为了便于理解本申请实施例，下面对本申请实施例所涉及到的基本流程以及基本概念进行简单说明。应理解，下文所介绍的基本流程以及基本概念并不对本申请实施例产生限定。
5G的主要应用场景为：增强移动超宽带(eMBB，Enhanced Mobile Broadband)、低时延高可靠通信(URLLC，Ultra Reliable Low Latency Communications)、大规模机器类通信(mMTC，massive Machine Type Communications)。其中，eMBB以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速；由于eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度、小数据量、时延不敏感业务、低成本和长使用寿命等。
在5G网络环境中，为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义了新的RRC(无线资源控制，Radio Resource Control)状态，即RRC_INACTIVE(RRC非激活)状态。这种状态有别于RRC_IDLE(RRC空闲态)、RRC_ACTIVE(RRC激活态)或RRC_CONNECTED(RRC连接态)。
关于终端设备(或称为UE)的节能，分别进行说明：
第一、针对RRC连接态的终端设备的节能：
在5G的演进中，对UE(即终端设备)的节电提出了更高的要求。例如对于现有的DRX(Discontinuous Reception，非连续接收)机制，在每个on duration(激活时间)，UE(即终端设备)需要不断检测PDCCH(物理下行控制信道，Physical Downlink Control CHannel)来判断基站是否调度发给自己的数据传输。对于大部分UE(即终端设备)来说，可能在很长一段时间没有接收数据传输的需要，仍然需要保持定期的唤醒机制来监听可能的下行传输，对于这类UE(即终端设备)，节电有进一步优化的空间。
在R16标准中，引入了节能信号，以实现进一步的节能。该节能信号可以与DRX机制结合使用，该引入节能信号的处理方式，具体可以包括：终端设备在DRX ON duration(激活时间)之前，接收节能信号(或称为节能唤醒信号)。也就是，当针对一个终端设备在一个DRX周期有数据传输时，网络设备可以通过节能信号“唤醒”终端设备，以使得所述终端设备在唤醒后，在DRX On duration期间监 听PDCCH；否则，当针对一个终端设备在一个DRX周期没有数据传输时，不向该终端设备发送节能信号(也就是不“唤醒”终端设备)，以使得该终端设备在DRX On Duration期间不需要监听PDCCH。相比现有DRX机制，上述引入节能信号的处理方式，能够在终端设备没有数据传输时，省略DRX On duration期间PDCCH监听，从而实现终端设备的节能。其中，所述节能信号，可以由DCI(下行链路控制信息，DownLink Control Information)format(格式)2_6承载。
将终端设备在DRX(Discontinuous Reception，非连续接收)On duration之外的时间被称为非激活时间，在DRX On Duration的时间被称为激活时间，结合图2，对以上在DRX中引入节能信号的处理方式进行说明，可以包括：第一个节能信号指示监听PDCCH，则终端设备在接收到该第一个节能信号后，在第一个DRX周期的激活时间(第一个DRX周期的激活时间在图2中表示为黑色方框)内监听PDCCH；第二个节能信号指示不监听PDCCH，则终端设备在接收到该第二个节能信号后，不在第二个DRX周期的激活时间(第二个DRX周期的激活时间在图2中表示为无颜色方框)内监听PDCCH；第三个节能信号指示不监听PDCCH，则终端设备在接收到该第三个节能信号后，不在第三个DRX周期的激活时间(第三个DRX周期的激活时间在图2中表示为无颜色方框)内监听PDCCH；第四个节能信号指示监听PDCCH，则终端设备在接收到该第四个节能信号后，在第四个DRX周期的激活时间(第四个DRX周期的激活时间在图2中表示为黑色方框)内监听PDCCH。
在R17标准中，为了进一步增强连接态(即RRC连接态)的UE(即终端设备)的节能，引入了R16的搜索空间集合组切换的增强方案，以及在数据传输的间隙跳过PDCCH监听的方案(即PDCCH skipping(跳过)的方案)来实现节电。其中，搜索空间集合组切换和PDCCH skipping相关的控制信息可以是通过PDCCH承载的。
第二、针对RRC-Idle(RRC空闲态)/RRC-inactive(RRC非激活态)态终端设备的节能：
在RRC idle/inactive状态下的终端设备，通过DRX的方式接收寻呼消息。由于在一个DRX周期内存在一个寻呼时机(paging occasion，PO)，因此终端设备只在PO接收寻呼消息，而在PO之外的时间不接受寻呼消息，来达到省电的目的。但是实际情况下，终端设备被寻呼到的概率可能并不高，因此，若终端设备周期性的在对应的PO上检测PDCCH，而有很大概率并没有检测到发给自己的寻呼消息，则客观上会造成功率的浪费。
与R16标准针对RRC连接态的终端设备的节能类似，R17标准对空闲态的终端设备接收寻呼消息的节能进行了优化，引入了与前述节能信号类似的一种节能信号，称为PEI(paging early indication，寻呼早期指示)。该PEI用于在目标PO到达之前，指示终端设备是否在该PO接收寻呼PDCCH。上述节能信号(即PEI)承载于PDCCH信道(以下为了方便描述，将其称为基于PDCCH信道的节能信号)，具体通过DCI(下行链路控制信息，DownLink Control Information)format(格式)2_7携带该节能信号(即PEI)。
该基于PDCCH信道的节能信号可以承载更多的节能信息，例如，可以承载sub-grouping(子分组)信息，用于指示节能信息对应的终端设备子分组(或UE子分组)。可通过UE_ID(标识)将对应同一个PO的多个终端设备的进一步分组，得到多个终端设备组。若终端设备所在的终端设备组有任何一个终端设备需要被寻呼，则终端设备需要在该PO上接收寻呼消息，否则，终端设备不需要接收寻呼消息。以上通过将终端设备组(或称为终端设备子分组)信息与节能信息结合，可以更加精细的指示在目标PO是否需要接收寻呼的终端设备。比如，通过节能信号唤醒终端设备接收寻呼消息的一种场景，如图3所示：第一个节能信号指示一个或多个终端设备组中的终端设备在对应的PF(寻呼帧，Paging Frame)或者PO(在图3中将第一个节能信号所指示的PF或PO表示为灰色方块)上接收寻呼，则该终端设备组内的终端设备唤醒后，在PF或PO上监听寻呼；第二个节能信号则指示不监听PDCCH，也就是指示一个或多个终端设备组中的终端设备在对应的PF或者PO(在图3中将第二个节能信号所指示的PF或PO表示为无颜色方块)上不接收寻呼，则该终端设备组内的终端设备可以不在PF或PO上监听寻呼；第三个节能信号指示一个或多个终端设备组中的终端设备在对应的PF或者PO(在图3中将第三个节能信号所指示的PF或PO表示为灰色方块)上接收寻呼，则该终端设备组内的终端设备唤醒后，在PF或PO上监听寻呼。
为了终端设备的进一步节电，R18标准计划引入唤醒接收机(WUR,wake-up receiver)接收节能信号的方案。WUR具有极低成本、极低复杂度和极低功耗的特点，其主要通过基于包络检测的方式接收节能信号。因此，WUR接收的节能信号与现有R16、R17标准定义的基于PDCCH承载的信号的调制方式、波形等不同。节能信号主要通过对载波信号进行ASK调制的包络信号。包络信号的解调也可基于无线射频信号提供的能量驱动低功耗电路来完成，因此它可以是无源的。WUR也可以通过终端设备进行供电，无论哪种供电方式，该WUR相比终端设备的传统接收机都极大的降低了功耗，例如WUR可以实现小于1mw(毫瓦)的功耗，远低于传统接收机几十至几百mw的功耗。WUR可以和终端设备 结合在一起，作为终端设备接收机的一个附加模块，也可以单独作为一个终端设备的唤醒功能模块。

为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
图4是根据本申请一实施例的信息传输方法的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S410、终端设备监听唤醒信号(WUS，wake-up Signal)；其中，所述WUS包含N个信号部分；N为大于等于1的整数。
