Response to Arguments
Applicant’s Amendments and Arguments filed 07/23/2026 have been considered for examination.
With regard to the 103 rejections, Applicant’s arguments filed 07/23/2026 in view of the amendments have been fully considered but are not persuasive at least in view of reasons set forth below.
On page 10 of Remarks, Applicant argued:
Chavva does not disclose beam quality corresponding to M second RS identifiers whose
beam quality is not reported. Although Chavva discloses computing or predicting feedback
parameters using an AI network, Chavva does not disclose beam quality corresponding to RS
identifiers whose beam quality is not reported. Therefore, Chavva fails to disclose "beam quality
corresponding to M second RS identifiers, wherein the M second RS identifiers are RS identifiers whose beam quality is not reported," as required by amended independent claim 1.
Guo does not cure this deficiency of Chavva. Guo discloses that a UE may report selected
RS IDs and corresponding Ll-RSRP measurements. See Guo, para. [0236]. Thus, the beam quality corresponding to the selected RS IDs in Guo is reported. Guo does not disclose beam quality corresponding to M second RS identifiers whose beam quality is not reported. Therefore, Guo also fails to disclose "beam quality corresponding to M second RS identifiers, wherein the M second RS identifiers are RS identifiers whose beam quality is not reported," as required by
amended independent claim 1.
In response to the above Applicant’s argument, Examiner respectfully disagrees.
Unlike the applicant’s arguments above, Guo clearly discloses, "beam quality
corresponding to M second RS identifiers, wherein the M second RS identifiers are RS identifiers whose beam quality is not reported," as required by amended independent claim 1.
The claimed features of claim 1 require two types of beam qualities which correspond to a “first RS identifiers” and “M second RS identifiers”, respectively. Further, the claimed feature requires that the beam quality of the M second RS identifiers are not reported and M is a positive integer.
Guo states:
[0136] CSI configuration framework, the UE can be configured with higher layer parameter ReportQuantity set to be “CRI/RSRP” or “SSBRI/RSRP”. When the UE is configured with “CRI/RSRP”, the UE can be requested to report N different CRIs and their corresponding L1-RSRP based one measuring K configured CSI-RS resources. An example of K value is 16, 32 or 64. When the UE is configured with “SSBRI/RSRP”, the UE can be requested to report N different SSBRIs and their corresponding L1-RSRP values. The example of N can be 1, 2, 3, and 4. (Emphasis added.)
Based on reading “CRI” and “RSRP” of Guo can be interpreted as the claimed “RS identifiers” and “beam quality”, respectively, [0136] of Guo discloses that N different CRIs (i.e., first RS identifiers) corresponding to their L1-RSRPs (i.e., beam qualities of the first RS identifiers) are selected and reported from K measured CSI-RS resources.
Here, since N can be “1, 2, 3, and 4” and K can be “16, 32 and 64”, there should be (K-N) CRIs and their corresponding L1-RSRPs which are measured by the UE, but are NOT part of the selected N CRIs and their corresponding L1-RSRPs. The (K-N) CRIs and their corresponding L1-RSRPs can be interpreted as the claimed “M second RS identifiers” and their corresponding “beam quality”.
On page 10 of Remarks, Applicant argued:
Islam was cited only in the rejection of original claim 11 and does not disclose the above recited limitation. In particular, Islam does not disclose beam quality corresponding to M second RS identifiers whose beam quality is not reported. Accordingly, Islam does not cure the deficiencies of Chavva and Guo.
In response to the above Applicant’s argument, Examiner respectfully disagrees.
Since claims 1, 15 and 19 are unpatentable over Chavva and Guo as set forth above, thus the other cited references do not necessarily be considered regarding patentability of the claims.
On page 10 of Remarks, Applicant argued:
Independent claims 15 and 19 are likewise allowable over Chavva, Guo, and Islam because they each recite similar claim limitations as those of independent claim 1.
In response to the above Applicant’s argument, Examiner respectfully disagrees.
Since claims 15 and 19 recite similar features to claim 1 without further patentable features, claims 15 and 19 are unpatentable in view of the same reasons set forth above regarding claim 1.
On page 11 of Remarks, Applicant argued:
Dependent claims 2, 4-14, 16, 18, and 20 are thus allowable over these cited references at least by virtue of their dependencies from their respective base claims 1, 15, or 19, and because they each recite additional distinct limitations.
In response to the above Applicant’s argument, Examiner respectfully disagrees.
Since claims 2, 4-14, 16, 18, and 20 are unpatentable over the cited references of record as set forth above, patentability of other dependent claims should be determined based on the claimed limitations recited thereon, rather than their respective independent claims. The dependent claims are also unpatentable in view of the corresponding cited references of records as set forth below.
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 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.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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 nonobviousness.
Claims 1-2, 4-10, 12-16 and 18-22 are rejected under 35 U.S.C. 103 as being unpatentable over Chavva et al (US Publication No. 2021/0351885) in view of Guo et al (US Publication No. 2019/0190582).

The example of N can be 1, 2, 3, and 4; note that since N can be “1, 2, 3, and 4” and K can be “16, 32 and 64”, there should be (K-N) CRIs and their corresponding L1-RSRPs which are measured by the UE, but are NOT part of the selected N CRIs and their corresponding L1-RSRPs. The (K-N) CRIs and their corresponding L1-RSRPs can be interpreted as the claimed “M second RS identifiers” and their corresponding “beam quality”].
It is noted that the above-mentioned feature is a known technique in the field Applicant's endeavor, e.g., telecommunication art.
It is noted that the above-mentioned feature is a known technique in the field Applicant’s endeavor, e.g., telecommunication art. It would have been obvious to one having ordinary skill in the art before the effective filing date to combine the system of Chavva with "the above-mentioned known feature(s)" taught by Guo to reach the claimed invention as set forth above. Since one having ordinary skill in the art could have recognized that applying the known technique taught by Guo into the system of Chavva would have yield predictable results and/or resulted in the improved system, such as e.g., ensure to enable optimal beam selection and maintain reliable high-quality communication by allowing the network to adapt to channel condition dynamically, such a modification (or application) would have involved the mere application of a known technique to a piece of prior art ready for improvement," the claim is unpatentable under 35 U.S.C. 103(a).

It is noted that the above-mentioned feature is a known technique in the field Applicant's endeavor, e.g., telecommunication art.
It would have been obvious to one having ordinary skill in the art before the effective filing date to combine the system of Chava in view of Guo with "the above-mentioned known feature(s)" taught by Islam to reach the claimed invention as set forth above. Since one having ordinary skill in the art could have recognized that applying the known technique taught by Islam into the system of Chava in view of Guo would have yield predictable results and/or resulted in the improved system, such as e.g., ensure the base station assess channel quality variation and adjust link adaption or beam management strategies for more stable and efficient communication, such a modification (or application) would have involved the mere application of a known technique to a piece of prior art ready for improvement," the claim is unpatentable under 35 U.S.C. 103(a).
