Improvement of inter-cell spectrum efficiency is a valuable research topic in mobile communication system, which impact cell edge user experience especially. According to current research results, three methods to deal with inter-cell interference to improve inter-cell spectrum efficiency, including inter-cell interference randomization, inter-cell interference cancellation and inter-cell interference co-ordination. This paper analyses three important inter-cell spectrum efficiency improvement technologies: soft frequency reuse (SFR), uplink power control, downlink coordinated multi-point transmission/reception (CoMP), and relative research progress.
