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，尤其涉及大延时的传输方案和装置。
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。在现有的LTE(Long Term Evolution，长期演进)或5G NR系统中，为了保证上行传输的同步进而避免用户间干扰和降低调度复杂性，网络设备会根据传输延时来配置用户设备上行传输的定时提前量(TA，Timing Advance)。由于现有的TA配置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网络，特别是NTN通信。
针对大延时网络，特别是NTN通信中的上行定时调整的问题，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。

作为一个实施例，本申请和现有地面网络中的TA调整的方法相比，具有如下主要技术优势：
-在大延时网络中(比如NTN)，由于大的传输时延的差距需要大量的TA信令开销来保证上行传输的同步，本申请中的方法通过将TA调整/更新分成整数部分和小数部分，在保证上行传输的正交性的同时，去除了上行传输到达接收机对齐的限制，使得基站能够根据实现需要对上行传输定时进行整数符号的调整，提高了调度灵活性。
-本申请中的方法使得在大延时网络中最大限度重用现有的随机接入中的TA设计和TA更新或调整时的TA调整信令设计，降低了标准化工作量。
-本申请中的方法充分考虑了在一个子帧(subframe)中的长CP的OFDM符号和短CP的OFDM符号对整数位TA调整的影响，保证了TA调整后的OFDM符号对齐，使得接收机可以通过相同FFT窗进行接收，避免了多用户间干扰并降低接收机复杂度。
-本申请中的方法可以使得TA调整/更新时的调整的最小粒度进行改变，从而满足不同的时延需求；另一方面，也可以允许用户设备自行选着TA调整/更新值，从而解决了在卫星相对用户设备高速运动(比如LEO)情况下TA更新不及时的问题。