上述S410所述终端设备监听WUS，具体可以为：所述终端设备的第一部件监听所述WUS。其中，所述终端设备至少包含所述第一部件和第二部件；所述第一部件的功耗低于所述第二部件。
所述终端设备的第一部件监听所述WUS，可以指的是：所述终端设备处于RRC空闲态、或RRC非激活态的情况下，所述终端设备的第一部件监听所述WUS。还需要指出的是，在所述终端设备的第一部件监听所述WUS的过程中，所述终端设备的所述第二部件可以处于休眠状态。该休眠状态可以指的是所述第二部件一部分功能或一部分器件处于开启状态，但是另一部分功能或另一部分器件处于关闭状态或称为待唤醒状态等等。所述终端设备可以仅包含上述第一部件和第二部件；或者，所述终端设备除了包含上述第一部件和第二部件之外，还可以包含其他部件，只是本实施例不做穷举。
所述终端设备可以仅包含上述第一部件和第二部件；或者，所述终端设备除了包含上述第一部件和第二部件之外，还可以包含其他部件，只是本实施例不做穷举。
具体的，所述第一部件可以指的是所述终端设备中的低功耗接收机，或者可以称为唤醒接收机(WUR，wake-up receiver)，或者可以将其称为零功耗WUR，或者还可以称为低功耗WUR，关于其更多的名称本实施例不做穷举。所述第二部件可以指的是所述终端设备中的主接收机。
示例性的，如图5所示，所述终端设备可以由主接收机以及WUR构成。进一步的，如果网络设备需要终端设备开启第二部件即图5中的主接收机，则所述网络设备可以向所述终端设备发送WUS。相应的，所述终端设备的WUR可以监听唤醒信号(WUS，wake-up signal)；在终端设备的WUR监听到所述WUS的情况下，控制开启所述终端设备的主接收机(即前述第二部件)；在终端设备的WUR没有监听到所述WUS的情况下，终端设备的主接收机可以保持处于休眠状态。也就是说，在终端设备没有业务或没有寻呼消息时，终端设备可以仅使用WUR(即第一部件)；仅当终端设备有业务时，终端设备的WUR才会收到WUS，再唤醒终端设备的主接收机以进行数据收发。
为了便于区分，下文从调制方式、调制波形、传输速率、支持的带宽范围、码率等方面，介绍WUR与主接收机之间的差异：
从二者支持的调制方式来看，WUR支持的调制方式的复杂程度低于主接收机支持的调制方式的复杂程度。在一些实现方式中，WUR支持的调制方式可以包括以下调制方式中的一种或多种：幅移键控(amplitude shift keying，ASK)、相移键控(phase shift keying，PSK)、频移键控(frequency shift keying，FSK)等。相应地，主接收机支持的调制方式可以包括以下调制方式中的一种或多种：正交相移键控(quadrature phase shift keying，QPSK)、正交振幅调制(quadrature amplitude modulation，QAM)、正交频分复用(orthogonal frequency division multiplexing，OFDM)等。当然，在另一些实现方式中，主接收机也可以支持ASK、PSK、FSK中的至少之一的调制方式。本申请实施例对此不作具体限定。
从二者支持的调制波形来看，WUR支持的调制波形的复杂度低于主接收机支持的调制波形的复杂度，或者说，WUR支持的调制波形比主接收机支持的调制波形简单。
从二者支持的传输速率来看，WUR支持的传输速率低于主接收机支持的传输速率。
从二者支持的带宽范围来看，WUR支持的带宽范围小于主接收机支持的带宽范围，或者说，WUR支持的带宽比主接收机支持的带宽窄。
从二者支持的码率来看，WUR支持的码率低于主接收机支持的码率。
本实施例提供的方案中，所述终端设备的第一部件(即WUR)监听所述WUS，可以节省终端设备的功耗。这是由于终端设备的WUR工作时使用极低的功耗(一般小于1mw)；并且，终端设备的 WUR使用ASK或FSK的方式对信号进行调制，这也使得终端设备的WUR可以采用极其简单的硬件结构和极其简单的接收方式对信号进行接收和解调，例如，针对ASK信号，终端设备的WUR仅需要使用包络检测的方式对信号进行接收。因此，相对传统的终端设备一直使用主接收机的模式，本实施例采用终端设备的WUR监听WUS，能够极大节省终端设备的功耗。
下面首先针对所述WUS包含的N个信号部分进行说明：
所述N个信号部分中包含第一信号部分，所述第一信号部分用于携带目标信息。所述目标信息包括以下至少之一：唤醒信息，寻呼短消息。
上述目标信息为所述WUS承载的主要信息。
所述目标信息中可以仅包含所述唤醒信息；或者，所述目标信息中可以仅包含所述寻呼短消息；或者，所述目标信息中可以既包含所述唤醒信息又包含所述寻呼短消息。
其中，所述寻呼短消息可以包含以下至少之一：Earthquake and Tsunami Warning System(地震和海啸预警系统，ETWS)通知，Commercial Mobile Alert System(商用移动预警系统，CMAS)通知，系统消息是否更新的指示信息。应理解，以上仅为示例性说明，根据实际的情况或需求，所述寻呼短消息还可以包含其他类型的通知和/或指示信息，只是本实施例不进行穷举。
所述唤醒信息，还可以称为节能指示信息。该唤醒信息可以用于指示所述终端设备监听寻呼消息；具体的，该唤醒信息可以是用于指示所述终端设备是否需要接收寻呼消息，也就是该唤醒信息用于指示所述终端设备在所述终端设备的PO(寻呼时机)上是否有寻呼消息发送。比如，在网络设备需要唤醒终端设备以在其PO上监听寻呼消息的时候，该网络设备可以向所述终端设备发送WUS，该WUS的第一信号部分中携带所述唤醒信息。其中，所述终端设备可以是处于RRC空闲态或RRC非激活态。
进一步地，所述唤醒信息为所述终端设备专属的；或者所述唤醒信息为终端设备组共享的，所述终端设备组中包含所述终端设备；或者所述唤醒信息为第一服务小区专用的，所述第一服务小区为所述终端设备所在的服务小区。
分别来说：
在第一种情况中，所述唤醒信息可以为所述终端设备专属的。
也就是网络设备为唤醒该终端设备，而向该终端设备发送的WUS，所述WUS的所述第一信号部分中携带所述终端设备专属的所述唤醒信息。
应理解，这种情况下，所述唤醒信息中可以包括：所述终端设备的标识。其中，所述终端设备的标识可以为以下任意之一：可以采用临时移动用户识别码(TMSI，Temporary Mobile Subscriber Identity)、国际移动用户识别码(IMSI，International Mobile Subscriber Identity)、I-RNTI(Inactive Radio Network Temporary Identifier，非激活无线网络临时标识)。
终端设备在接收到该WUS后，从该WUS的第一信号部分中获取到所述唤醒信息，若该唤醒信息中包含所述终端设备的标识，则终端设备可以基于所述唤醒信息包含的具体内容，执行后续处理。比如该唤醒信息用于指示所述终端设备监听寻呼消息，则所述终端设备可以唤醒第二部件(即主接收机)监听所述寻呼消息。
在第二种情况中，所述唤醒信息为终端设备组共享的，所述终端设备组中包含所述终端设备。
所述终端设备组的数量可以为一个或多个，本实施例不对其进行限定。即所述唤醒信息可以为一个或多个终端设备组共享的。并且，本实施例中所述终端设备为前述一个或多个终端设备组的全部终端设备中的任意之一。
也就是网络设备为唤醒一个或多个终端设备组，而向该一个或多个终端设备组的全部终端设备发送的WUS，所述WUS的所述第一信号部分中携带所述一个或多个终端设备组共享的所述唤醒信息。
应理解，这种情况下，所述唤醒信息中还可以包括以下之一：所述终端设备组的标识、比特图(bitmap)。
具体来说，所述终端设备组的标识可以为一个或多个终端设备组的标识。相应的，终端设备在接收到该WUS后，从该WUS的第一信号部分中获取到所述唤醒信息，若该唤醒信息中包含所述终端设备所在的终端设备组的标识，则所述终端设备唤醒并基于所述唤醒信息包含的具体内容，执行后续处理。比如该唤醒信息用于指示所述终端设备组内的终端设备监听寻呼消息，则所述终端设备可以唤醒第二部件(即主接收机)监听所述寻呼消息。
所述比特图(bitmap)中可以包含Q个比特位，Q为大于等于1的整数。在所述比特图中包含的所述Q个比特位中，每个比特位可以用于对应一个终端设备组，且不同比特位对应不同的终端设备组。
所述Q个比特位中，每一个比特位的取值可以用于指示是否唤醒对应的终端设备组中的终端设备。
