Patent attributes
A communications system including a transmitting device having plural transmit antennas and a receiving device having plural receive antennas. When it is determined that an error has occurred in a first data transmission attempt in which data signals are transmitted from a first selection of transmit antennas for receipt at a second selection of receive antennas, a second data transmission attempt is performed in which the data signals are re-transmitted from a third selection of transmit antennas for receipt at a fourth selection of receive antennas. Before the second transmission attempt, a reconfiguration operation is performed to ensure the channel response between the transmit and receive antennas selected for the first transmission attempt is different to the channel response between the transmit and receive antennas selected for the second transmission attempt. Data is then recovered at the receiving device using information from the first and second transmission attempts.
