Abstract

The unprecedented growth in cellular traffic forced researchers towards extending the Long Term Evolution (LTE) cellular network to unlicensed bands, which is known as U-LTE. However, this extension is by no means straightforward, because centralized control impeded in traditional LTE BSs challenges the performance and radio resources management of today's cellular networks. To cope with the increasing scarcity of today's cellular architecture and radio resources management, for the first time, we propose Break-Even Point (BEP) as a novel approach for solving the radio resources management problem. In this case, the BEP is modelling where the total remaining throughput of Wi-Fi or Small cell Programmable Base Station (SPBS) equals to the total consuming throughput by Users Equipment (UEs). Therefore, we can identify if Wi-Fi and Femtocell or SPBS are working above or below BEP. By using proposed BEP scheme, we guarantee cellular network utilizations with optimal precision, as well as, performance evaluation indicates that optimal spectrum access and fair distribution by using BEP scheme.
