Hi Gaurang,
Thanks for the clarification.
BTW, could you help define some rules of Link ID based on the cited motion as your guy Abhi is the POC on this?
E.g. how to number each link of MLD with Link ID, the initial value of Link ID. etc.
As you know, the Link ID =15 is already used in Laurant’s PDT, but we don’t know what’s the Link ID=15 meaning.
Thanks
Best Regards
Jay Yang

Hello Jay,
Thank you very much for reviewing the CR document.
Regarding your question, if there a channel switch on a link, the Link ID *will not* change. Pls refer to the text below from 35.3.4.4 of D0.4 (page 197, line 8):
An AP of an AP MLD shall have a unique link ID that shall not change during the lifetime of the AP MLD.
Let us assume that an AP MLD has three links. The mapping will be something link this:
Link ID Tuple
0 <Cl_1, Ch_1, BSSID_1>
1 <Cl_2, Ch_2, BSSID_2>
2 <Cl_3, Ch_3, BSSID_3>
Now, let us say the channel on link 0 changes from <Cl_1, Ch_1> to <Cl_4, Ch_4>, the new mapping will be:
Link ID Tuple
0 <Cl_4, Ch_4, BSSID_1>
1 <Cl_2, Ch_2, BSSID_2>
2 <Cl_3, Ch_3, BSSID_3>
So, the Link ID will not change. Only the tuple value will change. Link ID 0 will now map to the tuple <Cl_4, Ch_4, BSSID_1>.
The relationship between the Link ID and the <class, channel, BSSID> tuple was specified in Motion 124, SP 186. Pls see the text below. The note simply captures the motion.
Please let me know if that answers your question.
Thanks,
Gaurang

Hi Gaurang,
Thanks for the PDT.
For following sentence, as you mentioned, The Link ID is unique value to identify every AP within the AP MLD. But if the AP switches the working channel, it means the Operating class and channel are also changed accordingly. Seems it’s
not correct to tie the Link ID to the tuple<class, channel, BSSID>. Or do you mean the Link ID also can be changed?
[CID 3127]NOTE ? The Link ID of an AP affiliated with an AP MLD is a representation
of the tuple consisting of Operating Class, Operating Channel, and BSSID of the AP affiliated with the AP MLD. The Link ID is unique to every AP affiliated with an AP MLD.
Thanks
Best Regards
