Abstract
A method and mobile communication station for communicating orthogonal frequency division multiplexed (OFDM) symbols uses two or more antennas. The antenna parameters are set for beamforming, a transmit power level is initially set, and subcarrier modulation assignments are selected after the antenna parameters and the transmit power level are set to achieve a quality-of-service level for a particular application and data type of a service flow. The transmit power level may also be set based on a desired cell size.
