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: Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In some embodiments, the information transmitted to the network distinguishes between voice communications and other communications (e.g., other IMS communications) and is transmitted prior to establishment of a dedicated bearer for IP multimedia subsystem (IMS) signaling for the apparatus.

Abstract: This disclosure relates to techniques for establishing radio resource control connections between wireless devices and cellular networks. According to some embodiments, a wireless device and a cellular base station may establish a radio resource control (RRC) connection. The wireless device may indicate to the cellular base station to store access stratum context information associated with the wireless device after the RRC connection is released. The wireless device may also store access stratum context information associated with the cellular base station. The stored access stratum context information may be used in conjunction with a subsequent RRC connection establishment procedure between the wireless device and the cellular base station.

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: Apparatus and methods for managing use of radio frequency channels in unlicensed radio frequency bands by a wireless communication device in communication with a cellular wireless network are disclosed. The wireless communication device obtains, from an eNodeB of the wireless network, one or more access network discovery and selection function (ANDSF) policies that include rules for mobility of the wireless communication device and offloading of traffic for the wireless communication device to radio frequency channels in an unlicensed radio frequency band. The wireless communication device determines when at least one radio frequency channel in the unlicensed radio frequency band is available for offloading traffic, for network selection, for network re-selection, or for a supplemental connection via carrier aggregation based on the ANDSF policies, measured interference levels, and/or loading information provided by the eNodeB.

Abstract: Mobile devices, base stations, and/or relay stations may implement methods for decreasing required guard bands while also minimizing Adjacent Channel Leakage Ratio, when multiple mobile devices communicate over different respective adjacent specified frequency bands. For communications over at least one specified frequency band of the different respective adjacent frequency bands, a first bandwidth of uplink communications and/or a second bandwidth of downlink communications may be adjusted to differ from each other, and/or a communications bandwidth within the specified frequency band may be adjusted to be of a first size during a first portion of a specified data transmission period and to be of a second size during a second portion of the specified data transmission period, when at least some of the communications over the specified frequency band take place at frequencies adjacent to frequencies at which at least some of the communications take place over another specified frequency band.

Abstract: Apparatuses, systems, and methods for enhancement of network slicing for a UE. A UE may receive, from an AMF of a network, application related information associated with network slice data routing for data associated with an application. The information may be provided to the network by network slice customers. The UE may, in response to application initiation, determine traffic routing for data associated with the application. Traffic routing may be based on the application related information and a UE configuration associated with user privacy (e.g., user privacy setting) associated with the application. When the user UE configuration is enabled, the data may be routed via a default network slice and when the UE configuration is disabled, the data may be routed via a network slice indicated by the application related information. The UE configuration may be indicated by the application via a Boolean flag and/or via a user interface setting.

Abstract: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.
