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.
In 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.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
Claims 2 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Muruganathan, in view of Gao et al. (2025/0106865), Gao hereinafter.
Re. claims 2 and 17, Muruganathan teach claims 1 and 16.
Muruganathan further teaches receive downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH) , wherein: the DCI comprises a transmission configuration indicator (TCI) field (Fig. 8 - Fig. 12 & ¶0147 - When scheduling a PDSCH to a UE, the DCI contains a pointer to one active TCI); a TCI codepoint corresponding to the TCI field comprises a single TCI state (Fig. 8 - Fig. 12 & ¶0146 - Each configured TCI state contains parameters for the quasi co-location associations between source reference signals (CSI-RS or SS/PBCH) and target reference signals (e.g., PDSCH/PDCCH DMRS ports). TCI states are also used to convey QCL information for the reception of CSI-RS. Fig. 8 - Fig. 12 & ¶0149 - When a TCI state is used for both DL and UL, this TCI state may be referred to as joint TCI state or unified TCI state.); and
Yet, Muruganathan does not expressly teach the single TCI state indicates a quasi-co-location (QCL) relationship between a reference signal (RS) of demodulation reference signal (DMRS) corresponding to PDSCH and a CSI-RS of at least the selected subset of the plurality of CSI-RS port groups.
However, in the analogous art, Gao explicitly discloses the single TCI state indicates a quasi-co-location (QCL) relationship between a reference signal (RS) of demodulation reference signal (DMRS) corresponding to PDSCH and a CSI-RS of at least the selected subset of the plurality of CSI-RS port groups. (Fig. 1-3 & ¶0046 - a UE can be configured with a list of up to T TCI-State configurations within the higher layer parameter PDSCH-Config to decode PDSCH according to a detected PDCCH with DCI intended for the UE … Each TCI-State contains parameters for configuring a quasi co-location relationship between one or two downlink reference signals and the DMRS ports of the PDSCH, the DMRS port of PDCCH or the channel state information reference signal (CSI-RS) port(s) of a CSI-RS resource.Fig. 1-3 & ¶0124 - there may be a transmission configuration indication (TCI) field in DCI. A value of the TCI field may be referred to as a “TCI codepoint”. A TCI codepoint may indicate one or more TCI states. Each TCI state contains parameters for configuring a quasi co-location (QCL) relationship between one or two DL and/or UL reference signals and the DMRS ports of the PDSCH, ….. the CSI-RS ports of a CSI-RS resource. Fig. 1-3 & ¶0125 - there may be an application timing for beam indication or TCI state(s) indication. In some embodiments, the application timing may be the first slot or the first subslot that is at least Y symbols after the last symbol of acknowledge of the joint or separate DL/UL beam indication or TCI state indication. … the acknowledge of the joint or separate DL/UL beam indication may be the acknowledge of the PDSCH scheduled by the DCI, for example, when the DCI schedules the PDSCH. In some embodiments, the acknowledge of the joint or separate DL/UL beam indication may be the acknowledge of the DCI, for example, when the DCI doesn't schedule a PDSCH. Fig. 1-3 & ¶0127 - the terminal device 130 may receive or detect a DCI (for example, represented as “DCI_t”) in a PDCCH, and the DCI indicates a joint DL/UL TCI state or a separate DL/UL TCI state or a DL TCI state or a UL TCI state or a pair of DL/UL TCI states. … when a joint DL/UL TCI state is indicated in the DCI, the joint DL/UL TCI state may be applied to PDSCH and/or CORESET and/or PUSCH and/or PUCCH and/or uplink RS and/or downlink RS after the application timing or the first time threshold).
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Muruganathan’s invention of a system and a method for Channel State Information (CSI) reporting with angle and delay reciprocity in a wireless communication system to include Gao’s invention of a system and a method for supporting a unified Transmission Configuration Indication (TCI) framework for downlink and uplink beam indication in a wireless communication system, because it provides an efficient mechanism in facilitating more efficient (lower latency and overhead) downlink (DL) and uplink (UL) beam management, in turns, supporting common beam(s) for data and control information transmission/reception for both DL and UL, especially for operations, such as, intra-band carrier aggregation (CA) between a plurality of Base stations and a terminal operating in the wireless communication system.

Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Muruganathan, in view of Luo et al. (2025/0007667), Luo hereinafter.
Re. claim 9, Muruganathan teach claim 1.
Yet, Muruganathan does not expressly teach wherein the at least one processor is configured to cause the UE to configure a number of tracking reference signals (TRSs) of a plurality of TRS to be equivalent to a number of CSI-RS port groups of the plurality of CSI-RS port groups, wherein each TRS of the plurality of TRSs is associated with each CSI-RS port group of the plurality of CSI-RS port groups.
