本申请实施例涉及通信领域，并且，更具体地，涉及信息发送的方法和装置。
背景技术
为了满足物联网极低能耗和高速传输的需求，无线系统中引入了双无线设备的设计，一个终端设备包括主连接无线电(primary connection radio,PCR)和伴随无线电(companion connection radio，CCR)，主连接无线电也可以称为主收发信机，伴随无线电工作在低功耗状态，用于检测来自其他设备的寻呼消息或唤醒信息，通常也称为唤醒无线电(wake up radio,WUR)。当伴随无线电检测到需要唤醒主连接无线电进行数据通信的寻呼消息或者唤醒信息时，唤醒主连接无线电与其他设备进行通信。在唤醒过程中，接入点设备(access point，AP)或者网络设备，发送唤醒帧给伴随无线电，在唤醒帧使用频谱的同时，其他设备不能使用频谱，造成频谱资源的浪费。

其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
本申请中的网络设备也可以称为无线接入网(radio access network，RAN)，能够管理无线资源。主要是提供无线接入服务，调度无线资源给接入的终端设备，提供可靠的无线传输协议和数据加密协议等，并能够完成数据在终端设备和核心网之间的转发。
示例性地，本申请实施例中的网络设备可以是用于与用户设备通信的任意一种具有无线收发功能的通信设备，可以是部署在卫星上的通信设备，也可以是部署在地面上的通信设备，或者为设置于该通信设备的芯片。该网络设备包括但不限于：演进型节点B(evolved  Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home evolved nodeB，HeNB，或home node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如NR系统中的gNB，或传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责实时协议和服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。RRC层的信息由CU生成，最终会经过DU的PHY层封装变成PHY层信息，或者，来自终端设备的RRC层信息，被封装成物理层信息，经过空口传输给DU的物理层，再恢复成RRC层信息。因而，在这种架构下，高层信令如RRC层信令，也可以认为是由DU发送/接收的，或者，由DU+AAU发送/接收的。此外，可以将CU划分为接入网中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
为更好的理解本申请实施例，首先介绍一下唤醒相关技术。
在无线通信系统中，终端设备大部分能量浪费在信道监听，即当终端设备无消息收发时，若终端设备持续监听信道，则会消耗大量的能量。为了减少能量的浪费，可以让终端设备处于休眠状态，但处于休眠状态太长，会增加信息处理/传输时延，因此，终端设备必须能够在低功耗、低延迟状态下运行。WUR架构应运而生，其核心思想是：终端设备除包含传统的主要通信接收机外，还包括唤醒接收机部分。平常主要通信接收机关闭，利用唤醒接收机检测来自其他设备的寻呼消息或者唤醒信息，当唤醒接收机检测到需要唤醒主要通信接收机进行数据通信的寻呼消息或者唤醒信息，唤醒主要通信接收机与其他设备进行通信。唤醒接收机可以称为低功率接收机(Lower power receiver，LPR)，或者称为低功率唤醒接收机(Low power wake up receiver，LPWUR)，或者称为低功率无线设备(low power radio,也简称LPR)，或者称为低功率唤醒无线设备(Low power wake up radio，也简称LPWUR)，由于唤醒radio仅仅有接收功能，所以，采用radio或者reciever概念对于唤醒设备而言，没有本质差别。由于唤醒接收机驻留功耗非常低，因此可以起到节省终端设备功耗的效果。
为了降低功耗，唤醒接收机接收的唤醒信息对应的调制方式通常比较简单，例如通断键控(On-Off Keying，OOK)，OOK通过是否发送信号表示比特信息的取值，例如ON表示比特信息取值为”1”，OFF表示比特信息取值为”0”，或者反之。这样接收机只需要经过简单的包络检测就可以识别信号，不需要复杂的基带处理。
对低数据速率场景，比特信息取值为“1”编码为1010，对应OOK调制后的脉冲样式为ON-OFF-ON-OFF，比特信息取值为“0”编码为0101，对应OOK调制后的脉冲样式为OFF-ON-OFF-ON，每个调制后的符号时长为4us，则每个比特信息用4个OOK符号，即16us传输；对高数据速率场景，比特信息取值为“1”编码为10，对应OOK调制后的脉冲样式为ON-OFF，比特信息取值为“0”编码为01，对应OOK调制后的样式为OFF-ON，每个调制后的符号时长2us，则每个比特信息用4us传输。在通信系统中，频谱资源非常宝贵，而用于WUR的信息为OOK信号，以上述高速率场景为例，唤醒带宽占用4MHz的情况下，唤醒的比特速率最高为1bit/16us＝250kbps，频谱效率为1bit/16us/4MHz＝0.0156bit/s/Hz，用宝贵的频谱传输如此低的数据信息，降低了频谱使用效率。
鉴于此，如图3所示，本申请提出一种发送信息的方法300，方法300包括：
