    • 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。
