Abstract
The present invention provides methods and apparatus for transmitting of multicast data over a wireless channel. At least one wireless terminal requests a multicast service corresponding to at least one requested layer. A wireless infrastructure comprising a base station and a node determines a data rate that the at least one wireless terminal can reliably receive and correspondingly configures a multicast session for at least one layer. The node utilizes measurements provided by the wireless terminal. The node through the base station signals the wireless terminal about a link-level multicast address corresponding to a time slot for which the wireless terminal shall process packets.
