Abstract: This disclosure relates to techniques for network slice selection. A network slice selection function of a cellular network may receive a network slice selection request from a radio access network node of the cellular network. The network slice selection request may be received by the radio access network node from a wireless device. A core network slice (and possibly a radio access network slice) of the cellular network may be selected for the service request. A network slice selection response may be provided to the radio access network node, indicating a control plane entry point address for the selected core network slice. The selected radio network slice may also be indicated in the network slice selection response.

Abstract: Apparatuses, systems, and methods for a wireless device to perform master cell group failure recovery in a dual connectivity cellular communication system. The wireless device may establish a first wireless link to a cellular network via a first cell group. The first cell group may be configured as a master cell group for the wireless device. The wireless device may establish a second wireless link to the cellular network via a second cell group. The second cell group may be configured as a secondary cell group for the wireless device. The wireless device may determine that link failure for the first wireless link has occurred. The wireless device may perform master cell group link failure recovery using the second wireless link based at least in part on the link failure for the first wireless link.

Abstract: This disclosure relates to techniques for supporting asymmetric uplink and downlink bandwidth allocations for a wireless device, and for dynamically modifying the bandwidth allocations for a wireless device, in a wireless communication system. A cellular communication link may be established between a base station and a wireless device. The base station may determine an uplink bandwidth allocation and a downlink bandwidth allocation for the wireless device. The uplink bandwidth allocation and the downlink bandwidth allocation may be selected based on different criteria and may include different amounts of bandwidth. Indications of the uplink bandwidth allocation and the downlink bandwidth allocation may be provided to the wireless device. The base station and wireless device may communicate according to the uplink bandwidth allocation and the downlink bandwidth allocation.

Abstract: Apparatuses, systems, and methods for a wireless device to perform enhanced duplication handling and/or failure handling procedures with a network, including one or more base station. The wireless device may connect to a network using multiple paths. The wireless device may autonomously determine whether to duplicate one or more transmissions to the network on the multiple paths. In the event of a radio link control failure associated with one bearer, the wireless device may suspend transmission of the failed bearer while continuing to use one or more other bearers for transmission.

Abstract: Apparatuses, systems, and methods to perform attachment of a wireless device to a next generation gateway via either a base station of a next generation radio access network (RAN) or a mobility management entity of a legacy RAN. An apparatus may be configured to receive an attachment request from a wireless device, determine authentication information via communication with a home subscriber server, determine, based at least in part on the authentication information, whether the wireless device is capable of communicating via the next generation RAT, and send, in response to determining the wireless device is capable, a connection request to a gateway of the next generation RAN. The authentication information may include subscription information associated with the wireless device.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: Apparatuses, systems, and methods for a wireless device to detect intermodulation issues and configure a transmission scheme to remedy detected intermodulation issues. The wireless device may perform measurements on a downlink carrier while one uplink carrier is scheduled for the wireless device. The wireless device may also perform measurements on the downlink carrier while two uplink carriers are scheduled for the wireless device. The wireless device may provide information based on those measurements to a serving base station. The base station may determine that an intermodulation issue is occurring at the wireless device based on the information provided, and may configure the wireless device to use a single uplink carrier at a time based at least in part on the intermodulation issue.

Abstract: This disclosure relates to techniques for performing network initiated downlink data transmissions with a wireless device in a cellular network. According to some embodiments, a wireless device and a cellular network may perform an attach procedure. As part of the attach procedure, the wireless device may indicate to the cellular network to store context information associated with the wireless device after the attach procedure is completed and the wireless device transitions to idle mode. The wireless device may also store context information. The stored context information may be used in conjunction with a network initiated downlink data transaction between the cellular network and the wireless device.
