Qualcomm Technologies has introduced its first 5G New Radio (NR) spectrum sharing prototype system and trial platform.
The innovation happens at a time when the industry is exploring 5G NR designs to get the best out of 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.
5G NR spectrum sharing innovations enable new spectrum sharing paradigms, according to Qualcomm. This technology will not only 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.
With this innovation, Qualcomm 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 chief technology officer, Qualcomm Technologies.
Further, Qualcomm Technologies spectrum sharing testbed is expanded to support Listen-Before-Talk (LBT) 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 (LAA) to aggregate across spectrum types, LTE Wi-Fi Aggregation (LWA) to aggregate across technologies, CBRS/License Shared Access (LSA) 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, Qualcomm said.
