Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.

Abstract: Systems, apparatuses, and methods for notification support in extended discontinuous reception mode. A base station and UE may configure eDRX communication. An indication may be received during the eDRX communication. The network may cache the indication. The network may modify the DRX configuration. The network may use a wake up signal. In response, the UE may receive the indication while achieving power savings from the eDRX configuration.

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: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for non-stand-alone unlicensed band cells that support single carrier capable UEs. A UE may camp on a licensed band cell of a RAN and transmit a request to connect. The UE may receive, from the licensed band cell, a connection setup message indicating a switch to an unlicensed band cell of the RAN and receive, from the unlicensed band cell, a reference signal. The UE may transmit to the unlicensed band cell and in response to confirming, based at least in part of the reference signal, radio quality and/or downlink timing of the unlicensed band cell, a connection complete/connection resume message.
