    摘要： 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. The base station determines whether at least some of the received CQI values are outside of an upper or lower threshold value. If at least some of the received CQI values are outside the upper or lower threshold value, the base station can transmit an adjusted measurement power offset to the user equipment. On receipt of the adjusted measurement power offset, the user equipment generates subsequent CQI values using the adjusted measurement power offset.

    摘要： Methods, devices, processors and computer program products for mobile terminal-based Radio Resource Management (RRM) and network optimization. The mobile terminal measures or otherwise obtains radio condition measurements (such as received power, interference, mobile transmit power and the like) and/or geographical location measurements. The radio condition measurements and/or location measurements are compared against historical data and/or target Key Performance Indicators (KPI) and, based on the comparison, a determination can be made as to whether adjustment of RRM parameters is warranted. By providing for RRM management at the mobile terminal level, as opposed to a cell or Radio Network Controller (RNC) level, better granularity of management is realized in the overall radio network. Further, individual mobile terminals can better tailor their radio resource needs to meet their conditions of use and, as such, better overall service can be realized by the individual mobile terminals in the network.

    摘要： Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.
