Phoenix, AZ, USA, September 19, 2015

A 5G Workshop has been held in Phoenix this week. 550 delegates and over seventy presentations contributed to the discussion, which covered the full range of requirements that will feed TSG RAN work items for the next five years.

In his Workshop Summary (RWS-150073), Dino Flore, RAN Chairman and Workshop Chair, highlighted three high level use cases to be addressed:

• Enhanced Mobile Broadband
• Massive Machine Type Communications
• Ultra-reliable and Low Latency Communications

New radio

There is an emerging consensus that there will be a new, non-backward compatible, radio access technology as part of 5G, supported by the need for LTE-Advanced evolution in parallel. A new Study Item (from RAN#70 in December) will develop scenarios and requirements for the new RAT.

The Workshop Summary stressed the need for “forward compatibility to be a design requirement for the new radio from the get-go” with the Study to “include careful investigation of design options to ensure forward compatibility for all use cases.”

Phasing

There will be two phases for the eventual specification work.

• Phase 1 to be completed by H2 2018 (End of 3GPP Release 15)
• Phase 2 to be completed by Dec 2019 for the IMT 2020 submission and to address all identified use cases & requirements (End of 3GPP Release 16)

Next Steps

• Channel modeling work can start in RAN1 in Q1-16
• RAN to approve a Study Item in December - to develop scenarios and requirements
• RAN to approve the Study Item in March, to allow RAN WGs to evaluate technology solutions for the next generation radio technology
• Companies to look for convergence on the outstanding high level items where there is lack of consensus (See Workshop Summary – Slide 9)
