Hi Ron, About:
I assume only one punctured subband will be signaled in the beacon and will be limited to the non-ofdma puncturing patterns we defined in the spec (other cases STA doesn’t implement).
I see 455r2 uses a 16-bit bitmap to indicate the (static) puncturing pattern. I don’t believe anyone really expects to use the full flexibility of this 16 bit indication, but
we should probably be more explicit about the restrictions you mention when it comes to static puncturing. Regards, Sigurd From: Ron Porat <000009a0da80e877-dmarc-request@xxxxxxxxxxxxxxxxx>
This email was sent from outside of MaxLinear. Hi Wook bong, That rule is an unnecessary constraint/requirement. My thinking based on the discussion is that we need a two-fold solution which seems natural based on 11ax
design and puncturing mask we adopted in 11be:
I assume only one punctured subband will be signaled in the beacon and will be limited to the non-ofdma puncturing patterns we defined in the spec (other cases STA doesn’t implement).
Thanks, Ron From: Wook Bong Lee <wookbong.lee@xxxxxxxxxxx>
Hi Jianhan, That is only if we don’t allow non-AP STA to transmit higher than MCS 7 power level. If that is what members wants, then we need to make a rule like
E.g. when allocates non-contiguous MRU, AP STA shall assume an non-AP STA uses transmit power less than the maximum power of EHT-MCS 7. Best regards, Wook Bong Lee From: Jianhan Liu [mailto:Jianhan.Liu@xxxxxxxxxxxx]
-29 to -38 dB is always more tighter than -20 to -25dBr (puncture mask), right?
Then puncture mask becomes less useful then if puncture cases cannot be always identified.
Thanks, Jianhan From: Wook Bong Lee [mailto:wookbong.lee@xxxxxxxxxxx]
Hi Jianhan and Ron, Punctured mask: -20 to -25dBr Max(EVM – 2,-38): -15 to -38 dB depending on modulation level If we only allow power level less than or equal to the maximum power of EHT-MCS 7, then
Max(EVM – 2,-38): -29 to -38 dB. Best regards, Wook Bong Lee From: Jianhan Liu [mailto:Jianhan.Liu@xxxxxxxxxxxx]
Hi All, For epsilon-2 in option 3, in which cases that the unused tone mask is tighter than punctured mask? Thanks, Jianhan From: Ron Porat [mailto:000009a0da80e877-dmarc-request@xxxxxxxxxxxxxxxxx]
Hi Wook bong, Xiaogang, For the regular unused tone mask we could go with epsilon-2 in option 3 to make it tighter and that should be sufficient to expand the 11ax style requirement
to non-contiguous MRU. If on top of that we want to add some new requirement based on section 36.3.19.1.2 we need to be a bit more careful and discuss it separately. Since the STA
is not in control (unlike SU) and doesn’t know if and where there is a disallowed subchannel we may want to limit it to only a subchannel conveyed in the beacon (static puncturing) and further decouple the requirement from the M-RU size (e.g. case 3 therein). Thanks, Ron From: Chen, Xiaogang C <xiaogang.c.chen@xxxxxxxxx>
Thanks Wook Bong to initiate this. One thing to consider is regulatory may not differentiate puncture and unallocated. They only differentiate adjacent and non-adjacent subchannel. Given that, regarding the unused EVM of the frequency portion of the “hole”, fully rely on
e or
e-2 may violate the regulatory requirement (for low MCS) if the interpretation of the unused “hole” is just “non-adjacent”.
So IMO puncture mask is safer for the “hole”. BRs, Xiaogang. From: Wook Bong Lee <wookbong.lee@xxxxxxxxxxx>
