Fronthaul for Cloud‐RAN Enabling Network Slicing in 5G Mobile Networks

Wireless Communications and Mobile Computing, 2018
This work considers how network slicing can use the network architecture Cloud‐Radio Access Network (C‐RAN) as an enabler for the required prerequisite network virtualization. Specifically this work looks at a segment of the C‐RAN architecture called the fronthaul network.

Framework for Task Offloading in O‐RAN Architecture for Heterogeneous Computing Applications

Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.
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 ...

Dataplane Measurements On A Fronthaul And Backhaul Integrated Network

, 2017
Future transport networks serving next generation accesses are expected to carry both fronthaul (FH) and backhaul (BH) traffic simultaneously. This new concept of network which integrates the FH and BH traffic over the same transport substrate is called Crosshaul.

An Elastic Optical Network-based Architecture for the 5G Fronthaul

Anais do XXXVI Simpósio Brasileiro de Redes de Computadores e Sistemas Distribuídos (SBRC 2018), 2018
In 5G networks, the traffic demands are expected to increase significantly. To deal with this problem, many research efforts focus on TWDMPON for the fronthaul. However, TWDM-PON suffers from the issue of wasted bandwidth when a demand is smaller than the channel.

Deep Reinforcement Learning‐Based Power Control Optimisation for Maximising Energy Efficiency in mmWave User‐Centric Cell‐Free Massive MIMO

IET Communications, Volume 20, Issue 1, January/December 2026.
The multi‐agent Deep Reinforcement Learning (DRL)‐based uplink power control algorithm significantly improves energy efficiency using multi‐agent Deep Deterministic Twin Policy Gradient (MATD3) with dynamic clustering. The Proposed algorithm outperforms single‐agent DRL and classical methods.

First Real‐Time Softwarization of Complete Coherent DSP Stack with Gardner Timing and Clock Recovery

Electronics Letters, Volume 62, Issue 1, January/December 2026.
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 ...
