Office Action

§103
DETAILED ACTION 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 . 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. Claim(s) 1-30 are rejected under 35 U.S.C. 103 as being unpatentable over Lu et al. (US 2025/0184975 A1), hereinafter referred to as D1, in view of Moderator (CATT), Summary #3 of Subband Non-Overlapping Full Duplex, R1-230xxxx, 3GPP TSG RAN WG1 #112bis-e, April 17, 2023, pp. 1-158, hereinafter referred to as D2. Regarding claims 1, 10, 19, and 28, D1 discloses resource configuration method, communication apparatus, and system, which comprises: one or more memories storing processor-executable code; and one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to: transmit a UE capability message indicating support for downlink transmission scheduling in one or more downlink subbands of a subband full duplex slot (Referring to Figure 5, S530: The terminal device, comprising memory and processors, see Figure 8, sends second signaling to the network device, where the second signaling indicates that the terminal device supports the SBFD, subband full duplex, function (capability message indicating support for downlink transmission scheduling in one or more downlink subbands of a subband full duplex slot). Correspondingly, the network device receives the second signaling from the terminal device and performs uplink and downlink communications. See paragraphs 0153 and 0154.) .D1 does not disclose the downlink transmission scheduling associated with wideband precoding across contiguous frequency resources within a bandwidth part of the UE, across non-contiguous frequency resources within the bandwidth part, or both; receive, based at least in part on the UE capability message, a grant scheduling a downlink transmission in the one or more downlink subbands; and receive the downlink transmission within the one or more downlink subbands according to the grant. D2 teaches downlink transmission scheduling associated with wideband precoding for contiguous and non-contiguous frequency resources as taught by D2, See Section 3.1.2.1.2 PRG, wideband precoder in case of non-contiguous DL subbands and non-contiguous frequency resources across two DL subbands can be scheduled/configured for the PDSCH. D2 teaches receiving a grant scheduling a downlink transmission in the one or more subbands and receiving the downlink transmission within the subband per the grant, which is interpreted as dynamic SBFD communication as taught by D2 discussing dynamic SBFD operation utilizing dynamic grant based scheduling according to transmission direction, downlink or uplink, for the subbands; thereby, comprising downlink communication in the system. See Proposal 1-8b: Proposed Agreement, Options 1-3 and Comments, Samsung. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to implement the dynamic SBFD of D2 in the system of D1. One of ordinary skill in the art before the effective filing date of the invention would have been motivated to do so to comply with well-known standards and improve system compatibility. Regarding claims 2, 11, 20, and 29, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: indicate, via the UE capability message, a first support for a first wideband precoding for a first set of contiguous frequency resources in a first subband of the one or more downlink subbands and a second support for a second wideband precoding for a second set of contiguous frequency resources in a second subband of the one or more downlink subbands, wherein the first wideband precoding is different from the second wideband precoding (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claims 3, 12, 21, and 30, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: assume a same transmission configuration index (TCI) state, a same quasi-collocation (QCL) relationship, or both, per set of contiguous frequency resources (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claims 4, 13, and 22, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: indicate, via the UE capability message, a support for a common wideband precoding across two sets of contiguous frequency resources in at least two subbands within the bandwidth part (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claims 5, 14, and 23, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: assume a same transmission configuration index (TCI) state, a same quasi-collocation (QCL) relationship, or both, across the two sets of contiguous frequency resources (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claims 6, 15, and 24, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: indicate, via the UE capability message, a first support for a first wideband precoding for a first set of contiguous frequency resources in a first subband of the one or more downlink subbands and a second support for a second wideband precoding for a second set of contiguous frequency resources in a second subband of the one or more downlink subbands, wherein the first wideband precoding is a same precoding as the second wideband precoding (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claim 7, 16, and 25, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: assume a same transmission configuration index (TCI) state, a same quasi-collocation (QCL) relationship, or both, per set of contiguous frequency resources (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claims 8, 17, and 26, wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: indicate, via the UE capability message, a maximum number of sets of contiguous frequency resources for the wideband precoding supported by the UE (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Regarding claims 9, 18, and 27, wherein a default maximum number of sets is two sets (Note, the parent claim is listed in the alternative form transmit a capability message indicating support for downlink transmission scheduling . . . associated with . . . contiguous frequency resources . . . non-contiguous frequency resources . . . or both. The Examiner interprets the claim as a list in the alternative form and the parent claim is taught in light of D2’s non-contiguous frequency resources. The instant claim relates to the contiguous frequency resources recited in the parent claim and is taught in light of rejection of parent claim’s alternative form.) Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Yang et al. (US 2024/0224254 A1) - The apparatus may be a UE. The configuration specifies a bundle size N. Modulation symbols in N consecutive PRBs are precoded with a same precoder. The UE determines whether a precoding condition is true. The precoding condition is that modulation symbols in a first set of resources and a second set of resources are precoded with a same precoder. Haghighat et al. (US 2021/0092720 A1) - Included among these classes are methods for use in connection with dynamic precoding resource block group (PRG) configuration and with codebook based transmission configuration. Papasakellariou (US 2021/0091988 A1) - A method for a user equipment (UE) to receive physical downlink control channels (PDCCHs) is provided. A method for constructing a search space to reduce a number of channel estimations that the UE performs for decoding PDCCHs, relative to conventional search spaces, is also provided.
