摘要：A communications device is configured to receive data from a wirelesscommunications network. The communications device comprises receiver circuitry,transmitter circuitry and controller circuitry controlling the transmitter circuitry and thereceiver circuitry to receive the data in accordance with an automatic repeat request,ARQ, type protocol in which the data is received as a plurality of encoded data packetsencoded with an error correction code and the transmitter circuitry transmits a feedbacksignal depending on whether each of the data encoded packets is estimated as havingbeen decoded successfully by the receiver circuitry. The controller circuitry is configuredto evaluate a quality measure of each encoded data packet and in response to theevaluated quality measure to transmit an early indication of the feedback signal to thewireless communications network, before the encoded data packet has been decoded bythe error correction decoder. As a result a transmission time of an encoded data packetcan be reduced and/or a reduction in communications resource usage can be achieveddue to a timely stopped repeated transmission.
