This work introduces a modular power model that captures the interplay between radios, fronthaul, and cloud processing and highlights how design choices, such as functional splits and precoding strategies, shape both fronthaul data load and total power consumption.
A network energy-efficiency (EE) maximization framework for the uplink of acell-free massive MIMO with wireless fronthaul, jointly optimizing the integrated access and fronthaul (IAF) resource split, the adaptive per-AP quantization resolution, and the fronthaul powers, and treating the time-division and frequency-divi...
The wireless physical (PHY) layer has enabled successive generations of cellular systems through advances in modulation, coding, waveforms, and multiple-input multiple-output (MIMO) transmission. This article assesses whether these techniques are now approaching maturity and where substantial further gains remain possi...
Cell-free massive multiple-input multiple-output (CF-mMIMO) is a promising architecture for future sixth-generation (6G) wireless networks because cooperation among geographically distributed access points enables seamless connectivity, more uniform quality of service, and improved spectral and energy efficiency. Howev...
This letter investigates a multi-cell reconfigurable intelligent surface (RIS)-assisted cloud radio access network (Cloud-RAN), where multiple remote radio heads (RRHs) are connected to a central unit (CU) via limited-capacity fronthaul links, and multiple user equipments (UEs) in each cell are supported by dedicated R...
In this work, we investigate an energy-efficient design in Cloud Radio Access Network (C-RAN) system with integrated sensing and communication (ISAC), where geographically distributed remote radio heads (RRHs) are coordinated by a central controller to simultaneously support communication users and sensing targets. Alt...
This paper studies the uplink performance of OFDM-based cell-free massive MIMO systems in the presence of hardware impairments affecting both low-cost access points and wireless fronthaul transceivers. We consider a centralized architecture with functional split option~8, where the sampled baseband signals are forwarde...
