Abstract
Disclosed are a method and an apparatus for determining a Guard Period (GP) in a Time Division Duplexing (TDD) system. A communication method based on Time Division Duplexing (TDD) includes: determining, by a base station, a guard period based on information on a distance between user equipment and the base station; and performing, by the base station, downlink transmission to the user equipment based on the determined guard period, wherein the guard period is determined based on one of a default guard period mode, a reduced guard period mode, and a zero guard period mode, and the reduced guard period mode is a mode for setting a reduced guard period, which is shorter than the default guard period set based on the default guard period mode, and the zero guard period mode is a mode for setting a length of the guard period to 0.
