Regarding claims 1, 10 and 16, Park teaches a user equipment (UE) in a communication system, the UE (Para. [0693]-Park discloses BS/UE operation (e.g., Proposal 1/Proposal 1-1/Proposal 2/Proposal 2-1/Proposal 2-2/Proposal 2-3/FIG. 24) may be processed by one or more processors (e.g., 102 and 202) of FIGS. 26 to 29 and the BS/UE operation (e.g., Proposal 1/Proposal 1-1/Proposal 2/Proposal 2-1/Proposal 2-2/Proposal 2-3/FIG. 24) may be stored in a memory (e.g., one or more memories (e.g., 104 and 204) of FIG. 26) in the form of an instruction/program (e.g., instruction and executable code) for driving at least one processor (e.g., 102 and 202) of FIGS. 26 to 29. Para.

When the PUSCH {Physical Uplink Shared Channel} is scheduled by DCI format 0_1, the UE determines a PUSCH {Physical Uplink Shared Channel} transmission precoder based on the SRI, the Transmit Precoding Matrix Indicator (TPMI), and the transmission rank from the DCI as given by the SRS resource indicator field and the Precoding information and number of layers field. The TPMI is used for indicating a precoder to be applied over the antenna port and when multiple SRS resources are configured, the TPMI corresponds to the SRS resource selected by the SRI),
the UL transmission corresponds to a codebook-based transmission (Tables 9 and 15, Para.

On the contrary, when higher layer parameter ‘txConfig’ is set to ‘nonCodebook’, the UE is configured to the non-codebook based transmission. When higher layer parameter ‘txConfig’ is not configured, the UE does not predict that the PUSCH is scheduled by DCI format 0_1. When the PUSCH is scheduled by DCI format 0_0, the PUSCH transmission is based on a single antenna port), and
the UL transmission is based on N antenna ports (Para.

As such, based on constituting the specific TPMI group, the difference of the phase value applied to antenna ports respectively included in antenna port pairs ((i) antenna ports 0 and 2 and (ii) antenna ports 1 and 3) may be diversified. Para. [0455-0457]-Park discloses UE receives the PDSCH, a precoding granularity P′ may be assumed as a consecutive resource block in the frequency domain. Here, P′ may correspond to one value of {2, 4, and wideband} ... when P′ is determined as any one of {2 and 4}, a Precoding Resource Block Group (PRG) is split into P′ consecutive PRBs.

[0475]-Park discloses modulated symbols of each transport layer may be mapped to a corresponding antenna port(s) by the precoder. In this case, mapping the modulated symbols of each transport layer to the antenna port(s) corresponds to precoding. Para. [0714]-Park discloses modulated symbols of each transport layer may be mapped to a corresponding antenna port(s) by the precoder 1040 (precoding). Output z of the precoder 1040 may be obtained by multiplying output y of the layer mapper 1030 by precoding matrix W of N*M. Here, N represents the number of antenna ports and M represents the number of transport layers. Para. [0442-0468]-Park discloses UE receives, from the BS, DCI for downlink scheduling (i.e., including scheduling information of the PUSCH) ... a PUSCH transmission precoder based on the SRI, the Transmit Precoding Matrix Indicator (TPMI), and the transmission rank from the DCI as given by the SRS resource indicator field and the Precoding information and number of layers field.

