Abstract: Techniques are described to generate a first security key when a user equipment operating in an inactive state initiates a data transmission or a procedure to resume network connection. The first security key is generated based on a second security key associated with a first network node and a counter value, and the first security key is associated with a second network node and is used to generate user plane security keys to transmit data to or to receive data from one or more network nodes.

Abstract: The present document describes methods, systems, and devices for configuring a measurement object in a wireless communication network. A plurality of candidate serving cell measurement object (MO) identifiers (IDs) are provided from a centralized unit (CU) to a distributed unit (DU). A a serving cell MO is selected by the DU from the plurality of candidate serving cell MO IDs to be used for a user equipment (UE). A per-bandwidth part (BWP) serving cell MO configuration is configured by the DU according to the serving cell MO.

Abstract: This disclosure relates generally to adaptive and dynamic paging resource selection and System Information (SI) acquisition in a wireless communication network. Performed by a first network element in a network, the method including: receiving a first message from a second network element of the network; deriving a User Equipment (UE) specific paging resource configuration associated with a UE based on the first message; selecting a paging radio resource based on the UE specific paging resource configuration and based on a radio resource specific paging configuration pre-defined in the first network element; and sending a paging message over the selected paging radio resource to the UE while the UE is in a radio resource control (RRC) inactive state.
