In actual cellular systems, base station (BS) may not be located in the cell center because of physical restrictions. This paper investigates, assuming such a situation, the effectiveness of BS cooperation (BSC) in MIMO (multiple input multiple output) cellular system under irregular cell geometry. The cell shapes are determined by BS position based on Voronoi diagram, namely, UTs (user terminals)...
This paper considers the problem of base station cooperation (BSC) in the cell edge of multi-cellular system in which, different from conventional works, the BS location is displaced from the hexagonal cell center. The initial cell geometry is nonuniformly determined based on Voronoi diagram, and BS-UT (user terminal) connection is flexibly selected based on channel condition between them. In the...
