The comment was agreed to , with resolution "To be added", but it was not added. Yes I disagree with the resolution to Initial SB comment 49 - renumber all occurrances of 802.22 to P802.22, as a published standard does not have the "P", and in most cases the references are to devices compliant with the approved IEEE Std. 802.22<year>, and there is no compliance (nor approved PICS) to an unapproved draft. Proposed Change Resolution Detail Add "Word usage" paragraph per 2009 IEEE Standards Style Manual 13.1. The reason why the Comment Resolution Committee disagrees with this comment is because: This type of indication is not present in other published standards by IEEE 802. Resolution Status Disagree Previous circulation promised to implement this, however, such "Word usage" is not present in other 802 Standards. E-mail from IEEE SA Sr. Program Manager - Michele Turner m.d.turner@ieee.org - "Comment # 1 The definition of shall, must, and should does not have to be added to the standard. The style manual gives guidance on the verbs however it is not a requirement to add them to the document." Only use P802.22 All occurrences of 802.22 should have a P in front of it. when referring to the Apurva has scanned the document and there is no such occurrence of draft standard, not the 802.22 without a P in front of it. published standard or standards-compliant devices. Slide 6 Agree in Principle Apurva N. Mody, BAE Systems July 2010 doc.: IEEE 802.22-10/0114r05 Motion for a Conditional Approval to forward the IEEE P802.22.1 Draft Standard to the IEEE SA RevCom Negative Comments from Peter Ecclestine Received During SB Re-circ #1 and the P802.22 WG Responses Disapprove Technical Submission Yes At www.secg.org, SEC 4 is not a published standard, rather it is a draft document. SECG patent policy seems circumspect http://www.secg.org/index.php?action =secg,about_patents about what the status of IPR in an unapproved SEC document are. Replace Certicom SEC 4 ECQV Implicit Certificate Scheme with TLS ECDHE ECDSA with a nonencumbered NIST Suite B ECC that conforms to FIPS-1402. This comment has been made for the section of the draft that does not Out of scope have red lines and that has not changed from Draft D6 to D7. Neither any and related comment was made during the Sponsor Ballot. So this comment is Disagree Out of Scope. The technical reasons why the Comment Resolution Committee disagreed with this comment are as follows: 1) TLS use of ECDHE or ECDSA as specified in RFC 4492 "Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS)" is not unencumbered. Implementers of that RFC require a copy of IPR disclosure that Certicom filed with IETF Secretariat. The details of this filing can be found at https://datatracker.ietf.org/ipr/1154/. IEEE 802.22 has also obtained a LOA from Certicom for similar purposes to allow implementors of 802.22.1 to make use of the ECC technology. The LOA can be found on the 802.22 Web site <www.802.22.org/22> under the Letter of Assurance section. Commentor's point/issue with regard to IPR issues is no longer valid. 2) Furthermore, the method the commentor is prescribing would result in usage of an authentication credential that is much larger in size (on the order of kB), and would not be feasible for implementation in a device with limited power for processing and limited data channel bandwidth for transmission. Performing a TLS ECDHE-ECDSA key exchange would add considerable protocol overhead. 3) Also, ECDHE-ECDSA, as specified in for TLS, is used to negotiate a session key, possibly mutual authenticated key agreement. 4) 802.22.1 use of certificates and signatures is for the purpose of authenticating messages by way of digital signatures. The techniques selected ECQV and ECPVS are the most efficient bandwidth wise and computationally. 5)The ECC implicit certificate mechanism is more appropriate to the capabilities of the radio to be used for transmitting the beacon. The implicit Slide 7 Apurva N. Mody, BAE Systems July 2010 doc.: IEEE 802.22-10/0114r05 Motion for a Conditional Approval to forward the IEEE P802.22.1 Draft Standard to the IEEE SA RevCom Negative Comments from Peter Ecclestine Received During SB Re-circ #1 and the P802.22 WG Responses Disapprove Editorial Yes "An IEEE P802.22.1/D6 device" should be ""An IEEE 802.22.1compliant device", to be correct after this standard is published. Per comment, also Introduction page iii line 3, 3.3, 7.4.5 and many places in Annex C. E-mail from IEEE SA Sr. Program Manager - Michele Turner m.d.turner@ieee.org - The letter P needs to be there in front of 802.22.1 since the standard has not been approved to go to the RevCom. The IEEE staff will remove the letter P in front of 802.22.1 before the standard goes to the RevCom. Michelle - "When referring to the technology it is ok to leave as is. However, I would suggest leaving as is without the word 'compliant', since it is already implied that it is compliant. " Agree in Principle Action: Replace "IEEE P802.22.1/D6" by "IEEE P802.22.1" Disapprove Technical Submission Yes I agree with Comment 67 on the initial ballot, "Due to the fact that there is no gap in the operation of the beacon in Figure 2 (b), the 802.22 CPE will not have an opportunity to report to the BS that there is a beacon present. That is, the beacon continuously "jams" without any respite.". I disagree with the approved comment resolution "Monique to reitterate previous rejection rationale." I suggest leaving some interval, likely more than a 802.22 WRAN frame and possibly 2 frames to solve the alignment issue, so that CPE can