Abstract
The present invention relates to a device for controlling a power level to control contention between mobile terminals in an uplink contention period in an orthogonal frequency division multiplexing access (OFDMA) system, and a method thereof. In the method, cell broadcasting information broadcasted from the base station is received by the mobile terminal, the transmission power information of the base station is obtained from the cell broadcasting information by the mobile terminal, a received power level of the received cell broadcasting information is obtained by the mobile terminal, transmission power of a signal transmitted to the base station is determined based on the transmission power information and the received power level, and the signal is transmitted to a contention period based on the determined transmission power.
