Abstract :
This work presents a low-cost, low complexity deployment concept for a relay-based cellular broadband network. The concept is based on a combination of a multi-antenna OFDMA base station (BS) and simple, single-antenna OFDMA relay nodes (RN) and user terminals (UT). The concept further encompasses a partitioning of the available radio resources in the frequency domain to control interference within and between relay enhanced cells (REC). The performance of the proposed system in a suburban cellular setup is evaluated by means of stochastic, event-driven simulation and a comparison against a pure BS-only scenario is made.
