Network Coverage Enhancement for Mobile Communication SystemsThe coverage of mobile cellular networks is non-uniform (even in urban areas) due to inter-cell interference and signal fading. To address this problem, this research proposal aims to investigate novel and practical methods to provide uniform network coverage. One such method that is aimed to be investigated particularly is 鈥淐ell Sweeping鈥 in which the sectors of a base station (BS) are swept electrically over a part or entire 360掳 in the azimuth plane (and / or elevation plane). The sweeping cells allow the users to be served on the antenna boresight beam with enhanced gain and hence improves the network cell-edge performance significantly.

鈥擡nsuring robust and uniform network coverage is crucial for mobile network operators, particularly at the cell edges, where interference remains a persistent challenge. Traditional solutions such as network densification are complex, costly, and prone to increased interference. This paper presents the performance of recently proposed Cell-Sweeping base stations deployment in a typical 4G LTE network with Single User-Multiple Input Multiple Output (SU-MIMO) operation, use of higher-order modulation schemes, i.e. 256-Quadrature Amplitude Modulation (256-QAM), as well as using 3D antenna radiation patterns. By dynamically sweeping the antenna radiation patterns, cell-sweeping aims to significantly enhance the cell-edge performance while at the same time also harmonises the distribution of throughput in the whole cell. System-level simulations conducted using the 3rd Generation Partnership Project (3GPP) configurations reveal significant performance gain of cell-sweeping of up to 147% improvement in cell-edge throughput observed under open-loop spatial multiplexing, i.e. Transmission Mode 3 (TM3) in 3GPP LTE compared to conventional (i.e. non-cell sweeping) cellular network deployment. The results demonstrate that integrating cell-sweeping with advanced modulation and MIMO configurations is feasible and significantly improves Signal-to-Interference-plus-Noise Ratio (SINR), throughput, and Channel Quality Indicators (CQI) distribution, particularly in dense urban environments. These findings highlight the potential of cell-sweeping as an effective and simpler deployment strategy for future radio access networks.