report the presence of the beacon. On the downstream, the CPE will receive a 6 MHz wide signal from the BS which, if interfered by a narrowband beacon signal (77 kHz), survive the beacon signal due to the narrow-band nature of the interference. On the upstream, the likelihood of the beacon creating interference at the BS is unlikely because the beacon is located close to the CPE but far from the BS. The beacon is transmitted at a much lower power than the CPE upstream. In case where the beacon is close to the BS, the BS will detect it and abide by the Policies 4, 5 and 6 as defined in the IEEE P802.22 D3 base standard in Table 251. The gist of the policies is that the CPE should not be allowed to transmit if it is not registered to the BS since it would interfere with the wireless microphones that it tries to protect, however, if the CPE is already registered with the BS, then the CPE shall send a UCS to alert the BS of the presence of the detected signal in its coverage even if it did not plan to transmit because of the potential interference from the downstream transmission. Slide 8 Disagree Apurva N. Mody, BAE Systems July 2010 doc.: IEEE 802.22-10/0114r05 Motion for a Conditional Approval to forward the IEEE P802.22.1 Draft Standard to the IEEE SA RevCom Negative Comments from Peter Ecclestine Received During SB Re-circ #1 and the P802.22 WG Responses Disapprove Editorial No Disapprove Technical Yes Disapprove Yes Editorial There are two periods at the end of the Per comment first sentence. I disagree with the resolution to Initial SB comment 1 about the NPD codewords - "The RTS codewords that were chosen have been voted by the task group and approved by the working group." - the draft is in Sponsor Ballot, it is proper to comment on the complexity of implementation, and the Comment Resolution Committee is charged with responding to comments, the response should reference the decision of the CRC. "An IEEE P802.22.1/D6 PHY" should be ""An IEEE 802.22.1-compliant PHY", to be correct after this standard is published. Agree in Principle Bring back the RTS codewords in Draft 2.0, which has been shown by simulation results that it can fulfill the requirement sufficiently, and with a very simple implementation complexity. The RTS code words were changed in Draft D4 and since then the code words have remained the same, with no technical changes made to this section. The RTS codewords that were chosen have been voted by the task group and approved by the working group because of their superior synchronization performance as compared to the other codewords that were proposed. Disagree Per comment When 802.22.1 is qualifying a device, the word "compliant" is needed. If it is a portion of the Standard like the "PHY", the word "compliant" is not needed. Agree in Principle E-mail from IEEE SA Sr. Program Manager - Michele Turner m.d.turner@ieee.org - The letter P needs to be there in front of 802.22.1 since the standard has not been approved to go to the RevCom. The IEEE staff will remove the letter P in front of 802.22.1 before the standard goes to the RevCom. Action: Replace "IEEE P802.22.1/D6 PHY" by "IEEE P802.22.1 PHY" Pile-on comment from Shulan Feng from the SB. Since then, Shulan has agreed to change his vote from Disapprove to Approve for this comment. Submission Slide 9 Apurva N. Mody, BAE Systems July 2010 doc.: IEEE 802.22-10/0114r05 Motion for a Conditional Approval to forward the IEEE P802.22.1 Draft Standard to the IEEE SA RevCom Negative Comments from Peter Ecclestine Received During SB Re-circ #1 and the P802.22 WG Responses Disapprove Technical Submission Yes The cryptographic mechanisms should use a non-encumbered NIST Suite B ECC that conforms to FIPS-140-2, rather than the Certicom SEC 4 ECQV Implicit Certificate Scheme. Replace Certicom SEC 4 ECQV Implicit Certificate Scheme with TLS ECDHE ECDSA with an unencumbered suite that can achieve FIPS140-2 certification. This comment has been made for the section of the draft that does not Out of scope have red lines and that has not changed from Draft D6 to D7. Neither any and related comment was made during the Sponsor Ballot. So this comment is Disagree Out of Scope. The technical reasons why the the Comment Resolution Committee disagreed with this comment are as follows: 1) For same reasons as response to Comment ID 3 (9218800023), We reject this comment on the technical basis. 2) ECDHE-ECDSA as specified for TLS is used to negotiate a session key, possibly mutual authenticated key agreement. 802.22.1 use of certificates and signatures is for the purpose of authenticating messages by way of digital signatures. The techniques selected ECQV and ECPVS are the most efficient bandwidth wise and computationally. 3) Suite B implementations require licensing from Certicom as well. Suite B is not unencumbered. In fact, Suite B licenses are only freely available for certain elliptic curve configurations if implementor is building a system for US federal government or US DoD. Other entities must negotiate directly with Certicom. Suite B is a suite of technology, that also implies other technologies (e.g. SHA-2, AES-256) which are not appropriate or necessary for the 802.22.1 beacon. 4) The ECC implicit certificate mechanism is more appropriate to the capabilities of the radio to be used for transmitting the beacon. The implicit certificate provides for a more compact credential so it can fit in the data channel for transmission, while not sacrificing security. In short they are providing different services and are not an even swap. Slide 10 Apurva N.

