Abstract

The present invention relates to a method and a user equipment for use in a wireless communication system. The method and user equipment allow for transmit power adjustment of the transmit power of a selected of a plurality of antennas of the user equipment. The method comprised a transmit power adjustment phase during which it is test (23) is performed to decrease the transmit power of the selected antenna. A number of TPC commands are then analyzed (24) to determine a result of the decreased transmit power indicating a change in received power at a base station. Based on the determined result it is decided to continue (27) with the decreased transmit power or to resume (26) the previous transmit power of the selected antenna after completion of the transmit power adjustment phase.
