Abstract: Techniques to protect a subscriber identity, by encrypting a subscription permanent identifier (SUPI) to form one-time use subscription concealed identifiers (SUCIs) using a set of one-time ephemeral asymmetric keys, generated by a user equipment (UE), and network provided keys are disclosed. Encryption of the SUPI to form the SUCIs can mitigate snooping by rogue network entities, such as fake base stations. The UE is restricted from providing the unencrypted SUPI over an unauthenticated connection to a network entity. In some instances, the UE uses a trusted symmetric fallback encryption key KFB or trusted asymmetric fallback public key PKFB to verify messages from an unauthenticated network entity and/or to encrypt the SUPI to form a fallback SUCIFB for communication of messages with the unauthenticated network entity.

Abstract: A method performed by a user equipment (UE) is described. The method includes establishing a connection to a network that includes discontinuous reception (DRX) cycles, each DRX cycle including a scheduled OnDuration and a wake up signal (WUS) opportunity corresponding to each of the scheduled OnDurations, when a WUS is received in the WUS opportunity for one of the scheduled OnDurations, configuring the UE to utilize an active mode of processing during the one of the scheduled OnDurations and when a WUS is not received in the WUS opportunity for one of the scheduled OnDurations, configuring the UE to utilize a sleep mode of inactivity during the one of the scheduled OnDurations.

Abstract: A relay user equipment (UE) configured to operate as a relay between a remote UE and a network component performs a method. The method includes determining at least one relay capability of the relay UE and performing a relay access control operation that indicates to the remote UE whether the remote UE is permitted to use the relay UE as the relay.

Abstract: A multi-universal subscriber identity module (MUSIM) user equipment (UE) is configured to stay synchronized with a network. The UE registers to a first network for the first SIM, registering to a second network for the second SIM, prior to the UE conducting a high priority activity related to the second SIM, sends, to the first network via a connection associated with the first SIM, a first message comprising an estimated time duration during which the UE conducts the high priority activity related to the second SIM, receives, from the first network, a second message indicating a time period during which the first network will retain a connection context for the connection associated with the first SIM in an RRC Inactive state and when the UE completes the high priority activity, determines the connection context of the first network for the connection associated with the first SIM.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), determines that the dormant BWP is configured in an active state and performing one or more actions corresponding to the dormant BWP.

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 network configures and transmits paging information. The network transmits configuration information to a user equipment (UE) operating in the network, wherein the configuration information comprises a value N based on a minimum gap between reception of a paging downlink control information (DCI) by the UE and fully processing the paging DCI by the UE, configures a paging DCI to be transmitted to the UE on a Physical Downlink Control Channel (PDCCH), wherein the paging DCI includes scheduling information for a Physical Downlink Shared Channel (PDSCH) and transmits the paging DCI to the UE on the PDCCH.

Abstract: A network may provision a user equipment (UE) with charging rules for the UE to host sidelink (SL) communications with other UEs. An application server may receive information indicating a group of user equipment (UE) has been formed, the group of UEs comprising a first UE connected to a radio access network (RAN) and at least one further UE connected via a sidelink (SL) to the first UE, select SL parameters including session management parameters and charging parameters for a SL session for the UE group and provision a policy control function (PCF) of a core network (CN) with the selected SL parameters.
