摘要:
Method and arrangement (600) in a user equipment (110) for adjusting signals transmitted in uplink to a network node (120), based on a feedback value received from the network node (120). The method comprises transmitting (501) a signal, to be received by the network node (120). Further, the method comprises receiving (502) a feedback signal from the network node (120), providing feedback on the transmitted (501 ) signal. In addition, the method comprises obtaining (503) a value of a time delay of the received (502) feedback signal. Furthermore, the method comprises adjusting (504) signals transmitted in the uplink according to the received (502) feedback signal, wherein compensation is made for the obtained (503) time delay value of the received (502) feedback signal. Further, a method and arrangement (800) in a network node (120) is presented.
