图1是本申请实施例可应用的无线通信系统的示意图,图1示出的无线 通信系统包括终端11和网络侧设备12。其中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是,在本申请实施例并不限定终端11的具体类型。
网络侧设备12可以包括接入网设备或核心网设备,其中,接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、WLAN接入点或WiFi节点等,基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例进行介绍,并不限定基站的具体类型。核心网设备可以包含但不限于如下至少一项:核心网节点、核心网功能、移动管理实体(Mobility Management Entity,MME)、接入移动管理功能(Access and Mobility Management Function,AMF)、会话管理功能(Session Management Function,SMF)、用户平面功能(User Plane Function,UPF)、策略控制功能(Policy Control Function,PCF)、策略与计费规则功能单元(Policy and Charging Rules  Function,PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function,EASDF)、统一数据管理(Unified Data Management,UDM),统一数据仓储(Unified Data Repository,UDR)、归属用户服务器(Home Subscriber Server,HSS)、集中式网络配置(Centralized network configuration,CNC)、网络存储功能(Network Repository Function,NRF),网络开放功能(Network Exposure Function,NEF)、本地NEF(Local NEF,或L-NEF)、绑定支持功能(Binding Support Function,BSF)、应用功能(Application Function,AF)、位置管理功能(location manage function,LMF)、增强服务移动定位中心(Enhanced Serving Mobile Location Centre,E-SMLC)、网络数据分析功能(network data analytics function,NWDAF)等。需要说明的是,在本申请实施例中仅以NR系统中的核心网设备为例进行介绍,并不限定核心网设备的具体类型。
为了便于更加清晰地理解本申请各实施例,首先对一些相关的背景知识进行如下介绍。
一、单载波场景的同步
在单载波场景下,基站周期性地向终端发送该载波的同步信号块(Synchronization Signal Block,SSB)。
终端通过检测周期性发送的SSB确定下行同步,包括确定下行帧/子帧/时隙边缘。
二、载波聚合(Carrier Aggregation,CA)场景的同步
在CA场景中,主载波(Primary cell,Pcell)或主辅载波(Primary SCG Cell,PScell)的同步按照上述单载波场景的方法进行确定;
对于带内intra-band的辅小区(Secondary Cell,Scell),如果该Scell上有SSB配置,则终端通过检测配置的周期SSB确定该Scell上的下行同步;上行同步通过下行同步和时间提前量(Timing Advance,TA)指示确定;如果该Scell上没有SSB配置,则该Scell的同步通过其对应的Pcell或Pscell确定。
对于带间inter-band的Scell,必须有SSB配置,且该Scell的下行同步通过该SSB获得。目前的多载波部署场景,对于inter-band的载波必须都有SSB发送,这会导致基站的能耗较大。因此,在inter-band的部分或全部载波没有SSB发送的时候如何进行同步是需要解决的问题。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的同步参考小区确定方法进行详细地说明。
本申请实施例提供的同步参考小区确定方法中,终端根据小区集合中至少一个小区的配置信息,从小区集合中确定第一小区的同步参考小区,根据同步参考小区的同步信息确定第一小区的同步信息,终端利用第一小区的同步信息可以在网络侧设备没有发送第一小区的同步参考信号的情况下实现同步;相应地,通过解决终端同步问题,使网络侧设备在多小区部署的场景下实现仅向终端发送部分小区的同步参考信号,降低了网络侧设备的能耗,达到了网络节能的效果。
图2是本申请实施例提供的同步参考小区确定方法的流程示意图之一,如图2所示,该方法包括步骤201;其中:
步骤201、终端根据小区集合中至少一个小区的配置信息,从所述小区集合中确定第一小区的同步参考小区;所述配置信息用于辅助所述终端从所述小区集合中确定第一小区的同步参考小区;所述小区集合中包括所述第一小区。
需要说明的是,本申请实施例可应用于在多载波部署的情况下终端进行同步的场景中。所述终端包括但不限于上述所列举的终端11的类型,本申请对此并不限定。本申请实施例中小区可以包括载波,小区集合可以包括载波集合。同步参考信号例如可以是SSB、相位参考信号(Tracking Reference Signal,TRS)、CSI参考信号(CSI Reference Signal,CSI-RS)等。
由于在多载波部署的场景下,每个载波都有周期性的同步参考信号发送,会造成基站的能耗增大。因此,在多载波部署场景下,如果部分载波没有同步参考信号发送时,为了解决针对载波没有同步信号发送时终端同步的问题, 本申请实施例中,终端需要根据小区集合中至少一个小区的配置信息,从小区集合中确定第一小区的同步参考小区,其中,小区集合中至少一个小区的配置信息可以是基站向终端发送的,也可以是协议预定义的。
可选地,在终端从小区集合中确定第一小区的同步参考小区之后,终端需要根据同步参考小区的第一同步信息,确定第一小区的第二同步信息。也就是说,终端在确定出第一小区的同步参考小区之后,可以将同步参考小区的第一同步信息确定为第一小区的第二同步信息,从而使网络侧设备无需向终端发送第一小区的同步参考信号,便能实现终端针对第一小区的下行同步。

方式1、终端根据第一载波集合中的配置信息,在第一载波满足第一条件的情况下,直接确定第一载波为同步参考载波。
例如,第一条件为“第一载波有SSB发送或on demand SSB配置”;则对于cell0和cell2,其同步参考载波为Cell0和Cell2。

则对于cell5:cell0和cell2均有SSB配置发送或on demand SSB配置,并且abs(F5-F0)<=Fthresh;abs(F5-F2)<=Fthresh,即cell0和cell2满足第一准则,则第一载波cell5对应2个第二载波,即cell0、cell2。
步骤[2]、在M个第二载波中的第三载波(即上文提及的第三小区)满足第二准则(即上文提及的第三条件)的情况下,终端确定第三载波为第一载波的同步参考载波。
例如,第二准则为“优先级1:选择有实际SSB发送的;优先级2:选择频带号一样的,即intra-band的载波;优先级3:选择中心频率间隔最小的。”
对于cell5:cell0有实际SSB发送,则终端优先选择cell0为第一载波cell5的同步参考载波。
方式3、终端根据第一载波集合中的配置信息,在第一载波集合中第四载波(即上文提及的第四小区)满足第三准则(即上文提及的第四条件)的情况下,确定第四载波为同步参考载波。

针对其他第一载波,其确定同步参考载波的方式与上述步骤1-步骤2相同,在此不再赘述。
当cell2被确定为是cell3的同步参考载波之后,终端在cell2上发送唤醒信号触发cell2上的SSB发送。
