APPARATUS AND METHOD FOR UPLINK POWER CONTROL IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2010/050776

Kind Code:

A3

Abstract:

An apparatus and method for controlling a transmit power of a sounding signal in a wireless communication system are provided. The method includes estimating a downlink Carrier to Interference and Noise Ratio (CINR) using at least one signal received from a Base Station (BS), determining a transmit power level for a sounding signal using a target CINR for the sounding signal, wherein the target CINR is determined based on the downlink CINR and multi-target CINR information, and transmitting the sounding signal according to the transmit power level.
