1. A communication method, comprising:
receiving, by a terminal, first information by using a serving beam,
wherein the first information indicates a delay compensation parameter corresponding to a target beam, and
the serving beam and the target beam are different beams;
determining, by the terminal based on a full timing advance and the delay compensation parameter corresponding to the target beam,
a differential timing advance corresponding to the target beam; and
determining, by the terminal, the full timing advance based on location information of the terminal and location information of a target satellite,
wherein the target satellite corresponds to the target beam; or
determining, by the terminal, the full timing advance based on a delay compensation parameter corresponding to the serving beam and
a differential timing advance corresponding to the serving beam.
