Abstract.-This paper addresses the use of Radio Environment Maps (REMs) to support interference management optimization in heterogeneous networks composed of cells of different sizes and including both cellular and non-cellular (e.g., Wi-Fi) technologies. After presenting a general architecture for including REM databases in different network entities, the paper analyzes the achievable benefits in relation to specific interference management techniques, including a discussion on practical considerations such as information exchange requirements, REM ownership and security aspects. Finally, several research directions derived from the proposed framework are identified.
The paper investigates the use of Radio Environment Maps (REMs) as a tool for Interference Management (IM) in two-tier cellular networks comprising macro-and femto-cells. The REMs are databases that provide, through different instances distributed over network elements, a variety of network-and user-related context information for improving IM and Radio Resource Management (RRM) procedures. In this context, the focus in this paper is to present the benefit of using REM information on practical power control schemes for the Femtocell downlink transmission in co-channel two-tier deployment.
