The present disclosure provides a satellite communication method and apparatus based on a time division duplex (TDD) frame structure design. The solution is: determining a preset time division duplex (TDD) frame structure group corresponding to a base station, wherein the preset TDD frame structure group includes a first TDD frame structure and a second TDD frame structure generated after frame header offsetting is performed on the first TDD frame structure; in response to receiving a first message transmitted by a terminal, determining a UE set to which the terminal belongs, wherein the UE set is a first UE set or a second UE set; if the terminal belongs to the first UE set, scheduling the terminal based on the first TDD frame structure; and if the terminal belongs to the second UE set, scheduling the terminal based on the second TDD frame structure.
