A method for transmit power adjustment in a user equipment of a wireless communications system, the method comprising: performing uplink transmission by means of beamforming, such that simultaneous uplink transmission from a plurality of antennas (a 1, a 2, aN) of the user equipment is carried out; performing a first transmit power adjustment phase, wherein the first transmit power adjustment phase comprises: decreasing the transmit power of a selected antenna (a 2) by a selected decrease amount during a first measurement period, wherein the transmit power of the selected antenna prior to the decrease was lower than or equal to the transmit power of another antenna (ai) of the plurality of antennas; analyzing a plurality of transmit power control, TPC, commands corresponding to the first measurement period to determine a result of the decreased transmit power of the selected antenna (a 2) indicating a change in received power at a base station; and completing the first transmit power adjustment phase by selectively (i) resuming the transmit power of the selected antenna (a 2) prior to the decrease by the decrease amount, if the result of the decreased transmit power is above or equal to a decrease threshold value or (ii) continuing the uplink transmission with the decreased transmit power of the selected antenna if the result of the decreased transmit power indicates a change in received power at the base station which is below the decrease threshold value. performing uplink transmission by means of beamforming, such that simultaneous uplink transmission from a plurality of antennas (a 1, a 2, aN) of the user equipment is carried out; performing a first transmit power adjustment phase, wherein the first transmit power adjustment phase comprises: decreasing the transmit power of a selected antenna (a 2) by a selected decrease amount during a first measurement period, wherein the transmit power of the selected antenna prior to the decrease was lower than or equal to the transmit power of another antenna (ai) of the plurality of antennas; analyzing a plurality of transmit power control, TPC, commands corresponding to the first measurement period to determine a result of the decreased transmit power of the selected antenna (a 2) indicating a change in received power at a base station; and completing the first transmit power adjustment phase by selectively (i) resuming the transmit power of the selected antenna (a 2) prior to the decrease by the decrease amount, if the result of the decreased transmit power is above or equal to a decrease threshold value or (ii) continuing the uplink transmission with the decreased transmit power of the selected antenna if the result of the decreased transmit power indicates a change in received power at the base station which is below the decrease threshold value. decreasing the transmit power of a selected antenna (a 2) by a selected decrease amount during a first measurement period, wherein the transmit power of the selected antenna prior to the decrease was lower than or equal to the transmit power of another antenna (ai) of the plurality of antennas; analyzing a plurality of transmit power control, TPC, commands corresponding to the first measurement period to determine a result of the decreased transmit power of the selected antenna (a 2) indicating a change in received power at a base station; and completing the first transmit power adjustment phase by selectively (i) resuming the transmit power of the selected antenna (a 2) prior to the decrease by the decrease amount, if the result of the decreased transmit power is above or equal to a decrease threshold value or (ii) continuing the uplink transmission with the decreased transmit power of the selected antenna if the result of the decreased transmit power indicates a change in received power at the base station which is below the decrease threshold value.
