Abstract: A user equipment (UE) includes a first subscriber identification module (SIM) and a second SIM. The UE is configured to establish a first cellular network connection based on, at least, the first SIM and a second cellular network connection based on, at least, the second SIM. The UE sends, by the first SIM, a first registration request to the network, wherein the first registration request comprises an identification indicating the multi-SIM device is a type of multi-SIM device, receives, by the first SIM, a first registration accept message indicating the first registration request has been accepted, wherein the first registration accept message comprises a first temporary identification for the first SIM and sends, by the second SIM, an access network message comprising one of the first temporary identification or a further temporary identification based on, at least, the first temporary identification.

Abstract: Devices, systems and methods for implementing beam failure management techniques at a user equipment (UE). The UE receives a timing advance command (TAC) from a currently camped cell and initiates a time advance timer (TAT). When the TAT is running the UE is in a first operating state. The first operating state indicates that the UE is in time alignment with the cell. The UE identifies that the TAT has expired. When the TAT is not running the UE is in a second operating state. The second operating state indicates that the UE is not in time alignment with the cell. The UE implements one or more beam failure management techniques based on the UE operating in the second operating state.

Abstract: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.

Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: The disclosure is related to handover methods in a wireless network. A user equipment (UE) may connect to a first next generation Node B (gNB) of a 5G new radio (NR) network. The UE may then receive a handover command from the first gNB via one of a Layer 1 signaling or Layer 2 signaling that instructs the UE to perform a handover procedure to handover to a second gNB. The UE may then conduct the handover procedure with the second gNB for the UE to connect to the second gNB. Correspondingly, the first gNB may instruct the UE to perform a handover procedure based on a handover command that is transmitted from the first gNB via one of a Layer 1 signaling or Layer 2 signaling, wherein the handover command comprises an identification of a Transmission and Configuration Indication (TCI) state that is associated with the second gNB.

Abstract: A user equipment (UE) is connected to a 5G New Radio (NR) network via a serving cell. The UE performs radio resource management (RRM) measurements on the serving cell, determines whether the UE satisfies power saving criteria for a first, second, or third mobility scenario while in a Radio Resource Control (RRC) idle state or RRC inactive state, wherein, when the UE is in the first or second mobility scenario, the UE performs RRM measurements with longer intervals relative to RRM measurements performed in a non-power-saving mode and wherein, when the UE is in the third scenario, the UE performs RRM measurements for neighbor cells with longer intervals relative to RRM measurements performed in a non-power-saving mode and determines a UE RRM configuration when the UE transitions from any of the power saving scenarios or the non-power-saving mode to any other power saving scenarios or the non-power-saving mode.

Abstract: A user equipment (UE) reports radio access capabilities to a network. The UE receives a request from a network for radio access capabilities of the UE, determining one or more radio access capabilities related to physical downlink control channel (PDCCH) blind decoding by the UE, generates a message that includes the one or more radio access capabilities of the UE and transmits the message to the network.

Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.
