A wireless communication includes determining, by a satellite, at least one first signal, sending the at least one first signal to a terminal based on at least one first beam, and receiving a random access request from the terminal. Each first signal of the at least one first signal corresponds to one first beam of the at least one first beam. Each first signal of the at least one first signal includes information about a first geographical location of a center point of the one first beam of the at least one first beam corresponding to each first signal of the at least one first signal. The information about the first geographical location is useable to determine a second beam from the at least one first beam. The random access request includes an identifier of the second beam.
