阅读说明：本技术 Bwp切换方法和终端设备 (BWP switching method and terminal device ) 是由 徐伟杰 卢前溪 于 2019-07-05 设计创作，主要内容包括：本申请实施例提供了一种BWP切换方法和终端设备,终端设备可以基于下行参考信号的测量,实现自主的下行BWP和/或上行BWP切换,从而解决卫星通信中由于卫星波束的快速切换导致的BWP快频繁切换对卫星的通信性能的影响。该BWP切换方法包括：终端设备测量多个下行BWP所对应的多个下行参考信号；该终端设备根据该多个下行BWP所对应的多个下行参考信号的测量结果,确定是否从第一下行BWP切换至第二下行BWP,其中,该第一下行BWP为激活的BWP,该第一下行BWP和该第二下行BWP属于该多个下行BWP。(The embodiment of the application provides a BWP switching method and a terminal device, wherein the terminal device can realize autonomous downlink BWP and/or uplink BWP switching based on measurement of a downlink reference signal, so that the influence of fast and frequent switching of BWP on communication performance of a satellite due to fast switching of satellite beams in satellite communication is solved. The BWP switching method includes: the terminal equipment measures a plurality of downlink reference signals corresponding to a plurality of downlink BWPs; the terminal device determines whether to switch from a first downlink BWP to a second downlink BWP according to measurement results of a plurality of downlink reference signals corresponding to the plurality of downlink BWPs, where the first downlink BWP is an active BWP, and the first downlink BWP and the second downlink BWP belong to the plurality of downlink BWPs.)
