A Millimeter Wave Channel Modeling with Spatial Consistency in 5G Systems

Abstract

The enormous demand of wireless traffic is leading researchers to utilize the huge bandwidth of millimeter wave (mmWave) bands for higher data transmission and larger capacity channel modeling for new wireless standard 5G. However, mmWave channel modeling is still a challenge as it is highly weather sensitive and oppressive for short range line-of-sight (LOS) requirement. In this paper, the characteristics of spatial channel modeling is simulated for 73 GHz mmWave bands using NYUSIM. Spatial consistency channel models for moving users and channel models for static users without spatial consistency consideration have been compared in terms of different channel parameters for both LOS and non-LOS (NLOS) environment. Simulation results indicates that the received power is higher for LOS and NLOS considering spatial consistency channel model compared to the channel models without spatial consistency in urban micro cell scenario. In addition, several power delay profiles and dynamic channel characteristics are presented considering both spatial consistency and without spatial consistency.
