Abstract
A method and apparatus for controlling uplink transmission power in a mobile communication system are provided. In the method, an Advanced Mobile Station (AMS) determines uplink transmission power based on a measured path loss, an uplink noise and interference level received from an Advanced Base Station (ABS), a target Signal-to-Noise and Interference Ratio (SINR), and an offset. An initial offset value is determined based on a number of retransmissions of an initial ranging code performed until an initial ranging process is completed, a transmission power unit used for retransmission of the initial ranging code, and a power correction value received from the ABS upon completion of the initial ranging process with the ABS.
