Cell densification is a typical means for capacity enhancement in a certain area. A flexible and dynamic way of cell densification can be provided via sectorization by Active Antenna Systems (AAS). By means of flexible beam forming capabilities, sectorization employs new sub-sector(s) reusing the same frequency band. The higher resource gain has to be paid off with more cell borders and cell edge users suffering from inter-sector interference. In this paper work, enhanced Intercell Interference Coordination (eICIC) technique is applied to coordinate the intra-site co-channel interference between the inner/outer sector in Vertical Sectorization (VS). Simulation results have shown that, eICIC brings significant system performance gain by improving the Signal to Interference plus Noise Ratio (SINR) experience of the users close to the inner/outer sector border regions; mainly, the severely affected regions of the outer sector.
