IEEE 802.11 Coexistence SC achieved its goals as an effective discussion forum for coexistence issues IEEE 802.11 Coex SC achievements in Warsaw in May 2018 (agenda) Discussed adaptivity clause in EN 301 893 Agreed (11/0/10) to endorse a submission to ETSI BRAN related to adaptivity Reviewed results of recent 3GPP RAN1 meeting Key message 802.11 stakeholders need to get more involved in NR-U/802.11 coexistence discussion, particularly related to coex simulations Noted 3GPP RAN1 consider 6GHz to be greenfield, and so 802.11 will not have any coexistence benefits based on incumbency; there are proposals that suggest 3GPP believe 802.11 may not have access to some of 6GHz Discussed possibility of better communications with 3GPP; possibly using workshop (in Sept?) Action for Coex SC participants to suggest when, what and how! Did not address a variety of other agenda items Ran out of time! Andrew Myles, Cisco

The SC is proposing a motion to endorse adaptivity refinements to EN 301 893 Motion in SC The IEEE 802.11 Coex SC recommends that the material in 11-18-0708-03 be sent to ETSI BRAN, expressing support for a refinement to the adaptivity clause in EN 301 893 Result: Passed 11/0//10 Proposed motion for WG The IEEE 802.11 WG approves the material in 11-18-0708-04 as a LS to ETSI BRAN that endorses adaptivity refinements in EN 301 893 Moved: Andrew Myles Seconded: Note: the text in 11-18-0708-04 is the same as approved by the SC with a reference added to TR 36.889 as directed by the SC Andrew Myles, Cisco

IEEE 802.11 Coexistence SC will continue its work in San Diego after ETSI BRAN meeting in June 2018 IEEE 802.11 Coexistence SC will meet in San Diego in July 2018 Continue to act as a forum for discussion of coexistence issues between IEEE 802.11 and non-IEEE 802 technologies Review results of ETSI BRAN meeting in June wrt coexistence Review results of most recent 3GPP RAN1 meeting wrt coexistence Consider organising 6GHz Coex Workshop Call to action Coexistence with unlicensed LTE and NR-U is vital for future success of 802.11, in both 5GHz band (where 802.11 is incumbent) & 6GHz band (where the rules might be quite different) If you care then you need to get involved; leaving it to a few individuals or a few companies may lead to an undesirable result!
