Active Antenna System (AAS) is an advanced antenna technology that features the ability of advanced beamforming techniques to provide a great flexibility in cellular network deployment which enables improvements in network capacity and coverage. Conventionally, network dimensioning is done based on busy hour traffic leading to cost-intensive overdimensioning for most of the time via deploying additional macro and small cells. In AAS, however, varying traffic concentrations can be flexibly handled by dynamic cell densification, e.g. by splitting a sector into smaller "sub-sectors". Vertical sectorization is a well-known approach where a conventional sector is split vertically in to two, inner and outer sectors, resulting in 3x2 sectors per site for AAS-based tri-sectorized site. In this paper work, an alternative vertical sectorization deployment configuration is presented where the inner sectors build a so called super-cell resulting from transmitting the same cell information in all inner sectors. Investigation results show that the super-cell configuration can mitigate unwanted back and side lobe effects in close proximity of the site and, therefore, provides a significant gain for users in this coverage area.
