Abstract

A method controlling wireless communication of a data block from a terminal device to a base station includes: making a first uplink transmission for the data block in association with a first retransmission protocol process and obtaining a corresponding first acknowledgement indication indicating whether the data block has been successfully communicated to the base station; making a second uplink transmission for the data block in association with a second retransmission protocol process and obtaining a corresponding second acknowledgement indication, the second transmission initiated before the first acknowledgement indication is obtained; and determining whether to avoid scheduling retransmission of data for the data block in association with the first retransmission protocol process based on the first and second responses, avoiding data retransmission in association with the first retransmission protocol process if either the first or second acknowledgement indications indicate the data block has been successfully communicated to the base station.
