  1. doc.: IEEE 802.11-24/0717r0 May 2024 Bluetooth SIG May 2024 Update Date: 2024-03-13 Authors: Name Company Address Phone email Rich Kennedy Bluetooth SIG Kirkland, WA +1-737-202-7014 rkennedy@bluetooth.com Submission Slide 1 Rich Kennedy (Bluetooth SIG)

  2. doc.: IEEE 802.11-24/0717r0 May 2024 Abstract This is an update on Bluetooth SIG actions and plans for sharing the 5 and 6 GHz bands with incumbents and unlicensed/license- exempt devices. Submission Slide 2 Rich Kennedy (Bluetooth SIG)

  3. doc.: IEEE 802.11-24/0717r0 May 2024 Agenda • Bluetooth Sharing Goals • The Overall Bluetooth SIG Plan • Recent Actions • ETSI BRAN #124 (June) planning • Recent actions • Bluetooth Next Steps Submission Slide 3 Rich Kennedy (Bluetooth SIG)

  4. doc.: IEEE 802.11-24/0717r0 May 2024 Bluetooth Sharing Goals The Bluetooth SIG recognizes the contribution the Wi-Fi industry has made in opening the 6 GHz band for unlicensed/license-exempt sharing to grow the technology Today, Bluetooth technology needs to secure its future growth – The 83.5 MHz of the 2.4 GHz band is not a sufficient hedge against congestion or sufficient to support innovation Bluetooth and Wi-Fi successfully shared the 2.4 GHz band for many years – Unfortunately, most of 5 GHz is not viable for Bluetooth, i.e., indoor restrictions and DFS – 5.8 GHz band available in many regulatory domains – Narrowband technology already deployed in U-NII-3 The 6 GHz band has room for Bluetooth and Wi-Fi, and there is time to develop optimal sharing mechanisms We will work closely with the Wi-Fi industry in IEEE 802 and Wi-Fi Alliance to enable Bluetooth sharing these band equitably • • • • • Submission Slide 4 Rich Kennedy (Bluetooth SIG)

  5. doc.: IEEE 802.11-24/0717r0 May 2024 The Overall Bluetooth SIG Plan • Create an industry coalition of Bluetooth companies to drive regulatory and standards changes just as Wi-Fi did – Including companies with both Wi-Fi and Bluetooth businesses – Collaborate with Wi-Fi industry to drive needed changes • Work with SDOs to develop optimum spectrum sharing methods and advance regulatory/standards to codify them as required – ETSI BRAN New Work Item adopted in September 2023 (BRAN #120) • The detailed plan can best be developed working together • Now that the FCC has completed the first round of VLP decisions, we are requesting another for narrowband sharing (without geofencing) – Chairwoman Rosenworcel said there will be a number of additional NPRMs Submission Slide 5 Rich Kennedy (Bluetooth SIG)

  6. doc.: IEEE 802.11-24/0717r0 May 2024 ETSI BRAN #124 Planning • Six Rapporteur’s and one Ad Hoc meetings are scheduled before BRAN #124 – April 22, 23, 24*, 25*, May 21 and 24 Rapporteur’s Meetings – May 23 Ad Hoc Meeting A group of companies including Bluetooth SIG will make proposals for LBT channel access mechanism(s) for consideration The plan is to have draft text ready for the June BRAN meeting for channel access provisions – No square brackets! Additional work needs to be done before it is ready to begin the formal approval process – EDT levels, LBT exceptions for low duty cycle operation, Occupied Bandwidth, In-band emissions, Out-of-band emissions, and Short Control Signaling • • • *Cancelled – no discussion topics Submission Slide 6 Rich Kennedy (Bluetooth SIG)

  7. doc.: IEEE 802.11-24/0717r0 May 2024 ETSI BRAN New Work Item Provisions • (1) To develop a channel access mechanism for Narrowband Frequency Hopping equipment operation • (2) To develop mechanisms enabling LPI client-to-client operations in accordance with ECC/DEC/(20)01 and EC Decision 2021/1067 on 6 GHz WAS/RLANs • (3) To consider further development of FBE and LBE parameters for channel access mechanism • (4) To consider inclusion of new channelization to support next generation technologies (bandwidths exceeding 160 MHz, e. g. 320 MHz) Submission Slide 7 Rich Kennedy (Bluetooth SIG)

  8. doc.: IEEE 802.11-24/0717r0 May 2024 Recent Actions • Bluetooth SIG meeting April 2024 meeting with the FCC – OET Chief suggested we file a Petition for Rulemaking in June – Commissioners very supportive of Bluetooth in 6 GHz • Draft text for EN 303 687 in final review – Timing parameters must be approved by the group prior to ETSI BRAN adoption – Anticipate it will be added to the draft in June, approved in September • Industry coalition (6NB) being formed to drive regulatory acceptance – Similar to the Wi-Fi industry 6USC – Expenses not anticipated Submission Slide 8 Rich Kennedy (Bluetooth SIG)

  9. doc.: IEEE 802.11-24/0717r0 May 2024 Bluetooth Next Steps • Submitting a Petition for Rulemaking to the FCC for narrowband operation inclusion in the 6 GHz rules in June • Participating in and contributing to the ETSI BRAN development of narrowband rules in 6 GHz (EN 303 687) – Four online Rapporteur’s meetings and one ad hoc meeting* prior to BRAN #124 – ETSI BRAN #124 June 2024, #125 in September, #126 in October, #127 in December • Exploring enhanced sharing mechanisms for the 5725 – 5850 MHz band • Further regulatory action needed on the 5.8 GHz band globally – EU: EN 300 440-1 (non-specific SRD for radio communication) must be updated due to lack of recent traction on WI created Jan-2019, otherwise may be heading towards deprecation – China: Bluetooth type-approval requirements discussion with MIIT *Rapporteur’s meetings are working sessions; decisions can be taken at ad hoc meetings.
