Fluid Antenna Port Prediction based on Large Language Models
Yali Zhang, Haifan Yin, Weidong Li +2
This study seeks to utilize large language models (LLMs) to forecast the moving ports of fluid antenna (FA). By repositioning the antenna to the locations identified by our propose…
Control Signaling for Reconfigurable Intelligent Surfaces: How Many Bits are Needed?
Anders Enqvist, Özlem Tuğfe Demir, Cicek Cavdar +1
Reconfigurable intelligent surfaces (RISs) can greatly improve the signal quality of future communication systems by reflecting transmitted signals toward the receiver. However, ev…
Near-Field SWIPT with gMIMO in the Upper Mid-Band: Opportunities, Challenges, and the Way Forward
Özlem Tugfe Demir, Mustafa Ozger, Ferdi Kara +2
This paper explores the integration of simultaneous wireless information and power transfer (SWIPT) with gigantic multiple-input multiple-output (gMIMO) technology operating in the…
RIS-Assisted Survivable Fronthaul Design in Cell-Free Massive MIMO System
Zhenyu Li, Özlem Tuğfe Demir, Emil Björnson +1
This paper investigates the application of reconfigurable intelligent surfaces (RISs) to improve fronthaul link survivability in cell-free massive MIMO (CF mMIMO) systems. To enhan…
Fair and Energy-Efficient Activation Control Mechanisms for Repeater-Assisted Massive MIMO
Ozan Alp Topal, Özlem Tuğfe Demir, Emil Björnson +1
Massive multiple-input multiple-output (mMIMO) has been the core of 5G due to its ability to improve spectral efficiency and spatial multiplexing significantly; however, cell-edge…
UAV-Based Cell-Free Massive MIMO: Joint Placement and Power Optimization under Fronthaul Capacity Limitations
Neetu R. R, Ozan Alp Topal, Özlem Tuğfe Demir +4
We consider a cell-free massive multiple-input multiple-output (mMIMO) network, where unmanned aerial vehicles (UAVs) equipped with multiple antennas serve as distributed UAV-acces…
