21/12/2021 doc. : IEEE 15 -05 -0547 -01 -004 a Bandplan • The list of criteria for Bandplan Selection has been approved (doc 05/0355 r 03 with 11 criteria ), after discussion and approval of a couple of modifications • The Bandplan approved at Cairn’s has been reconfirmed after voting (selection among a list of proposed bandplans presented in doc 05/0389 r 02, 78 % in favor ). Ref. is doc 05/250/03 • Work on-going now on above-6 -Ghz Bandplan (e. g. 15 -05 -0536 -00 -004 a-above-6 -ghz-frequency-planproposal-tg 4 a. pdf) TG 4 a 3 Philippe Rouzet (STM)

21/12/2021 • doc. : IEEE 15 -05 -0547 -01 -004 a ABOVE 6 GHz Bandplan Status and way forward – Currently no other proposal issued than 15 -05 -0536 by 15. 4 a group (which aligns with Japan and OFCOM tentative masks) – Technical work to start urgently within 15. 4 a group to confirm this is the best achievable solution, in particular to reuse most of the technology intended for below 6 Ghz band (e. g. PRF generation) • Process within TG 4 a – Procedure to incorporate the new part with the existing approved bandplan ? New voting ? – It is assumed that the best achievable bandplan has been agreed upon for below 6 GHz band thus this bandplan should not be modified because of the introduction of the above 6 Ghz one • Positioning within the standard and towards regulation – Either above 6 GHz bandplan is optional, but below 6 GHZ is always mandatory – Or two kinds of devices: the ones that work below 6 GHz and the ones above – Stability of the current OFCOM and Japan spectrum masks?

21/12/2021 doc. : IEEE 15 -05 -0547 -01 -004 a Pulse Modulation • The list of criteria for Modulation has been approved by unanimous consent (doc 05/0424 r 1 ) • New presentations of possible modulations have been shown by their authors: 5/0415 r 1, 5/0231 r 7, 05/0428 r 0 , 05/0429 r 00. 05/0515/01, 5/05/0512 -02 -004 a-common-coherent-noncoherent-modulation • document : [15 -05 -0428 -04 -004 a-modulation-proposal] Source: [Ismail Lakkis] summarizes the IX different modulation options (together with spreading codes) that currently exist TG 4 a 5 Philippe Rouzet (STM)

21/12/2021 doc. : IEEE 15 -05 -0547 -01 -004 a Pulse Modulation • It is desirable to progress in the downselection of the modulation (currently 9 different schemes) • It is desirable to progress in the simulations to finalize the selection of the appropriate modulation. simulation work is ongoing (see next slide). • Note: Progress on simulations has been limited by difficulties in calibrating simulators and selecting a minimum number of cases (CMi, SOP options etc…) • Pulse Modulation activity will be the top priority of Garden Grove UWB PHY meetings TG 4 a 6 Philippe Rouzet (STM)

21/12/2021 doc. : IEEE 15 -05 -0547 -01 -004 a Sub-GHz UWB PHY • A presentation of a possible solution for sub–GHz PHY has been made (doc 5/0390 r 1 ) • A straw poll has indicated that more technical information is desired to approve the current proposed solution or move to a modified or new one • One proposal is to align with the list of criteria for bandplan, modulation and pulse compression as defined for UWB PHY above 3 GHz, with the appropriate modifications. • Sub GHz UWB Phy sub technical Editor agrees and will present a list of criteria together with the corresponding selected parameters of proposition presented in doc 5/0390 r 1 TG 4 a 9 Philippe Rouzet (STM)

21/12/2021 • Misc. doc. : IEEE 15 -05 -0547 -01 -004 a UWB PHY modulation and MAC – Air access scheme to be decided: Collision avoidance or simpler mechanism allowing (statistically rare) collisions – Impact on MAC (primitives, timings) – Interaction with regulation • FCC rulemaking for license exempt wireless com. Networks • Impact on i) traffic and ii) spectrum efficiciency • Interoperability between coherent and non coherent devices to be clarified. Current situation (To Be Checked) is: – All devices must be capable of both PRFs (low and High , see doc 05/0456 r 01) – The mode of operation is decided above the MAC – In a given network (e. g. cell), only one mode exists at a time • Need to discuss on other topics – PHY PPDU Header (options for different modulations, preamble lengths etc), trailer… – Timings (Interframe spacing, turnaround time, …) TG 4 a 10 Philippe Rouzet (STM)
