首先，对本申请实施例涉及的通信技术进行介绍：
1、零功耗通信简介
零功耗通信可以依托零功耗物联网实现，零功耗物联网也可以称为环境能物联网(Ambient Power Enabled Internet of Things，Ambient IoT/A-IoT)，或者称为无源物联网(Passive IoT)。
采用零功耗通信技术的终端设备可以称为零功耗设备或零功耗物联网设备(Ambient IoT Device/A-IoT Device)。零功耗物联网设备使用各种环境能量，如无线射频能、光能、太阳能、热能、机械能等，来驱动自身的工作。零功耗物联网设备可以没有能量储备能力，也可以具备非常有限的能量储存能力，比如零功耗物联网设备使用几十微法(μF)容量的电容。相比于其它物联网设备，零功耗物联网设备具备免常规电池、免维护、体积尺寸小、低复杂度低成本、长寿命周期等诸多优势。
如图1所示，示出了本申请一个示例性实施例提供的零功耗通信系统100的示意图，零功耗通信系统100包括网络设备120和零功耗设备140。
网络设备120用于向零功耗设备140发送无线供能信号，下行通信信号以及接收零功耗设备140的反向散射信号。零功耗设备140包含能量采集模块141，反向散射通信模块142以及低功耗计算模块143。能量采集模块141可以采集空间中的无线电波携带的能量，用于驱动零功耗设备140的低功耗计算模块143和实现反向散射通信。零功耗设备140获得能量后，可以接收网络设备120的控制信令，并根据控制信令 基于后向散射的方式向网络设备120发送数据。发送数据可以来自于零功耗设备140自身存储的数据(如身份标识或预先写入的信息，如商品的生产日期、品牌、生产厂家等)。
零功耗设备140还可以包括传感器模块144和存储器145。传感器模块144可以包括各类传感器，零功耗设备140可以基于零功耗机制将各类传感器采集的数据上报。存储器145用于存储一些基本信息(如物品标识等)或获取环境温度、环境湿度等传感数据。
零功耗设备140自身不需要电池，同时采用低功耗计算模块143可实现简单的信号解调、解码或编码、调制等简单的运算工作，因此零功耗模块仅需要极简的硬件设计，使得零功耗设备140成本很低、体积很小。
网络设备120包括但不限于：蜂窝网络设备，例如5G/6G网络设备、基站设备；WiFi/WLAN网络设备，例如接入点(Access Point，AP)、路由器、移动接入点等，该移动接入点例如是手机。
零功耗设备140包括但不限于：手持设备、可穿戴设备、车载设备和物联网设备等，零功耗设备140可以是手机、平板电脑、电子书阅读器、膝上便携计算机、台式计算机、电视机、游戏机、增强现实(Augmented Reality，AR)终端、虚拟现实(Virtual Reality，VR)终端和混合现实(Mixed Reality，MR)终端、可穿戴设备、手柄、电子标签和控制器等中的至少一种。
本申请的一些实施例中描述的技术方案可以适用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced Long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、非地面通信网络(Non-Terrestrial Networks，NTN)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、第五代通信(5th-Generation，5G)系统，蜂窝物联网系统，蜂窝无源物联网系统，也可以适用于5G NR系统后续的演进系统，还可以适用于6G以及后续的演进系统。
应当理解，在本申请的一些实施例中，“5G”也可以称为“5G NR”或者“NR”。
应当理解，在本申请实施例的描述中，术语“对应”可表示两者之间具有直接对应或间接对应的关系，也可以表示两者之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。
本申请实施例中，“预定义”可以通过在通信设备(例如零功耗设备、网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。比如预定义可以是指协议中定义的，或指协议中约定的。
2、非连续接收(Discontinuous Reception，DRX)状态
DRX传输机制可以用于终端设备的节能。主要的原理是通过半静态的配置来实现终端设备在时域上的不连续接收。在没有数据传输的时候，终端设备可以通过停止监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)(此时会停止PDCCH盲检)来降低功耗。
DRX可以通过向处于无线资源控制连接态(RRC_Connected)的终端设备配置DRX周期(DRX Cycle)来实现。如图2所示，DRX周期由激活时间(Active Time)和非激活时间(Inactive Time)组成：在激活时间内，终端设备监听并接收PDCCH；在非激活时间内，终端设备不监听且不接收PDCCH以减少功耗。激活时间位于DRX开启之后，或非激活计时器未开启之前，或非激活计时器未到期(Inactive timer not expire)时。
