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 (i.e., changing from AIA to pre-AIA ) 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, 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.
Claims 1 is rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US# 2022/0345340 hereinafter referred to as Kim) in view of Wang (US# 2026/0121819).
RE Claim 1, Kim discloses an operating method of a receiver that communicates with a transmitter through a frequency band (See Kim [0010], [0013] -determining frequency offsets in a wireless communication system), the operating method comprising:
detecting a signal received from the transmitter at a plurality of sub-bands constituting the frequency band (See Kim [0010], [0013] – receiving signal from transmitter; for each segment in the plurality of segments);
determining first frequency offsets for the signal at reception sub-bands at which the signal has been detected among the plurality of sub-bands (See Kim [0010], [0013] - for each segment in the plurality of segments, applying a transform to a given segment and stacking results from the transform to build a first two dimensional matrix, such that the transform analyzes frequency content of the given segment, wherein one dimension in the first matrix corresponds to a carrier frequency within a range of possible carrier frequency offsets and other dimension in the first matrix corresponds to a different segment in the plurality of segments); and
determining second frequency offsets by calibrating carrier frequency offsets (See Kim [0010], [0013] - for each carrier frequency in the range of possible carrier frequency offsets, applying the transform to data associated with a given carrier frequency and thereby generate a second two dimensional matrix, where one dimension in the second matrix corresponds to a carrier frequency within a range of possible carrier frequency offsets and other dimension in the second matrix corresponds to a frequency in a range of possible sampling frequency offsets).
Kim does not specifically disclose determining the second frequency offset by calibrating carrier frequency offsets based on a distance of each of the reception sub-bands from a center frequency of the frequency band.
However, Wang teaches of determining a frequency offset by calibrating carrier frequency offsets based on a distance of each of the reception sub-bands from a center frequency of the frequency band (See Wang [0003]-[0007] – determining frequency offset based on distance from center frequency of sub-band and center frequency of carrier frequency).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, as disclosed in Kim, comprising determining the second frequency offset by calibrating carrier frequency offsets based on a distance of each of the reception sub-bands from a center frequency of the frequency band, as taught in Wang.

the determining of the first frequency offsets comprises determining the first frequency offset based on periodicity of the training sequence (See Wang ‘947 [0012], [0093], [0100], [0102] - the AP may perform conjugate multiplication of training data on at least two HELTF symbols with same training data to obtain a phase value, and then determine the frequency offset value between the AP and the STA based on the phase value and the periodicities of the HELTF symbols).

However, Qian teaches of wherein the distance of each of the reception sub-bands from the center frequency of the frequency band corresponds to a magnitude of an index of each of the reception sub-bands (See Qian [0192]-[0193] – determining the positions of the edge reference signals according to the received subband center frequency point includes determining the initial position of the edge reference signals of the UE, and calculating the offset of the positions of the reference signal compared to the initial position according to the center frequency point following T.sub.edge=mod(N.sub.c,2), wherein N.sub.c denotes the index of current subband counted from edge of system available frequency band).
