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.

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 from a media server, that the UE is going to experience the coverage-throughput reduction and (ii) based at least in part on the predicting, proactively initiating transcoding of the streaming media to reduce a bit rate of the streaming media en route to the UE in a communication path between the media server and the UE, the initiating occurring before the UE experiences the coverage-throughput reduction so that the bit rate of the streaming media is reduced by when the UE experiences the coverage-throughput reduction.

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.

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.

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.

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.

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 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 applicable to control when to deconfigure the uplink SCell from service of the UE, with the dynamically setting of the channel-quality threshold including setting the channel-quality threshold to a value selected based on one or more operational circumstances of the UE, such as whether the UE is engaged in uplink heavy or rather uplink light communication. And the access node applies the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE.

Abstract: When a UE is served by a first radio access network (RAN) and is engaged in a voice call such as a VoIP call, a determination will be made that the UE is at an edge of coverage (e.g., threshold poor coverage) of the first RAN and that there is no other adjacent coverage of the first RAN that could support the voice call. In response, signaling will cause a second RAN to page the UE via the first RAN so as to cause the UE to transition from being served by the first RAN to being served by the second RAN. More generally, when a UE has poor coverage of its serving RAN, another RAN will pull the UE to the second RAN by paging the UE to trigger transition of the UE from to the second RAN.

Abstract: Methods and systems to help manage wireless communication with UEs in a manner that takes into account an extent of TTI bundling on a given carrier frequency. When a base station is serving a threshold high number of TTI-bundling-UEs on a first carrier frequency, the base station will reduce the number of TTI-bundling-UEs on the first carrier frequency by offloading one or more of the TTI-bundling-UEs from the first carrier frequency to a second carrier frequency. Further, to avoid increasing the number of TTI-bundling-UEs served on the first carrier frequency, when the base station detects a trigger event for enabling TTI bundling for an additional UE served on the first carrier frequency, the base station will offload the additional UE from the first carrier frequency to the second carrier frequency.
