Abstract:
1. A method for controlling an uplink transmission power value by a mobile station in a wireless mobile communication system, the method comprising: receiving, information including a number representing a total count of mobile stations allocated to a given time-frequency resource region, from a base station; receiving, a noise and interference (NI) level estimated by the base station, from the base station; determining the uplink transmission power value by using the NI level, a power adjustment value and a reference transmission power value, wherein the power adjustment value is obtained based on the received number, wherein the reference transmission power value is equal to a transmission power value of the mobile station when only the mobile station transmits an uplink signal through the given time-frequency resource region, and wherein the determined uplink transmission power value is represented as a dBm value per subcarrier; and transmitting the uplink signal through the given time-frequency resource region based on the determined uplink transmission power value.
