4 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 ] 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. Yongho Seok, LG Electronics

5 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

6 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

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