其中，每一个比特位的取值可以包括二进制第一值和二进制第二值。二进制第一值用于指示唤醒对应的终端设备组中的终端设备，也就是该二进制第一值用于指示对应的终端设备组中的终端设备唤醒第 二部件；二进制第二值用于指示不唤醒对应的终端设备组中的终端设备，也就是二进制第二值用于指示终端设备组中的所述终端设备不唤醒第二部件。该二进制第一值和二进制第二值不同，比如二进制第一值为1、二进制第二值为0，或者二进制第一值为0、二进制第二值为1。
比如，终端设备在接收到该WUS后，从该WUS的第一信号部分中获取到所述唤醒信息，若该唤醒信息中包含比特图，则从所述比特图中获取所述终端设备所在的终端设备组所对应的比特位的取值；若该比特位的取值为二进制第一值，则所述终端设备可以唤醒第二部件(即主接收机)监听寻呼消息。
在第三种情况中，所述唤醒信息为第一服务小区专用的，所述第一服务小区为所述终端设备所在的服务小区。
也就是网络设备为唤醒第一服务小区内的全部终端设备，向该第一服务小区内的全部终端设备发送的WUS，所述WUS的所述第一信号部分中携带所述第一服务小区内的全部终端设备共享的所述唤醒信息。相应的，上述第一服务小区内的全部终端设备都可以监听到所述WUS。本实施例中所述终端设备为所述第一服务小区内的全部终端设备中的任意之一。
应理解，这种情况下，所述唤醒信息中还可以包括：所述第一服务小区的标识。也就是说，终端设备在接收到该WUS后，从该WUS的第一信号部分中获取到所述唤醒信息，若该唤醒信息中携带所述第一服务小区的标识、且所述第一服务小区为终端设备所在小区，则所述终端设备唤醒第二部件(即主接收机)监听所述寻呼消息。
或者，这种情况下，所述唤醒信息中还可以不携带标识或比特图。也就是说，终端设备在接收到该WUS后，从该WUS的第一信号部分中获取到所述唤醒信息，若该唤醒信息中不携带标识或比特图，则所述终端设备直接唤醒第二部件(即主接收机)监听所述寻呼消息。
示例性的，前述第一信号部分中携带的所述目标信息，如图6所示，可以表示为数据(Data)。
在所述第一信号部分用于携带所述目标信息的基础上，本实施例提供的方案中，所述第一信号部分，还可以用于携带同步序列，所述同步序列用于所述终端设备维持同步。
所述同步序列，位于以下位置之一：
所述第一信号部分之前；
所述第一信号部分之内；
所述第一信号部分之后。
需要指出的是，在所述第一信号部分中可以携带同步序列，还可以不携带同步序列。并且，在所述第一信号部分中携带所述同步序列的情况下，所述同步序列的数量可以为一个或多个。
关于所述第一信号部分中是否携带所述同步序列，或者所述第一信号部分中携带所述同步序列的数量，可以根据实际情况确定。具体来说，所述第一信号部分中是否携带所述同步序列，或者所述第一信号部分中携带所述同步序列的数量，可以与所述目标信息的长度相关。
举例来说，在目标信息的长度小于第一预设数量的情况下，所述第一信号部分中可以不携带同步序列；所述第一预设数量可以根据实际情况设置，比如可以是8byte或2byte，或更短或更长，不做穷举。
在目标信息的长度大于等于所述第一预设数量的情况下，所述第一信号部分中可以携带同步序列。此时，所述同步序列的数量同样可以与所述目标信息的长度相关，比如，可以预设第一对应关系，该预设第一对应关系中可以包括预设长度及其对应的预设数量；相应的，可以基于所述目标信息的长度，从所述预设第一对应关系中确定目标长度，将该目标长度对应的目标数量，作为所述同步序列的数量。
在所述同步序列的数量为一个的情况下，该一个同步序列可以位于所述第一信号部分之前、或位于所述第一信号部分之内、或位于所述第一信号部分之后。
这种情况下，该一个同步序列的长度可以根据实际情况配置，比如，可以固定为8个比特的长度，或者可以更长或更短，这里不做穷举。该一个同步序列的具体内容可以根据实际情况设置，只要通信双方预先协商好即可，这里不对其进行限定。
在所述同步序列的数量为多个的情况下，该多个同步信号中不同的同步信号的位置可以不同；该多个同步信号中，任意一个同步序列可以是在所述第一信号部分之前、或位于所述第一信号部分之内、或位于所述第一信号部分之后。
这种情况下，多个同步信号中不同的同步序列的长度可以为相同的，每个同步信号的长度根据实际情况配置，比如，可以固定为8个比特的长度，或者可以更长或更短，这里不做穷举。多个同步信号中不同的同步序列的具体内容可以是相同的，具体可以根据实际情况设置，只要通信双方预先协商好即可，这里不对其进行限定。
示例性的，所述同步序列的数量可以为2个，这2个同步序列可以如图7所示表示为“SYNC 1”和“SYNC 2”，这两个同步序列“SYNC 1”和“SYNC 2”，均位于所述第一信号部分之内。这里需要指出的是，由于第一信号部分携带所述图7中的数据(data)即目标信息，因此，虽然图7中将两个同 步序列“SYNC 1”和“SYNC 2”添加在数据(data)中，但不代表是在目标信息中添加了“SYNC 1”和“SYNC 2”，可以理解为在第一信号部分之内的两个任意时域位置处添加了“SYNC 1”和“SYNC 2”。
所述第一信号部分，还用于携带逆向比特，所述逆向比特用于确定包络检测门限。其中，逆向比特可以表示为“inverse bit”。
所述逆向比特，位于所述目标信息的部分比特位中。
所述逆向比特，可以是在所述目标信息中每隔指定数量个比特位的位置处添加的。所述指定数量可以根据实际情况设置，比如可以是10、20、或更多或更少，这里不做穷举。
或者，所述逆向比特，可以是在所述目标信息中，存在超过预设比特数量门限值个取值相同的连续比特位的情况下，在该连续比特位中任意位置处添加的。其中，所述预设比特数量门限值可以根据实际情况设置，比如10个、16个、20个，或更多或更少，这里不对其进行穷举。
所述逆向比特的数量可以为一个或多个，这里不对其进行限定。
再进一步地，所述逆向比特的取值与所述目标信息的部分比特位的取值不同。
比如，可以在所述目标信息中每隔指定数量个比特位的位置处，添加与该位置相邻的比特位的取值相反取值的逆向比特。
比如，所述逆向比特在连续的多个取值为1的比特位中的时候，该逆向比特为0；反之，所述逆向比特在连续的多个取值为0的比特位中的时候，该逆向比特为1。假设所述预设比特数量门限值可以为10，也就是说，所述目标信息中有连续传输11个或更多取值为1的部分比特位的时候，可以在这部分比特位中任意的位置处添加逆向比特0。比如，可以在部分比特位中连续添加2个逆向比特0，或者添加1个逆向比特0，这里不对其数量进行限定。
以上为针对所述WUS的第一信号部分的详细说明。在一种可能的实施方式中，所述WUS的所述N个信号部分，除了上述所述第一信号部分之外，还可以包括其他信号部分，下面进一步进行说明：
所述N个信号部分，还包含以下至少之一：
第二信号部分，所述第二信号部分用于携带第一信号序列，所述第一信号序列用于指示WUS的起始位置；
第三信号部分，所述第三信号部分用于携带前导序列，所述前导序列用于进行时钟同步；
第四信号部分，所述第四信号部分用于携带循环冗余校验码(CRC，Cyclic Redundancy Check)；
第五信号部分，所述第五信号部分用于携带第二信号序列，所述第二信号序列用于指示WUS的结束位置。
分别来说，所述第二信号部分用于携带第一信号序列；其中，所述第一信号序列可以如图6和图7所示，具体为“SOW”即Start Of WUS(唤醒信号的起始)。
所述第一信号序列的长度可以根据实际情况设置，比如，所述第一信号序列的长度可以为固定值，比如4bit，或更长或更短，这里不对其进行限定。
所述第一信号序列的具体内容，可以根据实际情况设置，只要通信双方预先确认具备相同含义即可。比如，所述第一信号序列具体可以为一种特殊的或指定的信号序列，如1111，或1010等。由于WUS一般使用OOK调制，因此可以使用特殊的信号序列作为所述第一信号序列，用于表示WUS开始传输，也即表示在SOW(即第一信号序列)之后，为WUS的具体内容开始发送位置。相应的，在所述终端设备(具体为终端设备的第一部件)接收并识别到该第一信号序列的情况下，确定收到SOW，进而开始接收WUS的具体内容。这里，所述WUS的具体内容可以指的是前述目标信息，另外还可以包含前导序列、CRC等等。
所述第三信号部分用于携带前导序列。该前导序列如图6或图7所示可以表示为前导序列(preamble)。
所述前导序列的主要功能是用于进行时钟同步。
所述终端设备(具体为终端设备的第一部件)在接收到该前导序列的情况下，可以通过获取前导序列(preamble)中多个调制符号之间的时间间隔，获得时钟信息(如系统的时钟频率，或如两个调制符号之间的间隔)，从而基于该时钟信息可以接收后续的data(即第一信号部分中携带的目标信息)。
此外，所述前导序列还可以用于指示所述WUS的信号参数；所述WUS的信号参数包括以下至少之一：信号长度、传输速率。
