为便于理解本申请实施例,对本申请中涉及到的术语做简单说明。
1、寻呼(paging)
终端设备在空闲(idle)态或者非活动(inactive)态下的时候,可以周期性地接收寻呼。作为示例,终端设备执行接收寻呼的流程包括如下步骤。
1)终端设备可以根据自己的标识(identifier,ID)(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。
2)终端设备在PO内监测物理下行控制信道(physical downlink control channel,PDCCH)(如也可以称为寻呼PDCCH),该PDCCH中包含下行控制信息(downlink control information,DCI)(如也可以称为寻呼DCI)。
3)若终端设备检测到PDCCH,则终端设备在该PDCCH调度的位置接收物理下行共享信道(physical downlink shared channel,PDSCH)(如也可以称为寻呼PDSCH)。寻呼PDSCH中包含寻呼消息(paging message),该寻呼消息可指示哪些终端设备被寻呼到了。作为示例,寻呼PDSCH中最多包含32个寻呼记录(paging record),每个paging record中可以包含一个UE ID,UE ID用于指示哪个UE被寻呼了。
寻呼可分为两类:一类是核心网寻呼(CN paging),另一类是接入网寻呼(RAN paging)。
1)核心网寻呼:指的是UE处于idle态时接收的寻呼,由核心网发起,核心网将被寻呼UE的UE ID发给将要发寻呼信息的网络设备。对于核心网寻呼,UE ID为5G系统架构演进(system architecture evolution,SAE)临时移动用户标识符(5G SAE temporary mobile station identifier,5G-S-TMSI),长度如为48比特。5G-S-TMSI可由接入和移动性管理功能(access and mobility management function,AMF)分配。
2)接入网寻呼:指的是UE处于inactive态时接收的寻呼,由网络设备发起,该网络设备可将被寻呼UE的UE ID发给将要发寻呼信息的其他网络设备。该网络设备为UE由连接态(connected)态转为inactive态时UE所在的小区对应的基站。该小区也可称为最后一个服务小区(last serving cell)。对于接入网寻呼,UE ID为不激活态无线网络临时标识(inactive radio network temporary identifier,I-RNTI),长度如为40比特。I-RNTI可由last serving cell分配。
应理解,上述关于执行寻呼接收的流程仅是示例性说明,例如可以参考相关标准,本申请不予限制。
2、包络检波(envelope-demodulation)与非包络检波
包络检波是非相干解调的一种解调方式。包络检波是通过检测信号的包络来解调或检测信号承载的信息的一种方式。
将一段时间长度的高频信号的峰值点连线,就可以得到表示时间的横坐标上方(正的)一条线和下方(负的)一条线,这两条线就叫包络线。包络线就是反映高频信号幅度变化的曲线。对于等幅高频信号,这两条包络线就是平行线。当用一个低频信号对一个高频信号进行幅度调制(即调幅)时,低频信号就成了高频信号的包络线。
本申请涉及的非包络检波方式可以理解为除包络检波方式以外的解调方式,例如通过相位承载信息,通过检测信号的相位来解调出信号承载的信息。
3、主电路和唤醒电路
一般情况下,无论终端设备在idle态或者inactive态执行接收寻呼的流程时,还是终端设备在连接态进行数据接收时,都是用相同的接收模块,或者用相同的接收机,或者用相同的接收电路。在本申请中,为便于描述,将完成这些功能或执行相关步骤的模块称为主电路。可以理解,主电路仅是为区分做的命名,其具体命名不对本申请的保护范围造成限定。下文为便于说明,统一描述为主电路。
