Office Action

§101 §112
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 . This office action is in response to preliminary amendments submitted on 7/19/2024. Claims 1-14, 17-22 have been amended. Claims 15-16 have been cancelled. Claim Objections Claim 14 is objected to because of the following informalities: Claim 14 recites “a number of transmission antennas and a modulation order” should be “the number of transmission antennas and the modulation order” as recited in claim 12. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 6,13-14,17-18 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 6 recites the limitation "the training transmission signal" in page 6. There is insufficient antecedent basis for this limitation in the claim. Claim 6 further recites the limitation "the training receipt signal" in page 6. There is insufficient antecedent basis for this limitation in the claim. Claim 13 recites the limitation "the first intermediate value" in page 8. There is insufficient antecedent basis for this limitation in the claim. Claim 13 further recites the limitation "the second intermediate value" in page 8. There is insufficient antecedent basis for this limitation in the claim. Claim 14 is also rejected to as being dependent upon a rejected base claim. Claim 17 recites the limitation "the apparatus " in page 8. There is insufficient antecedent basis for this limitation in the claim. Claim 18 recites the limitation "the apparatus " in page 9. There is insufficient antecedent basis for this limitation in the claim. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 17-18, 21-22 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim does not fall within at least one of the four categories of patent eligible subject matter (process, machine, manufacture or composition of matter) because: Claims 17-18 recite “computer program" which covers forms of non-transitory tangible media and software per se in view of the ordinary and customary meaning of computer program distribution media. Claims 21-22 recite “computer-readable storage medium" which covers forms of non-transitory tangible media and transitory propagation signals per se in view of the ordinary and customary meaning of computer readable distribution media. Allowable Subject Matter Claims 1-5,7-12,19-20 are allowed. Claims 6,13 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claim 14 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. In addition, the claim objection needed to be overcome. Reclaims 1-10,17,19,21 Prior art reference failed to teach or disclose obtaining a first matrix and a first vector by performing data preprocessing on the channel matrix; and obtaining an estimated detection signal by inputting the first matrix and the first vector to a trained deep learning model, wherein the trained deep learning model comprises N trained convolutional network models, N being a positive integer and being equal to a number of transmission antennas. Reclaims 11-14,18,20,22 Prior art reference failed to teach or disclose method of signal detection, performed by a terminal device, the method comprising: sending a signal and an intermediate parameter, wherein the intermediate parameter is obtained by training a meta-learning parameter learning model based on network fusion. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Prior art reference Rawat (et al. US 2022/0188690) discloses machine learning security treat detection using meta-learning model. Prior art reference Hoydis (et al. US 2023/0082536) discloses fast retraining of full fused neural transceiver.