所述前导序列可以仅指示所述信号长度；或者所述前导序列可以仅指示所述传输速率；或者，所述前导序列可以既指示所述信号长度，又指示所述传输速率。
所述信号长度可以指的是所述WUS携带的全部内容的长度，比如240bit(或更长或更短)。
或者，所述信号长度可以可以指的是所述WUS携带的N个信号部分分别对应的长度。
或者，所述信号长度可以指的是：全部N个信号部分中，某一个或多个信号部分的长度。比如， 该信号长度仅用于指示第一信号部分的长度为A bit；又比如，该信号长度用于指示第一信号部分的长度为A bit，第二信号部分的长度为B bit等等。
所述传输速率具体可以指的是WUS的传输速率。该传输速率的单位可以为每秒比特率kbps。所述传输速率的具体数值，本实施例不做限定。
所述第四信号部分用于携带循环冗余校验码CRC；比如图6或图7中示意出的CRC。该CRC用于对第一信号部分(即Data)携带的信息进行CRC校验，以检验WUR接收的data部分是否正确。
所述第五信号部分用于携带的第二信号序列；该第二信号序列与前述第一信号序列对应。示例性的，所述第二信号序列，可以如图6或图7所示，表示为EOW(End Of WUS，唤醒信号的结束)，即EOW用于表征WUS的结束位置。
所述第二信号序列的长度可以根据实际情况设置。比如，所述第二信号序列的长度可以为固定值，比如4bit，或更长或更短，这里不对其进行限定。
所述第二信号序列的具体内容可以根据实际情况设置。所述第二信号序列可以是另一种特殊的或指定的信号序列，如“1110”，或“110”等。
应理解，前述实施例中已经说明，所述第一信号序列也为一种特殊的或指定的信号序列。这里，所述第二信号序列与所述第一信号序列可以为不同的特殊的或指定的信号序列，或者，所述第二信号序列与所述第一信号序列可以为相同的特殊的或指定的信号序列。
以上为针对所述WUS中N个信号部分所分别携带的具体信息的详细说明。这里需要进一步说明的是，实际处理中所述WUS除了包含所述第一信号部分之外，可以不包含其他信号部分；或者所述WUS除了包含所述第一信号部分之外，可以包含其他信号部分中的一部分；或者，所述WUS可以包含上述N个信号部分的全部。均在本实施例的保护范围内。
在一种可能的实施方式中，所述N个信号部分中不同信号部分采用相同的符号长度。或者，所述N个信号部分中至少一个信号部分与其他信号部分采用不同的符号长度。
也就是上述WUS的各个信号部分，使用的符号长度可以是相同的，也可以是不同的。其中，所述符号可以指的是OFDM符号。
关于所述N个信号部分中至少一个信号部分与其他信号部分采用不同的符号长度，可以是上述N个信号部分中M个信号部分采用的符号长度相同均为第一符号长度，剩余N-M个信号部分的符号长度相同均为第二符号长度，其中，第一符号长度与第二符号长度不同。M为小于N的整数。
又或者，所述N个信号部分中至少一个信号部分与其他信号部分采用不同的符号长度，可以是所述N个信号部分中不同信号部分采用不同的符号长度。也就是，任意一个信号部分采用的符号长度与其他信号部分均不相同。
其中，所述不同的符号长度之间的关系可以是指的不同的符号长度之间的比例关系，或倍数关系。比如，第三信号部分中携带的前导序列(preamble)的符号长度是第一信号部分中携带的目标信息的符号长度的1/2。
所述不同的符号长度之间的关系，可以为预设的，或网络设备配置的。所述不同的符号长度之间的关系为网络设备配置的，具体可以是由网络通知终端设备的，比如通过RRC信令、DCI或系统广播消息通知所述终端设备的。以上实施方式中，所述WUS不同的信号部分使用不同的符号长度，能够更加有利于控制不同的信号部分的开销。例如，在preamble的长度(即信息比特数量)一定的情况下，相对使用长的preamble符号长度而言，使用较短的preamble符号长度可以使得preamble所占用的总时间长度较短。
上述实施例中说明了WUS所能够携带的具体信息内容及其格式。进一步地，在终端设备接收到(或监听到)WUS的时候，可以依次解析得到每一个比特位的取值，将全部比特位的取值依次组合，可以得到所述WUS的全部内容。其中，所述依次组合可以指的是根据接收时间的前后顺序进行组合。
在一种实施方式中，该WUS在传输的时候可以占用一部分主系统(主接收机对应的系统)的频谱，或者占用一段专用的频谱资源。上述WUS的传输方式可以有以下三种，分别来说：
第一种方式、
上述WUS为二进制启闭键控(OOK，On-Off Keying)信号。所述OOK信号基于移幅键控法(ASK，Amplitude-Shift Keying)或移频键控法(FSK，Frequency-Shift Keying)调制得到。
这种方式中，所述WUS中的第k个比特位的取值，由所述OOK信号的第k个幅度确定的，k为大于等于1的整数。其中，所述OOK信号的第k个幅度具体可以指的是，所述OOK信号在第k个时刻的幅度。
具体的，所述终端设备(具体为所述终端设备的第一部件)接收到所述OOK信号的第k个时刻的幅度为第一幅度，则可以确定WUS中的第k个比特位的取值可以为第一值；所述终端设备(具体为所 述终端设备的第一部件)接收到所述OOK信号的第k个时刻的幅度为第二幅度，则可以确定WUS中的第k个比特位的取值为第二值。
其中，所述第一幅度与第二幅度不同，比如，所述第一幅度可以大于或等于第一幅度阈值，第二幅度可以小于所述第一幅度阈值，或者反之亦然。所述第一幅度阈值可以根据实际情况设置，可以与网络设备侧实际传输OOK信号的功率大小、路损等等相关，本实施例不对其进行限制。
所述第一值与所述第二值不同，比如，所述第一值为1，所述第二值为0；或者，所述第一值为0，所述第二值为1。
举例来说，所述终端设备(具体为所述终端设备的第一部件)接收到所述OOK信号的第k个时刻的幅度小于第一幅度阈值，则可以确定WUS中的第k个比特位的取值可以为0；所述终端设备(具体为所述终端设备的第一部件)接收到所述OOK信号的第k个时刻的幅度大于或等于第一幅度阈值，则可以确定WUS中的第k个比特位的取值为1；或者反之亦然。这里仅为示例性说明，不作为对本实施例的限定。
所述WUS可能占用一段专用的频域资源(或专用的频域资源)；或者所述WUS可能占用一部分主系统(主接收机对应的系统)的频域资源。
第二种方式、
所述WUS为基于OFDM(正交频分复用，Orthogonal Frequency Division Multiplexing)符号上的多个目标子载波生成的OOK信号。
上述WUS为基于OFDM符号上的多个目标子载波生成的OOK信号，具体可以指的是：所述WUS为通过生成OFDM波形的方式模拟生成的OOK信号。
进一步地，所述WUS中的第i个比特位的取值，由第i个时域位置处第一频域范围内接收到的信号状态确定，i为大于等于1的整数；其中，所述第i个时域位置为第i个OFDM符号所在位置；所述第一频域范围与所述多个目标子载波所占用的频域范围相关。其中，所述第i个OFDM符号为前述用于生成OOK信号的OFDM符号中任意之一。
具体来说：所述终端设备在第i个时域位置处第一频域范围内接收到的信号状态为第一信号状态的情况下，确定所述第i个比特位的取值为第一值；所述终端设备在第i个时域位置处第一频域范围内接收到的信号状态为第二信号状态的情况下，确定所述第i个比特位的取值为第二值。
其中，所述信号状态具体可以指的是信号的能量值或信号的幅度值。所述信号状态可以包括第一信号状态或第二信号状态。所述第一信号状态与第二信号状态不同，比如，所述第一信号状态可以指的是信号的能量值大于第一能量阈值的状态，第二信号状态可以指的是信号的能力值小于或等于所述第一能量阈值的状态，或者反之。又比如，所述第一信号状态可以指的是信号的幅度值大于第二幅度阈值的状态，第二信号状态可以指的是信号的幅度值小于或等于所述第二幅度阈值的状态，或者反之。
所述第i个比特位的取值可以为第一值或第二值。所述第一值与所述第二值不同，比如，所述第一值为1，所述第二值为0；或者，所述第一值为0，所述第二值为1。
所述第一频域范围与所述多个目标子载波所占用的频域范围相关，具体可以指的是：所述第一频域范围与多个目标子载波所占用的频域范围相同；或者，所述第一频域范围在多个目标子载波所占用的频域范围之内、且所述第一频域范围小于所述多个目标子载波所占用的频域范围。
再进一步来说，前述第一频域范围的大小可以为预设的，比如在所述终端设备上一次处于RRC连接态的情况下，通过接收DCI、RRC信令、系统消息中任意之一获取到的。