终端设备使用主电路接收的信号可以被称为在主链路上传输,其中,主链路表征了终端设备和网络设备间的一种连接关系,是一个逻辑概念,而非一个物理实体。可以理解,主链路仅是为区分做的命名,其具体命名不对本申请的保护范围造成限定。
当终端设备采用主电路接收寻呼时,功耗较高。例如,终端设备在接收寻呼时,首先要使用主电路的接收模块接收下行信号,然后终端设备还要对PDCCH进行盲检,对接收到的PDSCH进行解码等,这些都会带来较大的功耗。此外,由于主电路较为复杂,其运行时的基准功耗或静态功耗比较高。
为了降低终端设备接收寻呼带来的功耗,一种可能的方法是,终端设备可以使用一个单独的低功耗小电路接收信号,终端设备使用该低功耗小电路接收的信号可称为低功率唤醒信号(low power wake up signal,LP-WUS)或者唤醒信号。作为示例,唤醒信号可用于指示寻呼相关的信息,该寻呼相关的信息例如可以包括:一个终端设备或者一组终端设备是否被寻呼。该低功耗小电路可以使用一个结构简单的单独的小电路或芯片实现,其功耗较低。该低功耗小电路例如可以称为唤醒无线电(wake up radio,WUR),或者也可以称为唤醒电路,或者也可以称为低功耗电路,或者也可以称为唤醒接收机(wake up receiver,WUR),等等,关于其命名,本申请不予限制。在本申请中,为便于描述,将该低功耗小电路称为唤醒电路。可以理解,唤醒电路仅是为区分做的命名,其具体命名不对本申请的保护范围造成限定。下文为便于说明,统一描述为唤醒电路。此外,下文为便于说明,将终端设备使用唤醒电路接收的信号称为唤醒信号。
终端设备使用唤醒电路接收的信号可以被称为在唤醒链路上传输,其中,唤醒链路表征了终端设备和网络设备间的一种连接关系,是一个逻辑概念,而非一个物理实体。可以理解,唤醒链路仅是为区分做的命名,其具体命名不对本申请的保护范围造成限定。
作为示例,图2示出了终端设备通过唤醒电路接收唤醒信号的示意图。
如图2所示,当终端设备使用唤醒电路接收信号时,若终端设备未检测到与自己关联的唤醒信号,则继续使用唤醒电路接收信号,主电路可处于关闭状态或者睡眠状态;若终端设备检测到与自己关联的唤醒信号,则触发主电路的唤醒,即令主电路处于/切换为开启状态,该开启状态也可称为工作状态,或者称为活跃状态。主电路开启后,终端设备可以执行接收寻呼过程,例如,终端设备接收寻呼PDCCH,在自己对应的PO检测到寻呼PDCCH后,接收寻呼PDSCH。或者主电路开启后,终端设备可以直接执行接入流程。此时,唤醒电路接收到的唤醒信号可以直接指示被寻呼的UE,终端设备开启主电路后,不需要再通过主电路接收寻呼,而是直接发起随机接入。
为了保证功耗收益,唤醒信号可采用开关键控(on off key,OOK)调制,或者也可采用移频键控(frequency shift keying,FSK)调制。下面简单介绍一下这两种调制方式。
1)OOK:利用信号的发送与否来调制信息,对应的唤醒电路可采用包络检测的方法接收信号。OOK调制技术可以用复杂度很低的接收机就可以实现解调,故而能实现唤醒电路的低功耗目标。
作为示例,图3示出了唤醒信号采用OOK调制时的波形示意图。
当信号采用OOK调制时,每个比特,即编码后的比特,可对应一个符号(symbol)。一个符号也可以被称为一个码片(chip),也可以被称为其他名称,这里不做限制。
例如,当比特为1时,该符号长度内有信号发出(即该符号长度内信号发射功率不为0);当比特为0时,该符号长度内无信号发出(即该符号长度内信号发射功率为0)。如图3所示,图3所示的波形可代表1010四个比特。
再例如,当比特为0时,该符号长度内有信号发出(即该符号长度内信号发射功率不为0);当比特为1时,该符号长度内无信号发出(即该符号长度内信号发射功率为0)。在该情况下,图3所示的波形可代表0101四个比特。
