20080311900 | CELL SELECTION - To determine a cell for usage in wireless communication, a signal-to-noise ratio or a signal-to-power ratio can be used in selecting an appropriate cell. However, cell selection can also configure to take both signal-to-noise ratio and signal-to-power ratio into account. Multiple available cells can be analyzed and a highest ranking cell can be selected through balancing the aforementioned ratios. In addition, to minimize transferring between cells, a limitation can be placed such that a cell is not left unless there is better of both the aforementioned ratios at another cell. | 12-18-2008 |

20120142328 | SYSTEM AND METHOD FOR ASSISTING IN POWERING ON SLEEPING NETWORK ENTITIES - Techniques are provided to facilitate offloading of mobile entities from a serving network entity. For example, there is provided a location-based method that involves, in response to a load of the requesting entity exceeding a load threshold, identifying candidate network entities to which to offload a user equipment (UE), each of the candidate network entities being in sleep mode. The method may involve determining coverage and location information for the candidate network entities, and determining location information for the UE. The method may involve selecting a given network entity to turn ON based at least in part on the coverage information and the location information. The method may involve sending an ON-request message to the at least one selected network entity, the ON-request message including a timer that can be used to deactivate the selected network entity in case it is not useful in offloading the serving network entity. | 06-07-2012 |

Handover request messages for a relay and related user equipment (UE) can be grouped to lessen signaling requirements for handover. Moreover, identifiers can be communicated in the messages to optimize bearer establishment at a target base station to which the relay and related devices are handed over. Also, handover exception cases can occur, which can be handled by the relay and source and target base stations, such as bearer rejection at the target base station, handover failure for one or more devices or the relay, and/or the like. Further, handover of a relay can occur between base stations that house one or more network gateways for the relay, or where the gateways are centralized and accessible by the source and target base stations, where each scenario can include different exception handling. | 10-04-2012 |
20120264416 | SELECTIVE STATE TRANSITIONS OF A USER EQUIPMENT WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a user equipment (UE) determines that a client application has entered a period of transmission inactivity whereby the UE will not be required to transmit data on behalf of the client application. The UE selectively transmits a transmission inactivity notification to an access network (AN) to notify the AN of the transmission inactivity period. The AN receives the transmission inactivity notification and determines to transition the UE from a first state to a second state based at least in part on the received transmission inactivity notification, the second state associated with lower-power consumption of the UE than the first state. The AN sends instructions to the UE to facilitate the transition of the UE from the first state to the second state. In another embodiment, the AN can send instructions to the UE to prohibit the UE from sending transmission inactivity notifications. | 10-18-2012 |
20130072123 | CHANNEL QUALITY REPORTING USING A DYNAMICALLY ADJUSTED MEASUREMENT POWER OFFSET - Methods and apparatuses are provided for facilitating dynamic measurement power offset adjustments for use in reporting channel quality feedback. A user equipment may generate and send a plurality of channel quality indicator (CQI) values to a base station.
