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.

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 10 and 28 are rejected under 35 U.S.C. 103 as being unpatentable over Ren in view of Zhang et al (US20230031360A1) (hereinafter "Zhang").
Regarding claim 10, Ren fails to disclose the apparatus, wherein the slot including the first instance is a starting slot for the first bin of the codebook.
However, Zhang discloses the apparatus, wherein the slot including the first instance is a starting slot for the first bin of the codebook ([0125] Example 18 includes the subject matter of any one of examples 1-10, including or omitting optional elements, wherein the one or more processors are configured to cause the device to: determine a first candidate size of the HARQ codebook for each slot based on a number of active SPS PDSCH configurations in the slot for all component carriers; divide a start and length indicator value (SLIV) table into a number of segments based on a length of a smallest SPS PDSCH reception in the determined set of SPS PDSCH receptions; determine a second candidate size of the HARQ codebook for each slot based on the number segments; and determine the size of the HARQ codebook for each slot as the smaller of the first candidate size and the second candidate size.).
Ren and Zhang are considered to be analogous to the claimed invention because both are in the same endeavor of optimizing and constraining the size a codebook.
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Ren with Zhang to create the apparatus, wherein the slot including the first instance is a starting slot for the first bin of the codebook.
The motivation to combine both references would come from the need to prevent excessive feedback overhead.
Regarding claim 28, Ren fails to disclose the apparatus, wherein the slot including the first instance is a starting slot for the first bin of the codebook.

Claims 11 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Ren in view of Yu et al (US20160072565A1) (hereinafter "Yu").
Regarding claim 11, Ren fails to disclose the apparatus, wherein an observation window associated with the CSI report has a length equal to a time length for the codebook.
However, Yu discloses the apparatus, wherein an observation window associated with the CSI report has a length equal to a time length for the codebook ([0093] Here, the size of a codebook of W2 should be equal to or less than a size capable of being indicated by a precoder indicator. For example, in the current LTE system, the base station may indicate one precoder of 16 candidates to the UE by using TPMI having a 4-bit length. Therefore, if a precoder indicator is formed of N bits, a precoder of a W2 codebook should be 2.sup.N or less. At step 830, the UE finds a recent aperiodic CSI report containing RI which is set to use the same W1 precoder as that of rank which is set (or scheduled) by the base station.).
Ren and Yu are considered to be analogous to the claimed invention because both are in the same endeavor of techniques to coordinate CSI reports and matrices sizing.
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Ren with Yu to create the apparatus, wherein an observation window associated with the CSI report has a length equal to a time length for the codebook.
The motivation to combine both references would come from the need to restrict the overhead while still allowing the UE to dynamically adapt the precoder to exact radio conditions.
Regarding claim 12, Ren fails to disclose the apparatus, wherein an observation window associated with the CSI report has a length shorter than a time length for the codebook.

Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Ren in view of Fu et al (US20200037260A1) (hereinafter "Fu").
Regarding claim 17, Ren fails to disclose the apparatus, wherein CSI reference signals (CSI-RSs) for the CSI report each have a same time interval.
However, Fu discloses the apparatus, wherein CSI reference signals (CSI-RSs) for the CSI report each have a same time interval ([0261] receiving, by the UE, the CSI-RS resource of the periodic CSI report; or, [0264] determining, by the UE, the CSI-RS resource, on which one set of periodic CSI reports is based, and receiving the corresponding CSI-RS. [0722] When a plurality of UE-specific CSI-RS resources are selected, a plurality of UE-specific CSI-RS resources can be selected in a way of consecutively selecting a plurality of CSI-RS resources in the frequency domain, selecting a plurality of CSI-RS resources at equal intervals in the frequency domain, consecutively selecting a plurality of UE-specific CSI-RS resources in the time domain, or selecting a plurality of CSI-RS resources at equal intervals in time domain, or a combination of two or more of the above ways.).

Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Ren in view of Hosseini et al (US20190320453A1) (hereinafter "Hosseini").
Regarding claim 18, Ren fails to disclose the apparatus, wherein CSI reference signals (CSI-RSs) for the CSI report include at least a first CSI-RS and a second CSI-RS, wherein the first CSI-RS has a different time interval than the second CSI-RS.
However, Hosseini discloses the apparatus, wherein CSI reference signals (CSI-RSs) for the CSI report include at least a first CSI-RS and a second CSI-RS, wherein the first CSI-RS has a different time interval than the second CSI-RS ([0109] To perform channel estimation for some downlink channels, a base station 105-a may transmit CSI-RSs (e.g., CSI-RS 210) to the UE 115-a. The UE 115-a may perform the channel estimation and generate a channel state information (CSI) report and transmit the CSI report to the base station 105-a. [0159] In some examples, allocating the CSI-RS REs to the UE may include allocating at least two CSI-RS REs of the set of CSI-RS REs to the port of the UE in different radio frequency spectrum bands of the TTI within the same resource block. In some examples, allocating the CSI-RS REs to the UE may include allocating at least two CSI-RS REs of the set of CSI-RS REs to the port of the UE in different symbols of the TTI.).
