Andrew, I just got a chance to review your latest set of slides. I prepared some comments and questions for the call. Regards, Steve ------------------------------------------------- Comments and Questions General
·
There are a number of 802.11 acronyms used in this presentation. It might be good to write out the full name the first time the acronym is used. Slide 3
·
Do we have a reference for the “evidence based approach”?
·
What is meant by a “collaborative processes for all stakeholders to have a real say in LAA coexistence mechanisms”? Slide 10
·
This slide is quite confrontational, which will most likely result in a negative reaction from members of 3GPP. I think this could be reworded to be more positive, and hence make it more constructive. Slide 11
·
We should provide some specific suggestions here. They did just invite us to the workshop, so if we want something specific beyond that we should tell them. Slide 15
·
Is the “defer” period analogous to SIFS, DIFS, etc.?
·
How do you recommend LAA reserve the channel so that Wi-Fi is aware of the reservation? Is this Wi-Fi CTS?
·
Here a picture would be worth at least 100 words, maybe 1000 words. Slide 16
·
I assume you mean that energy detection is performed during each slot in which the device is not transmitting. Slide 17
·
As I understand it the use of different lengths of defer periods in Wi-Fi is primarily for prioritization, is this really useful for coexistence between LAA and Wi-Fi? Slide 18
·
A reference would be useful here Slide 38
·
A reference would be useful here -----Original Message----- G'day all As promised the latest version is at
https://mentor.ieee.org/802.19/dcn/15/19-15-0063-04-0000-proposal-for-ieee-802-submission-to-3gpp.pptx Comments welcome ... and thanks to all those that have provided comments so far. The comments have made the document much better! :) It is still a little long but it is structured in a way that means it can be presented in a time that represents the time available Andrew -----Original Message----- From: Andrew Myles (amyles) Sent: Monday, 3 August 2015 1:11 PM To: 'yamadaakira@xxxxxxxxxxxxx';

Thanks for your input I will upload a new version later today (my time) Andrew -----Original Message----- From: Akira Yamada [mailto:yamadaakira@xxxxxxxxxxxxx] Sent: Friday, 31 July 2015 5:41 PM To: STDS-802-19@xxxxxxxxxxxxxxxxx; Andrew Myles (amyles) Subject: Re: [802.19] Request for suggestions to make 19-15-0063 better! Dear Andrew-- I appreciate your creating great presentation material for the upcoming LAA workshop. Regarding my comment in the previous teleconference on TxOP duration in slide p34, please refer to the Section 4.3.2 in TR36.889-d00. Burst transmission duration (=TxOP) in Japanese regulation is limited < 4.0ms, to enable co-existance
among several systems in 5GHz band. It looks "4ms" is the most severe rule compared with other countries.
That's why 3GPP simulates co-ex using TxOP < 4ms. Then, I would suggst change "5ms" to "4ms" in slide P34. Please let me know if there's any concern. Best Regards Akira Akira Yamada Research Laboratories, NTT DOCOMO,INC.
