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

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:

              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
