Abstract
To meet the uplink performance requirements of improving spectrum efficiency and increasing the system capacity, inter-cell interference have must been mitigated effectively. This contribution described inter-cell interference mitigation with smart antenna based on user equipments (UE). And it discussed and compared smart antenna and omni antenna in LTE, focusing on the different of interference position, the ratios of inter-cell interference degradation and the system capacity. The analysis shows that inter-cell interference can degrade at least 66% and the system capacity should increase multiple times with the angle half the width of beam-forming from 30 to 100 degree. The more the UE which use the same frequency or PRB, the spectral efficiency will be reduced with the smart antenna’s angle unchanged.
