DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on December 23, 2025 has been entered.
Response to Arguments
Applicant's arguments filed December 23, 2025 have been fully considered but they are not persuasive.
Applicants submit that Park describes a general precoder selection mechanism and an operational scenario where multiple TRPs use specific layer allocations during transmission. Park's generic distribution of layers for multi-layer transmission fails to teach or suggest that specific "set[s] of respective multiple columns" are "selected by the UE as sub-portions" of matrices that correspond to particular TRPs. Park further fails to teach or suggest that specific "sub-portions of' the respective matrices are reported "for each respective transmission reception point of the combination of transmission reception points associated with the transmission mode," and "for each transmission mode in a second subset of the plurality of transmission modes," as recited in amended independent claim 1.
In response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986).
Examiner submits that Gao teaches of wherein the respective partial precoding matrix information report for each transmission mode in the second subset (layer indicator, Paragraph 0292) indicates a set of multiple columns selected by the UE (from a layer indicator of a CSI report performed by the UE, Paragraphs 0040 and 0294) as sub-portions of a respective matrix (subset of columns, Paragraph 0294) for a respective transmission reception point of a combination of transmission reception points associated with the transmission mode in the second subset (TRP1/TRP2, TRP1/TRP3 and TRP2/TRP3, Paragraphs 0116 and 0251). Therefore, the combination of Gao, Park and Jin teach all the limitations of the independent claims.
Claim Rejections - 35 USC § 103
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 the 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:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. 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 1, 21, 24, 44 – 46 and 53 – 56 are rejected under 35 U.S.C. 103 as being unpatentable over Gao et al (US 2022/0094399) in view of Park et al (US 2020/0383091) and further in view of Jin et al (US 2019/0334594).

Jin teaches of a precoding matrix that is approximately represented by a weighted sum of a plurality of component matrices may need to be reconstructed before being used for precoding. A purpose of the reconstruction may be for setting precoding vectors of different receive end devices orthogonal to each other, so as to reduce interference caused by a signal sent to one receive end device to another receive end device. The reconstruction process may be performed according to a plurality of algorithms, for example without limitation to, a zero forcing (Zero Forcing, ZF) algorithm, a minimum mean square error (Minimum Mean Square Error, MMSE) algorithm, and a block diagonalization (Block Diagonalization, BD) algorithm (Paragraph 0169).
