为便于理解本申请实施例的技术方案,对本申请相关的基于唤醒接收机的终端节能进行说明。
唤醒接收机(WUR)具有极低成本、极低复杂度和极低功耗的特点,其可以通过基于包络检测的方式接收唤醒信号(WUS)。因此,唤醒接收机(WUR)接收的唤醒信号(WUS)与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(WUS)可以是通过对载波信号进行幅移键控(Amplitude Shift Keying,ASK)调制得到的包络信号。包络信号的解调也主要基于无线射频信号提供的能量驱动低功耗电路来完成,因此唤醒接收机(WUR)可以是无源的。唤醒接收机也可以通过终端进行供电,无论哪种供电方式,唤醒接收机相比终端的主收发机(main radio)极大的降低了功耗。唤醒接收机可以和终端结合在一起,作为终端的主收发机(main radio)的一个附加模块,也可以单独作为一个终端的唤醒功能模块。
具体的,唤醒接收机接收唤醒信号,如果需要终端打开主收发机(main radio),可以指示终端开启主收发机(main radio),例如,通过反向散射信号指示终端开启主收发机(main radio)。否则,终端的主收发机(main radio)可以处于休眠或关闭状态。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。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。本申请实施例包括以下内容中的至少部分内容。
图2是根据本申请实施例的无线通信的方法200的示意性流程图,如图2所示,该无线通信的方法200可以包括如下内容中的至少部分内容:
S210,网络设备发送至少一个信息;其中,该至少一个信息用于指示以下至少之一:该网络设备是否支持WUS区域,以及激活或去激活基于WUS的节能模式;
S220,终端设备接收该至少一个信息。
在本申请实施例中,该终端设备可以基于该至少一个信息确定该网络设备是否支持WUS区域,和/或,激活或去激活基于WUS的节能模式。
在本申请实施例中,终端设备的唤醒接收机(WUR)对应的唤醒信号(WUS)的覆盖范围与终端设备的主收发机(main radio)对应的无线信号的覆盖范围不同,其中,终端设备的唤醒接收机(WUR)对应的唤醒信号(WUS)的覆盖范围可以称之为WUS区域(WUS Zone,WZ)。具体例如,双覆盖(Dual Coverage)场景下,WUS区域可以如图3所示。
需要注意的是,本申请实施例也可以适用于如下情况:终端设备的唤醒接收机(WUR)对应的唤醒信号(WUS)的覆盖范围与终端设备的主收发机(main radio)对应的无线信号的覆盖范围只有逻辑上的分别,但在实际地理区域覆盖上一致。
应理解,唤醒接收机(WUR)对应的唤醒信号(WUS)的覆盖范围也可以称之为其他与WUS区域类似的名称,本申请实施例对此并不限定。
需要说明的是,唤醒接收机的能耗较低,如小于一个预设值,唤醒接收机可以通过其所属的终端设备获取能量,也可以类似于零功耗设备,通过能量采集获得能量以用于通信、信息采集及处理。具体例如,唤醒接收机可以通过无线射频信号,太阳能,压力或温度等无线供能方式获得能量。
在本申请实施例中,唤醒接收机也可以称之为低功耗接收机或零功耗接收机,或类似的名称,本申请对此并不限定。
在一些实施例中,唤醒信号也可以是唤醒接收机的供能信号。
在一些实施例中,基于WUS的节能模式主要部署在密集或室内场景,并且不需要每个网络设备(如gNB)均支持WUS区域。即使网络设备(如gNB)支持WUS区域和基于WUS的省电模式,具有唤醒接收机(WUR)和主收发机(main radio)的终端设备可以激活唤醒接收机(WUR)以降低功耗。可选地,网络设备(如gNB)也可能并不是一直激活基于WUS的节能模式。例如,在某些情况下,WUS区域中的终端设备可以禁用省电模式以实现最佳性能。
在一些实施例中,该至少一个信息包括第一信息,其中,该第一信息用于指示激活基于WUS的节能模式,且该网络设备默认支持WUS区域。

具体又例如,该第一信息占用一个比特位,其中,该第一信息可以复用承载该第一信息的信令中的信息域中的一个比特位。