步骤S310，第一设备确定样式信息，该样式信息用于指示在第一期间的N个时间单元的各个时间单元上是否发送脉冲，所述样式信息还用于指示第二设备的唤醒信息。
具体的，样式信息指示在第一期间的N个时间单元中的K个时间单元上发送脉冲，在第一期间的剩余N-K个时间单元上不发送脉冲。其中，该K个时间单元可以是连续的，也可以是离散的。一个连续的脉冲对应的时间单元可以是一个，也可以是多个，例如，一个脉冲可以对应2个时间单元，在该2个时间单元上，发送能量均大于0，或一个脉冲可以对应更多时间单元。同样的，不发脉冲的时间单元可以是连续的，也可以是离散的。
样式信息由所述N个时间单元中每个时间单元的样式信息构成，该样式信息为ON/OFF样式信息，其中，N个时间单元中第i个时间单元的ON/OFF样式信息为ON，则代表第一设备在第i个时间单元发送脉冲，所述第i个时间单元的所述ON/OFF样式信息为OFF代表第一设备在第i个时间单元不发送脉冲，i为小于等于N的正整数。是否发送脉冲也可以理解为发送的能量是否为0，当发送能量大于0时代表发送脉冲，当发送能量等于0时代表不发送脉冲。举例来说，例如样式信息为ON OFF ON ON，则代表该样式信息指示了N＝4个时间单元上的脉冲情况，其中第一个，第三个，第四个时间单元上第一设备发送脉冲，第二个时间单元上第一设备不发送脉冲。
可选的，第一期间的N个时间单元的各个时间单元上是否发送脉冲可以理解为在各个时间单元上第一设备是否发送第一信号。
可选的，对应有脉冲的K个时间单元为K个第一时间单元，N-K个没有脉冲的时间单元为该N-K个第二时间单元，则第一时间单元与第二时间单元的区别包括以下至少一项：
第一时间单元上有数据/信令/参考信号传输，第二时间单元上没有数据/信令/参考信号传输；
第一时间单元为有能量传输的OFDM符号，第二时间单元为没有能量传输的OFDM符号；
在时间单元上，接收设备可以检测到能量高于某一门限值，在第二时间单元上，接收设备没有检测到能量高于某一门限值；
第一设备在第一时间单元的能量高于第二时间单元的能量，或者
第一设备在第一时间单元的能量高于第一门限值，在第二时间单元的能量低于第二门限值，第一门限值可以与第二门限值相同或不同。
具体的，第一设备根据是否要唤醒第二设备确定样式信息。例如，当第一设备需要唤醒第二设备时，则确定样式信息为样式信息A，第一设备在样式信息A指示发送脉冲的时间单元上发送脉冲，在样式信息A指示不发送脉冲的时间单元上不发送脉冲。
第一设备确定样式信息的过程具体可以包括：
1)第一设备根据是否要唤醒第二设备确定第二设备的唤醒信息，第二设备的唤醒信息为比特序列；
2)第一设备根据唤醒信息和唤醒信息的脉冲调制方式确定样式信息；唤醒信息的脉冲调制方式指示比特序列中的比特取值与N个时间单元中至少一个时间单元的ON/OFF样式信息的对应关系，其中，ON指示发送脉冲，OFF指示不发送脉冲。
唤醒信息脉冲调制方式可以指示比特序列取值与ON/OFF样式信息的对应关系。可以通过脉冲的宽度，位置，幅度大小或其组合来表示不同的比特信息，本质上是网络设备与终端设备之间约定的如何用脉冲表达信息。图4示出了几种脉冲调制方式的方式。
方式1：用脉冲的有无表示不同的信息，例如用ON表示二进制比特”1”，用OFF表示二进制比特”0”，反之亦可，即用ON表示二进制比特”0”，用OFF表示二进制比特“1”。图4中(a)为时间单元为1时间单元时的信息表示示意图。
方式2：用脉冲的宽度表示不同的信息。例如，用4个时间单元都不发送脉冲表示二进制比特“00”，即用OFF-OFF-OFF-OFF表示比特“00”，脉冲的宽度为1个时间单元表示二进制比特”01”，即用ON-OFF-OFF-OFF表示比特“01”；用脉冲宽度为2时间单元表示二进制比特”10”，即用ON-ON-OFF-OFF表示比特“10”，此时一个脉冲在时域上对应两个时间单元，即脉冲的宽度为2个时间单元；用脉冲宽度为3个时间单元表示二进制比特“11”，即用ON-ON-ON-OFF表示比特“11，如图4中(b)所示。如果全部发OFF看为脉冲宽度为0，则方式1也可以看作是方式2的一种特殊形式。
方式3：用脉冲的位置表示不同的信息，例如ON脉冲在前表示二进制比特”1”，OFF脉冲在前表示”0”，反之亦可。如图4中(c)所示，长度为2个时间单元，ON脉冲宽度为1时间单元的信息指示示意图。再例如，如图4中(d)所示，用ON脉冲在四个时间单元中的第一个时间单元表示二进制比特”00”，用ON脉冲在四个时间单元中的第二个时间单元表示二进制比特”01”，用ON脉冲在四个时间单元中的第三个时间单元表示二进制比特”10”，用ON脉冲在四单元的第四个时间单元表示二进制比特”11”。
方式4：用脉冲的位置和宽度的组合表示不同的信息。例如图4中(e)所示，用ON-OFF-OFF-OFF表示比特“00”，用ON-ON-OFF-OFF表示比特“01”，用OFF-OFF-ON-ON表示比特“10”，用OFF-OFF-OFF-ON表示比特“11”。
方式5：用脉冲的不同幅度表示不同的信息，例如用脉冲幅度为0.25表示二进制比特00，脉冲幅度为0.5为01，脉冲幅度为0.75为10，脉冲幅度为1表示二进制比特11，如图4中(f)所示。脉冲幅度为0可以用于表示信息，故方式1也可以看成是脉冲幅度调制的一种形式。
