Open RAN xApps Design and Evaluation: Lessons Learnt and Identified Challenges
Marcin Hoffmann, Salim Janji, Adam Samorzewski +6
Open Radio Access Networks (RAN) offer diverse economic opportunities. A transition to a flexible, modular approach within the disaggregated RAN framework is crucial, involving car…
Clipping noise cancellation receiver for the downlink of massive MIMO OFDM system
Marcin Wachowiak, Pawel Kryszkiewicz
Massive multiple-input multiple-output (mMIMO) technology is considered a key enabler for the 5G and future wireless networks. In most wireless communication systems, mMIMO is empl…
Why white noise is not enough? On using radio front-end models while designing 6G PHY
Pawel Kryszkiewicz, Pawel Sroka, Marcin Hoffmann +1
From generation to generation there are increasing requirements for wireless standards both in terms of spectral and energy efficiency. While up to now the layered wireless transce…
Green Time-Critical Fog Communication and Computing
Hanna Bogucka, Bartosz Kopras, Filip Idzikowski +2
Fog computing allows computationally-heavy problems with tight time constraints to be solved even if end devices have limited computational resources and latency induced by cloud c…
Beam Management Driven by Radio Environment Maps in O-RAN Architecture
Marcin Hoffmann, Pawel Kryszkiewicz
The Massive Multiple-Input Multiple-Output (M-MIMO) is considered as one of the key technologies in 5G, and future 6G networks. From the perspective of, e.g., channel estimation, e…
Signaling Storm Detection in IIoT Network based on the Open RAN Architecture
Marcin Hoffmann, Pawel Kryszkiewicz
The Industrial Internet of Things devices due to their low cost and complexity are exposed to being hacked and utilized to attack the network infrastructure causing a so-called Sig…
Memory Enabled Bumblebee-based Dynamic Spectrum Access for Platooning Environments
Kuldeep S. Gill, Pawel Kryszkiewicz, Pawel Sroka +2
In this paper, we propose a novel memory-enabled non-uniform sampling-based bumblebee foraging algorithm (MEB) designed for optimal channel selection in a distributed Vehicular Dyn…
