The problem is to obtain the optimal number of base stations (BSs) and their locations on minimized power consumption with requirements of coverage rate and cell load. In this paper, we propose a mathematical model of evaluation index for cell planning and identify the optimization problem. The system model characterizes the total power consumption of planning area, taking into account the radio power,...
A new dedicated resource allocation method for D2D communications in cellular systems employing fractional frequency reuse (FFR) is proposed in this paper. This method consists of three steps. For the first step, the permitted frequency resource set of each D2D link is determined. For the second step, a frequency resource assignment algorithm is proposed which takes both interference and load into...
