A Transport Scheme for Reducing Delays and Jitter in Ethernet-Based 5G Fronthaul Networks

IEEE Access, 2018
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.

Fronthaul-Constrained Cell-Free Massive MIMO With Low Resolution ADCs

IEEE Access, 2020
In cell-free massive MIMO networks, a large number of distributed access points (APs) provide service to a much smaller number of mobile stations (MSs) over the same time/frequency resources.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

UAVs‐Assisted Low‐Bit Quantized CF‐mMIMO Systems With MmWave Communications Under MRC Detection

IET Communications, Volume 19, Issue 1, January/December 2025.
ABSTRACT The cell‐free massive multiple input multiple output (CF‐mMIMO) approach, due to its high coverage and the ability to attenuate the large‐scale fading impacts in wireless communications, has drawn a lot of attention. Additionally, because of their movement ability, low power, and low‐cost employed infrastructures, unmanned aerial vehicles ...

Access Point Selection and Localization for Cluster‐Based Realization of a Device‐to‐Device Cell‐Free 6G Communications Network

IET Communications, Volume 19, Issue 1, January/December 2025.
We introduce a fully distributed framework that leverages belief‐desire‐intention extended (BDIx) agents on user devices to perform dynamic clustering and access‐point selection in a cell‐free 6G network, using both classical and deep‐learning methods for deterministic, scalable AP grouping.

Downlink Power Control for Cell‐Free Massive MIMO System With Radio Stripes

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper investigates downlink power control in cell‐free massive multiple‐input multiple‐output systems utilizing radio stripes, a cost‐effective fronthaul topology. An AP switching technique is proposed to enhance spectral efficiency, followed by the formulation of a weighted sum‐rate maximization problem considering QoS, transmit power, and user ...
