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: 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: 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 method for configuring a first base station to use a coverage area identifier is described. For instance, a computing system may determine that coverage provided by the first base station overlaps with coverage provided by a second base station. Further, of a plurality of third base stations that also provide coverage overlapping the coverage provided by the second base station, the computing system may identify one or more third base stations having an extent of handover with the determined second base station that is below a threshold extent of handover. The computing system may then select, as the coverage area identifier to be assigned to the first base station, a coverage area identifier that is also assigned to a particular one of the one or more identified third base stations. The computing system may configure the first base station to use the selected coverage area identifier.

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: Embodiments are described that may help to provide wireless service in a circuit-switched fall back scenario. In particular, when a user entity (UE) falls back from a first network to a second network to conduct a voice call, the first network may instruct the UE to scan a certain predetermined channel or channels for coverage from the second network. However, certain types of base stations typically operate on unlisted channels that differ from the predetermined channels that the UE is instructed to scan. Accordingly, a UE may pre-emptively scan unlisted channels, and report any unlisted channel that is detected to the first network. The first network can then coordinate with the second network to re-provision the base station that was operating on an unlisted channel, to instead operate on one of the predetermined channels that a UE will be instructed to scan during fall back to the second network.

Abstract: Disclosed is a method and system for dynamically managing carrier aggregation based on operating conditions of small cells in a wireless communication system. A first base station may be configured for providing wireless services on a first wireless carrier band and a second wireless carrier band. One or more additional base stations may each configured for providing wireless services on the second wireless carrier band. A determination can be made that a load on the one or more additional base stations exceeds a threshold level while each is providing wireless coverage within a region that at least partially overlaps with wireless coverage provided by the first base station. In response, the first base can be caused to refrain from aggregating the first and second wireless carrier bands for providing wireless services under operational conditions defined to cause the base station to aggregate the first and second wireless carrier bands.