在一些实施例中,该第一信息通过系统广播承载。也即,处于WUS区域内的所有终端均可以激活基于WUS的节能模式,并执行相应的节能操作。
在一些实施例中,该第一信息通过主信息块(Master Information Block,MIB)或系统信息块1(System Information Block 1,SIB1)中的广播同步信号承载。可选地,该第一信息也可以通过MIB或SIB1中的其他信号或信息域承载,本申请实施例对此并不限定。
可选地,该第一信息也可以通过SIB x承载,x的取值可以为系统消息中除1之外的其他取值。
在一些实施例中,该第一信息为该终端设备在初始同步的过程中接收的。也即,当终端设备进行初始同步时,该终端设备可以获取该第一信息并获知当前网络设备(如gNB)是否支持基于WUS的节能模式。

在一些实施例中,该至少一个信息包括第二信息和第三信息,其中,该第二信息用于指示该网络设备支持WUS区域,该第三信息用于指示激活或去激活基于WUS的节能模式。也即,在网络设备支持WUS区域的情况下,网络设备可以进一步地指示激活或去激活基于WUS的节能模式。在网络设备指示激活基于WUS的节能模式的情况下,终端设备激活基于WUS的节能模式,并执行相应的节能操作。
具体例如,该第二信息占用一个比特,其中,取值0用于指示网络设备支持WUS区域,或者,取值1用于指示网络设备支持WUS区域。可选地,该第二信息占用的比特可以是承载该第二信息的信令中的预留比特,或者,该第二信息可以复用承载该第二信息的信令中的信息域中的一个比特。
具体又例如,该第二信息占用一个比特位,其中,该第二信息可以复用承载该第二信息的信令中的信息域中的一个比特位。
具体例如,该第三信息占用一个比特;其中,取值0用于指示激活基于WUS的节能模式,取值1用于指示去激活基于WUS的节能模式;或者,取值1用于指示激活基于WUS的节能模式,取值0用于指示去激活基于WUS的节能模式。可选地,该第三信息占用的比特可以是承载该第三信息的信令中的预留比特,或者,该第三信息可以复用承载该第三信息的信令中的信息域中的一个比特。
在一些实施例中,该第二信息和该第三信息均通过系统广播承载。也即,在网络设备指示激活基于WUS的节能模式的情况下,处于WUS区域内的所有终端均可以激活基于WUS的节能模式,并执行相应的节能操作。
在一些实施例中,该第二信息和该第三信息均通过MIB或SIB1中的广播同步信号承载。可选地,该第二信息和该第三信息也可以通过MIB或SIB1中的其他信号或信息域承载,本申请实施例对此并不限定。
在一些实施例中,该第二信息和该第三信息均可以通过SIB x承载,x的取值可以为系统消息中除1之外的其他取值。
在一些实施例中,该第二信息和该第三信息均为该终端设备在初始同步的过程中接收的。也即,当终端设备进行初始同步时,该终端设备可以获取获知当前网络设备(如gNB)是否支持WUS区域,以及获知是否激活基于WUS的节能模式。
在一些实施例中,该第二信息通过系统广播承载;和/或,
该第三信息通过以下之一承载:RRC信令,MAC CE,DCI。
也即,针对广播覆盖范围内的所有的UE可以通过广播指示网络设备支持WUS区域,以及针对每个UE单独地指示激活或去激活基于WUS的节能模式,可以增加网络设备指示的灵活性。
在一些实施例中,该第二信息通过MIB或SIB1中的广播同步信号承载。可选地,该第二信息也可以通过MIB或SIB1中的其他信号或信息域承载,本申请实施例对此并不限定。
在一些实施例中,该第二信息为该终端设备在初始同步的过程中接收的。
在一些实施例中,在接收该至少一个信息之前,该终端设备发送第一请求信息,其中,该第一请求信息用于请求激活基于WUS的节能模式。例如,在终端设备处于低电量的情况下,该终端设备发送该第一请求信息。
具体例如,终端设备向网络设备发送第一请求信息,网络设备在接收到该第一请求信息之后,可 以通过RRC信令或MAC CE或DCI指示激活基于WUS的节能模式。
在一些实施例中,该终端设备发送第四信息,其中,该第四信息用于指示该终端设备处于基于WUS的节能模式。也即,终端设备已经激活了基于WUS的节能模式。
可选地,该第四信息通过测量报告承载。可选地,该第四信息也可以通过以下之一承载:RRC信令,MAC CE,上行控制信息(Uplink Control Information,UCI)。
