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 4, 10 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al.

For NE-DC (eutra-SCG), mrdc-SecondaryCellGroup includes the E-UTRA RRCConnectionReconfiguration message as specified in TS 36.331 [10]. In this version of the specification, the E-UTRA RRC message can only include the field scg-Configuration.) before the releasing the BAP entity of the apparatus based on the reconfiguration message, the operations further comprise: (Section 5.3.5.3 … 1>if the RRCReconfiguration message includes the bap-Config: 2> perform the BAP configuration procedure as specified in 5.3.5.X;) releasing a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a last successfully configured BAP configuration that only exists on the apparatus (Section 5.3.5.3 … 1>if the RRCReconfiguration message includes the bap-Config: 2> perform the BAP configuration procedure as specified in 5.3.5.X;). The motivation regarding to the obviousness of claim 4 is also applied to claim 16. Claims 5, 11 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. ( U.S. PGPUB 2024/0187950), Kim hereinafter, in view of Yang. ( U.S. PGPUB 20250056647), Yang hereinafter and further in view of Ericsson “Running CR to 38.331 on Integrated Access and Backhaul for NR”, 3GPP Draft; R2-2002122, Ericsson hereinafter. Regarding Claim 5, Kim teaches claim 1. Yet, Kim does not expressly teach wherein the first node is in a new radio dual connectivity (NR DC) mode in an F1 interface control plane and F1 interface user plane split scenario; a secondary node (SN) is an F1 interface terminating donor node of the first node; a master node (MN) is a non-F1 interface terminating node of the first node; However, in the analogous art, Yang explicitly discloses wherein the first node is in a new radio dual connectivity (NR DC) mode in an F1 interface control plane and F1 interface user plane split scenario; ([0125] For example, when the MN generates the first RRC reconfiguration message, there is no need to introduce a new information element, first indication information non-F1-terminating, into the first RRC reconfiguration message, and the IAB node receives the first RRC reconfiguration message via SRB1. As it does not contain the first indication information, i.e. the IAB node does not receive the first indication information, the IAB node determines that at least one IP address configuration carried by the first RRC reconfiguration message is the IP address information of the F1-terminating topology domain. (III) For Dual-Connectivity Scenario 2) a secondary node (SN) is an F1 interface terminating donor node of the first node; ([0126] In some embodiments, FIG. 13 is a schematic diagram of dual-connectivity scenario 2. As shown in FIG. 13, in dual-connectivity scenario 2, the first IAB-donor (F1-terminating donor) is a secondary node SN of the IAB node, and the second IAB-donor (non-F1-terminating donor) is a master node MN of the IAB node.) a master node (MN) is a non-F1 interface terminating node of the first node; ([0126] In some embodiments, FIG. 13 is a schematic diagram of dual-connectivity scenario 2. As shown in FIG. 13, in dual-connectivity scenario 2, the first IAB-donor (F1-terminating donor) is a secondary node SN of the IAB node, and the second IAB-donor (non-F1-terminating donor) is a master node MN of the IAB node.) Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s Method and apparatus for handover of wireless backhaul node, which minimizes data downtime in next-generation mobile communication system to include Yang's F1 and non-F1 interface for improved network security and multi-vendor interoperability. Yet, Kim in view of Yang does not expressly teach the reconfiguration message indicates the first node to perform a multi-radio access technology (multi-RAT) dual connectivity (MR DC) release process; and before the releasing, by the first node, the BAP entity of the first node based on the reconfiguration message, the method further comprises: releasing, by the first node, a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a unique successfully configured BAP configuration that only exists on the first node. However, in the analogous art, Ericsson explicitly discloses the reconfiguration message indicates the first node to perform a multi-radio access technology (multi-RAT) dual connectivity (MR DC) release process; and (Sections of R0741 discloses reconfiguration message with multi-RAT and MR-DC. Section 5.3.5.3 … 1> if the RRCReconfiguration includes the mrdc-SecondaryCellGroupConfig: 2> if the mrdc SecondaryCellGroupConfig is