[STDS-802-11-TGBN] PHY Motions request for May 2025

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:

              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:

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

Add the following paragraph in 802.11bn 3.1 Definitions subclause:

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
