September 2012 doc. : IEEE 802. 11 -12/1080 r 0 Overview of NDP Probing Procedure [1] • STA transmit NDP Probe Request frame. – NDP Probe Request frame format is defined as follows • SIG field is TBD • AP responses Probe Response/Short Beacon frame after back-off. – Probe Response/Short Beacon frame is broadcasted. • PHY-CCA. indication (busy) primitive has not been detected before the Probe. Timer reaches Min. Channel. Time, then set NAV to 0 and scan the next channel. [IEEE 802. 11 -2012] • After receiving Short Beacon/Probe Response frame, STA may transmit Probe Request frame/Association Request frame or listen to full Beacon frame for obtaining the more information.

September 2012 doc. : IEEE 802. 11 -12/1080 r 0 Proposed SIG Field of NDP Probe Request • SIG Field Information – 1 MHz mode PHY MCS 4 SSID/Interworking Present (when set to 0) 1 SSID/Interworking Present (when set to 1) 1 Access Network Option 8 Compressed SSID 16 Reserved CRC Tail 13 4 6 Reserved CRC Tail 5 4 6 • Compressed SSID is computed as the 32 bit-CRC of SSID. But, 16 LSBs of 32 bit-CRC are included. Submission Slide 5 Yongho Seok, LG Electronics
