Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35
U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any
correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will
not be considered a new ground of rejection if the prior art relied upon, and the rationale
supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all
obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the
claimed invention is not identically disclosed as set forth in section 102, if the
differences between the claimed invention and the prior art are such that the
claimed invention as a whole would have been obvious before the effective filing
date of the claimed invention to a person having ordinary skill in the art to which
he claimed invention pertains. Patentability shall not be negated by the manner
in which the invention was made.
The factual inquiries for establishing a background for determining obviousness
under 35 U.S.C. 103 are summarized as follows:
• Determining the scope and contents of the prior art.
• Ascertaining the differences between the prior art and the claims at issue.
• Resolving the level of ordinary skill in the pertinent art.
• Considering objective evidence present in the application indicating
• obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the
claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any
evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to
point out the inventor and effective filing dates of each claim that was not commonly
owned as of the effective filing date of the later invention in order for the examiner to
consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2)
prior art against the later invention.
Claims 11, 16 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over CAO et al. in view of JANG et al. (US-20220209904-A1) hereinafter “JANG”.
Regarding Claim 11,
‘The apparatus of claim 10’ (disclosed above),
And didn’t discloses, ‘wherein the configuration of the first set of sequences comprises a sequence hopping pattern.’
JANG in the relevant art discloses, DCI transmitted by PDCCH identified by the UE uses scramble sequence includes DCI identifier and hopping [0104, 0107-0108].
Therefore, a person in the ordinary skill in the art before the effective filing date of
the claim invention would have recognized that the disclosure of CAO and to include
with that of JANG to come up with the claim invention,
CAO motive to perform MU-MIMO transmission uses allocation scheme for DMRS-configuration includes layer and sequence for MU-MIMO [0142, 0145, 0146-0147]. Includes scramble identifier [0100]. In Fig. 21, 22 and 33 illustrates MU-MIMO transmission includes GC-DCI and DMRS configuration that includes scrambling sequence [0246]. JANG includes signaling for group common DCI [0348] and PDCCH DCI includes, identifier DCI and hopping [0106] table 4 and table 5 [0107]. This would reduce delay and optimize system performance [0372].
Regarding Claim 16,
‘The apparatus of claim 1’ (disclosed above),
And didn’t disclose, ‘wherein to detect the at least one sequence, the one or more processors are configured to cause the apparatus to perform non-coherent detection to detect the at least one sequence.’
JANG in the relevant art discloses, NC-JT applied and received by the UE DCI for NC-JT configured based on multi-PDCCH. NC-JT supporting non-coherent precoding between cells, TRPs and/or beams. And, TCI indication to the channel characteristics for each link between each cell TRP and/or beam and the UE [0303]. The UE supporting NC-JT receiving configuration [0327]. A UE can use cooperative communication applied formats specific indicator are scrambled. Reception by the UE to which cooperative communication is applied condition NC-JT [0341].
Therefore, a person in the ordinary skill in the art before the effective filing date of
the claim invention would have recognized that the disclosure of CAO and to include
with that of JANG to come up with the claim invention,
CAO motive to reduce the delay of detecting PDCCH and optimize the system performance [0372]. Perform MU-MIMO transmission includes group common PDCCH uses DCI and UE-specific DCI in Fig. 22 and Fig. 33. Uses common search space [0280]. MU-MIMO transmission carried GC-PDCCH [0281]. JANG complements motive to perform NC-JT based on PDCCH [0327, 0341] and perform cell search and monitoring uses PDCCH [0118]. And, NC-JT to improve the throughput [0309].
Regarding Claim 18,
‘The apparatus of claim 1’ (disclosed above),
CAO discloses, ‘wherein the data comprises at least one of:
a hybrid automatic repeat request indication for uplink communications’ ( UE-specific PDCCH uses specific transmission control includes hybrid automatic repeat request [0293]);
And didn’t disclose,
‘a transmit power control indication for the uplink communications;
a timing advance command;
a preemption indication;
a wakeup signal;
a paging indication; or
a discontinuous reception indication.’ (JANG discloses DCI includes TPC scrambled UE-specific [0105]. And, table 5 and table 6 [0108-0109, 0122]. Motive would be identical disclosed in Claim 11 and Claim 16.)
