DETAILED ACTION
The following is a final office action in response to applicant’s remarks/arguments 10/22/2025 for
response of the office action mailed on 8/15/2025. Claims 1, 4, 6, 8, 11, 14, 16, and 18 have been amended. Claims 5 and 15 have been canceled. Claims 1-4, 6-14, and 16-20 remain pending in the application.
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor
to file provisions of the AIA .
Response to Remarks/Arguments
Applicant’s remarks/arguments (page 10-12), filed on 10/22/2025, with respect to claim 1 have been
fully considered but are not persuasive.
Regarding remarks in page 11 for independent claim 1, applicant asserts that Hwang fails to teach or disclose interleaving the modulated first information based on the quantity of transport layers and a quantity of bits comprised in the first information. Mere mention of a MAC layer in Hwang as part of background recitations is not sufficient to teach a person skilled in the art that a MAC layer should be used as a basis of interleaving, let alone a particular quantity of layers, MAC, transport, or otherwise.
Examiner respectfully disagrees with the applicant. HWANG et al. (US 2022/0158760 Al) discloses (“the number of the plurality of first bits may be determined based on at least one of a number of layers for a transport block related to the first encoded code block, a number of bits per a modulation symbol, a number of code blocks included in the transport block, or a total number of coded bits available for the transport block, Hwang: [0219]”, “UE performs interleaving for some bits of an encoded code block., Hwang: Fig. 13, Fig. 17, [0165]-[0168]”, “MAC layer provides a function of mapping multiple logical channels to multiple transport channels, Hwang: [0071]”, and “Referring to FIG. 26, a signal processing circuit 1000 may include scramblers 1010, modulators 1020, a layer mapper 1030, a precoder 1040, resource mappers 1050, and signal generators 1060. Complex modulation symbol sequences may be mapped to one or more transport layers by the layer mapper 1030. Modulation symbols of each transport layer may be mapped (precoded) to corresponding antenna port(s) by the precoder 1040, Hwang: Fig. 16, [0266]-[0268]”).
The newly added limitations in the amendment and the new ground of rejections using a newly introduced reference (ZHANG et al.) is applied in the current rejection.
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 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.
