Abstract
Wireless communications may benefit from a method, an arrangement, and a detector for detecting HARQ-ACK information. According to embodiments of the present invention, the method comprises extracting a HARQ-ACK symbol sequence in data transmitted from a user equipment. The method also comprises generating a plurality of candidate HARQ-ACK symbol sequences. The method further comprises calculating a degree of similarity between each of the plurality of candidate HARQ-ACK symbol sequences and the extracted HARQ-ACK symbol sequence to obtain a plurality of degrees of similarity. The method additionally comprises comparing an extremum of the plurality of degrees of similarity with a predetermined threshold. Furthermore, the method comprises determining, based upon the comparing, whether the HARQ-ACK information has been transmitted from the user equipment.
