Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 8-14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 8 recites the limitation "wherein a measurement of the first reference signal …; calculation of the first CQI …, the calculation of the first CQI is conditioned on a precoding matrix …, a measurement of the first reference signal is used to generate a first channel matrix, the first channel matrix being used to generate the first CQI, and the first channel matrix is unavailable for the second node". According to the claim scope “the first channel matrix is unavailable for the second node” and claim 1 recites “the first channel matrix being available only for the first node” hence all these steps are being performed on the first node.
The claim is directed towards a process performed by a second node and these limitations further describe the functions of a first node but fails to indicate how those functions further limit the process that the second node performs, as result, they are outside the scope of
the method performed by the second node.
Claim 10 recites the limitation "when the type of the first channel information is the first type, the first channel matrix is an output obtained after inputting the first channel information to a first reference decoder, the first reference decoder being available only for the first node.”. According to the claim scope the first reference decoder being available only for the first all these steps are being performed on the first node.
The claim is directed towards a process performed by a second node and these limitations further describe the functions of a first node but fails to indicate how those functions further limit the process that the second node performs, as result, they are outside the scope of
the method performed by the second node.
Claims 9, 11-14 dependent from claim 8 are indefinite for the same rationale.
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.

The AI model may include a convolutional neural network (CNN), a deep neural network (DNN), etc.);

In summary, in embodiments of the disclosure, the terminal device may calculate a CQI according to a channel matrix H and report the CQI to the network device.).

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 non-obviousness.
Claim(s) 2, 10 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over ZHOU in view of Zhu et al., US 20190036574 A1, (hereinafter Zhu).
Regarding claim 2 and 16, Zhou teaches the limitations of Claim 1 and 15.
Zhou further teaches, characterized in that when the type of the first channel information is the first type,
the first channel matrix is an output obtained after inputting the first channel information to a first reference decoder (see ¶ [0057], e.g., The terminal device may perform downlink channel estimation/measurement according to a CSI-RS to acquire a channel matrix; see ¶ [0075], e.g., The PDSCH transport block corresponds to the CQI index and occupies a CSI reference resource(s). Therefore, the CQI is associated with a performance of a PDSCH decoder selected by the terminal device.),
however, it does not explicitly teach the first reference decoder being available only for the first node.
Zhu teaches the first reference decoder being available only for the first node (see ¶ [0046], e.g., a user equipment (UE), comprising one or more baseband processors to decode one or more channel state information reference signals (CSI-RS) received from an evolved Node B (eNB) using open loop full-dimension multiple input, multiple output (FD-MIMO),).
It would have been obvious to one of ordinary skill in the art before the effective
filing date of the claimed invention to have modified decoder of Zhou to incorporate the teachings of Zhu to include first reference decoder being available only for the first node. Doing so would facilitate in achieving generating feedback to the eNB as suggested by Zhu (see ¶ [0046], e.g., to generate feedback to the eNB responsive to the one or more CSI-RS signals,).
Regarding claim 10, Zhou teaches the limitations of Claim 8.
Zhou further teaches, characterized in that when the type of the first channel information is the first type,
the first channel matrix is an output obtained after inputting the first channel information to a first reference decoder (see ¶ [0057], e.g., The terminal device may perform downlink channel estimation/measurement according to a CSI-RS to acquire a channel matrix; see ¶ [0075], e.g., The PDSCH transport block corresponds to the CQI index and occupies a CSI reference resource(s). Therefore, the CQI is associated with a performance of a PDSCH decoder selected by the terminal device.),
however, it does not explicitly teach the first reference decoder being available only for the first node.
Zhu teaches the first reference decoder being available only for the first node (see ¶ [0046], e.g., a user equipment (UE), comprising one or more baseband processors to decode one or more channel state information reference signals (CSI-RS) received from an evolved Node B (eNB) using open loop full-dimension multiple input, multiple output (FD-MIMO),).
It would have been obvious to one of ordinary skill in the art before the effective
filing date of the claimed invention to have modified decoder of Zhou to incorporate the teachings of Zhu to include first reference decoder being available only for the first node. Doing so would facilitate in achieving generating feedback to the eNB as suggested by Zhu (see ¶ [0046], e.g., to generate feedback to the eNB responsive to the one or more CSI-RS signals,).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
US 20250219693 A1 issued to Echigo et al. teaches parameter to be applied to a report of encoded channel state information (CSI).
US 20210195462 A1 issued to PEZESHKI et al. teaches measurements corresponding to at least one reference signal using an artificial intelligence (AI) encoder.
