Abstract
The 4th generation mobile communication systems, LTE-A, have explosive subscriber increase and the demand of supporting backward capability for LTE users. Therefore, LTE- A systems need more careful allocation of communication resources to provide enough data rate from BS for subscriber devices. This thesis deals with scheduling for efficient resource distribution according to whether the subscriber can use carrier aggregation. We propose the scheduling with a max-min optimization tool to improve the performance of subscribers as distinct cell coverage areas are served with different frequency bands. The simulation results show performance improvement of the subscribers both for LTE and LTE-A. ⓒ 2016 DGIST