2)FSK:是一种将信息调制在载波频率上的调制技术。在使用FSK调制时,一个符号可以携带至少一个比特信息。例如,假设需要传输的信息比特为0,1组成的序列,调制的信号在频域有4个可能的位置。举例来说,发送频率为f1的信号代表传输的是比特“00”,发送频率为f2的信号代表传输的是比特“01”,发送频率为f3的信号代表传输的是比特“10”,发送频率为f4的信号代表传输的是比特“11”。在接收端,可以使用鉴频电路,检测接收到的信号频率。若检测到信号频率为f1,则判断接收到的比特为00;若检测到信号频率为f2,则判断接收到的比特为01;若检测到信号频率为f3,则判断接收到的比特为10;若检测到信号频率为f4,则判断接收到的比特为11。
上面对本申请中涉及到的术语做了简单说明,下文实施例中不再赘述。
可以理解,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
下文将结合附图详细说明本申请实施例提供的信息传输的方法。本申请提供的实施例可以应用于上述图1所示的网络架构中,不作限定。本申请实施例提供的信息传输的方法可以由网络设备或网络设备中的芯片系统中的任一个与终端设备或终端设备中的芯片系统中的任一个交互。下面主要以终端设备与网络设备交互进行介绍。
图4示出了本申请提供的信息传输的方法100的示意图。下面分别给出方法100的两种方案。方法100中,以终端设备既支持第一调制方式又支持第二调制方式为例进行说明。
方案1:
S101a,网络设备向终端设备发送基于第一调制方式调制的第一指示信息(为了方便说明,以下称为第一指示信息#1),以及,基于第二调制方式调制的第二指示信息(为了方便说明,以下称为第二指示信息#1);相应地,终端设备通过包络检波的方式接收来自网络设备的基于第一调制方式调制的第一指示信息#1,以及,基于第二调制方式调制的第二指示信息#1。
其中,第一指示信息#1和第二指示信息#1的组合用于指示是否唤醒终端设备。例如,第一指示信息#1和第二指示信息#1可以承载于同一个唤醒信号中,例如上述WUR。
其中,第一调制方式与第二调制方式不同。例如,第一调制方式为开关键控调制方式(OOK),第二调制方式包括移频键控调制方式(FSK)。再例如,第一调制方式为基于一个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号的OOK调制方式,第二调制方式为基于OFDM符号内的时间片段的OOK调制方式。其中,基于一个循环前缀正交频分复用(cyclic prefix OFDM,CP-OFDM)符号的OOK调制方式,通过发送一个OFDM符号表示1,不发送表示0。而基于OFDM符号内的多个时域片段的OOK调制方式中,可以将一个OFDM符号中的非循环前缀正交频分复用(cyclic prefix,CP)样点划分为多个时间码片(chip)或时间片段,通过每个chip上是否发送信号来承载1比特信息。并且,基于OFDM符号内的时间片段的OOK调制方式比基于一个OFDM符号的OOK调制方式的信息速率高。
关于终端设备通过包络检波的方式接收来自网络设备的第一指示信息#1和第二指示信息#1,可以通过以下方式实现。例如,终端设备包括一个单独的低功耗小电路,例如上述唤醒电路。终端设备打开该唤醒电路,检测第一指示信息#1和第二指示信息#1,根据第一调制方式解调出第一指示信息#1,以及,根据第二调制方式解调出第二指示信息#1。
可选地,在相同时间内传输所述第一指示信息#1的比特数小于传输所述第二指示信息#1的比特数。例如,第一调制方式为OOK,第二调制方式为FSK。在相同时间内传输所述第一指示信息#1的比特数与传输所述第二指示信息#1的比特数的比值为k:,N为FSK方式的候选频率位置的个数,N为正整数,k≥1且k为整数。例如,这里的候选频域位置可以是候选子载波。
可选地,在S101a之前,方法100还包括:网络设备生成第一指示信息#1和第二指示信息#1。
S102a,终端设备根据第一指示信息#1和第二指示信息#1的组合确定是否唤醒终端设备。
