Abstract: A user equipment (UE) communicates with a further UE via a sidelink and communicates with a cell of a network via an uplink. The UE receives a hybrid automatic repeat request (HARQ) acknowledgement (ACK) timing parameter from the network, generates a sidelink HARQ-ACK codebook based on a signaling exchange with the further UE, wherein the sidelink HARQ-ACK codebook is constructed in decreasing order of one or more physical sidelink shared channel (PSSCH) transmission slots associated with a configured physical sidelink feedback channel (PSFCH) occasion, and transmits an indication of the sidelink HARQ-ACK codebook to the cell of the network.

Abstract: A network component communicating with a user equipment (UE) and a server. The network component receives a first packet from the UE, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, receives a second packet from the server and determines whether to transmit a signal to the UE based on the second packet received from the server. A UE having a transceiver and a processor. The UE transmits a first packet to the network component, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, identifies an out of service (OOS) event, receives registration information from the network component and registers with the server based on the registration information received from the network component.

Abstract: Techniques to protect subscriber identity in messages communicated between a user equipment (UE) and a cellular wireless network entity by using multiple ephemeral asymmetric keys are disclosed. The UE determines multiple ephemeral UE public and secret key pairs, while the cellular wireless network entity provides a network public key to the UE. The network public key may be updated over time. Multiple encryption keys based on the multiple ephemeral UE secret keys and the public network key are derived and used to encrypt a subscription permanent identifier (SUPI) to generate multiple subscription concealed identifiers (SUCIs). Each SUCI is used only once for messages communicated to a cellular wireless network and discarded after use. New SUCI are generated when the network public key is updated.

Abstract: A device, system, and method performs a Voice over Long Term Evolution (LTE) (VoLTE) call setup procedure. The device includes a transceiver establishing a connection with a LTE network and an Internet Protocol (IP) Multimedia Subsystem (IMS). The device includes a processor executing a VoLTE call application with a further user equipment, receiving an input to execute the VoLTE call application, and generating a data packet including an indication to trigger a dedicated bearer establishment procedure. The transceiver transmits the data packet to one of the LTE network and the IMS. The indication triggers the dedicated bearer establishment procedure to be performed during a Session Initiation Protocol (SIP) signal exchange procedure.
