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
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.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
1. Claims 1, 15-16 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over D1 found in IDS 3/24/2025 and used in the EP option for EP 21940104 (3GfPP TSG-RAN WG2 Meeting #114, VIVO: “UE behavior when SCG is deactivated, publicly available 5/11/2021 at 3GPP.org) in view of Min (2024/0147543) or Min (2024/0214842).
Regarding claims 1, 16 and 20. D1 teaches a program and a method performed by a user equipment (UE) connected to a network, comprising: a processor; and a memory coupled with the processor, the processor configured to cause the UE to:
receive first configuration information from the a network (section 2.6 – PSCell addition with SCG deactivation, section 2.7 – PSCell change with SCG deactivation .. When the SCG is in deactivated state, the UE f(e.g., comprising processor and memory) can receive an SCG RRCReconfiguration message embedded in an MCG RRC Reconfiguration message on SRB1, like when the SCG is activated), wherein the first configuration information is associated with a primary secondary cell (PSCell) addition procedure or a PSCell change procedure for a secondary cell group (SCG) (section 2.6 – PSCell addition with SCG deactivation, section 2.7 – PSCell change with SCG deactivation. When the SCG is in deactivated state, the UE f(e.g., comprising processor and memory) can receive an SCG RRCReconfiguration message embedded in an MCG RRC Reconfiguration message on SRB1, like when the SCG is activated);
determine whether the PSCell addition procedure or the PSCell change procedure is successfully completed when the SCG is in a deactivated state (.7 – PSCell change with SCG deactivation .. When the SCG is in deactivated state, the UE (e.g., comprising processor and memory) can receive an SCG RRCReconfiguration message embedded in an MCG RRC Reconfiguration message on SRB1, like when the SCG is activated, and then the UE processes the SCG RRCReconfiguration message according to Rel 15/16 procedure (FFS if any restriction/difference) and UE sends a SCG RRCReconfigurationComplete message … according to Rel-15/16. Conditional PSCell change (CPC) has been specified in Rel. 16 when SCG is deactivated. If at least one CPC candidate PSCell satisfies the corresponding CPC execution condition, the UE detaches from the source PSCell, applies the stored corresponding configuration for the selected candidate PSCell and synchronizes to the candidate PSCell. The UE completes the CPC execution procedure by sending an RRCReconfigurationComplete message to the new PScell); and
D1 does not teach in response to determining that the PSCell addition procedure or the PSCell change procedure has failed, transmit failure information to the network.
Min ‘543 teaches UE comprises memory and processor (figure 3, 0019, 0058-0059) and provides a UE and radio communication method capable of efficiently utilizing resources for RACH even when adding or changing PSCell in a deactivated SCG (abstract, 0010, 0110 – each operation example assumes a case in which the state of SCG is configured to “deactivated” at the time of PSCell addition/change). Figure 7, 0124-0125 – UE executes the RA procedure with the target PSCell, but maintains the state of the SCG at deactivated (S220) thereafter, and determines whether or not the timer T 304 has expired (S230). The UE may release the dedicated RACH resource if the timer T 304 expires (S240). The UE executes the SCG failure information process (S250). Here, the UE may configure the failure cause to “SCGFailureWithDeactivatedState” and report the cell quality and/or beam quality of the deactivated SCG (PSCell) (0126).
Min ‘842 teaches UE comprising memory and processor (figure 3, 0013, 0048) and transmits a failure message “SCGFailureInformation” when failure occurs when SCG is in an inactive state (0058-0059, 0065, 0072). When the UE detects a radio link failures in the PSCell in the deactivated SCG state, it may transmit SCGFailureInformation, a RRC layer message, to the MN (figure 4, 0088-000095) wherein the contents of the SCGFailureInformation is depicted in figure 5 (0096-0106).
It would have been obvious for one of ordinary skill in the art before the effective filing date to modify D1 to transmit a CGFailureWithDeactivatedState message as taught by Min ‘543 or SCGFailureInformation” as taught by Min ‘842 when failure occurs when SCG is in an inactive/deactivate state thereby enabling the network to modify the conditional PSCell addition/change configurations based on the reported failure.
Regarding claim 15. D1 teaches a network device, comprising: a processor; and a memory coupled with the processor, a wireless transceiver coupled to the processor, wherein-the processor is configured to cause the network device to:
transmit, via the wireless transceiver, configuration information to a user equipment (UE) (section 2.6 – PSCell addition with SCG deactivation, section 2.7 – PSCell change with SCG deactivation .. When the SCG is in deactivated state, the UE can receive (e.g., from a network device comprising memory and processor) an SCG RRCReconfiguration message embedded in an MCG RRC Reconfiguration message on SRB1, like when the SCG is activated), wherein the configuration information is associated with a primary secondary cell (PSCell) addition procedure or the PSCell change procedure for a secondary cell group (SCG) section 2.6 – PSCell addition with SCG deactivation, section 2.7 – PSCell change with SCG deactivation. When the SCG is in deactivated state, the UE f(e.g., comprising processor and memory) can receive an SCG RRCReconfiguration message embedded in an MCG RRC Reconfiguration message on SRB1, like when the SCG is activated); and
D1 does not teach in response to receiving, via the wireless transceiver, failure information from the UE when the SCG is in a deactivated state, determine that the PSCell addition procedure or the PSCell change procedure has failed.
Min ‘543 teaches UE comprises memory and processor (figure 3, 0019, 0058-0059) and network device (figure 2, 0018, 0044 – eNB having processor and memory) and provides a UE and radio communication method capable of efficiently utilizing resources for RACH even when adding or changing PSCell in a deactivated SCG (abstract, 0010, 0110 – each operation example assumes a case in which the state of SCG is configured to “deactivated” at the time of PSCell addition/change). Figure 7, 0124-0125 – UE executes the RA procedure with the target PSCell, but maintains the state of the SCG at deactivated (S220) thereafter, and determines whether or not the timer T 304 has expired (S230). The UE may release the dedicated RACH resource if the timer T 304 expires (S240). The UE executes the SCG failure information process (S250). Here, the UE may configure the failure cause to “SCGFailureWithDeactivatedState” and report the cell quality and/or beam quality of the deactivated SCG (PSCell) (0126).
Min ‘842 teaches UE comprising memory and processor (figure 3, 0013, 0048) and a network device (figure 2, 0018, 0044 comprising memory and processor) and the UE transmits a failure message “SCGFailureInformation” when failure occurs when SCG is in an inactive state (0058-0059, 0065, 0072). When the UE detects a radio link failures in the PSCell in the deactivated SCG state, it may transmit SCGFailureInformation, a RRC layer message, to the MN (figure 4, 0088-000095) wherein the contents of the SCGFailureInformation is depicted in figure 5 (0096-0106).
It would have been obvious for one of ordinary skill in the art before the effective filing date to modify D1 to transmit, to a network device, a failure message as taught by Min ‘543 or SCGFailureInformation” as taught by Min ‘842 when failure occurs when SCG is in an inactive/deactivate state thereby enabling the network device to modify the conditional PSCell addition/change configurations based on the reported failure.
2. Claims 2-5, 17, and 21-22 are rejected under 35 U.S.C. 103 as being unpatentable over D1 in view of Min (2024/0147543) or Min (2024/0214842) further in view of Wang et al (2023/0232494).

