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
传统的网络控制(Network Controlled)的移动性(mobility)包括小区级的移动性(cell level)和波束级的移动性(beam level)，其中，小区级的移动性依赖于RRC(Radio Resource Control，无线资源控制)信令，波束级的移动性不涉及RRC信令。3GPP(the 3rd Generation Partnership Project，第三代合作伙伴项目)R16之前，波束级的移动性仅针对小区单个小区内的波束管理(Beam Management)等。3GPPRAN#80次会议决定开展“Further enhancements on MIMO for NR”工作项目(Work Iterm，WI)，支持多波束(multi-beam)操作(operation)，针对以层一(Layer 1，L1)/层二(Layer 2，L2)为中心的小区间移动性(L1/L2-centric inter-cell mobility)以及小区间多TRP(multiple Transmit/Receive Point，mTRP)进行增强。
发明内容
为实现inter-cell L1/L2 mobility或者inter-cell mTRP，当UE(User Equipment，用户设备)在服务小区时，网络通过RRC消息给UE配置另一个小区的无线参数，UE在服务小区(Serving cell)的覆盖范围内，可以使用另一个小区的TRP进行数据传输，另一个小区和服务小区具有不同的PCI(Physical Cell Identifier，物理小区标识)。当UE在服务小区内使用另一个小区的TRP进行数据传输时，如果采用当前的无线链路监测(Radio Link Monitoring)机制，会导致过早触发无线链路失败(Radio Link Failur，RLF)，影响UE性能。因此，需要针对无线链路监测机制进行增强。
针对上述问题，本申请提供了一种解决方案。针对上述问题描述中，采用uu口场景作为一个例子；本申请也同样适用于例如副链路(sidelink)场景，取得类似uu口场景中的技术效果。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。
