Description

一种用于无线通信的通信节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及非地面无线通信中的传输方案和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)(或5G)进行研究,在3GPP RAN#75次全会上通过了新空口技术(NR，New Radio)的WI(Work Item，工作项目)，开始对NR进行标准化工作。
为了能够适应多样的应用场景和满足不同的需求，在3GPP RAN#75次全会上还通过了NR下的非地面网络(NTN，Non-Terrestrial Networks)的研究项目，该研究项目在R15版本开始，然后在R16版本中启动WI对相关技术进行标准化。
发明内容
在NTN网络中，用户设备(UE，User Equipment)和卫星或者飞行器通过5G网络进行通信，卫星或飞行器在地面上的覆盖范围要远远大于传统基站的覆盖范围，同时由于角度和高度导致在同一个卫星或飞行器覆盖下的不同的用户设备到达服务卫星或飞行器的延时差异很大。根据3GPP TR38.811中的计算，这个延时差异可以达到十几毫秒以上(比如同步卫星下的最大延时差异在16毫秒左右)。另一方面，很多卫星或飞行器可以装配大量的天线进而支持达到地面不同地理区域的空间复用传输。在现有的NR系统中，同步广播信道的设计(即SS/PBCH Block)最多可以支持64个模拟波束，同时通过上行随机接入信道(PRACH，Physical Random Access Channel)的指示可以区分延时差异小于5毫秒的同步传输，从而保证上行传输定时(一般是TA，Timing Advance)的准确性。通过上面对比可以看出，现有的NR中的同步广播设计无法满足NTN网络中的大延时差异和更多的天线部署的需求。
针对NR NTN通信中的同步广播支持大延时差异和更多天线部署的问题，本申请提供了一种解决方案。需要说明的是，在不冲突的情况下，本申请的基站设备中的实施例和实施例中的特征可以应用到用户设备中，反之亦然。进一步的，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
