Proposal for Release 1/R2 Feature Split in Wireless AP Coordination
The proposal suggests modifying the split between Release 1 and Release 2 features for wireless AP coordination in order to address the lack of consensus on the low complexity AP coordination feature. It aims to enhance clarity and efficiency in the development process while maintaining the value of both releases. Key features for each release are outlined, emphasizing the need for a streamlined approach to ensure timely delivery and effective coordination among stakeholders.

May 2020 doc.: 20/0687r0 Meeting the timeline for D0.1 in September 2020 We are all committed to meet the timeline, and it starts with the first milestone (D0.1 in September 2020). To help achieving this, we have agreed in January a release framework, and defined a list of features for R1. Current release framework agreed in January 2020 Release 1 Features are: 320 MHz, 4KQAM, Multiple RUs per STA, Multi-link operation and a low complexity AP coordination feature Candidate Release 2 Features: 16 spatial streams, HARQ, Additional multi-AP features (e.g. C-BF, JT), any other potential features in the scope of PAR (e.g. features for Time-sensitive networks) Among the R1 features, the low complexity AP coordination feature was and is still very vague and undefined. Submission Slide 4 Laurent Cariou, Intel Corporation
May 2020 doc.: 20/0687r0 Multi-AP After 3 months of discussion, there is no consensus on what is the a low complexity AP coordination feature . Proponents of C-TDMA, proponents of C-SR, In the meantime, in spite of the large number of calls, the pace right now is slower compared to when we are able to meet face to face. We believe that it is safer timeline-wise to move this simple AP coordination topic to Release 2. We believe that it does not impact or reduce the value of Release 1, and that it would reinforce clarity of split between R1 and R2. Submission Slide 5 Laurent Cariou, Intel Corporation
May 2020 doc.: 20/0687r0 Proposal We propose to change R1/R2 split as follows: Release 1 Features are: 320 MHz, 4KQAM, Multiple RUs per STA, Multi-link operation and a low complexity AP coordination feature Candidate Release 2 Features: 16 spatial streams, HARQ, Additional multi-AP features (e.g. C-BF, JT, C-OFDMA/TDMA, C-SR), any other potential features in the scope of PAR (e.g. features for Time-sensitive networks) Submission Slide 6 Laurent Cariou, Intel Corporation
May 2020 doc.: 20/0687r0 Straw Poll Do you agree to remove a low complexity AP coordination feature from Release 1 features and to change 16 spatial streams, HARQ, Additional multi-AP features (e.g. C-BF, JT), any other potential features in the scope of PAR (e.g. features for Time-sensitive networks) to 16 spatial streams, HARQ, multi-AP features (e.g. C-BF, JT, C-OFDMA/TDMA, C-SR), any other potential features in the scope of PAR (e.g. features for Time- sensitive networks) to candidate Release 2 features Submission Slide 7 Laurent Cariou, Intel Corporation
