Abstract: A method and system for managing time segments per subframe used for downlink control channel communication by adjacent base stations that each provide carrier-aggregation service on first and second component carriers. The base stations may work with each other to differentially structure the component carriers, such that the base stations use different time segments than each other for downlink control channel communication on the first component carrier but the same time segments as each other for downlink control channel communication on the second component carrier. Further, based on this differential structuring, the base stations may then schedule transmission of one type of data on the first component carrier and another type of data on the second component carrier.

Abstract: A radio access network (RAN) may be configured to manage paging of a wireless communication device (WCD). The RAN may initiate a paging process to page the WCD, and the paging process may comprise the RAN transmitting to the WCD a defined sequence of page attempts until the RAN receives a page response from the WCD or the RAN has transmitted a final page attempt of the sequence. After the RAN has transmitted at least one page attempt of the sequence but before the final page attempt of the sequence has been transmitted, the RAN may determine that the RAN has not received the page response from the WCD, and that the WCD is currently engaged in active data communication, and the RAN may responsively discontinue the paging process.

Abstract: A method and system that uses user-equipment (UE) capability reporting to control UE service. A UE provides its serving base station with an initial capabilities report indicating that the UE does not support determining and reporting when neighboring coverage is threshold strong, and so the base station does not yet provision the UE with a measurement event including a threshold to facilitate such determining and reporting. When the UE then determines that its serving coverage is threshold weak, the UE then transmits to its serving base station an updated capabilities report indicating that the UE does support such determining and reporting, and so the base station then provisions the UE with threshold (e.g., provisions the UE with a measurement event causing the UE to compare measured neighbor coverage strength with such a threshold).

Abstract: A serving base station (SBS) that provides service to a UE device can receive or determine admission capacity of a neighbor base station (NBS). The SBS can determine a reporting interval based on the admission capacity and provide the UE device with the reporting interval. Upon determining that handover from the SBS to the NBS may be necessary, the UE device can responsively start transmitting measurement data regarding the NBS to the SBS. Transmission of the measurement data can occur at intervals that equal the reporting interval. The value of the reporting interval can be conditioned on the admission capacity of the NBS. As the capacity for admitting more UE devices decreases, the likelihood of the UE device handing over to the NBS may decrease. Increasing the reporting interval for reporting measurement data regarding the NBS can reduce loading of the reverse-links to the SBS.

Abstract: A method and apparatus to help minimize tuneaway time of a user equipment device (UE), by dynamically scheduling when the UE should tune away to scan for coverage of a particular wireless communication system, such as a time division duplex (TDD) system for instance. The UE may receive downlink transmissions from a TDD system and determining a downlink transmission schedule of the TDD system based on when those downlink transmissions occurred. Further, the UE may then use the determined downlink transmission schedule as a basis to schedule tuneaway of the UE from a serving system to scan for coverage of the TDD system.

Abstract: A method and system for controlling handover of a WCD based on the WCD's operating temperature. In an example implementation, a determination is made that the WCD's operating temperature is threshold high, and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as to another carrier frequency or to another base station coverage area. Further, in another example implementation, a determination is made that the WCD's operating temperature is threshold low (e.g., is not threshold high), and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as back to the WCD's initially serving coverage system.

Abstract: Disclosed is a method and system to help manage handover of a UE based on data buffering. In accordance with the disclosure, when a base station receives data destined for a UE, the base station may record the received data into a data buffer for temporary storage and retrieve the data at some later time to transmit the data to the UE. The base station may then determine, based at least in part on an amount of elapsed time from recording the data to retrieving the data, whether to invoke handover of the UE from being served by the base station to being served by a different, neighboring base station.

Abstract: A method and system for setting a hold-timer duration is disclosed. The method involves a first network initially serving a user equipment device (UE), wherein serving the UE comprises allocating at least one resource to the UE and using the at least one resource to serve the UE. The method also involves detecting transition of the UE from being served by the first network to being served by a second network. The method further involves, after the UE transitions to the second network, applying a hold-timer having a hold-timer duration for release of the at least one resource. Further, the method involves, before setting the hold-timer duration, the first network receiving from the UE a report including an indication of radio frequency (RF) quality of the second network. The method also involves using the reported indication of RF quality as a basis to set the hold-timer duration.

Abstract: A method and corresponding system to help manage user equipment device (UE) transmission power, specifically in a scenario where the UE was being served by a base station on a first carrier frequency and the UE is then going to communicate with a base station (whether the same or another base station) instead on a second, different carrier frequency. As disclosed, a UE may determine, based on communication by the UE on the first carrier frequency, a baseline initial transmit power for the UE to use for an initial transmission from the UE to a cellular base station on the second carrier frequency. Responsive to the second carrier frequency being different than the first carrier frequency, the UE may adjust the baseline initial transmit power to establish an adjusted initial transmit power. The UE may then engage in the initial transmission using the adjusted baseline initial transmit power.
