Abstract:
A method for providing wireless communication of digital signals, the digital signals being communicated between a plurality of wireless subscriber units and a base station, the digital signals being communicated using at least one radio frequency channel via Code Division Multiple Access (CDMA) modulated radio signals, the digital signals also having a given nominal data rate, the method comprising the steps of:a) making available a plurality of subchannels within each CDMA radio channel, wherein a data rate of each subchannel is much less than the nominal data rate of the digital signals; b) allocating available subchannels on an as-needed basis, wherein the number of subchannels allocated is variable during the duration of a given session; and c) on a reverse link, providing an idling mode connection for subscriber units which are powered on, but not presently actively sending data, wherein the idling mode connection is operable to enable subchannels to be reallocated without reestablishing a bit synchronization with the base station.
