Classification: H04W

Abstract:
A base station in a radio communication system capable of receiving reverse channel data using two over the air protocols, comprising:a transmitter and modulator for forward channel transmissions in at least a first over the air protocol;a multi-mode base receiver capable of receiving data on a reverse channel using multiple over the air protocols including the first protocol and at least a second over the air protocol;a timing source for the second over the air protocol derived from a remote controller for the second over the air protocol;a processor programmed to:decode timing information from the timing source for the second over the air protocol allowing the multi-mode base receiver to provide a busy indicator to the transmitter and modulator corresponding to the first over the air protocol;inhibit the reverse channel of the first over the air protocol during a period set by the busy indicator;configure the reverse channel to receive data in the second over the air protocol at the multi-mode base receiver capable of receiving data on a reverse channel in one of a plurality of protocols;demodulate and decode the reverse channel in the second over the air protocol for a period indicated by the timing information; andconfigure the reverse channel to receive data in the first over the air protocol after the time indicated by the timing information.
