Description

一种被用于无线通信的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其是涉及支持BWP(Bandwidth Part，带宽区间)动态转换(Dynamic Switch)的无线信号的传输方法和装置。
背景技术
目前，5G NR(New Radio Access Technology，新无线接入技术)的技术讨论正在进行中。相比LTE(Long-Term Evolution，长期演进)及LTE-A(Long-Term Evolution Advanced，增强的长期演进)，5G系统中引入了BWP(Bandwidth Part，频带部分)的概念，即当一个小区拥有一个带宽较大的CC(Component Carrier)时，基站可以将所述较大的CC拆分成多个BWP以适应接收带宽和发送带宽能力较小的UE(User Equipment，用户设备)，当所述带宽能力较小的UE与小区通信时，所述UE仅仅在一个BWP上进行下行接收或者上行发送。同时，为提高BWP的配置灵活性和实时性，2017年9月的RAN1AH_Hoc会议上通过了采用包含调度的DCI(Downlink Control Information)动态转换(Dynamic Switch)BWP的方案。
于此同时，5G系统中，BR(Beam Recovery，波束恢复)以及BLF(Beam Link Failure,波束链路失败)的概念正在被讨论中，UE检测当前的多个服务波束(Serving Beam)以获得动态调度，当UE检测的多个服务波束信道质量变差时，UE向基站发送BRR(Beam Recovery Request，波束恢复请求)以请求新的波束资源以监测物理层控制信令。
因此，当用户设备在多个BWP之间动态切换时，上述BLF的检测和维护过程需要被重新考虑。
发明内容
5G系统中，当一个用户在多个频带上被服务时，一种直观的BR的流程是在所有服务频带中的所有服务波束上进行检测以确保不会发生 BLF，以及如果检测到BLF后分别在多个频带上触发BR的过程。上述方法的一个缺点就是当UE是频带受限时，UE不能同时在多个频带进行检测，进而会增加BR过程消耗的时间，且对UE的功耗和复杂度要求较高。目前，QCL(Quasi Co-located，准共址)的概念在波束赋形传输中被广泛使用。当两个天线端口被认为是QCL时，所述两个天线端口所发出的无线信号的{平均时延(Average Delay)、多普勒频偏(Doppler Shift)、空间接收参数(Spatial RX Parameters)}被认为是一样的，进而所述两个天线端口被认为具有相同的空间特性。当一个基站存在多个频带资源时，且某些位于不同频带资源上的天线端口依然具有QCL的特性时，所述QCL的特性可用于BLF的确定和BR的过程中。
针对上述问题，本申请公开了一种解决方案。在不冲突的情况下，本申请的用户设备中的实施例和实施例中的特征可以应用到基站中，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。
