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，尤其涉及传输延迟较大的***中定时同步的方法和装置。
背景技术
针对迅猛发展的车联网(Vehicle-to-Everything，V2X)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作。目前3GPP已经完成了面向5G V2X业务的需求制定工作，并写入标准TS22.886中。3GPP为5G V2X业务定义了4大应用场景组(Use Case Groups)，包括：自动排队驾驶(Vehicles Platnooning)，支持扩展传感(Extended Sensors)，半/全自动驾驶(Advanced Driving)和远程驾驶(Remote Driving)。目前的V2X***中，同时支持基于基站配置时频资源用于V2X传输，以及V2X的发送端通过感知测量(Sensing Measurement)确定时频资源用于V2X传输。
与此同时，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
NTN网络具有覆盖广的优势，当NTN结合V2X技术时，NTN网络能够为地面基站覆盖不到的地理位置配置用于V2X传输的时频资源，随后V2X终端间基于基站配置信令确定实际传输的时频资源。Rel-12的D2D(Device to Device，设备到设备)传输中，基站一般会为整个小区配置统一的用于D2D传输的时域资源，以避免对Uu口(对应蜂窝链路)的影响；因为基站覆盖下的用户到基站的延迟都较小，往往不会超过一个多载波符号的持续时间，进而认为离基站较远的UE(User Equipment，用户设备)和离基站较近的UE在统一配置的D2D时域资源下，不会对终端本身的Uu口产生影响。然而当把V2X引入NTN网络中时，由于不同UE之间的TA(Timing Advance，定时提前)存在很大的差异，甚至达到几个甚至十几个毫秒，如果沿用Rel-12的方式，当基站配置统一的V2X时域资源时，较大的TA差异会导致某些UE的Uu传输会偏移到其它UE的V2X链路上，进而导致干扰。
针对上述问题的一个简单方法，就是为不同的TA用户配置时域差距足够远的V2X时域资源，以避免Uu口的传输偏移到PC-5口(对应副链路)上，然后此种方式会造成过多的资源不可被Uu口调度，且降低频谱效率。针对上述问题，本申请公开了一种解决方案，需要说明的是，在不冲突的情况下，本申请的第一节点和第三节点的实施例和实施例中的特征可以应用到基站中，且本申请中的第二节点的实施例和实施例中的特征可以应用到终端中。与此同时，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。
