PIMRC’14 Covered Critical 5G Topics – and We Were a Part of It

September 17, 2014 / 5G, LTE, WiFi, 3GPP / Posted By: Stephanie Stocker

PIMRC‘14 (IEEE 25th Annual International Symposium on Personal, Indoor and Mobile Radio Communications), which ran from September 2-5 in Washington, DC, was a huge success, and InterDigital is proud to have been a significant contributor. The conference was focused on 5G technologies, aligning closely with our own focus.

Conference topics ranged from innovative enhancements to network architectures to groundbreaking and potentially controversial new concepts. As the place where all sides of the industry come together to discuss ideas, PIMRC was the perfect venue for these conversations.

One panel, “Opportunities and Challenges for LTE (-U) and WiFi Coexistence in Unlicensed and Shared Spectrum,” included InterDigital’s Mihaela Beluri, and addressed the hot-button issue of LTE using unlicensed spectrum. Mihaela discussed possible solutions to what seems to be a controversial topic. Doug Castor, also one of our engineers, spoke on a panel entitled “mm-Waves Technology as an Essential Element for Next Generation Mobile Cellular Systems,” which discussed the emerging evidence showing mm-Wave as a viable solution for network capacity growth.

In addition to the panels, two sessions were chaired by InterDigital employees, with Meilong Jiang chairing “Limited/Implicit Feedback” and Ahmed S. Ibrahim chairing “Physical Layer Network Coding.” Our engineers also contributed three papers to the technical program: “Reliable RF Beamforming for Millimeter Wave MIMO-OFDM Systems” (Ahmed S. Ibrahim), “Efficient Adaptive Vertical Downtilt Schemes in LTE-Advanced Networks” (Meilong Jiang, Mohsen Hosseinian, Moon-il Lee, Janet Stern-Berkowitz), and “Sub-Channel Selection for Multi-User Channel Access in Next Generation WiFi” (Hanqing Lou, Juan Fang, Oghenekome (Kome) Oteri, Monisha Ghosh, Pengfei Xia, Robert L. Olesen).

The timing of these discussions at PIMRC is critical – not only is 3GPP discussing LTE-U for a decision expected to be released this month, but the industry is gearing up for the 2015 WRC (World Radio Conference), held every few years as a global gathering of regulatory bodies and standards groups. During that conference,  important decisions about the global use of radio spectrum and how to seamlessly deploy technologies worldwide will be discussed.
