本申请实施例中,“协议”可以指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做限定。
接下来,对非连续接收(Discontinuous Reception,DRX)进行介绍:
出于对终端设备节电的考虑,相关通信系统支持DRX机制,其主要原理是通过半静态的配置来实现在时域上的不连续接收信号。在没有数据传输的时候,可以通过停止接收PDCCH来降低功耗。
配置DRX的方法是无线资源控制(Radio Resource Control,RRC)连接态(RRC_CONNECTED)的终端设备配置一个DRX周期(DRX cycle)。图1示出了相关技术提供的非连续接收传输机制的示意图,一个DRX周期由激活期(Active Time)和睡眠期(Inactive Time)组成:在“激活期”内,终端设备监听并接收PDCCH;在“睡眠期”内,终端设备不接收PDCCH以减少功耗。
接下来,对唤醒信号进行介绍:
在相关技术中,DRX机制可以结合唤醒信号使用,终端设备在DRX开启时间(DRX ON duration)之前接收唤醒信号的指示。如图1所示,当终端设备在一个DRX周期内有数据传输时,唤醒信号唤醒终端设备,以在DRX开启时间期间检测PDCCH;当终端设备在一个DRX周期内没有数据传输时,唤醒信号不唤醒终端设备,终端设备在DRX开启时间期间不需要检测PDCCH。与相关DRX机制相比,在终端设备没有数据传输时,终端设备可省略DRX开启时间期间的PDCCH检测,从而实现节能。终端设备在DRX开启时间之前的时间可以被称为非激活时间,终端设备的DRX开启时间可以被称为激活时间。DRX唤醒信号采用和PDCCH类似的波形和结构。
接下来,对接收机系统进行介绍:
图2示出了相关技术提供的接收机系统200的示意图。接收机系统200包括唤醒接收机(Wake-Up Receiver,WUR)210和主接收机(main radio)220。
在一些实施例中,主接收机220可等同理解为主收发信机,或主空口通信单元。
为了进一步节电,引入WUR用于接收唤醒信号。唤醒接收机具有极低成本、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。在其它的方式下,也不排除使用类似传统的接收机方式。总之,唤醒接收机的功耗水平比传统的睡眠模式低几个数量级。一般情况下,传统的接收机的功耗大于100毫瓦,而低功耗的接收机可以低于1毫瓦。
因此,唤醒接收机接收的唤醒信号(Wake Up Signal,WUS)与相关标准定义的基于物理下行控制信道(Physical Downlink Control CHannel,PDCCH)承载的信号的调制方式、波形等不同。唤醒信号可以是通过对载波信号进行振幅键控(Amplitude Shift Keying,ASK)调制的包络信号。包络信号的解调也可通过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。唤醒接收机也可以通过终端设备进行有源供电,无论哪种供电方式,该接收机相比传统接收机极大的降低了功耗,例如WUR可以实现小于1毫瓦的功耗,远低于主接收机几十至几百毫瓦的功耗。唤醒接收机可以和终端设备结合在一起,作为终端设备的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。
如图1所示,初始状态下,唤醒接收机210处于唤醒状态,主接收机220处于关闭状态。唤醒接收机210接收唤醒信号,根据唤醒信号的指示确定是否需要唤醒主接收机220。如果需要唤醒主接收机220,网络设备可以通过发送唤醒信号给唤醒接收机210,由唤醒接收机210在接收到该唤醒信号后唤醒主接收机220。否则,主接收机220保持处于关闭状态。
在一些实施例中,当唤醒信号被发送时,用于指示唤醒;当唤醒信号未被发送时,用于指示不唤醒。
在一些实施例中,当发送携带唤醒指示的唤醒信号时,用于指示唤醒;当发送携带不唤醒指示的唤醒信号时,用于指示不唤醒。
WUR随时可以被WUS激活并接收唤醒信号。例如,WUS信号采用开关键控(On-Off Keying,OOK)调制,OOK调制的原理是将载波信号的幅度调制为非零值(1)和零值(0),分别对应On和Off,用来表示信息比特,OOK又名二进制振幅键控(2-ASK)。比如,将比特1调制为On,0调制为Off。
图3示出了本申请一个示例性实施例提供的通信系统100的示意图,通信系统100包括终端设备110与网络设备120。

