Summary:This paper proposed a relay sharing and soft frequency reuse based (RSSFR) frequency planning scheme, which reaches high data rates while using the precious frequency resource efficiently, system performance is analysed and evaluated as well. System performance is enhanced in four aspects: 1) Co-channel interference is reduced significantly, which broadens the area of high achievable data rates in each cell. 2) Base stations (BSs) communicate with fixed relay stations through narrow beam antennas, which boosts the resource efficiency without bringing much interference to mobile stations (MSs). 3) The relay sharing strategy can not only bring down network cost, but also provide a better coverage to cell edge users. 4) Soft frequency reuse on shared relay increases the frequency resource efficiency further. Simulation results show that, a better tradeoff between cell throughput and frequency resource efficiency is achieved in RSSFR.
