  • Patent number: 11523320
    Abstract: A method and system for controlling transmission of signaling between a first access node and a second access node, in a system where the first access node and second access node are each configured to provide respective wireless coverage and service. An example method includes monitoring a total volume of data communication between the first access node and the second access node and, based at least on the monitoring, controlling a rate of periodic control signaling between the first access node and the second access node. In a dual-connectivity implementation, the method could apply, for instance, to control a rate at which the second access node transmits data-usage reports (e.g., second-RAT usage reports) to the first access node.

  • Patent number: 11516863
    Abstract: A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing a level of fading of the first air-interface connection with a level of fading of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

  • Patent number: 11516815
    Abstract: Methods and systems are provided for dynamically capping an MCS index. A determination that one or more user devices are serviced by a sector of a cell site that has a Sector Power Ratio (SPR) above a threshold is made. Based on the SPR being above the threshold, the MCS index of the one or more user devices is capped. In response to the capped MCS index, a first Quadrature Amplitude Modulation (QAM) value is assigned to at least one of the one or more user devices based on a triangulation area corresponding to a location of the at least one of the one or more user devices.

  • Patent number: 11503522
    Abstract: A source access node that is configured to hand over a wireless User Equipment (UE) to a target access node. A radio wirelessly receives a measurement report from the UE that characterizes signal strength for the target access node, the signal strength for the source access node, and UE capabilities for the UE. Baseband circuitry determines to hand over the UE to the target access node based on the measurement report. The baseband circuitry receives UE load information from the target access node that indicates UE loads for the frequency bands of the target access node. The baseband circuitry determines UE capabilities for the overloaded frequency bands. The baseband circuitry transfers handover instructions to the UE that direct the UE to remove UE capabilities for the overloaded frequency bands. The UE updates the UE capabilities list and hands over to a non-overloaded frequency band of the target access node.

  • Patent number: 11490301
    Abstract: Methods and systems for preventing or delaying handovers to target access nodes that are experiencing intermodulation distortion. Ensuring service quality in dual-connectivity (EN-DC) wireless networks includes determining that a target access node for a handover of a wireless device is experiencing an intermodulation distortion level that exceeds a first threshold, and adjusting handover thresholds to delay the handover of the wireless device to the target access node. If the handover is necessary, dual-connectivity is disabled for the wireless device.

  • Publication number: 20220345181
    Abstract: Methods, media, and systems are provided for restricting an uplink Multiple Input Multiple Output (MIMO) assignment based on fading, battery data, or location data associated with a user device in an mmWave system. Fading data, location data, or battery data is received from one or more user devices. Based on the received data, a determination is made using the data received (e.g., determining the battery data of the user device is below a threshold or determining the location of the user device). In response, the assignment of the user device to an uplink MIMO layer of available MIMO layers is restricted. The restricted uplink MIMO layer is a higher MIMO layer than another MIMO layer of the available MIMO layers. In response to restricting the assignment, the user device may be assigned to an available MIMO layer that is a lower MIMO layer than the restricted MIMO layer.

  • Publication number: 20220338296
    Abstract: A wireless User Equipment (UE) controls a wireless network slice type that has slice requirements. In the UE, source Radio Resource Control (RRC) circuitry exchanges source signaling with a source Access and Mobility Management Function (AMF). During the exchange of the source signaling, target RRC circuitry exchanges target signaling with target AMFs and determines AMF characteristics. The target RRC circuitry compares the AMF characteristics to the slice requirements and selects one of the target AMFs based on the comparison. The source or target RRC circuitry exchange additional target signaling with the selected one of the target AMFs to use the wireless network slice type. User-plane circuitry exchanges user data with the wireless network slice which is controlled by the selected target AMF.

An example method includes selecting one of the frequency segments of the frequency bandwidth of the wideband carrier on which to define the narrowband carrier, with the selecting being based on the one frequency segment having a lowest level of noise among the plurality of frequency segments. And the example method may then further include, based on the selecting, configuring the narrowband carrier on the selected frequency segment of the frequency bandwidth of the wideband carrier rather than on another frequency segment of the plurality of frequency segments.

  • Patent number: 11464077
    Abstract: A wireless communication network serves a wireless User Equipment (UE) and comprises a wireless access node and a support access node. The wireless access node determines packet drop rate for the support access node. The wireless access node determines an add threshold for the support access node based on the packet drop rate for the support access node. The wireless access node determines an add value for the support access node and determines when the add value is greater than the add threshold. When the add value is greater than the add threshold, the wireless access node signals the support access node to serve the wireless UE and signals the wireless UE to attach to the support access node. In response, the support access node wirelessly transfers user data for a wireless communication service to the wireless UE.
