摘要： 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.

摘要： 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).

摘要： 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.

摘要： 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.

An embodiment takes the form of a method of operating a wireless network system that includes a first base station operating on a first frequency and one or more second base stations operating on a plurality of second frequencies.

The frequency-hopping pilot beacon may prioritize transmission on particular frequencies according to usage of one or more particular applications by mobile devices served by the femtocell. The femtocell and/or femtocell control elements in the macro-network may determine that one or more particular applications are used by mobile devices served by the femtocell, identify one or more frequencies associated with the one or more frequencies, and then cause the femtocell to prioritize transmission on the identified one or more frequencies as compared to other frequencies.

摘要： Disclosed herein is a method and corresponding apparatus to help manage wireless communication between a base station and a device served by the base. In accordance with the disclosure, when a base station transitions from serving the device on just a first carrier to serving the device on a combination of the first carrier and a second carrier, the base station will responsively take action to improve downlink communication to the device on the first carrier. In particular, the base station will respond to the occurrence of that transition by starting to beamform downlink transmission to the device on the first carrier.

摘要： In a long term evolution (LTE) network, coordinated multipoint (CoMP) and transmission time interval (TTI) bundling can both help to improve uplink communications, but both can also place a burden on network resource. Further, since both utilize redundancy to improve uplink communications, albeit in different ways, use of CoMP and TTI bundling may be considered unnecessary. Accordingly, example methods and systems are provided that may help to balance the application of TTI bundling and CoMP.
