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 .
Claim Rejections - 35 USC § 102
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 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.
Claims 1, 2, 4, 5, 7, 9-11, 14-16, 18, and 21-24 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Haustein et al. (US 2025/0039044 A1, “Haustein”).

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 the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 3, 12, and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Haustein in view of Cirkic et al. (US 2019/0140726 A1, “Cirkic”).
Regarding claim 3:
Haustein is silent regarding signaling, to the network node, recommended CSI feedback generation configuration parameters for the network node to update the second set of CSI feedback generation configuration parameters.
Cirkic teaches UE signaling to a network node recommended CSI feedback configuration parameters for the network node to update CSI feedback configuration parameters (e.g. [0051], [0053], Fig. 4, 403 and 404).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the system of Haustein based on the teaching from Cirkic to include the feature signaling, to the network node, recommended CSI feedback generation configuration parameters for the network node to update the second set of CSI feedback generation configuration parameters, in order to optimize CSI reporting and overall network performance.
Regarding claim 12:
Haustein is silent regarding the channel information is based on uplink channel measurements, or a CSI report received from the WD.
Cirkic teaches determining updated CSI configuration based on uplink channel measurements, or a CSI report received from the WD (e.g., [0051], [0053], Fig. 4, 403 and 404).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the system of Haustein based on the teaching from Cirkic to include the feature the channel information is based on uplink channel measurements, or a CSI report received from the WD, in order to optimize CSI reporting and overall network performance.
Regarding claim 13:
Haustein is silent regarding receiving, from the WD, recommended CSI feedback generation configuration parameters; and determining the updated set of CSI feedback generation configuration parameters based at least in part on the recommended CSI feedback generation configuration parameters.
Cirkic teaches receiving, from the WD, recommended CSI feedback generation configuration parameters; and determining updated set of CSI feedback generation configuration parameters based at least in part on the recommended CSI feedback generation configuration parameters (e.g., [0051], [0053], Fig. 4, 403 and 404).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the system of Haustein based on the teaching from Cirkic to include the features receiving, from the WD, recommended CSI feedback generation configuration parameters; and determining the updated set of CSI feedback generation configuration parameters based at least in part on the recommended CSI feedback generation configuration parameters, in order to optimize CSI reporting and overall network performance.
Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Haustein in view of Lee et al. (US 12,223,421 B2, “Lee”).
Regarding claim 6:
Haustein is silent regarding wherein the CSI feedback generation configuration is a CSI feedback generation configuration for CSI feedback using autoencoders.
Lee teaches using a CSI feedback generation configuration using autoencoders (e.g., Abtract, Column 19, 36-56, Figs. 7-13).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the system of Haustein based on the teaching from Lee to include the feature wherein the CSI feedback generation configuration is a CSI feedback generation configuration for CSI feedback using autoencoders, in order to improve spectral efficiency and overall network performance.
