Response to Remarks/Arguments
Applicant’s argument:
Applicant argued that the references cited do not disclose " terminating the second TXOP and continuing to transmit during the first TXOP in response to the detecting the transmission failure on the first wireless link ", as cited in claim 1.
Examiner’s response:
Applicant’s argument with respect to the pending claims have been fully considered, but they are not persuasive for at least the following reasons:
The primary reference KWON discloses the inventive concept of the limitation in paragraph [0053] the first frame is transmitted on link1 , the link1 fails , the TXOP period is still ongoing(i.e., continue), the first frame has priority higher than second frame , the first frame is transmitted on link2
Thus, KWON discloses explicitly that the transmission on the secondary link is stopped (i.e., terminated) to allow the transmission of the first frame in the second link base the priority of the first frame, where the TXOP period is still ongoing(i.e., continue).
However, KWON does not explicitly the word “terminating” for example , “terminating the second TXOP …in response to the detecting the transmission failure on the first wireless link
in the same filed, HWANG discloses the limitation “terminating the second TXOP …in response to the detecting the transmission failure on the first wireless link in [0103] discloses the access point may acquire a transmit opportunity (TXOP) , wherein the access point transmits frames in a first link and a second link , wherein a reception error for a data frame (e.g., PPDU) may occur in the first link (i.e., failure), where [0110] – [0112] the access point terminates the TXOP by transmitting a contention free (CF)-END frame in each of the first link and the second link
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify KWON by terminating the second TXOP …in response to the detecting the transmission failure on the first wireless link, as taught by HWANG, in order to terminate the TXOP on the link (see HWANG [0110] – [0112]).
Based on the fact, Examiner respectfully disagrees that the prior art cited does not teach the limitation of the independent claim 1, as argued by applicants. The other Independent Claims, recite features analogous to those of Claim 1, the cited passages teach the other independent claims, as well. Furthermore, the cited passages teach dependent claims, as well.
