Abstract: PURPOSE: An apparatus and a method for gating data on a control channel in a CDMA communication system are provided to transmit on and off a DPCCH signal when there is no traffic data(user data or signaling message) to transmit over a data channel for a predefined time in a mobile communication system. CONSTITUTION: A method for transmitting control data on a downlink and/or uplink channel in a base station and/or mobile station in a mobile communication system. In one embodiment, the base station determines whether there is downlink channel data to transmit to a mobile station. If there is no data to be transmitted over the downlink channel for a predetermined time period, the base station drives a random gating position selector to determine a random gating slot position, gates on the control data at the determined slot position, and gates off the control data at other slot positions. The random position selector determines the gating slot position by calculating a value x by multiplying an SFN(System Frame Number) of a received signal by a specific integer; selecting n bits starting from a position which is at an x-chip distance from the start point of a scrambling code, which has a period equal to one frame, before a plurality of gating durations used in generating a downlink signal; and determining a gating slot position of a corresponding gating slot group by performing a modulo operation on the selected n bits, where the module operation is by the number of slots in a gating slot group.

Abstract: PURPOSE: An apparatus for performing synchronizations in an asynchronous code division multiple access(CDMA) communication system is provided to carry out transmissions of synchronous channels and synchronous captures within one period of a spread code in a CDMA communication system, and to perform communication with a synchronous method by using one synchronous channel in the asynchronous CDMA communication system, so as to reduce the number of times of the synchronous channel transmissions to minimize interferences of a forward link and to increase a system capacity. CONSTITUTION: A first synchronous channel is transmitted from a frame boundary or a one-period boundary of a spread code via an L1 chip. A second synchronous channel is transmitted in a location far from an L2 chip, from a time point when a transmission of the first synchronous channel is completed. A spread code used in the second synchronous channel and code groups including base stations correspond to each other by a predetermined regulation. If a terminal detects the second synchronous channel by using a specific spread code, the terminal recognizes a code group in which a corresponding base station is included. An interval 'L2' between the two synchronous channels is transmitted within a coherent time, to perform a coherent demodulation by transmitting the two synchronous channel with a same antenna. The interval 'L2' is assumed as one symbol. The 'L0' is capable of being attached right after the first synchronous channel, and is transmitted. If the terminal attempts a detection for the second synchronous channel, a time interval is permitted by being delayed to detect the second synchronous channel.