示例性的,终端设备110与网络设备120之间存在两种通信场景:上行通信场景与下行通信场景。其中,上行通信是指终端设备110向网络设备120发送信号;下行通信是指网络设备120向终端设备110发送信号。

本申请的一些实施例中,“NR”也可以称为5G NR系统或者5G系统。其中,5G移动通信系统可以包括非独立组网(Non-Standalone,NSA)和/或独立组网(Standalone,SA)。
本申请中实施例提供的技术方案还可以应用于机器类通信(Machine Type Communication,MTC)、机器间通信长期演进技术(Long Term Evolution-Machine,LTE-M)、设备到设备(Device to Device,D2D)网络、机器到机器(Machine to Machine,M2M)网络、物联网(Internet of Things,IoT)网络或者其他网络。其中,IoT网络例如可以包括车联网。其中,车联网系统中的通信方式统称为车到其他设备(Vehicle to X,V2X,X可以代表任何事物),例如,该V2X可以包括:车辆到车辆(Vehicle to Vehicle,V2V)通信、车辆与基础设施(Vehicle to Infrastructure,V2I)通信、车辆与行人之间的通信(Vehicle to Pedestrian,V2P)或车辆与网络(Vehicle to Network,V2N)通信等。
对于支持DRX机制的终端设备,在没有数据传输的情况下,会停止盲检PDCCH从而降低终端设备的功耗。相关技术中,可以通过结合唤醒信号机制,当收到唤醒信号时再进入DRX机制的激活时间,从而达到省电的目的。但是检测该唤醒信号的功耗依然较高,与降低终端设备的功耗的想法矛盾。为此,本申请实施例提供了检测两种唤醒信号中至少之一的方法。
图4示出了本申请一个示例性实施例提供的唤醒信号的检测方法的流程图,该方法由终端设备执行,该方法包括:
步骤410:检测第一唤醒信号和第二唤醒信号中的至少一种。
在一些实施例中,第一唤醒信号的检测耗能低于第二唤醒信号的检测耗能。
在一些实施例中,第一唤醒信号和第二唤醒信号具有如下不同中至少之一:波形不同,配置周期不同,时域位置不同,对应的接收机不同。
在一些实施例中,是否接收到第一唤醒信号和第二唤醒信号用于指示是否启动DRX检测和寻呼(paging)检测。在接收到第一唤醒信号或第二唤醒信号的情况下,表示启动DRX检测和寻呼检测,在未接收到第一唤醒信号和第二唤醒信号的情况下,表示不启动DRX检测和寻呼检测。
在一些实施例中,第一唤醒信号携带第一唤醒指示信息,第二唤醒信号携带第二唤醒指示信息,第一唤醒指示信息和第二唤醒指示信息用于指示是否启动DRX检测和寻呼检测以及启动时间。
在一些实施例中,第一唤醒信号是具有第一波形的信号,第二唤醒信号是具有第二波形的信号;
其中,第一波形是基于单载波调制方式得到的,第二波形是基于多载波调制方式得到的,第一波形和第二波形都是简单波形,采用的调制方式包括幅度调制、频率调制、相位调制等。其中,单载波调制是指在一个固定的频段内只采用一个载波的调制技术,多载波调制是指在一个固定的频段内采用多个载波的调制技术。
图5示出了本申请一个示例性实施例提供的幅度调制的示意图。示例性的,第一唤醒信号对应的信号序列为101010,基于该信号序列对无调制载波进行调制后,得到如图5所示的调制后载波的波形。
在一些实施例中,第一波形包括OOK波形,二进制相位键控(Binary Phase Shift Keying,BSK)波形,ASK波形,频率键控(Frequency Shift Keying,FSK)波形中的至少一种;第二波形包括正交频分多址(Orthogonal Frequency Division Multiplexing,OFDM)波形。
