Abstract
In a radio access network, multicast packets are delivered each identified by a multicast network layer address representing a multicast group of access terminals. The multicast packets are delivered in one or more air link frames using a common control channel that is shared among access terminals in a sector. Each airlink frame carries a multicast air link address that identifies the multicast group of terminals.
