阅读说明：本技术 波束失败恢复方法、装置和通信系统 (Beam failure recovery method, device and communication system ) 是由 陈哲 宋磊 杨现俊 张磊 王昕� 于 2019-03-28 设计创作，主要内容包括：本申请提供一种波束失败恢复方法、装置和通信系统,该装置包括：接收单元,在终端设备接收到与波束失败恢复相关的响应(BFR response)的一段时间之后,直至激活或重配置信令之前,所述接收单元在所述终端设备的第一小区中根据与选择出的参考信号(q-new)或高层指示的参考信号(q-new)相同的天线准共址(QCL)参数监听和/或接收下行信号。根据本申请,终端设备能有足够的时间可靠地进行波束方向的切换,从而提升系统性能。(The application provides a method, a device and a communication system for recovering beam failure, wherein the device comprises: a receiving unit which monitors and/or receives a downlink signal according to the same antenna quasi-co-location (QCL) parameter as the selected reference signal (q _ new) or the reference signal (q _ new) indicated by a higher layer in a first cell of a terminal device after a period of time when the terminal device receives a response (BFR response) related to beam failure recovery until activation or reconfiguration signaling. According to the method and the device, the terminal equipment can have enough time to reliably switch the beam direction, so that the system performance is improved.)
