Abstract  Abstract

A method for providing wireless communication of digital signals is provided with the digital signals being communicated between wireless subscriber units and a base station. The digital signals are communicated using at least one radio frequency (RF) channel via Code Division Multiple Access (CDMA) modulated radio signals defined by orthogonal codes. The method includes making available a plurality of orthogonal subchannels within each CDMA RF channel. Available orthogonal subchannels are allocated on an as-needed basis for subscriber units actively sending data. An idling mode connection is provided 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.
