Dear all, Thanks for your review and valuable feedbacks. I have uploaded the revised version to mentor, please let me know if there are further comments. Regards, Rojan From: Rojan Chitrakar <rojan.chitrakar@xxxxxxxxxxxxxxxx>
Hi Yongho, You are right, I made a mistake. The note should have been as below: NOTE – In order to prevent the receiver from discarding a newer frame as a replayed frame due to an older retransmitted frame, the PN used to protect the frame is not incremented when the frame is retransmitted. Consider the following simple scenario:
I agree with you that this requirement is similar to the one in baseline, however it is not apparent that the baseline rule covers the case of retransmission on a different link since the A1/A2 may be different. Alternatively, I can add
a simpler note based on the baseline text: NOTE—Retransmitted MPDUs are not encapsulated with a new PN when retransmitted on another link. What do you think? Regards, Rojan From: Yongho Seok <yongho.seok@xxxxxxxxx>
Hi Rojan, Regarding "NOTE 2 – In order to prevent the receiver from discarding a retransmitted frame as a replayed frame, the PN used to protect the frame is not incremented when the frame is retransmitted. (#2598)" Isn't this conflicted with the following baseline rule? If you increase the PN of the retransmitted frame, why is it discarded? The PN is greater than the value of the replay counter. I understand the PN of the retransmitted MPDU should not be changed. The baseline also has the following text.
(#4613)NOTE—Retransmitted MPDUs are not modified on retransmission. But, I am not sure whether "To prevent something" is correct in your NOTE 2. Thanks, Yongho 2021년 3월 15일 (월)
