Abstract: Some embodiments include a system, method, and computer program product for managing power consumption of a user equipment (UE) supporting sidelink discontinuous reception (SL-DRX) in a 5G wireless communications system. A UE determines a candidate slot for sending a signal based on data sensed in various periods over a history window. Some embodiments include a processor that can determine set of candidate slots that are sufficiently sensed based on sensed periods over a history window, and determine a subset of candidate slots of the set of candidate slots based at least on an occupancy threshold over the history window. The processor can select a candidate slot from the subset of candidate slots, and transmit via the transceiver, a first signal via the selected candidate slot.

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: Embodiments are disclosed for application function (AF) initiated multicast session join procedures for multicast broadcast services (MBS), where a user equipment (UE) initiates the session leaving procedure. An AF server can receive a request from the UE to fetch content, and determine that the content is provided by the AF server via a multicast session of a MBS. The AF server can transmit another request to a core network (e.g., a next generation core network) to enable the UE to join the multicast session of the MBS. If the UE does not already have a protocol data unit (PDU) session to a Data Network Name/Single Network Slice Selection Assistance Information (DNN/S-NSSAI) providing the multicast session of the MBS, the AF server can invoke application triggering and/or application level redirection to enable the UE to access an AF instance on the DNN/S-NSSAI providing the multicast session of the MBS.

Abstract: A user equipment (UE) is grouped into a paging subgroup for the purposes of receiving pages from a network. The UE receives, from the network, a paging configuration for a Radio Resource Control (RRC) idle state or an RRC inactive state paging operation, the paging configuration comprising a paging subgroup identification for the UE and monitors paging occasions based on at least the paging subgroup identification.

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 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: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

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.