又或者，前述第一频域范围可以是基于多个目标子载波的相关信息确定的；这种情况下，尤其需要预先获取到所述多个目标子载波的相关信息，比如，所述多个目标子载波的相关信息，可以包括以下至少之一：所述多个目标子载波的子载波间隔、所述OFDM符号的相关配置、CP的长度、多个目标子载波的数量。相应的，这种情况下，所述终端设备可以基于所述多个目标子载波的相关信息，确定多个目标子载波所占用的频域范围，基于所述多个目标子载波所占用的频域范围，确定所述第一频域范围。
其中，所述多个目标子载波，可以为OFDM符号中的部分子载波或者全部子载波。
在所述多个目标子载波为OFDM符号中的部分子载波的情况下，所述多个目标子载波中，不包含中心子载波。也就是说，任意一个OFDM符号上除了中心子载波之外的其他子载波中的至少部分作为上述多个目标子载波。比如，可以是除了中心子载波之外的其他全部子载波均作为所述多个目标子载波；或者，可以是可以是除了中心子载波之外，其他全部子载波中选取至少两个作为所述多个目标子载波。
进一步地，在上述多个目标子载波为所述OFDM符号中的部分子载波的情况中，所述多个目标子载波以所述中心子载波为中心对称分布。比如，图8中示意出OFDM符号中OFDM上的多个目标子载波的数量为4，也就是WUS传输使用的4个目标子载波；进一步地，仍参见图8，WUS传输使用的4个目标子载波，以中心子载波(在图8中表示为黑色背景方形格样式)为中心对称分布。
所述多个目标子载波的数量，为网络设备配置的，或预先设置的。具体来说，在基于OFDM符号上的多个目标子载波传输WUS的方式中，所述目标子载波的数量越多，越有利于增强覆盖，也适合于支持大的小区半径。反之，较少的目标子载波的数量适合于支持较少的小区。应理解，在子载波间隔一定的情况下，多个目标子载波正比于WUS所占的带宽。因此，多个目标子载波的灵活配置也等价于WUS所占带宽的灵活配置。为了支持网络部署的灵活性，目标子载波的数量可以灵活配置，比如可以是预先设定，或者网络设备配置。其中，网络设备配置的方法可以是由网络设备通过系统消息、RRC信令或DCI中任意之一通知给终端设备。
所述OFDM符号不包含循环前缀CP。或者，所述OFDM符号包含循环前缀CP。也就是说，所述WUS为基于OFDM符号上的多个目标子载波生成的OOK信号，即使用OFDM方式生成WUS信号时，OFDM符号可以没有CP，或者，每一个OFDM符号上均有CP。
在所述OFDM符号包含循环前缀CP的情况下，所述CP的长度与主系统的载波至少部分不同。所述CP的长度为网络设备配置的，或预先设置的。
所述多个目标子载波的子载波间隔，与主系统相同。或者，所述多个目标子载波的子载波间隔，与主系统不同。所述多个目标子载波的子载波间隔为网络设备配置的，或预先设置的。
采用第二种方式，可以存在以下优点：OFDM可以使用FFT方式实现，因此能够与主系统共享FFT变换器，实现复杂度低；在OFDM的多个子载波上发送OOK信号，可以增大OOK信号的发射功率，保证终端设备的接收性能。
第三种方式，
所述WUS为基于单载波生成的OOK信号。
所述WUS中的第j个比特位的取值，由第j个时域位置处第二频域范围内接收到的信号状态确定，j为大于等于1的整数；其中，所述第二频域范围与所述单载波所占用的频域范围相关。
这种方式中，所述第二频域范围与所述单载波所占的频域范围相关。比如，所述第二频域范围可以为预设的，或者可以为网络设备配置的，或者可以基于所述单载波所占的频域范围确定的。
具体来说：所述终端设备在第j时域位置处第二频域范围内接收到的信号状态为第三信号状态的情况下，确定所述第j个比特位的取值为第一值；所述终端设备在第j个时域位置处第二频域范围内接收到的信号状态为第四信号状态的情况下，确定所述第j个比特位的取值为第二值。
其中，所述信号状态具体可以指的是信号的能量值或信号的幅度值。所述信号状态可以包括第三信号状态或第四信号状态。所述第三信号状态与第四信号状态不同，比如，所述第三信号状态可以指的是信号的能量值大于第二能量阈值的状态，第四信号状态可以指的是信号的能力值小于或等于所述第二能量阈值的状态，或者反之。又比如，所述第三信号状态可以指的是信号的幅度值大于第三幅度阈值的状态，第四信号状态可以指的是信号的幅度值小于或等于所述第三幅度阈值的状态，或者反之。
需要指出的是，这里所述第二能量阈值与前述第二种方式中的第一能量阈值可以相同或不同，所述第三幅度阈值与前述第二种方式中的第二幅度阈值可以相同或不同。
在一种示例中，所述第二能量阈值可以小于所述第一能量阈值，所述第三幅度阈值可以小于第二幅度阈值。这是由于，第二种方式中是通过多个子载波传输WUS，其信号的能量或幅度可能会大于本方式中单载波传输WUS，因此，可以将第二能量阈值或第三幅度阈值设置为小于第二种方式的第一能量阈值以及第二幅度阈值，以保证本方式可以更加准确的获取每一个比特位的取值。
所述比特位的取值可以为第一值或第二值。所述第一值与所述第二值不同，比如，所述第一值为1，所述第二值为0；或者，所述第一值为0，所述第二值为1。
其中，所述第二频域范围为网络设备配置的，可以指的是，在所述终端设备上一次处于RRC连接态的情况下，从网络设备发来的DCI、RRC信令、系统消息中任意之一中获取到的。
所述第二频域范围为基于所述单载波所占的频域范围确定的，可以指的是，所述终端设备预先获取到所述单载波所占的频域范围，确定所述第二频域范围等于所述单载波所占的频域范围；或者，所述终端设备预先获取到所述单载波所占的频域范围，确定所述第二频域范围为所述单载波所占的频域范围内的部分频域范围。
可见，通过采用上述方案，终端设备所监听的WUS中，可以携带N个信号部分，这样可以对WUS所能够携带的内容作出划分，从而在保证终端设备的节能的情况下，还能够在WUS中更加灵活的携带相应的信号部分，从而可以更加灵活的适用于更多的场景。另外，上述方案中还提供了针对WUS的符号长度以及多种传输方式的设计，从而保证了WUS的传输更加合理，适宜在低功耗的多种场景下进行部署。
图9是根据本申请一实施例的信息传输方法的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S910、网络设备发送唤醒信号WUS；其中，所述WUS包含N个信号部分；N为大于等于1的整数。
下面首先针对所述WUS包含的N个信号部分进行说明：
所述N个信号部分中包含第一信号部分，所述第一信号部分用于携带目标信息。所述目标信息包括以下至少之一：唤醒信息，寻呼短消息。
上述目标信息为所述WUS承载的主要信息。
所述目标信息中可以仅包含所述唤醒信息；或者，所述目标信息中可以仅包含所述寻呼短消息；或者，所述目标信息中可以既包含所述唤醒信息又包含所述寻呼短消息。
其中，所述寻呼短消息可以包含以下至少之一：Earthquake and Tsunami Warning System(地震和海啸预警系统，ETWS)通知，Commercial Mobile Alert System(商用移动预警系统，CMAS)通知，系统消息是否更新的指示信息。应理解，以上仅为示例性说明，根据实际的情况或需求，所述寻呼短消息还可以包含其他类型的通知和/或指示信息，只是本实施例不进行穷举。
所述唤醒信息，还可以称为节能指示信息。该唤醒信息可以用于指示所述终端设备监听寻呼消息；具体的，该唤醒信息可以是用于指示终端设备是否需要接收寻呼消息，也就是该唤醒信息用于指示终端设备在其PO(寻呼时机)上是否有寻呼消息发送。也就是在网络设备需要唤醒终端设备以在其PO上监听寻呼消息的时候，该网络设备可以向所述终端设备发送WUS，该WUS的第一信号部分中携带所述唤醒信息。其中，所述终端设备可以处于RRC空闲态或RRC非激活态。
进一步地，所述唤醒信息为终端设备专属的；或者所述唤醒信息为终端设备组共享的；或者所述唤醒信息为第一服务小区专用的。
分别来说：
在第一种情况中，所述唤醒信息可以为终端设备专属的。
也就是网络设备为唤醒某一个终端设备，而向该终端设备发送的WUS，所述WUS的所述第一信号部分中携带所述终端设备专属的所述唤醒信息。
应理解，这种情况下，所述唤醒信息中还可以包括：所述终端设备的标识。其中，所述终端设备的标识可以为以下任意之一：可以采用临时移动用户识别码(TMSI，Temporary Mobile Subscriber Identity)、国际移动用户识别码(IMSI，International Mobile Subscriber Identity)、I-RNTI(Inactive Radio Network Temporary Identifier，非激活无线网络临时标识)。
在第二种情况中，所述唤醒信息为终端设备组共享的。
所述终端设备组的数量可以为一个或多个，本实施例不对其进行限定。即所述唤醒信息可以为一个或多个终端设备组共享的。
