Towards Standardizing OTFS: A Candidate Waveform for Next-Generation Wireless Networks
Mingcheng Nie, Ruoxi Chong, Shuangyang Li +5
The standardization of the sixth-generation (6G) has recently commenced to address the rapidly growing demands for enhanced wireless network services. Nevertheless, existing wirele…
Optimizing Fronthaul Quantization for Flexible User Load in Cell-Free Massive MIMO
Fabian Göttsch, Max Franke, Arash Pourdamghani +2
We investigate the physical layer (PHY) spectral efficiency and fronthaul network load of a scalable user-centric cell-free massive MIMO system. Each user-centric cluster processor…
User-Centric Cell-Free Wireless Networks for 6G: Communication Theoretic Models and Research Challenges
Fabian Göttsch, Giuseppe Caire, Wen Xu +1
This paper presents a comprehensive communication theoretic model for the physical layer of a cell-free user-centric network, formed by user equipments (UEs), radio units (RUs), an…
Joint Fronthaul Load Balancing and Computation Resource Allocation in Cell-Free User-Centric Massive MIMO Networks
Zhiyang Li, Fabian Göttsch, Siyao Li +2
We consider scalable cell-free massive multiple-input multiple-output networks under an open radio access network paradigm comprising user equipments (UEs), radio units (RUs), and…
