  1. Coex Ad Hoc January Taipei Agenda and Report Authors: Date: 2008-01-10 Eldad Perahia (Intel)

  2. Abstract Coex Ad Hoc in November Atlanta agenda and report regarding comment resolution of LB115 (802.11n), including straw polls Eldad Perahia (Intel)

  3. Highlights of the IEEE-SA Standards Board Bylaws on Patents in Standards • Participants have a duty to tell the IEEE if they know (based on personal awareness) of potentially Essential Patent Claims they or their employer own • Participants are encouraged to tell the IEEE if they know of potentially Essential Patent Claims owned by others • This encouragement is particularly strong as the third party may not be a participant in the standards process • Working Group required to request assurance • Early assurance is encouraged • Terms of assurance shall be either: • Reasonable and nondiscriminatory, with or without monetary compensation; or, • A statement of non-assertion of patent rights • Assurances • Shall be provided on the IEEE-SA Standards Board approved LOA form • May optionally include not-to-exceed rates, terms, and conditions • Shall not be circumvented through sale or transfer of patents • Shall be brought to the attention of any future assignees or transferees • Shall apply to Affiliates unless explicitly excluded • Are irrevocable once submitted and accepted • Shall be supplemented if Submitter becomes aware of other potential Essential Patent Claims • A “Blanket Letter of Assurance” may be provided at the option of the patent holder • A patent holder has no duty to perform a patent search • Full policy available at http://standards.ieee.org/guides/bylaws/sect6-7.html#6 1 Eldad Perahia (Intel)

  4. IEEE-SA Standards Board Bylaws on Patents in Standards 6.2 Policy IEEE standards may be drafted in terms that include the use of Essential Patent Claims. If the IEEE receives notice that a [Proposed] IEEE Standard may require the use of a potential Essential Patent Claim, the IEEE shall request licensing assurance, on the IEEE Standards Board approved Letter of Assurance form, from the patent holder or patent applicant. The IEEE shall request this assurance without coercion. The Submitter of the Letter of Assurance may, after Reasonable and Good Faith Inquiry, indicate it is not aware of any Patent Claims that the Submitter may own, control, or have the ability to license that might be or become Essential Patent Claims. If the patent holder or patent applicant provides an assurance, it should do so as soon as reasonably feasible in the standards development process. This assurance shall be provided prior to the Standards Board’s approval of the standard. This assurance shall be provided prior to a reaffirmation if the IEEE receives notice of a potential Essential Patent Claim after the standard’s approval or a prior reaffirmation. An asserted potential Essential Patent Claim for which an assurance cannot be obtained (e.g., a Letter of Assurance is not provided or the Letter of Assurance indicates that assurance is not being provided) shall be referred to the Patent Committee. A Letter of Assurance shall be either: a) A general disclaimer to the effect that the Submitter without conditions will not enforce any present or future Essential Patent Claims against any person or entity making, using, selling, offering to sell, importing, distributing, or implementing a compliant implementation of the standard; or b) A statement that a license for a compliant implementation of the standard will be made available to an unrestricted number of applicants on a worldwide basis without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination. At its sole option, the Submitter may provide with its assurance any of the following: (i) a not-to-exceed license fee or rate commitment, (ii) a sample license agreement, or (iii) one or more material licensing terms. 2 Eldad Perahia (Intel)

