A hybrid scheme of femtocell and distributed antenna system (DAS) is proposed that utilizes a subband dedicatedly assigned to each of multiple femtocells for system capacity gain and a subband shared for DAS simulcasting for cell-edge interference reduction. This paper presents a fundamental downlink performance evaluation and analysis of the in-building wireless system. Proportional fair (PF) scheduling is used for the user assignment, and the throughput performance is evaluated under various conditions. Simulation results show that the system can provide remarkable gains in cell-edge throughput while maintaining high average throughput, particularly in situations where high signal quality is available at the subband shared for the DAS and the system is of high upper bound of spectrum efficiency.
