SIGNALING AND MANAGEMENT OF BROADCAST-MULTICAST WAVEFORM EMBEDDED IN A UNICAST WAVEFORM
Embodiments describe overlaying a broadcast multicast channel on top of a unicast network. Messages can be generated by protocols in a broadcast/multicast (BCMC) stack and tunneled through an IRTP of a serving access node. These messages can be transmitted on a BCMC channel and/or a unicast channel. Other messages can be generated by protocols in a unicast stack and tunneled to a B-IRTP of a BCMC Access node and transmitted on a BCMC channel to an access terminal.
