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，尤其涉及大的延时差的传输方案和装置。
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。在3GPP RAN#79次全会上决定开始研究NTN网络中的解决方案，然后在R16或R17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，由于卫星或飞行器到达用户设备的距离要远远大于地面基站到达用户设备的距离，因而导致卫星或飞行器与用户设备间通信传输时的较长的传输延时(Propagation Delay)。另外，当卫星被用作地面站的中继设备时，卫星与地面站之间的支线链路(Feeder Link)的延时会更加增大用户设备与基站间传输延时。另一方面，由于卫星和飞行器的覆盖范围和地面网络(Terrestrial Networks)相比要大得多，同时由于地面设备到卫星或飞行器的倾角不同，导致在NTN中的延时之间的差别非常大。在现有的LTE(Long Term Evolution，长期演进)或5G NR系统中，最大延时差只有几微秒或者几十微秒，但是在NTN中最大延时差可以达到几毫秒甚至几十毫秒。由于现有的LTE或NR中的随机接入都是为传统地面通信设计的，无法直接应用到NTN网络中，因而需要新的设计来支持大延时差网络，特别是NTN通信。
针对大延时差网络，特别是NTN通信中的随机接入中的问题，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。
