Office Action

§102 §103
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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. This action is in response to application 18793098 filed 8/2/24. Claim(s) 1-20 is/are presented for examination. Claim Objections Claim(s) 19 is/are unclear to the examiner; what does it mean by stating “generating an angle of arrival (AoA) estimation model via deep-learning, by using, as input, a plurality of pieces of reference signal received power (RSRP) pattern training data for the plurality of candidate beams and using, as output, an AoA distribution corresponding to each of the plurality of pieces of RSRP pattern training data”? the claim languages are not very clear exactly what’s going on, to use the AoA estimation model as input and RSRP pattern training data as output? Or vice versa? Please clarify Claim Rejections - 35 USC § 102 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. Claim(s) 1-5, 7-14 & 16-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Bonfante, U.S. Pub/Patent No. US 2026/0135608 A1.

Training input data: RSRP measurements of N best SSB ( or wide) beams measured by UE at Pl, and position information of UE.

Labels- represent indices of the best gNB transmit (TX) beam and estimated AoA); generating a plurality of pieces of RSRP pattern data by measuring an RSRP in each of the plurality of candidate beams with respect to a signal received from the external device (Bonfante, page 3, paragraph 31; i.e., [0031] the node generating a sequence of beams across a range of directions or possibly covering all directions. After measuring the UE performs signal measurement (e.g., the UE measuring reference signal receive power (RSRP))); estimating an AoA distribution for each of the plurality of pieces of RSRP pattern data, by applying each of the plurality of pieces of RSRP pattern data to the AoA estimation model (Bonfante, page 5, paragraph 64; i.e., [0064] the gNB may train a ML model, to be used on or by one or more UEs. Training input data: RSRP measurements of N best SSB ( or wide) beams measured by UE at Pl, and position information of UE. The training of the ML model may use a supervised learning approach: input data (RSRP measurements of N best SSB or wide beams, and UE position infonnation) and labels (as outputs being trained), that represent value of a variable, to train the ML model parameters. Labels- represent indices of the best gNB transmit (TX) beam and estimated AoA); and performing a beam management based on the estimated AoA distribution (Bonfante, page 6, paragraph 78; i.e., [0078] AoA that most closely matches the estimated AoA of the beam output from (or predicted by) the ML model 520. There may be a different UE receive narrow beam selected or determined by the UE 512 (e.g., based on the codebook) for each of the AoAs output or predicted by the ML model 520. Thus, for example, UE 512 may select the beam of the codebook based on the minimum (or least) angular separation between the predicted Ao). Claim(s) 10-14, 16-18 is/are directed to a method/computer readable medium claims and they do not teach or further define over the limitations recited in claim(s) 1-5, 7-9. Therefore, claim(s) 10-14, 16-18 is/are also rejected for similar reasons set forth in claim(s) 1-5, 7-9. Claim(s) 19 & 20 is/are directed to a method/computer readable medium claims and they do not teach or further define over the limitations recited in claim(s) 1 & 3. Therefore, claim(s) 19 & 20 is/are also rejected for similar reasons set forth in claim(s) 1 & 3. 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 of this title, 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. Claim(s) 6 & 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bonfante, U.S. Pub/Patent No. US 2026/0135608 A1 in view of Tian, U.S. Patent/Pub. No. US 2025/0324315 A1. As to claim 6, Bonfante teaches the electronic device as recited in claim 5. But Bonfante failed to teach the claim limitation wherein each of the at least two candidate AoA classes has a matching probability with a corresponding piece of RSRP pattern data greater than or equal to a predetermined threshold in the AoA distribution (Bonfante, page 9, paragraph 177; page 10, paragraph 186; i.e., [0177] AoA that most closely matches the estimated AoA of the beam output from (or predicted by) the ML model 520. There may be a different UE receive narrow beam selected or determined by the UE 512 (e.g., based on the codebook) for each of the AoAs output or predicted by the ML model 520. Thus, for example, UE 512 may select the beam of the codebook based on the minimum (or least) angular separation between the predicted Ao). However, Tian teaches the limitation wherein each of the at least two candidate AoA classes has a matching probability with a corresponding piece of RSRP pattern data greater than or equal to a predetermined threshold in the AoA distribution (Tian, page 9, paragraph 177; page 10, paragraph 186; i.e., [0177] a target accuracy threshold is less than a first threshold; or that the performance of the positioning scheme based on AI and/or ML is a second performance if the probability that the positioning accuracy from the output result of the communication scheme is greater than the target accuracy threshold is greater than a second threshold; [0186] a beam selection scheme (e.g., an AI and/or ML scheme for processing beam selection) is a first performance if at least one of an RSRP difference, an RSRQ difference, an SINR difference, or a beam angle difference between the selected beam obtained from the output result of the communication scheme and the target beam is greater than a first threshold; or that the performance of the beam selection scheme is a second performance if at least one of the RSRP difference, the RSRQ difference, the SINR difference, or the beam angle difference between the selected beam obtained from the output result of the communication scheme and the target beam is less than a second threshold). It would have been obvious to one of ordinary skill in the art before the effective date of the claimed invention to modify Bonfante to substitute non-terrestrial communication networks from Tian for cellular network from Bonfante to meets a performance monitoring condition (Tian, page 1, paragraph 5). Claim(s) 15 is/are directed to a method claim and they do not teach or further define over the limitations recited in claim(s) 6. Therefore, claim(s) 15 is/are also rejected for similar reasons set forth in claim(s) 6. Listing of Relevant Arts Bai, U.S. Patent/Pub. No. US 20240039606 A1 discloses measuring and reporting RSRP and identifying AoA. Ma, U.S. Patent/Pub. No. US 20220007346 A1 discloses probability threshold and target beam.
