Abstract: A user equipment and a timing advance value updating method thereof are provided. The UE determines that a scheduling request transmission counter reaches a maximum number of SR transmission and determines whether a time alignment timer is still running after the scheduling request transmission counter reaches the maximum number of SR transmission. If the time alignment timer is still running, the UE drops the time alignment timer.

Abstract: A user equipment of a wireless communication system using carrier aggregation and a carrier aggregation control method thereof are provided. The user equipment includes an abnormal event detector and a processor electrically connected with the abnormal event detector. The abnormal event detector is configured to detect an abnormal event indicating that the user equipment is in an abnormal state. The processor is configured to control a component carrier of the wireless communication system in response to detecting the abnormal event. The carrier aggregation control method is applied to the user equipment to implement the operations.
