Apparatus and method for controlling uplink transmission power in a mobile communication system

摘要

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.

1. A method for controlling uplink power at a mobile station (MS) in a mobile communication system, the method comprising:
determining uplink power based on a path loss, an uplink noise and interference level, a target signal-to-interference and noise ratio (SINR), and an offset, wherein an initial value of the offset is determined based on a number of ramp-ups to be processed until an initial ranging process is completed, a power step size to ramp-up, and a power adjustment value received from a base station (BS).
