Abstract: PURPOSE: A terminal and a communication method thereof are provided to reduce interference between multi-functional terminals attempting to operate as a base station. CONSTITUTION: A multi-functional terminal capable of operating in a base station mode selects a first back-off delay time when entering a station mode. The multi-functional terminal transmits a preamble when the first back-off delay time finishes, unless the multi-functional terminal receives the preamble from another multi-functional terminal or a base station before the first back-off delay time finishes (S340). The multi-functional terminal selects a second back-off delay time (S350). The multi-functional terminal operates as the base station mode when the second back-off delay time finishes, unless the multi-functional terminal receives the preamble from another multi-functional terminal or a base station before the second back-off delay time finishes (S380). [Reference numerals] (AA,CC) Yes; (BB,DD) No; (S310) Select a first back-off delay time when entering a station mode and start a first back-off time; (S320) Whether or not a preamble is received from a different multi-functional terminal or the station?; (S330) Operate by a lower terminal; (S340) Transmit the preamble when the first back-off delay time finishes; (S350) Select the first back-off delay time and start a second back-off time; (S360) Whether of nor the preamble is received from the different multi-functional terminal or the station?; (S370) Operate by a lower terminal; (S380) Operate by the station mode when the second back-off time finishes
