The demand for higher speed of wireless communication has been increased dramatically during the past few decades due to the popularity of smart phones, Wi-Fi, and other wireless applications. To improve the transmission rate and reduce the complexity of the system architecture, a long term evolution (LTE) has been launched by 3GPP for 3G communications. Under the multiple-carrier scenarios, scheduling algorithm in MAC layer of LTE system plays an important role to the system performance. In this study, several downlink scheduling algorithms are proposed and analyzed, and their performances are compared through system level simulations. It is observed that the proposed scheduling algorithm shows better performance in terms of Quality of Service (QoS) and computational complexity.
