Abstract: This application provides a method for processing timing advance (TA) of a terminal, and an apparatus. A terminal obtains a correspondence between first TA and a beam, determines, based on the correspondence, the beam corresponding to the first TA, and further determines, based on the beam corresponding to the first TA, whether the first TA is invalid. According to this application, the terminal may determine, by using a finer granularity, whether the first TA is invalid, and this helps trigger selection of more appropriate TA, thereby further reducing interference between uplink transmission.
