Claim 0:
1. A method of wireless communication for a user equipment (UE), comprising:
estimating a time of arrival of different multipath components of a downlink signal from a base station, wherein the different multipath components comprise a first cluster of multipath components and a second cluster of multipath components, wherein the first cluster corresponds to a first physical layer signal and the second cluster corresponds to a second physical layer signal;
determining an existence of a false base station (FBS) based on a difference between times of arrival of the first cluster and the second cluster exceeding a threshold amount of time, wherein the threshold amount of time comprises at least one orthogonal frequency division multiplexing (OFDM) time-domain symbol duration; and
performing a mitigation operation in response to determining the existence of the FBS.
