Description

一种被用于无线通信的方法和设备 技术领域
本申请涉及无线通信系统中的传输方法和装置,尤其涉及大时延的传输方法和装置。
背景技术
面对越来越高的通信需求,3GPP(3rd GenerationPartner Project,第三代合作伙伴项目)开始研究非地面网络通信(Non-Terrestrial Network,NTN),3GPPRAN#80次会议决定开展“NR(NewRadio,新空口)支持非地面网络的解决方案”研究项目,它是对前期“NR支持非地面网络”研究项目的延续(RP-171450),其中发送定时是一个重要的研究目标。
定时提前量(TimingAdvance,TA)被用户设备(UserEquipment,UE)用于提前(Advance)/延迟(Delay)给基站(eNodeB,eNB)发送消息,从而补偿传播时延(Propagation Delay)的影响,保证不同终端设备发送的消息在基站的接收窗内是对齐的。
发明内容
当前3GPP协议中,在随机接入(RandomAccess,RA)阶段,用户设备给基站发送随机接入前导码(Preamble)序列,基站利用用户设备发送的前导码确定所述用户设备的定时提前量(TimingAdvance),并将定时提前命令(TimingAdvanceCommand,TAC)作为随机接入响应(RandomAccess Response,RAR)的一部分,由基站发送给用户设备,其中定时提前命令包含索引值(Index)T A。定时提前命令中的索引值乘以时间颗粒度,得到用户设备的发送时间提前量。在LTE(LongTermEvolution,长期演进)系统中,定时提前命令包括11信息比特,时间颗粒度是16与基本时间单位T s的乘积,其中,T s=1/(15000×2018)秒;在5G(5th Generation)NR系统中,定时提前命令包括12信息比特,时间颗粒度是16×64/2μ个基本时间单位T c,其中,μ的取值为{0,1,2,3,4}中的一个,分别对应子载波间隔(SubcarrierSpace,SCS)等于{15kHz,30kHz,60kHz,120kHz,240kHz}中的之一的场景,T c=1/(Δf max·N f)秒。随机接入后,用户设备和基站建立连接,在RRC_CONNECTED状态,基站需要负责维护用户设备的定时提前量,并通过TAC(TimingAdvanceCommand,定时提前命令)MAC(MediumAccessControl,媒体接入控制)CE(ControlElement,控制单元)将定时提前按量的调整值发送给用户设备,TACMACCE中包含定时提前命令。在LTE系统和NR系统中,TACMACCE中定时提前命令包括6信息比特。
由于当前3GPP协议中规定的定时提前是针对地面通信网络(Terrestrial Network,TN)设计的,定时提前命令的时间颗粒度支持的最大传输距离约为几十公里。非地面通信中,卫星与用户设备之间的传输距离和时延远远大于地面通信网络,当前的定时提前命令的相关参数不能同时满足非地面通信需求,需要针对大时延场景下的定时提前量对定时提前命令重新进行设计。
针对上述问题,本申请提供了一种解决方案。针对上述问题描述中,采用NTN场景仅作为本申请应用的一个例子;本申请也同样适用于例如地面传输的场景,取得类似NTN场景中的技术效果。此外,不同场景采用统一解决方案还有助于降低硬件复杂度和成本。
