Towards Opportunistic Radar Sensing Using Millimeter-wave WiFi

January 1, 2024
Jian Wang, Jack Chuang, Samuel Berweger, Camillo Gentile, Nada T. Golmie
Sensing with communication waveforms has drawn growing interest thanks to the ubiquitous availability of wireless networks. However, the required sensing resources may not always be available in a communication system. In addition, the communication system

Adaptive Channel-State-Information Feedback in Integrated Sensing and Communication Systems

August 28, 2023
Neeraj Varshney, Samuel Berweger, Jack Chuang, Steve Blandino, Jian Wang, Neha Pazare, Camillo Gentile, Nada T. Golmie
Efficient design of integrated sensing and communication systems can minimize signaling overhead by reducing the size and/or rate of feedback in reporting channel state information (CSI). To minimize the signaling overhead when performing sensing

Integrated Sensing and Communication: Enabling Techniques, Applications, Tools and Datasets, Standardization, and Future Directions

December 1, 2022
Jian Wang, Neeraj Varshney, Camillo Gentile, Steve Blandino, Jack Chuang, Nada T. Golmie
The design of integrated sensing and communication (ISAC) systems has drawn recent attention for its capacity to solve a number of challenges. Indeed, ISAC can enable numerous benefits, such as the sharing of spectrum resources, hardware, and software, and

Multi-User MIMO Enabled Virtual Reality in IEEE 802.11ay WLAN

May 16, 2022
Jiayi Zhang, Steve Blandino, Neeraj Varshney, Jian Wang, Camillo Gentile, Nada T. Golmie
Virtual reality (VR) coupled with 360° video has been used in a variety of areas, including gaming, remote learning, and healthcare, among others. The 360° video on which VR applications are based today is mostly low resolution and, in order to improve the

Deep Learning Based Link-Level Abstraction for mmWave Communications

November 18, 2021
Jian Wang, Neeraj Varshney, Jiayi Zhang, David W. Griffith, Nada T. Golmie
Link abstraction is an efficient way for predicting link-level performance (e.g., whether the receiver successfully receives packets through communication links). It can be used to support system-level simulation and facilitate link adaption. Nonetheless

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

May 7, 2021
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

Quasi-Deterministic Channel Propagation Model for an Urban Environment at 28 GHz

April 16, 2021
Neeraj Varshney, Jian Wang, Chiehping Lai, Camillo Gentile
We reduced parameters of the Quasi-Deterministic channel propagation model, recently adopted by the IEEE 802.11ay task group for next-generation Wi-Fi at millimeter-wave, from measurements collected in an urban environment with our 28 GHz directional

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

February 27, 2020
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

An Implementation Proposal for IEEE 802.11ay SU/MU-MIMO Communication in ns-3

June 21, 2019
Hany Assasa, Joerg Widmer, Jian Wang, Tanguy Ropitault, Nada T. Golmie
Wireless communications in the millimeter-wave band bring unprecedented capabilities to achieve wireline performance in wireless networks and alleviate the congestion problem of current wireless technologies. However, efficient wireless networking in this

Methodology for Multipath-Component Tracking in Millimeter-Wave Channel Modeling

March 1, 2019
Chiehping Lai, Roy Sun, Camillo Gentile, Peter B. Papazian, Jian Wang, Jelena Senic
In this paper, we describe an extensive channel-measurement campaign - including 325 unique transmitter-receiver configurations - conducted in a lecture room with our 3D double- directional 60-GHz channel sounder. The receiver was mounted on a mobile robot

Millimeter-Wave Channel Measurement and Modeling: A NIST Perspective

December 7, 2018
Camillo A. Gentile, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley, Peter G. Vouras, Jelena Senic, Jian Wang, Jack Chuang, Ruoyu Sun
The exponential increase in wireless data transmission from smartphones has led to the saturation of the sub-6-GHz bands, forcing cellular providers to migrate to the millimeter-wave (mmWave) regime for 5G. Although available channel bandwidths will grow

Assessing Coverage and Throughput for D2D Communication

July 30, 2018
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
