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 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.

Abstract: Given first and second base stations that have at least partially geographically-overlapping coverage on at least partially frequency-overlapping carriers, a determination could be made that the first base station supports voice-interworking service in which served UEs could separately receive voice-over-circuit service but that the second base station does not support voice-interworking service. And in response to at least that determination, the second base station could be given priority over the first base station for providing voice-over-packet service.

Abstract: When multiple user equipment devices (UEs) are served with dual connectivity, with each UE being served by a first access node on a respective first connection according to a first RAT and all of the UE's respective first connections having a first carrier as anchor carrier for the dual connectivity, the first access node will detect that load on the first carrier is threshold high. And in response, the first access node will (i) select one or more of the UEs based on each of the selected one or more UEs being within uplink range of the first access node on a second carrier higher in frequency than the first carrier and (ii) for each selected UE, reconfigure the UE's respective first connection from having the first carrier as the anchor carrier for the dual connectivity to instead having the second carrier as the anchor carrier for dual connectivity.

Abstract: When a UE is served with dual-connectivity service on a first radio access technology (RAT) concurrently with a second RAT, and when a serving base station faces a choice of which additional carrier to add to the UE's connection according to the first RAT for carrier-aggregation service of the UE according to the first RAT, the selection of an additional first-RAT carrier will be made based on a consideration of the carrier's load attributable to first-RAT-only service as compared with dual-connectivity service. For instance, the base station could select an additional first-RAT carrier based on the carrier's load attributable to first-RAT-only service, perhaps for high-priority first-RAT-only service, being threshold low. Or the base station could exclude from the selection a candidate first-RAT carrier based the carrier's load attributable to such first-RAT-only service being threshold high. The base station could then configure carrier-aggregation service of the UE accordingly.

Abstract: Methods and systems are provided for calculating a bias value based on radio frequency signal power measurements. A wireless communication device (WCD) measures the powers of radio frequency signals received by the WCD, including a first radio frequency signal transmitted by a first base station of a wireless network and a second radio frequency signal transmitted by a second base station of the wireless network. The first base station transmits radio frequency signals at a higher power than the second base station. The WCD calculates a bias value based on at least one of the measured powers of the first radio frequency signal and the second radio frequency signal. The bias value, in combination with the measured powers of the first and second radio frequency signals, can be used to select one of the first and second base stations.

Abstract: According to aspects of the present disclosure, a method and system are provided for wireless communication between a user equipment device (UE) and a base station using carrier aggregation and transmission time internal (TTI) bundling. The base station serves the UE with carrier aggregation on multiple carriers and determines, per carrier, a respective bundling size for transmitting a wireless communication between the UE and the base station with transmission TTI bundling on that component carrier. The determined bundling size for at least one of the plurality of component carriers is different than the determined bundling size for another one of the plurality of component carriers. While serving the UE with carrier aggregation on the multiple carriers, the base station invokes TTI bundling to transmit the wireless communication between the UE and the base station on each carrier with the respectively determined bundling size for that component carrier.

Abstract: Example methods and an example controller for controlling a bit rate at which a media server streams media content to a UE are provided. The example controller includes at least one processing unit and data storage having instructions executable by the processing unit to carry out operations. The operations include determining an extent to which the UE is configured to tune away from a first RAN to a second RAN to check for pages. Further, the operations include, based on the determined extent, (i) establishing the bit rate and (ii) causing the media server to stream the media content to the UE at the established bit rate.

Abstract: A method and system for dynamically controlling transition of a UE between operating modes based on a consideration of air interface congestion and interruption-sensitivity of communication. The UE operates by default in a first mode such as a circuit-switched-fallback (CSFB) mode. While so operating, a determination is made that the UE's serving air interface is threshold highly congested. In response, if the UE is not engaged in interruption-sensitive communication, the UE then transitions from operating in the first mode to operating in a second mode such as a non-CSFB mode (e.g., a single-radio LTE (SRLTE) mode).
