POWER TRANSMISSION CONTROL METHOD AND MOBILE STATION DEVICE |
摘要 |
The present invention is directed to providing a transmission power control method and a mobile station apparatus that can adequately control the transmission power of a mobile station apparatus having a plurality of transmitting antennas. Uplink transmission power control for a mobile station apparatus having a plurality of transmitting antennas provides a step of measuring the path loss (PL) of at least one transmitting antenna in a plurality of transmitting antennas, a step of setting representative value path loss (PL') based on the measured path loss values, a step of determining the total transmission power (P TX ) of the mobile station apparatus based on the representative value path loss (PL'), and a step of determining the transmission power (P TXn ) of each transmitting antenna by distributing the total transmission power (P TX ) to the plurality of transmitting antennas. |