set to setup: 3> if the mrdc-SecondaryCellGroupConfig includes mrdc-ReleaseAndAdd: 4> perform MR-DC release as specified in section 5.3.5.10; ... ) before the releasing, by the first node, the BAP entity of the first node based on the reconfiguration message, the method further comprises: (Sections of R0741 discloses reconfiguration message with BAP. Section 5.3.5.3 … 1>if the RRCReconfiguration message includes the bap-Config: 2> perform the BAP configuration procedure as specified in 5.3.5.X; … ) releasing, by the first node, a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a unique successfully configured BAP configuration that only exists on the first node (Section 5.3.5.X … 1> if the bap-config is set to release: 2> release the BAP entity at the IAB-MT as specified in [x]. …). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s Method and apparatus for handover of wireless backhaul node, which minimizes data downtime in next-generation mobile communication system to include Ericsson's dual connectivity and multi-RAT Integrated Access and Backhaul for NR for improved throughput and multi-RAT coexistence. Regarding Claim 11, Kim teaches claim 7. Yet, Kim does not expressly teach wherein the apparatus is in a new radio dual connectivity (NR DC) mode in an F1 interface control plane and F1 interface user plane split scenario; a secondary node (SN) is an F1 interface terminating donor node of the apparatus; a master node (MN) is a non-F1 interface terminating node of the apparatus; However, in the analogous art, Yang explicitly discloses wherein the apparatus is in a new radio dual connectivity (NR DC) mode in an F1 interface control plane and F1 interface user plane split scenario; ([0125] For example, when the MN generates the first RRC reconfiguration message, there is no need to introduce a new information element, first indication information non-F1-terminating, into the first RRC reconfiguration message, and the IAB node receives the first RRC reconfiguration message via SRB1. As it does not contain the first indication information, i.e. the IAB node does not receive the first indication information, the IAB node determines that at least one IP address configuration carried by the first RRC reconfiguration message is the IP address information of the F1-terminating topology domain. (III) For Dual-Connectivity Scenario 2) a secondary node (SN) is an F1 interface terminating donor node of the apparatus; ([0126] In some embodiments, FIG. 13 is a schematic diagram of dual-connectivity scenario 2. As shown in FIG. 13, in dual-connectivity scenario 2, the first IAB-donor (F1-terminating donor) is a secondary node SN of the IAB node, and the second IAB-donor (non-F1-terminating donor) is a master node MN of the IAB node.) a master node (MN) is a non-F1 interface terminating node of the apparatus; ([0126] In some embodiments, FIG. 13 is a schematic diagram of dual-connectivity scenario 2. As shown in FIG. 13, in dual-connectivity scenario 2, the first IAB-donor (F1-terminating donor) is a secondary node SN of the IAB node, and the second IAB-donor (non-F1-terminating donor) is a master node MN of the IAB node.) Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s Method and apparatus for handover of wireless backhaul node, which minimizes data downtime in next-generation mobile communication system to include Yang's F1 and non-F1 interface for improved network security and multi-vendor interoperability. Yet, Kim in view of Yang does not expressly teach the reconfiguration message indicates the apparatus to perform a multi-radio access technology (multi-RAT) dual connectivity (MR DC) release process; and before the releasing the BAP entity of the apparatus based on the reconfiguration message, the operations further comprise: releasing a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a unique successfully configured BAP configuration that only exists on the apparatus. However, in the analogous art, Ericsson explicitly discloses the reconfiguration message indicates the apparatus to perform a multi-radio access technology (multi-RAT) dual connectivity (MR DC) release process; and (Sections of R0741 discloses reconfiguration message with multi-RAT and MR-DC. Section 5.3.5.3 … 1> if the RRCReconfiguration includes the mrdc-SecondaryCellGroupConfig: 2> if the mrdc SecondaryCellGroupConfig is set to setup: 3> if the mrdc-SecondaryCellGroupConfig includes mrdc-ReleaseAndAdd: 4> perform MR-DC release as specified in section 5.3.5.10; ... ) before the releasing the BAP entity of the apparatus based on the reconfiguration message, the operations further comprise: (Sections of R0741 discloses reconfiguration message with BAP. Section 5.3.5.3 … 1>if the RRCReconfiguration message includes the bap-Config: 2> perform the BAP configuration procedure as specified in 5.3.5.X; … ) releasing a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a unique successfully configured BAP configuration that only exists on the apparatus (Section 5.3.5.X … 1> if the bap-config is set to release: 2> release the BAP entity at the IAB-MT as specified in [x]. …). