Hi Nelson!
As I understand your comment, you believe the aSIFSTime definition shouldn't be included in the 802.11bp amendment.
If you refer to the base standard, you'll see that, with the exception of WUR PHY, the IEEE 802.11 standard includes the aSIFSTime value in every PHY definition. WUR PHY only defines DL PPDUs, so SIFS isn't required.
Below, you can see how the base standard defines aSIFSTime for each PHY in the 2.4 GHz band. (IEEE P802.11-REVmf/D2.0, February 2026)
In SP1 (DCN 11-26-0540-01-00bp), I propose following the base standard's approach in our amendment by including the definition of aSIFSTime.
PHY (2.4GHz) | aSIFSTime is in | aSIFSTime value (us) |
DSSS | Table 15-5—DSSS PHY characteristics | 10 |
HR/DSSS | Table 16-4—HR/DSSS PHY characteristics | 10 |
ERP | Table 18-5—ERP characteristics | 10 |
HT | Table 19-25—HT PHY characteristics | 10 |
HE | Table 27-61—HE PHY characteristics | 10 |
EHT | 36.4.4 EHT PHY refers to Table 27-61 (HE PHY Characteristics and Table 19-25 (HT PHY characteristics). | 10 |
