Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Status of Claims 2. This communication is responsive to Application No. 18/861,379 filed on October 29, 2024. Claims 12-20 and 30 have been cancelled. Claims 1-11, 21-26 and 28-29 have been amended. Accordingly, claims 1-11 and 21-29 are subject to examination. Information Disclosure Statement (IDS) 3. The IDSs submitted 10/29/24 and 01/30/25 have been entered and considered by the Examiner. However, note that the IDS filed on 01/30/25 is the duplicate of the IDS filed on 10/29/24. Therefore, the IDS submitted on 10/29/24 has been “lined through”. Claim Objections/Suggestions 4. Following claims are objected to because of the following informalities: in claims 1-2, 4-6, 21-23 and 26-28 the term “predicting/predicted/predict” should be replaced with “estimating/estimated/estimate” or any other “synonym”; and “using/use” should be replaced with “utilizing/utilize”; in claim 25, line 2 “were” (line 2) should be replaced with “are”; and in claims 11 and 26, “capable of” (line 1) should be replaced with “for”. Appropriate correction is required. Claim Rejections - 35 USC § 112 5. 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. 6. Claims 1-11 and 21-29 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 pre-AIA the Applicant regards as the invention. Claim 1 recites the limitation "the measurements of the multiple CSI-RS instances" in lines 6-7. There is insufficient antecedent basis for this limitation in the claim (note: line 3 recites “measuring multiple instances of a CSI reference signal (CSI-RS)” and suggestion: “the measured multiple instances of the CSI-RS”). In addition, claim 1 recites “the linear combination coefficients” (line 8). It is not clear “the linear combination coefficients” is referring to “the estimated linear combination coefficients” (line 5); if it is, then the limitations “the SD basis, the FD basis, and the DD basis” (lines 8-9) are redundant since “linear combination coefficients” already include a combination of “a spatial domain (SD) basis, a frequency domain (FD) basis, and a Doppler domain (DD) basis” (lines 5-6). Hence, renders claim 1 and its dependent claims indefinite. Similar rejection applies to claims 11, 21 and 26. Claim 3 recites the limitation "the corresponding linear combination coefficients" in lines 2-3. There is insufficient antecedent basis for this limitation in the claim. Claim 8 recites the limitation "the measurement instances" in line 3. There is insufficient antecedent basis for this limitation in the claim. Similar rejection applies to claim 25. Reason for Allowance 7. Park (US 2025/0080175 A1) teaches in Figures 7-8 receiving and transmitting configuration information related to a CSI-RS of a wireless device and a network node and in Figure 10 a codebook (precoder) composed of combination of a SD basis and FD basis in a time domain (Doppler domain) basis. Rahman (US 2022/0329303 A1) teaches in Figures 13-20 receiving a configuration of a CSI-RS burst comprising multiple time instances of CSI-RS transmission, and a time domain (TD) unit comprising consecutive time instances; measuring the CSI-RS burst; determining, based on the measured of the CSI-RS burst and the TD unit, TD or DD components of a downlink (DL) channel; and transmitting the CSI report including an indication of the TD or DD components of the DL channel. Ren (US 2022/0094412 A1) teaches in Figure 2 a channel measurement by utilizing a SD basis, FD basis, DD basis and TD basis. 8. However, the prior art of record when implemented, would not produce said method as claimed in claims 1 and 21, said wireless device as claimed in claim 11 and said network node as claimed in claim 26. Conclusion 9. Any inquiry concerning this communication or earlier communications from the Examiner should be directed to SHAWKAT M. ALI whose telephone number is (571) 270-1639.
