1 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 1 Extended Channel Switch Response Notice: This document has been prepared to assist IEEE It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEEs name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEEs sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE Working Group. If you have questions, contact the IEEE Patent Committee Administrator at.http:// 2006-NOV-16

2 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 2 Introduction Extended Channel Switch Response proposal: simple response frame added to address TGv objective #2000, Dynamic Channel Selection: TGv shall support Dynamic Channel Selection, to allow STAs to avoid interference. Solution shall be able to change the operating channel (and/or band) for the entire BSS during live system operation and be done seamlessly with no intermittent loss of connectivity from the perspective of an associated STA. Solution shall not define algorithm for channel selection. Normative Text in x-000v

3 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 3 Simple Addition Extended Channel Switch Announcement in beacons and in standalone frame adopted at last meeting. Spray and pray solution w/o coordination needed for seamless service transitions to new channel. Simple short Extended Channel Switch Response frame adds missing feedback from STA needed for AP to select best new channel. Standard Request/Response exchange Is an optional feature not used when continuity of service for individual STAs is important.

4 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 4 Normative Text Review: 06/1485 Minimal additions to 11v draft: New Channel Switch Response frame added to provide response code and optional alternative channel number. Optional Dialog Token added to Extended Channel Switch Announcement frame to invoke response Simple procedure requiring receiving STA to send response before channel switch Walkthrough Normative Text Document: v-NormText_Extended_Channel_Switch_Response.doc

5 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 5 Conclusions Simple implementation Provides seamless, acknowledged channel required for QOS services. More work needed on normative text details and response codes. Questions & Discussion

6 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 6 STRAW POLL Do you support the addition of an Extended Channel Switch Response to improve seamless channel switching? YES _______ NO _______ ABSTAIN _______

7 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 7 BACKUP SLIDES FOLLOW These charts are provided for your further information

8 doc: IEEE /0388r5November 2006 Submission Kwak, Rudolf, InterDigital 8 Channel Switch Response Sent by STA in response to Channel Switch request May contain alternate channel suggestion based on STA local conditions. Contains: Channel spec, as usual Response code which is a function of the request type