Response to Arguments
Applicant's Arguments/Remarks, filed on 02/20/2026, with respect to the 35 USC § 102 rejection of claims 1-3, 10-12 and 16-18 have been fully considered. Applicant’s arguments are not persuasive.
In the remarks, on pages 12 and 13, Lines [18-19 and 2-8 respectively], Applicant argues that, “…Nowhere do these cited portions of Park teach "a first indicator I indicating G groups of antenna ports, g1, ..., gG"” and “…Park contains no disclosure of any signaling that enumerates "G groups of antenna ports, g1, ..., gG" ... The relevant descriptions do not disclose a parameter that constitutes "a first indicator I indicating G groups of antenna ports, g1, ... , gG, where group gi includes ni antenna ports selected from ... N antenna ports."” respectively.
However, Park teaches receive, via higher layer signaling, a first indicator I indicating G groups of antenna ports, gi,..., gG (Para. [0299]-Park discloses the UE receives, from the BS, RRC signaling (e.g., SRS-Config IE) including a (higher layer parameter) usage parameter configured as ‘beam management’ (S1510). Para. [0442-0468]-Park discloses UE receives, from the BS, DCI for downlink scheduling (i.e., including scheduling information of the PUSCH) on the PDCCH (S2002). Para. [0442-0468]-Park discloses UE receives, from the BS, DCI for downlink scheduling (i.e., including scheduling information of the PUSCH) ... a PUSCH transmission precoder based on the SRI, the Transmit Precoding Matrix Indicator (TPMI), and the transmission rank from the DCI as given by the SRS resource indicator field and the Precoding information and number of layers field. The TPMI is used for indicating a precoder to be applied over the antenna port and when multiple SRS resources are configured, the TPMI corresponds to the SRS resource selected by the SRI. Para. [0475]-Park discloses modulated symbols of each transport layer may be mapped to a corresponding antenna port(s) by the precoder. Para. [0714]-Park discloses precoding matrix W of N*M. Here, N represents the number of antenna ports and M represents the number of transport layers. Para. [0303]-Park discloses a transmission precoder is selected from a UL codebook having the same number of antenna ports as indicated by a higher layer parameter ‘nrofSRS-Ports’. Table 5, Para. [0183]-Park dscloses a parameter reference signal indicates reference antenna port(s) serving as a QCL source for target antenna port(s). Abstract-Park discloses receiving Downlink Control Indicators (DCI) including first to n-th field values; and transmitting identical uplink data to the plurality of TRPs by using the same number of antenna ports ... In another example, a TCI state ID may be indicated by DCI to indicate QCL reference information for PDSCH DMRS antenna port(s)), where group g, includes n antenna ports selected from the N antenna ports (Para. [0605-0709]-Park discloses one or more antennas may be a plurality of physical antennas or a plurality of logical antennas (e.g., antenna ports). Para. [0247]-Park discloses UE receives a plurality of DL antenna ports having a QCL Type D relationship. Table 36, Para. [0605-0606]-Park discloses TPMI group includes TPMIs 12 to 15 … the specific TPMI group may be configured to include TPMIs 12, 17, 22, and 27. As such, based on constituting the specific TPMI group, the difference of the phase value applied to antenna ports respectively included in antenna port pairs ((i) antenna ports 0 and 2 and (ii) antenna ports 1 and 3) may be diversified. Para. [0455-0457]-Park discloses UE receives the PDSCH, a precoding granularity P′ may be assumed as a consecutive resource block in the frequency domain. Here, P′ may correspond to one value of {2, 4, and wideband} ... when P′ is determined as any one of {2 and 4}, a Precoding Resource Block Group (PRG) is split into P′ consecutive PRBs. The number of actually consecutive PRBs in each PRG may be one or more. The UE may assume that the same precoding is applied to consecutive downlink PRBs in the PRG. Para. [0009]-Park discloses codebook subset includes at least one specific precoding matrix applying different phase values to antenna ports included in all or some of the some antenna ports).
In the remarks, on page 15, Lines [9-10], Applicant argues that, “…Park does not teach or suggest "an uplink (UL) transmission ... [that] corresponds to a codebook-based transmission, and ... is based on N antenna ports," "wherein ... N is 8.".”
However, Park teaches to: receive information about an uplink (UL) transmission (Para.

The TPMI is used for indicating a precoder to be applied over the antenna port and when multiple SRS resources are configured, the TPMI corresponds to the SRS resource selected by the SRI), wherein the UL transmission corresponds to a codebook-based transmission (Tables 9 and 15, Para. [0467]-Park discloses When higher layer parameter ‘txConfig’ is set to ‘codebook’, the UE is configured to the codebook based transmission. On the contrary, when higher layer parameter ‘txConfig’ is set to ‘nonCodebook’, the UE is configured to the non-codebook based transmission. When higher layer parameter ‘txConfig’ is not configured, the UE does not predict that the PUSCH is scheduled by DCI format 0_1. When the PUSCH is scheduled by DCI format 0_0, the PUSCH transmission is based on a single antenna port), and … transmit the UL transmission based on the identified G groups, the precoding matrix, and the number of layers (Para. [0442-0468]-Park discloses UE receives, from the BS, DCI for downlink scheduling (i.e., including scheduling information of the PUSCH) on the PDCCH (S2002) … the PUSCH may be scheduled by DCI format 0_0 or DCI format 0_1, or semi-statically.

Para. [0513]-Park discloses the size of the field ‘precoding information and number of layers’ may be differently configured based on higher layer parameters and the number of antenna ports used for the uplink transmission by the UE. The higher layer parameters may include ‘txConfig’, ‘transform precoder’, ‘maxRank’, and ‘codebooksubset’. Para. [0529]-Park discloses the UE may scale a linear value with a ratio of the number of antenna ports having non-zero PUSCH transmission power to the maximum SRS port number supported in one SRS resource by the UE. The UE equally splits the power across the antenna port in which the UE transmits the PUSCH with non-zero power. Para. [0714]-Park discloses a complex modulated symbol sequence may be mapped to one or more transport layers by the layer mapper 1030. Modulated symbols of each transport layer may be mapped to a corresponding antenna port(s) by the precoder 1040 (precoding).
