Abstract
Two power control loops for antenna switching transmit diversity are realized by a user terminal including two antennas (), one power amplifier () for amplifying the signals to be transmitted from each of the antennas, and a switch () switching the transmission power of the power amplifier from one antenna to the other antenna. Accordingly, the user terminal is enabled to alternately transmit data packets, with its two antennas. A closed loop power control mechanism in the user terminal is adapted to update, on receipt of a transmission power control command from a base station, the transmission power relative to the level of two slots previously.