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s Method and apparatus for handover of wireless backhaul node, which minimizes data downtime in next-generation mobile communication system to include Ericsson's dual connectivity and multi-RAT Integrated Access and Backhaul for NR for improved throughput and multi-RAT coexistence. Regarding Claim 17, Kim teaches claim 13. Yet, Kim does not expressly teach whereinthe apparatus is in a new radio dual connectivity (NR DC) mode in an F1 interface control plane and F1 interface user plane split scenario; a secondary node (SN) is an F1 interface terminating donor node of the apparatus; a master node (MN) is a non-Fl interface terminating node of the apparatus; However, in the analogous art, Yang explicitly discloses wherein the apparatus is in a new radio dual connectivity (NR DC) mode in an F1 interface control plane and F1 interface user plane split scenario; ([0125] For example, when the MN generates the first RRC reconfiguration message, there is no need to introduce a new information element, first indication information non-F1-terminating, into the first RRC reconfiguration message, and the IAB node receives the first RRC reconfiguration message via SRB1. As it does not contain the first indication information, i.e. the IAB node does not receive the first indication information, the IAB node determines that at least one IP address configuration carried by the first RRC reconfiguration message is the IP address information of the F1-terminating topology domain. (III) For Dual-Connectivity Scenario 2) a secondary node (SN) is an F1 interface terminating donor node of the apparatus; ([0126] In some embodiments, FIG. 13 is a schematic diagram of dual-connectivity scenario 2. As shown in FIG. 13, in dual-connectivity scenario 2, the first IAB-donor (F1-terminating donor) is a secondary node SN of the IAB node, and the second IAB-donor (non-F1-terminating donor) is a master node MN of the IAB node.) a master node (MN) is a non-Fl interface terminating node of the apparatus; ([0126] In some embodiments, FIG. 13 is a schematic diagram of dual-connectivity scenario 2. As shown in FIG. 13, in dual-connectivity scenario 2, the first IAB-donor (F1-terminating donor) is a secondary node SN of the IAB node, and the second IAB-donor (non-F1-terminating donor) is a master node MN of the IAB node.)

Yet, Kim in view of Yang does not expressly teach the reconfiguration message indicates the apparatus to perform a multi-radio access technology (multi-RAT) dual connectivity (MR DC) release process; and before the releasing the BAP entity of the apparatus based on the reconfiguration message, the operations further comprise: releasing a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a unique successfully configured BAP configuration that only exists on the apparatus. However, in the analogous art, Ericsson explicitly discloses the reconfiguration message indicates the apparatus to perform a multi-radio access technology (multi-RAT) dual connectivity (MR DC) release process; and (Sections of R0741 discloses reconfiguration message with multi-RAT and MR-DC. Section 5.3.5.3 … 1> if the RRCReconfiguration includes the mrdc-SecondaryCellGroupConfig: 2> if the mrdc SecondaryCellGroupConfig is set to setup: 3> if the mrdc-SecondaryCellGroupConfig includes mrdc-ReleaseAndAdd: 4> perform MR-DC release as specified in section 5.3.5.10; ... ) before the releasing the BAP entity of the apparatus based on the reconfiguration message, the operations further comprise: (Sections of R0741 discloses reconfiguration message with BAP. Section 5.3.5.3 … 1>if the RRCReconfiguration message includes the bap-Config: 2> perform the BAP configuration procedure as specified in 5.3.5.X; … ) releasing a BAP configuration associated with a secondary cell group (SCG), wherein the BAP configuration associated with the SCG is a unique successfully configured BAP configuration that only exists on the apparatus (Section 5.3.5.X … 1> if the bap-config is set to release: 2> release the BAP entity at the IAB-MT as specified in [x]. …).
