METHOD FOR CONTROLLING TRANSMISSION POWER OF CONTROL CHANNEL IN WIRELESS COMMUNICATION TERMINAL

摘要

PURPOSE: A method for controlling the transmission power of a control channel in a wireless communication terminal is provided to efficiently control the transmission power of the second uplink control channel capable of being received in two or more cell base stations for helping the demodulation of the first uplink control channel. CONSTITUTION: If a signal is transmitted to the first uplink control channel for controlling a downlink shared channel provided from one cell, the transmission power of the second uplink control channel is adjusted upward. If the signal transmission to the first uplink control channel is completed, the transmission power of the second uplink control channel is reduced.
