1. An apparatus in a communication system, comprising:
processing circuitry, configured to:
receive configuration parameters for a reference signal based on a level of phase noise for the reference signal estimated by a user equipment, the configuration parameters for the reference signal comprising a subcarrier spacing of the reference signal;
apply the configuration parameters to the reference signal to obtain a modified reference signal; and
transmit the modified reference signal to the user equipment to enable a position of the user equipment to be determined.
