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
对于3GPP(3rd GenerationPartner Project，第三代合作伙伴项目)系统，在RRC(Radio Resource Control，无线资源控制)连接(RRC_CONNECTED)态，基站负责维护用于维持L1(layer 1，层一)同步的定时提前量。具备相同定时提前量并且使用同一个定时参考的小区被分在一个TAG(Timing Advance Group，定时提前组)，每个TAG包括至少一个被配置上行链路的服务小区(Serving Cell)，RRC层负责每个服务小区到TAG的映射。对于PTAG(Primary TAG)，SpCell(Special Cell，特殊小区)是PTAG中的小区的定时参考，对于一个STAG(Secondary TAG)，这个STAG中的任一被激活的SCell(Secondary Cell，辅小区)作为这个STAG中的小区的定时参考(Timing Reference Cell)。定时提前更新通过MAC(Medium Access Control，媒体接入控制)CE(Control Element，控制元素)命令由基站通知UE。如果L1被认为不同步，UE(User Equipment，用户设备)只能在上行链路发送MSG1(Message 1，消息1)或者MSGA(Message A，消息A)。
发明内容
一个定时参考在某些情况不能继续作为定时参考，比如，当PCell(Primary Cell，主小区)执行基于L3(layer 3，层三)信令的切换时，或者，当PSCell(Primary SCG(Secondary Cell Group，辅小区组)Cell，SCG主小区)执行基于L3信令的PSCell更改时，或者，当作为定时参考的SCell被去激活时，UE需要更改定时参考。当UE从一个小区的覆盖区域移动到另一个小区的覆盖区域时，需要执行服务小区的更改，定时参考是预定义的，或者，定时参考是UE选择的，基站不能决定定时参考的选择。现有协议中，服务小区更改是被L3测量触发的，并且通过RRC信令触发PCell(Primary Cell，主小区)和PSCell的同步重配置，并且会触发释放SCell，这些操作会涉及L2(layer 2，层二)和L1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移动性增强或者连续的CPC(Conditional PSCell Change)机制降低时延、开销和中断时间是一个重要的研究方向，会导致服务小区的频繁更改。当服务小区频繁更改时，定时参考也会频繁更改，从而导致从而对上行链路传输会产生影响。因此，针对服务小区变换较快的场景，如何确定定时参考需要进行增强。
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。
