Fronthaul cell outage compensation for 5G networks
5G networks are expected to bring the gigabits per second throughput level per user to reality by 2020. This is done using a combination of new and well known technologies such as C-RAN, self-organizing networks, ultra dense networks, massive MIMO, and millimeter waves. In new RAN architectures, C-RAN has been viewed as a promising 5G architecture that

Performance of Cell-Free Massive MIMO With Joint User Clustering and Access Point Selection
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.

ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

Framework for Task Offloading in O‐RAN Architecture for Heterogeneous Computing Applications
This work proposes a task offloading framework in ORAN architecture, optimizing computational assignment across user devices, edge cloud, and regional cloud. By efficiently selecting processing nodes and allocating computational and radio resources, it minimizes delay while accommodating diverse latency requirements for gold, silver, and bronze‐tier ...

Fronthaul Quantization as Artificial Noise for Enhanced Secret Communication in C-RAN
This work considers the downlink of a cloud radio access network (C-RAN), in which a control unit (CU) encodes confidential messages, each of which is intended for a user equipment (UE) and is to be kept secret from all the other UEs.

First Real‐Time Softwarization of Complete Coherent DSP Stack with Gardner Timing and Clock Recovery
ABSTRACT This work demonstrates the first fully softwarized coherent receiver digital signal processing stack implemented on a general‐purpose graphic processing unit (GPU) platform. By introducing a data‐parallel GPU implementation for Gardner‐based timing and clock recovery (TCR), the system achieves complete real‐time receiver operation without ...

A Transport Scheme for Reducing Delays and Jitter in Ethernet-Based 5G Fronthaul Networks
Fronthaul networks are leveraging communication links between the remote radio heads and baseband units in cloud radio access networks, and common public radio interface (CPRI) is an interface to carry time-sensitive traffic over the fronthaul.
