Cell Planning Schemes Considering Mass Mobility for Railway Tracks

Abstract (in Japanese) (See Japanese page) 
(in English) The traffic growth for mobile communications even in trains is expected because cost conscious users fade due to flat rate pricing. Since CDMA systems are characterized as interference-limited systems, an effective cell planning is required, considering the mass mobility in trains, when the traffic in trains increases. We have proposed a fundamental cell planning scheme for a mass of accessing users along railway tracks for only a single time period in CDMA systems. In this paper, we propose more practical cell planning schemes considering the different numbers of accessing users through multiple time periods. Moreover, a sequential scheme is also proposed for a large number of time periods.