While it is useful to write a standard to test to FCC rules the document should be drafted so that other regulators with similar or identical rules can adopt the standard. Slide 25 In this section and throughout the Principle document wording like: "The Federal Communications Commission (FCC) in the United States of America has proposed to allow license-exempt devices to operate on a non-interfering basis within the portions of the TV spectrum that are not used for broadcasts or required to remain unused in order to protect broadcast stations from interference." Should be changed (in the body): "National regulators are advancing regulations that allow license-exempt devices to operate on a non-interfering basis within the portions of the TV spectrum that are not used for broadcasts or required to remain unused in order to protect broadcast stations from interference." Then in a footnote state: "This version of the standard proposes tests for the Federal Communications Commission (FCC) in the United States of America (cite section of the FCC rules). Future versions may address other comparable national regulations as they become available." The footnote alludes to "tests" that are not a part of the Draft Standard. Making the body text more internationally generic with text such as proposed (e.g. "National regulators are advancing regulations that allow license-exempt devices to operate on a non-interfering basis within the portions of the TV spectrum that are not used for broadcasts or required to remain unused in order to protect broadcast stations from interference.") seems reasonable.

Add to references: Disagree 1900.1-2008 IEEE Standard Definitions and Concepts for Dynamic Spectrum Access: Terminology Relating to Emerging Wireless Networks, System Functionality, and Spectrum Management 1900.2-2008 IEEE Recommended Practice for the Analysis of In-Band & Adjacent Band Interference and Coexistence Between Radio Systems The document P802.22.1/D6 Complete standards document Disagree must, by its very nature, reference P802.22 prior to final acceptance document P802.22 since and approval of specifications P802.22.1/D6 serves to protect contained within P802.22.1/D6. incumbent licensed devices from interference caused by devices speicified in document P802.22. Consequently, document P802.22 must be completed prior to approval of P802.22.1/D6 so that all references to any aspect of document P802.22 within P802.22.1/D6 are correct and appropriate. Slide 26 These changes are unnecessary, since P802.22.1 is intended to be a standalone standard. The scope of the P802.22.1 PAR is not limited to protecting licensed devices from only P802.22. The PAR states that completion of P802.22.1 is not dependent on the completion of any other document. (Essentially the same comment was submitted in WG ballot and rejected for the same reasons.) However, P802.22 is including an Annex which explains how to decode the P802.22.1 beacon and what to do with that information to assure protection to the licensed devices in question. Apurva N.

Specifically here and in general in the rest of the document, confusion could easily arise since what the TV channel is occupied by is often not specified. Is it TV, a beacon or a wireless mic which is on the channel under discussion? Don't ask the reader to assume which channel or signal is being talked about, when simply being specific would be quite easy and very helpful. The whole standard is about which signal is on (or thought to be on) which channel after all. I hope this helps.

