Performance Evaluation for Resource Allocation Algorithms in CoMP Systems

Abstract

The International Telecommunications Union estab- lished through the International Mobile Telecommunications-Advanced a set of requirements for high performance 4rd Generation communication systems and, with the aim of meeting such requirements, 3rd Generation Partnership Project Long Term Evolution (LTE) is considering a set of enhancements, referred to as LTE-Advanced. In LTE-Advanced context, Coordinated Multi-Point (CoMP) communication appears as a promissing technology to boost system throughput and to allow for an efficient Resource Allocation (RA). In this paper, we study RA algorithms that exploit coordination in the Downlink (DL) of CoMP systems to implement adaptive frequency reuse and so improve system throughput. We show through system-level analyzes that quite high throughput gains are achieved through intelligent RA.
