1. A method for positioning reference signal bandwidth adaptation, comprising:
determining a target user equipment (UE) positioning accuracy;
determining a positioning frequency layer and a positioning reference signal bandwidth based on the target UE positioning accuracy;
transmitting a positioning reference signal using the positioning frequency layer based on the positioning reference signal bandwidth;
detecting a change of status of the UE resulting in a lower target UE positioning accuracy; and
transmitting, to the UE based on the lower target UE positioning accuracy, a signal configured to enable the UE to reduce a positioning reference signal measurement bandwidth of the UE for the positioning frequency layer.
