Technical Editor	Robert Stacy (Intel)

Background

In May 2013, the High Efficiency WLAN Study Group (HEW SG), a study group within IEEE 802.11 working group had started its activity to consider the improvement of spectrum efficiency to enhance the system throughput/area in high density scenarios of APs and/or STAs.

The study group was created based on the following straw poll and motion:

< Straw Poll >
Do you support starting a new study group called “high efficiency WLAN” to enhance 802.11 PHY and MAC in 2.4 and 5GHz with a focus on:

Improving spectrum efficiency and area throughput
Improving real world performance in indoor and outdoor deployments

in the presence of interfering sources, dense heterogeneous networks
in moderate to heavy user loaded APs

< Motion >
Request an approval by IEEE 802 LMSC to form an 802.11 Study Group to consider High-efficiency WLAN [as described in doc 11-13-0339r2] with the intent of creating a PAR and five criteria.

The HEW SG has successfully developed PAR and CSD documents and the project 802.11ax has started in May 2014.

Spatial Reuse issues were discussed at length.

Slow progress on SRP-based SR.

Proposal to include simplified simulation models in the TG simulation scenarios document was discussed and passed straw poll.
Agreed to hold an ad hoc meeting in San Diego, from March 8th to 10th, 2017.
Vacant positions of ad hoc co-chairs are filled.

Achievements

Work Completed

TGax received about 70 submissions.

Numbers of submissions: PHY/MAC/MUSR/TG = 33/18/9/3/6.

Agreed to terminate the Specification Framework process. The frame of reference is Draft D0.1.

Future submissions shall bring text to continue developing the TG draft.
The TG Technical Editor is planning to generate draft D0.2 based on outcome of this meeting.

Approved the resolutions of about 200 comments, most of them addressing the PHY clause.