作为一个示例,终端设备包括一个单独的低功耗小电路,例如上述唤醒电路。终端设备还包括上述主电路。S102a可以理解为,该唤醒电路根据第一指示信息#1和第二指示信息#1的组合确定是否唤醒主电路。可选地,若主电路被唤醒,则使用主电路在PO上接收paging消息或者直接在随机接入(new random access,RACH)资源上发送物理随机接入信道(physical random access channel,PRACH)。
作为一个示例,第一指示信息#1与第二指示信息#1的组合具体通过指示终端设备的标识信息来指示唤醒终端设备。下面终端设备的标识信息以UE ID为例,对第一指示信息#1和第二指示信息#1的组合如何指示终端设备的标识信息,给出几种可能的示例。
示例1-1,第一指示信息#1为该终端设备的UE ID的第一部分,例如UE ID的低16比特。第二指示信息#1为终端设备的UE ID的第二部分,例如UE ID的高32bits。第一指示信息#1与第二指示信息#1的组合可以向终端设备指示UE ID全部48bits信息。
示例1-2,第一指示信息#1为对终端设备的UE ID压缩后的信息。例如,该对UE ID压缩后的信息可以用位图(bitmap)方式表示。或者第一指示信息#1为终端设备所在的寻呼组的ID的信息。第二指示信息#1为终端设备的UE ID。
示例1-3,第一指示信息#1和第二指示信息#1相同,均指示终端设备的UE ID。该示例中,第二指示信息#1能够对第一指示信息#1进行再次确认(double check)。
上述方案,网络设备向终端设备发送分别基于两种不同的调制方式调制的两个指示信息,并通过该两个指示信息来指示是否唤醒终端设备,终端设备通过包络检波的方式接收到这两个指示信息后确定是否要唤醒终端设备。能够实现在通信系统中兼容采用不同调制方式调制或解调的信息,从而协调不同的调制方式的调制效率和功耗,提高资源利用率。进一步地,这两个指示信息承载于一个信号中,相比于网络设备分别发送基于第一调制方式调制的信号和基于第二调制方式调制的信号,能够节省资源开销。
需要说明的是,本申请的方案适用于两种或两种以上不同的调制方式。本申请中均以两种不同的调制方式为例进行说明,但本申请对此不造成限定。在这里进行统一说明,下不赘述。
可选地,终端设备还支持第三调制方式。方法100还包括:网络设备向终端设备发送基于第三调制方式调制的第三指示信息。相应地,终端设备通过非包络检波的方式接收来自网络设备的基于第三调制方式调制的第三指示信息。第三指示信息用于指示终端设备被唤醒后使用的小区广播信息。终端设备被唤醒后可以根据第三指示信息对小区进行测量或接入。
例如,第三指示信息可以是该小区的小区ID,还可以是小区的系统消息的部分信息或者小区系统消息的版本信息,或者系统消息是否发生变更的信息,或者小区范围内是否发生了地震海啸预警等。
例如,第三调制方式包括相位调制方式、幅度调制方式等。
可选地,第一指示信息#1、第二指示信息#1和第三指示信息承载于同一个信号中。
上述方案,使得同一个信号承载更多信息,进一步提高资源利用率。
方案2:
S101b,网络设备向终端设备发送基于第一调制方式调制的第一指示信息#2(为了方便说明,以下称为第一指示信息#2),以及,基于第二调制方式调制的第二指示信息#2(为了方便说明,以下称为第二指示信息#2);相应地,终端设备通过包络检波的方式接收来自网络设备的基于第一调制方式调制的第一指示信息#2,以及,基于第二调制方式调制的第二指示信息#2。
其中,第一指示信息#2用于指示是否唤醒终端设备,第二指示信息#2用于指示终端设备被唤醒后的操作。例如,第一指示信息#2和第二指示信息#2可以承载于同一个唤醒信号中,例如上述WUR。
第一调制方式与第二调制方式不同。具体地,第一调制方式与第二调制方式的可能的示例及相关说明具体可以参见方案1中对应的内容,在此不多赘述。
