Overview of NDP Probing Procedure [1] September 2012 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 ProbeTimer reaches MinChannelTime, 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.

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

Proposed SIG Field of NDP Probe Request September 2012 Proposed SIG Field of NDP Probe Request SIG Field Information 2MHz mode PHY MCS SSID/Interworking Present (when set to 0) Access Network Option Reserved CRC Tail 4 1 8 25 6 MCS SSID/Interworking Present (when set to 1) Compressed SSID Reserved CRC Tail 4 1 32 6 Yongho Seok, LG Electronics

September 2012 Conclusion In this proposal, we suggest SIG Field of NPD Probe Request frame Yongho Seok, LG Electronics
