APPARATUS AND METHOD FOR GATED TRANSMISSION IN A CDMA COMMUNICATION SYSTEM

摘要

A method and device for gating the transmission of dedicated control channel s in a CDMA communication system is disclosed. In the device and method, if a base station (mobile station) determines whether there is no data to transmi t to a mobile station (base station) for predetermined period of time, the bas e station (mobile station) gates transmission of control information according to a predetermined pattern on a dedicated control channel, which is used for transmitting control information to the mobile station (base station). Contr ol information transmitted from the base station to the mobile station includes Transport Format Combination Indicator (TFCI), Transmit Power Control (TPC), and a pilot symbol. Control information transmitted from the mobile station to the base station includes TFCI, TPC, a pilot symbol, and FeedBack Informatio n (FBI) for information about a transmit diversity antenna system. In a downli nk DPCCH, transmission of the TFCI, TPC and pilot symbol of the predetermined n slots out of total slots of frame can be transmitted discontinuously during gated transmission. Alternatively, transmission of a pilot symbol of the predetermined nth slots and TFCI and TPC of (n+1)th slots can be transmitted discontinuously. In an uplink DPCCH, transmission of all the TFCI, TPC, FBIa nd pilot symbol of a specific slot are transmitted discontinuously during gated transmission. In addition, transmission of TPC for power control can b e continuously transmitted for full rate power control when the traffic data i s for transmission.