关于终端设备通过包络检波的方式接收来自网络设备的第一指示信息#2和第二指示信息#2,具体可以参照方案1中终端设备通过包络检波的方式接收来自第一指示信息#1和第二指示信息#1的描述,区别在于,将第一指示信息#1和第二指示信息#1替换为第一指示信息#2和第二指示信息#2。
可选地,在相同时间内传输所述第一指示信息#2的比特数小于传输所述第二指示信息#2的比特数。例如,第一调制方式为OOK,第二调制方式为FSK。在相同时间内传输所述第一指示信息#2的比特数与传输所述第二指示信息#2的比特数的比值为k:,N为RSK方式的候选频率位置的个数,N为正整数,k≥1且k为整数。例如,这里的候选频域位置可以是候选子载波。
可选地,在S101b之前,方法100还包括:网络设备生成第一指示信息#2和第二指示信息#2。
S102b,终端设备根据第一指示信息#2确定是否唤醒所述终端设备。
作为一个示例,终端设备包括一个单独的低功耗小电路,例如上述唤醒电路。终端设备还包括上述主电路。S102b可以理解为,该唤醒电路根据第一指示信息#2确定是否唤醒主电路。可选地,若主电路被唤醒,则使用主电路在PO上接收paging消息或者直接在RACH资源上发送PRACH。
作为一个示例,第一指示信息#2具体通过指示终端设备的标识信息来指示唤醒终端设备。下面终端设备的标识信息以UE ID为例,对第一指示信息#2如何指示终端设备的标识信息,给出几种可能的示例。
示例2-1,第一指示信息#2指示UE ID的全部信息。
示例2-2,第一指示信息#2为对终端设备的UE ID压缩后的信息。例如,该对UE ID压缩后的信息可以用位图(bitmap)方式表示。
可选地,在根据第一指示信息#2确定唤醒终端设备的情况下,方法100还包括:终端设备根据第二指示信息#2确定终端设备被唤醒后的操作。
例如,第二指示信息#2可以是第一小区的标识信息,终端设备根据第二指示信息#2确定终端设备被唤醒后在第一小区与网络设备通信。
再例如,第二指示信息#2可以是指示终端唤醒后直接发起RACH接入还是需要读取寻呼信息,终端设备根据第二指示信息#2确定终端设备被唤醒后通过读取RACH配置信息后直接发起随机接入流程,还是需要先接收所述终端的PO上发送的寻呼消息。
上述方案,网络设备向终端设备发送分别基于两种不同的调制方式调制的两个指示信息,并通过该两个指示信息中的第一指示信息用于指示是否唤醒终端设备,通过该两个指示信息中的第二指示信息指示终端设备被唤醒后的操作。终端设备通过包络检波的方式接收到这两个指示信息后确定是否要唤醒终端设备。在确定要唤醒终端设备的情况下,还能够根据第二指示信息确定终端设备被唤醒后的操作。能够实现在通信系统中兼容采用不同调制方式调制或解调的信息,从而协调不同的调制方式的调制效率和功耗。进一步地,这两个指示信息承载于一个信号中,相比于网络设备分别发送基于第一调制方式调制的信号和基于第二调制方式调制的信号,能够节省资源开销。
可选地,终端设备还支持第三调制方式。方法100还包括:网络设备向终端设备发送基于第三调制方式调制的第三指示信息。相应地,终端设备通过非包络检波的方式接收来自网络设备的基于第三调制方式调制的第三指示信息。其中,第三指示信息用于指示终端设备被唤醒后使用的小区广播信息。终端设备被唤醒后可以根据第三指示信息对小区进行测量或接入。
例如,第三指示信息可以是该小区的小区ID,还可以是小区的系统消息的部分信息或者小区系统消息的版本信息,或者系统消息是否发生变更的信息,或者小区范围内是否发生了地震海啸预警等。
例如,第三调制方式包括相位调制方式、幅度调制方式等。
可选地,第一指示信息#2、第二指示信息#2和第三指示信息承载于同一个信号中。
上述方案,使得同一个信号承载更多信息,进一步提高资源利用率。
图5示出了本申请提供的信息传输的方法200的示意图。方法200中,以终端设备支持第一调制方式,不支持第二调制方式为例进行说明。对于网络设备而言,方法200可以与方法300结合,或者,方法200与方法300可以单独实施。
