CHANNEL COMMUNICATION DEVICE AND METHOD FOR CDMA COMMUNICATION SYSTEM

摘要

A CDMA communication system transmitting/receiving control information during a voice and/or data communication service by using a dedicated control channel. A message frame length for the control information is variable according to an amount of the control information. The CDMA communication system includes a base station device and a terminal device. The base station device has a forward pilot channel generator for generating a pilot signal, a forward dedicated control channel generator for generating a control message for a forward dedicated control channel, a forward fundamental channel generator for generating a voice signal, and a forward supplemental channel generator for generating packet data. The terminal device has a terminal device including, a reverse dedicated control channel generator for generating a control message for a reverse dedicated control channel, a reverse pilot channel generator for generating a pilot signal by adding a power control signal to the pilot signal, a reverse fundamental channel generator for generating a voice signal, and a reverse supplemental channel generator for generating packet data.