Title of Annexes are not being picked up in the table of contents, making it difficult to survey the structure of the annexes. 5.3 10 Slide 27 The P802.22.1 beacon standard was developed to allow asynchronous detection of the beacon over different timeframes, for example 8-chip PN sequence can be detected asynchronously in a period of 2.8 ms and the sync burst and the index can be detected with a period of 5.1 ms. Only when additional information is desired to be decoded to further verify the presence, location, and validity of a beacon is it necessary for a system using the P802.22.1 beacon to open a longer quiet period to decode that information. The system was designed this way to minimize its impact on QoS for time/jitter sensitive services. (To further understand these sequential decoding options, see the relevant P802.22 Annex currently embodied in document 22-07-0491r6) Apurva N.

That is, the beacon continuously "jams" without any respite. Referring to the entire subclause "5.3.2 Beacon frame structure" and the associated Figure 4, the 3 MAC subframes (MSF1-MSF3) are 34 (1:2 encoded), 51, and 33 octets, respectively. We learn in 6.1.2 "Modulation rates and beacon offset location for ATSC DTV regions" that because 1/140 * the ATSC symbol rate is used, the bit rate for transmissioin is approximately 9.6091 kBaud/s = 1201.14 kbytes/s. For the 3 subframes, this translates to 28.3msec, 42.5msec, and 27.5msec, respectively. But to read MSF2 correctly, MSF1+MSF2 must be read. And to read MSF3 correctly, MSF1+MSF2+MSF3 must be read. Therefore the three windows sizes required to read the 3 frames are 28.3msec, 70.8msec, and 98.0msec (not including header). Because the integrity of the reception of the subframes relies on the CRC field, the subframes must be received in their entirety. When the 802.22 WRANs are allocating quiet periods in integral number of frames, this implies that Slide 28 I suggest leaving some interval, Disagree likely more than a 802.22 WRAN frame and possibly 2 frames to solve the alignment issue, so that CPE can report the presence of the beacon. Monique to reitterate previous rejection rationale. Please provide a Remedy. Doubling the chip rate while keeping the bit rate fixed will not shorten the MSF1. Shortening the bit duration will degrade sensitivity of the beacon. We have already determined that we cannot afford to degrade sensitivity and maintain the link margin needed to guarantee detection. The current design represents the best tradeoffs against multiple requirements. Normal detection of the TG1 beacon is for the burst and index, which requires 5.1 ms which fits in the normal 10ms 802.22 transmission frame. The actual process to decode the entier PPDU is to move out of the channel and task CPEs to revisit the channel during idle times to decode the entire beacon payload for authentication and payload. Since this is done outside of the operating channel, QoS will not be affected. (see document 22-07-0491r6 for more explaination) This comment was also rejected in WG LB#1 for the same reasons.

AAMI PC69, the standard for immunity of implantable medical devices contains an annex that provides some guideance.

Slide 38 Disagree Medical telemetry devices are now required to operate on Channel 37 on which no TVWS operation is allowed nor would a beacon ever be utilized. Other channels may be utilzied but the FCC no longer provides protection of these devices out side of the use of CH 37.

An optional characterization test is described that uses higher power levels to simulate a hand-held wireless transmitter placed much closer to the implant." The maximum power level of the beacon is 250mW; approximately 3dB greater than the level used for test.

In addition the concept of an interference event should be implimented. See the definitions, glossary and particulary Sec. 4 of 1900.2 for an explanation of these concepts. This standard should recognize interference as any measurable impact from one device to antoher, but an interference event is when such measurable impact arises to a level that the standard judges to be signfiicant, given its purpose. Harmful interference is when interference events rise to an unacceptable level. These thresholds should be clearly stated so that the reader can understand the rationale for them. There is virtually no discussion on how this standard relates to 802.22. There are just a very few references to license-exempt devices specified by P802.22, where 802.22 is just used merely as an example of a type of device that could utilize 802.22.1. But somehow, I was expecting more discussion of the relationship between this document and the base 802.22, still in progress.

This is not limited to 802.22; the 802.22.1 standard may be used to protect such devices from all unlicensed devices operating in TVWS. Apurva N.
