Uplink transmission power offset and the fast forward common channel power level of the transmitting and receiving apparatus and method in a communication system using a high-speed forward packet access system

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for transmitting and receiving uplink transmission power offset and a high-speed downlink shared channel power level in a communication system employing a high-speed downlink packet access system.;SOLUTION: An apparatus for controlling uplink transmission power in the high-speed packet data communication system is constituted of a channel condition determiner that measures a signal-to-interference ratio of a first uplink dedicated channel signal received from a UE and calculates a difference between the measured signal-to-interference ratio and a preset target signal-to-interference ratio, a transmission power determiner that compares the difference with preset thresholds and determines an uplink power offset to be applied to a second uplink dedicated channel transmitting control information for packet data received at the UE according to a result of the comparison, and a transmitter that transmits over a downlink the determined uplink power offset to the UE.;COPYRIGHT: (C)2003,JPO
