Office Action

§102 §103
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 . DETAILED ACTION Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1 and 12 are rejected under 35 USC 102(a)(1) and 35 USC 102(a)(2) as being anticipated by Faxer et al (US 2022/0052734, “Faxer”). Re claims 1 and 12, Faxer discloses an apparatus, comprising: a transceiver (figure 5, element 511) which, during operation, wirelessly communicates with at least one network node of a network side (figure 5, element 560); and a processor (figure 5, element 520) communicatively coupled to the transceiver such that, during operation, the processor performs operations comprising: receiving, via the transceiver, a reference signal transmitted by the network side (paragraph [0007]); deriving a channel response information observed by a receiving domain of the apparatus according to the reference signal (paragraph [0007]); decomposing the channel response information into a two-dimensional domain to obtain a linear combination coefficient representation of the channel response information in the two- dimensional domain ((paragraph [0073]); and reporting, via the transceiver, a compressed channel information to the network side based on the linear combination coefficient representation and the two-dimensional domain (paragraph [0073]). Re claims 2 and 13, Faxer discloses the two-dimensional domain comprises a first domain related to a network side spatial domain transformation and a second domain related to a frequency domain transformation (paragraph [0073]). Re claims 3 and 14, Faxer discloses the transformation of the first domain and the second domain is based on Fourier transform (paragraphs [0005] and [0024]). 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 of this title, 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. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Faxer in view of Lee et al (US, “Lee”). Re claims 1, 11 and 21, Faxer discloses all of the limitations of the base claim, but fails to disclose Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Faxer with Lee for the benefit of providing. Allowable Subject Matter Claims 4-6 and 15-17 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