时间单元为表示时间长度的单位，具体的，一个时间单元可以是一个正交频分复用 (orthogonal frequency division multiplexing，OFDM)符号，或者半个OFDM符号，或者1/4个OFDM符号，一个时间单元还可以包括OFDM符号和该符号对应的循环前缀(cyclic prefix,CP)，或者一个时间单元的长度记为n*Tc，其中，Tc为时间单位，其取值可以与OFDM子载波间隔Δf和快速傅里叶变换(fast Fourier transform，FFT)点数N_f有关，例如T c＝1/(Δf·N f)，例如，Δf为480kHz,N_f＝4096。或者，Δf为312.5kHz,N_f＝64。时间单元的长度还可以用绝对时间来表示，例如1个时间单元长度为1微秒。本申请实施例对时间单元的表示方法和长度不作限制。
步骤S320，第一设备向第三设备发送样式信息，第三设备接收来自第一设备的样式信息。
第三设备根据接收到的样式信息，确定在第一期间的哪些时间单元可以接收到来自第一设备的信息，在对应的时间单元进行信息的接收，在样式信息指示无脉冲发送的时间单元不进行信息的接收，从而有效提升信息接收的效率，避免在无信号发送的时间单元进行信息接收造成的能量浪费。
第一期间可以是协议预定义的一个时间段，例如直接定义第一期间的开始时刻和结束时刻，或者预定义好第一期间的开始时刻和持续时间；或者第一期间可以是第一设备发送的信令指示的，例如通过RRC信令对第一期间的开始时刻以及持续时间进行指示，可选的，还可以进一步指示第一期间对应的周期。
S320为可选步骤。比如，第一设备也可以不向第三设备发送样式信息，此时，第三设备可以在第一期间的N个时间单元的各个时间单元都进行信号的接收，再根据接收信号的能量大小和/或信号质量剔除接收信号能量低/信号质量差的符号。这种方式可以节省第一设备向第三设备发送样式信息的信令。
步骤S330，第一设备在K个时间单元上向第二设备和第三设备发送第一信号，该K个时间单元属于N个时间单元，且该K个时间单元为样式信息指示发送脉冲的时间单元，第一信号用于承载发送给第三设备的参考信号和/或数据信息，其中，N，K为正整数，且K小于或等于N。
第一设备在N-K个时间单元上发送功率为0，其中，该N-K个时间单元属于第一期间的N个时间单元，且该N-K个时间单元为样式信息指示不发送脉冲的时间单元。
第一设备，在样式信息指示发送脉冲的时间单元上发送第一信号，第一信号用于承载发送给第三设备的参考信号和/或数据信息。其中，参考信号包括信道状态信息参考信号(channel state information reference signal，CSI-RS)和定位参考信号(positioning reference signal，PRS)中的至少一种，CSI-RS用于测量信道状态信息，定位参考信号用于定位，数据信息包括用户数据信息和/或控制信令。
可以理解的，上述第一设备向第二设备和第三设备发送第一信号，并不是第一设备分别向第二设备和第三设备发送了第一信号。而是第一设备将第一信号发送出去，第二设备和第三设备都会尝试接收。并根据接收的信号进行后续处理。
步骤S340，第三设备接收第一信号。
在第一设备向第三设备发送了样式信息时，第三设备根据样式信息在N个时间单元中的K个时间单元上接收来自第一设备的第一信号，根据第一信号获取来自第一设备的参考信号和/或数据信息。
当步骤S320为可选步骤，第一设备没有向第三设备发送样式信息时，第三设备根据N个时间单元的每个时间单元接收信号的能量大小和/或信号质量，确定哪个时间单元第一设备发送了第一信号，哪个时间单元第一设备没有发送第一信号，并在确定为发送了第一信号的那些时间单元接收来自第一设备的第一信号，根据第一信号获取第三设备的参考信号和/或数据信息。
当第一信号承载的信息中包括参考信号时，参考信号可以包括CSI-RS，PRS中的至少一种。例如，如果参考信号是CSI-RS，则第三设备在第一期间的K个时间单元的部分或全部时间单元上可以进行信道状态测量，即第三设备在接收第一信号的同时可以利用第一信号中的参考信号进行测量。如果参考信号是PRS，则第三设备可以在第一期间的K个时间单元的部分或全部时间单元上进行定位测量。在进行定位测量时，需要获得无线电波的到达时间，到达角度等，用于测量终端位置。通常，需要获得来自多个小区的信号才可以获得位置信息。
进一步的，由于第一期间的N个时间单元中，有N-K个时间单元上无脉冲发送，第三设备可以在该N-K个时间单元的部分或者全部时间单元上，进行干扰测量，或者进行干扰测量，或者用于规避对其他设备的干扰。
步骤S350，第二设备根据接收到的来自第一设备的脉冲，确定是否唤醒。
第二设备也可称为唤醒设备，唤醒设备也可以称为WUR设备。
可以理解的，对于第二设备而言，脉冲即为来自第一设备的第一信号。
第二设备在唤醒信息接收机会接收来自第一设备的脉冲，其中，唤醒信息接收机会包括第一期间。唤醒信号接收机会包括M个时间单元，第一期间包括N个时间单元，M大于或等于N，唤醒信号接收机会的M个时间单元中的N个时间单元上是否接收到脉冲用于指示样式信息。或者，第二设备在第一期间的N个时间单元上接收来自第一设备的脉冲，第一期间内的所述N个时间单元的每个时间单元上是否接收到脉冲用于指示样式信息。可以理解，唤醒信息接收机会在第一设备侧可以称为唤醒信息发送机会，第一信号接收机会在第一设备侧可以称为第一信号发送机会。
第二设备根据样式信息，确定是否唤醒。