在一些实施例中,终端设备可以上报第一能力信息,其中,该第一能力信息用于指示该终端设备是否支持WUS。可选地,该第一能力信息可以通过UCI或者终端设备能力报告承载。
在一些实施例中,在至少一个信息指示激活基于WUS的节能模式的情况下,在WUS区域内,终端设备的唤醒接收机(WUR)与网络设备之间的同步基于终端设备的主收发机(main radio)实现。
具体的,当终端设备在WUS区域中时,其WUR和主收发机(main radio)都需要与网络设备(如gNB)同步。由于WUR和主收发机可能具有不同的同步精度要求,实现主收发机与网络设备之间的同步并不一定意味着也实现了WUR与网络设备之间的同步。WUR与网络设备之间的同步可以依赖于主收发机与网络设备之间的同步,在这种情况下,不需要设计和配置专用于WUR的同步信号,并且可以提高资源效率。
在一些实施例中,WUR与网络设备之间的同步通过主收发机针对WUR执行的校准实现。
在一些实施例中,主收发机针对WUR执行的校准,包括:
主收发机在被WUR定期唤醒之后执行的校准,或者,主收发机在失步之后被WUR唤醒且与网络设备之间同步之后针对WUR的校准。
具体例如,在主收发机针对WUR执行的校准为主收发机在被WUR定期唤醒之后执行的校准的情况下,WUR唤醒主收发机的周期由协议约定,或者,WUR唤醒主收发机的周期由网络设备配置。此种情况下,主收发机与网络设备之间是同步的。
具体例如,在主收发机针对WUR执行的校准为主收发机在失步之后被WUR唤醒且与网络设备之间同步之后针对WUR的校准的情况下,在校准WUR之后,主收发机恢复到休眠状态,或者,主收发机恢复到断电状态。也即,在主收发机失步之后,WUR唤醒主收发机,主收发机在被唤醒后搜索SSB,并在实现同步后帮助校准WUR,之后,主收发机会回到深度睡眠或断电状态。
在一些实施例中,在该至少一个信息指示激活基于WUS的节能模式的情况下,在WUS区域内,该终端设备的WUR与该网络设备之间的同步基于该WUR的同步信号实现。也即,可以为WUR配置专用同步信号。
在一些实施例中,该WUR的同步信号对应的时频资源位于频带的固定位置。可选地,该WUR的同步信号对应的时频资源位于整个频带的中心。也即,该WUR的同步信号对应的时频资源的位置和大小可以是固定的。
在一些实施例中,该WUR的同步信号对应的时频资源由协议约定,或者,该WUR的同步信号对应的时频资源由网络设备半静态配置,或者,该WUR的同步信号对应的时频资源由网络设备动态配置。
在一些实施例中,该WUR的同步信号对应的时频资源基于该终端设备的主收发机的同步信号对应的时频资源确定。也即,WUR的同步信号对应的时频资源与主收发机的同步信号对应的时频资源之间存在一定的关联关系。
例如,主收发机的同步信号可以是同步信号块(Synchronization Signal Block,SSB)。
在一些实施例中,该WUR的同步信号对应的时频资源与该主收发机的同步信号对应的时频资源之间存在固定的偏移。
在一些实施例中,该WUR的同步信号对应的时域资源与该主收发机的同步信号对应的时域资源之间存在第一偏移,和/或,该WUR的同步信号对应的频域资源与该主收发机的同步信号对应的频域资源之间存在第二偏移。可选地,该WUR的同步信号对应的时域资源的大小可以是固定的。
可选地,该第一偏移的取值可以是正值,也可以是负值,本申请实施例对此并不限定。
可选地,该第二偏移的取值可以是正值,也可以是负值,本申请实施例对此并不限定。
例如,第一偏移为4个正交频分复用(Orthogonal frequency-division multiplexing,OFDM)符号,第二偏移为0。
在一些实施例中,该第一偏移可以是WUR的同步信号对应的时域资源的起始位置与主收发机的同步信号对应的时域资源的起始位置之间的偏移;或者,该第一偏移可以是WUR的同步信号对应的时域资源的结束位置与主收发机的同步信号对应的时域资源的结束位置之间的偏移;或者,该第一偏移可以是WUR的同步信号对应的时域资源的起始位置与主收发机的同步信号对应的时域资源的结束 位置之间的偏移;或者,该第一偏移可以是WUR的同步信号对应的时域资源中间的某一特定位置与主收发机的同步信号对应的时域资源中间的某一特定位置之间的偏移。
