ABSTRACT:
A method and apparatus for determining a power control target setpoint and transmission power of a secondary pilot signal for power control and channel estimation on a signal transmitted in a reverse direction in a mobile communication system. A mobile station determines transmission power of a secondary pilot signal based on a data rate of a reverse traffic channel to be transmitted. A base station adjusts a power control target setpoint according to received reverse data rate information, and performs channel estimation (or channel compensation) using a primary pilot signal and a secondary pilot signal (or a reverse rate indicator (RRI) channel signal).
