Abstract  Abstract

A service option overlay for a CDMA wireless communication system that defines a plurality of assigned subchannels on the reverse link by assigning each subchannel a predetermined long pseudo noise (PN) code of a different code phase. is there. The required instantaneous bandwidth of each online subscriber device is adapted by dynamically assigning (or not assigning) one or more sub-channels as needed based on each network layer connection. The system uses a relatively large number of virtual physical connections between the subscriber unit and the base station on the reverse link during a long idle time when the computer connected to the subscriber unit is powered on without data transmission / reception operations. To provide efficient. These maintenance subchannels allow the base station and the subscriber unit to maintain phase and time synchronization. Thereby, by allocating the new code phase sub-channel, it is possible to obtain an additional sub-channel at high speed as needed.
