20120252455 | Fast Reselection Between Different Radio Access Technology Networks - A user equipment UE determines that a neighbor cell is higher priority than a serving cell, measures neighbor cell signal strength in n>1 iterations, and analyzes them for reselecting from the serving cell to the neighbor cell. Each measurement iteration is spaced from one another by a time interval (e.g., 1 DRX) that is specific for the neighbor cell being higher priority. In various embodiments, the UE measures while in a Cell-PCH, URA-PCH or idle state/mode and the first iteration is taken at the first available measurement opportunity after transitioning to that state/mode. The UE reselects to the neighbor cell based on the analyzed signal strengths; in one embodiment the decision to reselect is without regard to signal quality of the serving cell; and in another the decision is without regard to whether a reselection condition remains satisfied for a specified time period T | 10-04-2012 |

20140038609 | MEASUREMENT REPORTING - A network sends downlink a neighbor frequency list for redirection (with at least one neighbor frequency) for measurement, for example event-triggered measurement. For each frequency in the list which a user equipment UE finds to satisfy one or more criteria, for example event-triggering criteria, the idle-state or semi-idle-state UE then takes a measurement of the neighbor frequency and checks whether the measurement satisfies reporting criteria. The UE sends to its serving cell an indication of the neighbor frequency or frequencies whose measurement meets the reporting criteria, without reporting the measurement, such as in a RRC Connection Request message. The serving cell then redirects the UE to establish a connection on a target frequency selected from the indicated neighbor frequencies, and this redirect may be in a RRC Connection Reject message. | 02-06-2014 |

20140334319 | Methods, Apparatus and Computer Programs for Operating a Radio Access Network and User Equiptment - A user equipment (UE) is configured with a first configuration for reporting measurement feedback information according to a first reporting cycle using a first set of parameters, and a second configuration for reporting measurement feedback information according to a second reporting cycle using a second set of parameters. The UE switches between the first cycle and the second cycle for reporting for example CQI based on for example comparing a data or a channel measurement against a predefined threshold. In various embodiments the second configuration is fixed, or results in no CQI reporting, or is variable based on a previous cycle or CQI level, or is event-based. In another embodiment, the network commands the UE to switch. The end result is that control signalling overhead can be reduced when appropriate by reducing the number of CQI reports that are sent uplink. | 11-13-2014 |
