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 col. 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.
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.
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.
Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Li’984 in view of Sahin et al (US20210111938A1, Priority Date: Oct 07, 2020).

Noted, trajectory matrix (Trajectory matrix used to encode multiple information bits through orthogonal/non-orthogonal chirps) may be chosen such that only one of the inputs of each DFT in the precoding matrix is non-zero and thus precoding matrix is correlated to chirp rate (each chirp signal has a different chirp rate), par 0068, 0145-0146);
wherein the OFDM-based waveform signal (OFDM symbols can be equated to OFDM-based waveform signal, par 0151) is generated from the plurality of precoded symbols (see, Fig. 22, generated signal by OFDM symbols is generated from symbols after DFT precoding operations, par 0145, 0151).

Hwang et al (US20230367005A1, PCT Priority Date: Oct 6, 2020) discloses: Complex modulation symbol sequences may be mapped to one or more transport layers by the layer mapper 330. Modulation symbols of each transport layer may be mapped (precoded) to corresponding antenna port(s) by the precoder 340. Outputs z of the precoder 340 may be obtained by multiplying outputs y of the layer mapper 330 by an N*M precoding matrix W. Herein, N is the number of antenna ports and M is the number of transport layers. The precoder 340 may perform precoding after performing transform precoding (e.g., DFT) for complex modulation symbols.
