Claim Text:
1. A method in a user equipment for adjusting signals transmitted an uplink to a network node, based on a feedback value received from the network node, the method comprising: transmitting a signal to the network node, receiving a feedback signal from the network node that provides feedback in response to the signal that was transmitted, obtaining a time delay value of the feedback signal that was received, determining, when adjusting the signals transmitted in the uplink, if the received feedback signal is related to the uplink signal transmitted on a transmission antenna of at least two transmission antennas used for uplink transmission based on the time delay value, and adjusting signals transmitted in the uplink based on the value of the time delay of the feedback signal to compensate for the time delay value of the feedback signal and by selecting one transmission antenna of the at least two transmission antennas to be used for uplink transmission, based on the feedback signal related to the transmission antenna used for uplink transmission.
