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系统中的传输方法和装置，尤其涉及波束管理和链路恢复的传输方案和装置。
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单个小区内的波束管理(Beam Management)等。3GPP RAN#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
针对NR系统，3GPP引入了BFR(Beam Failure Recovery，波束失败恢复)机制，UE(User Equipment，用户设备)根据属于服务小区的一个参考信号集合进行评估，如果评估结果比预定门限差的次数达到一个预定数值，触发BFR或者随机接入(Random Access，RA)过程。为实现inter-cell L1/L2mobility或者inter-cell mTRP，当UE在服务小区(Serving Cell)时，网络通过RRC消息针对服务小区给UE配置至少一个附加小区，UE在服务小区的覆盖范围内，可以使用附加小区的TRP进行数据传输，附加小区和服务小区具有不同的PCI(Physical Cell Identifier，物理小区标识)。
现有的NR系统中，用于确定是否触发BFR机制的测量用的参考信号资源集合，以及用于选择上报的候选参考信号资源集合都通过网络侧配置获得，终端设备不会去触发更改上述两个参考信号资源集合。而在波束管理过程中，终端能够根据上报的参考信号资源所关联的PCI隐性告知基站其位于哪一个TRP的覆盖之下，进而上述波束管理过程中上报的参考信号资源能够被应用到BFR中，以提高BFR流程的效率。
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。本申请也同样适用于面临相似问题的其它场景(例如自组织网络，或者中心节点是非基站节点的场景，或者高速移动场景，或者针对不同的应用场景，比如eMBB和URLLC，也可以取得类似的技术效果。此外，不同场景(包括但不限于eMBB和URLLC的场景)采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中，反之亦然。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS(Technical Specification)36系列、TS38系列、TS37系列中的定义。
