Re: [STDS-802-11-TGBE] Group addressed BU delivery DCN 0503/r2



Hi Ming,

 

Thanks for your contribution, I have some comment on it.

How to understand the SP that “link specific”? Do you have the details solution that how AP schedule the GC BUs and TX to MLD and non-MLD STAs on different links, which not only guarantee MLD STAs to receive the non-duplicated GC BU, but also guarantee the non-MLD STAs to receive the whole GC BUs?

 

To make it simple and compatible with the legacy STA, I think it’s better to only allow GC BUs transmission on the primary link/configured link for MLD STA. If there is any non-MLD STA belong to the same group connected to MLD AP on other link, It’s allowed to duplicate the GC BUs on that link, and MLD STA should ignore these GC BU on it’s non-primary link/non configured link.

 

 

Thanks

 

Best Regards

 

Jay Yang

Hello all,

 

I proposed that Group addressed BU delivery is link specific and leave this transmission schedule to the AP in this contribution. Because of limited time for Q&A, please tell me if you have any comments.

 

I try to answer concerns for “switch”, I understand receiving group addressed BU has benefit to the non-AP side. Based on the balance between Rights and Obligations, it indeed requires non-AP to do something, such as switch. Moreover, it is not needed for single radio MLD to receive group addressed BU by switching frequently because it will park on one link for quite long time.  It is not like duplication, it does harm to legacy STA and single link STA and make every link congested.

 

  • Do you agree that group addressed BUs transmission immediately after DTIM beacon is link specific for an AP MLD
