  1. An Update of IEEE 802.11 TGbd for CITS Bo Sun, ZTE IEEE 802.11 TGbd Chair Date: 2019-10-17 Bo Sun (ZTE)

  2. Background • In the Mar ITU-T CITS conference, IEEE 802.11bd was firstly introduced to the group. • IEEE 802.11-TGbd-Introduction • This document provide the update information of the IEEE 802.11bd progress during the past half year. • All information in this document can be obtained from public sources and the document should be understood with the author’s personal view. Note: “At lectures, symposia, seminars, or educational courses, an individual presenting informationon IEEE standards shall make it clear that his or her views should be considered the personal views ofthat individual rather than the formal position, explanation, or interpretation of the IEEE.”    IEEE-SA Standards Board Operation Manual (subclause 5.9.3) Bo Sun (ZTE)

  3. Re-cap of IEEE 802.11 TGbd • Formed in Dec 2018 • Leadership: • Chair: Bo Sun; • Vice Chair: Hongyuan Zhang; Joseph Levy • Tech Editor: Bahar Sadeghi • Secretary: James Lepp • Target: • Develop IEEE P802.11bd amendment standard • PAR Duration: Dec 2018 ~ Sep 2021 • First meeting: Jan 2019, St. Louis, USA • Latest meeting: Sep 2019, Hanoi, Vietnam • Public website: • http://www.ieee802.org/11/Reports/tgbd_update.htm • Public contributions server: • https://mentor.ieee.org/802.11/documents?is_group=00bd Bo Sun (ZTE)

  4. TGbd Use Cases • Basic safety message (safety, range, backward compatibility, fairness) • Sensor sharing (throughput) • Multi-channel operation (safety channel + other channels) • Infrastructure applications (throughput) • Vehicular positioning & location (LoS and NLoS positioning accuracy • Automated driving assistance (safety, throughput) • Aerial vehicle ITS application (video) • Train to train (high speed) • Vehicle to train (high speed, long range) • V2V see-through (throughput, low latency) Bo Sun (ZTE)

  5. Key Progress • 5 f2f meetings have been held to develop SFD and FRD • Averagely one teleconference between two successive f2f meetings • Over 100 tech submissions presented and discussed • Over 50 tech motions passed in TGbd to develop SFD and FRD • Two adhoc groups formed to accelerate the progress • PHY adhoc, co-chairs: Qinghua Li, Hongyuan Zhang • MAC adhoc, co-chairs: James Lepp, Joseph Levy • Important TG documents • Use Case Document: • https://mentor.ieee.org/802.11/dcn/19/11-19-1342-01-00bd-11bd-use-cases.pptx • SFD: • https://mentor.ieee.org/802.11/dcn/19/11-19-0497-03-00bd-802-11bd-specification-framework-document.docx • FRD: • https://mentor.ieee.org/802.11/dcn/19/11-19-0495-02-00bd-802-11bd-functional-requirements-document.doc • Broad liaisons with lots of V2X-related standard bodies. • Use case liaison with SAE, IEEE 1609, WFA, etc. • Interface-with-upper-layer liaison with IEEE 1609 • Regulatory liaison with IEEE 802.18 Bo Sun (ZTE)

  6. Key Tech Consensus • PHY Layer • Use as much 11ac PHY as possible. • Support backward compatibility with 11p, e.g. keeping 10 MHz L-STF, L-LTF and L-SIG. • Support 10 MHz and 20 MHz bandwidth, e.g. 2x down-clock of IEEE 802.11ac 20 MHz and 40 MHz signal. • LDCP and DCM • Support Midamble • Support MCS up to 256 QAM. • Support Round-Trip-Time Ranging • MAC Layer. • Modification adaptive to new NGV PHY. • Backward compatible and co-exist with 11p • Support 20 MHz channel access • Improve SAP interface with upper layer protocols. • Support of A-MPDU and A-MSDU Bo Sun (ZTE)

  7. IEEE P802.11bd Timeline (updated) • PAR approved Dec 2018 • First TG meeting Jan 2019 • D0.1 Sept 2019  Nov 2019 • D1.0 Letter Ballot Nov 2019  Mar 2020 • D2.0 LB recirculation Mar 2020  Jul 2020 • Form Sponsor Ballot Pool May 2020  Sep 2020 • D3.0 LB recirculation May 2020  Sep 2020 • D3.0 unchanged recirculation July 2020  Nov 2020 • Initial Sponsor Ballot (D4.0) Sept 2020  Jan 2021 • Final 802.11 WG approval July 2021  Nov 2021 • 802 EC approval July 2021  Nov 2021 • RevCom and SASB approval Sept 2021  Dec 2021 Bo Sun (ZTE)
