Abstract: PROBLEM TO BE SOLVED: To provide a method for transferring data from a base station to a mobile terminal at a high-speed by using an additional broadband communication channel that assists communication served by a link in a reverse direction (from mobile station to base station) and in a forward direction (from base station to mobile station) employed by a cellular communication system or a PCS communication system. SOLUTION: A standard forward direction and reverse direction link is used for a control channel for data transfer on the additional forward broadband channel and for voice and low speed data traffic. Furthermore, communication executed on the narrow band forward link channel is transmitted on the additional broadband forward channel to eliminate need for the narrow band forward link channel. A mobile terminal has a conventional FDD(frequency division duplex) section 210 and an additional section 220. The additional section 220 receives data communicated through the broadband additional channel.

Abstract: High speed data transfer from a base station to a mobile terminal is provide d using an additional wide band communication channel that supplements the communicatio ns provided by the reverse (mobile to base station) and forward (base station to mobile) links used in cellular or PCS communications systems. In one embodiment, the standard forward and reverse links are used as control channels for data transfers over the additional or adjunct forward wide band channel. In another embodiment, the communications carried out over the narr ow band forward link channel are sent over the adjunct wide band forward channel thereby eliminating the need for a narrow band forward link channel.
