1. A satellite communication method based on a time division duplex (TDD) frame structure design, applicable to a network device, characterized by comprising:
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 by performing frame header offsetting 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.
