    Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station, and a processor communicatively coupled to the transceiver. The processor is configured to enter a radio resource control (RRC) idle mode. The processor is further configured to measure at least one cell of a set of cells in a sleep period, wherein the sleep period is indicated in a discontinuous reception (DRX) configuration message received from the base station. The processor is further configured to receive a UE information request from the base station responsive to entering an RRC connected mode and transmit results of the measurement to the base station responsive to the UE information request to enable faster carrier addition by a network the UE connects to.

    Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

    Abstract: A network component of a radio access network (RAN) is configured to provide network slice information to a user equipment (UE). The network component receives an indication that a user equipment (UE) is requesting to access a network slice, determines a frequency associated with the network slice, identifies a cell within the RAN that operates on the frequency associated the network slice and transmits a message to the UE, wherein the message indicates the cell within the RAN that operates on the frequency associated with the network slice.

    Abstract: Activation or update of a subscriber identity module (SIM) via a roaming cellular wireless network by a mobile device includes the mobile device: determining a country of origin associated with a mobile network operator (MNO) for the SIM, determining a current geographic location of the mobile device, and when the current geographic location of the mobile device does not correspond to the country of origin for the MNO associated with the SIM of the eUICC, presenting an option to activate or update the SIM over a local roaming cellular wireless network. When the option is accepted, the mobile device enables a cellular data roaming capability for the mobile device, activates or updates the SIM via the local roaming cellular wireless network, and, after the SIM is activated or updated, disables the cellular data roaming capability for the mobile device.
