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.
Claims 4-7, 16, and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Pezeshki et al. (US 2021/0195462) in view of Gutman et al. (US 2021/0050981).
Regarding Claim 4, Pezeshki teaches the invention of Claim 1, but does not teach wherein determining the compression method comprises: determining a set of compression parameter values based on at least one of the following: a mapping between the channel quality information and at least one compression parameter value in the set of compression parameter values, or a mapping among at least two compression parameter values in the set of compression parameter values.
In the same field of endeavor, Gutman teaches wherein determining the compression method comprises: determining a set of compression parameter values based on at least one of the following: a mapping between the channel quality information and at least one compression parameter value in the set of compression parameter values, or a mapping among at least two compression parameter values in the set of compression parameter values (Par. [0064] “FIG. 2 illustrates an example of a table 200 showing an example mapping of subband differential CQI values to different offset values. As illustrated in FIG. 2, to reduce overhead, the number of offset levels configured to be indicated may be low (e.g., four offset levels)” and Par. [0076] “In the above examples, UE 115-a may select an encoding scheme for reporting CQI for a set of subbands based on a frequency correlation between the set of subbands”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Gutman’s subband mapping with Pezeshki’s compression method to improve the efficiency in reporting channel state feedback.
Regarding Claim 5, Pezeshki in view of Gutman teaches the invention of Claim 4, with Gutman further teaching wherein the set of compression parameter values comprises at least one of the following: a compression ratio, the number of quantization bits, or the number of compressed bits (Par. [0076] “In the above examples, UE 115-a may select an encoding scheme for reporting CQI for a set of subbands based on a frequency correlation between the set of subbands. UE 115-a may then report different CQI indices using different numbers of bits, where the indication of the CQI index for one subband is an offset of the CQI index indicated for a previous, adjacent subband”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Gutman’s different number of compression bits with Pezeshki’s compression method to improve the efficiency in reporting channel state feedback.
Regarding Claim 6, Pezeshki in view of Gutman teaches the invention of Claim 4, with Pezeshki further teaching transmitting, to the network device, at least one compression parameter in the set of compression parameters (Par. [0070] “As illustrated, the UE may transmit the codeword 612 (e.g., along with the one or more parameter multiplexed with the codeword) to the BS 110”).

In the same field of endeavor, Gutman teaches wherein determining the compression method comprises: in accordance with a determination that channel quality indicated by the channel quality information is below first threshold quality, determining a first predetermined compression method as the compression method; (Par. [0076] “In the above examples, UE 115-a may select an encoding scheme for reporting CQI for a set of subbands based on a frequency correlation between the set of subbands”),
in accordance with a determination that channel quality indicated by the channel quality information is below second threshold quality, determining that no compression is applied;
or in accordance with a determination that channel quality indicated by the channel quality information is above third threshold quality, determining a second predetermined compression method as the compression method (Fig. 5, Par. [0075] “UE 115-a may select an encoding scheme of the configured encoding schemes (e.g., the three encoding schemes described with reference to FIG. 5) based on determining which of the encoding schemes most accurately represents the frequency correlation between identified CQI indices (e.g., which probabilities for reporting CQI indices are closest to the actual CQI probabilities determined based on the correlation between CQI indices)”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Gutman’s encoding schemes based on channel quality information with Pezeshki’s compression method to improve the efficiency in reporting channel state feedback.
Regarding Claim 16, Pezeshki teaches the invention of Claim 13, but does not teach wherein determining the compression method comprises: determining a set of compression parameter values based on at least one of the following: a mapping between the channel quality information and at least one compression parameter in the set of compression parameter values, or a mapping among at least two compression parameter values in the set of compression parameter values.
In the same field of endeavor, Gutman teaches wherein determining the compression method comprises: determining a set of compression parameter values based on at least one of the following: a mapping between the channel quality information and at least one compression parameter value in the set of compression parameter values, or a mapping among at least two compression parameter values in the set of compression parameter values (Par. [0064] “FIG. 2 illustrates an example of a table 200 showing an example mapping of subband differential CQI values to different offset values. As illustrated in FIG. 2, to reduce overhead, the number of offset levels configured to be indicated may be low (e.g., four offset levels)” and Par. [0076] “In the above examples, UE 115-a may select an encoding scheme for reporting CQI for a set of subbands based on a frequency correlation between the set of subbands”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Gutman’s subband mapping with Pezeshki’s compression method to improve the efficiency in reporting channel state feedback.
Regarding Claim 19, Pezeshki teaches the invention of Claim 13, but does not teach wherein determining the compression method comprises: in accordance with a determination that channel quality indicated by the channel quality information is below first threshold quality, determining a first predetermined compression method as the compression method; in accordance with a determination that channel quality indicated by the channel quality information is below second threshold quality, determining that no compression is applied; or in accordance with a determination that channel quality indicated by the channel quality information is above third threshold quality, determining a second predetermined compression method as the compression method.
In the same field of endeavor, Gutman teaches wherein determining the compression method comprises: in accordance with a determination that channel quality indicated by the channel quality information is below first threshold quality, determining a first predetermined compression method as the compression method; (Par. [0076] “In the above examples, UE 115-a may select an encoding scheme for reporting CQI for a set of subbands based on a frequency correlation between the set of subbands”),
in accordance with a determination that channel quality indicated by the channel quality information is below second threshold quality, determining that no compression is applied;
or in accordance with a determination that channel quality indicated by the channel quality information is above third threshold quality, determining a second predetermined compression method as the compression method (Fig. 5, Par. [0075] “UE 115-a may select an encoding scheme of the configured encoding schemes (e.g., the three encoding schemes described with reference to FIG. 5) based on determining which of the encoding schemes most accurately represents the frequency correlation between identified CQI indices (e.g., which probabilities for reporting CQI indices are closest to the actual CQI probabilities determined based on the correlation between CQI indices)”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Gutman’s encoding schemes based on channel quality information with Pezeshki’s compression method to improve the efficiency in reporting channel state feedback.
Claims 8-9 are rejected under 35 U.S.C. 103 as being unpatentable over Pezeshki et al. (US 2021/0195462) in view of Yang et al. (US 2025/0253901).
Regarding Claim 8, Pezeshki teaches the invention of Claim 1, further teaching wherein compressing the channel state information comprises: transmitting, to the network device, an indication of the compression method; (Par. [0070] “As illustrated, the UE may transmit the codeword 612 (e.g., along with the one or more parameter multiplexed with the codeword) to the BS 110”).
Pezeshki, however, does not explicitly teach starting the compressing of the channel state information at a predetermined timing after the transmission of the indication or a reception of a confirmation for the indication.
In the same field of endeavor, Yang teaches starting the compressing of the channel state information at a predetermined timing after the transmission of the indication or a reception of a confirmation for the indication (Par. [0141] In step 803, in response to that the scenario information satisfies a usage condition of a compression algorithm in the algorithm list, the compression algorithm is determined to be the target compression algorithm” and Par. [0147] “Optionally, the terminal device may determine a compression algorithm to be the target compression algorithm in response to that the time information of the terminal device in the scenario information satisfies a time range in the usage condition of the compression algorithm in the algorithm list” and Par. [0151] “In step 804, the CSI is compressed using the target compression algorithm to obtain compressed CSI”)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Yang’s time range with Pezeshki’s compression method to overcome attenuation and loss during performance.
Regarding Claim 9, Pezeshki teaches the invention of Claim 1, further teaching wherein compressing the channel state information comprises: receiving, from the network device, an indication of the compression method; (Par. [0068] “As illustrated, the UE 120 may receive a configuration 602 (e.g., associated with configuration 510) for compression of one or more measurements”).
Pezeshki, however, does not explicitly teach starting the compressing of the channel state information at a predetermined timing after the reception of the indication or a transmission of an acknowledgement for the indication.
In the same field of endeavor, Yang teaches starting the compressing of the channel state information at a predetermined timing after the reception of the indication or a transmission of an acknowledgement for the indication (Par.

