摘要： Apparatus and method for guaranteeing a Quality of Service (QoS) traffic rate in a mobile communication system are provided. The scheduling method for guaranteeing a QOS traffic rate in a mobile communication system includes calculating a total sum of traffic rates based on a channel change and a total sum of sustained traffic rates; calculating a weighted traffic rate using the traffic rate based on the channel change and the sustained traffic rate when the sustained traffic rate does not meet the QoS traffic rate; and determining a service priority using the weighted traffic rate. Therefore, the minimum reserved traffic rate and the maximum sustained traffic rate can be assured.

The LCD includes a timing controller generating first and second output enable signals, first and second level shifters respectively generating first and second gate clock pulses and inverted clock pulses, and first and second gate drivers respectively generating first and second gate driving signals. A precharge time of the first gate driving signals is controlled by the pulse width of the first output enable signal and a precharge time of the second gate driving signals is controlled by the pulse width of the second output enable signal.