S201,网络设备向终端设备发送基于第一调制方式调制的第一指示信息(为方便说明,以下称为第一指示信息#3),以及,基于第二调制方式调制的第二指示信息(为方便说明,以下称为第二指示信息#3);相应地,终端设备通过包络检波的方式接收来自网络设备的基于第一调制方式调制的第一指示信息#3。
例如,第一指示信息#3和第二指示信息#3可以承载于同一个唤醒信号中,例如上述WUR。
一种可能的实现方式中,S201中的第一指示信息#3和第二指示信息#3分别可以理解为方法100中的第一指示信息#1和第二指示信息#1,并且可以参照方法100中的相关描述。
另一种可能的实现方式中,S201中的第一指示信息#3和第二指示信息#3分别可以理解为方法100中的第一指示信息#2和第二指示信息#2,并且可以参照方法100中的相关描述。
可选地,在S201之前,方法100还包括:网络设备生成第一指示信息#3和第二指示信息#3。
关于第一调制方式和第二调制方式的可能的示例和对应的说明可以参见方法100中对应的描述。
关于终端设备通过包络检波的方式接收来自网络设备的第一指示信息#3,可以通过以下方式实现。例如,终端设备包括一个单独的低功耗小电路,例如上述唤醒电路。终端设备打开该唤醒电路,检测第一指示信息#3,根据第一调制方式解调出第一指示信息#3。
S202,终端设备根据第一指示信息确定是否唤醒所述终端设备。
作为一个示例,终端设备包括一个单独的低功耗小电路,例如上述唤醒电路。终端设备还包括上述主电路。S202可以理解为,该唤醒电路根据第一指示信息#3确定是否唤醒主电路。可选地,若主电路被唤醒,则使用主电路在PO上接收paging消息或者直接在RACH资源上发送PRACH。
上述方案,网络设备向终端设备发送基于不同调制方式调制的指示信息,终端设备能够根据支持的调制方式解调出第一指示信息,并根据第一指示信息确定是否唤醒终端设备。从而,能够实现网络设备向支持一种或多种调制方式的终端设备发送同样的指示信息,均能够指示是否唤醒终端设备。从而,使得采用不同调制方式调制或解调的信息的通信系统也能够兼容仅支持一种调制方式的终端设备,可以避免对所有终端设备都要求支持不同的调制方式,降低终端设备的复杂度。同时,能够避免网络设备向支持不同调制方式的终端设备发送不同的指示信息,减少网络设备处理的复杂度。
下面结合图6介绍本申请提供的信息传输的方法300。方法300可以理解为方法100中的方案1的进一步具体示例。其中,以第一调制方式为OOK调制,第二调制方式为FSK调制为例,以第一指示信息
#1和第二指示信息#1承载于WUR信号为例进行说明。
示例性地,S301可以作为S101a的一种具体示例。S301,每个WUR信号通过一个或多个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号进行传输。图6中的(a)所示,以网络设备向终端设备发送4个WUR信号为例。每个WUR信号对应的时域资源上承载以OOK方式调制的第一指示信息#1,每个WUR信号对应的频域资源上承载以FSK方式调制的第二指示信息#1。终端设备根据OOK调制方式解调出第一指示信息#1,通过FSK调制方式解调出第二指示信息#1。
例如,第一指示信息#1用位图方式表示。每个终端设备对应的随机函数值都在第一指示信息#1中占据至少两个比特位。示例性地,终端设备对应的随机函数值可以根据终端设备的UE ID确定。假设网络设备要唤醒UE#1,不唤醒UE#2。如图6中的(b)所示,UE#1对应的随机函数值在第一指示信息#1中的2个比特位,UE#2对应的随机函数值在第一指示信息#1中的2个比特位。UE#1对应的随机函数值在第一指示信息#1中的比特位全部被置为1。UE#2对应的随机函数值在第一指示信息#1中的比特位至少有一个未被置为1。可选地,UE#1和UE#2对应的随机函数值在第一指示信息#1中的比特位可能有重叠。
例如,第二指示信息#1如图6中的(c)所示。每个UE的UE ID在第二指示信息中对应x个比特,x≥1且x为整数。
