Source: NTT DoCoMo, RP-160353, 3GPP TSG RAN Meeting #71, Göteborg, Sweden, March 7 - 10, 2016 RAN plenary decided that 5G standardisation will start in the RAN working groups. DoCoMo leads this work and suggested a first time plan for the RAN WGs for Rel.14 and Rel.15.

Next Generation New Radio Access Technology SI
• Objective
– The new RAT will consider all frequency ranges up to 100 GHz
– Target a single technical framework addressing all usage scenarios of TR38.913, including
• Enhanced mobile broadband
• Massive machine-type-communications
• Ultra reliable and low latency communications
– Initial work of SI should allocate high priority on the following areas to enable development of technical
solutions
• Fundamental physical layer signal structure for new RAT
– Waveform based on OFDM, with potential support of non-orthogonal waveform and multiple access
– Basic frame structure(s)
– Channel coding scheme(s)
• Radio interface protocol architecture and procedures
• Radio Access Network architecture, interface protocols and procedures
– Based on the initial study, RAN WG will focus on technical solutions for Phase I at later stage of Rel. 14

The time starting the discussion depends on RAN1
status. RAN4 needs to clarify what kinds of specs need
to clear to start the time and share it with RAN1.
Support R1/2 discussion if any
