doc.: IEEE 802.19-05/0023r0 Submission July 2005 Steve Shellhammer, Qualcomm Inc.Slide 1 Questions to the Contention-based Protocol (CBP) Study Group Notice: This document has been prepared to assist IEEE 802.19. 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 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, 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:// firstname.lastname@example.org Date: 2005-07-19 Authors:
doc.: IEEE 802.19-05/0023r0 Submission July 2005 Steve Shellhammer, Qualcomm Inc.Slide 2 Questions to the CBP SG The 802.19 TAG is interesting in understanding the scope of the CBP Project The TAG has several questions to the study group to help us understand the scope of the project These questions only related to how the FCC rules are written today.
doc.: IEEE 802.19-05/0023r0 Submission July 2005 Steve Shellhammer, Qualcomm Inc.Slide 3 Questions to CBP SG What 802 wireless working groups have interest in operating in the 3650 – 3700 MHz band? –802.11 (serious about amending 802.11 to meet the FCC rules) –802.16 (have activities underway for techniques that would may meet the FCC rules e.g. 16h) –The FCC will expect whatever is approved will be able to share with current and future primary government and non-government users in the band –The FCC will expect whatever is approved needs to be able to share with previously approved secondary systems
doc.: IEEE 802.19-05/0023r0 Submission July 2005 Steve Shellhammer, Qualcomm Inc.Slide 4 Questions to CBP SG Does the CBP group plan to develop a spectrum sharing technique to enable sharing between multiple 802 wireless systems? –The current plan is not to develop such a technique –Such a technique may add significant cost –Is developing such a system worth the effort? –There may or may not be a broad market appeal for a broader project, for a 50 MHz band.
doc.: IEEE 802.19-05/0023r0 Submission July 2005 Steve Shellhammer, Qualcomm Inc.Slide 5 Questions to CBP SG Does the CBP SG see multiple working groups developing their own contention based protocols for operating in this band? –The CBP PAR would enable an extension of 11a or possibly 11n, other. –16h could (be made to) use this band
doc.: IEEE 802.19-05/0023r0 Submission July 2005 Steve Shellhammer, Qualcomm Inc.Slide 6 Possible Views on the Scope of the Project Option 1 – Amend 802.11 to enable it to operate in the band and meet the FCC rules Option 2 – Develop a spectrum sharing technique (i.e. CBP) that enables multiple 802 wireless standards to share the band Option 3 – Does the group plan to develop an out-of- band link to resolve a conflict? Which approach is the CBP group planning to take? –Option 1 Is there value in pursing Option 2? –Maybe not for this band since it is only 50 MHz –However, since it is only 50 MHz, there is a need for a spectrum sharing technique
