Network Coverage Enhancement for 6G Communication System
ICS / School of Electronics and Computer Science
The 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 “Cell Sweeping” in which the sectors of a base station (BS) are swept electrically over a part or entire
360° 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. The research will investigate the merits of cell-sweeping technology in the radio access networks (RANs) of future 6G communication systems in comparison with other state of the art coverage enhancement techniques such as RIS (which also provide dynamic radiation footprint) and will focus on:
- A rigorous theoretical analysis to determine the fundamental coverage / capacity limits of cellular RANs with sweeping cells with new equivalent channel models that incorporate cell-sweeping.
- Impact Radio Resource Management (RRM) protocols and signalling (initial access, sleep mode procedure, handover, scheduling etc.)
- Comparison with other state of the art coverage enhancement techniques such as mMIMO, COMP, Cell-Free Architecture, and RIS.
- A good degree (preferably Masters) in Electronic Engineering with Communications related subjects
- Programming proficiency in Matlab / C++
- Good mathematical skills in Linear Algebra, Optimization Theory / AI , and Statistical Signal Processing
- Excellent writing skills, prior publications will be advantageous
