<P>PROBLEM TO BE SOLVED: To achieve fast acquisition of an additional subchannel on as needed basis by allocating a new code phase subchannel. <P>SOLUTION: There is provided a service option overlay for a CDMA wireless communication system in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The necessary instantaneous bandwidth of each on-line subscriber unit are then adapted by dynamically allocating on none, one, or multiple subchannels based on each network layer connection an as needed. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism. <P>COPYRIGHT: (C)2012,JPO&INPIT |
