Hi all, This email is for the discussion of eMLMR switching to multiple link CCA. If you have comments, please let me know. ((#5223, 5224, 6067) Within a TXOP initiated by an AP affiliated with AP MLD, the non-AP MLD
shall switch back to do the CCA operation on the EMLMR links after the time indicated in the EMLMR Transition Delay subfield of the EML Capabilities subfield in the Common Info field of the Basic Multi-Link element if any of the following conditions is met
and this is defined as the end of the frame exchanges:
—
The MAC of the STA affiliated with the non-AP MLD that received the initial frame
does not
receive a
PHY-RXSTART.indication primitive
during a timeout
interval of
aSIFSTime
+ aSlotTime
+ aRxPHYStartDelay
starting at
the end
of the
PPDU transmitted
by the
STA of
the non-AP MLD as a response to the most recently received frame from the AP affiliated with the
AP MLD
or starting
at the
end of
the reception
of the
PPDU containing
a frame
for the
STA from
the AP
affiliated with
the AP
MLD that does
not require
immediate acknowledgement.

requires immediate response