相关技术中,通过使用第二唤醒信号,在收到第二唤醒信号时再进入DRX机制的激活时间(Active Time),从而节省电量。第二唤醒信号具有PDCCH波形,可以称为普通唤醒信号,它的检测耗能较高,会导致提高终端设备的工作耗能。本申请实施例中,通过使用检测耗能更低的第一唤醒信号,可以实现进一步省电的目的。通过使用第二唤醒信号可以覆盖更大的通信区域。结合具体场景检测两种唤醒信号中的至少一种,可以适应不同的信道环境,灵活节能。
图6示出了本申请一个示例性实施例提供的生成第一唤醒信号的示意图。在一些实施例中,第一唤醒指示信息是第一唤醒信号携带的信息,将第一唤醒指示信息转换为长度为K的信号序列,K为大于1的正整数。转换的方式包括上采样、扩频、序列映射中的至少一种。可选的,以序列映射方式对第一唤醒指示信息进行转换的方式中,该序列包括恒包络零自相关(Constant Amplitude Zero Auto Correlation,CAZAC)序列、伪噪声(Pseudo-Noise,PN)序列、Gold序列、M序列、哈达玛(Hadamard)序列中的至少一种。
对转换后的信号序列进行离散傅里叶变换(Discrete Fourier Transform,DFT),形成多个子载波信号。比如,对转换后的信号序列y(n)进行DFT,得到x(1)、x(2)直至x(n)。多个子载波信号通过快速傅里叶逆变换(Invert Fast Fourier Transformation,IFFT)生成第一唤醒信号。第一唤醒信号在时域上的波形表现为第一波形610。可选的,多个子载波信号在进行IFFT之前还可以与其他NR信号复用。可选的,对转换后的信号序列不进行DFT和IFFT,而是直接进行单载波幅度调制,得到第一唤醒信号。
可选的,第一唤醒信号是采用OOK调制得到的。OOK调制是将数字形式的序列,调制成MC-OOK波形的无线信号的过程。
在一些实施例中,第一唤醒信号的调制步骤如下:
步骤1:获取第一唤醒指示信息对应的第一序列。
在一些实施例中,第一序列是如下任意一种:无需编码的原始序列;编码前的原始序列;对原始序列完成编码后的编码序列;对原始序列进行多级编码中的至少一级编码后的编码序列。
在一些实施例中,在第一序列的序列长度不是M的整数倍的情况下,对第一序列进行预处理,得到序列长度是M的整数倍的第二序列。M为在预设时长中传输的OOK符号的个数。该预设时长由蜂窝通信系统或WIFI系统中的基本时域单位来确定。在一些实施例中,该预设时长是t个OFDM符号,t个OFDM符号可以传输M个OOK符号。M为在t个OFDM符号中传输的OOK符号的个数。t的取值为正整数。
步骤2:对第一序列进行划分,得到至少一个序列分段。
在一些实施例中,在对第一序列进行预处理得到第二序列的情况下,对第二序列进行划分,得到至少一个序列分段。
步骤3:对每个序列分段进行OOK调制,得到每个序列分段对应的OOK符号。
在一些实施例中,OOK调制包括:上采样/扩频/序列映射、时频变换、确定子载波的系数、时频逆变换中的至少一个。其中:
上采样/扩频/序列映射,是将一个信号对应的每个信息或元素都重复K次的处理,K为大于1的正整数。以扩频处理为例,假设第一唤醒信号对应的第一唤醒信号序列为{1,0,0,1},扩频因子K=4,则扩频得到{1,1,1,1,0,0,0,0,0,0,0,0,1,1,1,1}。
时频变换,也称DFT,是指将时域上的一个序列变换为若干个采样点的频域数据的处理过程。

