Abstract

The Long Term Evolution (LTE) cellular network is based on Orthogonal Frequency Division Multiple Access (OFDMA) to meet several services and performance requirement. This paper shows the interest of robustness approach due to the uncertainty of traffic distribution while evaluating some antenna parameters. We use a greedy algorithm with different variants to show how a frequency parameter setting can impact the coverage performance indicator based on the SINR metric. The well-known frequency reuse schemes 1x3x3, whereby the entire bandwidth is divided into 3 non-overlapping groups and assigned to 3 co-site sectors within each cell, have been used in our model. Further work must be done on algorithmic approach.