第二设备根据第一期间的N个时间单元上的脉冲的接收情况确定样式信息，从而确定是否唤醒设备。当第二设备在N个时间单元的其中一个时间单元上检测到能量信号，或者在该时间单元检测到的功率大于0，或者在该时间单元接收到的能量大于一个阈值，则第二设备认为该时间单元上接收到脉冲，从而确定该时间单元对应的ON/OFF样式信息为ON。同理，当第二设备在该时间单元未检测到能量信号，或者在该时间单元检测到的功率等于0，或者在该时间单元未接收到第一信号，或者在该时间单元接收到的能量小于一个阈值，则第二设备认为未该时间单元接收到脉冲，从而确定对应的ON/OFF样式信息为OFF。第二设备可以逐一确定第一期间的N个时间单元上的各个时间单元的ON/OFF样式信息，从而确定样式信息，并进一步确定是否唤醒。
例如，N＝4时，第二设备在4个时间单元上的第一个时间单元以及第三个时间单元上接收到脉冲，而在第二个时间单元以及第四个时间单元上未接收到脉冲，则样式信息对应为ON-OFF-ON-OFF，第二设备根据ON-OFF-ON-OFF的样式信息进一步确定是否进行唤 醒。示例性的，确定是否唤醒的方式可以包括如下几种。
方式一，第二设备根据样式信息确定是否进行唤醒。第一设备与第二设备之间，即网络设备与终端设备之间可以提前约定样式信息与是否唤醒之间的对应关系。例如，样式信息包括样式信息A与样式信息B，分别对应唤醒设备与不唤醒设备，当第二设备根据接收到的脉冲情况确定样式信息为样式信息A，则代表对设备进行唤醒；当第二设备根据接收到的脉冲情况确定样式信息为样式信息B，则代表不对设备进行唤醒。例如，当预定义ON-OFF-ON-OFF样式代表唤醒设备，则第二设备根据接收到的来自第一设备的脉冲的情况确定样式信息为ON-OFF-ON-OFF时，第二设备确定对设备进行唤醒。除样式信息A及样式信息B之外，还可以有更多的样式信息。
通过样式信息与是否唤醒之前的对应关系，第二设备只需要在第一期间进行信息接收并确定第一期间的N个时间单元上各个时间单元对应的ON/OFF样式，即可确定是否唤醒。
方式二，第二设备根据样式信息，确定唤醒信息，第二设备根据唤醒信息确定是否唤醒。
在该方式下，所述第二终端设备根据所述样式信息，确定唤醒信息，包括：
唤醒信息为比特序列，第二设备根据样式信息和唤醒信息的脉冲调制方式，确定唤醒信息，其中，脉冲调制方式指示比特序列中的比特取值与N个时间单元中至少一个时间单元的ON/OFF样式的对应关系。同样可以参见图4，当第二设备确定样式信息之后，即确定了一系列ON-OFF样式(pattern)之后，可以根据脉冲调制方式，确定该样式信息对应的二进制比特序列，该确定出的比特序列即为第二设备的唤醒信息。
例如，当采用图4中(a)所示的调制方式，当第二设备确定样式信息为ON-OFF-ON-OFF时，则确定唤醒信息为“1010”。当采用图4中(c)所示的调制方式，当第二设备确定样式信息为ON-OFF-ON-OFF时，则确定唤醒信息为“01”。以上以N＝4进行举例，实际的第一期间的时间单元个数N不限定，其对应的比特序列的长度也不限定，调制方式也不限定。
以下对唤醒信息的组成和结构进行介绍。
唤醒信息由唤醒数据信息构成；或者唤醒信息由唤醒数据信息和唤醒同步信息构成。
其中，唤醒数据信息包括唤醒消息内容，唤醒数据信息还包括以下中的至少一项：唤醒区域标识，唤醒小区标识，循环冗余码校验。
下面对唤醒数据信息包括的信息进行描述：
唤醒区域标识：也可称为WUR区域标识，用于指示唤醒设备可以驻留在WUR状态不唤醒主设备的移动区域。当WUR设备检测到新的WUR区域标识时，认为WUR设备移动移动出之前所驻留的WUR区域，此时唤醒主radio，可以进行小区重选。如图5所示，小区1，小区2，小区3构成一个WUR区域1，小区4，小区5，小区6构成另一个WUR区域2。当WUR设备从WUR区域1移动到WUR区域2时，需要唤醒主radio即进行小区重选。
唤醒小区标识：也可称为WUR小区标识，用于指示唤醒设备的主设备服务的小区。当WUR设备检测到新的WUR小区时，认为WUR设备移动移动出之前所驻留的WUR 小区，此时可以唤醒主radio，可以进行小区重选。
唤醒消息内容：又可称为WUR唤醒信息，用于指示唤醒的信息。具体的，可以为表1中的一个取值。其中，如果表示第一设备在该唤醒信息接收时间不唤醒任何设备，则可以采用事先约定的某个序列，例如序列1，或者可以用除特定标识外的其他内容表示不唤醒。例如不是小区标识、组标识、设备标识中的任何一个数，则表示不唤醒。
表1
Figure PCTCN2022136913-appb-000001
再例如，唤醒消息内容可以为表2中的一个取值。其中，用序列2表示唤醒设备，用序列1或者非序列2的其他任何内容，表示不唤醒。
表2
信息内容 含义
序列1/非序列2 不唤醒
序列2 唤醒
计数器：用于指示第一设备系统信息是否发生更新，每次第一设备系统消息发生更新，计数器加1，计数到最大值后重新回到0。计数器可以用于WUR设备来判断第一设备是否更新了系统消息。检测到计数器发生变化，表示要唤醒主radio接收系统消息。可以仅在与唤醒设备配置信息有关的系统信息更新的时候计数器才发生变更，其他系统消息变更不需要更新计数器，这样更利用第二设备节能。
循环冗余校验CRC：用于对前述信息进行校验。根据唤醒信息传输信息量，唤醒信息传输可靠性要求等，可以确定CRC的校验比特数。例如，CRC的比特数可以为6，11，16或24比特。CRC的计算方式详见3GPP协议TS 38.212 vg.7.0 5.1节。
唤醒信息可以仅由唤醒数据信息构成，唤醒数据信息可以仅包括唤醒消息内容，此时，可以直接用唤醒消息内容所对应的序列同时实现同步和唤醒的功能，唤醒设备通过检测事先实现约定的数据信息实现同步功能，这种方式可以节省信令，增加唤醒消息内容所对应的序列的长度，从而提升唤醒信息接收可靠性。
