DETAILED ACTION
1. Claims 1-3, 5-9, 11-15, 17, and 18 have been examined and are pending.
Priority
2. Acknowledgment is made of applicant's claim for foreign priority under 35 U.S.C. 119(a)-(d).
Response to Amendment
3. In response to the amendments received in the Office on 12/16/2025, the Office acknowledges the current status of the claims: claims 1, 3, 5, 7, 9, 11, 13, 15, and 15 have been amended, claims 4, 10, and 16 have been canceled, and no new matter appears to be included.
Response to Arguments
4. Applicant’s arguments with respect to claims 1-3, 5-9, 11-15, 17, and 18 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Claim Rejections - 35 USC § 103
5. 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 (i.e., changing from AIA to pre-AIA ) 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.
6. 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.
7. The factual inquiries 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.
8. Claims 1-3, 5-9, 11-15, 17, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application Publication 2021/0184810 A1 to Bai et al. (hereinafter “Bai”) in view of United States Patent Application Publication 2023/0088818 A1 to Chou et al. (hereinafter “Chou”).
Regarding Claim 1, Bai discloses a method of operating a user equipment (UE) in a mobile communication system, the method comprising:
receiving a radio resource control (RRC) configuration (Bai: [0062] – “The operations 500 may begin, at block 505, with UE receiving a configuration (e.g., via RRC signaling) of trigger states for CSI-RS reporting (e.g., aperiodic CSI-RS reporting).”);
receiving channel state information-reference signal (CSI-RS) (Bai: Figure 5, step 515; Figure 7, step 715; Figure 8, step 813; see also [0062] – “At block 515, the UE may receive the CSI-RS in accordance with the activated one of the trigger states, and at block 520, process the CSI-RS.”); and
performing CSI feedback after receiving the RRC configuration and the CSI-RS (Bai: Figure, step 525; Figure 7, step 725; Figure 8, steps 816, 824; see also [0062] – UE receives the RRC then the CSI-RS before performing CSI feedback.), wherein at least one of the CSI-RS reception and the CSI feedback is triggered by receiving downlink control information (DCI) (Bai: Figure 5, step 510; Figure 8, step 810), wherein the RRC configuration includes at least one sub-configuration associated with the CSI feedback (Bai: [0062-0064] – corresponds to multiple trigger states and content, received in the RRC, that indicate multiple different trigger states.).
Although Bai discloses sub-configurations of RRC configurations, and that these configurations include multiple trigger-state configurations, Bai does not expressly disclose wherein each sub-configuration is related to antenna adaptation, and defined in a bitmap form.
However, these features cannot be considered new or novel in the presence of Chou. Chou is similarly concerned with feedback of channel state information (CSI) based on CSI reference signals (CSI-RS, Chou: [0003]). Chou discloses wherein each sub-configuration is related to antenna adaptation, and defined in a bitmap form (Chou: [0097-0101] – corresponds to multiple different RRC configurations comprising one or more different types of CSI information for feedback, some in particular to one or more panel (antenna) configurations; see also [0020], [0129], [0160] – the gNB can indicate one or more of the antenna type configurations in a bitmap, “…the gNB can select the preferred combinations of TRPs with at least one bitmap or indicator in the CSI report configuration.”.).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to modify the configuration of Bai in view of the configuration of Chou to include an antenna adaptation via a bitmap for the reasons of properly identifying resources for measurement.
Regarding Claim 2, the combination of Bai and Chou discloses the method of claim 1, wherein Bai further discloses the DCI is received through a UE dedicated physical downlink control channel (PDCCH) (Bai: [0045], [0054-0055] – PDCCH is utilized for the transmission of control information, including DCI.).
Regarding Claim 3, the combination of Bai and Chou discloses the method of claim 1, wherein Bai further discloses the DCI comprising parameter information associated with network energy, and the parameter information saving is defined in a bitmap form (Bai: [0055] – corresponds to new or existing bit fields of DCI to transmit trigger information. Chou: [0097-0101] – corresponds to multiple different RRC configurations comprising one or more different types of CSI information for feedback, some in particular to one or more panel (antenna) configurations; see also [0020], [0129], [0160] – the gNB can indicate one or more of the antenna type configurations in a bitmap, “…the gNB can select the preferred combinations of TRPs with at least one bitmap or indicator in the CSI report configuration.”.).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to modify the configuration of Bai in view of the configuration of Chou to include an antenna adaptation via a bitmap for the reasons of properly identifying resources for measurement.
