Currently, femtocells and macrocells are seen as isolated networks, competing for the resources available in the common spectrum band, at the cost of injecting interference to the whole system. FREEDOM project will face key technical and industrial concerns about the foreseen mid-term massive deployment of femtocells by adopting a new approach based on cooperative/coordination paradigms, enabled by the limited ISP backhaul link. The project will not disregard the approach of isolated networks because it is met when there is not enough backhaul link connecting the femtocells and macrocell. In order to guarantee a strong focus and efficiency, FREEDOM will focus on: advanced interference-aware cooperative PHY techniques; improvement of the control plane procedures for seamless connectivity and system-level and hardware feasibility evaluation of the proposed femto-based network architecture.
The purpose of this document is twofold: first evaluating the interference management
algorithms developed in WP3 at system le
vel, and second, studying the tradeoffs and
complementarities in network deployments based either on relay stations or on femto access points.
