AT&T and Ericsson World Debut 5G Tech at UT

Millimeter wave is an essential and fundamental component for 5G mobile networks and AT&T’s plans. The 5G demo at TWS showcased the possibility and feasibility of millimeter wave radio access technology for the cellular networks of the future. Developed by Ericsson, the new systems incorporated key 5G technologies, including large system bandwidth, phased arrays with ultra-fast beam steering, feedback-based hybrid precoding, multi-user Multiple Input Multiple Output (MIMO), dynamic beam tracking and beam acquisition.

FCC Announcement Makes New Spectrum Available for Millimeter Wave

The FCC recently announced new spectrum for millimeter wave. The new rules open nearly 11 gigahertz of high-frequency spectrum for mobile and fixed wireless broadband, which include 3.85 GHz of currently licensed spectrum and 7 GHz of unlicensed spectrum. This decision could prove critical for the U.S. to retain its leadership in the field of wireless communications.

WNCG Receives Huawei Award for Best Collaboration

WNCG Profs. Gustavo de Veciana and Jeff Andrews recently received an award for Best Collaboration with the wireless group at Huawei. This international award goes to a funded university collaboration the company deems most impactful from among their offices and partner institutions worldwide.  

“We are very pleased to accept this award,” Prof. de Veciana states. “The experience of working with engineers at Huawei has been very rewarding and fun.”  

Analyzing Uplink Massive MIMO Using Stochastic Geometry

Massive multiple-input multiple-out (MIMO) is a promising technique for 5G cellular networks. Prior work showed that high throughput can be achieved with a large number of base station antennas through simple signal processing in massive MIMO networks. The performance of massive MIMO in a large-scale network with irregular base station locations and random user distributions is not yet fully understood.

Initial Beam Association in Millimeter Wave Cellular Systems: Analysis and Design Insights

Wireless communication via millimeter wave (mmWave) frequencies is a key component of future cellular systems. mmWave deployments will use beamforming with large antenna arrays by both the base stations and mobile stations to ensure sufficient received signal power. Prior work on coverage and rate of mmWave cellular networks focused mainly on the case when base stations and mobile users beamfomring vectors are perfectly designed for maximum beamforming gains.

Waveform Design for Joint Millimeter Wave Communication and Radar

Surface transportation safety can be enhanced by the use of wireless technologies, mainly automotive radar and vehicle-to-vehicle (V2V) communication. Automotive radar provides a high-resolution low-latency approach for a continuous automatic detection and ranging of both communication-enabled and non-communication-enabled transportation users. V2V systems rely on the collaborative communication between vehicles to achieve a real-time cooperative detection and ranging.

Analysis of Interference Cancellation in mmWave Cellular Systems

In this research, WNCG visiting graduate student Amir Jafari, WNCG graduate student Jeonghun Park and WNCG professor Robert Heath address the benefits of interference cancellation in millimeter-wave (mmWave) cellular systems. Considering a multiple antenna communications system with transmitting and receiving antennas, the receiving antennas can either be exploited to decode data streams in order to achieve spatial multiplexing, or alternatively the receiving antennas can be used to cancel the interference.

Prof. Robert Heath Moderates Brooklyn 5G Summit Panel

5G technology will play a major role in the future of automotive systems. Exactly how this technology will be implemented is still up for debate. To discuss current research and possible directions for 5G, industry experts met in New York for the Brooklyn 5G Summit in April 2016.
