APPARATUS AND METHOD FOR UPLINK SCHEDULING CONSIDERING POWER AMPLIFIER IN MOBILE COMMUNICATION TERMINAL

摘要

An uplink scheduling method for considering a power amplifier in a mobile communication terminal and a device therefor are provided to calculate packet transmission time having maximum energy efficiency by considering correlation between energy and transmission time of information bits, and to perform uplink scheduling by using the calculated time, thereby reducing energy consumption. A transmission time calculator(301) calculates packet transmission time having minimum energy consumed in case of packet transmission by using nonlinear amplification efficiency and a DC(Direct Current) voltage used for signal amplification in a power amplifier. A scheduling unit(303) schedules uplink data by using the calculated packet transmission time. The transmission time calculator calculates transmission time of one information bit and channel capacity for each of packet transmission power, and calculates transmission energy of the one information bit by using the calculated time.
