METHOD FOR CONTROLLING UPLINK TRANSMISSION POWER BY A TERMINAL THAT ADOPTS A TIME DIVISION DUPLEX (TDD) SCHEME IN A WIRELESS COMMUNICATION SYSTEM, AND TERMINAL DEVICE THEREOF

摘要

Disclosed are a method for controlling uplink transmission power by a terminal that adopts a time division duplex (TDD) scheme in a wireless communication system, and a terminal device thereof. The method for controlling uplink transmission power by a terminal that adopts a TDD scheme in a wireless communication system comprises the steps of: determining, when the ratio of the number of downlink subframes to the number of uplink subframes changes in said TDD scheme, uplink transmission power to be transmitted from at least one uplink subframe within a changed first frame; and transmitting an uplink signal in said at least one uplink subframe according to said determined uplink transmission power.
