Abstract: Systems and methods provide secondary cell group (SCG) activation and deactivation. A user equipment (UE) in a wireless network may determine bandwidth part (BWP) configurations for a carrier of a primary secondary cell (PSCell) of an SCG for dual connectivity (DC). The UE may move between an SCG activation state and an SCG deactivation state based on the BWP configurations. SCG deactivation modeling may be based on a separate BWP configuration or may be modeled via a separate configuration in radio resource control (RRC) that is applicable to the BWPs in a serving cell.

Abstract: A user equipment (UE) operates in a network. The UE receives, from the network, a paging area comprising a plurality of cells of the network. When the UE is in one of a radio resource control (RRC) inactive state or RRC idle state with respect to the network, the UE transmits a message to a first cell of the paging area based on the UE moving into a first coverage area of the first cell from a second coverage area of a second cell of the paging area. The UE then monitors the first cell for a page from the network.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.

Abstract: A network reselection procedure, of a wireless communication device, that occurs following a network detachment event, such as a device sleep event or a device power savings mode event. The wireless communication device attempts to acquire a first wireless network to which the wireless communication device was most recently attached, immediately preceding the network detachment event. Then, in response to an unsuccessful acquisition of the first wireless network, the wireless communication device attempts an alternate network acquisition utilizing a Most Recently Used List (MRUL) that is stored at the wireless communication device and includes information about one or more frequency bands allocated to a primary service provider with which the wireless communication device is affiliated. After determining whether the alternate network acquisition attempt was successful, the wireless communication device attaches to a second network and stores information associated with the second network.
