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 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 802.19. 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 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 <shellhammer@ieee.org> 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 <patcom@ieee.org>. Hyunduk Kang, ETRI Steve Shellhammer, Qualcomm

Interest Group: Coexistence on Unlicensed Frequency Bands November 2014 Interest Group: Coexistence on Unlicensed Frequency Bands 802.19 WG formed an interest group on coexistence in unlicensed bands at the March 2014 plenary meeting 19-14/0032r0: March 2014 WG Minutes The 1st face-to-face meeting held on July 2014. The CUB IG held 7 conference calls up to now The November 2014 plenary meeting is the 3rd face-to-face meeting. Hyunduk Kang, ETRI

November 2014 Purpose of IG CUB To explore coexistence issues in unlicensed frequency bands Current situations Potential problems To discuss possible solutions to solve coexistence problems A possible common coexistence solution which could be adopted to different systems To decide main topic of work of Study Group Hyunduk Kang, ETRI
