System-Level Evaluation of 5G NR UE-Based Relays

December 25, 2023
Author(s)
Samantha Gamboa Quintiliani, Aziza Ben Mosbah, Wesley Garey, Chunmei Liu, Richard A. Rouil
The notion of UE-based relays started with the introduction of Proximity Services (ProSe) and Device-to-Device (D2D) communication, and evolved with the adaptation of the Fifth Generation (5G) New Radio (NR) interface. While the main goal of relays is to

Study of 5G New Radio (NR) Support for Direct Mode Communications

May 7, 2021
Author(s)
Fernando Cintron, David W. Griffith, Chunmei Liu, Richard A. Rouil, Yishen Sun, Jian Wang, Peng Liu, Chen Shen, Aziza Ben Mosbah, Samantha Gamboa Quintiliani
In public safety communications, direct mode communication is essential to keep first responders connected, especially when there is no network coverage. Direct mode communication is supported in Third Generation Partnership Project (3GPP) Long Term

Evaluation of Timers Related to ProSe-based UE-to-Network Relays

March 24, 2021
Author(s)
Aziza Ben Mosbah, Samantha Gamboa Quintiliani, Richard A. Rouil
User Equipment (UE)-to-Network Relay functionality was introduced in Release 13 of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) to extend and improve user connectivity using the sidelink (SL) channels. The UE-to-Network Relay

On Upper Bounds for D2D Group Size

February 27, 2020
Author(s)
David W. Griffith, Aziza Ben Mosbah
In this paper, we examine the Physical Sidelink Discovery Channel (PSDCH) for out-of-coverage (OOC) Device-to-Device (D2D) Long Term Evolution (LTE) networks using direct discovery for User Equipments (UEs) that are half-duplex. We derive upper bounds for

Enhanced Transmission Algorithm for Dynamic Device-to-Device Direct Discovery

January 12, 2018
Author(s)
Aziza Ben Mosbah, David W. Griffith, Richard A. Rouil
In order to support the increasing demand for capacity in cellular networks, Long Term Evolution (LTE) introduced Proximity Services (ProSe) enabling Device-to-Device (D2D) communications, defining several services to support such networks. We are

A Novel Adaptive Transmission Algorithm for Device-to-Device Direct Discovery

June 27, 2017
Author(s)
Aziza Ben Mosbah, David W. Griffith, Richard A. Rouil
In this paper we study and improve one service used for Proximity Services and Device-to-Device (D2D) communications: D2D Direct Discovery. As defined in the Third Generation Partnership Project, for both in-coverage and out-of-coverage cases, resource

Group Discovery Time in Device-to-Device (D2D) Proximity Services (ProSe) Networks

May 4, 2017
Author(s)
David W. Griffith, Aziza Ben Mosbah, Richard A. Rouil
Device-to-device (D2D) communications for Long Term Evolution (LTE) networks relies on a discovery process to enable User Equipment (UE) to determine which D2D applications and services are supported by neighboring UEs. This is especially important for

An Long Term Evolution (LTE) Device-to-Device module for ns-3

June 14, 2016
Author(s)
Richard A. Rouil, Fernando Cintron, Aziza Ben Mosbah, Samantha Gamboa Quintiliani
In this paper, we provide an overview of the on-going implementation of a 3rd Generation Partnership Program (3GPP) Proximity Services (ProSe) module in ns-3 to enable the performance evaluation of device-to-device (D2D) discovery and communication in Long
