Re: [STDS-802-11-TGBE] draft text for "PDT-Resource unit-Interleaving for RUs and aggregated RUs"

Hi Jianhan,

I reviewed this 1447r1. I have following 4 comments:
(1) This is in page 2. In description of small-size MRUs, "The 26+52 tone MRU is obtained by combining a 26-tone RU and a 52-tone RU that both fall within a 20MHz channel boundary." is not strict. Prefer to say that they are adjacent 26-tone RU and 52-tone RU. Same comment for definition of the 26+106 tone MRU.
(2) In the small-size MRUs subclause, shall we use MRU indices for these small-size MRUs? We have RU indices for all RUs in the OFDMA tone plan. We also have MRU indices for large-size MRUs.
(3) Need to highlight 3 additional places related to non-contiguous BW modes (e.g., 80+80, 160+160) as TBD. In page 6, last sentence before Figure 34-X9, and 2nd line in the paragraph after Figure 34-9X; in page 9, 2nd line in the paragraph after Figure 34-X14.
(4) In the large MRUs subclause, is there a reason why we define the MRUs for non-OFDMA, followed by the MRUs for OFDMA? Majority of MRUs are in both non-OFDMA and OFDMA. This results in a lot of redundancy.

Hi Jianhan,

 

Thanks for drafting this section. I have some comments:

 

  1. On P2, you marked pilot subcarriers for RU26+52 and RU26+106 as TBD. Actually there is a passed motion 115 addressing this

 

802.11be supports that pilot subcarriers for small/large RU combinations includes the pilot subcarriers of each RU.

[Motion 115, #SP80, [10] and [74]]

 

  1. In the text, for those 80+80 and 160+160,  they may need to be highlighted in yellow to be consistent with other PDTs
  2. 11be should be referring to Section 34.xxx or something, but should not be 27.xxx

 

Thanks,

Lin
