Page 16, gNB under the CU/DU separation framework)
the network node comprising processing circuitry configured to: receive, at the (MN-DU), first signaling that request for a master cell group, MCG, configuration associated with a wireless device to be modified, the first signaling indicating that the request for the MCG configuration modification is based at least on a change in secondary cell group, SCG, configuration associated with the wireless device ;
(Fig. 12, page 16-17, step 2: gNB-CU sends a user terminal context modification request message to gNB-DU1, wherein the request message comprises the source MCG reconfiguration indicative of the target SCG. gNB-DU1 generates the cell group configuration information of the target SCG after switching, wherein the cell group identification information of the source MCG is included to indicate that the configuration information is the increment configuration information based on the source MCG configuration information. In other words, the MCG reconfiguration comprises the indication of the target SCG (SCG is being promoted to MCG, and replaces the original MCG reconfiguration). The DU receives signaling that directly reflects this change and applies the configuration updates based on the target SCG)
and modify, at the (MN-DU), the MCG configuration based at least on the change in the SCG configuration associated with the wireless device. (Page 16-17, step 2-3 of Fig. 12, gNB-DU1 generates the cell group configuration information of the target SCG after switching, wherein the cell group identification information of the source MCG is included to indicate that the configuration information is the increment configuration information.

In addition, the participant in the wireless access system also needs to perform some additional operations to ensure that the change operation of the Cell Group ID can be performed correctly and efficiently. See also step 2, step 6 and 7 of Fig. 12’s description)
As to claim 30:
Zhou in view of Yan Zhou discloses all limitations of claim 1, wherein the change in the SCG configuration corresponds to removing a SCG from the SCG configuration. (Zhou, page 12, step 1, the change in configuration occurred in step 1, wherein that change namely includes the promotion of the target SCG to be indicated as the new source MCG. Since the target SCG is now the new MCG, it is no longer part of the SCG configuration (i.e. removed), and secondly, the SCG itself is modified by virtue of being appointed as the new MCG)
As to claim 31:
Zhou in view of Yan Zhou discloses all limitations of claim 1, wherein the change in the SCG configuration corresponds to modifying a SCG associated with the SCG configuration. (Zhou, page 12, step 1, the change in configuration occurred in step 1, wherein that change namely includes the promotion of the target SCG to be indicated as the new source MCG.

Claim(s) 29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhou (CN 111510934) in view of Yan Zhou et al. (US 2022/0014983) and in view of Xu et al. (US 2020/0359450).
As to claim 29:
Zhou in view of Yan Zhou discloses all limitations of claim 1, wherein the cell group reconfiguration in in responses a change pertaining in the SCG per Fig. 12, however does not explicitly disclose one possible change corresponds to adding a SCG to the SCG configuration.
Xu, in a related field of cell group management, discloses in scenarios when a change occurs, namely when the MN adds, modifies, and releases (removes) a particular SCG, a configuration update request is made to ensure bearer context, UE context, and SCG configuration are updated to reflect said change (¶0117). (It is noted that, Xu covers all possible scenarios in original claim 3)
It would have been obvious to one of ordinary skill in the art before the effective filing time of the invention that the update of configuration pertaining a SCG in Zhou to include a trigger that corresponds to the adding of a SCG. This implementation ensures system transparency in both ends where network and user contexts are always up-to-date of real time changes responsive to network/mobility changes.
Claim(s) 8, 16, 22, and 28 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhou (CN 111510934) in view of Yan Zhou et al. (US 2022/0014983) in view of Teyeb et al. (US 2020/0128454).
As to claims 8, 16, 22, and 28:
Zhou in view of Yan Zhou discloses all limitations of claim 1/9/17/23, however is silent on the change in the SCG configuration indicates one of: a different subset of wireless device capabilities is being implemented; and that the MCG configuration is no longer restricted to at least one band combination.
Teyeb, in a related field of endeavor, discloses on the change in the SCG configuration indicates one of: a different subset of wireless device capabilities is being implemented; and that the MCG configuration is no longer restricted to at least one band combination, see ¶0228 and Table 10 of CG Config message, gNB to request the SgNB to perform certain actions e.g. to establish, modify or release an SCG. The message may include additional information e.g. to assist the SgNB to set the SCG configuration. It can also be used by a CU to request a DU to perform certain actions, e.g. to establish, modify or release an MCG or SCG”, also “ue-Capabilityinfo” which contain UE capability-container list which hold features of UE to be used adaptively.
It would have been obvious to one of ordinary skill in the art before the effective filing time of the invention that Zhou’s system to include at least one of: a different subset of wireless device capabilities is being implemented; and that the MCG configuration is no longer restricted to at least one band combination in manner disclosed by Teyeb. Both references aim to solve adjustment in MCG behavior without significant overhead/service interruption, such implementation advantageously lead to more resource allocation with the smart role swapping between SCG and MCG.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Futaki et al. (US 2019/0182716) - A radio access network (RAN) node (11) is configured to send, to another RAN node (12), first control information regarding at least one of one or more bandwidth parts (BWPs) configured in a system bandwidth. It is thus, for example, possible to contribute to inter-radio access network (RAN) node (e.g., inter-gNB) signaling enhanced to handle bandwidth parts.
