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…
