Abstract:
An UpLink (UL) scheduling method and apparatus considering a characteristic of a power amplifier in a mobile communication terminal are provided. The UL scheduling method includes calculating a packet transmission time, which minimizes energy consumed in packet transmission, by using a Direct Current (DC) voltage used in a power amplifier for signal amplification and by using nonlinear amplification efficiency; and scheduling UL data by using the calculated packet transmission time.
