Carbon-Aware Joint Resource and Energy Scheduling for Cellular Base Stations
Jaebum Park, Yutao Xie, Amitava Ghosh +2
Decarbonizing cellular networks requires coordinating communication-resource and battery operation with time-varying electricity prices and carbon intensity. We jointly optimize ba…
Energy Efficiency Optimization for 5G NR PDSCH: A Cross-Layer Link Abstraction Framework
Jaebum Park, Chan-Byoung Chae, Robert W. Heath
Energy efficiency (EE) optimization for cellular links often assumes Shannon-capacity transmission. The 3GPP New Radio (NR) physical downlink shared channel (PDSCH), however, deliv…
Geometry-Aware DRL for Multi-Subband Scheduling in Satellite-Assisted UAM Networks
Hyung-Joo Moon, Sangha Park, Chan-Byoung Chae +1
In this paper, we investigate downlink scheduling for urban air mobility (UAM) in a cooperative space-air-ground integrated network. Multiple ground stations (GSs) employ narrow th…
Channel2World: A Wireless Foundation Model for RF Environment Representation
Hyung-Joo Moon, Joonkyu Jang, Kwang Soon Kim +3
Wireless channels are commonly treated as link-specific observations, although their multipath structure is governed by the surrounding radio-frequency (RF) environment. In this pa…
Physically Consistent Channel Modeling and Signal Processing for Reconfigurable Wireless Systems
Ahmad Dkhan, Simon Tarboush, Hadi Sarieddeen +3
Reconfigurable antennas are increasingly integrated into multi-antenna communication systems to exploit large apertures while reducing the hardware complexity, energy consumption,…
Energy Efficiency Optimization in Distributed MIMO vRAN via Cross-Layer Link Abstraction
Jaebum Park, Chan-Byoung Chae, Robert W. Heath
Virtualized radio access networks (vRAN) run the compute-intensive multiple-input multiple-output (MIMO) baseband as software on shared servers, which makes energy efficiency (EE)…
Signal Processing Foundations of Reconfigurable Antennas in the Tri-Hybrid MIMO Architecture
Nitish Vikas Deshpande, Joseph Carlson, Siyun Yang +6
To enable larger apertures in multipleinput multipleoutput MIMO systems the trihybrid MIMO architecture offers a promising lowcost and lowpower solution by introducing reconfigurab…
Accelerating vRAN and O-RAN with SIMD: Architectural Perspectives and Performance Evaluation
Jaebum Park, Chan-Byoung Chae, Robert W. Heath
The evolution of radio access networks (RANs) toward virtualization and openness creates new opportunities for flexible, cost-effective, and high-performance deployments. Achieving…
AI-Enhanced Wide-Area Data Imaging via Massive Non-Orthogonal Direct Device-to-HAPS Transmission
Hyung-Joo Moon, Chan-Byoung Chae, Kai-Kit Wong +1
Massive Aerial Processing for X MAP-X is an innovative framework for reconstructing spatially correlated ground data, such as environmental or industrial measurements distributed a…
Beamforming with hybrid reconfigurable parasitic antenna arrays
Nitish Vikas Deshpande, Miguel Rodrigo Castellanos, Saeed R. Khosravirad +3
A parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is ba…
