                            Affiliation Policy
 • Requirement to declare affiliation at all standards
   development meetings and recorded in the minutes
    – Affiliation not necessarily same as employer
    – Declaration requirement may be familiar to some 802 WGs, though
       WG declaration process may evolve
 • 11. What if I refuse to disclose my affiliation?
       – As outlined in IEEE-SA governance documents, you will lose certain rights.
         In a working group where voting rights are gained through attendance, no
         attendance credit will be granted if affiliation isn’t declared. Similarly, voting
         rights are to be removed if affiliation isn’t declared.
 • Affiliation declaration will be added to Sponsor ballot

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

             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

              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

      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.

             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.

      beginning of the conference call – see the question located on slide 12
 •    Submissions related to CIDs
       – 11-08-0132-00 duration setting – Yuichi – reviewed but not actioned
       – 11-07-2942-01-000n-lb115-mac-ht-dls.doc – Liwen/MattF
               •   Reviewed during January interim, outcome pending investigation regarding legacy STA behavior
       –     11-08-xxxx Security – MattS
       –     11-08-xxxx STBC – Menzo
       –     CID 5188 – MAC General – undetected error – Adrian
               •   Worked with Brian – result of probability of undetected error depends on assumptions – if no mid-packet collisions, then
                   Adrian believes that our amendment meets the requirements – if a collision starts during the MAC header, then the
                   specification in question might not be met – in that case, the failure rate rises to the 2e-32 FCS rate. With a good MAC header,
                   various header fields end up qualifying the reception
               •   Mid-packet collision rate of less than 10e-4 will give an acceptable result
               •   Definition of a mid-packet interference event: event that is long enough duration to exceed the correcting capability of the
                   decoder – only likely with another transmission
               •   Not enough material yet available to craft a resolution to CID 5188
               •   Adrian has heard that 802 PAR includes an exclusion regarding PER – not document 1991-58, which provides for an exception
                   for an increased MSDU loss-rate
               •   Adrian notes that 802.11a is also 10e-4 from meeting the requirement, based on the same argument that causes us to fail (i.e.
                   midpacket collision), so MPDU length change by TGn is insignificant
 •    Recycled CIDs
 •    Other CIDs
       –     Resolved an additional 5 CIDs from the STBC group

 •
 •    CID 5116
 •    CIDPageClauseCommentProposed Change511696.018During the development leading up to D2.0, there were attempts to analyze the security
      implications of the text (see MAC Ad Hoc minutes at Melbourne ad hoc). However, it is not evident such efforts are repeated for D3.0.Analyze the
      security implications of the text and address any weaknesses.
 •    Proposed Resolution
 •    Counter (accept in principle). A security review was undertaken and the results documented in 11-08/0009r2. This review identified one problem
      not associated with any other comment related to the protection of the “A-MSDU Present” field and subsequent discussion in the MAC ad-hoc
      identified a solution to this problem.
 •    TGn Editor: Make editorial changes shown in 11-08/0009r2.

 •    ---------
 •    and:
 •    Editing Instructions
 •    TGn Editor: Change 11.18 as follows:
 •    11.18 RSNA A-MSDU procedures (#289)
 •    When dot11RSNAEnabled is TRUE, a STA indicates support for PP (payload protected) A-MSDU or SPP
 •    (signaling and payload protected) A-MSDU during association or reassociation. On either association or reassociation, the associating STA and its
      peer STA both determine and maintain a record of whether an encrypted
 •    A-MSDU sent to its peer is to be a PP A-MSDU or an SPP A-MSDU based on the value of the SPP
 •    A-MSDU Capable and SPP A-MSDU Required subfields of the RSN Capabilities field of the RSN information
 •    element (see 7.3.2.25.3 (RSN capabilities (#289))).
 •    The SME of an RSNA and HT-capable STA may choose to associate with an RSNA STA that has the SPP
 •    A-MSDU Capable subfield set to either 1 or 0, and the SPP A-MSDU Required field set to either 1 or 0.
 •    Table 11-8a (A-MSDU STA Behavior for RSNA associations) defines both transmit and receive behavior related to the transmission and reception of
      individually addressed A-MSDUs of a first STA (STA1) that has successfully negotiated an HT and RSNA (re)association with a second STA
      (STA2). Reception and transmission of A-MSDUs on non-RSNA associations is unaffected by the values of the SPP A-MSDU Capable and SPP A-
      MSDU Required fields.
 •    Group addressed A-MSDUs shall not be protected (i.e., are always transmitted without encryption).

         –        11-07-2745-01 – MattF – Mac MGMT – reviewed, resolved some comments, will be revised for IBSS issue – group prefers approach that restricts
                  IBSS to not changing dynamic values for the life of the IBSS and explicitly naming which values are per-STA and which are per-IBSS, use table in
                  HT Info element IBSS column as a start

                     •      Straw polls on proposed solutions from 5899 – a: 6,1 b: 2,4 c: 1,3 d: 6,0
                     •      It is suggested that while solution d would be nice, it is asked if anyone in the room is aware of anyone that could create the text for such a solution within the
                            time frame remaining for LB115 comment resolution and the answer is no, so CID 5899 is rejected with one vote against the rejection.

 There is a      change the     MAC: 2008-01-11 10:17:55Z Reject - as follows:
    potential       order of
    DOS             "block ack     It is accepted that a denial of service (DoS) attack
                                   exists in which a forger generates Data MPDUs with
    attack          reordering"    an arbitrary SN, forcing a STA to consider validly sent
    identified      and "MPDU      MPDUs to be outside its BA window. The proposed
    on the          decryption     change correctly addresses this attack.
    receiving       and            However, the same DoS attack also exists as a replay
    side of         intergrity"    attack. In this case the hacker captures a single
    the data                           encrypted Data MPDU addressed to the victim. It then
    plane                              replays this MPDU as much as it wants to, while
                                       changing its SN field. Because the SN field is not part
                                       of the AAD, this MPDU continues to pass through the
                                       integrity check logic, and will still cause the Block Ack
                                       receiver buffer to be flushed. Eventually the
                                       problematic MPDU reaches the replay logic, where it
                                       is discarded - but not before the damage to the
                                       BlockAck buffer has been done.
                                       Given that the proposed solution does not fully
                                       addfress the attack on the block ack reordering buffer.

                            CID 5899 discussion

 • In addition to the information found in the proposed resolution the
   following point was disccussed during the adhoc:
       – The sender of frames (the originator with respect to the Block Ack
         agreement) is able to determine that an attack has occurred
             • If a malicious BAR is sent (with an out-of-window SN), then the recipient
               responds with a BA that contains the SSN of the malicious BAR
                 – The originator sees a BA SSN that does not correspond to the originator’s current
                   concept of SSN and can establish that an attack has occurred
             • If a malicious packet is sent, (with an out-of-window SN), then the recipient
               responds with a BA that contains the SSN of the malicious BAR
                 – The originator sees a BA SSN that does not correspond to the originator’s current
                   concept of SSN and can establish that an attack has occurred
