Abstract
Systems and methods are disclosed to provide positioning enhancement to wireless systems to determine UE positioning using UE measurements. A method implemented by a UE for enabling positioning calculation includes receiving a Signal to Interference plus Noise Ratio (SINR) threshold from a network for filtering positioning measurements and performing a plurality of positioning measurements. The method also includes removing from the positioning measurements each measurement that does not meet the SINR threshold, and sending remaining positioning measurements that meet the SINR threshold to the network. Another method implemented by a network component includes receiving a plurality of positioning measurements with a plurality of corresponding SINRs from a user device and removing from the positioning measurements each measurement with a corresponding SINR that is less than or equal to a pre-determined SINR threshold. The remaining positioning measurements with corresponding SINRs greater than the SINR threshold are then used for positioning calculation.
