Abstract

An information reporting method includes: reporting, by a terminal, a first timing difference to a serving cell base station, where the first timing difference is a difference between a first propagation delay and a second propagation delay, the first propagation delay is a propagation delay between the terminal and a serving cell satellite, and the second propagation delay is a propagation delay between the terminal and a neighboring cell satellite.