基于三种不同方式,在不同情况下检测第一唤醒信号和第二唤醒信号中的至少一种,满足不同通信场景下的需求。
方式一:基于测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种。
在一些实施例中,基于第一测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种;或,基于第二测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种;或,基于第一测量信号和第二测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种;其中,第一测量信号与第一唤醒信号关联,第二测量信号与第二唤醒信号关联。第一测量信号和第二测量信号是参考信号。
在一些实施例中,测量结果包括信号质量,信号质量由信噪比(Signal to Interference plus Noise Ratio,SINR)或信号强度确定。SINR是指信号和噪声的比值,通常用分贝(dB)作为单位,在信噪比的值较大的情况下,表示噪声较少,信号质量较好;在信噪比的值较小的情况下,表示噪声较多,信号质量较差。信号强度是指接收到的信号的强度或功率水平,通常用分贝毫瓦(dBm)作为单位,在信号强度的值较大的情况下,表示信号强度高,在信号强度的值较小的情况下,表示信号强度低。

在一些实施例中,在第一测量信号的信号质量小于第一阈值,且第二测量信号的信号质量小于第二阈值的情况下,启动控制信道的检测;其中,控制信道的检测包括:DRX检测和寻呼检测中的至少之一。在这种情况下,后续不再检测第一唤醒信号和第二唤醒信号,即不使用唤醒信号机制,按照DRX周期启动DRX检测,按照寻呼时机启动寻呼检测。
第一测量信号的信号质量小于第一阈值,且第二测量信号的信号质量小于第二阈值可以表征第一测量信号和第二测量信号检测失败,在此情况下,由于第一唤醒信号和第二唤醒信号大概率检测失败,因此不检测第一唤醒信号和第二唤醒信号,直接启动控制信道的检测。与检测第一唤醒信号和第二唤醒信号后再启动控制信道的检测相比降低了终端设备的功耗。
方式二:基于配置的检测周期,检测第一唤醒信号和第二唤醒信号中的至少一种。

在网络设备预先知道下行数据的到达时间在T1时刻附近,但是具体到达时间未知的情况下,网络设备发送一个第二唤醒信号,使得终端设备进入一个较短的检测周期。当下行数据实际到达时,通过第一唤醒信号快速唤醒终端设备接收下行数据。例如下行数据的到达时间在0时0分0秒附近,配置第二周期为5秒,第一周期为1秒,在第i个第二周期检测到第二唤醒信号的情况下,在第i+1个第二周期内的第三时间段检测第一唤醒信号,i为正整数,从而与一直检测第一唤醒信号和第二唤醒信号相比,功耗更小,并且在存在待传输的数据的情况下,能够立刻传输数据,减少数据的时延。
方式三:基于网络设备发送的指示信令,检测第一唤醒信号和第二唤醒信号中的至少一种。
在一些实施例中,在指示信令用于指示检测第一唤醒信号的情况下,检测第一唤醒信号;在指示信令用于指示检测第二唤醒信号的情况下,检测第二唤醒信号;在指示信令用于指示检测第一唤醒信号和第二唤醒信号的情况下,检测第一唤醒信号和第二唤醒信号。
根据指示信令进行唤醒信号的检测不需要其它设计,更加简单易行。
在一些实施例中,基于网络设备发送的指示信令,检测第一唤醒信号和第二唤醒信号中的至少一种之前,还包括:发送第一测量信号和/或第二测量信号的测量结果,测量结果用于辅助网络设备发送指示信令。
通过将测量结果发送给网络设备,帮助网络设备确定发送的指示信令。例如,在第一测量信号的测量结果表示第一测量信号的信号质量大于第一阈值的情况下,网络设备发送第一指示信令,第一指示信令用于指示终端设备检测第一唤醒信号。
又例如,在第一测量信号的测量结果表示第一测量信号的信号质量小于第一阈值,且第二测量信号的测量结果表示第二测量信号的信号质量小于第二阈值的情况下,网络设备发送第四指示信令,第四指示信令用于指示终端设备启动控制信道的检测。
通过发送测量信号的测量结果,辅助网络设备发送指示信令,从而使得网络设备可以根据测量信号的信号质量,合理地发送指示信令,减少网络设备发送不符合实际的指示信令的情况。例如在第二测量信号的信号质量小于第二阈值的情况下,网络设备不会发送用于指示检测第二唤醒信号的指示信令。
综上所述,本实施例提供的方法通过检测第一唤醒信号和第二唤醒信号中的至少一种;其中,第一唤醒信号的检测耗能低于第二唤醒信号的检测耗能,使用检测耗能更低的第一唤醒信号,降低了终端设备的功耗;使用覆盖面积更广的第二唤醒信号,保证了终端设备的通信范围;结合使用第一唤醒信号和第二唤醒信号,灵活应对不同需求的通信场景。

