November 2009 doc.: IEEE 802.11-09/1220r1 WG11 Comments on 802-22 PARs submitted Nov 2009 Date: 2009-11-17 Authors: Name Affiliations Address Phone email Jon Rosdahl CSR Highland, UT +1-801-492-4023 jrosdahl@ieee.org Submission Slide 1 Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 Abstract This Submission contains the comments to 802.22 on the two PARs that are under consideration for the November Plenary. There was a motion to forward these comments to 802.22, each motion passed 12-0-0 for sending these comments from 802.11. There are 2 sets of comments, one for each PAR. 802.22 slides 3-7 802.22.3 slides 8-11 Submission Slide 2 Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 802.22 PAR modification to clarifying scope, PAR and 5C • Item 1: Doc 11-09/1105r1 – submission that has some discussion on the rational for changing the scope. • Item 2: Problem: Dates for completion are not realistic. The dates need to be corrected (we suggest that the dates of Start Sponsor 12-2012 and RevCom 12-2013 would be more realistic/acceptable.) • Item 3: the form presented was not the correct PAR form. The PAR modification form should be used. Submission Slide 3 Jon Rosdahl, CSR November Month Year2009 doc.: IEEE 802.11-09/1220r1 Questions and Responses to 802.11 • Question 1: Doc. 11-09/1106 discusses possible issues with the PAR and 5C submitted by Peter E • Response: Accept document • Proposed Resolution – See document IEEE 802.22. 09-235 addressing the questions and comments in doc.11-09-1106 Submission Slide 4 Wendong Jon Rosdahl, Hu, STM CSR November 2009 doc.: IEEE 802.11-09/1220r1 Questions and Responses to 802.11 • Question: Problem- Dates for completion are not realistic. The dates need to be corrected (we suggest that the dates of Start Sponsor 12-2012 and RevCom 12-2013 would be more realistic/acceptable.) Response: Reject comment Explanation No significant effort is anticipated for addressing the requirements in the modified PAR. The date of initial sponsor ballot is expected to be 072010 and Revcom is 07-2011. • Question - The form presented was not the correct PAR form. The PAR modification form should be used.

The Study Group has therefore concluded that placing the project in a new WorkingGroup is the most efficient approach..” • 5c: Distinct Identity A – Issue 6: This text fails to distinguish among 802.16h, which will be an approved amendment in early 2010, and 802.22 and the efforts proposed in the 802.22.3 PAR. Add distinctions between each of the three. Be aware that 802.16h clause 6.3.2.3.86 does report DTV, wireless microphones and other licensed users.

Table – Issue 5: Page 8 of 11-09-1106r0 shows several errors in the table and in the explanation notes. • Please correct as noted in 11-09/1106r0. Response; Accept comment Proposed Resolution Necessary corrections/changes have been made in the revised PAR/5C document. Rebuttal -1: The Table is still incorrect. 802.16h range should be from 0 to 11GHz. (still shows 2GHz as a lower limit which is incorrect). Submission Slide 19 Wendong Hu, STMicroelectronics Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 802.22.3 (3) • Technical Feasibility – Issue 6 : the statements are very broad, and in some cases not accurate…” Existing 802 wireless standards in other bands (e.g. 802.11h) have demonstrated that detection and avoidance of operation in spectrum occupied by licensed users is technically feasible.” The 802.11h does not do detect and avoid (DAA) it only specified DFS and TPC. – Issue 7: The statements should address the “demonstrated” technology that show the technical feasibility. – Issue 8: The addition of “Scalable” as the main focus, should be addressed in the 5C to show the distinct difference from the base 22 standard. – Issue 9 (to be renumbered as #1): If 802.22.3 is an extension of 802.22, and creating a “Scalable” extension of the standard, then this should be an amendment. The Amendment should be created after the standard is approved to allow a consistent target for the amendment to modify. Submission Slide 20 Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 Questions and Responses to 802.11 • Question: Technical Feasibility – the statements are very broad, and in some cases not accurate…” Existing 802 wireless standards in other bands (e.g. 802.11h) have demonstrated that detection and avoidance of operation in spectrum occupied by licensed users is technically feasible.” The 802.11h does not do detect and avoid (DAA) it only specified DFS and TPC. Response: Accept comment Proposed Resolution The statement was modified appropriately – The statements should address the “demonstrated” technology that show the technical feasibility. Response: Accept comment Proposed Resolution The statement was modified to provide the “demonstrated” technologies (by cited examples) that can be leveraged by the proposed 802.22.3 Submission Slide 21 Wendong Hu, STMicroelectronics Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 Rebuttal - 2 • Rebuttal There has not been any demonstration of independently operated scalable operation in unlicensed bands. • Submission Slide 22 Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 Questions and Responses to 802.11 • Question: Technical Feasibility (continued) – Issue 8: The addition of “Scalable” as the main focus, should be addressed in the 5C to show the distinct difference from the base 22 standard. Response: Accept comment Proposed Resolution The distinct different from the base 22 standard of the 802.22.3 is provided in a revised text. – Issue 9 (to be renumbered as #1): If 802.22.3 is an extension of 802.22, and creating a “Scalable” extension of the standard, then this should be an amendment. The Amendment should be created after the standard is approved to allow a consistent target for the amendment to modify. Response: Reject Comment “Scalable” is not an extension of 802.22. It addresses a different area of TVWS operation of WRAN as opposed to that of 802.22, and does not depend on the completion of 802.22 project. Proposed Clarification Propose a clarification by changing the wording for the purpose to: “The purpose of this standard is to specify scalable wireless regional area network (WRAN) operations in the TVWS, enabling WRAN deployments and communications in flexible network topologies and range, with greater network coverage, offering a variety of in-door and out-door network services. Submission Slide 23 Wendong Hu, STMicroelectronics Jon Rosdahl, CSR November 2009 doc.: IEEE 802.11-09/1220r1 Rebuttal - 3 • Rebuttal – You should not have a new PAR for changes to an existing PAR. If 802.22 baseline par was never finished, would it make a difference to 802.22.3? The Fixed and portable mechanisms in 802.22 would not be available, then what are you “scaling”. • We still believe that the PAR type should be an Amendment. It is an extension of the base standard. • Integration of the new standard into the old standard sounds like an amendment rather than a new standard.
