Re: [STDS-802-11-TGBN] SP request for DSO

Hi Alfred,


Please queue the following SP on DSO to the TGbn MAC agenda.


Do you agree that:

  • only 80MHz UHR STAs and 160MHz UHR STAs can be DSO STAs

  • the DSO ICF-ICR exchange and the PPDUs that follows it shall only be between UHR STAs

  • one 80MHz subband in 320MHz BSS can be a DSO subband

    • whether more than one 80MHz subband can be a DSO subband in 320MHz BSS TBD

  • Secondary 80MHz in 160MHz BSS can be a DSO subband

  • Secondary 160MHz in 320MHz BSS can be a DSO subband


Supporting document: 11-24/1588r1


Regards,

Shubho

Hi Alfred,

Please queue the following two SPs on DSO topic to the TGbn MAC adhoc agenda.
  • Do you support that in the DSO ICF, the AP indicates to a DSO STA to switch to a DSO sub-band
    • Upon reception of the DSO ICF, the DSO STA shall
      • transition to the DSO sub-band,
      • transmit the response in the DSO sub-band a SIFS after the end of the DSO ICF
      • be ready to receive frames or be triggered to transmit frames, subject to its spatial stream capabilities and operation mode, in the DSO sub-band (derived from the DSO ICF), a SIFS after the end of the response frame
      • The baseline rules for CS required are followed.
  • Supporting document: 11-24/1553

  • Do you agree that if no non-AP STA that is assigned resources in the primary 20 MHz responds to the initial Control frame and there is at least one response on other channels, the AP shall do one of the following:
    • Terminate the frame exchange sequence with all non-AP STAs, or
    • Continue the frame exchange sequence by ensuring that the primary 20 MHz is occupied
  • Supporting document: 11-24/1553

Thanks,
Gaurang