[0151] “In step 804, the CSI is compressed using the target compression algorithm to obtain compressed CSI”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Yang’s time range with Pezeshki’s compression method to overcome attenuation and loss during performance.
Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Pezeshki et al. (US 2021/0195462) in view of Park et al. (US 2021/0409991).

[0070] “As illustrated, the UE may transmit the codeword 612 (e.g., along with the one or more parameter multiplexed with the codeword) to the BS 110”).
Pezeshki, however, does not explicitly teach receiving, from the network device, a configuration updated based on the compression method, the configuration comprising at least one of the following: a time-domain configuration, a frequency-domain configuration, an antenna-port-domain configuration, a beam-domain configuration, a resource for the transmission of the compressed channel state information, or a format for the transmission of the compressed channel state information.
In the same field of endeavor, Park teaches receiving, from the network device, a configuration updated based on the compression method, the configuration comprising at least one of the following: a time-domain configuration, a frequency-domain configuration, an antenna-port-domain configuration, a beam-domain configuration, a resource for the transmission of the compressed channel state information, or a format for the transmission of the compressed channel state information (Par. [0337] “In addition, regarding the CSI-RS, resource element (RE) mapping of CSI-RS resources of the CSI-RS is performed in time and frequency domains by higher layer parameter CSI-RS -ResourceMapping”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Park’s time domain and frequency domain updates with Pezeshki’s compression method to minimize the degradation of performance when reporting channel state information.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Sun et al. (WO 2022/067862) (found in IDS) discloses “At 415, the UE 110 performs the CSI measurements based on the allocated CSI-RS resources. At 420, the UE 110 transmits the CSI report to the gNB 120a” (Par. [0036]).
Song et al. (WO 2021/142631) (found in IDS) discloses “In some embodiments, the terminal device may determine a mode of the compression and compress the CSI based on the mode. As described above in some embodiments, the mode of compression of the compressed CSI may be divided into a first compression mode that is ML friendly with a common codebook” (Par. [0073]).
Wang et al. (US 2024/0063868) discloses “Optionally, the CSI report is divided into part 1 and part 2. The CSI report includes the compressed channel information and/or the interference measurement result obtained by the terminal device under the intelligent CSI feedback scenario, such that the terminal device is able to report the CSI report including the compressed channel information and/or interference measurement result. As such, the technical solution of CSI supporting under the intelligent CSI feedback scenario can be achieved” (Par. [0041]).
