Patent ID: 8730960

Claim:
An apparatus, comprising: a transmitter for communicating on one or more channels; a receiver; a controller coupled with the transmitter and receiver; wherein the controller is operable to transmit channel reservation data via the transmitter to reserve a first channel for a transmission opportunity; wherein the controller is operable to transmit multicast data during the transmission opportunity; wherein the controller is operable to transmit a block acknowledgement request for the multicast data during the transmission opportunity; wherein the controller is operable to wait to receive a block acknowledgement for the multicast data via the receiver during the transmission opportunity; wherein the controller selectively changes a data transmission rate for the block acknowledgment request to a new data transmission rate responsive to not receiving an expected block acknowledgement; wherein the controller selectively retries the block acknowledgment request at the new data transmission rate; and wherein the controller selectively resends unacknowledged multicast data during the transmission opportunity.
