The AP CSI report may indicate L1-RSRP/SINR measurements of K CMRs”; ¶0116, “The UE may be further configured with the AP CSI report associated with the P/SP CSI report, whose report quantity includes at least L1-RSRP/SINR measurements of K CMRs, which may be different from the CMR IDs in a most recently reported P/SP CSI report. The UE may be dynamically triggered by the network node to report the AP CSI report”; ¶0132, “the UE may perform a CMR-common L1-RSRP/SINR quantization and reporting, to the network node, for multiple CMRs.

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.
Claims 3, 10-11 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over LI et al. (US 2025/0167852 A1), in view of Karjalainen et al. (US 2020/0336194 A1).
As to claims 3 and 10-11, LI does not specifically disclose transmit, to the user equipment, a reference offset parameter associated with the selected set of quantization levels, wherein the reference offset parameter is for controlling the at least one characteristic of the quantization of the at least one channel state information quantity; transmit, to the network entity, a recommended value for the at least one quantization parameter or for at least one reference offset parameter.
However, Karjalainen discloses transmit, to the user equipment, a reference offset parameter associated with the selected set of quantization levels, wherein the reference offset parameter is for controlling the at least one characteristic of the quantization of the at least one channel state information quantity; and transmit, to the network entity, a recommended value for the at least one quantization parameter or for at least one reference offset parameter (¶0062, “determining a quantized power offset for each RSRP value with respect to the reference power/RSRP value. For example, two bits may be used to indicate a power offset of four possible power offsets (0, 1, 2 and 3), with respect to the reference power/RSRP value”; ¶0063-¶0067; ¶0070, “element 1 includes a reference (e.g., maximum) RSRP of −54 dBm, and then the power offset values of 3, 0, 1, 2, 3, which correspond (based on element 2) to: SSB-20, CRI-7, CRI-9, CRI-5, CRI-2”; ¶0076, “a 2-bit power offset value (e.g., 0, 1, 2, 3) is assigned to each of the RSRP values of the SSB and CSI-RS resources for resource pair 1, to indicate the measured power/RSRP of each resource with respect to a reference RSRP, for example. For joint beam reporting, the network has configured the number of quantization bits, n=2, for this example. As a result of this, the following quantization RSRP levels are obtained: −54, −62.66, −71.33 and −80 dBm”; ¶0091, “The amount of quantization levels is defined as: Q=2n where n is the number of bits for quantization levels leading to Q−1 different power steps”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the system of LI to include transmit, to the user equipment, a reference offset parameter associated with the selected set of quantization levels, wherein the reference offset parameter is for controlling the at least one characteristic of the quantization of the at least one channel state information quantity; transmit, to the network entity, a recommended value for the at least one quantization parameter or for at least one reference offset parameter, as taught by Karjalainen because it would optimize the quantization scale for current channel conditions (Karjalainen; ¶0062-¶0067; ¶0076; ¶0091).
As to claims 19-20, they are rejected for the same reasons set forth in claims 10-11 above, respectively.
Claims 7-9 and 16-18 are rejected under 35 U.S.C. 103 as being unpatentable over LI et al. (US 2025/0167852 A1), in view of Wang et al. (US 2023/0006793 A1).
As to claims 7, 9, 16 and 18, LI does not specifically disclose determine a time domain correlation between two or more channel state information reference signals; quantize an amplitude of at least one time correlation function coefficient obtained from the two or more channel state information reference signals using the determined set of quantization levels.
However, Wang discloses determine a time domain correlation between two or more channel state information reference signals; and quantize an amplitude of at least one time correlation function coefficient obtained from the two or more channel state information reference signals using the determined set of quantization levels (Fig. 5; Figs. 8-9; ¶0007, “determines a first CSI reference slot for measurement and a second CSI reference slot for computation from the CSI-RS configuration information. The second CSI reference slot occurs after the first CSI reference slot in time domain. The UE measures CSI reference signals (CSI-RS) of a downlink channel that is received before the first CSI reference slot for measurements”; ¶0027, “UE is configured to compute CSI based on one single occasion or multiple occasions of CSI-RS over configured CSI reference resource, e.g., a group of downlink frequency domain and time domain resource blocks…In the time domain, the CSI reference resource is defined by a single downlink slot or special subframe to which the derived CQI value relates”; ¶0032; ¶0033, “UE is configured to compute CSI based on multiple occasions of CSI-RS measured no later than SLOT (n-nCSI_ref), the UE can consider time domain correlation of the multiple occasions of CSI-RS to predict the CSI in SLOT (n+K). In addition, the UE is configured with a CSI computation period (e.g., across multiple slots) with a whole period and multiple non-overlapping subperiods, which can exploit time-domain correlation”; ¶0034; ¶0040-¶0041; ¶0088, “select L-strongest resources has following options for selecting a strongest resource pair out of L pairs: There may be multiple (e.g., 3) ways to select the best/strongest resource pair to report: 1) SSB-only: UE selects L-strongest (L≤K) resource pairs in terms of measured SSB L1-RSRP values and their corresponding resource indicators/indices”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the system of LI to include determine a time domain correlation between two or more channel state information reference signals; quantize an amplitude of at least one time correlation function coefficient obtained from the two or more channel state information reference signals using the determined set of quantization levels, as taught by Wang because it would reduce feedback overhead and improve estimation accuracy (Wang; ¶0033-¶0034).
As to claims 8 and 17, LI discloses wherein determining the at least one quantized channel state information quantity further comprises the at least one memory stores instructions that, when executed by the at least one processor, cause the apparatus to: determine a set of quantization levels based, at least partially, on at least one of the at least one quantization parameter (¶0102, “measured by the UE during a specified time period), seven bits may be used to report a corresponding RSRP (in the range of [−140, −44] dBm with a 1 dBm step size). For remaining SSBRI(s) and/or CRI(s), four bits may be used to report a differential RSRP in the range of [0, −30] dB with a 2 dB step size and a reference to the L1-RSRP of the strongest SSBRI and/or CRI”; ¶0135, “one or more quantization metrics may be predefined, such as MMSE applied for a past time domain window length, MMSE applied only for a current reporting instance, and/or one or more choices of quantity of bits, dynamic range, and step size to quantize the CMR-common L1-RSRP/SINR measurement”).