也就是网络设备为唤醒一个或多个终端设备组，而向该一个或多个终端设备组的全部终端设备发送的WUS，所述WUS的所述第一信号部分中携带所述一个或多个终端设备组共享的所述唤醒信息。相应的，上述一个或多个终端设备组中的全部终端设备都可以监听到所述WUS。
应理解，这种情况下，所述唤醒信息中还可以包括以下之一：所述终端设备组的标识、比特图(bitmap)。
具体来说，所述终端设备组的标识可以为一个或多个终端设备组的标识。
所述比特图(bitmap)中可以包含Q个比特位，Q为大于等于1的整数。在所述比特图中包含的所述Q个比特位中，每个比特位可以用于对应一个终端设备组，且不同比特位对应不同的终端设备组。
所述Q个比特位中，每一个比特位的取值可以用于指示是否唤醒对应的终端设备组中的终端设备。
其中，每一个比特位的取值可以包括二进制第一值和二进制第二值。二进制第一值用于指示唤醒对应的终端设备组中的终端设备，也就是该二进制第一值用于指示对应的终端设备组中的终端设备唤醒第二部件；二进制第二值用于指示不唤醒对应的终端设备组中的终端设备，也就是二进制第二值用于指示终端设备组中的所述终端设备不唤醒第二部件。该二进制第一值和二进制第二值不同，比如二进制第一值为1、二进制第二值为0，或者二进制第一值为0、二进制第二值为1。
在第三种情况中，所述唤醒信息为第一服务小区专用的。
所述第一服务小区为所述网络设备的多个服务小区中的至少之一，也就是说，所述第一服务小区的数量可以为一个或多个。
也就是网络设备为唤醒第一服务小区内的全部终端设备，向该第一服务小区内的全部终端设备发送的WUS，所述WUS的所述第一信号部分中携带所述第一服务小区内的全部终端设备共享的所述唤醒信息。
应理解，这种情况下，所述唤醒信息中还可以包括：所述第一服务小区的标识。或者，这种情况下，所述唤醒信息中还可以不携带标识或比特图。
示例性的，前述第一信号部分中携带的所述目标信息，如图6所示，可以表示为数据(Data)。
在所述第一信号部分用于携带所述目标信息的基础上，本实施例提供的方案中，所述第一信号部分，还可以用于携带同步序列，所述同步序列用于所述终端设备维持同步。
所述同步序列，位于以下位置之一：
所述第一信号部分之前；
所述第一信号部分之内；
所述第一信号部分之后。
需要指出的是，在所述第一信号部分中可以携带同步序列，还可以不携带同步序列。并且，在所述第一信号部分中携带所述同步序列的情况下，所述同步序列的数量可以为一个或多个。
关于所述第一信号部分中是否携带所述同步序列，或者所述第一信号部分中携带所述同步序列的数量，可以根据实际情况确定。具体来说，所述第一信号部分中是否携带所述同步序列，或者所述第一信号部分中携带所述同步序列的数量，可以与所述目标信息的长度相关。
举例来说，在目标信息的长度小于第一预设数量的情况下，所述第一信号部分中可以不携带同步序列；所述第一预设数量可以根据实际情况设置，比如可以是8byte或2byte，或更短或更长，不做穷举。
在目标信息的长度大于等于所述第一预设数量的情况下，所述第一信号部分中可以携带同步序列。此时，所述同步序列的数量同样可以与所述目标信息的长度相关，比如，可以预设第一对应关系，该预设第一对应关系中可以包括预设长度及其对应的预设数量；相应的，可以基于所述目标信息的长度，从所述预设第一对应关系中确定目标长度，将该目标长度对应的目标数量，作为所述同步序列的数量。
在所述同步序列的数量为一个的情况下，该一个同步序列可以位于所述第一信号部分之前、或位于所述第一信号部分之内、或位于所述第一信号部分之后。
这种情况下，该一个同步序列的长度可以根据实际情况配置，比如，可以固定为8个比特的长度，或者可以更长或更短，这里不做穷举。该一个同步序列的具体内容可以根据实际情况设置，只要通信双方预先协商好即可，这里不对其进行限定。
在所述同步序列的数量为多个的情况下，该多个同步信号中不同的同步信号的位置可以不同；该多个同步信号中，任意一个同步序列可以是在所述第一信号部分之前、或位于所述第一信号部分之内、或位于所述第一信号部分之后。
这种情况下，多个同步信号中不同的同步序列的长度可以为相同的，每个同步信号的长度根据实际情况配置，比如，可以固定为8个比特的长度，或者可以更长或更短，这里不做穷举。多个同步信号中不同的同步序列的具体内容可以是相同的，具体可以根据实际情况设置，只要通信双方预先协商好即可，这里不对其进行限定。
示例性的，所述同步序列的数量可以为2个，这2个同步序列可以如图7所示表示为“SYNC 1”和“SYNC 2”，这两个同步序列“SYNC 1”和“SYNC 2”，均位于所述第一信号部分之内。这里需要指出的是，由于第一信号部分携带所述图7中的数据(data)即目标信息，因此，虽然图7中将两个同步序列“SYNC 1”和“SYNC 2”添加在数据(data)中，但不代表是在目标信息中添加了“SYNC 1”和“SYNC 2”，可以理解为在第一信号部分之内的两个任意时域位置处添加了“SYNC 1”和“SYNC 2”。
所述第一信号部分，还用于携带逆向比特，所述逆向比特用于确定包络检测门限。其中，逆向比特可以表示为“inverse bit”。
所述逆向比特，位于所述目标信息的部分比特位中。
所述逆向比特，可以是在所述目标信息中每隔指定数量个比特位的位置处添加的。所述指定数量可以根据实际情况设置，比如可以是10、20、或更多或更少，这里不做穷举。
或者，所述逆向比特，可以是在所述目标信息中，存在超过预设比特数量门限值个取值相同的连续比特位的情况下，在该连续比特位中任意位置处添加的。其中，所述预设比特数量门限值可以根据实际情况设置，比如10个、16个、20个，或更多或更少，这里不对其进行穷举。
所述逆向比特的数量可以为一个或多个，这里不对其进行限定。
比如，可以在所述目标信息中每隔指定数量个比特位的位置处，添加与该位置相邻的比特位的取值相反取值的逆向比特。
再进一步地，所述逆向比特的取值与所述目标信息的部分比特位的比特值不同。比如，所述逆向比特添加在连续的多个取值为1的比特位中的时候，该逆向比特为0；反之，所述逆向比特添加在连续的多个取值为0的比特位中的时候，该逆向比特为1。假设所述预设比特数量门限值可以为10，也就是说，所述目标信息中有连续传输11个或更多取值为1的部分比特位的时候，可以在这部分比特位中任意的位置处添加逆向比特0。比如，可以在部分比特位中连续添加2个逆向比特0，或者添加1个逆向比特0，这里不对其数量进行限定。
这是由于WUS可以是所述网络设备采用ASK或FSK方式调制得到的信号，在其连续传输较多相同比特值的情况下，可能会导致终端设备(具体为终端设备的第一部件)无法正确检测得到正确信号，也就是可能会出现终端设备(具体为终端设备的第一部件)无法确定当前使用的包络检测门限是否正确的问题。因此，所述网络设备通过在所述目标信息的部分比特中(比如连续传输较多相同比特值的比特位中)，增加上述逆向比特，以辅助终端设备(具体为终端设备的第一部件)确定包络检测门限，保证所述终端设备(具体为终端设备的第一部件)可以解析到正确的目标信息，进而保证所述终端设备(具体为终端设备的第一部件)正确解析所述WUS的全部N个信号部分。
以上为针对所述WUS的第一信号部分的详细说明。在一种可能的实施方式中，所述WUS的所述N个信号部分，除了上述所述第一信号部分之外，还可以包括其他信号部分，下面进一步进行说明：
所述N个信号部分，还包含以下至少之一：
第二信号部分，所述第二信号部分用于携带第一信号序列，所述第一信号序列用于指示WUS的起始位置；
第三信号部分，所述第三信号部分用于携带前导序列，所述前导序列用于进行时钟同步；
第四信号部分，所述第四信号部分用于携带循环冗余校验码(CRC，Cyclic Redundancy Check)；
第五信号部分，所述第五信号部分用于携带第二信号序列，所述第二信号序列用于指示WUS的结束位置。
分别来说，所述第二信号部分用于携带第一信号序列；其中，所述第一信号序列可以如图6和图7所示，具体为“SOW”即Start Of WUS(唤醒信号的起始)。
所述第一信号序列的长度可以根据实际情况设置，比如，所述第一信号序列的长度可以为固定值，比如4bit，或更长或更短，这里不对其进行限定。
所述第一信号序列的具体内容，可以根据实际情况设置，只要通信双方预先确认具备相同含义即可。比如，所述第一信号序列具体可以为一种特殊的或指定的信号序列，如1111，或1010等。由于WUS一般使用OOK调制，因此可以使用特殊的信号序列作为所述第一信号序列，用于表示或指示WUS开始传输，也即表示在SOW(即第一信号序列)之后，为WUS的具体内容开始发送位置。
所述第三信号部分用于携带前导序列。该前导序列如图6或图7所示可以表示为前导序列