唤醒同步信息包括同步信号，可以使得第二设备，即唤醒设备能够找到WUR的开始时间，避免误检。唤醒同步信息具体可以为同步序列，且同步序列可以设计为固定的一个序列，则可以降低检测复杂度。
举例来说，同步信息可以为预先约定的序列，例如同步序列为{0101，1011，0100，0100,1110,1000,1100，0111}，WUR设备可以首先检测同步序列，如果发现同步信号序列能量低于一定的门限，则可以认为WUR设备移动出唤醒区域，从而自动唤醒主设备。
唤醒信息由唤醒数据信息和唤醒同步信息构成时，唤醒数据信息和唤醒同步信息可以 分别采用不同的脉冲调制方式，例如唤醒同步信息采用如图4中(a)所示的调制方式，唤醒数据信息可以采用如图4中(c)所示的调制方式，或者唤醒数据信息和唤醒同步信息采用相同的脉冲调制方式，例如都采用如图4中(a)所示的调制方式。
可选的，唤醒信息中的信息可以进行重复，例如，唤醒同步信息可以包括重复的同步序列，通过重复传输，可以提升信息接收的可靠性。当唤醒信息为比特序列时，对该比特序列也可以进行重复，例如，当唤醒信息为比特序列“0110”时，可以对该4比特进行扩充，例如对每一位进行重复得到“00,11,11,00”，或者对每一位进行取反重复，例如生成“01,10,10,01”，或者进行序列重复，例如对序列重复得到“0110,0110”，或者对序列取反重复得到“0110,1001”。以上以4比特为例进行说明，实际唤醒信息中的比特可以大于4比特或者小于4比特，本申请对此并不限定。唤醒设备在接收到脉冲后，可以根据预定义的规则进行合并恢复唤醒信息。通过这种设计，可以有效提升覆盖性能，提升传输的可靠性。
图6A-图6D示出了为唤醒信息组成的几种示例。在下面的例子中，子载波间隔Δf＝2 μ·15[kHz]。
情况A.如图6A所示，在一种示例中，第一期间时间为1ms，取μ＝4，即子载波间隔Δf＝240kHz,采用3GPP 38.211V g.7.0所定义的扩展CP，则1ms内有符号
Figure PCTCN2022136913-appb-000002
个，两个符号的ON-OFF样式对能够传递1比特信息，一个ON/OFF样式称为一个ON/OFF样式对，1ms内共能够有96个ON/OFF样式对，则1ms能够传输96比特信息，其中，唤醒同步信息为32比特，WUR区域标识、WUR小区标识、唤醒消息内容和CRC分别占用16比特。采用较大的子载波间隔可以降低脉冲宽度，减少每比特信息的时间，以便提升传输效率，采用扩展CP，一方面是为了降低唤醒信息接收复杂度，因为3GPP 38.211V g.7.0所定义的一般CP(Normal CP)时，每个时隙中，第一个符号的长度与其他符号的长度不同，另一方面，扩展CP的长度大于一般CP，采用扩展CP相对normal CP也可以提升覆盖，因为长CP用于感知时，可以支持更大的时延扩展。
情况B.在一种示例中，第一期间为1ms，取μ＝3，即子载波间隔Δf＝120kHz,采用扩展CP，第一期间为1ms，则1m内有
Figure PCTCN2022136913-appb-000003
个符号，两个符号传递1比特信息，上图中一个ON/OFF波形称为一个ON/OFF样式对，1ms内共能够有48个ON/OFF样式对，则在1ms可以传输48比特信息，其中，WUR小区标识、唤醒消息内容分别占用16比特，计数器占用4比特，CRC占用12比特。在这一种示例性系统中，我们在唤醒信息时间内不承载唤醒同步信息，而用WUR小区标识同时兼做同步功能。这种设计包含了计数器，每次第一设备系统信息发生更新，计数器加1。计数器可以用于WUR设备来判断第一设备是否更新了系统消息。检测到计数器发生变化，则唤醒主radio接收系统消息。如图6B所示为本申请所示的一种具体的WUR格式实施方法。
情况C.在一种示例中，第一期间为1ms，取μ＝2，即子载波间隔Δf＝60kHz,采用扩展CP，第一期间为1ms，则1m内有
Figure PCTCN2022136913-appb-000004
个符号，两个符号传递1比特信息，上图中一个ON/OFF波形称为一个ON/OFF样式对，1ms内共能够有24个ON/OFF样式对。只发送唤醒消息内容，唤醒消息内容为24bit长的序列，该序列取序列1表示唤醒，取序列2表示不唤醒。如图6C所示为本申请所示的一种具体的WUR格式实施方法。
情况D.在一种示例中，第一期间为1ms，取μ＝2，即子载波间隔Δf＝60kHz,采用扩展CP，第一期间为1ms，则1m内有
Figure PCTCN2022136913-appb-000005
个符号，两个符号传递1比特信息，上图中一个ON/OFF波形称为一个ON/OFF样式对，1ms内共能够有24个ON/OFF样式对。用20比特表示唤醒消息内容，用4比特承载计数器。唤醒消息内容和计数器的作用如上文所述。如图6D所示为本申请所示的一种具体的WUR格式实施方法。
通过上述方法，第一设备在向第三设备发送参考信号和/或数据信号的同时实现了向第二设备传递唤醒信息，第二设备根据第一信号的接收情况(样式，pattern)确定是否唤醒，第三设备根据第一信号获取参考信号和/或数据信息，并可进一步使用参考信号进行感知测量等过程，或者获得第一信号中承载的数据信息，从而在该系统中有效提升了频谱的使用效率，实现感知与唤醒的一体化，通信与唤醒的一体化。
本申请还提供一种发送信号的方法400，如图7所示，方法400包括：
