    • 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.

    • PURPOSE: Disclosed is a communication device capable of accurately detecting the transmission delay of each mobile station without exerting influence upon transmission capacity and the number of stored channels. CONSTITUTION: A receiving part(602) receives a signal obtained by multiplexing the signals of respective channels in the same frequency band through an antenna(601) A separation part(603) separates a part to be used for the calculation of a correlation value in the received signal.

When there is no propagation delay, a comparing/line estimation part(606) circulates individual delay profiles so that sections in which paths of channels to be detected appear coincide with each other and detects paths approximately coinciding with each other in respective circulated delay profiles.
