CoMP-Assisted NOMA and Cooperative NOMA in Indoor VLC Cellular Systems

no code implementations5 Aug 2021 Mohamed Amine Arfaoui, Ali Ghrayeb, Chadi Assi, Marwa Qaraqe

In this paper, we investigate the dynamic power allocation for a visible light communication (VLC) cellular system consisting of two coordinating attocells, each equipped with one access-point (AP).

Joint Resource Allocation and Phase Shift Optimization for RIS-Aided eMBB/URLLC Traffic Multiplexing

no code implementations5 Aug 2021 Mohammed AL-Mekhlafi, Mohamed Amine Arfaoui, Mohamed Elhattab, Chadi Assi, Ali Ghrayeb

The eMBB allocation problem aims at maximizing the eMBB sum rate by jointly optimizing the power allocation at the BS and the RIS phase-shift matrix while satisfying the eMBB rate constraint.

Deep Learning Based Proactive Optimization for Mobile LiFi Systems with Channel Aging

no code implementations21 Apr 2021 Mohamed Amine Arfaoui, Ali Ghrayeb, Chadi Assi, Marwa Qaraqe

In this paper, a proactive-optimization (PO) approach that can alleviate the LiFi channel aging problem is proposed.

Age of Information Optimization in a RIS-Assisted Wireless Network

no code implementations11 Mar 2021 Ali Muhammad, Mohamed Elhattab, Mohamed Amine Arfaoui, Ahmed Al-Hilo, Chadi Assi

To circumvent the high-coupled optimization variables, and with the aid of bilevel optimization, we decompose the original problem into an outer traffic stream scheduling problem and an inner RIS phase-shift matrix problem.

Integration of IRS in Indoor VLC Systems: Challenges, Potential and Promising Solutions

no code implementations15 Jan 2021 Mohamed Amine Arfaoui, Ali Ghrayeb, Chadi Assi

Visible light communication (VLC) is an optical wireless communication technology that is considered a promising solution for high-speed indoor connectivity.

Reconfigurable Intelligent Surface Enabled Full-Duplex/Half-Duplex Cooperative Non-Orthogonal Multiple Access

no code implementations5 Jan 2021 Mohamed Elhattab, Mohamed Amine Arfaoui, Chadi Assi, Ali Ghrayeb

For the power allocation sub-problem, the optimal closed-form expressions for the power allocation coefficients are derived.

A Downlink Puncturing Scheme for Simultaneous Transmission of URLLC and eMBB Traffic by Exploiting Data Similarity

no code implementations27 Dec 2020 Mohammed AL-Mekhlafi, Mohaned Chraiti, Mohamed Amine Arfaoui, Chadi Assi, Ali Ghrayeb, Amira Alloum

Specifically, coupling URLLC and conventional enhanced Mobile BroadBand (eMBB) through superposition/puncturing naturally arises as a promising option due to the tolerance of the latter in terms of latency and reliability.

Invoking Deep Learning for Joint Estimation of Indoor LiFi User Position and Orientation

no code implementations21 Jul 2020 Mohamed Amine Arfaoui, Mohammad Dehghani Soltani, Iman Tavakkolnia, Ali Ghrayeb, Chadi Assi, Majid Safari, Harald Haas

Light-fidelity (LiFi) is a fully-networked bidirectional optical wireless communication (OWC) that is considered a promising solution for high-speed indoor connectivity.
