Performance evaluation of different scheduling algorithms in LTE systems

Nowadays, LTE is widely used mobile communication technology. The development of mobile communications has never been faster. The main goal of mobile communications is to increase the data throughput and to ensure the best possible quality of communication between users, regardless of environment in which they are situated and type of data they share. In this paper, performance evaluation of different scheduling algorithms used in LTE systems is given. The following scheduling algorithms are considered: Round Robin, Proportional Fair, Best CQI, Resource Fair and MaxMin. Fractional Frequency Reuse (FFR) method, which represents a new way of resource allocation in LTE systems, is also evaluated in this paper. System performance was observed according to the following parameters: average throughput of user equipment, peak throughput of user equipment, edge throughput of user equipment and fairness in radio resources allocation. Vienna LTE System Level Simulator was used for conducting evaluation of LTE system.
