Methods and arrangements in a wireless communication system

An arrangement in a user equipment for adjusting signals transmitted in the uplink to a network node, based on a feedback value received from the network node, the arrangement comprising:

• a transmitter, configured to transmit a signal, to be received by the network node,
• a receiver, configured to receive a feedback signal from the network node, providing feedback on the transmitted signal,
• a processing circuit, configured to obtain a value of a time delay of the received feedback signal, and to adjust signals transmitted in the uplink based on the value of the time delay of the feedback signal, wherein compensation is made for the obtained time delay value of the received feedback signal.

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.
