Patent ID: 8843171

Claim:
A transmission power control method for controlling uplink transmission power, wherein the method enables one of a common control mode for controlling transmission power of a plurality of antennas using a transmission power control signal common to the antennas for a mobile station apparatus having the plurality of antennas, and an individual control mode for controlling transmission power of the plurality of antennas using transmission power control signals for individual antennas for the mobile station apparatus, wherein, in the common control mode, the transmission power control signal common to the antennas is generated based on a difference between an average value of reception quality of each of the plurality of antennas of the mobile station apparatus, and target reception quality, and wherein, in the individual control mode, each of the transmission power control signals for individual antennas is generated based on a difference between reception quality of each of the plurality of antennas of the mobile station apparatus, and target reception quality.