需要说明的是,图6中的(b)仅为示例,并不限制第一指示信息#1只与两个UE对应,也不限制每个UE对应的随机函数值在第一指示信息#1中只对应2个比特位。图6中的(c)仅为示例,并不限制第二指示信息仅包括UE#1和UE#3的UE ID。
示例性地,S302可以作为S102a的一种具体示例。S302,以终端设备为UE#1为例,在第一指示信息#1和第二指示信息#1均指示UE#1的ID的情况下,终端设备的唤醒电路根据第一指示信息#1和第二指示信息#1确定要唤醒主电路。
上述方案,网络设备向终端设备发送的一个信号分别在时域和频域承载基于不同调制方式调制的指示信息,能够进一步提高资源的利用率。
可选地,如方法100中所述,在相同时间内传输所述第一指示信息#1的比特数小于传输所述第二指示信息#1的比特数。例如,在相同时间内传输所述第一指示信息#1的比特数与传输所述第二指示信息#1的比特数的比值为1:,N为移频键控调制方式的候选子载波的个数,N为正整数。可以理解的是,一个OFDM符号基于OOK调制方式携带第一指示信息#1中的1比特,以及,基于FSK调制方式携带第二指示信息#1中的比特。下面给出一个具体示例。
示例3,假设FSK方式调制的信号在频域有4个候选子载波,即N=4,此时,=2。从而,每个OFDM符号在频域携带的比特信息为2比特。假设第一指示信息#1为1110,大小为4比特。经过曼彻斯特编码后第一指示信息#1为10101001,总共需要8个OFDM符号承载。其中,有4个OFDM符号发送“1”,4个OFDM符号发送“0”。在每个发送“1”的OFDM符号上,可以使用FSK方式携带第二指示信息#1中的2比特。那么,该8个OFDM符号中用于发送“1”的4个OFDM符号总共能够携带第二指示信息#1中的8比特。因此在相同的时间内,例如这里的8个OFDM符号上,能够传输第一指示信息#1中的4比特,可以发送第二指示信息#1中的8比特。
或者,方法300的另一种实现方式中,终端设备仅支持OOK调制,则终端设备仅根据第一指示信息#1确定是否唤醒终端设备。具体可以参照上述与第一指示信息#1相关的描述。
下面结合图7至图9,给出方法100中的终端设备通过包络检波的方式接收到第一指示信息#1和第二指示信息#1的几种可能的实现方式,包括方法400至600。方法400至600对于第一调制方式和第二调制方式的说明可以参见方法100中对应的描述。
图7示出了本申请提供的信息传输的方法400的示意图。
S401,终端设备在至少两个频域位置检测能量。
示例性地,这里的频域位置可以是子载波。
S402可以有两种实现方式。例如下述S402a和S402b。
S402a,在至少两个频域位置中的全部频域位置检测到能量的情况下,确定接收到基于第一调制方式调制的第一指示信息#1。
示例性地,本申请中,在检测到的能量的值≥第一阈值的情况下,终端设备可以确定检测到能量。在这里进行统一说明,在方法500和方法600中不赘述。
在至少两个频域位置中的全部频域位置检测到能量,可以理解为,在至少两个频域位置中的全部频
域位置检测到的能量的值都大于或等于第一阈值。
S402b,在至少两个频域位置中的部分频域位置检测到能量的情况下,确定接收到基于第一调制方式调制的第一指示信息#1和基于第二调制方式调制的第二指示信息#1。
示例4-1,在第一频域位置检测到的能量的值为在至少两个频域位置中的检测到的能量的值中的最大值,终端设备根据第一频域位置确定第二指示信息#1。例如,结合示例3,在频域有4个候选子载波,包括子载波#1至子载波#4,假设终端设备在子载波#1检测的到能量的值最大,则终端设备可以确定在子载波#1接收到第二指示信息#1中的部分或全部比特。