上述实施例中,图4对应的实施例和图9对应的实施例可以单独实施或组合实施,本申请对此不加以限定。图10示出了本申请一个示例性实施例提供的通信场景的示意图。
在一些实施例中,第一终端设备111和第三终端设备113在第一测量信号的覆盖范围内,第二终端设备112在第二测量信号的覆盖范围内。由于第一测量信号和第一唤醒信号关联,第二测量信号和第二唤醒信号关联,第一测量信号的覆盖范围也是第一唤醒信号的覆盖范围,第二测量信号的覆盖范围也是第二唤 醒信号的覆盖范围。第一终端设备111和第三终端设备113可以检测到第一唤醒信号(第一测量信号)和第二唤醒信号(第二测量信号),第二终端设备112只可以检测到第二唤醒信号(第二测量信号)。
在一些实施例中,第二终端设备112发送第一测量信号和第二测量信号的测量结果。由于未检测到第一测量信号,视为第一测量信号的信号质量第一测量信号的信号质量小于第一阈值;且由于第二测量信号的信号质量大于第二阈值,网络设备120发送第二指示信令,第二指示信令用于指示第二终端设备112检测第二唤醒信号。
在一些实施例中,第二终端设备112只检测第二唤醒信号。为了保证第二终端设备112能及时收到寻呼,在只检测第二唤醒信号的情况下,网络设备向第二终端设备112配置较小的第二周期。
在一些实施例中,第一终端设备111发送第一测量信号和第二测量信号的测量结果。由于第一测量信号的信号质量大于第一阈值,且第二测量信号的信号质量大于第二阈值,网络设备120发送第三指示信令,第三指示信令用于指示第一终端设备111检测第一唤醒信号和第二唤醒信号。

示例性的,第一终端设备111在第1个第一周期检测到第二唤醒信号的情况下,在第2个第二周期内的第三时间段检测第一唤醒信号;其中,第三时间段是第一时间段和第二时间段的交集时间段。
在网络设备120预先知道下行数据的到达时间在T1时刻附近,但是具体到达时间未知的情况下,网络设备120发送一个第二唤醒信号,使得第一终端设备111进入一个较短的检测周期。当下行数据实际到达时,通过第一唤醒信号快速唤醒第一终端设备111接收下行数据。例如下行数据的到达时间在0时0分0秒附近,配置第二周期为5秒,第一周期为1秒,在第i个第二周期检测到第二唤醒信号的情况下,在第i+1个第二周期内的第三时间段检测第一唤醒信号,i为正整数,从而与一直检测第一唤醒信号和第二唤醒信号相比,功耗更小,并且在存在待传输的数据的情况下,能够立刻传输数据,减少数据的时延。

综上所述,网络设备120基于终端设备发送的测量信号的测量结果,在不同的场景下合理地发送不同的唤醒信号,从而降低终端设备的功耗。

在本实施例的一种可能设计中,第一测量信号具有的波形与图6中的波形610类似,采用的信号序列包括CAZAC序列、PN序列、Gold序列、M序列、哈达玛(Hadamard)序列中的至少一种。

