Analysis of Bandwidth Requirement of Users in Flexible Reuse Cellular Networks

摘要

In flexible frequency reuse scheme namely fractional frequency reuse (FFR), the total frequency resource is divided logically into cell center and cell edge user bands. However, while frequency resource is partitioned into two segments, the amount of average bandwidth required by cell center and cell edge users is quite different and influences the system performance and design. We developed the analytical approach to evaluate the average bandwidth required by cell center and cell edge users for real time (RT) traffic. It is seen that the analytical results are closely matched with the simulations and indicate that the model is a good approximation for bandwidth requirement of users in a cellular environment.
