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: Disclosed herein is a method and system for controlling base station buffering of data. In an example method, the base station serves a wireless communication device (WCD) over an air interface, where the air interface encompasses a quantity of channels on which the base station serves the WCD, where the base station is configured to buffer, in a data buffer, data awaiting transmission to the WCD, where the buffer has a fullness-threshold defining a maximum quantity of data that the base station will buffer for the WCD, and where the base station is configured to respond to the quantity of data in the buffer meeting the fullness-threshold by increasing the quantity of channels. Then, while serving the WCD, the base station determines an extent to which the WCD provides connectivity between at least one other device and the base station, and sets and applies the fullness-threshold based on the extent.

Abstract: Disclosed herein are methods and systems for dynamically controlling bearer quality-of-service (QoS) configuration. In an example arrangement, a wireless communication device (WCD) may have a first bearer and a second bearer with a base station, where the first bearer has a first set of one or more QoS parameters defining a first priority level for the base station scheduling communications on the first bearer, and the second bearer has a second set of one or more QoS parameters defining a second priority level for the base station scheduling communications on the second bearer, the second priority level being different from the first priority level. In this arrangement, an example method may involve detecting that the base station is threshold highly loaded, and responsive to the detecting, reconfiguring the second bearer to have the same QoS parameters as the first set of one or more QoS parameters.

Abstract: According to aspects of the disclosure, a method and system are provided for managing signaling in a wireless communication network. In accordance with the disclosure, a base station serves a plurality of user equipment devices (UEs) via an air interface extending between the base station and the UEs. The base station also receives, on an uplink of the air interface, a report from each UE indicating channel state information (CSI). The base station periodically receives the report from each UE according to a CSI reporting rate specified by the base station for the UE. The base station may determine that a level of loading on the uplink is greater than a threshold load value. Responsive to such determination, the base station selects a subset of the plurality of UEs and reduces the CSI reporting rate for the selected subset of the plurality of UEs to reduce congestion on the uplink.

Abstract: Carrier aggregation may occur in wireless networks when multiple carriers from either contiguous frequency bands or non-contiguous frequency bands are aggregated together as component carriers. Wireless computing devices (WCDs) may use these aggregated component carriers as a single, logical channel for wireless communication. Such a WCD may determine that an amount of carrier aggregation used by a wireless interface of the WCD has increased. The WCD may receive data packets from a correspondent device by way of the wireless interface, and the WCD may transmit, in response to receiving the data packets, acknowledgment packets to the correspondent device by way of the wireless interface. Possibly based on the amount of carrier aggregation increasing, the WCD may reduce an extent of the acknowledgment packets transmitted to the correspondent device.

Abstract: A radio access network (RAN) may determine that a quality-of-service (QOS) load of a first base station exceeds a QOS load high threshold. The RAN may further determine that a set of wireless communication devices (WCDs) served by the first base station are located within a geographic area nearby a second base station. The RAN may additionally determine that the set of WCDs are responsible for at least a predefined portion of the QOS load of the first base station, and may power on the second base station. If at some point a second QOS load of the second base station falls below a QOS load low threshold, the RAN may facilitate handover of at least one of the WCDs served by the second base station from the second base station to the first base station, and may power off the second base station.

Abstract: Disclosed are methods and systems to facilitate selection of a donor base station to serve a relay node (RN). In particular, a base station system (BSS) may include a plurality of base stations each operable to serve user equipment devices (UEs) and operable to serve an RN. The RN is in turn operable to serve UEs. According to the disclosure, a controlling entity may determine both (i) a type of content communicated between the BSS and UEs served by the BSS (BSS-served content type) and (ii) a type of content communicated between the RN and UEs served by the RN (RN-served content type). Based on both the determined BSS-served content type and the determined RN-served content type, the controlling entity may select one of the plurality of base stations to serve the RN and may cause the selected base station to serve the RN.
