Performance Evaluation of 6-Sector-Site Deployment for Downlink UTRAN Long Term Evolution

In this paper, the authors present the results on performance evaluation of 6-sector-site deployment and compare against 3-sector-site deployment in the downlink UTRAN LTE systems. To facilitate the performance evaluation a quasi-dynamic multicell system level simulator that follows the 3GPP UTRAN LTE specifications has been used. A significant gain in the order of 88% in site capacity is achieved by changing the 3-sectorsite deployment by 6-sector-site deployment. A mixed network topology with a combination of 3 and 6-sector-site deployment has been also considered and its potential benefits investigated.
