Claim:
1. A communication node arranged to communicate with another communication node using communications resources that are arranged in subframes, the communication node comprising: a controller configured to generate and output a control message for the other communication node, the control message allocating communications resources within a plurality of subframes over which the communication node will transmit at least one codeword in each subframe for the other communication node; and a transceiver configured to transmit the codewords to the other communication node using the allocated communications resources within the plurality of subframes, wherein the transceiver is further configured to receive, from the other communication node, ACK/NACK feedback for each codeword indicating acknowledgment of receipt or non-receipt of the codeword, wherein the transceiver is further configured to receive, during a subframe, aggregated ACK/NACK feedback from the other communication node indicating acknowledgment of receipt or non-receipt of each of a plurality of codewords transmitted by the communication node in different subframes, and is further configured to process the aggregated ACK/NACK feedback to control the controller so that any codewords that were not received are scheduled for retransmission to the other communication node, and wherein the aggregated ACK/NACK feedback comprises an order of subframes concerned with Hybrid Acknowledge Repeat Request (HARQ) processes.
