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.
5. Claims 1-2, 6-7, 10-11, and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Purkayastha et al., U.S. Patent Application Publication 2022/0116840 (hereinafter Purkayastha), in view of Da Silva et al., U.S. Patent Application Publication 2024/0098611 (hereinafter Da Silva), further in view of Kim et al., WO 2021075844 A1 (hereinafter Kim).
Regarding claim 1, Purkayastha discloses a method performed by a master node (MN) supporting a dual connectivity operation in a wireless communication system (disclosed is a method performed by a master node (MN) supporting dual connectivity, according to [0102], Fig. 7), the method comprising:
transmitting, to a target secondary node (SN), an SN addition request message for a conditional primary secondary cell (PSCell) change (CPC) including information on a plurality of candidate target PSCells (the MN transmits, to a target secondary node (T-SN), an SN Addition Request message that comprises a list of candidate target PSCells, as part of a conditional PSCell change procedure, according to [0102], [0107], Fig. 7 [step 720]);
receiving, from the target SN, an SN addition request acknowledge message including information on a target PSCell for the CPC which is selected from the plurality of candidate target PSCells (the MN receives, from the T-SN, an SN Addition Request Acknowledge message, comprising information on a target PSCell configuration, according to [0109], Fig. 7 [step 730]);
receiving, from the terminal, an RRC reconfiguration complete message transmitted in case that the CPC execution condition is satisfied (the MN receives, from a UE, an RRC Reconfiguration Complete message in a case wherein the condition for conditional PSCell addition has been satisfied, according to [0118]-[0119], Fig. 7 [steps 750 and 755]); and
transmitting, to a target SN, an SN reconfiguration complete message (the MN transmits, to the T-SN, an SN Reconfiguration Complete message, according to [0120], Fig. 7 [step 760]).
Purkayastha does not expressly disclose that the SN addition request message includes information on a plurality of candidate target PSCells suggested by the MN and information on measurement results for the plurality of candidate target PSCells, whereby a target PSCell is selected based on the information on the measurement results, nor transmitting, to a terminal, a radio resource control (RRC) reconfiguration message including conditional reconfiguration information for the CPC and measurement configuration information, wherein the conditional reconfiguration information for the CPC includes information for CPC execution condition, the information for CPC execution condition being indicated as a measurement identifier (ID), wherein the measurement configuration information includes information on a measurement object and information on a report configuration, the information on the measurement object and the information on the report configuration corresponding to the measurement ID, wherein the information on the report configuration includes event information corresponding to the CPC execution condition, and wherein the event information includes an event indicating that a measurement result for the target PSCell is greater than a threshold.

whereby a target PSCell is selected based on the information on the measurement results (the T-SN selects a set of candidate cells out of the candidate cells provided in the SN Addition Request using the CG-Config information, according to [0032], [0205]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Purkayastha with Da Silva such that the SN addition request message includes information on a plurality of candidate target PSCells suggested by the MN and information on measurement results for the plurality of candidate target PSCells.
One of ordinary skill in the art would have been motivated to make this modification in order to facilitate measurement gap coordination between a UE, MN, and SN (Da Silva: [0160]-[0162]).

wherein the event information includes an event indicating that a measurement result for the target PSCell is greater than a threshold (a measurement result for a cell must be better than a threshold in order for a report condition associated with an event to be satisfied, according to [155], [158], [163]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Purkayastha as modified by Da Silva with Kim by transmitting, to a terminal, a radio resource control (RRC) reconfiguration message including conditional reconfiguration information for the CPC and measurement configuration information, wherein the conditional reconfiguration information for the CPC includes information for CPC execution condition, the information for CPC execution condition being indicated as a measurement identifier (ID), wherein the measurement configuration information includes information on a measurement object and information on a report configuration, the information on the measurement object and the information on the report configuration corresponding to the measurement ID, wherein the information on the report configuration includes event information corresponding to the CPC execution condition, and wherein the event information includes an event indicating that a measurement result for the target PSCell is greater than a threshold.
