Claim 14:
15. The method of claim 13, further comprising:
determining whether the second time period is more than a second threshold; and
in response to a determination that the second time period is less than or equal to the second threshold, transmitting, by the target base station, a third ultrasound signal after a third time interval from the first time point; and
in response to a determination that the second time period is more than the second threshold, transmitting, by the target base station, the third ultrasound signal after a fourth time interval from a second time point when the target base station receives the second RF signal,
wherein
the third time interval is determined based on a count of base stations in a predetermined range and the first threshold,
the fourth time interval is determined based on the third time interval, the count of base stations in the predetermined range, and the first threshold, and
the second threshold is determined based on the third time interval and the fourth time interval.
