In the field of mobile telecommunications, a method for checking a false alarm is provided. In the method, after a user in a Long Term Evolution (LTE) system receives control signaling for scheduling physical resources, Cyclic Redundancy Check (CRC) is performed on the control signaling; and if the CRC is passed, false alarm check is performed on the control signaling according to false alarm check bit(s) and padding bit(s) in the control signaling. An apparatus and a user equipment (UE) for checking a false alarm are also provided. According to the method, the apparatus, and the UE for checking a false alarm, the number of bits participating in the false alarm check is increased, thereby reducing the probability of false alarm occurrence, and improving receiving performance of the control signaling.
