2. doc.: IEEE 802.11-10/1230r0 Submission Introduction The ANA is responsible for administering numbers as described in 11-09/0002r4 (802.11 OM) 11-09/0031r13 is the latest ANA database and indicates that the Type subfield of the MPDU Control Field value 11 is: –Reserved for ANA –frozen for due consideration by WG of an escape mechanism Draft P802.11ad_D1.0 has used one subtype of this value for its own purposes This presentation is intended to stimulate “due consideration” of this use so that the response of the ANA to any request from TGad can be determined November 2010 Adrian Stephens, Intel CorporationSlide 2

3. doc.: IEEE 802.11-10/1230r0 Submission Agenda Describe the TGad usage Pose some likely questions to stimulate debate during this meeting and in the hallways during this session –Straw Polls to test likely responses Try and close out a WG consensus through motion at the closing plenary so that the ANA knows how to respond to any request from TGad November 2010 Adrian Stephens, Intel CorporationSlide 3

4. doc.: IEEE 802.11-10/1230r0 Submission Draft P802.11ad_D1.0 Defines type=11 as extension, and subtype=0000 as mmWaveBeacon Defined in response to.11ad’s need to have a beacon frame with the absolute minimum of overhead –In.11ad, the effective beacon rate for a typical configuration (32 antenna elements) is <1 Mbps; i.e., 3000 times lower than the data rate needed for HDMI (3Gbps) Extension type implicitly inherit rules from 7.1.2 (General frame format) November 2010 Adrian Stephens, Intel CorporationSlide 4

5. doc.: IEEE 802.11-10/1230r0 Submission Discussion Is this an acceptable use for type=11? Do we need any rules for type=11 frames over and above the rules in 7.1.2 (General frame format)? –Are current NAV rules sufficient? (REVmb D4.0) –Presence of additional address fields? –Any rules about size and parsing of payload November 2010 Adrian Stephens, Intel CorporationSlide 5

6. doc.: IEEE 802.11-10/1230r0 Submission Straw Poll Is P802.11ad’s use of type=11, subtype=0000 acceptable to the WG? November 2010 Adrian Stephens, Intel CorporationSlide 6

7. doc.: IEEE 802.11-10/1230r0 Submission Motion (for later) The WG directs assignment of type=11 to “extended” with any additional rules as described in document 11- 10/xxxxrx (to be written based on discussion in WG) The WG directs TGad to generate and include in its draft any additional generic description of “extended” frames consistent with document 11-10/xxxxrx (to be written based on discussion in WG) November 2010 Adrian Stephens, Intel CorporationSlide 7
