Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, 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 stuart@ok-brit.com 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 802.11 Working Group.

Month Year Month Year doc.: IEEE 802.11-yy/xxxxr0 doc.: IEEE 802.11-yy/xxxxr0 November 2007 Abstract This document introduces the channel allocation (aka channel plan) information element to assist in the channel allocation for peer-to-peer networking, or mesh networking. This presentation provides comment resolution for LB108 CID #102. Slide 2 Emily Qi (Intel Corp) et al Page 2 Emily Qi John Doe, Some Company

November 2007 Motivation In general, a Peer-2-Peer (P2P) network or a mesh network can co-exist with an infrastructure network The channel number that is selected by the P2P or mesh network can be critical to the overall WiFi network performance Guidance from the infrastructure on channel allocation for P2P or mesh networking can facilitate coordinated network planning and thus improve overall network performance: Coordinated channel planning Reduce radio interference Balance traffic load Slide 3 Emily Qi (Intel Corp) et al

Solution Introducing Channel Allocation IE November 2007 Solution Introducing Channel Allocation IE AP advertises Channel Allocation IE via Beacon and Probe Response frames The APs can advertise a frequency list that either IT recommended or the network infrastructure examined based on the interference level and traffic load Non-AP STA can get channel allocation information with or without having to associate to the infrastructure network Non-AP STA can then utilize the recommended channels for respective communication purposes Slide 4 Emily Qi (Intel Corp) et al

Peer-2-Peer Networking Month Year doc.: IEEE 802.11-yy/xxxxr0 November 2007 Channel Allocation IE Element ID Length (1 or 1+2n) Use Mode <Regulatory class, Channel number> duplet List Octets: 1 2*n This field is not present when the IE is included in the Probe Request frame. Value Description Request All when used in Probe Request; reserved when used in Probe Response and Beacon 1 Peer-2-Peer Networking 2-7 Reserved* *Note that mesh networking can be added to the Use Mode once .11s is ratified. A Channel Allocation IE includes list of <regulatory class, channel number> duplets allocated for the use mode specified in the Use Mode field Multiple Channel Allocation IEs can be used to advertise allocated channel for multiple use modes Slide 5 Emily Qi (Intel Corp) et al Emily Qi

Changes to the Management Frames November 2007 Changes to the Management Frames One or more Channel Allocation IEs can be included in the Beacon and Probe Response frame Slide 6 Emily Qi (Intel Corp) et al
