一、网络场景
通信系统场景包括地面通信网络(Terrestrial Network,TN)和非地面通信网络(Non Terrestrial Network,NTN)。其中,NTN一般采用卫星通信的方式向地面用户提供通信服务。NTN系统目前包括新无线NTN(NR-NTN)和物联网NTN(Internet of Things NTN,IoT-NTN)系统,后续还可能包括其他的NTN系统。
图1A为本申请实施例提供的一种通信系统的架构示意图。如图1A所示,通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端设备、终端设备)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。
图1A示例性地示出了一个网络设备和两个终端设备,在本申请一些实施例中,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
图1B为本申请实施例提供的另一种通信系统的架构示意图。参见图1B,包括终端设备1101和卫星1102,终端设备1101和卫星1102之间可以进行无线通信。终端设备1101和卫星1102之间所形成的网络还可以称为NTN。在图1B所示的通信系统的架构中,卫星1102可以具有基站的功能,终端设备1101和卫星1102之间可以直接通信。在系统架构下,可以将卫星1102称为网络设备。在本申请一些实施例中,通信系统中可以包括多个网络设备1102,并且每个网络设备1102的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。

端设备,本申请实施例对此不做限定。
二、网络节能
网络节能(Network energy saving)对环境可持续性、减少对环境的影响(减少温室气体排放)、以及节省运营成本有重大意义。能源消耗已经成为运营商的运营成本(operational expenditure,OPEX)的一个关键部分。大多数的能源消耗来自于无线接入网络。
三、NR系统中的SSB传输和多载波场景
NR系统中,终端设备的初始接入过程可以通过检测同步栅格(Sync Raster)上的同步信号块(Synchronization Signal/PBCH Block,SSB或SS/PBCH block)来完成。终端设备在初始接入过程中,通过预定义的SSB可能的时频位置,尝试搜索SSB,通过检测到的SSB获得时间和频率同步、无线帧定时以及小区标识(Identity,ID)。
在终端设备接入网络后,网络设备可以根据终端设备的能力,为终端设备配置多个服务小区作为辅小区,以提高终端设备数据传输的峰值速率。终端设备的多个服务小区可以以载波聚合(Carrier Aggregation,CA)或双连接(Dual Connectivity,DC)的方式为终端设备服务。网络设备可以通过媒体接入控制控制元素(Media Access Control-Control Element,MAC CE)命令激活或去激活为终端设备配置的辅小区。在网络设备激活终端设备的辅小区时,还可以为终端设备指示该辅小区的跟踪参考信号(Tracking Reference Signal,TRS)信息,以使终端设备可以基于该辅小区上的TRS快速进行小区同步。终端设备的多个服务小区可以属于相同的定时提前组(Timing Advance Group,TAG),也可以属于不同的TAG。对于属于同一个TAG的服务小区关联的上行小区,可以使用相同的定时参考小区和相同的定时提前值。
为了实现网络节能,在终端设备的辅小区上,网络设备可以不传输SSB,终端设备也不接收SSB。然而,在一些情况下,例如,在终端设备的一个TAG包括的一个或多个服务小区中,需要有一个定时参考小区,以使终端设备可以根据该定时参考小区来获取该TAG关联的上行小区的定时提前值。如果该定时参考小区为辅小区,终端设备需要接收该辅小区上的SSB来获取定时同步。又例如,在网络设备通过MAC CE命令激活为终端设备配置的辅小区时,终端设备需要接收该辅小区上的SSB来获取定时同步。又例如,终端设备需要基于辅小区上的SSB来进行层1或层3的测量。然而,如何使终端设备在辅小区上接收SSB、或者如何使网络设备获知终端设备具有在辅小区上接收SSB的需求,从而使网络设备在对应的辅小区上发送SSB,目前并不清楚。
