Abstract
A method of wireless communication using half duplex frequency division duplex (HD-FDD) comprises, at a wireless communications device, receiving downlink data during a plurality of downlink subframes and transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) on an uplink. The HARQ-ACK relates to downlink data received during at least two of the plurality of downlink subframes and the HARQ-ACK is transmitted during one uplink subframe.
