Hi Alfred,

Please also help to add the following SPs to the PHY Motion list:

Motion 1: Do you agree to add the following table at the end of the subclause 38.3.23.4.3: Transmitter constellation error of next revision of 11bn draft? (DCN #721/r3, #726/r0)

Table 38-xx —Allowed relative constellation error versus constellation size and coding rate for ELR

Modulation

Coding rate

Relative constellation error in a UHR

ELR PPDU (dB)

BPSK

1/2

-4

QPSK

1/2

-5

Result: no objection

Motion 2: Do you agree to include the following to the 11bn SFD? (DCN #721/r3)

The PSDU length for receiver minimum input sensitivity and adjacent channel rejection measurement shall be 512 octets for UHR ELR PPDU.

Result: no objection

Motion 3: Do you agree to include the following to the 11bn SFD? (DCN #721/r3, #726/r0)

Receiver Minimum Input sensitivity for new MCSs are as follows:

Result: no objection

Motion 4: Do you agree to include the following to the 11bn SFD? (DCN #721/r3, #726/r0)

Minimum required adjacent and nonadjacent channel rejection levels for four new MCSs are as follows

Result: no objection

Thanks,

Thanks Ross for the offline comment.

Hi Alfred,

Following Ross’s comments, direct spec changes related SP does not need to go to SFD.

Please use the following version, sorry for the inconvenience.

Motion 1: Move to remove the “TBD” in the “spatial reuse” subfield in UHR-SIG of UHR MU PPDU, U-SIG of UHR TB PPDU, Common Info and Special User Info Field of the trigger frame in the next revision of 11bn draft(DCN# 11-25/687r1).

Note: Remove the “TBD” means SR subfield will be kept the same as that in EHT.

Result: no objection

Motion 2: Move to add the following paragraph in OBSS PD-based Spatial reuse operation subclause of the next revision of 11bn draft(DCN# 11-25/687r1):

A UHR STA follows the rules defined in 35.10.2 (OBSS PD-based spatial reuse operation), except that the condition 5 defined in 26.10.2.2 (General operation with non-SRG OBSS PD level) is updated as follows:

The received PPDU is one of the following:

For non-EHT PPDU, the SPATIAL_REUSE subfield (if present) is not set to PSR_AND_NON_SRG_OBSS_PD_PROHIBITED.
For other PPDUs, the SPATIAL_REUSE subfield is present and is not set to PSR_AND_NON_SRG_OBSS_PD_PROHIBITED.

NOTE— As a result, a UHR STA is not allowed to use OBSS PD-based spatial reuse when the received PPDU is a UHR ELR PPDU or a value of PHY Version Identifier field in U-SIG is one of Validate values.

Result: no objection

Motion 3: Move to add the following paragraph in 3.1 Definitions subclause of the next revision of 11bn draft(DCN# 11-25/687r1):

non-extremely-high-throughput (non-EHT) physical layer (PHY) protocol data unit (PPDU): [non-EHT PPDU] A PPDU that is transmitted using a PPDU format defined in Clause 15 (DSSS PHY specification for the 2.4 GHz band designated for ISM applications), Clause 16 (High rate direct sequence spread spectrum (HR/DSSS) PHY specification), Clause 17 (Orthogonal frequency division multiplexing (OFDM) PHY specification), Clause 18 (Extended Rate PHY (ERP) specification), Clause 19 (High Throughput (HT) PHY specification(#2297)), Clause 21 (Very high throughput (VHT) PHY specification) or Clause 27 (High Efficiency (HE) PHY specification).

Result: no objection

Motion 4: Move to include the following text to the 11bn SFD (DCN# 11-25/389r2, 11-25/687r1 and 11-25/842r0):

UHR STA shall set the Spatial Reuse subfield to ‘PSR_AND_NON_SRG_OBSS_PD_PROHIBITED’ in the Co-SR and Co-BF transmission.

Result: no objection

Thanks,

Juan

Hi Juan,

For Motion 2, do you intend for SFD or spec? If for spec, could you be more specific on the instruction to editors?

Hi Alfred,

Please help to add the following passed SPs to the PHY Motion list:

Motion 1: Move to include the following text to the 11bn SFD (DCN# 11-25/687r1):

Remove the “TBD” in the current “spatial reuse” subfield in UHR-SIG of UHR MU PPDU, U-SIG of UHR TB PPDU, Common Info and Special User Info Field of the trigger frame.

Note: Remove the “TBD” means SR subfield will be kept the same as that in EHT.

Result: no objection

Motion 2: Move to include the following text to the 11bn SFD (DCN# 11-25/687r1):

Add the following paragraph in 11bn OBSS PD-based Spatial reuse operation subclause:
