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.

Claim(s) 1,5,10,13,16,21-22,24,30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wei to (WO2020/142974 A1) from IDS in view of MURUGANATHAN to (WO 2022009178 A1)
Regarding claims 1,10,16,22,30 Wei teaches an information reporting method, comprising: estimating, by a terminal, downlink channel information;( [0058], fig. 3, "As shown in Fig. 3, and by reference number 305, the BS 110 may transmit reference signal transmissions to the UE 120.[...] the UE 120 may perform channel estimation or another operation
based at least in part on the reference signal transmissions in order to
determine CSI feedback") determining, by the terminal, frequency-domain basis vector information in accordance with the downlink channel information; ( [0058] and [0060], fig. 3, "As shown in Fig. 3, and by reference number 305, the BS 110 may transmit reference signal transmissions to the UE 120. [...] the UE 120 may perform channel estimation or another operation based at least in part on the reference signal transmissions in order to determine CSI feedback", and "As shown by reference number 320, the UE may transmit CSI feedback based at least in part on the set of non-zero FD complex coefficients. The CSI feedback is described in more detail in connection with [...] reference numbers 345 through 365 (e.g., the second part of the CSI feedback) ") transmitting, by the terminal, the frequency-domain basis vector information to a network device ( [0065], "As shown by reference number 355, the second part may identify a selected FD basis vector subset".. [0079], "a second part of the CSI feedback includes: a first index identifying a particular frequency domain basis vector of a selected subset of frequency domain basis vectors, and a second index identifying remaining frequency domain basis vectors of the selected subset of frequency domain basis vectors")
Wei does not explicitly teach receiving, by the terminal, a set of frequency-domain basis vectors configured by the network device; determining, by the terminal, the frequency-domain basis vector information in accordance with the set of frequency-domain basis vectors
However, MURUGANATHAN teaches receiving, by the terminal, a set of frequency-domain basis vectors configured by the network device; ([0237] Embodiment 54: A method for signaling to a user equipment, UE, from a network (e.g., eNB) a selected subset of frequency domain, FD, basis vectors among a full set, N.sub.3, of FD basis vectors. The FD basis vectors comprise a set of orthogonal complex vectors having a length that equals N.sub.3. The method comprising the UE using the selected subset of FD basis vectors to compute a CSI corresponding to an enhanced (e.g., 3GPP Rel-16) type II port selection codebook) determining, by the terminal, the frequency-domain basis vector information in accordance with the set of frequency-domain basis vectors([0240] … The MAC CE is configured to indicate up to a maximum number of FD basis vectors. [0241] .. The maximum number of FD basis vectors is determined via one or more higher layer configured parameters. [0242] … The selected subset of FD basis vectors is signaled via downlink control information, DCI. [0243] … The UE computes the CSI using all of the selected FD basis vectors. [0244] … The UE does not feedback report indices 7.sub.",e and 7.sub.",^,^ as part of an enhanced type II port selection PMI report. [0245] … The UE computes the CSI using a subset of the selected FD basis vectors. [0246] … The UE reports one or more of the indices 7.sub.",e and 7.sub.",^,^ as part of an enhanced type II port selection PMI report)
Therefore; it would have been obvious to one ordinarily skilled in the art before the effective filing date of the claimed invention to enable the system of Wei include
receiving, by the terminal, a set of frequency-domain basis vectors configured by the network device; determining, by the terminal, the frequency-domain basis vector information in accordance with the set of frequency-domain basis vectors, as suggested by MURUGANATHAN. This modification would benefit the system to efficiently utilize available the network resources.
Regarding claims 5,13,21,24 Wei teaches wherein the frequency-domain basis vector information comprises indication information corresponding to the frequency-domain basis vector ([0079], "a second part of the CSI feedback includes: a first index identifying a particular frequency domain basis vector of a selected subset of frequency domain basis vectors, and a second index identifying remaining frequency domain basis vectors of the selected subset of frequency domain basis vectors")wherein the indication information corresponding to the frequency-domain basis vector is used to indicate a frequency-domain basis vector selected by the terminal, a frequency-domain basis vector selected by the terminal in a set of frequency-domain basis vectors predetermined in the terminal([0079], "a second part of the CSI feedback includes: a first index identifying a particular frequency domain basis vector of a selected subset of frequency domain basis vectors, and a second index identifying remaining frequency domain basis vectors of the selected subset of frequency domain basis vectors")

Each Codebook Configuration represents at least one codebookType Codebook type, which includes indicators representing at least one or more of a CSI-RS Resource Indicator (“CRI”), a Synchronization-Signal Block Resource Indicator (“SSBRI”), a Rank Indicator (“RI”), a Precoding Matrix Indicator (“PMI”))
determining, by the terminal, the codebook parameter in accordance with the triggering
state( [0133] discloses multi-TRP transmission may be indicated to the UE via triggering two CodebookConfig codebook configurations within one Reporting Setting, each corresponding to one or more CSI Reports. An example of the ASN.1 code the corresponds to the CSI-ReportConfig Reporting Setting IE is provided in Figure 7D, wherein two codebook configurations 710, 712 are triggered under the same Reporting Setting)
