Agenda for PDED ad hoc teleconference on 11 October 2016 July 2010 doc.: IEEE 802.11-10/0xxxr0 Agenda for PDED ad hoc teleconference on 11 October 2016 10 Oct 2016 Authors: Name Company Phone email Andrew Myles Cisco +61 2 84461010 +61 418 656587 amyles@cisco.com Andrew Myles, Cisco Andrew Myles, Cisco

Welcome to the third teleconference of the PDED ad hoc This group is the IEEE 802.11 PDED Ad Hoc and not the IEEE 802.11 EDPD Ad Hoc which is used in the e-mail 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 802.11 WG to adopt an ED of -72dBm The IEEE 802.11 PDED Ad Hoc was formed in September 2016 at the Warsaw interim meeting Andrew Myles was appointed as Chair Andrew Myles, Cisco

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 Sep @ 2pm PT Tuesday, 4 Oct @ 2pm PT (cancelled; lack of submissions) Tuesday, 11 Oct @ 2pm PT (today) Tuesday, 18 Oct @ 2pm PT (cancelled; clashes with WFA meeting in Madrid) Tuesday, 25 Oct @ 2pm PT Tuesday, 1 Nov @ 2pm PT The PDED ad hoc Chair has requested two session slots in San Antonio based on a draft agenda (16-11-1307-00) Tuesday AM2 Thursday PM1 Teleconferences and sessions will be cancelled if there is insufficient material Andrew Myles, Cisco

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

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” email to: amyles@cisco.com <secretaries e-mail> Andrew Myles, Cisco

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

July 2010 doc.: IEEE 802.11-10/0xxxr0 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 Andrew Myles, Cisco Andrew Myles, Cisco

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

Where are we? Andrew Myles, Cisco

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 802.11 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

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 802.11 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

Are they any other submissions today? Andrew Myles, Cisco

No submissions have been made for today … and so it is proposed we have a brainstorming Possible questions for brainstorming Should IEEE 802.11 adopt ED = -72dBm (presumably for 11ax) Pro’s/con’s? Effects on coexistence with LAA, legacy 802.11, 802.11ax? Effects on efforts to increase frequency reuse? Should IEEE 802.11 WG continue to propose that 3GPP RAN1 adopt 802.11-like ED/PD for LAA? Likelihood that 3GPP RAN1 would actually do this? Presumably 802.11 would like LAA to detect 802.11 preambles, but does 802.11 care if LAA sends 802.11 preambles? … Andrew Myles, Cisco

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 301 893 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 802.11 in any reasonable scenario that the 3GPP RAN1 request should be requested? Who will volunteer to undertake simulations/testing? … Andrew Myles, Cisco

One anonymous stakeholder (not Cisco) has provided some potential answers already Will an ED = -72dBm cause any issues with plans for IEEE 802.11ax? 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 802.11-based devices will need to meet relevant requirements in regulatory domains, it is undesirable for 802.11 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 802.11 devices already in active use Per above, IEEE 802.11 notes that this simple mechanism can be reused by LAA devices to achieve equal and equitable sharing of the channel between all LAA and 802.11 devices, including both 11ax and legacy. Andrew Myles, Cisco

The ad hoc will brainstorm … Andrew Myles, Cisco

Are participants planning to make future submissions? Andrew Myles, Cisco

Are participants planning to make future submissions? Please request time on the next agenda as soon as possible Andrew Myles, Cisco
