Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信***中的传输方法和装置，尤其涉及无线通信中非地面网络(NTN，Non-Terrestrial Networks)中的传输方法和装置。
背景技术
未来无线通信***的应用场景越来越多元化，不同的应用场景对***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进行通信传输时存在较长的传输延迟(Propagation Delay)。除此之外，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)的延迟会更加增大用户设备与基站间传输延迟。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，造成在NTN中的同一卫星服务下，不同终端因为处于卫星覆盖的中心和边缘的缘故导致TA(Timing Advance，定时提前)的差别很大。在现有的LTE(Long Term Evolution，长期演进)或5G NR***中，一个终端会维系多个定时器以应用于RRC(Radio Resource Control，无线资源控制)重建(Re-establishment)、小区重选(Cell-reselection)、进入RRC_IDLE态等步骤或操作的判断，然后上述定时器的起始值的配置往往基于地面网络的特点，对NTN网络中传输延迟以及处理延迟大等特点的考虑较少。
针对大延迟网络，特别是NTN通信场景中大延迟的问题，本申请提供了一种解决方案。需要说明的是，上述问题描述中，NTN场景仅作为本申请所提供方案的一个应用场景的举例；本申请也同样适用于例如地面网络的场景，取得类似NTN场景中的技术效果。类似的，本申请也同样适用于例如存在UAV(Unmanned Aerial Vehicle，无人驾驶空中飞行器)，或物联网设备的网络的场景，以取得类似NTN场景中的技术效果。此外，不同场景(包括但不限于NTN场景和地面网络场景)采用统一解决方案还有助于降低硬件复杂度和成本。
