Abstract
A wireless receiving device and a method for receiving a transmission from a transmitting device following a broadcast transmission of a plurality of packets are provided. During the broadcast transmission, packets successfully received have been acknowledged and stored in a memory associated with the receiving device and unsuccessfully received packets have been negatively acknowledged. The method comprises receiving a retransmission of a packet from the transmitting device and sending, to the transmitting device, an acknowledge, ACK, message with respect to the received retransmitted packet. The method further comprises decoding the received retransmitted packet using stored previously successfully decoded packets, wherein if the received retransmitted packet is successfully decoded then the method comprises decoding stored previously partially decoded packets using the successfully decoded packet. The method also comprises storing the successfully decoded packet and/or the partially decoded packet.
