Introduction
In July 2018, IEEE WG sent a liaison statement to 3GPP RAN proposing a joint 6 GHz Coexistence Workshop to enable fair and efficient sharing of the unlicensed spectrum between different technologies. 3GPP RAN responded positively to the invitation in September 2018 with a date and location still to be agreed. This presentation provides some thoughts for consideration in preparation of the workshop.

Workshop Preparation
Consider inviting other standard bodies
E.g., WFA
NRU discussions evolving quickly
NR-U SI was scheduled for completion in November 2018
Plan to revise contributions in regard to the latest NR-U SI status.
Conference calls to be provisioned prior to the workshop
IEEE attended 3GPP LAA Workshop in 2015
Lesson learned ?

4. Workshop Agenda Possible topics include:
November 2018
Workshop Agenda
Possible topics include:
6 GHz is a huge opportunity – 1.2 GHz unlicensed spectrum
FCC Notice of Proposed Rulemaking (October 2018) includes GHz, GHz, GHz, GHz
Importance & challenges of fair co-existence in 6 GHz
No or 3GPP incumbents
802.11ax not considered so far by 3GPP (e.g. simulation)
802.11ax not an evolution but a ‘revolution’
802.11ax status / timeline
Specification, certification, deployment
What’s next (EHT, FD)

5. November 2018
Workshop Agenda
Salient ax features (not present in ac) with possible impact on coexistence (e.g., spatial reuse)
Simulation scenarios are based ac & LTE LAA/NR-U
Fairness criterion
Wi-Fi/NR-U in 5 GHz and 6 GHz
Analysis of possible coexistence mechanisms
e.g. technology neutral preamble
LTE LAA/802.11ac field trial results if available
Agree on a fast communication channel between 3GPP RAN and IEEE
