2. In May, we agreed to create a study group on EHT
During the May meeting, we proposed the creation of a study group to increase peak throughput with the following features: 320MHz, multiband aggregation and 16 spatial streams.
Document 789r10 ( 0wng-extreme-throughput pptx) is describing the proposed scope.
A strawpoll was run in the WNG session (96 Y, 1 N, xx A):
Do you agree to start a study group to define new features of on bands between 1 and GHz with the primary objective to increase peak throughput with the following candidate features: 320MHz bandwidth, multiband aggregation and operation, and 16 spatial streams.  In addition,
The study group will discuss high throughput applications such as video-over-WLAN, AR and VR
The study group may discuss additional objectives and features. Final set of features shall be determined within 6-months, which should be also the maximum duration of study group.
The study group may define procedural enhancements to make standards development more efficient and scalable.

3. We motioned the creation of a TIG to initiate discussion in July
A TIG was then created to initiate discussion (as a study group can not be created during interims)
Approve formation of an XT TIG to initiate discussion on new features for bands between 1 and GHz:
with the primary objective to increase peak throughput
candidate features include but are not limited to: 320 MHz bandwidth, multiband aggregation and operation, and 16 spatial streams, as described in
To support high throughput applications such as video-over-WLAN, AR and VR

4. TIG discussions during July meeting
This TIG is a way to initiate study group discussion during the July meeting, with the promise that it will transition into a SG at the end of the July meeting
We should then have discussion as if we were in a study group
We should start discussing PAR and CSD
The motion to create the study group is a formality that we need to do during the July meeting

5. Accelerated process for EHT
Assuming there is working group consensus to accelerate standards development timelines and target a rapid succession of 2/3 year cycle time for mainstream MAC/PHY projects, EHT should be the first candidate project for this approach

a proposed way forward, Osama Aboul-Magd
Looking at industry interoperability certification launches, we should have approximately 11ax wave 1 in 2019, 11ax wave 2 around EHT would naturally be 2023
EHT should define features for a single certification program and not 2, as was done for 11ac and 11ax, so its scope should be scaled accordingly
A new project would start 2 to 2 ½ years from now to define release.
In order to succeed with this approach, we need:
To be very strict in defining and respecting the timelines
To focus on the key features that show significant gains towards the objective of the project, and to list them
Potentially to provide visibility on the future projects, by providing a pre-list of features that would be considered for the project immediately following EHT

6. EHT timeline/roadmap July 2018: creation of EHT SG
Best option for start of EHT TG:
Jan 2019
Next possible start time of EHT TG:

8. EHT timeline/roadmap We believe we should start TG in January 2019
That gives us 2 to 2 ½ years to reach D1.0
2 years cycle: D1.0 needs to be ready for Q4 2020
2 ½ years cycle: D1.0 needs to be ready for Q2 2021
Starting in May 2019 is putting these cycles in jeopardy
Features that are agreed can be listed in the scope of the PAR
The 3 features listed today don’t require further studies and are providing sufficient gains to have insurance to meet an ambitious PAR
Features that are identified as interesting but require more studies can be listed as being under study/consideration
We can use the 4 months between September and January to discuss them, as well as during the initial TG phase
Example: Multi-AP time and frequency coordination
EHT should define features for a single certification program and not 2, contrary to what was done for 11ac and 11ax, so its scope should be scaled accordingly

9. Motion to create EHT Study group
Motion is a formality that we need to do in July.
Following the agreement we reached in May, we can easily define the motion text to create the study group by adapting the TIG motion into a SG motion
Next slide defines this baseline motion proposal
This is the baseline proposal that is agreed by all as an outcome of the May meeting
During the July meeting, we can further discuss and have presentations in order to see if we can have a scope that is even more precise and if we can have a motion text even more precise
If we need more time for this, we fall back naturally to the baseline motion proposal
The important document is anyway the PAR and CSD documents

10. Original proposed motion for EHT study group Based on TIG formation agreement
Approve the formation of the Extremely High Throughput (EHT) study group to consider development of a Project Authorization Request (PAR) and Criteria for Standards Development (CSD) for 1 to GHz operation
With the primary objective of increasing peak throughput to support high throughput applications such as video-over-WLAN, AR and VR.
Candidate features include but are not limited to: 320 MHz bandwidth, multiband aggregation and operation, and 16 spatial streams, as described in pptx.

11. Updated motion for EHT study group Based on discussion this week
Approve the formation of the Extremely High Throughput (EHT) study group to consider development of a Project Authorization Request (PAR) and Criteria for Standards Development (CSD) for 1 to GHz operation
With the primary objective of increasing peak throughput to support high throughput applications such as video-over-WLAN, AR and VR.
Candidate features include but are not limited to: 320 MHz bandwidth, multiband aggregation and operation, 16 spatial streams, as described in pptx and Multi-AP coordination
