英文摘要: This project studies the new access theory and technology in small cell systems.To evaluate how the random distributed topology, unbalanced transmit powers of different base stations and the spectrum spatial reuse in small cell systems affect the system capacity, the relationship between the parameters (number of base stations, distribution of the base stations, load balance, interference and so on) and the system capacity is ananlyzed. Based on the analysis,the optimization and game theories are applied to design the load balance, interference coordination and energy saving technology, which can improve the spectrum efficiency and energy efficiency of the small cell systems.
