Abstract
The diffusion and demand of mobile communication services are still growing rapidly nowadays. Users are no longer satisfied with merely speeches but eager to communicate with each other by multimedia services. That’s the reason why the approach to the base station deployment optimization problem is so urgent and important.
Many researches have been pronounced to solve the deployment problem. We combined the most important issues, such as downlink SIR constraint, uplink SIR constraint, soft handover, sectorization, and power control, frequency assignment into consideration.
We developed a mathematical programming model to describe this joint design problem. It turns out to be a non-linear non-convex mixed integer programming problem. A set of heuristic solution procedures based on Lagrangian relaxation methods is proposed to solve the complicated problem.
