METHODS AND ARRANGEMENTS IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method 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 comprisingtransmitting (501) a signal, to be received by the network node (120),receiving (502) a feedback signal from the network node (120), providing feedback on the transmitted (501) signal,obtaining (503) a value of a time delay of the received (502) feedback signal, andadjusting (504) signals transmitted in the uplink based on the value of the time delay of the feedback signal, wherein compensation is made for the obtained (503) time delay value of the received (502) feedback signal.

Abstract
Method and arrangement in a user equipment for adjusting signals transmitted in uplink to a network node, based on a feedback value received from the network node. The method comprises transmitting a signal, to be received by the network node. Further, the method comprises receiving a feedback signal from the network node, providing feedback on the transmitted signal. In addition, the method comprises obtaining a value of a time delay of the received feedback signal. Furthermore, the method comprises adjusting signals transmitted in the uplink according to the received feedback signal, wherein compensation is made for the obtained time delay value of the received feedback signal.
