Abstract:
A disclosed method includes receiving a time-of-arrival range filter configuration and a reference signal physical transmission time from a network node at a reference signal physical reception time. The time-of-arrival range filter configuration includes at least one of a time-of-arrival filter status, a time-of-arrival filter distance range, and a time-of-arrival configuration. A time difference between the reference signal physical reception time and the reference signal physical transmission time is determined, and a distance to the network node based on the time difference is calculated. Whether the distance is within the time-of-arrival filter distance range is determined, and the time-of-arrival filter status is determined. Based on the time-of-arrival filter status, actions are performed in accordance with the time-of-arrival configuration applicable for the distance.