步骤S410.1，第一设备向第二设备发送唤醒信息配置信息。相应的，第二设备接收唤醒信息配置信息。
唤醒信息配置信息用于指示唤醒信息接收机会(wake up oppotunity)，唤醒信息配置信息包括唤醒信息接收机会的时域信息和/或唤醒信息接收机会的频域信息，唤醒信息接收机会的时域信息包括唤醒信息接收机会的开始时间，唤醒信息接收机会的周期，以及唤醒信息接收机会的持续时间。
可以参见图8描述，唤醒信息配置信息指示了开始时间以及每个周期中的唤醒信息的持续时间，以及唤醒信息接收机会的周期。则第二设备即唤醒设备可以根据唤醒信息配置信息计算每个周期中唤醒信息接收机会的开始时间及结束时间。
可以理解的，唤醒信息接收机会还可以称为针对第二设备的唤醒信息发送机会，即第一设备向第二设备发送唤醒信息的机会。
步骤S410.2，第一设备向第三设备发送第一信号配置信息。相应的，第三设备接收第一信号配置信息。
第一信号配置信息用于指示第一信号接收机会，第一信号配置信息包括第一信号接收机会的时域信息和/或第一信号发送期的频域信息，第一信号接收机会的时间信息包括第一信号接收机会的开始时间，第一信号接收机会的周期，以及第一信号接收机会的持续时间。
同样可以参见图7的描述，第三设备根据第一信号配置信息可以确定开始时间及持续时间以及对应的周期。从而可以确定各个周期中第一信号的开始和结束时间。
可选的，当第一信号配置信息指示的第一信号接收机会与唤醒信息配置信息指示的唤醒信息接收机会在某个周期内在时域上完全重叠时，即二者的开始时间相同，结束时间也相同，则第一期间的开始时间与结束时间与唤醒信息和第一信号的开始时间、结束时间均相同。当第一信号接收机会开始时间与唤醒信息接收机会开始时间不完全相同时，例如图9中所示，则第一期间包括在第一信号接收机会持续时间内，第一期间包括N个时间单元，第一信号接收机会持续时间为P个时间单元，则N小于P，在P个时间单元中的P-N个时间单元上，第一设备也向第三设备发送第一信号，或第一信号的一部分，第三设备在第一信号配置信息指示的第一信号接收机会开始时间即开始进行第一信号的接收，接收期包 括了第一期间的N个时间单元，即可以理解为在第一期间发送的第一信号为第一设备发给第三设备的第一信号的一部分。第三设备根据P个时间单元上的接收的信息确定第一信号，确定参考信息和/或数据信息。同理，如图9中所示，唤醒信息接收机会持续时间为M个时间单元，M大于N，即一个周期中，唤醒信息接收机会完全包括第一期间的N个时间单元时，在M个时间单元中的其他M-N个时间单元上，第一设备也可以根据是否唤醒第二设备确定各个时间单元上是否发送脉冲，第二设备可以根据M个时间单元上整体的脉冲接收情况确定是否唤醒。
第一期间为至少一个唤醒信息接收机会的时域资源与至少一个第一信号接收机会的时域资源的重叠部分。或者可以理解为，第一期间为唤醒信息接收机会的至少一个周期中时域资源与第一信号接收机会的至少一个周期中时域资源的重叠部分。
可选的，第一期间也是周期性的，其周期与第一信号接收机会的周期一致。因此，当唤醒信息接收机会的周期是第一信号接收机会的周期的整数倍时，对于第二设备即唤醒设备，在唤醒信息不同周期内，第一期间相对于唤醒信息接收机会的位置相同，对于第三设备而言，在第一信号的不同周期内，第一期间相对于第一信号接收机会的位置相同。
参见图9，一个唤醒周期内的唤醒信息接收机会与一个第一信号接收机会周期内的第一信号接收机会在时域上重叠，则其在时域上的重叠部分即为第一期间，包括N个时间单元。
第一期间与至少一个唤醒信息接收机会的时域资源全部重叠或部分重叠，第一期间与至少一个第一信号接收机会的时域资源全部重叠或部分重叠。或者可以理解为第一期间与第一信号接收机会的至少一个周期中的时域资源全部重叠或者部分重叠，第一期间与唤醒信息接收机会的至少一个周期中的时域资源全部重叠或者部分重叠。当三者全部重叠的时候，即代表在唤醒周期内，唤醒信息接收机会的持续时间等于第一信号接收机会的持续时间，该两个持续时间等于N个时间单元，同时唤醒信息接收机会的开始时间等于第一信号接收机会的开始时间，唤醒信息接收机会的结束时间等于第一信号接收机会的结束时间。第一期间是周期性的，其周期与第一信号的周期相同。
可选的，唤醒信息接收机会的周期为第一信号接收机会的周期的整数倍。若唤醒信息对应的周期为第一周期，第一信号对应的周期为第二周期，第一周期可以为第二周期的整数倍。即唤醒信息发送的间隔比参考信号和/或数据信号发送的间隔更长，减少了唤醒信息对应的资源占用。
如图10所示，第二设备(例如，UEA)的唤醒信息接收机会周期为第三设备的第一信号接收机会周期的整数倍，在第一个第一信号接收机会周期内，UEA的唤醒信息接收机会在时域上与第一信号接收机会有重叠，该重叠部分为第一期间。在第二个第一信号接收机会周期内，第五设备(例如，UEB)的唤醒信息接收机会与第一信号接收机会在时域上有重叠，则此时，二者的重叠部分也可以称为第一期间，UEB可以在这个第一期间内接收来自第一设备的脉冲，根据接收情况确定是否唤醒。
因此，当一个终端设备的唤醒信息周期是其他终端设备第一信号周期的整数倍的时候，可以引入多个唤醒设备，在不同的第一信号的周期内，可以指示不同唤醒设备是否唤醒， 进一步提升系统频谱的利用率。
可以理解的，第一信号接收机会还可以称为针对第三设备的第一信号发送机会，即第一设备向第三设备发送第一信号的机会。
唤醒信息接收机会的频域信息指示唤醒信息所占的第一频域带宽，第一信号接收机会的频域信息指示第一信号所占的第二频域带宽，其中，第一频域带宽小于或等于第二频域带宽，第二频域带宽小于或等于系统带宽。第一信号对应带宽大于唤醒信息对应带宽，可以提升第一信号接收精度，例如提升感知精度，唤醒信息对应的带宽较窄，可以降低功耗。
