Patent ID: 6865168

Claim:
A communication station for transmitting first data and second data, comprising: an encoder for coding the first data and the second data; a multiplexer for multiplexing the coded first data and the coded second data; a transmitter for transmitting a signal including the first data and the second data that are multiplexed with each other to another communication station, the first data and the second data being transmitted at a first transmission power level and a second transmission power level, respectively; and a transmission power controller for receiving transmission power control information from the other communication station and for controlling one of the first transmission power level and the second transmission power level independently of the other, wherein the transmission power control information is generated in such a manner as to reduce a difference between a first difference between a required received quality and an actual received quality of the first data and a second difference between a required received quality and an actual received quality of the second data.
