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: A base station may restrict access by a user equipment (UE). The base station broadcasts access restrictions to one or more UE within a cell coverage area of the base station, wherein the access restrictions include one or more predetermined criteria that must be satisfied for a UE to be allowed to camp on the base station. The base station performs a random access channel (RACH) procedure to allow the UE to camp on the base station when the UE satisfies the one or more predetermined criteria.

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: 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) is configured to enter a radio resource control (RRC) CONNECTED state on a first network using a first subscriber identification module (SIM) and an RRC INACTIVE or RRC IDLE state on a second network using a second SIM, transmit, to the first network, a request for a scheduling gap (SG) configuration, wherein, during a duration of the SG, the first network avoids scheduling resources for the UE, receive, from the first network, an indication of the SG configuration to be used, during the duration of the SG, tune away from the first network to perform operations on the second network and after the duration of the SG, tune back to the first network, wherein the RRC CONNECTED state is maintained on the first network during the duration of the SG.

Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential that was generated for a procedure between the UE and a network. The UE then generates an identifier corresponding to the first credential and generates a message authentication code based on the first credential and a count, wherein the count is associated with an identifier of an edge network client running on the UE. The UE then transmits an application registration request, message to a server associated with an edge data network, the application registration request message including the count, the message authentication code, the identifier corresponding to the first credential, and a public land mobile network identifier (PLMN ID) of the network. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.
