1. A method performed by a wireless receiving device for receiving a retransmission of a packet from a transmitting device following a broadcast transmission of a plurality of packets from the transmitting device, wherein packets successfully decoded during the broadcast transmission have been acknowledged by the wireless receiving device to the transmitting device and stored in a memory associated with the wireless receiving device and unsuccessfully decoded packets have been negatively acknowledged by the wireless receiving device to the transmitting device, the method comprising:
receiving the retransmission of the packet from the transmitting device;
sending, to the transmitting device, an acknowledge, ACK, message with respect to the received retransmitted packet;
decoding the received retransmitted packet using the stored previously successfully decoded packets;
based on a determination that the received retransmitted packet was successfully decoded, decoding stored previously partially decoded retransmitted packets if any using the successfully decoded packet, and storing the successfully decoded packet; and,
based on a determination that the received retransmitted packet was only partially successfully decoded, storing the partially decoded retransmitted packet.
