2 doc.: IEEE /0675r0 SubmissionJim Lansford, CSR Technology Abstract Summary of activities in the IEEE (Regulatory Standing Committee) DSRC Coexistence Tiger Team since the March F2F in Beijing. May 2014 Slide 2

3 doc.: IEEE /0675r0 Submission Background FCC allocated 75MHz of spectrum in the 5.9GHz band ( MHz) for Dedicated Short Range Communications (DSRC) in October 1999  In FCC NPRM (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 ac 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 May 2014 Jim Lansford, CSR TechnologySlide 3

4 doc.: IEEE /0675r0 Submission Work to date Objectives of the group Create a document that describes and quantifies possible coexistence mechanisms between DSRC and extensions of the 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 in mid-January May 2014 Jim Lansford, CSR TechnologySlide 4

6 doc.: IEEE /0675r0 Submission Highlights from CCA discussion Add new 10MHz CCA to ac –Use Carrier Sense of p preamble, NOT energy detect No Changes to DSRC –Similar to a protection, but 10MHz CCA Some changes to ac –New CCA for 10MHz BW – not in existing spec –DSRC Channels 172 and 178 sensed with CCA – other channels TBD –CCA for 10MHz BW exactly the same as a detection at ½ clock rate –13/994r0 suggests a “NAV” during and for 10 seconds after the last PHY-CCA.indication(BUSY,(DSRC10_CCA)) –Other details: CCA level, SIFS, slot times, etc. need to be worked out May 2014 Jim Lansford, CSR TechnologySlide p PPDU

7 doc.: IEEE /0675r0 Submission Future Work Anticipated presentations between now and San Diego Additional presentations on existing proposal(s) Channel models Additional coexistence proposals Some initial simulation results expected in the summer Invitation for future presentations: –How CCA works –DSRC field trials –Use cases –Proximity of public access points to heavily traveled highways May 2014 Jim Lansford, CSR TechnologySlide 7
