    Abstract: Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.

    Abstract: A WTRU may be configured to perform radio link monitoring (RLM) based on RLM reference signals (RLM-RSs) transmitted in a cell operating in an unlicensed spectrum. The WTRU may evaluate a radio link failure (RLF) status for the cell using a first RLM criteria based on the RLM-RSs. A transmission instance of the RLM-RSs may be skipped, for example, due to a listen before talk (LBT) failure at a gNodeB (gNB). The WTRU may adapt or change the first RLM criteria and/or evaluate the RLF status of the cell operating in the unlicensed spectrum using a second RLM criteria based on determining that the transmission instance of the RLM-RSs was skipped. The first RLM criteria may correspond to a first RLM process that utilizes a first set of RLM parameters. The second RLM criteria may correspond to a second RLM process that utilizes a second set of RLM parameters.

    Abstract: A wireless transmit receive unit (WTRU) may operate in a dual connectivity (DC) context. While in a RRC_INACTIVE state, the WTRU may receive a paging message from a first cell, which may be associated with a master cell group (MCG). The paging message may indicate that the WTRU is to respond to the paging message on another cell. Also, or alternatively, the paging message may indicate that data for the WTRU is available on an SCG bearer. The WTRU may select a second cell (e.g., a cell other than the first cell) from a secondary cell group (SCG) list, which may include one or more secondary cells. The WTRU may initiate a random access channel procedure with the second cell based on receiving the paging message from the first cell. The WTRU may receive data from the second cell via the SCG bearer while in the RRC_INACTIVE state.