根据第一测量信号和/或第二测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种,在测量信号的信号质量较高的情况下检测对应的唤醒信号,提高检测成功率。
在本实施例的一种可能设计中,检测模块1110,用于在第一测量信号的信号质量大于第一阈值的情况下,检测第一唤醒信号;在第一测量信号的信号质量小于第一阈值的情况下,检测第二唤醒信号。

通过比较测量信号的信号质量与不同阈值的大小情况,选择检测第一唤醒信号和/或第二唤醒信号,从而降低检测耗能。
在本实施例的一种可能设计中,检测模块1110,还用于在第一测量信号的信号质量小于第一阈值,且第二测量信号的信号质量小于第二阈值的情况下,启动控制信道的检测;其中,控制信道的检测包括:DRX检测和寻呼检测中的至少之一。在这种情况下,后续不再检测第一唤醒信号和第二唤醒信号,即不使用唤醒信号机制,按照DRX周期启动DRX检测,按照寻呼时机启动寻呼检测。
第一测量信号的信号质量小于第一阈值,且第二测量信号的信号质量小于第二阈值可以表征第一测量信号和第二测量信号检测失败,在此情况下,由于第一唤醒信号和第二唤醒信号大概率检测失败,因此不检测第一唤醒信号和第二唤醒信号,直接启动控制信道的检测。与检测第一唤醒信号和第二唤醒信号后再启动控制信道的检测相比降低了唤醒信号的检测装置的功耗。
方式二:基于配置的检测周期,检测第一唤醒信号和第二唤醒信号中的至少一种。

在本实施例的一种可能设计中,第一周期大于第二周期;第一周期包括第一时间段,第一时间段是用于检测第一唤醒信号的时间段;第二周期包括第二时间段,第二时间段是用于检测第二唤醒信号的时间段。
图7示出了本申请一个示例性实施例提供的第一周期和第二周期的示意图。其中,每个第一周期内包括一个第一时间段,每个第二周期内包括一个第二时间段。
在本实施例的一种可能设计中,检测模块1110,用于在第i个第一周期检测到第一唤醒信号的情况下,在第i+1个第一周期内的第三时间段检测第二唤醒信号;其中,第三时间段是第一时间段和第二时间段的交集时间段,i为正整数。
示例性的,当i=1时,在第1个第一周期检测到第一唤醒信号的情况下,在第2个第一周期内的第三时间段检测第二唤醒信号。如图7所示,在黑色方块表示的两个第三时间段检测第二唤醒信号。
由于一般情况下不检测第二唤醒信号,在检测到第一唤醒信号后才检测第二唤醒信号,与一直检测第二唤醒信号相比更加省电,降低唤醒信号的检测装置的功耗。
在本实施例的一种可能设计中,检测周期包括第一周期和第二周期;检测模块1110,用于基于第二周期检测第二唤醒信号;在检测到第二唤醒信号的情况下,基于第一周期检测第一唤醒信号;其中,第一周期与第一唤醒信号关联,第二周期与第二唤醒信号关联。

