Link and System Level Simulation of Downlink LTE

Abstract—3GPP LTE is the evolution of the UMTS which will make possible to deliver next generation high quality multimedia services according to the users ’ expectations. Since Radio Resource Management (RRM) has been recognized as a key point to successfully accomplish this target, the performance evaluation of a multi-cell resource allocation scheme applied to LTE downlink (DL) is presented in this paper. A semi-distributed and a fully-distributed RRM framework are compared on the basis of the obtained system throughput. Detailed link level simulations have also been carried out to properly back up the system level results. I
