Office Action

§101 §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 . Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 6 and 17-21 are rejected under 35 U.S.C. 101 because giving its broadest and reasonable interpretation of a claim drawn to a computer storage medium typically covers form of non-transitory tangible media and transitory propagating signal per se. Regarding claim 6, the Examiner suggests changing to A non-transitory computer storage medium ... Claims 17-21 are rejected for the same reason as stated above. 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)(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. Claim(s) 1-3, 6, 8 and 17 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Davydov (US 20250286598). With respect to independent claims: Regarding claim(s) 1/2/6, Davydov teaches A method of operating a feedback radio node ([Fig.1A], UE 101) in a wireless communication network ([Fig.1A]), the method comprising; transmitting a measurement report ([0068], “reporting the calculated CSI from the UE to the gNB based on the CSI reporting configuration.”) based on measurement performed on DM-RS ([0068], “configuring the UE with CSI reporting using DM-RS of a PDCCH.”) associated to one or both received control signaling ([0068], “calculating of CSI reporting based on measurements of the DM-RS of the PDCCH.”) and data signaling. With respect to dependent claims: Regarding claim(s) 3/8/17, Davydov teaches transmitting the measurement report ([0068], “reporting the calculated CSI from the UE to the gNB based on the CSI reporting configuration.”) is one or both triggered by, and in response to, a control information message indicating the measurement report to be transmitted ([0068], “configuring the UE with CSI reporting using DM-RS of a PDCCH, requesting CSI reporting using a DCI transmitted in a PDCCH.”). 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. Claim(s) 5, 12, 14 and 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Davydov in view of Hao (US 20230247631). Regarding claim(s) 5/12/14/21, Hao teaches wherein the measurement report ([0146], UE may “generate a CSI report 550 for transmission.”) is based on measurement performed on DM-RS ([0147], “The DCI may schedule a downlink PDSCH with DMRS ... CSI may be measured or calculated based on DMRS.”) associated to a data transmission scheduled by a control information message ([0147], “The DCI may schedule a downlink PDSCH with DMRS.”) indicating the measurement report to be transmitted ([0146], “The base station may transmit an uplink related DCI 540 on one of the downlink slots 502 in the next frame for requesting an aperiodic CSI feedback.” And [0147], “The DCI may or may not indicate CSI reporting.” Further, [0106] “the base station may transmit a downlink grant that requests a CSI report.”) Therefore, it would have been obvious to one with ordinary skill in the art at the time before the effective filing date of the claim invention to have modified the method of Davydov to specify measuring DMRS of data signaling as taught by Hao. The motivation/suggestion would have been because there is a need to “use of the PDSCH/DMRS as the measurement resource may avoid using CSI-RS, thus reducing downlink signal overhead.” ([0107], Hao) Allowable Subject Matter Claims 4, 9-11, 13, 15-16, 18-20 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.
