Qualcomm announce 5G spectrum sharing prototype

Qualcomm has debuted its first 5G New Radio spectrum sharing prototype system and trial platform, built by its subsidiary business Qualcomm Technologies.

The industry is designing 5G NR to get the most out of spectrum available across all spectrum types –licensed, unlicensed and shared spectrum – and across spectrum from lower bands (sub-6 GHz) to high bands in the mmWave range.

Qualcomm Technologies’ prototype system aims to show that 5G spectrum sharing technologies will bring higher levels of mobile broadband performance to shared spectrum to enable fiber-like experiences, as well as extending 5G into new types of deployments, such as dedicated 5G networks for enterprise and industrial IoT.

“Qualcomm Technologies’ new 5G spectrum sharing prototype system adds to our existing 5G NR sub-6 GHz and millimeter wave prototype systems and further demonstrates our commitment to drive and track 3GPP standardization of 5G NR, which is designed with forward compatibility to support new spectrum sharing technologies,” said Matt Grob, executive vice president and CTO at Qualcomm Technologies

“5G NR spectrum sharing innovations enable new spectrum sharing paradigms. This technology will benefit operators with licensed spectrum but also opens the doors to those without licensed spectrum – such as cable operators, enterprise or IoT verticals – to take advantage of the 5G NR family of technologies.”

Spectrum Testbed

This new prototype is based on the Qualcomm Technologies’ sub-6GHz and mmWave 5G NR end-to-end prototypes which includes both base station and user equipment. The Qualcomm Technologies spectrum sharing testbed is expanded to support Listen-Before-Talk technology, wideband waveforms with low latency, and enhancements in the radio and network protocols, on top of which new spectrum sharing technologies are being designed and evaluated.

5G spectrum sharing will expand and enhance the spectrum sharing technologies introduced in LTE, specifically License Assisted Access to aggregate across spectrum types, LTE Wi-Fi Aggregation to aggregate across technologies, CBRS/License Shared Access to share spectrum with incumbents and other deployments, MulteFire to operate stand-alone deployments in unlicensed spectrum, as well as introducing new spectrum sharing paradigms.

Qualcomm Technologies’ new prototype system will be utilized for technology development in 2017 with field trials together with industry leaders to follow.
