Abstract

A technique of processing an Automatic Repeat Request (ARQ) transmission is disclosed. As to a method aspect of the technique the method (200) comprises the steps of requesting (210) a retransmission of a transport block; receiving (220) the retransmission of the transport block; and detecting (230) modulation symbols. The retransmission is requested in response to an error detecting code indicating an error in the transport block as received in at least one previous transmission. The modulation symbols are detected based on at least a part of the received retransmission and information from the at least one previous transmission. At least in some embodiments a detection rate is thus improved.
