Hi Ming and all, This is to have follow up discussions on yesterday’s presentation regarding 20/0427 Synchronous multi-link operation. First of all, thank you very much for your valuable comments during the call. To the best I remember, the concern that Ming has is that the duration of immediate response frame can be long such that continuing a TXOP when the AP MLD does not receive the immediate response frame correctly may not be appropriate.
If the duration of the immediate response frame becomes longer, it is true that the chance of the wireless medium (that BA was not sent) becomes busy will increase. And, also I agree with you that it is not appropriate to continue the AP
MLD’s TXOP if the channel becomes busy. However, this is why I propose to have CCA before resuming the TXOP in the SP. Therefore, the AP MLD will continue the TXOP on the link that BA is not successfully received only if the channel remains idle before resuming the TXOP. I think this procedure is actually in line with current PIFS recovery rule (The only difference is that the CCA measurement duration is extended from PIFS to whole BA + SIFS duration). Please let me know if I misunderstood your comment.
