A Unified E2E Energy Efficiency Testing Framework for Open RAN
Marcin Hoffmann, Marcin DryjaÅski, Adrian Kliks +4
Energy efficiency (EE) is one of the key challenges for contemporary and future mobile networks, including within the Open Radio Access Network (O-RAN) architecture. However, there…
Large-scale wireless network management via Open-RAN Tandem Apps: Cell on/off switching use case
PaweÅ Kryszkiewicz, Åukasz KuÅacz, Marcin PakuÅa +5
With growing mobile-network complexity, management and optimization have become increasingly difficult. Centralized algorithms face high control-data overhead and computational loa…
Radio Environment Map for Energy-Efficient User-Centric Cell-Free M-MIMO Network
Marcin Hoffmann, PaweÅ Kryszkiewicz
This paper proposes a Radio Environment Map (REM) for energy-efficient (EE) serving cluster formulation in a user-centric cell-free network. By incorporating the location of the us…
Impact of Nonlinear Power Amplifier on Massive MIMO: Machine Learning Prediction Under Realistic Radio Channel
Marcin Hoffmann, PaweÅ Kryszkiewicz
M-MIMO is one of the crucial technologies for increasing spectral and energy efficiency of wireless networks. Most of the current works assume that M-MIMO arrays are equipped with…
An Open-RAN Testbed for Detecting and Mitigating Radio-Access Anomalies
Hanna Bogucka, Marcin Hoffmann, PaweÅ Kryszkiewicz +1
This paper presents the Open Radio Access Net-work (O-RAN) testbed for secure radio access. We discuss radio-originating attack detection and mitigation methods based on anomaly de…
O-RAN for Energy-Efficient Serving Cluster Formulation in User-Centric Cell-Free MMIMO
Marcin Hoffmann, PaweÅ Kryszkiewicz
The 6G Massive Multiple-Input Multiple-Output (MMIMO) networks can follow the so-called User-Centric Cell-Free (UCCF) architecture, where a single user is served by multiple Access…
