Abstract
Aspects of multicast retry in a communication network includes a terminal device serving as an originator station device within a multicast group configured to provide transmission of one or more protocol data units via a network utilizing a multicast address. Subsequent to transmission of the one or more protocol data units, the terminal device may receive an acknowledgment protocol data unit via one of many destination terminal devices configured to serve as a responder. The received acknowledgment protocol data unit provides a basis to determine whether the transmitted protocol data units were successfully received by one or more destination terminal devices. One or more of the protocol data units may be retransmitted based on the determination. Also, following retransmission, a supplemental acknowledgment protocol data unit may be provided via a destination terminal device of the destination terminal devices exclusive of the responder destination terminal device.
