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 802.19. 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 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 802.19 TAG. If you have questions, contact the IEEE Patent Committee Administrator at.http:// ieee802.org/guides/bylaws/sb-bylaws.pdfpatcom@ieee.org Date: 2006-07-18 Authors:

3. doc.: IEEE 802.19-06/xxxxr0 Submission July 2006 Tom Siep, Cambridge Silicon Radio PlcSlide 3 Coexistences scenarios Descriptions of equipment, environment, and user tasks for a wireless technology when it is required to operate in the presence of another wireless technology. Assumed operating characteristics of both technologies must be specified.

4. doc.: IEEE 802.19-06/xxxxr0 Submission July 2006 Tom Siep, Cambridge Silicon Radio PlcSlide 4 Coexistence metrics The measurements that are appropriate to perform for a specified set of scenarios. Examples might include: –Packet error rate, –maintenance of wireless links –ome quality measure

5. doc.: IEEE 802.19-06/xxxxr0 Submission July 2006 Tom Siep, Cambridge Silicon Radio PlcSlide 5 Methods for obtaining the value of the coexistence metrics Precise descriptions of the methodology required to obtain the coexistence metrics for a specific scenario or set of scenarios. This includes test equipment, environment, and required actions of the person obtaining the values for the coexistence metrics.

6. doc.: IEEE 802.19-06/xxxxr0 Submission July 2006 Tom Siep, Cambridge Silicon Radio PlcSlide 6 Levels of Scenario Descriptions General Scenario –A description of the set of networks to be considered –Example: A Pair of Unlicensed Wireless Networks – a pair of frequency static unlicensed wireless networks operating co-channel (or adjacent channel) Defined Scenario –Descriptions of equipment for a technology when it is required to operate in the presence of another wireless technology. Parameters that are constant over test scenarios are specified. –Example: Two 802.11b networks that use the same channel set Instance of a Scenario –Operating characteristics of both technologies must be specified. –Example: [details set of tests of File transfer/VoIP use cases]
