2c. Claim Analysis
Regarding Claim 1, Kwak discloses:
A method for feeding back channel state information (Fig 26), comprising:
performing sampling (Fig 26, Step 2640; see: [0130] … LTE also provides a codebook subsampling function for periodic CSI reporting) on initial channel information (see: [0130] … various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2; Examiner’s Note: RI, wCQI, OMI1, … are initial channel information before sampling) to obtain check information (see: [0130] … various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2 may be transmitted on the PUCCH through subsampling; Examiner’s Note: the sampled feedback objects may function as check information);
and feeding back the check information (Fig 26, Steps 2650, TRANSMIT FEEDBACK INFORMATION …).
Regarding Claim 2, Kwak discloses:
acquiring first type codebook information (Table 29, Codebook Types; see: [0169] … Type I CSI reporting can report the channel state to an eNB through RI, PMI, CQI, and CSI-RS resource indicator (CRI) based on codebook as in LTE; Examiner’s Note: channel state information is encoded with a specific type of codebook, and functions as first type codebook information) according to the initial channel information (see: [0130] … various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2, before sampling);
and feeding back the first type codebook information (Fig 26, Steps 2650, TRANSMIT FEEDBACK INFORMATION …).
Regarding Claim 3, Kwak discloses:
wherein, performing joint encoding (Table 10, Joint Codebook; see: [0131] … when the number of CSI-RS ports set by the eNB is 8, an RI and a PMI1 reported in a submode 1 of a PUCCH mode 1-1 can be jointly encoded as shown in Table 10 below) on the check information (see: [0130] … various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2 may be transmitted on the PUCCH through subsampling; Examiner’s Note: the encoded sampled feedback objects may function as check information) and the first type codebook information (Table 29, Codebook Types; see: [0169] … Type I CSI reporting can report the channel state to an eNB through RI, PMI, CQI, and CSI-RS resource indicator (CRI) based on codebook as in LTE; Examiner’s Note: channel state information is encoded with a specific type of codebook, and functions as first type codebook information) in a same coding block to obtain joint encoded information; and (Table 10, Joint Codebook; see: [0131] … when the number of CSI-RS ports set by the eNB is 8, an RI and a PMI1 reported in a submode 1 of a PUCCH mode 1-1 can be jointly encoded as shown in Table 10 below);

Regarding Claim 4, Kwak discloses:
wherein a feedback priority (Table 29, Codebook Types; see: [0237] Priority determination method 4: priority of CSI reporting and/or beam management information is determined according to the codebook type) of the check information is not higher than a feedback priority of the first type codebook information (see: [0268] In this manner, the Type II CSI reporting requires higher UE complexity than the Type I CSI reporting, and thus, contains more information. Therefore, by allowing the UE to prioritize the Type II CSI reporting, the eNB may acquire a larger amount of information. Examiner’s Note: first type codebook contains more information than check information, and has higher priority).

Claim Rejections - 35 USC § 103
2. 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.
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 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.
3a. Claims 14 are rejected under 35 U.S.C. 103 as being unpatentable over Kwak (US 20190215086 A1) in view of Chen (US 20260012236 A1).
3b. Summary of the Cited Prior Art
Kwak discloses a method for CSI reporting in communication system.
Chen discloses a method for codebook sampling for CSI feedback.
3c. Claim Analysis
Regarding Claim 14, Kwak discloses:
A method for processing feedback information (Fig 27), comprising:
receiving (Fig 27, Step 2730) check information (see: [0130] … Because an amount of information that can be transmitted at one time through the PUCCH is limited, various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2 may be transmitted on the PUCCH through subsampling; Examiner’s Note: the sampled feedback objects may function as check information);
receiving (Fig 27, Step 2730) first type codebook information (Table 29, Codebook Types; see: [0169] … Type I CSI reporting can report the channel state to an eNB through RI, PMI, CQI, and CSI-RS resource indicator (CRI) based on codebook as in LTE; Examiner’s Note: channel state information is encoded with a specific type of codebook, and functions as first type codebook information);
performing processing (Fig 27, Step 2730; see: [0318] In step 2730, the eNB receives feedback information from the UE at a predetermined timing; Examiner’s Note: eNB starts processing the feedback information as implied) on the first type codebook information to obtain verification information (see: [0015] … The CSI reporting is identified based on types of CSI reportings; Examiner’s Note: CSI identifier may function as verification information) corresponding to the check information (see: [0130] … various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2 may be transmitted on the PUCCH through subsampling; Examiner’s Note: the sampled feedback objects may function as check information);
and determining a network performance identifier (see: [0013] …. the CSI can be efficiently identified despite a limited amount of information being used for the CSI reporting; Examiner’s Note: CSI identifier may function as network performance identifier) according to the verification information (see: [0015] … The CSI reporting is identified based on types of CSI reportings; Examiner’s Note: CSI identifier may also function as verification information) and the check information (see: [0130] … various feedback objects, such as RI, wCQI, sCQI, PMI1, wPMI2, and sPMI2 may be transmitted on the PUCCH through subsampling; Examiner’s Note: the sampled feedback objects may function as check information).
Kwak discloses receiving feedback (Fig 27, Step 2730), but does not discloses receiving check information and first type codebook information separately and sequentially.
However, Chen discloses transmitting and receiving CSI reports separately based on the codebooks and reporting types:
receiving check information (Fig 4B, Report 1 RI; Table 1; see: [0029] If PUCCH mode 2-1 is selected in block 202, then block 207 generates report 1 comprising RI and a precoding type indicator (PTI));
receiving first type codebook information (Fig 4B, Report 2 W1/W2/CQI; Table 1; see: [0029] … If PTI=0, then block 210 generates report 2 comprising a wideband W1, …).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to integrate Kwak’s method for CSI reporting in communication system with Chen’s method for codebook sampling for CSI feedback with the motivation being to improve spectral efficiency (Chen, [0006]).
Regarding Claim 18, the claim discloses similar features as of Claim 14, and is rejected accordingly. Further, Kwak discloses I/O transceiver, processor and memory in control unit (Figs 28-29).
Regarding Claim 19, the claim discloses similar features as of Claim 14, and is rejected accordingly. Further, Kwak discloses I/O transceiver, processor and memory in control unit (Figs 28-29).
Regarding Claim 20, the claim discloses similar features as of Claim 1 or 14, and is rejected accordingly. Further, Kwak discloses I/O transceiver, processor and memory in control unit (Figs 28-29).
