Dual Gradient Descent EMF-Aware MU-MIMO Beamforming in RIS-Aided 6G Networks
Yi Yu, Rita Ibrahim, Dinh-Thuy Phan-Huy
Reconfigurable Intelligent Surface (RIS) is one of the key technologies for the upcoming 6th Generation (6G) communications, which can improve the signal strength at the receivers…
EMF-Aware MU-MIMO Beamforming in RIS-Aided Cellular Networks
Yi Yu, Rita Ibrahim, Dinh-Thuy Phan-Huy
Reconfigurable Intelligent Surfaces (RISs) are one of the key emerging 6th Generation (6G) technologies that are expected to improve the link budgets between transmitters and recei…
A Dynamic and Incentive Policy for Selecting D2D Mobile Relays
Rita Ibrahim, Mohamad Assaad, Berna Sayrac
User-to-network relaying enabled via Device-to-Device communications (D2D) is a promising technique for improving the performance of cellular networks. Since in practice relays are…
Distributed vs. Centralized Scheduling in D2D-enabled Cellular Networks
Rita Ibrahim, Mohamad Assaad, Berna Sayrac +1
Employing channel adaptive resource allocation can yield to a large enhancement in almost any performance metric of Device-to-Device (D2D) communications. We observe that D2D users…
Stability Analysis of TDD Networks Revisited: A trade-off between Complexity and Precision
Rita Ibrahim, Mohamad Assaad, Berna Sayrac +1
In this paper, we revisit the stability region of a cellular time division duplex (TDD) network. We characterize the queuing stability region of a network model that consists of tw…
