Input for Coexistence Assurance Document Discussions Oct. 2018 Input for Coexistence Assurance Document Discussions Joerg Robert (FAU Erlangen-Nuernberg) Joerg ROBERT, FAU Erlangen-Nuernberg

Oct. 2018 Motivation The TG4w draft specification has to be accompanied by a coexistence assurance document that show the effect of 4w on existing IEEE standards in the relevant frequency bands This document shall be the basis for the discussion what the coexistence assurance document has to include Joerg ROBERT, FAU Erlangen-Nuernberg

Existing Coexistence Assurance Docs. Oct. 2018 Existing Coexistence Assurance Docs. General guidance is given by 802.19: https://mentor.ieee.org/802.19/dcn/09/19-09-0001-00-0000-writing-a-ca-document.ppt Existing documents 802.15.4g: DCN 15-10/668r5 802.15.4k: DCN 15-12/314r1 802.15.4q: DCN 15-14/709r0 802.15.4u: DCN 15-16/286r0 802.15.4v: DCN 15-16/569r0 Joerg ROBERT, FAU Erlangen-Nuernberg

How to Create the Document ( I / II ) Oct. 2018 How to Create the Document ( I / II ) Proposal: Use the 802.15.4k coexistence document as template as we are defining an amendment to the 802.15.4k FSK PHY Coexistence work with 802.15.4 may be very limited, as all PHYs have already been verified against 4k Only missing system is 4q, but its coexistence document already contains all required information and can be referenced Question: Is this a feasible approach? Joerg ROBERT, FAU Erlangen-Nuernberg

How to Create the Document ( II / II ) Oct. 2018 How to Create the Document ( II / II ) The 802.15.4k does coexistence document does not contain any work wrt. IEEE 802.11ah, which did not exist when 4k was developed New simulation results against 11ah are most likely required Joerg ROBERT, FAU Erlangen-Nuernberg

Simulations Against 802.11ah Oct. 2018 Simulations Against 802.11ah Proposal: Use MCS modes currently under discussion in 802.19 sub-GHz SG Limit parameter sets to worst case scenarios in order to save time Questions: What are worst case parameter sets? What kind of propagation models should we use? What about coding an channel estimation? Who can do the work? Joerg ROBERT, FAU Erlangen-Nuernberg

Oct. 2018 Proposed Next Steps After agreeing on content Joerg will create a skeleton document Using this document the 802.19 will be contacted for guidance In the meantime the required simulation results will be created Joerg ROBERT, FAU Erlangen-Nuernberg
