RADIO COMMUNICATIONS

Abstract

A radio transceiver device is provided. The radio transceiver device is arranged to transmit a data packet to a second radio transceiver device, the data packet comprising a header portion and a payload portion comprising a plurality of payload blocks, wherein each payload block comprises a data portion and an error detection portion. The device listens for an acknowledgement packet from the second radio transceiver device comprising an indication of which payload blocks were successfully received. If an acknowledgement packet is received which indicates that one or more payload blocks were not successfully received, the device transmits a further data packet to the second radio transceiver device comprising the one or more payload blocks that were not successfully received. If no acknowledgement packet is received, the device transmits an acknowledgment request packet to the second radio transceiver device.
