Hi all,
This is Myeongjin (MJ) Kim from Samsung.
A few weeks ago, I sent the mail below to get feedback to resolve CIDs of 1249, 1250, 1962, and 3275 which were deferred during the call.
But, I did not get any feedback..:)
If I do not receive any feedback by this weekend, I will request to have a presentation to resolve CIDs of 1249, 1250, 1962, and 3275 as below.
So, please let me know if you have comments or suggestions.
Thank you.
Best regards,
MJ

Title : Discussion on CIDs of 1249, 1250, 1962, 3275
Hi all,
This is Myeongjin (MJ) Kim from Samsung.
During the last PHY call, CIDs of 1249, 1250, 1962, 3275 in 11/21-0417r2 were deferred since there were different opinions on these comments.
Especially, there was a discussion on mandatory support for small size MRU and large size MRU in OFDMA transmissions. But, we didn't get the conclusion.
So, I would like to have offline discussion here to resolve the these CIDs.
The followings are initial resolutions based on the passed motions in SFD.
CID | Page. Line | Clause Number | Comment | Proposed Change | Resolution |
1249 | 194.30 | 36.3.2.3.3 | "It is mandatory for non-AP STA to support the transmission and reception"'. Should also clarify the mandatory requirement for AP | as in comment | Rejected.
Based on the passed motion (Motion 115, #SP72) in SFD, large size MRU combinations in OFDMA are mandatory for non-AP STA only.
|
1250 | 194.34 | 36.3.2.3.3 | "unless the MRU size is larger than its supported bandwidth" should be changed "unless MRU is outside of the STA support BW" since a 484+242 MRU in seconday 80MHz has size less than an 80MHz STA's supportiing BW but can not be supported by this STA | as in comment | Rejected.
36.3.2.2 (Support of wide bandwidth OFDM operation) specifies that RU/MRU which are not fully within the STA’s operating location do not need to be supported.
|
1962 | 187.45 | 36.3.2.3.2 | "It is mandatory for a non-AP STA to support the transmission and reception of 26+52 tone and 26+106 tone MRUs in OFDMA." What about AP? The support of small-size MRUs should be mandatory at the AP too. | Add the mandaory support of small size MRUs for AP. At least add the mandatory receive of small size MRU at the AP. | Rejected.
Base on the passed motion (Motion 115, #SP71) in SFD, small size MRU combinations in OFDMA are mandatory for non-AP STA only.
|
3275 | 194.33 | 36.3.2.3.3 | In "2×996+484 tone MRU, 3×996-tone MRU, and 3×996+484 tone MRU in 80/160/320 MHz PPDU in OFDMA", it should be 320 MHz PPDU in OFDMA. | delete 80/160/ from the sentence. | Revised.
Agree with the commenter. But, for the better description, “for an OFDMA EHT PPDU” is changed to “for an OFDMA 80/160/320 MHz EHT PPDU” in this sentence.
Instructions to the editor: Please make the changes as shown in 11/21-0000r0 |
Instructions to the editor
Please make the changes to P194 L33 as shown below: (The baseline for this text is 11-21/0417r3.)
It is mandatory for a non-AP STA to support the
transmission and reception of 484+242-tone MRU in each 80 MHz frequency
subblock, 996+484-tone MRU in the primary 160 MHz channel and the secondary 160
MHz channel, 2×996+484-tone MRU, 3×996-tone MRU, and 3×996+484-tone MRU in 80/160/320
MHz channel for an OFDMA 80/160/320 MHz EHT PPDU unless the MRU size is larger
than its supported bandwidth.
Please feel free to discuss in this email thread.
Thank you.
Best regards,
MJ