  5. IEEE-SA Standards Board Bylaws on Patents in Standards Copies of an Accepted LOA may be provided to the working group, but shall not be discussed, at any standards working group meeting. The Submitter and all Affiliates (other than those Affiliates excluded in a Letter of Assurance) shall not assign or otherwise transfer any rights in any Essential Patent Claims that are the subject of such Letter of Assurance that they hold, control, or have the ability to license with the intent of circumventing or negating any of the representations and commitments made in such Letter of Assurance. The Submitter of a Letter of Assurance shall agree (a) to provide notice of a Letter of Assurance either through a Statement of Encumbrance or by binding any assignee or transferee to the terms of such Letter of Assurance; and (b) to require its assignee or transferee to (i) agree to similarly provide such notice and (ii) to bind its assignees or transferees to agree to provide such notice as described in (a) and (b). This assurance shall apply to the Submitter and its Affiliates except those Affiliates the Submitter specifically excludes on the relevant Letter of Assurance. If, after providing a Letter of Assurance to the IEEE, the Submitter becomes aware of additional Patent Claim(s) not already covered by an existing Letter of Assurance that are owned, controlled, or licensable by the Submitter that may be or become Essential Patent Claim(s) for the same IEEE Standard but are not the subject of an existing Letter of Assurance, then such Submitter shall submit a Letter of Assurance stating its position regarding enforcement or licensing of such Patent Claims. For the purposes of this commitment, the Submitter is deemed to be aware if any of the following individuals who are from, employed by, or otherwise represent the Submitter have personal knowledge of additional potential Essential Patent Claims, owned or controlled by the Submitter, related to a [Proposed] IEEE Standard and not already the subject of a previously submitted Letter of Assurance: (a) past or present participants in the development of the [Proposed] IEEE Standard, or (b) the individual executing the previously submitted Letter of Assurance. 3 Eldad Perahia (Intel)

  6. IEEE-SA Standards Board Bylaws on Patents in Standards The assurance is irrevocable once submitted and accepted and shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal. The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of those Patent Claims, or for determining whether any licensing terms or conditions are reasonable or non-discriminatory. Nothing in this policy shall be interpreted as giving rise to a duty to conduct a patent search. No license is implied by the submission of a Letter of Assurance. In order for IEEE’s patent policy to function efficiently, individuals participating in the standards development process: (a) shall inform the IEEE (or cause the IEEE to be informed) of the holder of any potential Essential Patent Claims of which they are personally aware and that are not already the subject of an existing Letter of Assurance, owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents; and (b) should inform the IEEE (or cause the IEEE to be informed) of any other holders of such potential Essential Patent Claims that are not already the subject of an existing Letter of Assurance. 4 Eldad Perahia (Intel)

  7. Other Guidelines for IEEE WG Meetings • All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. • Don’t discuss the interpretation, validity, or essentiality of patents/patent claims. • Don’t discuss specific license rates, terms, or conditions. • Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings. • Technical considerations remain primary focus • Don’t discuss fixing product prices, allocation of customers, or dividing sales markets. • Don’t discuss the status or substance of ongoing or threatened litigation. • Don’t be silent if inappropriate topics are discussed… do formally object. --------------------------------------------------------------- If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at patcom@ieee.org or visit http://standards.ieee.org/board/pat/index.html See IEEE-SA Standards Board Operations Manual, clause 5.3.10 and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

There is already such a note in 9.13.4 • Eldad: since the name of the parameter includes “convolutional” will we get someone asking what the value is with LDPC? • No objection to accepting submission as resolution to CIDs and bringing to motion Eldad Perahia (Intel)

  16. 07/2990 • Resolves Editor CID 5875, needs to be transferred to Coex • No objections to resolution • CID 5876 • Bruce: question regarding “any channel width” phrase, any issue with limiting to 40MHz • Tomo: text in 7.3.1.24 is the same type of wording • Eldad: “any channel width” is limited to Supported Channel Width Set • Everyone happy with current text, no objection with resolution • CID 5841 – no objections • CID 5359 – no objections • CID 5829 – no objections • CID 5109 – no objections • CID 5736 – no objections • CID 5737 – no objections • CID 5739 • Adrian: Change the may to can in the second edit instruction • no objections to resolution with changes • CID 5740 – no objections Eldad Perahia (Intel)

