Abstract
Method and arrangement (600) in a terminal (120) for receiving data packets from a base station (110) and providing feedback to the base station. The feedback concerns the reception status of the received data packets and may comprise an ACK/NAK. The method comprises receiving and decoding data packets from the base station in a subframe. It is further established whether any data packet within the received subframe is not correctly received and detected whether any subframe, expected to be received, has been missed. Further, acknowledgement information ACK/NAK is generated (501), a scrambling code selected with which the ACK/NAK is scrambled (505). The scrambled ACK/NAK is then sent to the base station, concerning the reception status of the data packets within the received subframes.
