Description

一种被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，尤其涉及移动性的传输方法和装置。
背景技术
当UE(User Equipment，用户设备)从一个小区的覆盖区域移动到另一个小区的覆盖区域时，需要执行服务小区(Serving Cell)的更改。现有协议中，服务小区更改是被L3(layer 3，层三)测量触发的，并且通过RRC(Radio Resource Control，无线资源控制)信令触发PCell(Primary Cell，主小区)和PSCell(Primary SCG(Secondary Cell Group，辅小区组)Cell，SCG主小区)的同步重配置，并且会触发释放SCell(Secondary Cell，辅小区)，这些操作会涉及L2(layer 2，层二)(和L1(layer1，层一))重置(reset)，导致更长的时延(Delay)、更大的开销(Overhead)和更长的中断时间(interruption time)。在Rel-18，针对移动性增强是3GPP(3rd GenerationPartner Project，第三代合作伙伴项目)很重要的研究方向，3GPP RAN94e次会议决定开展“NR(New Radio，新空口)移动性进一步增强(Further NR mobility enhancements)”研究项目(Work Item，WI)。其中，通过基于L1/L2信令的L1/L2移动性增强降低时延、开销和中断时间是一个重要的研究方向。
发明内容
对于一个小区组中的多个服务小区，根据是否具备相同的定时提前量可以被配置不同的TAG(Timing Advance Group，定时提前组)。对于PTAG(Primary TAG)，SpCell(Special Cell，特殊小区)是PTAG中的小区的定时参考小区，对于一个STAG(Secondary TAG)，这个STAG中的任一被激活的SCell作为这个STAG中的小区的定时参考小区。当UE通过L3信令从源SpCell更换到目标SpCell时，UE会重置MAC(Medium Access Control，媒体接入控制)实体并且认为整个小区组中的SCell被去激活，从而导致整个小区组的上行链路失步，UE需要通过随机接入(Random Access)过程重新获取目标小区组的上行链路定时。由于L1/L2的移动性基于L1测量和上报，在小区间的移动会更加频繁，如何维持上行链路同步以保证上行链路传输需要进行增强。
针对上述问题，本申请提供了一种针对L1/L2的移动性维持上行链路同步的解决方案。针对上述问题描述中，采用基于L1/L2的移动性场景作为一个例子；本申请也同样适用于例如基于L3的移动性场景，取得类似基于L1/L2的移动性中的技术效果。进一步的，虽然本申请的初衷是针对Uu空口，但本申请也能被用于PC5口。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于V2X(Vehicle-to-Everything，车联网)场景，终端与中继，以及中继与基站之间的通信场景，取得类似的终端与基站场景中的技术效果。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于IAB(Integrated Access and Backhaul，集成接入和回传)的通信场景，取得类似的终端与基站场景中的技术效果。进一步的，虽然本申请的初衷是针对地面网络(Terrestrial Network，地面网络)场景，但本申请也同样适用于非地面网络(Non-Terrestrial Network，NTN)的通信场景，取得类似的TN场景中的技术效果。此外，不同场景采用统一解决方案还有助于降低硬件复杂度和成本。
