Claim:
1. A method for transmitting real-time video packets in a wireless communication system, the method comprising: receiving, by a first access point, fountain encoded packets from a gateway, the fountain encoded packets including at least a first set of fountain encoded packets corresponding to a video frame in a sequence of video frames; storing the first set of fountain encoded packets in a buffer of the first access point; transmitting, by the first access point, at least some fountain encoded packets in the first set of fountain encoded packets over a radio interface extending from the first access point to a user equipment (UE); receiving, by the first access point, an uplink broadcast message from the UE, the uplink broadcast message indicating that the video frame has been successfully decoded by the UE; and dropping remaining fountain encoded packets in the first set of fountain encoded packets from the buffer without sending the remaining fountain encoded packets over the radio interface upon receiving the uplink broadcast message indicating that the video frame has been successfully decoded by the UE.
