Abstract
A method (800) for a communications system (100, 300), with a sender (110), which transmits data as packets to a receiver (120). The receiver transmits (805) quality values to the sender representing the reception quality of packets received with errors. The receiver stores (810) information regarding a number of received data packets, and there is a relay transceiver (130) between the sender and the receiver. Both the relay transceiver and the sender can encode (820) data packets into composite packets, to transmit (825) composite packets to the receiver. Said stored information in the receiver (120) comprises the data in correctly received packets and information regarding the reception quality of packets received with errors and the data of those packets, and the stored information is used by the receiver to decode (835) composite packets, thereby extracting the data in the packets of the composite pockets.

17. A receiving transceiver, comprising:
-
a receiver operative to receive transmissions sent from a relay transceiver; a transmitter operative to send to the relay transceiver quality values representative of the reception quality of data packets received with errors; memory operative to store data packets and information about data packets received with errors; and a controller operative to decode data packets from one or more composite packets, each composite packet including a data packet the receiving transceiver has received with errors and a data packet the receiving transceiver has received without errors. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A method by a receiving transceiver of receiving data packets transmitted by a relay transceiver, comprising:
-
receiving one or more data packets; attempting to decode the data packets; temporarily storing data packets and information about data packets received with errors; transmitting to the relay transceiver quality values representative of the reception quality of data packets received with errors; receiving from the relay transceiver one or more composite packets, each composite packet including a data packet previously received with errors and a data packet previously received without errors; and decoding the data packet previously received with errors using the composite packet and the stored data packets and information. - View Dependent Claims (27, 28, 29, 30, 31, 32)
