Overview
• In r1, the following text was made into SFD:– LDPC is the only coding scheme in the HE PPDU Data field for allocation sizes of 996 tones
and 996*2 tones. – Support of BCC code is limited to less than or equal to four spatial streams (per user in case of
MU-MIMO), and is mandatory (for both TX and RX) for RU sizes less than or equal to 242 tones (20MHz).
– Support of LDPC code for both TX and RX is mandatory for HE STAs declaring support for at least one of HE 80/160/80+80 SU-PPDU bandwidths, or for HE STAs declaring support for more than 4 spatial streams. Otherwise, support of LDPC code for either TX or RX is optional.
– The 11ax MCS table shall not have any MCS exclusion and, when LDPC is applied, NDBPS is computed as follows
, where R is the coding rate
• The coding for 484-tone RU (40MHz) is still TBD.
• Here we propose 40MHz to be also LDPC-only.

Disallow BCC also in 40MHz
• Propose to also disallow BCC in 40MHz RUs, for the following reasons:– 80MHz devices would need doubled deinterleaver memory size compared
with 11ac, just to support 11ax 40MHz BCC (now with 468 tones).
– Easier parameters for padding symbol segment to avoid MCS exclusion.• Refer to [1]
– For padding, when a<4, LDPC leads to less processing delay than BCC, e.g. reduce PE duration.• Because BCC interleaver spreads the pre-FEC bits into all the tones.
– Low cost 2.4GHz-only devices most likely will implement 20MHz only, and dual-band device will support 80MHz in 5GHz anyways.

Slide 10 Hongyuan Zhang, Marvell, et. al.
• Do you make the following text changes in 11ax SFD (3.3.3 Coding)?– LDPC is the only coding scheme in the HE PPDU Data field for allocation sizes of 484 tones, 996 tones and 996*2 tones. – ….– Support of LDPC code for both TX and RX is mandatory for HE STAs declaring support for at least one of HE 40/80/160/80+80 SU-PPDU bandwidths, ……..
