IEEE 802.11 PDED ad hoc achieved its goals in Vancouver in Mar 2017 IEEE 802.11 PDED achievements in Vancouver in Mar 2017 (agenda, draft/unapproved minutes on Tuesday & Wednesday) Reviewed activities in 3GPP RAN4 related to coexistence testing The testing is going slowly and is at risk Reviewed what has happened so far on the PDED issue Approved a response to 3GPP RAN1 on the PDED issue Heard refined presentation on simulation of LAA/Wi-Fi coexistence Conclusion was changing the ED threshold to -72dBm makes ax WLAN performance worse Reviewed status of EN 301 893 development IEEE 802 will need to make a case to maintain the “802.11 exception” in the next revision of EN 301 893 Discussed future of ad hoc Andrew Myles, Cisco

The SC approved an LS to 3GPP RAN/RAN1/RAN4 Motion The IEEE 802.11 PDED ad hoc recommends to IEEE 802.11 WG and IEEE 802 EC that 11-17-292-03 be approved as a liaison statement from IEEE 802 to 3GPP RAN/RAN1/RAN4 in relation to Issue 3 and Issue 13 in the most recent Liaison Statement from 3GPP RAN1. It is recommended that the IEEE 802.11 WG Chair and IEEE 802 EC Chair be given authority to make any editorial changes they deem necessary. Moved: Seconded: Result: 10/2/2 (Approved) Andrew Myles, Cisco

IEEE 802.11 PDED ad hoc wants to continue its work until at least the Berlin meeting in July 2017 The ad hoc discussed the request of the WG Chair on whether it should Discontinue Continue as an ad hoc Continue as a SC There was consensus that there is more work to be done Discuss the use of PD, ED or other LAA/802.11 coexistence mechanisms with the goal of promoting “fair” use of unlicensed spectrum Probably focusing on work with 3GPP RAN/RAN1 Promote the definition of rules that allows IEEE 802.11ax “fair access” to global unlicensed spectrum Probably focusing on work with ETSI BRAN May also need to consider spatial re-use in addition to coexistence The ad hoc requests it be allowed to continue in current form until July Subsequent discussions with WG Chair indicates he is happy to extend mandate only until May 2017 Andrew Myles, Cisco