图8示出了本申请一个示例性实施例提供的第一周期和第二周期的示意图。其中,每个第一周期内包括一个第一时间段,每个第二周期内包括一个第二时间段。
在本实施例的一种可能设计中,检测模块1110,用于在第i个第二周期检测到第二唤醒信号的情况下,在第i+1个第二周期内的第三时间段检测第一唤醒信号;其中,第三时间段是第一时间段和第二时间段的交集时间段,i为正整数。
示例性的,当i=1时,在第1个第二周期检测到第二唤醒信号的情况下,在第2个第二周期内的第三时间段检测第一唤醒信号。如图8所示,在黑色方块表示的两个第三时间段检测第一唤醒信号。
在唤醒信号的发送装置预先知道下行数据的到达时间在T1时刻附近,但是具体到达时间未知的情况下,唤醒信号的发送装置发送一个第二唤醒信号,使得唤醒信号的检测装置进入一个较短的检测周期。当下行数据实际到达时,通过第一唤醒信号快速唤醒唤醒信号的检测装置接收下行数据。例如下行数据的到 达时间在0时0分0秒附近,配置第二周期为5秒,第一周期为1秒,在第i个第二周期检测到第二唤醒信号的情况下,在第i+1个第二周期内的第三时间段检测第一唤醒信号,i为正整数,从而与一直检测第一唤醒信号和第二唤醒信号相比,功耗更小,并且在存在待传输的数据的情况下,能够立刻传输数据,减少数据的时延。
方式三:基于唤醒信号的发送装置发送的指示信令,检测第一唤醒信号和第二唤醒信号中的至少一种。
在本实施例的一种可能设计中,检测模块1110,用于在指示信令用于指示检测第一唤醒信号的情况下,检测第一唤醒信号;在指示信令用于指示检测第二唤醒信号的情况下,检测第二唤醒信号;在指示信令用于指示检测第一唤醒信号和第二唤醒信号的情况下,检测第一唤醒信号和第二唤醒信号。
根据指示信令进行唤醒信号的检测不需要其它设计,更加简单易行。
在本实施例的一种可能设计中,发送模块1120,用于发送第一测量信号和/或第二测量信号的测量结果,测量结果用于辅助唤醒信号的发送装置发送指示信令。
通过将测量结果发送给唤醒信号的发送装置,帮助唤醒信号的发送装置确定发送的指示信令。例如,在第一测量信号的测量结果表示第一测量信号的信号质量大于第一阈值的情况下,唤醒信号的发送装置发送第一指示信令,第一指示信令用于指示唤醒信号的检测装置检测第一唤醒信号。
又例如,在第一测量信号的测量结果表示第一测量信号的信号质量小于第一阈值,且第二测量信号的测量结果表示第二测量信号的信号质量小于第二阈值的情况下,唤醒信号的发送装置发送第四指示信令,第四指示信令用于指示唤醒信号的检测装置启动控制信道的检测。
通过发送测量信号的测量结果,辅助唤醒信号的发送装置发送指示信令,从而使得唤醒信号的发送装置可以根据测量信号的信号质量,合理地发送指示信令,减少唤醒信号的发送装置发送不符合实际的指示信令的情况。例如在第二测量信号的信号质量小于第二阈值的情况下,唤醒信号的发送装置不会发送用于指示检测第二唤醒信号的指示信令。
在本实施例中,检测模块1110可以拆分为至少一个检测子模块,每个检测子模块用于执行上述至少一个检测步骤,例如第一检测子模块,第二检测子模块、第三检测子模块。第一检测子模块用于基于测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种,第二检测子模块用于基于配置的检测周期,检测第一唤醒信号和第二唤醒信号中的至少一种,第三检测子模块用于基于唤醒信号的发送装置发送的指示信令,检测第一唤醒信号和第二唤醒信号中的至少一种;或者第一检测子模块用于基于配置的检测周期,检测第一唤醒信号和第二唤醒信号中的至少一种,第二检测子模块用于基于唤醒信号的发送装置发送的指示信令,检测第一唤醒信号和第二唤醒信号中的至少一种,第三检测子模块用于基于测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种;或者第一检测子模块用于基于唤醒信号的发送装置发送的指示信令,检测第一唤醒信号和第二唤醒信号中的至少一种,第二检测子模块用于基于测量信号的测量结果,检测第一唤醒信号和第二唤醒信号中的至少一种,第三检测子模块用于基于配置的检测周期,检测第一唤醒信号和第二唤醒信号中的至少一种。本实施例对不同检测子模块的功能不加以限定。

可选的,第一唤醒信号是采用OOK调制得到的。OOK调制是将数字形式的序列,调制成MC-OOK波形的无线信号的过程。
