Modular Multi-Domain Digital Twin Architecture: Sustainable Intent-Driven 6G Management
Berk Buzcu, Marcin Pakula, Gevher Yesevi Keskin +10
Future 6G networks will operate across distributed and heterogeneous domain infrastructures, making conventional single-domain management insufficient for proactive, trustworthy au…
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…
Energy-Efficient Power Control in Single-User M-MIMO-OFDM System with PA Nonlinearity
Siddarth Marwaha, Pawel Kryszkiewicz, Eduard A. Jorswieck
Although multiple works have proposed energy-efficient resource allocation schemes for Massive Multiple-Input Multiple-Output (M-MIMO) system, most approaches overlook the potentia…
Optimal Distortion-Aware Multi-User Power Allocation for Massive MIMO Networks
Siddarth Marwaha, Pawel Kryszkiewicz, Eduard Jorswieck
Real-world wireless transmitter front-ends exhibit certain nonlinear behavior, e.g., signal clipping by a Power Amplifier (PA). Although many resource allocation solutions do not c…
