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 includes transmitting a signal, to be received by the network node. A feedback signal is received from the network node, providing feedback on the transmitted signal. A value of a time delay of the received feedback signal is obtained. Signals transmitted in the uplink are adjusted according to the received feedback signal to compensate for the obtained time delay value of the received feedback signal. Related methods and arrangements in a network node are presented.

29. A method 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 comprising:
-
transmitting a signal, to be received by the network node, receiving a feedback signal from the network node that provides feedback on the transmitted signal, obtaining a value of a time delay of the received feedback signal, and adjusting signals transmitted in the uplink based on the value of the time delay of the feedback signal to compensate for the obtained time delay value of the received feedback signal. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

46. A method in a network node for providing a value of a time delay of a feedback signal transmitted to a user equipment for adjustment of signals transmitted in the uplink by the user equipment, based on a feedback value provided by the network node, the method comprises:
-
determining that the user equipment is to adjust signals transmitted in the uplink, based on the value of the time delay of the feedback signal, and transmitting a request to be received by the user equipment, triggering the user equipment to determine the time delay value of the feedback signal. - View Dependent Claims (47)
