SC Operating Rules – Tiger Team • Anybody can vote, present, and make motions • This is a tiger team – it is an ad hoc meeting of the 802.11 Regulatory Standing Committee • Any documents that are generated by this group that are intended for distribution outside of IEEE 802.11 (e.g., 802.18) must be approved with a 75% majority by the larger 802.11 Regulatory SC • Voting on documents must occur at an interim or plenary meeting • Only 802.11 voters may vote on documents to be approved for forwarding to other IEEE 802 working groups • Any submissions to this group must be posted to the IEEE document server (Mentor) • Anyone can view IEEE 802.11 emails and download documents from Mentor: • 802.11 REG SC emails: http://www.ieee802.org/11/email/stds-802-11-reg/ • Mentor documents for download: https://mentor.ieee.org/802.11/documents • Select “REG SC” under groups to view only Regulatory Standing Committee documents Jim Lansford, CSR Technology
Background • FCC allocated 75MHz of spectrum in the 5.9GHz band (5850-5925MHz) for Dedicated Short Range Communications (DSRC) in October 1999 • In FCC NPRM 13-22 (13-49), the FCC requested comments on a potential sharing of the DSRC band, to understand if a feasible sharing solution that protects DSRC users could be developed. • DSRC would remain as a primary user of the band • The new band would be designated U-NII-4 • 802.11ac could be modified to operate in this new UNII-4 band if approved by the FCC • FCC did not specify the framework or etiquette by which band sharing would occur Jim Lansford, CSR Technology
Work to date Objectives of the group Create a document that describes and quantifies possible coexistence mechanisms between DSRC and extensions of the 802.11 base standard in the proposed UNII-4 band, if the FCC allows such band sharing in a future R&O. Possible work items > Review of ITS/DSRC field trials > Review of work to date on coexistence > Presentations on use cases > Presentation of possible coexistence approaches > Modeling/simulation of possible coexistence approaches > Testing, field trials, and presentation of results from proposed prototype approaches Final report > Includes outputs from all work items > One or more “snapshots” (summary of work to date) will be provided to FCC * First snapshot from in mid-January sent to FCC after January 802.11 meeting Jim Lansford, CSR Technology

Remaining agenda items • Future call plans December 26: CANCELLED January 2: CANCELLED January 9: Possible meeting (IEEE meeting is following week) January 16: CANCELLED Other business Adjourn Jim Lansford, CSR Technology
Straw poll question #1 Objective of the Tiger Team: “Create a document that describes and quantifies possible coexistence mechanisms between DSRC and extensions of the 802.11 base standard in the proposed UNII-4 band, if the FCC allows such band sharing in a future R&O.” Do you believe that sharing of the 5.9GHz ITS band should be allowed? • Yes • No • Needs more study • No opinion Jim Lansford, CSR Technology
Straw poll question #2 Regarding the proposal in document 13/994r0 by Peter Ecclesine of Cisco Systems https://mentor.ieee.org/802.11/dcn/13/11-13-0994-00-0reg-proposal-for-u-nii-4-devices.docx {additional links?} Do you believe this proposed band sharing technique has merit and, after developing a more complete definition and field testing, should be considered a basis for a band sharing solution? • Yes • No • Not enough information/needs more study • No opinion Jim Lansford, CSR Technology
Straw poll question #3 Regarding the proposal in document 13/1449r2 by Tevfik Yucek of Qualcomm (and others) https://mentor.ieee.org/802.11/dcn/13/11-13-1449-02-0reg-proposal-for-dsrc-band-coexistence.pptx {additional links?} Do you believe this proposed band sharing technique has merit and, after developing a more complete definition and field testing, should be considered a basis for a band sharing solution? • Yes • No • Not enough information/needs more study • No opinion Jim Lansford, CSR Technology
Straw poll question #4 Which proposal do you support for further specification development and field testing? • The 13/994r0 proposal by Ecclesine [1] • The 13/1449r2 proposal by Yucek [1] • I support a combination of both proposals with additional details added • I believe further study of both proposals independently is needed • Neither – I do not support any band sharing • While I support band sharing, I do not believe either approach can form the basis for an acceptable band sharing solution – we need something different Note 1: Both proposals will need additional development before field testing Jim Lansford, CSR Technology
Straw poll question #5 If it would enhance band sharing, would you support a proposal to move the V2V Safety Channel (currently in Channel 172) to one of the upper channels (180, 182, or 184)? (Note: this could require a rule change) • Yes • No • Not enough information • I don’t support band sharing • No opinion Jim Lansford, CSR Technology
Straw poll question #6 • Would you support a proposal to use one of the upper channels (180/182/184) for BSM traffic instead of Channel 172? (No rule change. Part 95 still applies to Channel 172. Channel 172 would be shared with Part 15 devices) • Yes • No • Not enough information • I don’t support band sharing • No opinion Jim Lansford, CSR Technology
Straw poll question #7 • If band sharing is allowed, would you prefer that the upper edge of the U-NII4 band be at 5.925 GHz (all 75MHz) or 5.895 GHz (only the lower 45MHz)? • Only lower 45MHz • All 75MHz • No opinion • I do not support band sharing All 75MHz Lower 45MHz DSRC Band DSRC Channels 173 177 161 165 169 173 177 80MHz 80MHz Wi-Fi Channels 160MHz Jim Lansford, CSR Technology
Straw poll question #8 • If sharing is only allowed in the lower 45MHz portion of the band (5850-5895MHz), should DSRC only use 20MHz channels in that shared portion of the band? (Note: Channels 172 & 178 in Part 95 are defined as 10MHz in bandwidth, so a rule change may be required) • Yes – only 20MHz DSRC channels in the shared band • No – DSRC should use 10MHz channels • No opinion • I do not support band sharing Jim Lansford, CSR Technology
