doc.: IEEE /1177 Submission September 2013 Giwon Park, LG ElectronicsSlide 1 Clarification of the Link Setup Bursty parameter (CID 2547, 3214) Date: Authors: NameAffiliationsAddressPhone Giwon ParkLG

doc.: IEEE /1177 SubmissionSlide 2 Abstract This presentation introduces a part which needs clarification of Differentiated Initial Link Setup (DILS) procedure and clarifies incomplete procedure. Slide 2 September 2013 Giwon Park, LG Electronics

doc.: IEEE /1177 SubmissionSlide 3 Background Link Setup Bursty – D1.0 specified the Link Setup Bursty parameter in the ILSC information field. –But, there is no STA behaviour on this parameter. –STAs behaviour needs to be defined. Slide 3 September 2013 Giwon Park, LG Electronics

doc.: IEEE /1177 SubmissionSlide 4 Previous meetings resolution on this Regarding the Link Setup Bursty parameter, STAs procedure was deleted in Geneva meeting. –Reference ai-some-cids-resolutions –D1.0 just specified AP procedure. Slide 4 September 2013 Giwon Park, LG Electronics

doc.: IEEE /1177 SubmissionSlide 5 Previous meetings resolution on this (Contd) Santosh introduced KDDI( ai- frequency-of-association-request-in-kddi-data)s material in the Geneva meeting for resolutions of the CIDs 1142, 1220, 1446 and –I think that this KDDIs material is not suitable for this resolution. STA sends the Authentication Request frame after receiving the Beacon frame. But this material is introducing the Association Request frame. STA already may be distributed via Authentication Request frame. Slide 5 September 2013 Giwon Park, LG Electronics

doc.: IEEE /1177 SubmissionSlide 6 Proposal I proposed a uniform distribution method to distribute STA's initial access load in r0. Motivation of the proposal –Differentiated Initial Link Setup procedure is based on the ILS User Priority. In the case that AP doesnt know the ILS User priority of the STAs, the AP should distributes the STAs. –MAC filtering method doesnt fully distribute the STAs which received the Beacon frame. Maximum 50% distribution is just possible. For example, if the 100 STAs received the Beacon frame, 50 STAs still should contend each other. Thus, uniform distribution method is helpful to distribute the entire STAs. Slide 6 September 2013 Giwon Park, LG Electronics

doc.: IEEE /1177 SubmissionSlide 7 Conclusion We want to add the following STAs behaviour into the Section –When STA detects the Link Setup Bursty is set to 1, the STA may delay the transmission of the initial link setup request frame for a random delay within the specific duration (e.g., Beacon Interval). –There is an advantage to using a random delay transmission for distributing the entire STAs which detected the Link Setup Bursty. Please adopt the proposed text in the contribution r0 or latest version. Slide 7 September 2013 Giwon Park, LG Electronics