  17. 07/2990 continued • CID 5741 • Adrian: can we make the second two sentences (in the first editor instruction) into a note, since they are informative. Limits comments. • No objections to change • No objections to resolution with changes • CID 5830 – no objections • CID 5831 • Solomon: address the fact that traffic mixes are unknown in the rejection • No objections to resolution with changes • CID 5360 • Bruce: some grammar changes • Eldad: may needs to be changed to may • No objections to resolution with changes • CID 5744 – no objections • CID 5358 – no objections • CID 5745 – no objections • No objection to accepting r1 of submission as resolution to CIDs and bringing to motion Eldad Perahia (Intel)

  18. 08/0064 • CID 5796 • No intent to change meaning, just clarifications • Bruce: grammar corrections • No objection to accepting r1 of submission as resolution to CID and bringing to motion Eldad Perahia (Intel)

  19. 07/2742 • Reviewed changes based on conference call discussion • CID 5045, 5485, 5424, 5447, 5850 • CID 5850 • Still have issue with changing channel width in IBSS when there is no DFS owner, changed color to green • Solomon: we have the same issue with changing channel in IBSS • Matt: general issue of dynamic parameters in IBSS when no one is in charge (see CID 5276 in MAC in 07/2999) • Adrian: might get a mix of DFS and non-DFS capable devices • Issue is held open by CID 5872 • CID 5117 • Adrian: making assertion the operation is fair, its never been tested. But we don’t necessary care if its fair. • Matt: changed “fair” to “sufficiently adequate user experience” • Allert: is this a “counter” • Luke is ok with “counter” • No further objection • CID 5485 • Added rejection resolution text since conference call • No objections Eldad Perahia (Intel)

  20. 07/2742 continued • CID 5851 • Matt: Term BSS includes IBSS • Matt: Changed IDO STA to FC HT STA 17 to broaden the language to allow a non-DFS owner to start IBSS, but changes will be un-done since DFS 802.11-2007 rules in 11.9.7.2 state a STA starting an IBSS in DFS band shall be the DFS owner. • Changed to reject • No objections • CID 5852, 5854 – no objection • CID 5180 • Lots of discussion on whether to change “5 GHz” to “not 2.4GHz”, points raised: • There was only 2.4 & 5 GHz at time of 11n starting, now we have 11y • We have only thought about 2.4 & 5 GHz we don’t know what the 40 MHz coex issues would be in other bands • Tomo: FC 17 restricts to 5 GHz, which is in many other places. Changes only to 11.9.8.3 would not be enough • To make all the changes to draft would be complicated, reject and leave for next task group • Allert: change to FC HT AP restricts to HT device in “other band” • Since the change was un-done, “FC HT” is not added anymore • No objection to rejection • Changes based on 5180 un-done Eldad Perahia (Intel)

  21. 07/2742 continued • CID 5853, 5855 • Changed to reject, refer to 5851 • No objections • CID 5856, 5858 • No objections • CID 5857 • Changed “HT AP or IDO STA” to “HT AP or IDO STA that is also an HT STA” in 11.9.8.3 • No objections • CID 5859 - no objections • CID 5030 • Resolution text modified to indicate changes based on 2.4GHz language and 5 GHz language • No objections • CID 5860 • Changed to reject, refer to 5851 • No objections Eldad Perahia (Intel)

  22. 07/2742 continued • CID 5861 • Added reference to CID 5851 in resolution • No objections • CID 5862 – no objections • CID 5031 • Added resolution text stating that the use of scan results is implicit on existing rules • Tomo: is there a reference to rules? • Matt: anything that causes a trigger event must follow the trigger • Continue with CID 5808 tomorrow Eldad Perahia (Intel)

  23. Status at end of Friday Jan 11 • Unresolved CIDs (not approved by ad hoc to be motioned in TGn): 144 • 20/40 group: 103 • CCA: 16 • GF: 3 • Protection: 2 • Reorg: 8 • L-SIG TXOP: 11 • Misc: 1 • PCO: 0 • CIDs in 07/2724 w/ no objections: 31 • CIDs still needing review: 113 Eldad Perahia (Intel)
