Massive MIMO Beam Management in Sub-6 GHz 5G NR
Ryan M. Dreifuerst, Robert W. Heath, Ali Yazdan
Beam codebooks are a new feature of massive multiple-input multiple-output (M-MIMO) in 5G new radio (NR). Codebooks comprised of beamforming vectors are used to transmit reference…
SuperCell: A Wide-Area Coverage Solution Using High-Gain, High-Order Sectorized Antennas on Tall Towers
Pratheep Bondalapati, Abhishek Tiwari, Mustafa Emin Sahin +6
In this article we introduce a novel solution called SuperCell, which can improve the return on investment (ROI) for rural area network coverage. SuperCell offers two key technical…
Optimizing Coverage and Capacity in Cellular Networks using Machine Learning
Ryan M. Dreifuerst, Samuel Daulton, Yuchen Qian +7
Wireless cellular networks have many parameters that are normally tuned upon deployment and re-tuned as the network changes. Many operational parameters affect reference signal rec…
Optimization of Power Transfer Efficiency and Energy Efficiency for Wireless-Powered Systems with Massive MIMO
Talha Ahmed Khan, Ali Yazdan, Robert W. Heath
Massive MIMO is attractive for wireless information and energy transfer due to its ability to focus energy towards desired spatial locations. In this paper, the overall power trans…
Optimal User Loading in Massive MIMO Systems with Regularized Zero Forcing Precoding
Sungwoo Park, Jeonghun Park, Ali Yazdan Panah +1
We consider a downlink multiuser multiple-input multiple output (MIMO) system employing regularized zero-forcing (RZF) precoding. We derive the asymptotic signal-to-leakage-plus-no…
