Abstract
A base station and a mobile station for a CDMA communication system intermittently exchange data on a power control group unit or time slot unit in a control hold state to minimize interference. To this end, during channel transmission, the system intermittently transmits a reverse pilot channel signal in the control hold state; upon activation of a reverse dedicated control channel, transmits a normal pilot channel signal which is first generated after activation of the reverse dedicated control channel; and then transmits the reverse dedicated control channel.
