Provided is a method for measurement reporting by user equipment (UE) in a wireless communication system. The method comprises: evaluating a first measurement result and deciding whether a first reporting condition has been satisfied; evaluating a second measurement result and deciding whether a second reporting condition has been satisfied; and transmitting a measurement reporting message to a network, if the first measurement result satisfies the first reporting condition. If the second measurement result satisfies the second reporting condition within a specific time interval from the time of satisfying the first reporting condition, then the measurement reporting message includes the first measurement result and the second measurement result.
