20130013797 | Extended Proximity Indication For Private Cells - A user equipment UE stores a first list of private cells to which the apparatus is authorized to access (e.g., a CSG whitelist). While under control of a serving first cell, the UE determines from a transmission received from a neighbor second cell a physical cell identity PCI of the neighbor cell, then compares the determined PCI to a stored second list to determine whether the UE is authorized to access the neighbor cell.

20130045770 | Coordination of DRX and eICIC - An active reception period (active time) of a power saving pattern (DRX) is masked to a measurement period (ABS) of a serving or neighbor cell interference mitigation pattern (eICIC) such that the masked active reception period repeatedly coincides with the measurement period. Then the masked active reception period is utilized for communicating resource allocations (PDCCHs) between a serving cell (eNB) and a user equipment (UE). In various embodiments: the masking is done without shortening a sleep opportunity (DRX opportunity) of the power saving pattern; the masking is implemented by delaying an on-duration start time of the active reception period; the on-duration start time is controlled by a timer which runs only during measurement periods of the interference mitigation pattern, or by applying a second offset generated by the UE in addition to applying a first offset configured by the serving cell; and the masking is by adopting a default power saving pattern. | 02-21-2013 |

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 |

A UE may receive from a wireless network an aperiodic measurement request to measure a special measurement object (e.g., a neighbor cell) specified in the aperiodic measurement request, e.g., in an unlicensed band. In response to the aperiodic measurement request, the UE may perform the measurement of the special management object until a further instruction from the wireless network or for a determined period of time. Inter-frequency measurements may be performed during the measurement gap determined from the aperiodic measurement request. | 10-09-2014 |