如图11所示，第一信号占用的第二频域带宽可以是唤醒信息占用的第一频域带宽的整数倍。则在第一信号的频带内，可以通知多个唤醒设备的相关唤醒信息。频域资源可以用起始频率所在位置和感知信号带宽来表示，或者可以用中心频率所在位置和感知带宽来表示，或者可以用起始频率位置和结束频率位置来表示，或者第一设备可以将系统带宽分为几个子信道(Subchannel)或带宽部分(Bandwidth Part)，用子信道编号(subchannel index)或带宽部分编号(Bandwidth Part Index)来表示。
步骤S410.3，第一设备向第二设备发送干扰测量配置信息；

步骤S420.1第二设备确定唤醒信息接收机会；
第二设备根据唤醒信息配置信息，确定唤醒信息接收机会。该唤醒信息接收机会，包 括第一期间，但第二设备并不需要确定第一期间，第一期间对唤醒设备而言是透明的。
唤醒信息接收机会，包括第一期间，具体为，第一期间与唤醒信息接收机会的至少一个周期中的时域资源全部重叠或部分重叠。
步骤S420.2第三设备确定第一信号接收机会；

第一设备根据唤醒信息，确定第一期间的脉冲发送样式。
在第一期间与唤醒信息接收机会部分重叠时(参见附图9和附图10)，样式信息用于指示在第一期间内的脉冲发送样式。例如唤醒信息接收机会持续时间为8符号，唤醒信息为10011010，采用附图4中(a)所示的调制方式，唤醒信息脉冲样式为：ON-OFF-OFF-ON-ON-OFF-ON-OFF，其中，第一个符号到第6个符号为第一期间，则样式信息仅包括该6个符号的脉冲发送样式。例如用比特图bitmap表示样式信息，用“1”表示发脉冲，用“0”表示不发脉冲，则此时的用于表示样式信息的比特图为“100110”。

第二设备根据在唤醒信息接收机会的脉冲接收情况确定是否唤醒。在唤醒信息接收机会与第一期间全部重叠时，第二设备根据第一期间内的脉冲接收情况确定是否唤醒。
在唤醒信息接收机会与第一期间部分重叠时，第二设备根据在第一期间的脉冲接收情况和在唤醒信息接收机会所包括的第一期间之外的脉冲接收情况，确定是否唤醒。
步骤S470.第三设备根据样式信息接收第一信号。
步骤S480.第四设备根据样式信息进行干扰测量。具体的，在N-K个时间单元的部分或者全部上进行干扰测量。
在上述实施方法中，第三设备和第四设备在上述实施例中为可选的，也就是说，可以不包括步骤S410.2、S420.3、S440.1、S470，或不包括步骤S410.3、S420.4、S440.2、S480。
应理解，上述步骤仅为一种具体的实施方法，实际执行的步骤并不一定严格按照上面的顺序。
可选的，该方法还可以包括，在步骤S410.1之前：
第一设备接收来自第二设备的进入唤醒模式请求信息，进入WUR模式请求还可以包括第二设备建议的唤醒信息配置信息。
第一设备向第二设备发送进入唤醒模式响应信息。唤醒信息配置信息可以承载在该唤醒模式响应信息中。
第二设备接收第一设备的唤醒模式响应信息，如果确认第一设备同意第二设备进入WUR模式，则按照第一设备的响应信息配置WUR设备，并进入WUR模式。
第二设备可以通过RRC信令发送进入WUR模式请求，例如通过UE辅助信息发送进入WUR模式请求和/或第二设备建议的唤醒信息配置信息。采用UE辅助信息发送进入WUR模式请求和/或第二设备建议的唤醒信息配置信息，可以更好的兼容现有的协议。
具体的唤醒设备(即第二设备)可以在判断满足进入低功耗接收状态时，通过唤醒设备的主radio向主radio的服务小区(即第一设备)发起进入WUR模式的请求，所谓的WUR模式，指设备关闭主radio，通过WUR设备接收唤醒信息的工作模式，其中，唤醒设备综合考虑下面至少一个或多个因素来判断是否进入低功耗接收状态：
1)唤醒设备所处的状态。优选的，唤醒设备在IDLE状态，或者在IN-ACTIVE状态，更适合进入WUR模式
2)唤醒设备的移动速度。优选的，唤醒设备处于低速或静止状态时，更适合进入WUR 模式
3)唤醒设备在小区中的位置。优选的，唤醒设备不处于小区边缘时，更适合进入WUR模式
4)唤醒设备的业务量。优选的，唤醒设备业务量较少，更适合进入WUR模式
5)唤醒设备的业务服务质量要求QoS(Quality of service)，优选的，唤醒设备可以接受较高的时延时，更适合进入WUR模式
6)唤醒设备的功耗。优选的，唤醒设备处于中低电量时，更适合进入WUR模式。
7)唤醒设备的类型。优选的，配置电池容量比较低的设备如可穿戴设备或者抄表等物联网应用类型设备，更适合进入WUR模式。
可选的，在确定第二设备的唤醒信息之前，还包括：
向第二设备发送以下标识中的至少一个：唤醒区域标识、唤醒小区标识、唤醒设备标识、唤醒设备组标识。
第一设备确定标识的过程可以包括：
第一设备为WUR设备分配WUR设备标识和或WUR组标识，具体为，
第一步：确定WUR标识资源池。WUR标识资源池可以根据WUR标识的比特数确定，例如WUR标识的比特为16比特，则第一设备可以确定16比特数中的全部或者一部分为WUR标识资源池。WUR组和WUR设备可以共用一个WUR标识资源池，或者WUR设备和WUR组分别有各自的资源池。例如WUR设备标识为12比特，WUR组标识为4比特，则WUR设设备资源池为12比特数中的全部或部分，WUR组资源池为4比特数中的全部或部分。可以实现预留资源池中的一部分用作特殊的用途，例如可以预留一个标识用于表示广播组。
