IEEE 802.11 - 3GPP 6 GHz Coexistence Workshop Preparation November 2018 doc.: IEEE 802.11-18/1893r0 November 2018 IEEE 802.11 - 3GPP 6 GHz Coexistence Workshop Preparation Date: 2018-11-08 Authors: Lili Hervieu, CableLabs Lili Hervieu, CableLabs

November 2018 Introduction In July 2018, IEEE 802.11 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. Lili Hervieu, CableLabs

Workshop Preparation Consider inviting other standard bodies E.g., WFA November 2018 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 802.11 contributions in regard to the latest NR-U SI status. Conference calls to be provisioned prior to the workshop IEEE 802.19 attended 3GPP LAA Workshop in 2015 Lesson learned ? Lili Hervieu, CableLabs

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 5.925-6.425 GHz, 6.425-6.525 GHz, 6.525-6.875 GHz, 6.875-7.125 GHz Importance & challenges of fair co-existence in 6 GHz No 802.11 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) Lili Hervieu, CableLabs

November 2018 Workshop Agenda Salient 802.11ax features (not present in 802.11ac) with possible impact on coexistence (e.g., spatial reuse) Simulation scenarios are based 802.11ac & 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 802.11 Lili Hervieu, CableLabs
