Abstract: A beam alignment method includes receiving, at a current location by using a plurality of receive beams, a transmit beam from a network device, and determining reference signal received power (RSRP) of each of the plurality of receive beams; selecting an optimal receive beam from the plurality of receive beams based on the RSRP; determining, based on the optimal receive beam, a rotation angle and a rotation direction for a terminal device to align a peak direction beam with the transmit beam; and adjusting a location of the terminal device based on the rotation angle and the rotation direction, and forming an optimal beam pair by using the peak direction beam and the transmit beam at an adjusted location.
