Joint Beamforming and RIS Deployment Optimization for Outdoor-to-Indoor Coverage at Upper Mid-Band: A Dual-Band Ray-Tracing Study
Mingjun Ying, Guanyue Qian, Xinquan Wang +4
Upper mid-band spectrum is promising for 5G and 6G cellular networks, yet concrete and low-emissivity glass impose over 20 dB of building penetration loss above 2 GHz, degrading ou…
Map-Free Single-Anchor Position Localization Using Multipath Uncertainty at Upper Mid-Band
Xingchen Liu, Mingjun Ying, Xinquan Wang +4
Future 5G-Advanced and 6G systems will exploit directional wideband channels for path-based localization, yet map-free indoor positioning remains challenging because extracted mult…
Omnidirectional UMi Path Loss Models for 3GPP Extension Above 100 GHz Using Extensive Empirical Data Sets from 6.75 to 142 GHz
Xingchen Liu, Homa Nikbakht, Mingjun Ying +5
Extending standardized urban microcell (UMi) path loss (PL) models from the upper mid-band (FR3) to sub-terahertz (sub-THz) frequencies requires measurement-based comparisons spann…
SPARC: Sparse Path-Aware Residual Calibrator for Wireless Ray Tracing at Upper Mid-Band
Mingjun Ying, Guanyue Qian, Xinquan Wang +5
Accurate site-specific ray tracing (RT) is essential for upper mid-band network planning, yet raw RT can produce per-path multipath component (MPC) power errors on the order of 19-…
The Anatomy of RF Chains: Metrics, Measures, and Operating Efficiency
Leonid Belostotski, Arjuna Madanayake, John Nielsen +6
In 1958, Haus and Adler [1] introduced the concept of noise measure. Noise measure is a single quantitative metric that provides a comprehensive basis for comparing devices (indivi…
Optimization of RIS Placement for Satellite-to-Ground Coverage Enhancement
Xingchen Liu, Liuxun Xue, Shu Sun +1
In satellite-to-ground communication, ensuring reliable and efficient connectivity poses significant challenges. The reconfigurable intelligent surface (RIS) offers a promising sol…
How to Differentiate between Near Field and Far Field: Revisiting the Rayleigh Distance
Shu Sun, Renwang Li, Chong Han +3
Future wireless systems are likely to adopt extremely large aperture arrays to achieve higher throughput, wider coverage, and higher spatial resolution. Conventional wireless syste…
