Interplay between VAoI, Packet Error Rate, and Delay for Energy-Efficient Remote Monitoring
Yasaman Khorsandmanesh, Zinat Behdad, Emil Bjornson +1
This letter studies energy optimization of short-packet transmission for event-triggered remote monitoring over finite-blocklength wireless links. A wireless sensor node generates…
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…
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…
Fundamentals of Energy-Efficient Wireless Links: Optimal Ratios and Scaling Behaviors
Anders Enqvist, Özlem Tuğfe Demir, Cicek Cavdar +1
In this paper, we examine the energy efficiency (EE) of a base station (BS) with multiple antennas. We use a state-of-the-art power consumption model, taking into account the passi…
Power Allocation for Joint Communication and Sensing in Cell-Free Massive MIMO
Zinat Behdad, Özlem Tuğfe Demir, Ki Won Sung +2
This paper studies a joint communication and sensing (JCAS) system with downlink communication and multi-static sensing for single-target detection in a cloud radio access network…
mmWave Communications for Indoor Dense Spaces: Ray-Tracing Based Channel Characterization and Performance Comparison
Ozan Alp Topal, Mustafa Ozger, Dominic Schupke +2
In this paper, the indoor dense space (IDS) channel at 28 GHz is characterized through extensive Ray-Tracing (RT) simulations. We consider IDS as a specific type of indoor environm…