(preamble)。
所述前导序列的主要功能是用于进行时钟同步。也就是向所述终端设备的WUR提供时钟同步。
此外，所述前导序列还可以用于指示所述WUS的信号参数；所述WUS的信号参数包括以下至少之一：信号长度、传输速率。
所述前导序列可以仅指示所述信号长度；或者所述前导序列可以仅指示所述传输速率；或者，所述前导序列可以既指示所述信号长度，又指示所述传输速率。
所述信号长度可以指的是所述WUS携带的全部内容的长度，比如240bit(或更长或更短)。
或者，所述信号长度可以可以指的是所述WUS携带的N个信号部分分别对应的长度。
或者，所述信号长度可以指的是：全部N个信号部分中，某一个或多个信号部分的长度。比如，该信号长度仅用于指示第一信号部分的长度为A bit；又比如，该信号长度用于指示第一信号部分的长度为A bit，第二信号部分的长度为B bit等等。
所述传输速率具体可以指的是WUS的传输速率。该传输速率的单位可以为每秒比特率kbps。所述传输速率的具体数值，本实施例不做限定。
所述第四信号部分用于携带循环冗余校验码CRC；比如图6或图7中示意出的CRC。该CRC用于对第一信号部分(即Data)携带的信息进行CRC校验，以检验WUR接收的data部分是否正确。
所述第五信号部分用于携带的第二信号序列；该第二信号序列与前述第一信号序列对应。示例性的，所述第二信号序列，可以如图6或图7所示，表示为EOW(End Of WUS，唤醒信号的结束)，即EOW用于表征WUS的结束位置，或WUS传输结束。
所述第二信号序列的长度可以根据实际情况设置。比如，所述第二信号序列的长度可以为固定值，比如4bit，或更长或更短，这里不对其进行限定。
所述第二信号序列的具体内容可以根据实际情况设置。所述第二信号序列可以是另一种特殊的或指定的信号序列，如“1110”，或“110”等。
应理解，前述实施例中已经说明，所述第一信号序列也为一种特殊的或指定的信号序列。这里，所述第二信号序列与所述第一信号序列可以为不同的特殊的或指定的信号序列，或者，所述第二信号序列与所述第一信号序列可以为相同的特殊的或指定的信号序列。
以上为针对所述WUS中N个信号部分所分别携带的具体信息的详细说明。这里需要进一步说明的是，实际处理中所述WUS除了包含所述第一信号部分之外，可以不包含其他信号部分；或者所述WUS 除了包含所述第一信号部分之外，可以包含其他信号部分中的一部分；或者，所述WUS可以包含上述N个信号部分的全部。均在本实施例的保护范围内。
在一种可能的实施方式中，所述N个信号部分中不同信号部分采用相同的符号长度。或者，所述N个信号部分中至少一个信号部分与其他信号部分采用不同的符号长度。
也就是上述WUS的各个信号部分，使用的符号长度可以是相同的，也可以是不同的。其中，所述符号可以指的是OFDM符号。
关于所述N个信号部分中至少一个信号部分与其他信号部分采用不同的符号长度，可以是上述N个信号部分中M个信号部分采用的符号长度相同均为第一符号长度，剩余N-M个信号部分的符号长度相同均为第二符号长度，其中，第一符号长度与第二符号长度不同。M为小于N的整数。
又或者，所述N个信号部分中至少一个信号部分与其他信号部分采用不同的符号长度，可以是所述N个信号部分中不同信号部分采用不同的符号长度。也就是，任意一个信号部分采用的符号长度与其他信号部分均不相同。
其中，所述不同的符号长度之间的关系可以是指的不同的符号长度之间的比例关系，或倍数关系。比如，第三信号部分中携带的前导序列(preamble)的符号长度是第一信号部分中携带的目标信息的符号长度的1/2。
所述不同的符号长度之间的关系，可以为预设的，或网络设备配置的。所述不同的符号长度之间的关系为网络设备配置的，具体可以是所述网络设备发送第一配置信息，所述第一配置信息用于配置所述不同的符号长度之间的关系。进一步地，所述网络设备可以是在终端设备处于RRC连接态的情况下，向所述终端设备发送所述第一配置信息。其中，所述第一配置信息可以由RRC信令、DCI或系统广播消息中任意之一携带。
以上实施方式中，所述WUS不同的信号部分使用不同的符号长度，能够更加有利于控制不同的信号部分的开销。例如，在preamble的长度(即信息比特数量)一定的情况下，相对使用长的preamble符号长度而言，使用较短的preamble符号长度可以使得preamble所占用的总时间长度较短。
上述实施例中说明了WUS所能够携带的具体信息内容及其格式。进一步地，在网络设备在生成(或监听到)WUS时，可以基于以下三种方式任意之一，传输所述WUS；以使得所述终端设备在接收到WUS的时候可以解析得到每一个比特位的取值，将全部比特位的取值依次组合，可以得到所述WUS的全部内容。以下针对上述三种方式，分别来说：
第一种方式、
上述WUS为二进制启闭键控(OOK，On-Off Keying)信号。所述OOK信号基于移幅键控法(ASK，Amplitude-Shift Keying)或移频键控法(FSK，Frequency-Shift Keying)调制得到。
这种方式中，所述OOK信号的第k个幅度，由第k个比特位的取值确定，k为大于等于1的整数。其中，所述OOK信号的第k个幅度具体可以指的是，所述OOK信号在第k个时刻的幅度。
具体的，所述网络设备在确定第k个比特的取值为第一值的情况下，将所述OOK信号在第k个时刻的幅度设置为第一幅度状态；所述网络设备在确定第k个比特的取值为第二值的情况下，将所述OOK信号在第k个时刻的幅度设置为第二幅度状态。
其中，所述第一幅度状态与第二幅度状态不同，比如，所述第一幅度状态可以为第一幅度值或(比如0)，第二幅度可以为第二幅度值(比如非0)，或者反之亦然。这里，所述第一幅度值(或称为第一幅度状态)可以是网络设备在该对应时刻不发射信号，第二幅度值(或称为第二幅度状态)可以是网络设备在该对应时刻发射信号产生的幅度值。
所述第一值与所述第二值不同，比如，所述第一值为1，所述第二值为0；或者，所述第一值为0，所述第二值为1。
也就是说，在网络设备要传输WUS时，该网络设备可以调制得到OOK信号作为所述WUS，然后发送所述WUS。其中，网络设备可以使用其自身的OOK发射机，直接调制得到或生成OOK信号。具体可以包括：所述网络设备使用其自身的OOK发射机的ASK或FSK调制方式，调制得到或生成所述OOK信号，将所述OOK信号作为所述WUS；然后通过其自身的OOK发射机发射该WUS。上述方式中，可能需要网络设备使用单独的发射机用于发射WUS，并且该网络设备可以保持使用其自身的主发射机发射主系统的信号(如NR为主系统，其信号OFDM信号)。
所述WUS可能占用一段专用的频域资源(或专用的频域资源)；或者所述WUS可能占用一部分主系统(主接收机对应的系统)的频域资源。
第二种方式、
所述WUS为基于OFDM符号上的多个目标子载波生成的OOK信号。
这种方式中，所述网络设备侧可以使用主发射机(或称为OFDM发射机)来生成并传输上述WUS。 所述WUS此时可能占用一部分主系统的频谱(或频域资源)，当然，所述WUS还可能占用一段专用的频谱资源。
上述WUS为基于OFDM符号上的多个目标子载波生成的OOK信号，具体可以指的是：所述WUS为通过生成OFDM波形的方式模拟生成的OOK信号。
进一步地，第i个OFDM符号上的多个目标子载波的状态，由第i个比特位的取值确定；i为大于等于1的整数。其中，所述第i个OFDM符号为前述用于生成OOK信号的OFDM符号中任意之一。所述WUS中的第i个比特位可以为WUS全部比特位中的任意之一。
具体来说所述方法还包括：
所述网络设备在确定第i个比特位的取值为第一值的情况下，将所述第i个OFDM符号上的多个目标子载波置为第一状态；
和/或，
所述网络设备在确定第i个比特位的取值为第二值的情况下，将所述第i个OFDM符号上的多个目标子载波置为第二状态。
其中，所述第i个比特位的取值可以为第一值或第二值。所述第一值与所述第二值不同，比如，所述第一值为1，所述第二值为0；或者，所述第一值为0，所述第二值为1。
所述多个目标子载波置的状态，具体可以指的是多个目标子载波置的幅度或电平。其中，所述多个目标子载波置的状态可以包括第一状态或第二状态。
一种示例中，所述将所述第i个OFDM符号上的多个目标子载波置为第一状态，具体可以指的是：将所述第i个OFDM符号上的所述多个目标子载波均设置为高电平。所述将所述第i个OFDM符号上的多个目标子载波置为第二状态，具体可以指的是：将所述多个目标子载波均设置为低电平。
或者，另一种示例中，所述将所述第i个OFDM符号上的多个目标子载波置为第一状态，具体可以指的是：将所述第i个OFDM符号上的所述多个目标子载波均设置为低电平。所述将所述第i个OFDM符号上的多个目标子载波置为第二状态，具体可以指的是：将所述多个目标子载波均设置为高电平。
