1. An infrastructure equipment configured to form part of a radio access network of a wireless communications network for receiving data from a communications devices co-operating with the wireless communications network, the infrastructure equipment comprising
receiver circuitry configured to receive signals transmitted, by the communications device, via a wireless access interface formed by the infrastructure equipment,
transmitter circuitry configured to transmit signals via the wireless access to the communications device, and
controller circuitry configured to control the transmitter circuitry and the receiver circuitry to:
receive the data represented as signals from the wireless access interface in accordance with an automatic repeat request, ARQ, type protocol in which the data is received as one or more encoded data packets, the encoded data packets having been encoded with an error correction code and the transmitter circuitry is configured to transmit a feedback signal depending on whether each of the encoded data packets is estimated as having been decoded successfully or unsuccessfully by the receiver circuitry in accordance with the ARQ type protocol, and the encoded data packet is transmitted using a plurality of Orthogonal Frequency Division Multiplexed, OFDM, symbols, each of which is formed by a plurality of modulation symbols carried by a corresponding plurality of sub-carrier signals of the wireless access interface and each OFDM symbol carries encoded data symbols of the encoded data packet, the plurality of OFDM symbols being transmitted repeatedly, and the controller circuitry is configured in combination with the receiver circuitry;
combine information received from an encoded data packet from one or more of the repeatedly transmitted OFDM symbols of the encoded data packet;
determine from the combination of the information received from the repeatedly transmitted OFDM symbols whether the data carried by the encoded data packet can be successfully decoded; and
depending on whether the data carried by each encoded data packet can be successfully decoded or not in accordance with the ARQ protocol, control the transmitter circuitry to transmit the feedback signal.
