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 .
Response to Arguments
Applicant's arguments filed January 20, 2026 have been fully considered but they are not persuasive.
Applicants submit that Sosnin does not teach or suggest any "quantity of paths indicated via the per-path angle of arrival reporting configuration." For example, at the portions cited by the Office Action, Sosnin describes “configuration information that a user equipment (UE) is to use to perform a multi-path channel component measurement.” However, the configuration information of Sosnin does not describe any “quantity of paths”.
Examiner submits that Sosnin teaches that the maximum number of paths to report can be configured by gNB/network through RRC/LPP/LPPa or NRPP/NRPPa signaling (Paragraph 0077). Sosnin further teaches of selecting a subset of the plurality of paths (first detected arrival path and N strongest paths which power is above predefined threshold, Paragraph 0080) that comprises the quantity of paths indicated via the per-path angle of arrival reporting configuration (N+1 paths, Paragraphs 0077 – 0080). Therefore, Sosnin, Cha, Kim, Nilsson and Kim(2) teach all the limitations of claim 1.
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 nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.

Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Sosnin, Cha, Kim, Nilsson and Kim(2) in view of Pan and further in view of Schier et al (US 2016/0135146).
Re claim 21, Sosnin, Cha, Kim, Nilsson and Kim(2) teach all the limitations of claim 16 except of transmitting a group configuration indicating a group identifier of a group of UEs including the UE based at least in part on receiving the feedback report; transmitting, based at least in part on the group configuration, a control transmission that indicates the group identifier and includes a grant scheduling a group transmission; and transmitting a data transmission based at least in part on the grant.
Pan teaches of transmitting a group configuration indicating a group identifier of a group of UEs including the UE (Fig.12, Paragraph 0186) based at least in part on transmitting the feedback report (Paragraphs 0105, 0120 and 0139).
Schier teaches of further comprising: transmitting the control transmission that indicates the group identifier and includes the grant (Paragraph 0028, Figures 1 – 4); and receiving a data transmission based at least in part on the grant (uplink transmission, Abstract and Paragraph 0029).
lt would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have transmitted a group configuration that indicate a group identifier of a group of UEs for improved beam management. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have performed control transmission and data transmission based at least in part on the grant for enhanced transmission efficiency.
Claims 14 and 24 are rejected under 35 U.S.C. 103 as being unpatentable over Sosnin, Cha, Kim, Nilsson and Kim(2) in view of Li et al (US 2021/0297123).
Re claims 14 and 24, Sosnin, Cha, Kim, Nilsson and Kim(2) teach all the limitations of claims 1 and 16 except of wherein transmitting the feedback report comprises: transmitting (receiving) the feedback report in a medium access control (MAC) control element, an uplink control channel transmission, an uplink radio resource control message, or a combination thereof.
Li teaches of transmitting (receiving) a feedback report comprises: transmitting the feedback report in a medium access control (MAC) control element, an uplink control channel transmission, an uplink radio resource control message, or a combination thereof (Paragraph 0002).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have transmitted (received) the feedback report in an uplink control channel transmission for providing the feedback report to the base station.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
