The indication of the feedback BW goes in NDPA. • – The granularity of channel feedback requested by the AP is a 26 tone RU. The AP signals start and end 26 tone RUs requested for feedback. • – NOTE—The tone grouping factor, Ng is defined with respect to data tones of the HE PPDU. [PHY Motion 101, January 2016, see [139]] AP shall control the Ng, quantization, and Nc of the sounding FB in NDPA except in the special case of a NDPA addressed to a single STA which requests SU type feedback. In the aforementioned special case, the STA controls these quantities. • • NOTE—The tone grouping factor, Ng is defined with respect to data tones of the HE PPDU. [PHY Motion 38, September 17, 2015, see [138]] 802.11ax spec shall support Ng = 4 and 16 for sounding feedback with SU/MU-MIMOOFDM(A). • • – [PHY Motion 149, March 2016, see 16/389] 802.11ax spec shall not support Ng = 1 for sounding feedback. • • – [PHY Motion 148, March 2016, see 16/389] [PHY Motion 151, March 2016, see 16/389] This proposal addresses the HE NDPA frame format Submission Slide 12 Ross Jian Yu, Huawei et al May, 2016 doc.: IEEE 802.11-16/0609r1 VHT NDPA frame format Recap • VHT NDPA includes AID12, SU/MU feedback type and number of columns Bytes: 2 6 6 1 2 2 Duration RA TA Sounding Token STA Info 1 STA Info 2 2 Frame Control 2 6 B11 B0 Bits: Submission 4 STA Info n FCS Sounding Token Number Reserved Bits: …. 2 B12 AID12 Feedback Type 12 1 B13 B15 B0 Nc 3 Slide 13 Bits: B11 B12 AID12 Feedback Type 12 1 B13 B15 Nc 3 Ross Jian Yu, Huawei et al May, 2016 doc.: IEEE 802.11-16/0609r1 HE NDPA frame format • In HE NDPA we need 4 Byte for per STA Info: – – – – AID per STA = 11bit Feedback type per STA: SU/MU/CQI per-STA = 2bits Ng per-STA = 1bit (Ng = {4,16}) Codebook size per-STA = 1bit (quantization resolution = {(2,4),(4,6)} when feedback type = SU, quantization resolution = {(5,7),(7,9)} when feedback type = MU) – Nc per-STA = 3bits (Nc = 1…8) – Partial BW Info per-STA of feedback report = 14 bits • We suggest to reuse the frame type/subtype of VHT NDPA – HE NDPA and VHT NDPA serve similar function – Only 3 reserved subtype for control type, need to reserve subtype values for future use Submission Slide 14 Ross Jian Yu, Huawei et al May, 2016 doc.: IEEE 802.11-16/0609r1 HE NDPA frame format • The proposed HE NDPA frame format reusing the type/subtype of VHT NDPA is shown as below: – Only for HE NDPA aimed at more than one STAs … Frame Control Duration RA Octets: 2 2 6 TA Sounding Dialog Token STA Info 1 STA Info n FCS 6 1 4 4 4 B0 B0 Bits B1 B2 B10 B11 Reserve d VHT/HE 1 1 6 B27 B28 B29 B31 Partial BW Info Feedback type + Ng Disam biguati on bit Codebook size Nc 11 14 2 1 1 3 Bits: Submission B26 AID11 B7 Sounding Dialog Token Number B24 B25 Slide 15 Start RU End RU 7 7 Ross Jian Yu, Huawei et al May, 2016 doc.: IEEE 802.11-16/0609r1 Changes Compared with VHT NDPA • • VHT/HE (B1 of sounding dialog token) : to help all HE STAs to differentiate between VHT NDPA and HE NDPA. Per STA Info extends from 2 Byte to 4 Byte to include more info: – AID11: 11 LSB of the AID of an HE STA expected to process the following HE NDP and prepare the sounding feedback. – Partial BW Info: signals the start index and the end index 26 tone RUs requested for feedback (7 bit is needed for maximum 74 RUs for start/end RUs). – Disambiguation bit (B27): set to 1 to prevent VHT STA from parsing B16-B27 as his own AID – Feedback + Ng + codebook size (2+1 bits) jointly indicate: Feedback type + Ng + codebook size Submission Description 000 SU, Ng4, quantization resolution = {2,4} 001 SU, Ng4, quantization resolution = {4,6} 010 SU, Ng16, quantization resolution = {2,4} 011 SU, Ng16 quantization resolution = {4,6} 100 MU+Ng4, quantization resolution = {5,7} 101 MU+Ng4, quantization resolution = {7,9} 110 CQI only feedback 111 MU+Ng16, quantization resolution = {7,9} Slide 16 Ross Jian Yu, Huawei et al May, 2016 doc.: IEEE 802.11-16/0609r1 Further Explanation Regarding VHT STAs Behavior • Some further explanations regarding VHT STAs behavior: – AID11 in STA info 1 of HE NDPA is the AID of an HE STA, hence VHT STA will not parse B0-B11 as its own AID. – Disambiguation bit corresponds to the MSB of AID12 of the 2nd STA in VHT NDPA, and is set to 1, making AID12 > 2048 , never match the AID of a VHT STA.

Submission Slide 18 Ross Jian Yu, Huawei et al May, 2016 doc.: IEEE 802.11-16/0609r1 Straw Poll • Do you agree to add to the SFD the HE NDPA frame format as shown in slide 15 and 16 of 0609r1? – Y – N – A Submission Slide 19 Ross Jian Yu, Huawei et al