其中，所述多个目标子载波，可以为OFDM符号中的部分子载波或者全部子载波。
在所述多个目标子载波为OFDM符号中的部分子载波的情况下，所述多个目标子载波中，不包含中心子载波。也就是说，任意一个OFDM符号上除了中心子载波之外的其他子载波中的至少部分作为上述多个目标子载波。比如，可以是除了中心子载波之外的其他全部子载波均作为所述多个目标子载波；或者，可以是可以是除了中心子载波之外，其他全部子载波中选取至少两个作为所述多个目标子载波。
进一步地，在上述多个目标子载波为所述OFDM符号中的部分子载波的情况中，所述多个目标子载波以所述中心子载波为中心对称分布。比如，图8中示意出OFDM符号中OFDM上的多个目标子载波的数量为4，也就是WUS传输使用的4个目标子载波；进一步地，仍参见图8，WUS传输使用的4个目标子载波，以中心子载波(在图8中表示为黑色背景方形格样式)为中心对称分布。
以图8进行示例性说明，将多个目标子载波设置为第一状态表示为灰色，则图8中最左侧第一列中WUS传输使用的多个目标子载波均置为第一状态(如每一个子载波均设置为高电平，或反之)，此时可以表示WUS中的对应比特位的取值为第一值，比如1。将目标子载波设置为第二状态表示为白色，则图8中最左侧第二列中WUS传输使用的多个目标子载波均置为第二状态(如每一个子载波均设置为低电平，或反之)，此时可以表示WUS中对应比特位的取值为第二值，比如0。另外，图8中除了上述多个目标子载波以及中心子载波之外，还示意出“NR(新无线，New Radio)载波”，该NR载波可以为当前所在的NR主系统的载波，这里不做赘述。
上述中心子载波可以设置为指定状态。也就是，全部OFDM符号中的中心子载波均设置为指定状态。其中，所述指定状态可以根据实际情况设置，比如可以指的是高电平或低电平。示例性的，可以是全部OFDM符号中的中心子载波均设置为高电平(或均设置为低电平)。这样是可以消除直流(DC)子载波的影响。
所述多个目标子载波的子载波间隔，与主系统相同。或者，所述多个目标子载波的子载波间隔，与主系统不同。也就是说，当网络设备在主系统中传输WUS时，WUS的子载波间隔可以与主系统相同或不同。
在所述多个目标子载波的子载波间隔，与主系统不同的情况下，所述多个目标子载波的子载波间隔为网络设备配置的，或预先设置的。相应的，所述方法还包括：所述网络设备发送第二配置信息，所述第二配置信息用于配置所述多个目标子载波的子载波间隔。进一步地，所述网络设备可以是在终端设备处于RRC连接态的情况下，向所述终端设备发送所述第二配置信息。其中，所述第二配置信息可以由RRC信令、DCI或系统广播消息中任意之一携带。
所述OFDM符号不包含循环前缀CP。或者，所述OFDM符号包含循环前缀CP。也就是说，所述 WUS为基于OFDM符号上的多个目标子载波生成的OOK信号，即使用OFDM方式生成WUS信号时，OFDM符号可以没有CP，或者，每一个OFDM符号上均有CP。
一种优选的实施方式中，所述OFDM符号中需要包含CP(尤其是使用ASK调制得到该WUS时)，更有必要使用CP对抗多径衰落，以防止WUS符号间干扰。在所述OFDM符号包含循环前缀CP的情况下，所述CP的长度与主系统的载波至少部分不同。
所述方法还包括：所述网络设备发送第三配置信息，所述第三配置信息用于配置所述CP的长度。进一步地，所述网络设备可以是在终端设备处于RRC连接态的情况下，向所述终端设备发送所述第三配置信息。其中，所述第三配置信息可以由RRC信令、DCI或系统广播消息中任意之一携带。
另外，所述方法还包括：所述网络设备发送第四配置信息，所述第四配置信息用于配置所述多个目标子载波的数量。具体的，所述网络设备可以是在终端设备处于RRC连接态的情况下，向所述终端设备发送所述第四配置信息。其中，所述第四配置信息可以由RRC信令、DCI或系统广播消息中任意之一携带。
具体来说，在基于OFDM符号上的多个目标子载波传输WUS的方式中，所述目标子载波的数量越多，越有利于增强覆盖，也适合于支持大的小区半径。反之，较少的目标子载波的数量适合于支持较少的小区。应理解，在子载波间隔一定的情况下，多个目标子载波正比于WUS所占的带宽。因此，多个目标子载波的灵活配置也等价于WUS所占带宽的灵活配置。
以主系统为NR为例进行说明：在主系统工作于FR1(或称作Sub-6GHz(6GHz以下)频段)时，该主系统的子载波间隔为15KHz或30KHz。在WUS为基于OFDM符号上的多个目标子载波生成的OOK信号的方式中，如果OFDM符号使用与主系统相同的子载波间隔，则峰值速率会不大于14kbps(对应15KHz)或不大于28kbps(对应30KHz)，也就是说在1ms的时长内可传输的比特数为不大于14或者28。如果进一步考虑CRC比特(通常需要多个CRC比特)的开销，如果WUS所需要承载的信息内容较少，是可行的。但如果WUS所需要承载的信息内容较多，这将不能满足WUS信息传输的需求。因此，OFDM符号中的所述多个目标子载波可以使用不同于主系统的子载波间隔。例如，以主系统为NR为例，可在initial(初始)DL(下行，DownLink)BWP(带宽部分，BandWith Part)中传输WUS。为了保证WUS在单位时间内可以携带足够的信息量，WUS的传输速率需要达到一定的要求，例如不低于100kbps。这就要求WUS的载波带宽(当使用OFDM调制时，对应子载波间隔)需要足够大，例如大于100KHz；但另一方面，使用大的子载波间隔会导致CP开销增大，因此，WUS的子载波间隔需要合理的选择，需要考虑其传输速率与CP开销之间的折中。例如子载波间隔120KHz时，对应的OFDM符号时间长度为8.33us(微秒)。而考虑覆盖600m半径的小区，CP长度不能小于2us，此时对应的CP开销为2/(2+8.33)，接近20％。而如果子载波间隔为240KHz时，CP开销将在30％左右(cp2us/(2+4.17)＝30％。可见，对于FR1，选择120KHz的子载波间隔对WUS的传输可能是一个合理的选择。因此，在第二种方式中，所述多个目标子载波的子载波间隔和/或CP长度，可以与主系统的载波不同或至少部分不同。
采用第二种方式，可以存在以下优点：OFDM可以使用FFT方式实现，因此能够与主系统共享FFT变换器，实现复杂度低；在OFDM的多个子载波上发送OOK信号，可以增大OOK信号的发射功率，保证终端设备的接收性能。
第三种方式，
所述WUS为基于单载波生成的OOK信号。
第j个时域位置处的单载波的状态，由第j个比特位的取值确定，j为大于等于1的整数；其中，所述第j个时域位置可以指的是发送该WUS的全部时域位置中的任意之一。
所述方法还包括：
所述网络设备在确定第j个比特位的取值为第一值的情况下，将所述第j个时域位置处的单载波置为第三状态；
和/或，
所述网络设备在确定第j个比特位的取值为第二值的情况下，将所述第j个时域位置处的单载波置为第四状态。
其中，所述比特位的取值可以为第一值或第二值。所述第一值与所述第二值不同，比如，所述第一值为1，所述第二值为0；或者，所述第一值为0，所述第二值为1。
所述单载波的状态具体可以指的是单载波的的幅度或电平。其中，所述多个目标子载波置的状态可以包括第三状态或第四状态。
一种示例中，所述将所述第j个时域位置处的单载波置为第三状态，具体可以指的是：将所述多个目标子载波均设置为低电平。所述将所述第j个时域位置处的单载波置为第四状态，具体可以指的是： 将所述第j个时域位置处的单载波置设置为高电平。
或者，另一种示例中，所述将所述第j个时域位置处的单载波置为第三状态，具体可以指的是：将所述多个目标子载波均设置为高电平。所述将所述第j个时域位置处的单载波置为第四状态，具体可以指的是：将所述第j个时域位置处的单载波置设置为低电平。
需要指出的是，这里所述第三状态与前述第二种方式中的第一状态可以相同或不同，所述第四状态与前述第二种方式中的第二状态可以相同或不同。在一种示例中，所述第三状态为高电平，该高电平的幅度或取值可以大于所述第一状态，所述第四状态的低电平与所述第二状态的低电平可以相同。本实施例不对全部可能的情况进行穷举。
可见，通过采用上述方案，网络设备所发送的WUS中，可以携带N个信号部分，这样可以对WUS所能够携带的内容作出划分，从而在保证终端设备的节能的情况下，还能够在WUS中更加灵活的携带相应的信号部分，从而可以更加灵活的适用于更多的场景。另外，上述方案中还提供了针对WUS的符号长度以及多种传输方式的设计，从而保证了WUS的传输更加合理，适宜在低功耗的多种场景下进行部署。
