通过同步信号的长度不同来指示该同步信号之后的唤醒信号的数据率。但是，由于WUR帧中第一时间单元的边界位置根据同步信号的时域位置(比如起始位置和/或结束)确定，同步信号的长度不同可能会导致第一时间单元的边界位置的变化。第一时间单元的边界位置的变化会进一步导致终端无法确定各个第一时间单元边界的时间位置，从而导致终端无法正确的接收唤醒信号。为了避免第一时间单元的边界位置的变化，可以设计同步信号的起始位置与第一时间单元的起始位置之间的长度是固定不变的/等长的，以保证第一时间单元的边界位置是固定不变的。
例如，如图10d所示，当采用同步信号1时，同步信号1的结束位置与WUR帧中WUR slot1的起始位置之间有一个间隔。当采用同步信号2时，同步信号2的结束位置与WUR帧2中WUR slot1的起始位置之间没有间隔。此时同步信号1的长度加上间隔的长度等于同步信号2的长度，且将该长度结束位置作为WUR slot的边界位置，保证每个周期内WUR slot的边界位置是固定的。可选的，此时无论采用同步信号1还是采用同步信号2，每个同步信号占用的时域资源的长度是相同，比如可以为WUR帧1所包括的一个WUR slot的长度。这样可以令WUR链路的结构更加整齐，有利于网络设备规划信号传输的位置。
又一种可能的设计中，可以设置第一时间单元的长度为固定长度值，不同WUR帧包括的第一时间单元的长度是相同的，同一WUR帧内的多个第一时间单元的长度是相同的。高数量率的唤醒信号占用的时间单元的数量小于低数据率的唤醒信号占用 的时间单元的数量。
假设第一时间单元为WUR slot，如图10e所示，同步信号1对应高数据率，同步信号2对应低数据率。从图10e中可以看到，同步信号1后的唤醒信号为高数据率，同步信号1之后的WUR帧1内有N＝4个WUR slot，一个唤醒信号占用其中一个WUR slot。同步信号2后的唤醒信号为低数据率，同步信号2之后的WUR帧2内有N＝4个WUR slot，唤醒信号占用其中两个WUR slot：WUR slot2和WUR slot3。不同WUR帧内的WUR slot的长度是相同的，同步信号2之后的唤醒信号占用的WUR slot的数量大于同步信号1之后的唤醒信号占用的WUR slot的数量。
该可能的设计中，不同周期的同步信号的长度可以是相同的，也可以是不同的。当不同周期的同步信号的长度是不同时，可以设计同步信号的起始位置与第一时间单元的起始位置之间的长度是固定不变的/等长的，以保证第一时间单元的边界位置是固定不变的。例如，如图10f所示，当采用同步信号1时，同步信号1的结束位置与WUR帧中WUR slot1的起始位置之间有一个间隔。当采用同步信号2时，同步信号2的结束位置与WUR帧1中WUR slot1的起始位置之间没有间隔。此时同步信号1的长度加上间隔的长度等于同步信号2的长度，该长度结束位置为WUR slot的边界位置，保证每个周期内WUR slot的边界位置是固定的。
应理解，图10a-图10f仅为示例附图，仅示出了几个周期内的WUR帧，图10a-图10f中包括的同步信号、WUR帧的数量、WUR帧包括的时间单元的数量不受限制，比如图10a-图10f可以包括更多的同步信号、WUR帧、一个WUR帧可以包括更多的时间单元等。此外，图10a-图10f所示的WUR帧格式包括唤醒信号，不包括同步信号，不同于图10a-图10f所示的WUR帧格式，还可以将图10a-图10f所示的WUR帧替换设计为包括同步信号以及唤醒信号，在此不再一一示出。
可选的，本申请实施例中，为了提高资源利用率，可以配置/设计WUR链路对应的第一频域资源与主链路对应的第二频域资源相同，WUR链路对应的时域资源与主链路对应的时域资源不同，比如WUR链路对应上述第一时域资源(即WUR帧)，主链路对应第二时域资源，如此可以实现TDM传输，提高资源利用率。例如，如图7c、图7e以及图9b中所示，相邻同步信号之间的时域资源包括第一时域资源和第二时域资源，第一时域资源为用于传输唤醒信号的WUR帧，第二时域资源为图7c、图7e以及图9b中黑色框的所示的时域资源，第二时域资源可以用于在主链路上传输信号，以实现TDM传输。
在TDM传输场景下，为了降低WUR链路上的信号和主链路上的信号之间的相互干扰，可以设计/配置WUR链路上的信号和主链路上的信号时间对齐。为了实现WUR链路上的信号和主链路上的信号的时间对齐，在设计WUR链路上的WUR帧的时候，配置WUR帧中包括的第一时间单元的长度大于主链路上帧中的时隙的长度，比如可以设置第一时间单元的长度为主链路对应的第二时域资源内所包括的时隙的长度的整数倍。如此可以保证每个第一时间单元的边界一定是时隙边界，所以边界是对齐的。进而实现在边界对齐的情况下，每次发送一个第一时间单元，网络设备只需要保证和该第一时间单元重合的时隙内不发送信号(比如NR信号)即可，避免在边界不对齐的情况下，第一时间单元上传输的信号与时隙上传输的信号可能会互相影 响，影响正常通信的问题。
例如，以NR系统为例，主链路上传输的帧内包括多个时隙(slot)，每个slot包含14或12个symbol。WUR链路中，无论是同步信号还是与寻呼相关的唤醒信号，其携带的编码比特的数量为大于14或12个编码比特，由于一个编码比特对应一个符号，因此唤醒信号的长度通常大于14或12个symbol。所以，WUR链路上的WUR信号(比如同步信号或者唤醒信号)的长度可以设置为比主链路上的slot的长度更长。因此，令WUR链路与NR系统系统的信号边界对齐时，可以令WUR帧中的第一时间单元的长度为NR系统的slot长度的整数倍，以此降低WUR链路的信号和NR系统的信号之间的干扰。
可选的，本申请实施例中，多个终端和/或小区可能共享同步信号发送位置，很可能造成干扰。为了避免不同终端和/或小区之间的干扰，所述方法还可以包括：终端接收网络设备发送的第二配置信息，比如终端可以通过主链路接收来自网络设备的第二配置信息，其中第二配置信息配置预留资源，预留资源上不能发送同步信号，以使得终端根据第二配置信息不在预留资源上发送同步信号。
本申请实施例中，预留资源可以包括在同步信号的候选发送位置中，预留资源为同步信号的候选发送位置中的部分候选发送位置，比如预留资源可以是候选发送位置中多个小区共享的候选发送位置，这意味着同步信号的候选发送位置中的部分位置被配置为不可用于该终端发送同步信号。具体的，同步信号的候选发送位置根据同步信号的发送周期确定，比如同步信号的候选发送位置可以是同步信号的发送周期所对应的位置，相邻候选发送位置之间的长度为一个发送周期。
例如，如图10g所示，假设相邻小区(小区1和小区2)都部署了WUR链路，若两个小区的WUR链路的时域资源是重叠的，比如同步信号发送位置是重叠，则这两个小区的WUR信号(比如同步信号)可能会存在相互干扰。为了避免干扰，相邻小区的WUR信号需要通过TDM的方式发送，即相邻小区的WUR信号最好在不同的时间位置发送。如图10g所示，将小区1和小区2中的部分同步信号发送位置作为预留资源，不在上面传输同步信号，使得能够发送同步信号的位置不重叠，以此避免小区间干扰。