Regarding Claim 5, the combination of Bai and Chou discloses the method of claim 3, wherein Bai further discloses the parameter information associated with the network energy saving comprises CSI-RS transmission frequency information (Bai discloses these parameters may include [0054-0055] corresponding to a frequency of CSI-RS reporting (aperiodic) and how it is reported (beam). See also [0064].).
Regarding Claim 6, the combination of Bai and Chou discloses the method of claim 1, wherein Bai further discloses at least one of the CSI-RS reception and the CSI feedback is triggered after a certain amount of time, after receiving the DCI (Bai: [0062] – corresponds to the DCI indicating the scheduled CSI-RS using the activated one of the trigger states.).
Regarding Claim 7, Bai discloses a method of operating a base station in a mobile communication system, the method comprising:
transmitting a radio resource control (RRC) configuration (Bai: [0062] – “The operations 500 may begin, at block 505, with UE receiving a configuration (e.g., via RRC signaling) of trigger states for CSI-RS reporting (e.g., aperiodic CSI-RS reporting).” Since the UE receives the configuration, the base station has therefore transmitted the configuration.);
transmitting channel state information-reference signal (CSI-RS) (Bai: Figure 4, step 405; Figure 5, step 515 (implicitly disclosing “transmitting”); Figure 6, step 605; Figure 7, steps 705, 715 (implicitly disclosing “transmitting”); Figure 8, steps 813, 821; see also [0062] – “At block 515, the UE may receive the CSI-RS in accordance with the activated one of the trigger states, and at block 520, process the CSI-RS.”); and
receiving CSI feedback after transmitting the RRC configuration and the CSI-RS (Bai: Figure 4, step 415; Figure 5, step 525 (implicitly disclosing “receiving”); Figure 6, step 615; Figure 7, step 725 (implicitly disclosing “receiving”); Figure 8, steps 816, 824; see also [0062] – UE receives the RRC then the CSI-RS before performing CSI feedback.), wherein at least one of the CSI-RS transmission and the CSI feedback reception is triggered by transmitting downlink control information (DCI) (Bai: Figure 5, step 510; Figure 8, step 810), wherein the RRC configuration includes at least one sub-configuration associated with the CSI feedback (Bai: [0062-0064] – corresponds to multiple trigger states and content, received in the RRC, that indicate multiple different trigger states.).
Although Bai discloses sub-configurations of RRC configurations, and that these configurations include multiple trigger-state configurations, Bai does not expressly disclose wherein each sub-configuration is related to antenna adaptation, and defined in a bitmap form.
However, these features cannot be considered new or novel in the presence of Chou. Chou is similarly concerned with feedback of channel state information (CSI) based on CSI reference signals (CSI-RS, Chou: [0003]). Chou discloses wherein each sub-configuration is related to antenna adaptation, and defined in a bitmap form (Chou: [0097-0101] – corresponds to multiple different RRC configurations comprising one or more different types of CSI information for feedback, some in particular to one or more panel (antenna) configurations; see also [0020], [0129], [0160] – the gNB can indicate one or more of the antenna type configurations in a bitmap, “…the gNB can select the preferred combinations of TRPs with at least one bitmap or indicator in the CSI report configuration.”.).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to modify the configuration of Bai in view of the configuration of Chou to include an antenna adaptation via a bitmap for the reasons of properly identifying resources for measurement.
Claims 8, 9, 11 and 12, dependent upon claim 7, recites similar features as claims 2, 3, 5, and 6, respectively, and are therefore rejected upon the same grounds as claims 2, 3, 5, and 6. Please see above rejections of claims 2, 3, 5, and 6.
Claims 13-15, 17, and 18, directed to an apparatus embodiment of claims 1, 2, 3, 5, and 6, recite similar features as claims 1, 2, 3, 5, and 6, respectively, and are therefore rejected upon the same grounds as claims 1, 2, 3, 5, and 6. Please see above rejections of claims 1, 2, 3, 5, and 6. Bai further discloses the apparatus as a user device comprising at least one processor and at least one memory in at least Figure 9 with [0078-0082].
