Distributed Resource Allocation Schemes for Out-of-Coverage D2D Communications

February 27, 2020
Author(s)
Jian Wang, Richard A. Rouil, Fernando J. Cintron
In many public safety scenarios, Device-to-Device (D2D) communication should be capable of handling out-of-coverage situations, ensuring that D2D devices can communicate directly without the aid of network infrastructure. While a number of resource

Throughput Analysis between Unicast and MBSFN from Link Level to System Level

November 7, 2019
Author(s)
Chunmei Liu, Chen Shen, Jack Chuang, Richard A. Rouil, Hyeong-Ah Choi
Public safety incidents typically involve significant amount of group traffic. This paper initializes our study in exploring the potential spectrum savings and improvement in first responders experience by using Multicast Broadcast Single Frequency Network

System Level Evaluation of UE-to-Network Relays in D2D-enabled LTE Networks

September 13, 2019
Author(s)
Samantha M. Gamboa Quintiliani, Raghav Thanigaivel, Richard A. Rouil
The 3rd Generation Partnership Program (3GPP) introduced UE-to-Network Relays in Long Term Evolution (LTE) Release 13. This technology leverages Proximity Services (ProSe), i.e., the LTE Device-to-device (D2D) communication functionality, to provide user

Guidelines for Generating Public Safety Benchmark Scenario Set

May 1, 2019
Author(s)
Richard A. Rouil, Chunmei Liu, Antonio Izquierdo Manzanares
There is a need to establish well-defined, public safety scenarios for the evaluation of current and future communication technologies for first responders. The scenario descriptions must contain enough details to be considered representative of key public

Access Time Analysis of MCPTT Off-Network Mode over LTE

April 2, 2019
Author(s)
Yishen Sun, Wesley D. Garey, Richard A. Rouil, Priam C. Varin
Public Safety organizations around the world started migrating toward Long Term Evolution (LTE) networks to support the increasing needs for video and data. To address the unique requirements of first responders, the Third 3rd Generation Partnership

Griffith, Fidel Liberal, Robert Escalle, Sonim Technologies, Richard Lau, Vencore Labs, Paul Sutton, Software Radio Systems LTD, Sumit Roy, Sean Sangodoyin, David A. Howe, Fabio C. Da Silva, Alicia Evangelista, Yet2, Brienne Engel, Yet2, John S. Garofolo
This document is a compilation of the slides presented during Day 3 of the 2017 Public Safety Communications Research Program's (PSCR) Annual Stakeholder Conference. Day 3 topics include PSCR research plans and results for Mission Critical Voice, Indoor

Assessing Coverage and Throughput for D2D Communication

July 30, 2018
Author(s)
Jian Wang, Richard A. Rouil
In this paper, we address the issue of assessing the performance of a Device-to-Device (D2D) communication link. Particularly, we design a framework to evaluate performance with respect to the coverage probability and average throughput. Our modeling

Modeling and Simulation Analysis of the Physical Sidelink Shared Channel (PSSCH)

May 24, 2018
Author(s)
David W. Griffith, Fernando J. Cintron, Timothy Hall, Richard A. Rouil
This paper examines the performance of the Long Term Evolution (LTE) Physical Sidelink Shared Channel (PSSCH) in out-of-coverage (OOC) device-to-device (D2D) communication scenarios. We develop a closed form expression for the distribution of the number of

Increasing Public Safety Broadband Network Resiliency Through Traffic Control

February 1, 2018
Author(s)
Richard A. Rouil, Wesley D. Garey, Camillo A. Gentile, Nada T. Golmie
Long Term Evolution (LTE)-based cellular networks are being deployed around the world to provide public safety with enhanced capabilities and access to broadband technology. In the United States, the First Responder Network Authority (FirstNet) is on the

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

Adaptive synchronization reference selection for out-of-coverage Proximity Services (ProSe)

October 8, 2017
Author(s)
Samantha M. Gamboa Quintiliani, Fernando J. Cintron, David W. Griffith, Richard A. Rouil
Proximity services (ProSe) is a Long Term Evolution Advanced (LTE-A) feature that allows User Equipments (UEs) to communicate without the need of routing the data throughout the network. In this paper, we studied the synchronization protocol used by ProSe
