  1. Clarification of the STA’s listening duration for Probe Response monitoring • Date: 2012-05-16 Authors: Giwon Park, LG Electronics Inc.

  2. Abstract • This contribution clarifies the Probe Response omission and Probe Response broadcasting procedure. Giwon Park, LG Electronics Inc.

  4. Probe Response Omission and Probe Response broadcasting • IEEE802.11-12/0151r7 describes “An FILS (Fast Initial Link Setup) Capable AP may omit transmission of Probe Response frame to FILS capable STA(Station)s if the TBTT occurs within a predefined time interval.” • IEEE802.11-12/0151r7 describes “ An AP may respond to multiple Probe Requests from one or more FILS capable STAs with a single broadcast addressed response frame.” • AP shall know the STA’s Probe Timer (i.e., Min listening duration, max listening duration) for Probe Response omission and Probe Response broadcasting. • Current SFD only described max listening duration for which the STA indicates it will wait for Probe Response transmission. • STA may include a wait-time-for-Probe-Response element to Probe Request. • AP shall know STA’s min listening duration as well as max listening duration. Background Giwon Park, LG Electronics Inc.

  5. STA may include a wait-time-for-Probe-Response element to Probe Request to provide a min listening duration for which the STA indicates it will wait for Probe Response transmission. Proposal Giwon Park, LG Electronics Inc.

  6. Example of Probe Response Omission Example Figure1 . Omission of the Probe Response Giwon Park, LG Electronics Inc.

  7. Knowing the STA dependent time window (i.e., min listening duration, max listening duration) allows AP to omit or broadcast the Probe Response. Conclusion Giwon Park, LG Electronics Inc.

  8. Modify the text of SFD 6.1.7 as following: “STA may include a wait-time-for-Probe-Response element to Probe Request to provide a min and max listening duration for which the STA indicates it will wait for Probe Response transmission.” Straw poll Giwon Park, LG Electronics Inc.

  9. Modify the text of SFD 6.1.7 as following: “STA may include a wait-time-for-Probe-Response element to Probe Request to provide a min and max listening duration for which the STA indicates it will wait for Probe Response transmission.” Moved : Seconded: Yes: No: Abstain: Motion 1 Giwon Park, LG Electronics Inc.
