In Figure 16-9, which is the receive state machine, should the third step on the left ("SET RXPHY FIELDS") be "DETECT RXPHY FIELDS" or some such?

Change "SET RXPHY FIELDS" to "DETECT RXPHY FIELDS" or "VALIDATE RXPHY FIELDS".

REVISED (PHY: 2021-07-15 21:01:01Z)



Note to Commenter:

Following the convention in Figure 15-9, “SET RXPHY FIELDS” is changed to “RX PHY FIELDS”.



Instruction to Editor:

In Equation (21-13), the descriptions of Tsubfield for windowing function wTSubfield (t) is not correct for VHT-LTF and VHT-Data. It did not  take into account of the number of VHT-LTF symbols, and VHT-Data symbols in the transmission.

Tsubfield is ..., NVHT-LTFxTVHT-LTF for VHT-LTF and ...for VHT-SIG-B. Tsubfield is NSYMxTSYM for VHT-Data, that is ...

REJECTED (PHY: 2021-07-15 20:59:26Z)



REVme D0.0 P3150L31 says

“Each field … is defined as the summation of one or more subfields, where each subfield is defined to be an inverse discrete Fourier transform …”.

Hence, Equation (21-13) is describing a single OFDM symbol, and thus the windowing function is applied per OFDM symbol.  Therefore, the current text at REVme D0.0 P3151L28-36 is correct.

Scrambler currently has two modes of operation - one when CH_BANDWIDTH_IN_NON_HT is present and another when it is not present.  This sometimes causes confusion to readers on which mode to use in which situations.  Note that the functionality of the scrambler can be maintained w/o breaking any interop issues w/ existing devices even if we consolidate the scrambler mode to only one - the one used when CH_BANDWIDTH_IN_NON_HT is present.

Consolidate the scrambler operation mode to one.  More details on the text changes will be provided by the commenter during comment resolution.

REVISED (PHY: 2021-07-26 14:51:59Z)

Note to Commenter:

The proposed text update consolidates the scrambler operation into a single method.
