摘要: This disclosure discloses a beam switching method and an apparatus. A terminal device receives first indication information from a network device, where the first indication information indicates a first beam. Then, the terminal device performs one or more of the following behaviors based on the first beam: measuring downlink time-frequency offset information and path loss information corresponding to the first beam, sending, based on the first beam, a signal for uplink timing measurement, and receiving uplink timing adjustment information from the network device, where the timing adjustment information is determined based on the first beam. Further, the terminal device receives second indication information from the network device, where the second indication information indicates to switch to the first beam. The terminal device first measures timing information and/or the path loss information of the first beam to be switched to.