可以理解的是,示例4-1中的第一频域配置和最大值的数量均可以是一个或多个。示例4-2,在m个第一频域位置检测到的能量的值为在至少两个频域位置中的检测到的能量的值中的最大的m个值,m≥1。终端设备根据m个第一频域位置确定第二指示信息#1。可以理解的是,将至少两个频域位置中的检测到的能量的值从大到小依次排列,前m个值即为在至少两个频域位置中的检测到的能量的值中的最大的m个值。例如,结合示例3,在频域有4个候选子载波,包括子载波#1至子载波#4。假设终端设备在4个候选子载波检测的到能量的值中,在子载波#1和子载波#4检测的到能量的值均大于在子载波#2和子载波#3检测的到能量的值,则终端设备可以确定在子载波#1和子载波#4接收到第二指示信息#1中的部分或全部比特。
上述方案,终端能够实现对基于不同调制方式调制的指示信息进行解调,以便于通过通信系统能够兼容采用不同调制方式调制或解调的信息。
图8示出了本申请提供的信息传输的方法500的示意图。
S501,终端设备在至少两个频域位置检测能量。
示例性地,这里的频域位置可以是子载波。
其中,至少两个频域位置包括第一频域位置和第二频域位置,第一频域位置与第二频域位置不同。
S502,终端设备根据在第一频域位置接收到的能量的值与在第二频域位置接收到的能量的值的第一比值确定是否接收到基于第一调制方式调制的第一指示信息或基于第二调制方式调制的第二指示信息。具体包括以下但不限于以下几种情况。
情况一:第一比值≥第二阈值或第一比值≤第三阈值的情况下,确定接收到第一指示信息和第二指示信息。可选地,第二阈值>1。可选地,第三阈值<1。
情况二:第二频域位置包括至少一个第三频域位置,第一比值包括至少一个第二比值。至少一个第二比值均≥第二阈值的情况下,终端设备根据第一频域位置确定第二指示信息#1。在至少一个第二比值中的一个或多个比值≤第三阈值的情况下,终端设备根据该一个或多个比值中的最小值对应的第三频域位置确定第二指示信息#1。
例如,结合示例3,在频域有4个候选子载波,包括子载波#1至子载波#4。终端设备在4个候选子载波检测能量。假设第二阈值为1.11,第三阈值为0.99。第一频域位置以子载波#1为例,至少一个第三频域位置以3个子载波为例,即子载波#2至子载波#4。至少一个第二比值以3个第二比值为例,即在子载波#1检测的能量的值与在子载波#2检测到的能量的值的比值、在子载波#1检测的能量的值与在子载波#3检测到的能量的值的比值、在子载波#1检测的能量的值与在子载波#4检测到的能量的值的比值。情况一,在该3个第二比值均大于或等于1.11的情况下,则终端设备可以确定在子载波#1接收到第二指示信息#1中的部分或全部比特。情况二,至少一个第二比值中的一个或多个比值以在子载波#1检测的能量的值与在子载波#3检测到的能量的值的比值为例。在子载波#1检测的能量的值与在子载波#3检测到的能量的值的比值≤0.99的情况下,则终端设备可以确定在子载波#3接收到第二指示信息#1中的部分或全部比特。
上述方案,终端能够实现对基于不同调制方式调制的指示信息进行解调,以便于通过通信系统能够兼容采用不同调制方式调制或解调的信息。
图9示出了本申请提供的信息传输的方法600的示意图。
S601,终端设备在一个时域位置和至少两个频域位置检测能量。
示例性地,这里的频域位置可以是子载波。
其中,至少两个频域位置包括第一频域位置和第二频域位置,第一频域位置与第二频域位置不同。
S602,在时域位置检测到能量的情况下,终端设备确定接收到基于第一调制方式调制的第一指示信息。
示例性地,这里的时域位置可以是一个或多个OFDM符号。
S603,在接收到第一指示信息的情况下,终端设备根据至少两个频域位置中检测到的能量的值中的最大值对应的频域位置确定基于第二调制方式调制的第二指示信息。
可以理解的是,如果在第一时域位置未接收到第一指示信息,则可以不执行S603。
示例性地,S603可以参见示例4-1和示例4-2对应的描述。
上述方案,终端能够实现对基于不同调制方式调制的指示信息进行解调,以便于通过通信系统能够兼容采用不同调制方式调制或解调的信息。终端设备分别在时域位置和频域位置检测能量,且在时域位置检测到能量的情况下,才对时域位置的检测结果进行判断。从而能够在终端设备在时域位置未检测到能量的情况下,避免对时域位置的检测结果进行判断,减少了终端设备的能耗,节省资源。