3、休眠(Dormancy)带宽部分(Bandwidth Part，BWP)或休眠载波
网络设备可以将某一个BWP、或某多个BWP、或某一个载波、或某多个载波配置为休眠状态。网络设备可以根据当前的系统吞吐量、业务需求等调整处于休眠状态的BWP或载波。处于休眠状态的BWP可以简称为休眠BWP，处于休眠状态的载波可以简称为休眠载波。
示例性的，网络设备通过指示BWP的切换来使得终端设备工作在休眠BWP或非休眠BWP上。
当终端设备工作在处于休眠状态的BWP或载波上时，终端设备无需监听PDCCH或减少对PDCCH的监听。并且，终端设备可以只保持一些基本的信号接收，比如用于信道测量的信号、用于上下行同步的信号、用于频率校准的信号，等等。
如图3所示，终端设备工作在休眠BWP或休眠载波时可以大幅度降低功耗。
4、基于唤醒接收机(Wake Up Receiver，WUR)的终端节能
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唤醒信号(Wake Up Signal，WUS)。一般情况下传统接收机的功耗大于100毫瓦，而WUR的功耗可以低于1毫瓦。
WUR并不需要像终端设备的传统接收机那样通过开启或关闭的操作来达到省电的效果，而是可以随 时被WUS激活并接收唤醒信息。WUR接收的WUS通常采用比较简单的调制方式，比如WUS为通过ASK调制形成的包络信号。
包络信号的解调可以基于电磁感应产生的感应电流驱动低功耗电路来完成，或者，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WUR可以是无源或半无源的。包络信号的解调也可以基于WUR的内置的电池或供电系统来完成，因此WUR也可以是有源的。但无论哪种供电方式，WUR相比于传统接收机都极大地降低了功耗。WUR可以和终端设备的传统接收机结合在一起，作为传统接收机的一个附加模块；或者，WUR作为终端设备的一个单独的模块，比如，唤醒功能模块。
如图4所示，示出了一种终端设备的接收机系统的结构框图，其中包括主接收机401和WUR 403。WUR 403接收到唤醒信号后，如果需要开启主接收机401来工作，那么，WUR 403可以向主接收机401发送唤醒信息来唤醒主接收机401。否则，主接收机401可以保持在关闭状态，以节省功耗。
WUR接收的唤醒信号具有低功率接收、低功率检测的特征，因此通常采用简单波形来传输。这样的简单波形如果单载波发送，会产生信号能量过于集中在单一频点的现象，导致信号的鲁棒性较差，信号的频率选择性过强，不利于信号的传输质量和传输效率。
基于上述问题，本申请提出了一种唤醒方法，使得携带唤醒信息的信号在频域上分布较为均匀，避免信号能量的过于集中。
图5示出了本申请一个示例性实施例提供的唤醒方法的流程示意图，该方法由网络设备执行，该方法包括：
步骤510：发送第一信号，第一信号携带用于唤醒至少一个零功耗设备的唤醒信息。
其中，唤醒信息对应的频域资源包括至少两组频域单元组，每组频域单元组包括至少一个频域单元。
频域单元包括载波、带宽部分(Bandwidth Part，BWP)、子带、子信道、PRB、子载波、基于其它频域单位的单元中的至少一种。
在一些实施例中，第一信号携带的唤醒信息用于唤醒一个零功耗设备。可选的，第一信号携带的唤醒信息包括一个或多个部分，该一个或多个部分用于唤醒一个零功耗设备。
在一些实施例中，第一信号携带的唤醒信息用于唤醒多个零功耗设备。可选的，第一信号携带多个唤醒信息，多个唤醒信息与多个零功耗设备一一对应。
在一些实施例中，至少两组频域单元组位于不同的频域位置，也即，至少两组频域单元组分别包括不同的频域单元。可选的，至少两组频域单元组相邻或不相邻。
示例性的，若两组频域单元组不相邻，则意味着两组频域单元组之间存在其它频域资源，或，两组频域单元组之间存在保护间隔(Guard Interval，GI)，或，两组频域单元组之间存在其它频域资源和保护间隔。其中，其它频域资源是除两组频域单元组和保护间隔以外的频域资源。
示例性的，若两组以上的频域单元组不相邻，则意味着其中至少两组频域单元组之间存在其它频域资源，或，其中至少两组频域单元组之间存在保护间隔，或，其中至少两组频域单元组之间存在其它频域资源和保护间隔。其中，其它频域资源是除该两组以上的频域单元组和保护间隔以外的频域资源。
在一些实施例中，每组频域单元组包括一个频域单元，或者，包括多个频域单元。可选的，该多个频域单元是连续的或不连续的。
综上所述，本申请实施例提供的方法，发送的第一信号通过至少两组频域单元组来传输唤醒信息，携带唤醒信息的第一信号在频域上分布较为均匀，避免第一信号的能量过于集中而引起的高峰值功率和干扰问题，有助于提高第一信号的鲁棒性，有助于提高第一信号携带的唤醒信息的传输质量和接收质量。
