摘要：A method and device for gating the transmission of dedicated control channelsin a CDMA communication system is disclosed. In the device and method, if a base station(mobile station) determines whether there is no data to transmit to a mobile station(base station) for predetermined period of time, the base station (mobile station) gatestransmission of control information according to a predetermined pattern on a dedicatedcontrol channel, which is used for transmitting control information to the mobile station(base station). Control information transmitted from the base station to the mobilestation includes Transport Format Combination Indicator (TFCI), Transmit Power Control(TPC), and a pilot symbol. Control information transmitted from the mobile station to thebase station includes TFCI, TPC, a pilot symbol, and FeedBack Information (FBI) forinformation about a transmit diversity antenna system. In a downlink DPCCH,

transmission of the TFCI, TPC and pilot symbol of the predetermined n slots out of totalslots of frame can be transmitted discontinuously during gated transmission.

Alternatively, transmission of a pilot symbol of the predetermined nth slots and TFCI andTPC of (n+1)th slots can be transmitted discontinuously. In an uplink DPCCH,

transmission of all the TFCI, TPC, FBI and pilot symbol of a specific slot are transmitteddiscontinuously during gated transmission. In addition, transmission of TPC for powercontrol can be continuously transmitted for full rate power control when the traffic datais for transmission.
