Abstract: A method for redirecting a user equipment (UE) from a first network to a second network is described. The method includes determining, at a wireless access point of the first network, information for the UE about one or more mobile network operator (MNO) networks. The method also includes selecting the second network for redirection from among the one or more MNO networks based on the determined information. The method further includes sending the UE a redirection message that redirects the UE from the first network to the second network.

Abstract: Methods, systems, and devices for wireless communications are described. An access node may schedule traffic with different levels of priority for communications with a user equipment. The access node may receive a time-sensitive networking time-aware schedule from a first interface via an Ethernet frame that defines a set of periodic time intervals reserved for transmitting traffic with a high-priority (e.g., hard-real time traffic). In some cases, one or more frequency resources may additionally be reserved for the high-priority traffic. Accordingly, during the reserved time intervals, if the high-priority traffic is present, the access node may transmit the high-priority traffic on the reserved frequency resource(s). Outside the reserved time intervals, the access node may schedule lower-priority traffic on the reserved frequency resource(s) in addition to the other resources. Alternatively, high-priority traffic may interrupt previously scheduled lower-priority traffic during the reserved time intervals if high-priority traffic is present.

Abstract: Methods, systems, and devices for wireless communications are described. A first node (e.g., a user equipment (UE)) may receive a timing synchronization signal from a second node (e.g., a base station) over a cellular wireless communication link. In some aspects, the timing synchronization signal may indicate mapping information to synchronize the first node with the second node. The mapping information may be for synchronizing a first time of a first clock of the first node to a second time of a second clock of a second node. The first node may synchronize the first time of the first clock to the second time of the second clock based at least in part on the mapping information and the synchronization information. The first node may transmit a timing control based on a timing of the second clock to a device connected to the first node via a local wired interface.

Abstract: Techniques are described for handover decisions based on an absolute channel quality of a serving cell. For example, there is provided a method that involves generating a set of handover parameters based on a report of serving cell signal quality to avoid ping-ponging effects of an access terminal between a serving cell and another cell. A network entity receives a report regarding a serving cell signal quality from a reporting entity. A set of parameters is defined for a network event and sent to an access terminal, where the set of parameters is based at least in part on the received report. The set of parameters for the network event is sent to the access terminal.

Abstract: The present disclosure presents a method and an apparatus for hybrid management of handovers in a self organizing network. For example, the disclosure presents a method for transmitting, via a transmitting component at the base station, handover signaling data from the base station to a network entity, wherein the base station is one of a plurality of base stations transmitting handover signaling data to the network entity, receiving, at the base station, feedback associated with one or more handover parameters of the base station, wherein the feedback is received from the network entity and includes an indication of an amount of handover signaling data generated by the base station or the plurality of base stations, and updating the one or more handover parameters based on the feedback received and local information available at the base station. As such, hybrid management of handover in a self organizing network may be achieved.

Abstract: Various features pertain to the authentication of mobile devices or other User Equipment. In some aspects, a Retail-based Neutral Host LTE is provided for use with Long Term Evolution (LTE) networks that, among other features, provides a WiFi Alliance HotSpot 2.0 (HS2.0) user experience using LTE technology for non-mobile network operator (non-MNO) Service Providers (SPs), while maintaining high security assurances as with LTE. That is, in some examples, Retail Neutral Host-LTE is configured to provide the same or similar security assurances as with MNO-based LTE. Moreover, retail Neutral Host-LTE offers options for provisioning credentials and authentication with the AAA that are analogous to the options for HS2.0, that is: username/password, SP-issued certificate, and pre-configured mobile device certificate. This is achieved, at least in part, while providing or ensuring that Retail Neutral Host-LTE security provides similar security assurances to MNO-based LTE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may attempt to access a network at a local area network access point without prior context information. The access point may be a hotspot operating in unlicensed spectrum according to a Long Term Evolution (LTE)-based standard. The UE may be unable to determine if it is authorized to access the network, so the UE may attempt to obtain system information that provides a list of service providers supported by the network. The UE may then determine whether it has credentials for a supported service provider, and the UE may access the network using those credentials when a supported service provider is recognized. Other broadcast messages may provide information about system information for supported service providers. A UE that is unable to access the network using stored credentials may attempt access using a random access channel procedure.

Abstract: Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

Abstract: The subject technology provides for initiating a communication interface in a wireless communication system. In an embodiment, a neighbor node is discovered at an access point. The subject technology receives, via a network message in response to discovering the neighbor node, an address indication associated with the neighbor node for configuration of the communication interface. It is then determined whether to initiate one of a direct communication interface or indirect communication interface for communication with the neighbor node based on the address indication in the received network message.

Abstract: Described herein are techniques for radio technology selection and power calibration in multi-RAT small cells. For example, the technique may involve determining, at an access point, path loss information for a circuit switched fallback failure location. The technique may involve building a path loss database over a time period from the path loss information and managing power or operation mode of a first RAT and a second RAT of the access point based on the path loss database.
