  • Patent number: 11863497
    Abstract: A method and system for controlling application of TTI bundling on a carrier on which an access node provides service, the carrier defining air-interface resources. An example method includes detecting that at least a predefined threshold number of devices of a predefined class (e.g., IoT devices) are connected with the access node on the carrier. Further, the example method includes, responsive to the detecting that at least the predefined threshold number of devices of the predefined class are connected with the access node on the carrier, proactively reserving a portion of the air-interface resources for use to serve communications between the access node and the devices of the predefined class and, in view of the proactive reserving of the portion of the air-interface resources, imposing a reduction in the application of the TTI bundling by the access node on the carrier.

  • Patent number: 11843433
    Abstract: A base station or an associated control entity determines when base station's air interface is threshold highly loaded or is predicted to be threshold highly loaded, and the base station responsively reduces the number of transmit antennas that the base station uses. Further, the base station or associated control entity could determine when the base station's air interface is no longer actually or predicted to be threshold highly loaded, and the base station could responsively increase the number of transmit antennas that the base station uses, such as by reverting to use a default number of antennas. Reducing the number of transmit antennas that the base station uses when its air interface is threshold highly loaded may help to increase air-interface capacity by reducing resource consumption from transmission of reference signals associated with the transmit antennas.

  • Patent number: 11818743
    Abstract: A method and system for controlling wireless service of a user equipment device (UE) by an access node. The access node serves the UE with uplink carrier-aggregation over a connection that encompasses encompassing multiple uplink channels including a primary uplink channel (uplink PCell) and a secondary uplink channel (uplink SCell). Further, the access node dynamically sets a channel-quality threshold (e.g., an RSRP threshold) applicable to control when to deconfigure the uplink SCell from service of the UE, with the dynamically setting of the channel-quality threshold including iteratively adjusting the channel-quality threshold based on uplink spectral efficiency of the access node. And the access node applies the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE.

  • Patent number: 11700554
    Abstract: A method and system for controlling air-interface connectivity of a user equipment device (UE). A computing system detects, when the UE has dual connectivity including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and when the first air-interface connection is defined on a first carrier, that the UE is moving toward a geographic area where UEs that were served by the first access node on the first carrier as part of dual connectivity lost their dual connectivity due to their having insufficient aggregate dual-connectivity throughput. And based at least on the detecting, the computing system reconfigures the first air-interface connection of the UE's dual connectivity to be defined on a lower-frequency second carrier, to help avoid having the UE lose its dual connectivity.

  • Patent number: 11611892
    Abstract: A method and system for controlling operation of a first access node that supports operation according to a first radio access technology (RAT) but does not support dual-connectivity operation according to the first RAT and a second RAT. A controller detects a high extent of occurrences of dual-connectivity-capable user equipment devices (UEs) being connected with the first access node when the dual-connectivity-capable UEs could instead connect with a second access node that supports the dual-connectivity operation. And in response, the controller suppresses coverage of the first access node, such as by reducing a maximum signal delay that the first access node applies for determining whether to accept random-access requests from UEs and/or (ii) reducing reference-signal transmission power of the first access node.

  • Patent number: 11457382
    Abstract: A method and system for proactively reconfiguring communication to a user equipment device (UE) in anticipation the UE experiencing a coverage-throughput reduction when the UE is receiving streaming media. An example method includes (i) predicting, when the UE is receiving streaming media, that the UE is going to experience the coverage-throughput reduction and (ii) based at least in part on the predicting, proactively increasing a quality-of-service (QoS) level of a bearer through which the UE is receiving the streaming media, the proactively increasing occurring before the UE experiences the coverage-throughput reduction so that the QoS level is increased by when the UE experiences the coverage-throughput reduction.

  • Patent number: 11419172
    Abstract: When a user equipment device (UE) is served with standalone connectivity by a first access node on a first carrier, the first access node could detect a trigger for transitioning the UE from the standalone connectivity to dual connectivity. In response to at least the trigger, the first access node could then (i) transition the UE from the first carrier to a second carrier selected based on the second carrier being lower in frequency than the first carrier, so as to help facilitate quality communication in the dual connectivity service, and then (ii) transition the UE from the standalone connectivity to the dual connectivity.

  • Patent number: 11026212
    Abstract: A method and system for controlling wireless connectivity between a user equipment device (UE) and an access node, where the access node supports operation on an FDD carrier and a TDD carrier, where FDD carrier has an uplink bandwidth, and where the TDD carrier has an effective uplink bandwidth that is defined based on an actual bandwidth of the TDD carrier limited by how often the TDD carrier is uplink (e.g., per a frame configuration). A method includes detecting, when the UE is connected with the access node on the TDD carrier, that the UE will engage in a threshold great extent of uplink data communication to the access node and, responsive to at least the detecting, reconfiguring the UE's connection by replacing the TDD carrier with the FDD carrier, based on the uplink bandwidth of the FDD carrier being greater than the effective uplink bandwidth of the TDD carrier.