第二步：从WUR标识资源池中选择一个没有被其他设备使用的标识分配WUR设备。具体的，可以至少有两种方式：
方式1：从WUR标识资源池中随机选择一个没有使用的标识分配给WUR设备。
方式2：第一设备根据邻居设备在同一唤醒信息接收时间内分配使用的WUR标识确定第一设备服务的WUR设备的标识，具体确定方法为，获得邻居设备在同一唤醒信息接收时间内分配的WUR标识，取该标识的二进制表示的每比特的非值作为新的标识。举例来说，如果邻居设备用的WUR标识为1011,1001,0001，则第一设备用的WUR标识为0100,0110,1110，这样的好处是可以将降低感知信号的干扰。
采用方式2时，在确定第二设备的唤醒信息之前，还包括：
获取邻居设备的唤醒信息接收机会配置，包括唤醒信息接收机会时间配置信息和或频域配置信息，获取邻居设备在唤醒信息接收机会所分配的WUR标识。
可选的，在确定第二设备的唤醒信息之前，还包括：
向第二设备发送唤醒信息与序列的对应关系。
所述向第二设备发送唤醒信息与序列的对应关系，其中一种具体实施方法为：
确定唤醒信息格式，唤醒信息由唤醒序列构成；
确定唤醒信息和唤醒序列之间的对应关系，例如序列1表示唤醒，序列2表示不唤醒。或者，序列1表示不唤醒，序列2表示唤醒。
将唤醒信息与序列的对应关系发送给第二设备。相应的，第二设备接收唤醒信息与序列的对应关系。
据此，第二设备在唤醒信息接收机会接收序列1或序列2，并根据唤醒信息与序列的对应关系，确定是否唤醒。
在这种实施方法中，第一设备可以为不同的唤醒设备配置不同的唤醒信息和序列的对应关系，以便进行干扰随机化。或者，第一设备和邻居设备分别为各自服务的唤醒设备配置不同的唤醒信息和序列的对应关系，以便进行干扰规避，即尽量避免相同或相邻资源上发送的信息产生干扰或冲突。
可选的，第四设备可以是第一设备，或者是第三设备，或者也可以是其他设备。第四设备在实施例中是可选的。当第四设备是第一设备，即网络设备时，不需要执行S430.3，即不需要向第四设备发送干扰测量配置信息，第一设备在N-K个时间单元进行回波测量，从而进一步提升了系统的频谱使用效率。
可选的，在本申请所述的实施例中，可以不限定第一信号所承载的内容的接收设备，和/或不限定第一信号所承载的内容，此时，本申请所述的实施方法为一种唤醒信息发送和接收方法，第一期间等于唤醒信息接收机会。
可选的，当上述方法涉及到多个小区时，为了进一步提升感知检测性能，支持感知和唤醒一体化设计的多个小区之间可以进一步进行小区间干扰避免/规避以提升感知性能和唤醒检测性能。
确定与第一设备存在干扰关系的邻居小区集合，可以选择对第一设备干扰最强的小区作为与第一设备存在干扰关系的邻居小区，或者选择第一设备作为干扰源给别的小区造成干扰的小区作为与第一设备存在干扰关系的邻居小区。存在干扰关系的邻居小区集合内的设备，当上述第一信号是参考信号的情况下，第一信号也可以称为感知信号，感知信号与唤醒信息接收的时频资源重叠或者部分重叠。这里的感知信号与唤醒信息接收时频资源重叠或者部分重叠指其在时域上重叠或部分重叠，例如，重叠部分为上述第一期间。在频域上占用的频带为相同或者相邻频域范围。
确定存在干扰关系的邻居小区集合内设备的唤醒信息传输内容，使得在频域上相同或者临近、在时域上占用的时域资源相同的两个小区唤醒信号传输内容按照比特异或后的值的比特1的个数尽可能大，即对于资源上冲突的唤醒信息，唤醒信息的比特序列尽量不同，避免信号干扰。例如存在干扰关系的两个邻居小区分别为cell_i和cell_j，cell_i小区唤醒信号传输内容序列为a_i，cell_j小区唤醒信号传输内容为a_j，a_i和a_j即每个符号的ON/OFF波形的比特表示，用比特1表示ON，用比特0表示OFF。比特异或的规则可以理解为0 1＝1,0 0＝0,1 1＝0，1 0＝1。按比特异或后的值中的比特1的个数尽可能大，其中一种具体的实施方法为，cell_j的各个序列为cell_i各个序列的每比特取”非”后的序列。如表3所示为一种具体举例。以在上述24比特的唤醒消息内容为例，若cell_i用来表示不唤醒任何信息的比特序列1为{0101，1011，0100，0100,1110}，则cell_j用来表示不唤醒任何信息的比特序列1为{1010，0100，1011，1011，0001},若cell_i的小区标识为{1100,0110,1011,0100,1001}，
表3邻居小区唤醒消息内容

如存在干扰关系的邻居小区集合内的小区的个数大于2，则可以根据集合的数量和WUR信息比特数的多少来确定该多个小区的各个WUR信息的具体取值，例如在上述举例中，WUR标识的比特数为20比特，假设小区数为3，每个小区共需要4个序列，涉及3*4＝12个序列，则可以从20比特长的任意二进制序列中，选择12个两两之间码距最大的序列，分别分配给3个小区。这种设计，可以使得在同一个时间单元中，例如符号中，在其中一个小区的符号为ON时，其他小区在该符号为OFF的可能性尽可能大，从而降低感知信号检测的小区间干扰。
进一步的，在上述WUR信息格式举例中，还包括4比特的计数器，为了最小化感知干扰，我们进一步的可以构建4比特计数器的顺序，例如小区cell_i的计数器的内容为实际取值，cell_j的计数器的内容为该实际值按比特取非后的值，0取非后为1。如表4所示。下表以计数器为4比特为例举例，其他计数器比特数也参照相同的规则，即尽可能在一个小区为ON时，其他小区为OFF以便降低感知信号检测的小区间干扰。
