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.
Claim(s) 11 and 24 is/are rejected under 35 U.S.C. 103 as being unpatentable over Liao in view of Kazmi et al. (US 2025/0159706) (“Kazmi”).
For claim 11 and 24; Liao discloses the subject matter in claim 1 as described above in the office action. Liao discloses: in accordance with a first spatial filter, transmission via a first subband of a first subband group (paragraph 6, 31, 35: aggregate distributed spectrum blocks within a frequency range (e.g., 200 MHz) by single carrier operation and facilitate UE to filter out the transmission of unknown RAT between any two of the distributed spectrum blocks…Each UE-specific BWP configuration can be either a single-cluster BWP or a multi-cluster BWP. In addition to UE-specific BWP configuration, the UE also receives CORESET configurations, each of which is associated to a DL BWP. When a CORESET is associated with a DL BWP, the frequency-domain location of the CORESET shall be within the DL BWP no matter it's a single-cluster BWP or a multi-cluster BWP.) in accordance with the first spatial filter, transmission via a second subband of the first subband group (paragraph 6, 31, 35: aggregate distributed spectrum blocks within a frequency range (e.g., 200 MHz) by single carrier operation and facilitate UE to filter out the transmission of unknown RAT between any two of the distributed spectrum blocks…Each UE-specific BWP configuration can be either a single-cluster BWP or a multi-cluster BWP. In addition to UE-specific BWP configuration, the UE also receives CORESET configurations, each of which is associated to a DL BWP. When a CORESET is associated with a DL BWP, the frequency-domain location of the CORESET shall be within the DL BWP no matter it's a single-cluster BWP or a multi-cluster BWP.).
Liao does not expressly disclose, but Kazmi from similar fields of endeavor teaches: receive, at a first transmit power (paragraph 16: the first downlink BWP and the second downlink BWP may be determined to be similar to each other when at least one of following conditions is satisfied:… a difference between transmission powers of the first RS and the second RS is within a predetermined threshold power; the difference between transmission powers of the first RS and the second RS is known to the terminal device) and a first reference signal via a first subband of a first subband group (paragraph 14: a bandwidth of the first downlink BWP may contain a first reference signal (RS), and a bandwidth of the second downlink BWP may contain a second RS); and receive, at a second transmit power (paragraph 16: the first downlink BWP and the second downlink BWP may be determined to be similar to each other when at least one of following conditions is satisfied:… a difference between transmission powers of the first RS and the second RS is within a predetermined threshold power; the difference between transmission powers of the first RS and the second RS is known to the terminal device) and a second reference signal via a second subband of the first subband group (paragraph 14: a bandwidth of the first downlink BWP may contain a first reference signal (RS), and a bandwidth of the second downlink BWP may contain a second RS), wherein a difference between the second transmit power and the first transmit power satisfies a threshold (paragraph 16: the first downlink BWP and the second downlink BWP may be determined to be similar to each other when at least one of following conditions is satisfied:… a difference between transmission powers of the first RS and the second RS is within a predetermined threshold power). Thus it would have been obvious to the person of ordinary skill in the art at the time of the invention to implement the similarity check as described by Kazmi in the distributed spectrum integration as described by Liao. The motivation is to improve compatibility of grouped clusters under the single carrier bwp.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Selvanesan et al. (US 2024/0406985); Selvanesan discloses CA in NR in accordance with embodiments allows to aggregate carriers in different BWPs, and thus, frequency bands with different numerologies can be aggregated. This has implications on timings and data rates if numerologies differ between the aggregated carriers.
