Instructions for the WG Chair
The IEEE-SA strongly recommends that at each WG meeting the chair or a designee:
–
–
Show slides #1 through #4 of this presentation
Advise the WG attendees that:
• The IEEE’s patent policy is consistent with the ANSI patent policy and is described in Clause 6 of the
IEEE-SA Standards Board Bylaws;
• Early identification of patent claims which may be essential for the use of standards under
development is strongly encouraged;
• There may be Essential Patent Claims of which the IEEE is not aware. Additionally, neither the IEEE,
the WG, nor the WG chair can ensure the accuracy or completeness of any assurance or whether any
such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under
development.
–
Instruct the WG Secretary to record in the minutes of the relevant WG meeting:
• That the foregoing information was provided and that slides 1 through 4 (and this slide 0, if applicable)
were shown;
• That the chair or designee provided an opportunity for participants to identify patent claim(s)/patent
application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the
participant is personally aware and that may be essential for the use of that standard
• Any responses that were given, specifically the patent claim(s)/patent application claim(s) and/or the
holder of the patent claim(s)/patent application claim(s) that were identified (if any) and by whom.
–
The WG Chair shall ensure that a request is made to any identified holders of potential essential patent
claim(s) to complete and submit a Letter of Assurance.
It is recommended that the WG chair review the guidance in IEEE-SA Standards Board Operations Manual
6.3.5 and in FAQs 12 and 12a on inclusion of potential Essential Patent Claims by incorporation or by
reference.
–
Note: WG includes Working Groups, Task Groups, and other standards-developing committees with a PAR approved by the
IEEE-SA Standards Board.

Participants, Patents, and Duty to Inform
All participants in this meeting have certain obligations under the IEEE-SA Patent Policy.
Participants:
– “Shall inform the IEEE (or cause the IEEE to be informed)” of the identity of each
“holder of any potential Essential Patent Claims of which they are personally aware”
if the claims are owned or controlled by the participant or the entity the participant
is from, employed by, or otherwise represents
• “Personal awareness” means that the participant “is personally aware that the holder may
have a potential Essential Patent Claim,” even if the participant is not personally aware of
the specific patents or patent claims
– “Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any
other holders of such potential Essential Patent Claims” (that is, third parties that
are not affiliated with the participant, with the participant’s employer, or with
anyone else that the participant is from or otherwise represents)
– The above does not apply if the patent claim is already the subject of an Accepted
Letter of Assurance that applies to the proposed standard(s) under consideration by
this group
Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2
• Early identification of holders of potential Essential Patent Claims is strongly encouraged
• No duty to perform a patent search

Call for Potentially Essential Patents
• If anyone in this meeting is personally aware of the holder of any
patent claims that are potentially essential to implementation of
the proposed standard(s) under consideration by this group and
that are not already the subject of an Accepted Letter of
Assurance:
– Either speak up now or
– Provide the chair of this group with the identity of the holder(s) of any and all such
claims as soon as possible or
– Cause an LOA to be submitted

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 or engage in the fixing of product prices, allocation of
customers, or division of 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.

PHY Motion #5
• Move to add to the TG Specification Framework document:
• The HE-LTF shall adopt a structure of using P matrix in the data
tones as in 11ac.
• In the data tones, every space-time stream is spread over all HELTF symbols by one row of the P matrix as defined in 11ac.
Different space-time streams use different rows in P matrix.

MAC Motion #1
Move to add the following to the TG SFD:
• x.y.z The spec shall define a multi-STA BA frame by using the Multi-TID
BlockAck frame format with the following changes:
– Add an indication that the frame is a multi-STA BA (TBD)
– Each BA Information field can be addressed to different STAs
• B0-B10 of the Per TID Info field carry a (Partial) AID identifying the intended receiver of
the BA Information field
B0-B10= AID

MAC Motion #2
Do you agree to add the following to the TG SFD:
• x.y.z The spec shall define a signaling in the Multi-STA BA frame that can indicate
an ACK, as follows:
–
•
If B11 in the per-TID info field is set, then the BlockAck bitmap and the SC subfields in the
BA Info field are not present and this BA Info field indicates an ACK for the STA with AID
indicated in the per-TID info field
Instruction to the Editor: replace the Multi-STA BA figure from motion 1
with the following
B0-B10= AID
B11= ACK/BA
