Re: [STDS-802-11-TGBN] Motion Request MAC - Roaming

Hi Alfred,

 

Could you please add the following to the Motions for MAC?

Move to add the following to the 11bn SFD

•TBD request frame initiating roaming preparation carries the DH parameter element of the non-AP MLD when new PTK is derived
•TBD response frame during roaming preparation carries DH parameter element generated by the target AP MLD when new PTK is derived
•Non-AP MLD and the target AP MLD derive the PTK based on the shared PMK and DHss in TBD request and TBD response frames? 
Supporting list: [24/1882, 24/1883]

          Result: No objection 


Regards, 

Chitto

Dear Alfred,

Move to add the following to the 11bn SFD

  • Do you support allowing a second mode for security in roaming (in addition to the first mode with single TK used across all AP MLDs of the SMD) where a non-AP MLD can derive a new TK under the same PTKSA with the target AP MLD?
    • The new TK is derived as part of the single PTKSA
    • The PN is maintained per PTKSA: The new TK negotiated with the target AP MLD shares the same PN space with the TK of the current AP MLD (PN is monotonically increasing)

Supporting list: [24/1882, 24/1883, 24/1884, 24/1874]

Result: No objection

 

 

Move to add the following to the 11bn SFD

  • During the TBD time for retrieving DL from the Current AP MLD, the non-AP MLD may provide an indication to the Target AP MLD that the TBD time for DL retrieval is early-terminated before the TBD time?
  • TBD signaling of the indication

Supporting list: [24/1882, 24/1883, 24/1884, 24/1898, 24/1874]

Result: No objection

 

To all, please let me know if you wish to add your DCNs as supporting documents.

 

Thanks,

Giovanni
