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.

Two power control loops for antenna switching transmit diversity

The subject matter relates to a method for transmitting data in packets in a radio communications system, according to which the receipt of data packets from at least two terminals is confirmed by a base station of the radio communications. The confirmation of receipt takes place without an overlap in time, using identical resources.
