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 (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.
The factual inquiries 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.
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.
2. Claims 10, 12-13 are rejected under 35 U.S.C. 103 as being unpatentable over Tang et al. US 20250233602 hereafter Tang in view of ATZENI et al. US 20240129856 hereafter Atzeni.
As to Claim 10. Tang discloses the first radio node [i.e. Apparatus-302] of claim 1 [Fig. 5, Section 0089],
Tang doesn’t explicitly state wherein one or more of: transmission of the one or more reference signals at a symbol including an inverse Fast Fourier Transform (IFFT) stage includes shaping dedicated REs for time-domain shaping; or transmission of the one or more reference signals at a symbol including an IFFT stage includes adjusting an IFFT length to a reference signal duration and multiplexing the one or more reference signals at a post-IFFT stage.
However, Atzeni teaches wherein one or more of: transmission of the one or more reference signals at a symbol including an inverse Fast Fourier Transform (IFFT) stage includes shaping dedicated REs for time-domain shaping; or transmission of the one or more reference signals at a symbol including an IFFT stage includes adjusting an IFFT length to a reference signal duration and multiplexing the one or more reference signals at a post-IFFT stage [Fig. 24 (Illustrates representation of FFT in the case of two devices), Sections 0002, 0008, 0166: To meet the quality-of-service requirements, the power consumed by each analog-to-digital/digital-to-analog converter (ADC/DAC) scales with the sampling rate and number of quantization bits suggests adopting low-resolution ADCs/DACs with quantization bits and multiplexing gains by multiple-input multiple-output (MIMO). A channel transmission is associated with reference signals and power level. FFT is used in the case of two devices with delayed signals according to an example].
Therefore, it would have been obvious to one skilled in the art before the effective filing date to have combined the methods of Tang relating to device relating to low bit resolutions and sampling rates relating to ADC/DAC with the teaching of Atzeni relating to applying FFT, channel transmission are generally associated with reference signals and used with devices. By combining the method/systems, FFT can be applied with reference signals for adopting low resolution thereby saving power when performing ADC/DAC as suggested by Atzeni.
As to Claim 12. Tang discloses the first radio node of claim 1, wherein the at least one processor is configured to cause the first radio node to [Fig. 5, Section 0089]:
Tang doesn’t explicitly state generate the one or more reference signals using a digital quantization step from one or more supported digital quantization steps of the first radio node.
However, Atzeni teaches generate the one or more reference signals using a digital quantization step from one or more supported digital quantization steps of the first radio node [Sections 0002, 0051, 0117: There are fully digital antennas at the gNB to use for each analog-to-digital/digital-to-analog converter (ADC/DAC) scales linearly with the sampling rate and exponentially with the number of quantization bits. Each signal sequence may comprise reference signal sequence. Network node device herein can apply ADCs/DACs with 2 to 4 quantization bits].
Therefore, it would have been obvious to one skilled in the art before the effective filing date to have combined the methods of Tang relating to device relating to low bit resolutions and sampling rates relating to ADC/DAC with the teaching of Atzeni relating network node to applying digital quantization with reference signals. By combining the method/systems, the network node/radio node can apply digital quantization with the reference signals with its digital antennas without undue experimentation.
As to Claim 13. Tang discloses the first radio node of claim 1, wherein the at least one processor is configured to cause the first radio node to [Fig. 5, Section 0089]:
Tang doesn’t explicitly state generate the one or more reference signals using digital quantization at one or more of: after an inverse Fast Fourier Transform (IFFT) stage and prior to cyclic prefix (CP) insertion; after the IFFT stage and after CP insertion; after an up sampling and filtering stage; or after a reference signal generated in time domain.
However, Atzeni teaches generate the one or more reference signals using digital quantization at one or more of: after an inverse Fast Fourier Transform (IFFT) stage and prior to cyclic prefix (CP) insertion; after the IFFT stage and after CP insertion; after an up sampling and filtering stage; or after a reference signal generated in time domain [Fig. 24 (Illustrates representation of FFT in the case of two devices), Sections 0002, 0051, 0117, 0166: There are fully digital antennas at the gNB to use for each analog-to-digital/digital-to-analog converter (ADC/DAC) scales linearly with the sampling rate and exponentially with the number of quantization bits. Each signal sequence may comprise reference signal sequence. Network node device herein can apply ADCs/DACs with 2 to 4 quantization bits. FFT used after removing the cyclic prefix (CP)].
Therefore, it would have been obvious to one skilled in the art before the effective filing date to have combined the methods of Tang relating to device relating to low bit resolutions and sampling rates relating to ADC/DAC with the teaching of Atzeni relating to applying FFT, channel transmission are generally associated with reference signals and used with devices and network node applying digital quantization with reference signals. By combining the method/systems, FFT can be applied with reference signals for adopting low resolution and the network node/radio node can apply digital quantization with the reference signals with its digital antennas without undue experimentation.
