System Level Performance Evaluation of Location Aware Beamforming in 5G Ultra-Dense Networks

Abstract

Current research is devoted to relation of link and system level parameters for location aware beamforming in fifth generation wireless ultra-dense networks. In spite of majority of works, devoted to this actual topic, there are no estimates for how close to each other we can allow communication for wireless neighbor transceiver devices, utilizing beamforming, when their density grows. As a prerequisite for beamforming on the system level spatial separation is evaluated on the link level. Developed link level model allows to relate antenna array elements number and spatial separation distance at first glance. Implemented system level model relates inter-site distance as a spatial separation with SINR and, thus, prove space-division multiple access capabilities potential in spite of increasing device density. The contribution and scientific novelty of research is an establishment of relation between half-power beam width and spatial separation on the link level, SINR evaluation on the system level and suggestion of an ellipse as a measure of positioning for location aware beamforming.
