Workshop Background and Motivation

Unlicensed spectrum has proven to be a source of very significant socio-economic benefits around the globe, starting in about 1999. The Wi-Fi Alliance recently estimated that the current global economic value of Wi-Fi operating in unlicensed spectrum (2.4GHz and 5GHz) is almost $2 trillion per annum. However, unlicensed spectrum is a resource for sharing by everyone. In the near future, it is hoped that the 6GHz band will be made available globally for unlicensed use. It is vital that all technologies, including IEEE 802.11ax (currently being standardised by the IEEE 802.11 Working Group) and 3GPP NR-U (currently being standardised by 3GPP RAN), share the 6GHz band in a fair and efficient manner.

Workshop Invitation

The IEEE 802.11 Working Group are delighted to invite any interested stakeholders (including technology providers, solution providers, operators and users) to participate in a one day Coexistence Workshop being organized by the IEEE 802.11 Working Group, in collaboration with 3GPP RAN, in Vienna, Austria on 17 July 2019.

The primary objective of the Coexistence Workshop is to discuss issues related to fair and efficient shared operation by IEEE 802.11ax and 3GPP NR-U in the 6Ghz band, including:

       Sharing information on plans for use of future technology standards (particularly IEEE 802.11 and 3GPP NR-U) in the 6 GHz band

       Assessing coexistence issues and topics related to the simultaneous use of IEEE 802.11 and 3GPP NR-U technologies in the 6 GHz band, including coexistence criteria and mechanisms

       Discussing other related coexistence topics of interest, including deployment experience of 3GPP LAA/eLAA coexistence with IEEE 802.11ac in the 5GHz band.

Workshop Agenda

The Coexistence Workshop agenda will include:

              Welcome and Introduction to the Coexistence Workshop

                   Invited standardisation updates

    o   IEEE 802.11ax status

    o   3GPP NR-U status 

    o   IEEE 802.11 EHT plans

                    Invited regulatory update

    o   Brief update on the availability of the 6GHz band for unlicensed use

                Deployment update

    o   Short papers on coexistence experience between 3GPP LAA and IEEE 802.11ac in the 5GHz band

             Coexistence topics

    o   Short papers on any aspect relevant to the Coexistence Workshop’s goals

                Summary of the Coexistence Workshop

    o   Next steps

Call for Papers

IEEE 802 requests that any individual or organisation who wishes to contribute one or more short papers to the Deployment update or Coexistence topics agenda items to submit an outline of the paper, explaining how the paper  will support  the Coexistence Workshop’s goals. Each presentation should focus on a single topic and aim to be about 10 minutes in length. Up to 10 minutes will be scheduled for discussion of each presentation.

The deadline for the submission of outlines is 12 May 2019. Outlines should be sent to the IEEE 802.11 Coexistence SC Chair (Andrew Myles at amyles@cisco.com), copied to the IEEE 802.11 Working Group Chair (Dorothy Stanley  at dstanley@ieee.org). Notifications of accepted outlines will be sent to the authors by 31 May 2019. Authors are required to submit their finalised presentation material by 1 July 2019.

Workshop Logistics

The Coexistence Workshop will be held in Vienna, Austria on Wednesday, 17 July 2019.  There will be a requirement for registration and an associated fee. Further logistical details for the Workshop, including registration links and fees, will be available soon on this page.

          Workshop Duration: 13:00 to 21:00

                 Date: Wednesday, 17 July 2019

                  Location: tbd, Vienna, Austria

IEEE 802 Plenary Meeting

IEEE 802.11 is hosting the Coexistence Workshop during the same week as the IEEE 802 July 2019 Plenary meeting, in adjacent locations. Attendees at the Coexistence Workshop are welcome to  attend the IEEE 802 Plenary meeting, with a separate registration required (see IEEE 802.11 Meeting Schedule for details).
