Title: COMMUNICATION DEVICE, INFRASTRUCTURE EQUIPMENT AND METHODS
Abstract:
A communications device is configured to receive data from a wireless communications network. The communications device comprises receiver circuitry, transmitter circuitry and controller circuitry controlling the transmitter circuitry and the receiver 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 packets encoded with an error correction code and the transmitter circuitry transmits a feedback signal depending on whether each of the data encoded packets is estimated as having been decoded successfully by the receiver circuitry. The controller circuitry is configured to evaluate a quality measure of each encoded data packet and in response to the evaluated quality measure to transmit an early indication of the feedback signal to the wireless communications network, before the encoded data packet has been decoded by the error correction decoder. As a result a transmission time of an encoded data packet can be reduced and/or a reduction in communications resource usage can be achieved due to a timely stopped repeated transmission.
