Abstract
Techniques for using measurements made by UEs to improve network performance are described. In one aspect, RF parameters of cells may be determined by taking into account mobility of the UEs. Mobility information for the UEs may be determined based on measurement report messages (MRMs) sent by these UEs for handover. RF parameters such as antenna down-tilt, antenna orientation, antenna pattern, and/or pilot power of the cells may be determined based on the mobility information for the UEs. In another aspect, the RF parameters of cells may be dynamically adjusted based on loading conditions of cells. In yet another aspect, the location of a UE may be determined based on an MRM sent by the UE for handover. The MRM may include timing measurements for multiple cells. The location of the UE may be determined based on the timing measurements.
