Claim Rejections - 35 USC § 103
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.
Claims 6, 10, 11 are rejected under 35 U.S.C. 103 as being unpatentable over Nam in view of Rahman et al. (US 20230318793 A1), hereinafter Rahman.
Regarding claim 6, Nam fails to teach,
The UE of claim 3, wherein the second basis transformation corresponds to a same type of the third basis transformation, the third basis transformation transforming the second dimension into a lesser number of indices than the second basis transformation.
However, Rahman teaches,
The UE of claim 3, wherein the second basis transformation corresponds to a same type of the third basis transformation, the third basis transformation transforming the second dimension into a lesser number of indices than the second basis transformation. (paragraphs 0240-0246 – DD compression can be turned on from the codebook configuration causing the basis vector to not be reported).
It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Nam to incorporate the lesser number of indices than the second basis transformation teachings of Rahman. The purpose of doing so is to allow for a reporting parameter to be turned off depending on the codebook type and port selection being used (paragraph 0245).
Regarding claim 10, Nam fails to teach,
The UE of claim 2, wherein the instructions are executable by the processor to cause the UE to represent coefficients associated with a first subset of the two subsets of coefficients with a distinct codebook of quantized values,
and wherein a number of bits associated with quantizing a coefficient associated with the first subset of the two subsets of coefficients is larger than a number of bits associated with quantizing a coefficient associated with a second subset of the two subsets of coefficients.
However, Rahman teaches,
The UE of claim 2, wherein the instructions are executable by the processor to cause the UE to represent coefficients associated with a first subset of the two subsets of coefficients with a distinct codebook of quantized values, (paragraphs 0258-0271 – A new codebook which provides coefficients including amplitude and phase coefficients (paragraphs 0264, 0265) for subsets W1 and Wf, the number of bits is smaller indicating a decreased reporting payload from the first codebook (paragraph 0271)).
and wherein a number of bits associated with quantizing a coefficient associated with the first subset of the two subsets of coefficients is larger than a number of bits associated with quantizing a coefficient associated with a second subset of the two subsets of coefficients. (paragraph 0271 - the number of bits is smaller indicating a decreased reporting payload from the first codebook).
It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Nam to incorporate the subset of coefficients associated with a distinct codebook of values teachings of Rehman. The purpose of doing so is to increase transmission reporting payload by allowing for less bits to be used for a second CSI report compared to a first CSI report (paragraph 0271).
Regarding claim 11, Nam fails to teach,
The UE of claim 2, wherein the instructions are executable by the processor to cause the UE to configure the UE with a higher-layer parameter within the CSI reporting setting that enables or disables reporting of a first subset of the two subsets of coefficients.
However, Rahman teaches,
The UE of claim 2, wherein the instructions are executable by the processor to cause the UE to configure the UE with a higher-layer parameter within the CSI reporting setting that enables or disables reporting of a first subset of the two subsets of coefficients. (paragraph 0240-0245 – The reporting of the CSI can be turned off or disabled for Wd which is the basis matrices of the third dimension.)
It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Nam to incorporate the enabling or disabling of reporting of a first subset of the two subsets of coefficients teachings of Rahman. The purpose of doing so is to allow for a reporting parameter to be turned off depending on the codebook type and port selection being used (paragraph 0245).
