Dynamic multi-state ultra-wideband mm-wave frequency selection for 5G communication

Abstract

Recent works have brought down the curtain on the best solutions to meet the requirements of the future cellular communication (5G) which so-called Millimeter-wave (mmWave) frequencies that are expected to offer an excellent opportunity to increase data capacity and channel capacity due to the enormous amount of available raw bandwidth. However, the limited coverage range of mm-wave (100m-200m) necessitate the presence of suitable techniques to reduce the outage probability due to propagation impairments. In this paper a dynamic multi state ultra-wideband millimeter wave frequency selection (DMSUWMF-S) is presented based on maximum SINR value at the user equipment (UE's). Two mmWave cellular cell deployment scenarios have been implemented with 2.2km × 2.2km and 3km × 3km based on cell range (150m and 200m) respectively. Three classes of millimeter wave base station according to the three frequencies 73, 38 and 28GHz have been simulated. The UE's have been uniformly generated throughout the simulation area. Based on the evaluation of our proposed scheme, the results have shown an enhancement of overall system performance with an increase in system capacity and reduced outage probability.
