Abstract
A system for sending multimedia information from at least one base station to one or more mobile stations via at least one wireless communication link includes at least one multimedia source for generating the multimedia information. At least one processor is coupled to the multimedia source for generating a number of data streams derived from the multimedia information on a media control access (MAC) layer. At least one data channel modulator is coupled to the processor for mapping the data streams into a number of data packets on a forward packet data channel between the base station and the mobile station, using a physical layer signaling based on a code-division multiple access (CDMA) or orthogonal frequency division modulation (OFDM) technology.
