1. An apparatus, comprising: at least one processor configured to cause a master node to:
encode radio-resource control (RRC) signaling to provide information for configuring a User Equipment (UE) with a configuration for a secondary cell group (SCG) for dual connectivity to allow the UE to utilize radio resources of both a master cell group (MCG) associated with the master node and the SCG, the SCG associated with a secondary node;
determine, based on inactivity of the UE, a transition of the UE from an RRC connected mode to an RRC inactive mode; and
encode, for transmission to the secondary node, a secondary node request message that indicates suspension of the dual connectivity based on the determination of the transition of the UE from the RRC connected mode to the RRC inactive mode;
decode, from the secondary node, a confirmation of the secondary node request message;
decode, from the secondary node, a message based on data activity for the UE; and
encode, for transmission to the secondary node, a resume message to the secondary node.
