Office Action

§102 §103
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 Arguments Claims 1-8,10-14,16-19 and 21 are pending. Applicant’s arguments, see page 8, filed 05/20/2026, with respect to 35 U.S.C. 101 have been fully considered and are persuasive. The 35 U.S.C. 101 rejection of claim 14 has been withdrawn. Applicant's arguments filed 05/20/2026 against the prior art rejections have been fully considered but they are not persuasive. Applicant’s arguments against the independent claims and dependent claims, are basically about the limitation: the content header and the control information substructures are jointly encoded. Looking at the specification of the current application, the jointly encoded is described in page 5, line 165. PNG media_image1.png 263 716 media_image1.png Greyscale Clearly, this jointly encoded feature is simply CRC. This is very common before the effective filing date of current application. It appears that “jointly” simply means 1 CRC is used for the entire packet including the header and other control information. “Jointly” does not mean any more than that. Hwang on the other hand, teaches CRC in Fig. 6E. For the foregoing reasons, Applicant’s arguments are not persuasive. Response to Amendment Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-8, 11-12, 14 and 16-19 are rejected under 35 U.S.C. 102(a)1 as being anticipated by HWANG et al. (US20190335210A1), hereinafter HWANG.

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 10, 13 and 21 are rejected under 35 U.S.C. 103 as being unpatentable over HWANG et al. (US20190335210A1), hereinafter HWANG, in view of Parkvall et al. (US20170331670A1), hereinafter PARKVALL. Regarding claim 10, although HWANG teaches all the limitations with respect to claim 1 above, HWANG does not describe wherein the signaling structure comprises one of both: one or more substructures subject to an acknowledgement information process; and one or more substructures not subject to an acknowledgement information process. PARKVALL in the same field of endeavor teaches wherein the signaling structure comprises one of both: one or more substructures subject to an acknowledgement information process; and one or more substructures not subject to an acknowledgement information process. (PARKVALL, paragraph 1844, teach UE decision and acknowledgement via determining acknowledgement or rejection of resources.) Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine the teachings of PARKVALL with the teachings of HWANG to configure the signaling structure as one or more substructures subject to an acknowledgement information process, and one or more substructures not subject to an acknowledgement information process. The motivation would be to fast change resource share among each links to adapt to diverse link quality variations for links with the same frequency band (PARKVALL, paragraph 1844). Regarding claim 13, although HWANG teaches all the limitations with respect to claim 1 above, HWANG does not describe wherein the signaling structure comprises one or both of: at least one control information substructure comprising acknowledgement information pertaining to first transmission of subject transmission; and at least one control information substructure comprising acknowledgement information pertaining to re-transmitted subject transmission. PARKVALL in the same field of endeavor teaches wherein the signaling structure comprises one or both of: at least one control information substructure comprising acknowledgement information pertaining to first transmission of subject transmission; and at least one control information substructure comprising acknowledgement information pertaining to re-transmitted subject transmission. (PARKVALL, paragraph 1844, teach acknowledgement information pertaining to specified transmission of subject transmission.) Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine the teachings of PARKVALL with the teachings of HWANG to configure the signaling structure comprises one or both of at least one control information substructure comprising acknowledgement information pertaining to first transmission of subject transmission; and at least one control information substructure comprising acknowledgement information pertaining to re-transmitted subject transmission. The motivation would be to fast change resource share among each links to adapt to diverse link quality variations for links with the same frequency band (PARKVALL, paragraph 1844). Regarding claim 21, although HWANG teaches all the limitations with respect to claim 3 above, HWANG does not describe wherein the signaling structure comprises one of both: one or more substructures subject to an acknowledgement information process; and one or more substructures not subject to an acknowledgement information process. PARKVALL in the same field of endeavor teaches wherein the signaling structure comprises one of both: one or more substructures subject to an acknowledgement information process; and one or more substructures not subject to an acknowledgement information process. (PARKVALL, paragraph 1844, teach UE decision and acknowledgement via determining acknowledgement or rejection of resources.) Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine the teachings of PARKVALL with the teachings of HWANG to configure the signaling structure as one or more substructures subject to an acknowledgement information process, and one or more substructures not subject to an acknowledgement information process. The motivation would be to fast change resource share among each links to adapt to diverse link quality variations for links with the same frequency band (PARKVALL, paragraph 1844).
