Methods for delivery of multicast packets in a wireless communication system are disclosed. The methods comprise transmitting a contention free period initiation signal from an access point to the station, transmitting broadcast packets from the access point to the station, transmitting multicast packets from the access point to the station and holding the multicast packets in storage after the transmission, transmitting a contention free period end signal from the access point to the station, determining if a negative acknowledgement message has been received, retransmitting the multicast packets in response to receiving a negative acknowledgment message, and eliminating the multicast packets at a next beacon interval.
