Abstract

A method of wireless communication determines whether the timing of a non-serving RAT is known. When the timing is known and it is time to report on the non-serving RAT, the UE clears enough consecutive time slots to verify the identity of the base station in the non-serving RAT. During the cleared time slots the identity of the base station is verified. When the timing is unknown and it is time to report on the non-serving RAT, a UE clears enough consecutive time slots to measure the timing of the non-serving RAT and to verify the identity of a base station in the non-serving RAT. During the cleared time slots, the timing is acquired and the identity of the base station is verified.
