Abstract: Methods and systems for determining how much time a user equipment (UE) device should spend scanning for base station signals and how often the UE device should provide reports to a position determining equipment (PDE) device regarding the scanned base station signals so as to determine an accurate position of the UE device, especially while the UE device is in motion or within areas of low base station density, are described. Selecting the rate to scan base station signals for a given frequency band can be based, at least in part, on the availability of the given frequency band in proximity to the UE device and to a throughput value associated with an application executing on the UE device. Selecting the rate to provide scanning reports can be based, at least in part, on a speed of the UE device and a network topology, such as base station density.

Abstract: A method and system for managing carriers on which a base station provides service to a user equipment device (UE), based on consideration of latency. A base station that is arranged to operate on a plurality of carriers may, while serving a UE on a set of one or more carriers of the plurality, select, from at least two other carriers of the plurality, an additional carrier to add to the set of one or more carriers on which the base station serves the UE, and may make the selection based a latency on the selected carrier. In response to selecting the additional carrier, the base station may add the selected carrier to the set of one or more carriers on which the base station serves the UE, and may then serve the UE on the set of one or more carriers including the selected carrier.

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).

Abstract: A method and system for controlling which of a plurality of base stations will serve a WCD. Per the disclosure, a base station is selected from the plurality based at least on an extent to which the selected base station can provide MU-MIMO service efficiently to the WCDs that the selected base station is serving. Thus, the base station that will serve the WCD could be selected for effectively serving a lower quantity of WCDs (if MU-MIMO service is enabled) than other base stations of the plurality. And the WCD could then receive service from the selected base station.

Abstract: Disclosed are a methods and systems for selecting a carrier aggregation approach. In particular, a wireless communication system includes a base station configured to serve a UE with carrier aggregation service on a TDD carrier and an FDD carrier. Accordingly, the system determines a type of content that will be transmitted between the base station and the UE and, based on the type of content, the system selects an approach for serving the UE with the carrier aggregation service. This selection is between the base station (i) carrying out uplink communication using only the TDD carrier and carrying out downlink communication using only the FDD carrier and (ii) carrying out downlink communication using only the TDD carrier and carrying out uplink communication using only the FDD carrier. Based on the selecting, the system configures the base station to serve the UE with the carrier aggregation service using the selected approach.

Abstract: In accordance with the disclosed methods and systems, while providing a service that enables user equipment devices (UEs) being served by a first network to engage in signaling with a second network via the first network, a controller or other network entity may detect a failure of paging in the first network. In response to detecting the failure of paging, the first network may then cause one or more UEs being served by the first network to transition from operating in a first mode that uses the given service to operating in a second mode that does not use the given service.

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.
