2. Welcome to the third teleconference of the PDED ad hoc
This group is the IEEE PDED Ad Hoc and not the IEEE EDPD Ad Hoc which is used in the calling the teleconference
PDED stands for Preamble Detect Energy Detect
PDED is an attempt to encapsulate the goal of the group …
… which is to discuss issues related to the 3GPP RAN1 request to IEEE WG to adopt an ED of -72dBm
The IEEE PDED Ad Hoc was formed in September 2016 at the Warsaw interim meeting
Andrew Myles was appointed as Chair
Andrew Myles, Cisco

3. There will be weekly teleconferences as necessary and two sessions at the plenary in San Antonio
The PDED ad hoc Chair has given notice of weekly teleconferences
Tuesday, 27 2pm PT
Tuesday, 4 2pm PT (cancelled; lack of submissions)
Tuesday, 11 2pm PT (today)
Tuesday, 18 2pm PT (cancelled; clashes with WFA meeting in Madrid)
Tuesday, 25 2pm PT
Tuesday, 1 2pm PT
The PDED ad hoc Chair has requested two session slots in San Antonio based on a draft agenda ( )
Tuesday AM2
Thursday PM1
Teleconferences and sessions will be cancelled if there is insufficient material
Andrew Myles, Cisco

4. The first task for the PDED ad hoc today is to appoint a secretary
It is important to keep proper minutes of all PDED meetings
However, it is generally not practical to Chair a meeting and take minutes at the same time
Especially without a recording 
Therefore we need a volunteer for a Secretary
Thomas Derham (Broadcom) did an excellent job in the first teleconference …
… but sharing is good! 
The rewards for the Secretary are numerous
Power over the ad hoc
Respect from your peers
… and a beverage from the Chair in San Antonio
Andrew Myles, Cisco

5. For attendance recording purposes please send an e-mail to the Chair and secretary
It would be useful to know who & how many are in attendance on this call
Please send an “I am attending PDED ad hoc” to:
<secretaries >

6. The PDED ad hoc will review the official IEEE-SA patent material for pre-PAR groups
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.
Andrew Myles, Cisco

The PDED ad hoc will operate using accepted principles of meeting etiquette
IEEE 802 is a world-wide professional technical organization
Meetings shall be conducted in an orderly and professional manner in accordance with the policies and procedures governed by the organization
Individuals shall address the “technical” content of the subject under consideration and refrain from making “personal” comments to or about others

10. The PDED ad hoc will consider a proposed agenda
Bureaucratic stuff – done!
Where are we?
Are they any other submissions today?
Will participants be willing to make future submissions?
Any objections to this agenda?
Andrew Myles, Cisco

11. Where are we?
Andrew Myles, Cisco

12. The first teleconference introduced the group and proposed at least one path forward
First teleconference details
Agenda
Minutes
First teleconference summary
Chair introduced aims of group
Chair summarised the 3GPP RAN1 request for ED of -72dBm
Chair noted that ETSI BRAN activities suggests IEEE is going to have to deal with this issue at some point
Chair suggested an evaluation mechanism based on testing/simulation
Chair made call for submissions/ideas
Andrew Myles, Cisco

13. The goal of the ad hoc is to decide on a response to 3GPP RAN1’s request for an ED of -72dBm
In Warsaw, it was agreed that the goal of PDED ad hoc is to is to discuss issues related to 3GPP RAN1’s request to IEEE WG to adopt an ED of -72dBm
The ad hoc could take one of a variety of positions
Accept the request
Maybe without reasons to 3GPP RAN1, but presumably after confirmation from TGax
Reject the request
Presumably with reasons
Propose an alternative to the request
Possibly based on previous requests to 3GPP RAN1 that they adopt
Ignore the request
Not very polite!
Andrew Myles, Cisco

14. Are they any other submissions today?
Andrew Myles, Cisco

15. No submissions have been made for today … and so it is proposed we have a brainstorming
Possible questions for brainstorming
Should IEEE adopt ED = -72dBm (presumably for 11ax)
Pro’s/con’s?
Effects on coexistence with LAA, legacy , ax?
Effects on efforts to increase frequency reuse?
Should IEEE WG continue to propose that 3GPP RAN1 adopt like ED/PD for LAA?
Likelihood that 3GPP RAN1 would actually do this?
Presumably would like LAA to detect preambles, but does care if LAA sends preambles? …
Andrew Myles, Cisco

16. No submissions have been made for today … and so it is proposed we have a brainstorming
Possible questions for brainstorming
How should IEEE 802 deal with related proposals in ETSI BRAN that the next revision of EN specify an ED = -72dBm?
Proposals?
Is there any interest in the testing/simulations proposal made during the first teleconference?
Do we agree that if we can show ED = -72dBm has an adverse effect on in any reasonable scenario that the 3GPP RAN1 request should be requested?
Who will volunteer to undertake simulations/testing? …
Andrew Myles, Cisco

17. One anonymous stakeholder (not Cisco) has provided some potential answers already
Will an ED = -72dBm cause any issues with plans for IEEE ax?
There will be issues with the Spatial Reuse features being developed in 11ax which uses variable thresholds for spatial reuse gains (it would result in diminished gains).
 Should IEEE 802 respond to the 3GPP RAN request?
 Yes, IEEE should respond to 3GPP
While based devices will need to meet relevant requirements in regulatory domains, it is undesirable for specification to adopt a lower ED threshold because it already incorporates a preamble detection mechanism that is highly sensitive (10x more sensitive than -72 dBm ED would be) and supported by billions of devices already in active use
Per above, IEEE notes that this simple mechanism can be reused by LAA devices to achieve equal and equitable sharing of the channel between all LAA and devices, including both 11ax and legacy.

18. The ad hoc will brainstorm …

19. Are participants planning to make future submissions?
