Abstract: A user equipment (UE) configured to operate in a radio resource control (RRC) connected state with a network cell, receive an RRC message to release or suspend the RRC connected state, the RRC message including an indication for a tracking reference signal (TRS) or channel state information reference signal (CSI-RS) configuration to use during an RRC inactive or idle state, enter the RRC inactive or idle state and apply the TRS or CSI-RS configuration for performing timing and frequency error estimation for decoding downlink control information.

Abstract: An approach is described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a second UE and a wireless device and a processor communicatively coupled to the transceiver. The processor is configured receive, from the second UE, an end-to-end (E2E) quality of service (QoS) requirement of an E2E connection between the second UE and the wireless device, wherein the E2E connection includes a first hop between the UE and the second UE and a second hop between the UE and the wireless device. The processor is further configured to obtain a first hop link condition and a second hop link condition; split the E2E QoS requirement into a first hop QoS requirement and a second hop QoS requirement based on the first hop link condition and the second hop link condition; and transmit, using the transceiver, the first hop QoS requirement to the second UE. The wireless device is a third UE or a base station.

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: 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.
