Performance Evaluation of 5G Downlink Under Different Beamforming and Scheduling Methods

摘要

The millimeter-wave (mm-wave) technology is considered to be a quantum leap in the wireless communication industry. The 60 GHz band is one of the most attractive fifth generation (5G) bands. That is due to the higher achievable throughput and lower latency when compared to the conventional 4G bands. This paper addresses the 60 GHz system performance evaluation for a cellular downlink transmission in an urban outdoor environment. Taking into consideration the effect of multipath fading, two packet scheduling algorithms are exploited, namely maximum rate (Max C/I) and Round Robin (RR). The performance is evaluated under various phased antenna configurations at both transmitter and receiver sides. From the simulation results, we conclude that scheduling scheme, beamforming and antenna array design play an essential role to offset the effect of fading and interference.
