Sommaire du projet

With increasing demands for higher capacity and peak throughput in 4G wireless networks such as LTE, a number of feature enhancements are being considered to address these demands. Principal among these for LTE-Advanced is the use of Coordinated Multi-Point (CoMP) operation. This is a highly active area of investigation with an aim to improve aggregate cell throughput, cell edge user throughput as well as coverage gaps at the cell edge. The framework of CoMP being currently defined in 3GPP for LTE-Advanced encompasses a number of approaches including coordinated scheduling, coordinated beamforming, joint transmission and reception, as well as dynamic point selection. The processing and control for any of these CoMP implementations can be coordinated either centrally or through use of a distributed processing architecture. Distributed processing architectures for CoMP have the potential advantages of lower latency and reduced complexity with a possible tradeoff in performance. The purpose of the proposed research is to evaluate the performance of distributed CoMP architectures by exploiting known frameworks and efficiencies for distributed processing. This study will investigate and propose an evaluation framework and methodology for distributed CoMP processing, propose candidate distributed control algorithms and evaluate the performance of the CoMP solutions based on complexity and latency metrics.
