CTTC and InterDigital Expand Joint Research to Tackle 5G/Wi-Fi Spectrum Challenges
February 01 2019 - 4:00AM
The Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) and
InterDigital, Inc. (NASDAQ: IDCC), a mobile technology research and
development company, have expanded their joint research efforts to
advance the next generation of wireless technology. CTTC and
InterDigital are developing solutions for 5G cellular technologies
(including NR, MulteFire) and Wi-Fi/WiGig to cooperate effectively
in millimetre wave unlicensed spectrum (NR-U for mmWave) for
contribution to global standards efforts.
The new research project between CTTC and InterDigital will
focus on NR and NR-U, and coexistence studies with Wi-Fi/WiGig,
including technology development, system proof-of-concepts, and
simulation work, among other areas. An important result of the work
is the design and development of a 3GPP-compliant NR network
simulator, with NR-U capabilities, designed as a pluggable module
to ns-3, the network simulator popular in research and academia.
ns-3 is important given that it offers multi-RAT (Radio Access
Technologies) and multi-band simulation capabilities, including NR,
Wi-Fi/WiGig, LTE (LTE-A, LAA, LTE-U) and other technologies.
“While 5G wireless technology is just beginning to launch in
2019, our work with InterDigital aims to deliver an enhanced mobile
broadband experience that will enable 5G wireless to reach its full
potential upon mass rollout over the next three to five years,"
said Lorenza Giupponi, Senior Researcher and Director of
Institutional Relations, CTTC. “We are working towards making
standalone cellular in unlicensed mmWave a reality, which will pave
the way for new verticals like Industry 4.0, among others.”
In terms of standards contributions, CTTC and InterDigital are
developing Beyond 5G extensions to the 3GPP NR standard that build
on the existing Release 16 3GPP Work Item by extending NR-U to
mmWave unlicensed spectrum (NR-U for mmWave). NR, the global
standard being driven by 3GPP for a new 5G air interface, is a
continuing part of the mobile broadband evolution to deliver on the
requirements of 5G. According to 3GPP’s standardization timeline,
Release 16 will submit an initial full 5G system by early 2020. In
December 2018, 3GPP successfully concluded a Study Item, and has
recently committed to a Work Item on NR-U. Researchers at both CTTC
and InterDigital have evaluated and publicized work that highlights
the performance and capabilities of advancing NR-U into millimetre
wave spectrum.
“This expanded project highlights InterDigital’s role as an
important, trusted research partner, and underscores our specific
focus on testbeds and capabilities that are a fit for academic
research and multi-party consortia,” said Doug Castor, Senior
Director, InterDigital Labs. “The interoperability of various
wireless technologies in unlicensed spectrum is a key area of
research, and one where the combined abilities of CTTC and
InterDigital can make a huge impact.”
The expanded research project builds on an already strong
collaboration. InterDigital and CTTC have been working together on
5G development since 2017, and have an established history and
highly-respected research relationship that stems from consortium
collaborations, such as in European H2020 5G-Public Private
Partnership (PPP) projects.
About CTTC
The CTTC is a non-profit research institution based in
Barcelona, resulting from a public initiative of the Regional
Government of Catalonia. The research group involved in the
collaboration agreement with InterDigital is the Mobile Networks
Department of the Communication Networks Division of CTTC. This
group has a long track record of experience in the area of access
to unlicensed band with LAA (Licenced Assisted Access) and LTE-U,
based on previous collaborations with the Wi-Fi Alliance and
Spidercloud Wireless. For more information on CTTC’s Mobile
