Abstract: The present invention relates to the technical field of wireless communications, and in particular, to a beam training method and device, for use in resolving the problems in the prior art of excessive time-consuming of a beam training process, large overhead of training signals, and relatively low efficiency. According to embodiments of the present invention, a transmit device sends beam training signals in two times. The first sending of a transmit beam training signal is for a receive device to select a transmit beam using a selected receive beam and report the transmit beam. The second sending is that the transmit device sends a receive beam training signal according to the transmit beam information report of the receive device, so as to train the received beam of the receive device. According to the embodiments of the present invention, an interactive beam training method is used to gradually search for the best transmit beam and receive beam, thereby avoiding completing beam training all at once, reducing beam training time and overhead, and improving efficiency.
