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.

摘要： Methods and systems for assigning time-division multiplexed (TDM) slots in a multi-channel TDM system are presented. Preferably, a radio access network (RAN) assigns forward link and reverse link transmissions between the RAN and one or more wireless communication devices (WCDs) to TDM slots on various wireless channels. When making these assignments, the RAN may take into account (i) the priority of data that the RAN queues for the WCDs, and (ii) the signal quality at which the WCDs can receive the various wireless channels.
