摘要:
Methods and systems for performing hybrid automatic repeat request (ARQ) in conjunction with broadcast/multicast channels are presented. In particular, an access node may transmit a series of hybrid ARQ subpackets to one or more client nodes using a broadcast/multicast channel. Each of the subpackets may be derived from the same full packet. Upon receiving a subpacket, a client node may attempt to decode the full packet from the subpacket(s) derived from the full packet. If the client node fails to do so, the client node may transmit a negative acknowledgement to the access node. If the access node receives more than a threshold extent of negative acknowledgements, the access node may transmit a subsequent subpacket in the series on the broadcast/multicast channel.
