Patent ID: 8625484

Claim:
A method for providing a multicast scheme, the method being implemented by a base station, the method comprising: receiving from a multicast server, at the base station, information about a fixed multicast rate; determining, by the base station and based at least in part upon the fixed multicast rate, a fixed modulation scheme, a fixed protocol data unit (PDU) payload size, and a fixed number of PDUs per downlink (DL) burst for transmission of multicast data to subscriber stations, the fixed modulation scheme, the fixed PDU payload size, and the fixed number of PDUs per DL burst remaining constant from one DL burst to a next DL burst and from one multicast frame to a next multicast frame; and allocating, by the base station, DL bursts to multicast frames, to deliver the multicast data to the subscriber stations via PDUs using the fixed modulation scheme, the fixed PDU payload size, and the fixed number of PDUs per DL burst.
