Figs 15 and 18-19; see also Figs 5-14 and 16-17)].
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to integrate Shin’s method for network assisted interference cancellation with Balasubramanian’s method for active interference management and Byun’s method for performing device to device communications with the motivation being to improve performance (Balasubramanian, [0091]) and to perform device to device communication in share uplink resources (Byun, Title).
Regarding Claim 26, the claim discloses similar features as of Claim 1, and is rejected accordingly.
3a. Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Shin (US 20210067261 A1) in view of Balasubramanian (US 20200145963 A1) with Byun (US 20200178221 AI) and Deogun (US 20180199343 A1).
3b. Summary of the Cited Prior Art
Shin discloses a method for network assisted interference cancellation.
Balasubramanian’s discloses a method for active interference management.
Byun discloses a method for performing device to device communications.
Deogun discloses a method for supporting multiple numerology in wireless communication system.
Regarding Claim 12, Shin and Balasubramanian Do not disclose this claim.
However, Deogun discloses:
wherein the indication is received from a media access control-control element (MAC-CE)
[(see:
[0143] Referring to FIG. 3, this signaling should be at min-slot/symbol level. In an embodiment of the present disclosure, the active time period is indicated by the base station 100 using at least one of the explicit DCI signaling, an implicit DCI signaling, a MAC CE signaling, a time pattern, and a DRX signaling.
Figs 3-4)].
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to integrate Shin’s method for network assisted interference cancellation with Balasubramanian’s method for active interference management and Byun’s method for performing device to device communications and Deogun’s method for supporting multiple numerology in wireless communication system with the motivation being to improve performance (Balasubramanian, [0091]) and to perform device to device communication in share uplink resources (Byun, Title) and to improve the decoding of the PDCCH (Deogun, [0148]).
Conclusion
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
