1. A method for positioning reference signal configuration, comprising:
receiving, from a network node, one or more first positioning reference signals (PRSs) in a first PRS configuration;
performing one or more first measurements on the one or more first PRSs to determine one or more first characteristics of the one or more first PRSs;
sending, to the network node, a second PRS configuration comprising one or more second PRSs determined based on the one or more first characteristics of the one or more first PRSs;
receiving, from the network node, a third PRS configuration, wherein the third PRS configuration comprises one or more third PRSs having at least one different signal characteristic than the one or more first characteristics of the first PRS; and
performing one or more second measurements on the one or more third PRSs.