在一些实施例中,该第二偏移可以是WUR的同步信号对应的频域资源的起始位置与主收发机的同步信号对应的频域资源的起始位置之间的偏移;或者,该第二偏移可以是WUR的同步信号对应的频域资源的结束位置与主收发机的同步信号对应的频域资源的结束位置之间的偏移;或者,该第二偏移可以是WUR的同步信号对应的频域资源的起始位置与主收发机的同步信号对应的频域资源的结束位置之间的偏移;或者,该第二偏移可以是WUR的同步信号对应的频域资源中间的某一特定位置与主收发机的同步信号对应的频域资源中间的某一特定位置之间的偏移。
具体例如,WUR的同步信号对应的时频资源和主收发机的同步信号对应的时频资源可以如图4所示,该第一偏移可以是WUR的同步信号对应的时域资源的起始位置与主收发机的同步信号对应的时域资源的结束位置之间的偏移,该第二偏移可以是WUR的同步信号对应的频域资源的起始位置与主收发机的同步信号对应的频域资源的结束位置之间的偏移。
在一些实施例中,WUR的同步信号与主收发机的同步信号之间准共址(Quasi-co-located,QCL)。可选地,该WUR的同步信号和该主收发机的同步信号对应的QCL为QCL类型D(QCL type D)。
在一些实施例中,终端设备可以假定该WUR的同步信号对应的空间滤波器与该主收发机的同步信号对应的空间滤波器具有相同的模式。
需要说明的是,空间滤波器(spatial filter)也可以称为波束(beam)、波束对(beam pair)、空间关系(Spatial relation)、空间配置(spatial setting)、空域滤波器(spatial domain filter),或者,参考信号。
在一些实施例中,WUR的同步信号和主收发机的同步信号的波束可以配置为具有相同的模式,使得一旦主收发机被唤醒,主收发机就具有关于要同步的同步信号的波束的一些先验信息。在这方面,WUR的同步信号可以被配置为准共址的(QCLed),主收发机的同步信号至少具有QCL类型D。或者,终端设备可以默认WUR的同步信号和主收发机的同步信号的波束采用相同的模式,或者默认可是使用相同的接收波束接收WUR的同步信号和主收发机的同步信号。此外,相同的波束标识(ID)可以显式或隐式地配置到WUR的同步信号和主收发机的同步信号的波束。
在一些实施例中,该WUR的同步信号的周期为该主收发机的同步信号的周期的n倍,其中,n为正整数,且n≥1。可选地,n的取值从系统信息中获取。
具体的,WUR的同步信号可以具有比主收发机的同步信号更长的持续时间,所以WUR的同步信号的周期可以是主收发机的同步信号的n倍,并且可以在系统信息中配置n。
在一些实施例中,在至少一个信息指示激活基于WUS的节能模式,且该终端设备的主收发机处于唤醒状态的情况下,该WUS区域内针对服务小区和/或邻小区的测量由该主收发机执行。
在一些实施例中,终端设备是否处于WUS区域内由终端设备与网络设备之间的距离确定。
在一些实施例中,在该终端设备与该网络设备之间的距离小于或等于第一阈值的情况下,该终端设备处于该WUS区域内;和/或,在该终端设备与该网络设备之间的距离大于第一阈值的情况下,该终端设备处于该WUS区域外。
在一些实施例中,在该终端设备与该网络设备之间的距离小于第一阈值的情况下,该终端设备处于该WUS区域内;和/或,在该终端设备与该网络设备之间的距离大于或等于第一阈值的情况下,该终端设备处于该WUS区域外。
在一些实施例中,该第一阈值可以由协议约定,或者,该第一阈值可以由网络设备配置或指示。
在一些实施例中,该终端设备是否处于该WUS区域内基于该终端设备的WUR的灵敏度和该主收发机测量SSB的得到的参考信号接收功率(Reference Signal Received Power,RSRP)确定。
具体例如,基于终端设备的WUR的灵敏度可以确定阈值x。其中,在主收发机测量SSB的得到的RSRP大于或等于阈值x的情况下,终端设备处于WUS区域内;和/或,在主收发机测量SSB的得到的RSRP小于阈值x的情况下,终端设备处于WUS区域外。或者,在主收发机测量SSB的得到的RSRP大于阈值x的情况下,终端设备处于WUS区域内;和/或,在主收发机测量SSB的得到的RSRP小于或等于阈值x的情况下,终端设备处于WUS区域外。
