Strategic Bidding in 6G Spectrum Auctions with Large Language Models
Ismail Lotfi, Ali Ghrayeb
Efficient and fair spectrum allocation is a central challenge in 6G networks, where massive connectivity and heterogeneous services continuously compete for limited radio resources…
A Physics-Aware Framework for Short-Term GPU Power Forecasting of AI Data Centers
Mohammad AlShaikh Saleh, Sanjay Chawla, Sertac Bayhan +2
AI data centers experience rapid fluctuations in power demand due to the heterogeneity of computational tasks that they have to support. For example, the power profile of inference…
Large Language Models as Bidding Agents in Repeated HetNet Auction
Ismail Lotfi, Ali Ghrayeb, Samson Lasaulce +1
This paper investigates the integration of large language models (LLMs) as reasoning agents in repeated spectrum auctions within heterogeneous networks (HetNets). While auction-bas…
On the Resilience of Direction-Shift Keying Against Phase Noise and Short Channel Coherence Time at mmWave Frequencies
Mohaned Chraiti, Ozgur Ercetin, Ali Ghrayeb +1
The rapid variation of the wireless channel (short channel coherence time) and the phase noise are two prominent concerns in Millimeter-wave (mmWave) and sub-Terahertz systems comm…
Secure Pinching Antenna-aided ISAC
Elmehdi Illi, Marwa Qaraqe, Ali Ghrayeb
In this letter, a pinching antenna (PA)-aided scheme for establishing a secure integrated sensing and communication system (ISAC) is investigated. The underlying system comprises a…
Theoretical and Experimental Assessment of Large Beam Codebook at mmWave Devices: How Much is Enough?
Bora Bozkurt, Hasan Atalay Gunel, Mohaned Chraiti +3
Modern millimeter wave (mmWave) transceivers come with a large number of antennas, each of which can support thousands of phase shifter configurations. This capability enables beam…
