TERMINAL EQUIPMENT AND METHOD FOR CONTROLLING UPLINK TRANSMISSION POWER

摘要

The present invention relates to terminal equipment and a method for controlling uplink transmission power. The method, in which terminal equipment controls uplink transmission power in a wireless communication system, includes the steps of: determining uplink transmission power for at least one type of channel when the one type of channel is employed for simultaneous transmission at a predetermined cell among a first type of channel corresponding to a plurality of PUCCHs (Physical Uplink Control Channels), a second type of channel corresponding to PUSCHs (Physical Uplink Shared Channels) including a plurality of pieces of UCI (Uplink Control Information), and a third type of channel corresponding to PUSCHs excluding the plurality of pieces of UCI; and transmitting the at least one type of channel via the determined uplink transmission power, wherein the uplink transmission power is determined by applying a scaling factor to a power value of the at least one type of channel when the uplink transmission power exceeds the maximum transmission power with which the terminal can transmit or the transmission power remaining in the terminal equipment.
