Abstract: Dynamic reconfiguring of dual-connectivity service of a UE includes detecting that quality of the UE's second air-interface connection with a second access node is threshold poor and responsively reconfiguring the dual-connectivity service from (i) a first mode in which user plane communication of the dual-connectivity service is downlink on both the first and second air-interface connections and is uplink on the second air-interface connection but not on the first air-interface connection to (ii) a second mode in which the user-plane communication of the dual-connectivity service is downlink on both the first and second air-interface connections and is uplink on the first air-interface connection but not on the second air-interface connection.

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 mechanism 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 system 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 first access node blocks dual-connectivity-capable UEs from being connected with the first access node while allowing UEs that are not dual-connectivity capable to be connected with the first access node.

Abstract: A method and system for controlling air-interface resources on a radio-frequency (RF) carrier on which an access node provides wireless communication service. While the access node is set to apply at least two resource-reservations (e.g., PRB-reservations) that are mutually exclusive on the carrier, a computing system detects that resource-availability on the carrier is threshold low. And in response to the detecting, the computing system causes the access node to combine together the at least two resource-reservations on the carrier The combining together of the at least two resource-reservations on the carrier retains the at least two resource-reservations on the carrier but results in a reduction in aggregate total quantity of air-interface resources consumed by the at least two resource-reservations on the carrier.

Abstract: A method and system for controlling wireless transmission to a user equipment device (UE) while the UE is served on a plurality of carriers each having a respective downlink bandwidth. An example method includes determining that a first carrier of the plurality of carriers has a wider downlink bandwidth than a second carrier of the plurality of carriers. And the method then includes, based at least on the determining, causing transmission to the UE on the first carrier to use a greater quantity of multiple-input-multiple-output (MIMO) layers than transmission to the UE on the second carrier.

Abstract: A method and system for controlling configuration of dual-connectivity service for a user equipment device (UE), where the dual-connectivity service would involve the UE being served concurrently by a first access node over a first connection according to a first radio access technology (RAT) and by a second access node over a second connection according to a second RAT. An example method includes selecting the second access node to be used in the dual-connectivity service of the UE, with the selecting being based cooperatively on (i) a power class of the UE and (ii) a quantity of receive antennas of the second access node. And the example method further includes, based on the selecting, configuring the dual-connectivity service for the UE.

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: A mechanism for controlling configuration of secondary-connectivity for dual connectivity service in a system including a first access node and a second access node. The first access node or another entity detects occurrence of a threshold extent of secondary-connection addition failures involving the second access node, each secondary-connection addition failure comprising failure of a respective attempt to set up secondary air-interface connectivity between a user equipment device (UE) and the second access node for use in dual-connectivity service of the UE. And responsive to at least the detecting, a measurement threshold that the first access node will impose for use in UE evaluation of coverage of the second access node for dual-connectivity setup is dynamically increased from a first coverage-strength value to a stronger second coverage-strength value so as to require stronger coverage of the second access node as a condition for adding secondary-connectivity with the second access node.

Abstract: When a first base station is serving a UE with carrier-aggregation on a combination of carriers including a first carrier as PCC of the carrier-aggregation service and a second carrier as an SCC of the carrier-aggregation service, the first base station could predict that the UE will hand over from being connected with the first base station to being connected with an adjacent second base station on the second carrier. In response to this prediction, the first base station could then reconfigure the UE's carrier aggregation service by swapping the UE's PCC and SCC so that the second carrier would become the PCC of the carrier-aggregation service and the first carrier would become an SCC of the carrier-aggregation service. This reconfiguration of the UE's carrier-aggregation service could thereby facilitate carrier continuity as the UE engages in the predicted handover.

Abstract: When a first node is considering setup of dual-connectivity service for a UE, the first node will take into consideration an uplink power headroom level of one or more candidate second nodes (representing uplink power headroom of one or more UEs served by such a node), in order to decide whether to set up the dual-connectivity service for the UE and/or to decide which of multiple second nodes to use for the UE's dual-connectivity service. For instance, if a candidate second node has a threshold high uplink power headroom level, then, based on that fact, the first node may decide to not use that second node for dual-connectivity service of the UE. Or the first node may decide to use a given candidate second node based on the given candidate second node having a higher uplink power headroom level than one or more other candidate second nodes.