在一些实施例中,一旦终端设备处于WUS区域内,如果网络设备(如gNB)在系统信息中指示激活基于WUS的节能模式,则终端设备可以在基于WUS的节能模式下操作而无需请求网络设备(如gNB)的许可。可选地,终端设备可以通过测量报告或单独通知网络设备(如gNB)其正在基于WUS的节能模式下操作。可选地,终端设备可以向网络设备(如gNB)发送基于WUS的节能模式激活请求,并且网络设备(如gNB)可以通过RRC/MAC/DCI信令激活基于WUS的节能模式。
在一些实施例中,在该至少一个信息指示激活基于WUS的节能模式,且该终端设备的主收发机处于休眠状态的情况下,该WUS区域内针对服务小区的测量由该终端设备的WUR执行;和/或,第一区域内针对服务小区和/或邻小区的测量由该主收发机执行;和/或,第二区域内针对服务小区的测量由该终端设备的WUR执行,和/或,该第二区域内针对服务小区的测量由该主收发机执行;
其中,该主收发机由该WUR唤醒,该第一区域和该第二区域均处于该WUS区域外,且该第二区域处于该第一区域与该WUS区域之间。
需要说明的是,如果主收发机处于休眠状态,WUR可以进行测量,然而,WUR测量的模数转换器(Analog-to-Digital Converter,ADC)的粒度非常粗糙,测量结果不可靠,因此无法准确识别WUS区域内与WUS区域外,基于此,本实施例中设计了第一区域和第二区域。也即,基于WUR的测量无法准确确定第二区域处于WUS区域内还是WUS区域外,第二区域可以是一个比较模糊的区域(ambiguity zone)。
在一些实施例中,在该第二区域内,该主收发机由该WUR唤醒,包括;
该主收发机由该WUR周期性地唤醒,或者,该主收发机由该WUR按需唤醒。
可选地,WUR周期性地唤醒主收发机的周期信息由协议约定,或者,WUR周期性地唤醒主收发机的周期信息由网络设备配置或指示。
在一些实施例中,该终端设备所处的区域由该终端设备与该网络设备之间的距离确定。
在一些实施例中,在该终端设备与该网络设备之间的距离小于第二阈值的情况下,该终端设备处于该WUS区域内;和/或,在该终端设备与该网络设备之间的距离大于或等于第二阈值且小于或等于第三阈值的情况下,该终端设备处于该第二区域;和/或,在该终端设备与该网络设备之间的距离大于第三阈值的情况下,该终端设备处于该第一区域。
在一些实施例中,在该终端设备与该网络设备之间的距离小于或等于第二阈值的情况下,该终端设备处于该WUS区域内;和/或,在该终端设备与该网络设备之间的距离大于第二阈值且小于第三阈值的情况下,该终端设备处于该第二区域;和/或,在该终端设备与该网络设备之间的距离大于或等于第三阈值的情况下,该终端设备处于该第一区域。
在一些实施例中,该终端设备所处的区域基于该终端设备的WUR测量同步信号得到的信号强度确定。
在一些实施例中,在该终端设备的WUR测量的信号强度大于第四阈值的情况下,该终端设备处于该WUS区域内;和/或,在该终端设备的WUR测量的信号强度小于或等于第四阈值且大于或等于第五阈值的情况下,该终端设备处于该第二区域;和/或,在该终端设备的WUR测量的信号强度小于第五阈值的情况下,该终端设备处于该第一区域。
在一些实施例中,在该终端设备的WUR测量的信号强度大于或等于第四阈值的情况下,该终端设备处于该WUS区域内;和/或,在该终端设备的WUR测量的信号强度小于第四阈值且大于第五阈值的情况下,该终端设备处于该第二区域;和/或,在该终端设备的WUR测量的信号强度小于或等于第五阈值的情况下,该终端设备处于该第一区域。
具体例如,第四阈值和第五阈值可以如图5所示。具体可以通过WUR测量的信号强度与第四阈值和第五阈值明确第一区域、第二区域和WUS区域。
因此,在本申请实施例中,网络设备可以指示其是否支持WUS区域,以及指示激活或去激活基于WUS的节能模式,也即,网络设备可以灵活控制基于WUS的节能模式,从而可以保证双覆盖(Dual Coverage)场景下的WUR性能,提升了基于WUR的终端节能效果。进一步地,本申请实施例明确了WUR与网络设备同步的方案和WUS区域测量的方案,从而可以提升双覆盖(Dual Coverage)场景下的WUR性能。
