Embodiments of the present invention provide a wireless communications method and apparatus. The method includes: receiving, by a first device, at least two pieces of timing advance TA information, where the at least two pieces of TA information are corresponding to at least two beams of the first device on a same carrier; and performing, by the first device, timing adjustment on transmission on the at least two beams based on the at least two pieces of TA information. By using the foregoing technical solution, interference caused by asynchronous signals can be reduced or avoided.