图2是根据本申请一实施例的无线通信方法200的示意性流程图。该方法可选地可以应用于图1所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S210、终端设备在第一小区上接收网络设备发送的第一下行信道或信号。
在一些实施例中,第一小区为终端设备的辅小区或主小区。作为示例,第一小区为终端设备的辅小区。
在一些实施例中,第一下行信道或信号的类型包括以下中的一种或多种:SSB、系统消息块1(System Information Block1,SIB1)、信道状态信息-参考信号(Channel State Information-Reference Signal,CSI-RS)、跟踪参考信号(TRS)、定位参考信号(Positioning Reference Signal,PRS)。其中,SSB可以包括SSB突发(SSB burst)或SSB突发中的一个或多个SSB。CSI-RS可以包括以下中的一种或多种:用于CSI获取的CSI-RS、用于波束管理(Beam Management,BM)的CSI-RS。作为示例,第一下行信道或信号为SSB。
通过本申请实施例提出的无线通信方法,终端设备可以在该终端设备的辅小区上接收SSB。
在本申请实施例中,第一小区上可以不传输第一下行信道或信号,例如终端设备的辅小区上可以不传输SSB,以实现网络节能。为了使网络设备获知终端设备需要在第一小区上接收第一下行信道或信号,终端设备可以向网络设备请求在第一小区上发送第一下行信道或信号,或者网络设备也可以主动在第一小区上发送第一下行信道或信号并通知终端设备。例如,为了使网络设备获知终端设备需要在辅小区上接收SSB或其他参考信号例如CSI-RS或PRS或TRS等的需求,终端设备可以向网络设备请求在辅小区上传输SSB,或者网络设备也可以主动在辅小区上传输SSB并通知终端设备。因此,本申请中提出了如下几种方案。
方案1:网络设备向终端设备发送第二下行信道或信号,该第二下行信道或信号用于指示网络设备在第一小区上是否发送第一下行信道或信号(例如SSB)。终端设备接收第二下行信道或信号。在第二下行信道或信号指示网络设备在第一小区上发送第一下行信道或信号的情况下,网络设备在第一小区上发送第一下行信道或信号,终端设备在第一小区上接收第一下行信道或信号。利用本方案,网络设备可
以指示终端设备在辅小区上接收SSB,终端设备可以在辅小区上接收SSB。
方案2:终端设备向网络设备发送第一上行信道或信号,该第一上行信道或信号用于请求网络设备在第一小区上发送第一下行信道或信号(例如SSB)。网络设备在收到该第一上行信道或信号后,在第一小区上发送第一下行信道或信号。终端设备在发送第一上行信道或信号后,在第一小区上接收第一下行信道或信号。利用本方案,可以使网络设备获知终端设备具有在辅小区上接收SSB的需求,从而使网络设备在对应的辅小区上发送SSB。
方案3:终端设备向网络设备发送第一上行信道或信号,该第一上行信道或信号用于请求网络设备在第一小区上发送第一下行信道或信号(例如SSB)。网络设备在收到该第一上行信道或信号后,向终端设备发送第二下行信道或信号,该第二下行信道或信号用于指示网络设备在第一小区上是否发送第一下行信道或信号。第二下行信道或信号可以作为第一上行信道或信号的响应,也可以作为网络设备向终端设备(例如发送第一上行信道或信号的终端设备和/或未发送第一上行信道或信号的终端设备)通知在第一小区上是否发送第一下行信道或信号的指示。终端设备在发送第一上行信道或信号后,接收第二下行信道或信号。在第二下行信道或信号指示网络设备在第一小区上发送第一下行信道或信号的情况下,网络设备在第一小区上发送第一下行信道或信号,终端设备在第一小区上接收第一下行信道或信号。利用本方案,可以使网络设备获知终端设备具有在辅小区上接收SSB的需求,从而使网络设备在对应的辅小区上发送SSB;并且网络设备可以指示终端设备在辅小区上接收SSB。
在一些示例中,第一下行信道或信号和第二下行信道或信号有接收的先后顺序要求,例如,终端设备先检测或接收第二下行信道或信号,然后根据第二下行信道或信号的检测或接收结果确定接收或是否接收第二下行信道或信号。