However, in the analogous art, Luo explicitly discloses wherein the at least one processor is configured to cause the UE to configure a number of tracking reference signals (TRSs) of a plurality of TRS to be equivalent to a number of CSI-RS port groups of the plurality of CSI-RS port groups , wherein each TRS of the plurality of TRSs is associated with each CSI-RS port group of the plurality of CSI-RS port groups (Fig. 3-10 & ¶0180 - trs-Info: indicating that antenna ports of all NZP-CSI-RSs in the CSI-RS resource set are the same, and are used for TRS for UE specific configuration.Fig. 3-10 & ¶0182 - If the trs-Info parameter is configured in the NZP CSI-RS resource set of UE, UE assumes that the antenna ports with the same port index for NZP CSI-RS resources configured in the NZP CSI-RS resource set are the same. Fig. 3-10 & ¶0356 - For configuring each CSI-RS/TRS resource set group independently by the first parameter set exclusive to the TRS resources, as shown in FIG. 9. In this case, the specific resource configuration information for a TRS is as follows. Fig. 3-10 & ¶0359 - When the base station can configure up to 6 TRS-Resource set groups, that is, the base station needs L1 signaling to indicate a maximum of 6 TRS-Resource set groups, then the TRS-Resource set group IDs need to be indicated by 3 bits. One TRS-Resource set group supports up to 7 CSI-RS resources which are indicated by 3 bits. ).
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Muruganathan’s invention of a system and a method for Channel State Information (CSI) reporting with angle and delay reciprocity in a wireless communication system to include Luo’s invention of a system and a method for resource configuration in a wireless communication system, because it provides an efficient mechanism in achieving energy saving and reducing system overhead when configuring parameter information of reference signals for a terminal in Idle/inactive mode operating in the wireless communication system.

Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Muruganathan, in view of Xi et al. (2025/0007586), Xi hereinafter.
Re. claim 11, Muruganathan teach claim 1.
Yet, Muruganathan does not expressly teach wherein the CSI report comprises an indicator of the selected subset of the plurality of CSI-RS port groups.
However, in the analogous art, Xi explicitly discloses wherein the CSI report comprises an indicator of the selected subset of the plurality of CSI-RS port groups. (Fig. 2-7 & ¶0128 - Based on the determined average Doppler shifts for each CSI-RS, UE 115-c may, for each signal path 405 (e.g., for each CSI-RS port group, CSI-RS resource, or CSI-RS resource set), select and report an index of a CSI-RS port or a CSI-RS resource indicator (CRI) (e.g., associated with a CSI-RS resource) corresponding to a lowest average Doppler shift (e.g., a lowest absolute average Doppler shift, a shift closest to a center frequency). In other words, UE 115-c may select and report an index of a CSI-RS port or CRI corresponding to a lowest average Doppler shift (e.g., lowest absolute average Doppler shift) from among CSI-RS ports or resources sharing a same spatial precoding (e.g., w.sub.n). For example, for signal path 405-a, UE 115-c may select and report an index of a CSI-RS port or CRI corresponding to a lowest average Doppler shift. Additionally, for signal path 405-b, UE 115-c may select and report an index of a CSI-RS port or CRI corresponding to a lowest average Doppler shift. Reporting the respective lowest average Doppler shifts (e.g., lowest absolute average Doppler shifts) may support aligning the respective Doppler shifts to a center frequency and to each other (e.g., reducing a span or scope between the respective Doppler shifts and the center frequency, between the respective Doppler shifts). Fig. 2-7 & ¶0151 - At 730, UE 115-e may transmit, to base station 105-e, signaling indicative of (e.g., an indication of) a first Doppler frequency shift and a second Doppler frequency shift. The first Doppler frequency shift may be based on an average of a first set of multiple Doppler frequency shifts associated with the first CSI-RS, and the second Doppler frequency shift may be based on an average of a second set of multiple Doppler frequency shifts associated with the second CSI-RS. Fig. 2-7 & ¶0153 - as described with reference to FIGS. 3A-3B and 4A-4B, the respective temporal and spatial precodings may be based on respective CSI reported by UE 115-e to base station 105-e, where the CSI may be based on CSI-RSs that are temporally and spatially precoded by base station 105-e using the indication of the first Doppler frequency shift and the second Doppler frequency shift.)
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Muruganathan’s invention of a system and a method for Channel State Information (CSI) reporting with angle and delay reciprocity in a wireless communication system to include Xi’s invention of a system and a method for temporal and spatial precoding of downlink signals in a wireless communication system, because it provides an efficient mechanism for reducing a time domain selectivity of downlink transmissions communicated via one or more signal paths (e.g., multiple signal paths) between a base station and a UE (user equipment) operating in the wireless communication system.
