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…
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)…
Switch-DFT: Adaptive Waveform and MIMO Switching for Energy-Efficient Base Stations
Jaebum Park, Chan-Byoung Chae, Robert W. Heath
Energy efficiency has emerged as a critical challenge in modern base stations (BSs), as the power amplifier (PA) consumes a substantial portion of the total power due to its limite…
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…
