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，尤其是支持蜂窝网的无线通信系统中的无线信号的传输方法和装置。
背景技术
在LTE(Long-term Evolution，长期演进)系统中，传统的网络控制的移动性(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)R(Release，版本)16之前，波束级的移动性仅针对单个小区内的波束管理(Beam Management)。3GPP RAN(Radio Access Network，无线接入网)#80次会议决定开展针对以层一/层二(L1/L2)为中心的小区间移动性/波束管理(L1/L2-centric inter-cell mobility/beam management)和小区间多TRP(Transmit/Receive Point)的研究。
发明内容
在L1/L2为中心的小区间移动性和小区间多TRP的讨论中，网络给UE(User Equipment，用户设备)配置至少一个附加小区，UE可以利用附加小区更好的链路质量进行传输。在此场景下，当UE的下行物理层信道或信号(例如但不限于CSI-RS)与附加小区的同步信号在时域交叠时，UE用什么QCL(Quasi Co-Location，准共址)关系来接收下行物理层信道或信号，是需要解决的问题。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然上述描述采用蜂窝网作为例子，本申请也适用于其他场景比如副链路(Sidelink)传输，并取得类似在蜂窝网中的技术效果。此外，不同场景(包括但不限于蜂窝网和副链路传输)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，本申请的第一节点中的实施例和实施例中的特征可以应用到第二节点中，反之亦然。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。
