Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < 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 TAG 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 TAG.

Background
IEEE 802 and 3GPP have exchanged several liaisons since the March IEEE 802 Plenary
These liaisons can be found on the IEEE 802 web site,
In the s between 3GPP and IEEE 802 it was suggested that IEEE 802 present at a future 3GPP meeting its “Lessons Learned” on Coexistence
At the July Plenary meeting a number of people attended an meeting to discuss the 3GPP liaison and there was support at that meeting to develop a coexistence lessons learned (CLL) presentation
The IEEE 802 chair asked that it be ready for consideration at the November IEEE Plenary

Abstract
The purpose of this presentation is to provide some thoughts on an outline for the CLL presentation and to stimulate some discussion on that topic
There is interest in identifying volunteers who would like to contribute to portions of the CLL presentation
