Assignee: LOCAILA, INC
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 7:
8. A user equipment comprising:
a communication interface device configured to communicate with another apparatus;
a processor; and
a memory configured to store at least one instruction executed through the processor,
wherein the processor is configured to receive a reference signal from a base station, to set a plurality of summation time intervals within a time interval in which the reference signal is receive, and acquire a plurality of snapshot vectors corresponding to the plurality of summation time intervals, to calculate a covariance matrix based on the plurality of snapshot vectors, and to estimate a reception delay time of the reference signal based on the covariance matrix; wherein the plurality of summation time intervals by shifting a start point of a summation time interval within the time interval in which the reference signal is received by an integer multiple of a sample time that is determined based on a sampling rate.
