METHOD AND ARRANGEMENT IN A COMMUNICATION SYSTEM

摘要

590607 Disclosed is a method in a terminal (120) for providing acknowledgement information or non-acknowledgement information "ACK/NAK" to a base station (110) concerning the reception status of data packets received in a subframe from the base station (100). ACK/NAK is generated and sent to the base station (110) and a scrambling code is selected based on the total number of received subframes. The generated ACK/NAK is then scrambled with the selected scrambling code, and sent to the base station (110). The number of subframes received from the base station (110) is then counted.
