Abstract

See full text

A subscriber access unit includes a transceiver for providing wireless communication of digital signals. The digital signals are communicated to a base station using at least one radio frequency (RF) channel via Code Division Multiple Access (CDMA) modulated radio signals defined by orthogonal codes. Orthogonal subchannels are made available by the base station within each CDMA RF channel. A bandwidth manager is connected to the transceiver, and when the transceiver is actively sending data, at least one orthogonal subchannel is allocated by the base station on an as-needed basis. The number of orthogonal subchannels being allocated changes during a given session. The transceiver, when powered on but not actively sending data, provides an idling mode connection on a reverse link. The idling mode connection is based on an orthogonal subchannel shared with at least one other subscriber access unit, but utilizes different time slots of the shared orthogonal subchannel.
