Abstract: Methods, systems, and devices for wireless communications are described that provide for timing synchronization among one or more time sensitive network (TSN) endpoints via a wireless communications network. A data flow may be established via the wireless communications network, in which one or more system messages associated with the data flow may provide timing information for the data flow. A first node within the wireless communications network may receive a request for establishing such a data flow with a user equipment (UE). The first node may receive timing information for the data flow via one or more system messages associated with the data flow, and establish the data flow based at least in part on the timing information.

Abstract: Methods, systems, and devices for dynamic monitoring and scheduling in retransmission are described for wireless communications. For example, a receiving device may receive a data transmission in a first receiver bandwidth, determine that a data packet of the data transmission was unsuccessfully decoded, switch to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth (e.g., based on determining that the data packet was unsuccessfully decoded), and receive a retransmission of the data packet in the second receiver bandwidth. In another example, a transmitting device may schedule a data transmission according to a first receiver bandwidth, receive an indication that a data packet of the data transmission was unsuccessfully decoded, and schedule a retransmission of the data packet according to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth.

Abstract: Methods, systems, and devices are described for assessing the quality of end-to-end connectivity for a wireless communication device. Data generated from at least one of existing traffic and networking operations caused by existing traffic of the wireless communication device may be monitored to obtain information related to connectivity quality. One or more values of one or more metrics may be determined using the obtained information. The quality of end-to-end connectivity for the wireless communication device may be assessed using the value(s) of the metric(s). Based at least in part on a result of the assessment, an action may be performed to improve connectivity quality for the wireless communication.

Abstract: The disclosure describes methods and apparatuses for handover-related measurements and events for power adaptation. The disclosure provides for management of an eNodeB for improving reliability of incoming handovers to a cell provided by the eNodeB. At least one handover failure event for an incoming handover to a cell provided by the target eNodeB is detected. The eNodeB or central entity determines that the cell is providing an undesired coverage area based on the at least one handover failure event. In response to determining that the cell is providing an undesired coverage area, the transmit power for the cell may be adjusted to alter the undesired coverage area. A performance measurement based on the at least one handover failure event may be used to evaluate the undesired coverage area. The incoming handover failure events may include incoming too-early handovers, incoming too-late handovers, incoming wrong cell handovers, and incomplete incoming handovers.

Abstract: A method includes: establishing a telecommunication link between a device and a service provider system via a telecommunication network; receiving a device public key via the telecommunication network from the device at the service provider system, the device public key predating the establishment of the telecommunication link; verifying, at the service provider system, that the device stores a device private key in a secure storage area of the device, the device private key corresponding to the device public key, the device public key and the device private key being a cryptographic key pair; and authorizing, by the service provider system, sign-up of the device for service enrollment in response to verifying that the device stores the device private key in the secure storage area of the device.

Abstract: Resources are reserved for handover signaling. Handover reliability is thereby improved since the primary interference for handover signaling will be from the handover signaling of nearby cells (e.g., as opposed to data traffic). Given the relatively sparse nature of handover signaling, a significant reduction in interference may be achieved in a network employing this technique in comparison to conventional networks. In some implementations, a set of neighboring access points cooperate to determine which resources are reserved for handover signaling. In some implementations, resources for handover signaling are reserved on a network-wide basis or an access point cluster-wide basis.

Abstract: Detecting local cell identifier collision by a base station may be achieved by receiving, at a first base station from a user device, a dedicated identifier associated with a second base station. The dedicated identifier may include or otherwise map to a user device identifier associated with the second base station and a local cell identifier associated with the second base station. Based on the dedicated identifier, it may be determined, at the first base station, that there is a local cell identifier collision between the first base station and the second base station.

Abstract: A method for enhancing assignment of mobility classifications to mobile devices is described. A plurality of mobility classifications are stored in association with a plurality of mobile devices to indicate, for each mobile device, one or more handover parameters used by the mobile device. One or more handover parameters associated with the plurality of mobility classifications are updated based on mobility events. An error determination is made that one or more of the one or more mobile devices are incorrectly associated with the mobility classifications based on the one or more updated handover parameters for the plurality of mobility classifications. In response to the error determination, one or more new criteria are established that adjust how the mobility classifications are assigned.