Wang teaches SCG in deactivated state and UE transmits a failure message when PSCell add or change configuration is failed (0010, 0100, 0103). The network provides the UE with a list of PSCell(s) with execution conditions enabling the UE to evaluate PSCell(s) and conditions even when SCG is deactivated (0129, 0131,0135, 0146-0148, 0151).
It would have been obvious for one of ordinary skill in the art before the effective filing date to modify D1 in view of Min ‘543 or Min ‘842 to provide the UE with a list of PSCell(s) with execution conditions as taught by Wang enabling the UE to evaluate PSCell(s) and conditions even when SCG is deactivated.
Regarding claims 3 and 22. D1 in view or Min ‘543 or Min ‘842 do not teach, wherein the processor is further configured to cause the UE to select the target PSCell by selecting the target PSCell from one or more candidate PSCells within the list of candidate PSCells, and wherein each candidate PSCell in the one or more candidate PSCells fulfills an execution condition of the conditional PSCell change procedure.

Wang teaches SCG in deactivated state and UE transmits a failure message when PSCell add or change configuration is failed (0010, 0100, 0103). The network provides the UE with a list of PSCell(s) with execution conditions enabling the UE to evaluate PSCell(s) and conditions even when SCG is deactivated (0129, 0131,0135, 0146-0148, 0151).
Wang further teaches the MN and SNs exchange activity state (such as activation or deactivation) information (0059, 0069, 0085, 0090) and based on the actual/current state (activation/deactivation) of the SCG, the network performs reasonable subsequent processing based on the actual activity state of the SCG. For example, the network makes decision on whether to configure the SCG in the UE or change to another SN (0080).

It would have been obvious for one of ordinary skill in the art before the effective filing date to modify D1 in view of Min ‘543 or Min ‘842 to start/stop Timer T304 relating to SCG and target PSCell states as taught by Zhang.
4. Claims 10 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over D1 in view of Min (2024/0147543) or Min (2024/0214842) and Zhang further in view of Kim et al (2022/0022067).
Regarding claim 10. D1 in view or Min ‘543 or Min ‘842 and Zhang do not teach wherein the processor is further configured to cause the UE to further comprising: in response to not starting the handover timer, starting start a second timer, wherein the second timer is different from the handover timer.
Kim teaches using a first, second or third timer to perform different operations
according to the SCG in an active state, deactivated state, suspend, and/or resume
(0752) wherein first timer for determining whether SCG was successfully added,
resumed or activated, the second timer for determining whether a radio link with a cell
group (MCG or SCG) or a cell (Pcell) or PSCell is valid and a third timer is an auxiliary
timer for determining whether a radio link with a cell group (MCG or SCG) or Pcell or
