NR Conformance Testing of Analog Radio-over-LWIR FSO Fronthaul link for 6G Distributed MIMO Networks [PDF]
Optical Fiber Communications Conference and Exhibition, 2023 We experimentally test the compliance with 5G/NR 3GPP technical specifications of an analog radio-over-FSO link at 9 μm. The ACLR and EVM transmitter requirements are fulfilled validating the suitability of LWIR FSO for 6G fronthaul.

Transport Network Design for FrontHaul [PDF]
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017 The evolution of LTE and advent of 5G networks increases further the bandwidth requirements for RAN. In parallel, the deployment of Centralized RAN architecture raises new challenges on the FrontHaul network. The inflexibility of the legacy CPRI is the primary challenge to Virtualized RAN deployments, and there is currently a strong trend towards the ...

Meta-Heuristic Fronthaul Bit Allocation for Cell-Free Massive MIMO Systems [PDF]
IEEE Transactions on Wireless CommunicationsLimited capacity of fronthaul links in a cell-free massive multiple-input multiple-output (MIMO) system can cause quantization errors at a central processing unit (CPU) during data transmission, complicating the centralized rate optimization problem ...

Experimental Validation of Coherent Joint Transmission in a Distributed-MIMO System with Analog Fronthaul for 6G [PDF]
2023 Joint European Conference on Networks and Communications & 6G Summit (EuCNC/6G Summit), 2023 The sixth-generation (6G) mobile networks must increase coverage and improve spectral efficiency, especially for cell-edge users. Distributed multiple-input multiple-output (D-MIMO) networks can fulfill these requirements provided that transmission ...

On the Downlink Capacity of Cell-Free Massive MIMO with Constrained Fronthaul Capacity
Entropy, 2020 We investigate the downlink of a cell-free massive multiple-in multiple-out system in which all access points (APs) are connected in a linear-topolpgy fronthaul with constrained capacity and send a common message to a single receiver.

Performance of Cell-Free Massive MIMO With Joint User Clustering and Access Point Selection
IEEE Access, 2021 We consider an uplink cell-free massive multiple-input multiple-output (MIMO) system, in which the access points are connected to the central processing unit (CPU) through a fronthaul network.
