POWER TRANSMISSION CONTROL METHOD AND MOBILE STATION DEVICE.

摘要

Provided are a power transmission control method capable of appropriately controlling the transmitted power of a mobile station device having a plurality of transmission antennas, and a mobile station device. Power transmission control of an uplink of a mobile station device having a plurality of transmission antennas involves the following steps: a step for measuring the path loss (PL) of at least one of a plurality of transmission antennas; a step for setting the representative path loss (PL') based on the measured path loss; a step for determining the total transmitted power (PTX) of the mobile station device based on the representative path loss (PL'); and a step for determining the transmitted power (PTXn) of each transmission antenna by distributing the total transmitted power (PTX) to the plurality of transmission antennas.
