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 IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s 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 802.11. 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 doc.: IEEE 802.11-07/0374r1 March 2007 Abstract An overview of IMT-Advanced and its relevance to IEEE 802 and 802.11, with particular emphasis on the predicted events at the March 2007 plenary session. Darwin Engwer, Nortel Networks Darwin Engwer, Nortel Networks

IMT-Advanced - Introduction March 2007 IMT-Advanced - Introduction IMT-Advanced (i.e. systems beyond IMT-2000) is a new, global, unified wireless architecture Visualizes a hierarchy of interconnected access systems Envisions new radio interfaces Mobile class targets 100 Mbps with high mobility Nomadic/ local area class targets 1 Gbps with low mobility Includes operation on new (yet to be assigned) spectrum/ bands Licensed and maybe unlicensed IEEE 802 possibilities exist in IMT-Advanced Darwin Engwer, Nortel Networks

Possible Stages of an IEEE 802 response to ITU-R WP 8F on IMT-Advanced March 2007 Possible Stages of an IEEE 802 response to ITU-R WP 8F on IMT-Advanced Stage Response Timeline 1 A high level response which indicates that IEEE 802 is working on IMT-Advanced, including a list of the working groups that are involved. Complete within IEEE 802 by end-of-week of the March 2007 plenary meeting for delivery to ITU-R WP8F prior to May 2007. 2 A more detailed response which provides specific requirements and evaluation methods (but not yet technical solutions) and includes information such as bit/ data rates, ranges, channel models, spectral efficiency, and so on. Complete within IEEE 802 by end-of-week of the November 2007 plenary meeting for delivery to ITU-R WP8F prior to Jan 2008. 3 A real proposal, which includes MAC+PHY and protocol details and specifications. Deliver to ITU-R WP 8F sometime in the 2008/2009 timeframe. 4 A final proposal for a complete standard for IMT-Advanced. This would be based on the IEEE 802 proposal from Stage 3, but may need to be modified in order to harmonize with other proposals from other SDOs. Deliver to ITU-R WP 8F sometime in the 2009/2010 timeframe. Darwin Engwer, Nortel Networks

Month Year doc.: IEEE 802.11-07/0374r1 March 2007 802.11 Suggested Actions The 802.11 Chair, and a small team of supporting experts, should attend the 802.18 Tuesday evening meeting to ensure 802.11 is included in the Stage 1 response. 802.11 should consider ratification the 802.18 output document to ITU-R WP 8F at the mid-week 802.11 plenary meeting on Wednesday morning. The 802.11 Chair, as the 802.11 voting representative in 802.18, should attend the 802.18 Thursday evening meeting to confirm approval of the stage 1 input to ITU-R WP 8F on IMT-Advanced. Review the topic of IMT-Advanced during the 802.11 closing plenary on Friday to determine if there is a need to form a team to perform more in depth investigations and craft the 802.11 specific portions of a stage 2 response to ITU-R WP 8F.
