    • 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 a system frame number (SFN) 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.
    • 一种用于在移动通信系统中的基站和/或移动台中的下行链路和/或上行链路信道上发送控制数据的方法。 在一个实施例中,基站确定是否存在要向移动台发送的下行链路信道数据。 如果在预定时间段内没有要通过下行链路信道发送的数据,则基站驱动随机门控位置选择器以确定随机门控时隙位置,在所确定的时隙位置对控制数据进行门控,并关闭 在其他插槽位置控制数据。 随机位置选择器通过将接收信号的系统帧号(SFN)乘以特定整数来计算值x来确定选通时隙位置; 在用于生成下行链路信号的多个选通持续时间之前,从具有周期等于一帧的扰码开始点处的x码片距离的位置开始选择n个比特; 以及通过对所选择的n位执行模运算来确定对应的门控时隙组的门控时隙位置,其中模块操作是通过门控时隙组中的时隙数量。

    • A method and device for gating the transmission of dedicated control channels 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 transmit to a mobile station (base station) for predetermined period of time, the base station (mobile station) gates transmission of control information according to a predetermined pattern on a dedicated control channel, which channel is used for transmitting control information to the mobile station (base station). Control 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 Information (FBI) for information about a transmit diversity antenna system. In a downlink DPCCH, transmission of the TFCI, TPC and pilot symbol is transmitted discontinuously at every predetermined nth slot out of the total slots of a frame during gated transmission. Alternatively, transmission of the pilot symbol can be transmitted discontinuously at every predetermined nth slot and the TFCI and the TPC at every (n+1)th slot. In an uplink DPCCH, the TFCI, TPC, FBI and pilot symbol are transmitted discontinuously at a specific slot during gated transmission. In addition, the TPC for power control can be continuously transmitted for full rate power control when there is traffic data for transmission.
