Abstract:
1. 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 (RF) channel via Code Division Multiple Access (CDMA) modulated radio signals defined by orthogonal codes, the method comprising: making available a plurality of orthogonal subchannels within each CDMA RF channel, each orthogonal subchannel having a data rate less than a nominal data rate of the digital signals; allocating available orthogonal subchannels on an as-needed basis for subscriber units actively sending data, with the number of orthogonal subchannels being allocated changing during a given session; and providing an idling mode connection on a reverse link for subscriber units which are powered on, but not actively sending data, by assigning a shared orthogonal subchannel to at least two different subscriber units, but utilizing different time slots of the shared orthogonal subchannel.
