Vision-Based Reconfigurable Intelligent Surface Beam Tracking for mmWave Communications
Juan Sanchez, Xuesong Cai, Fredrik Tufvesson
Reconfigurable intelligent surfaces have emerged as a technology with the potential to enhance wireless communication performance for 5G and beyond. However, the technology comes w…
RCS-based Quasi-Deterministic Ray Tracing for Statistical Channel Modeling
Javad Ebrahimizadeh, Evgenii Vinogradov, Guy A. E. Vandenbosch
This paper presents a quasi-deterministic ray tracing (QD-RT) method for analyzing the propagation of electromagnetic waves in street canyons. The method uses a statistical bistati…
Enhanced Effective Aperture Distribution Function for Characterizing Large-Scale Antenna Arrays
Xuesong Cai, Meifang Zhu, Aleksei Fedorov +1
Accurate characterization of large-scale antenna arrays is growing in importance and complexity for the fifth-generation (5G) and beyond systems, as they feature more antenna eleme…
Power Allocation for Uplink Communications of Massive Cellular-Connected UAVs
Xuesong Cai, István Z. Kovács, Jeroen Wigard +3
Cellular-connected unmanned aerial vehicle (UAV) has attracted a surge of research interest in both academia and industry. To support aerial user equipment (UEs) in the existing ce…
Empirical Low-Altitude Air-to-Ground Spatial Channel Characterization for Cellular Networks Connectivity
Xuesong Cai, Tomasz Izydorczyk, José Rodríguez-Piñeiro +4
Cellular-connected unmanned aerial vehicles (UAVs) have recently attracted a surge of interest in both academia and industry. Understanding the air-to-ground (A2G) propagation chan…
Dynamic mmWave Channel Emulation in a Cost-Effective MPAC with Dominant-Cluster Concept
Xuesong Cai, Yang Miao, Jinxing Li +3
Millimeter-Wave (mmWave) massive multiple-input multiple-output (MIMO) has been considered as a key enabler for the fifth-generation (5G) communications. It is essential to design…
A Centralized and Scalable Uplink Power Control Algorithm in Low SINR Scenarios
Xuesong Cai, István Kovács, Jeroen Wigard +1
Power control is becoming increasingly essential for the fifth-generation (5G) and beyond systems. An example use-case, among others, is the unmanned-aerial-vehicle (UAV) communica…
Air-to-Ground Channel Characterization for Low-Height UAVs in Realistic Network Deployments
José Rodríguez-Piñeiro, Tomás Domínguez-Bolaño, Xuesong Cai +2
Due to the decrease in cost, size and weight, \acp{UAV} are becoming more and more popular for general-purpose civil and commercial applications. Provision of communication service…
Joint Modeling of Received Power, Mean Delay, and Delay Spread for Wideband Radio Channels
Ayush Bharti, Ramoni Adeogun, Xuesong Cai +4
We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as th…
An Empirical Air-to-Ground Channel Model Based on Passive Measurements in LTE
Xuesong Cai, José Rodríguez-Piñeiro, Xuefeng Yin +3
In this paper, a recently conducted measurement campaign for unmanned-aerial-vehicle (UAV) channels is introduced. The downlink signals of an in-service long-time-evolution (LTE) n…
