User equipment that is capable of communicating by using M (M is greater than or equal to 2) component carriers (CCs) includes N (N is greater than or equal to 2) communication units for executing radio communication with a base station by using each of the M CCs, a controller for individually controlling an operation mode of each of the N communication units; and a timer for reporting to the controller that a constant time period is elapsed without receiving a further control signal, after receiving, by a communication unit of the N communication units, a control signal from the base station. When a report from the timer is received for a specific communication unit of the N communication units, the controller controls the operation mode of the specific communication unit, so that the operation mode the specific communication unit discontinuously transitions to an active mode. |
