Abstract  Abstract

The present invention provides a service for CDMA wireless communication in which a plurality of assignable subchannels are defined by assigning different code phases of a given long pseudorandom noise (PN) code for each subchannel in the reverse link. Its about an optional overlay. The immediate bandwidth requirements of each on-line subscriber unit can be met by dynamically allocating one or several subchannels or not assigning any channels according to the needs of each network layer connection. Can be. This system allows a relatively large number of times between the subscriber unit and the base station on the reverse link for long periods of idle time, such as when a computer connected to the subscriber unit is powered on but is currently not actively transmitting or receiving data. It effectively provides virtual physical access. The maintenance subchannel allows the base station and the subscriber unit to maintain phase and time synchronization. This makes it possible to quickly acquire additional subchannels by allocating new code phase subchannels as needed. Preferably, the code phase of the new channel is assigned according to a predetermined code phase relation for the code phase of the corresponding sustain subchannel.
