The UE performs transmission/reception of data, etc., via the upper layer device 3910. The UE performs transmission/reception of control messages via the control message processor 3915. When the UE transmits a control signal or data to an ENB, the controller 3920 controls: the multiplexer 3905 to multiplex data; and the transmitter 3900 to transmit the processed data. When the UE receives a signal or data, the controller 3920 controls: the receiver 3900 to receive physical signals; and the demultiplexer 3905 to de-multiplex the received signal, and transfers the processed signal to the upper layer 3910 or the control message processor 1215, according to information in the individual messages. For example, the messages of the RRC layer correspond to control messages.
Meanwhile, although the embodiment of the UE is implemented in such a way to include a number of blocks that perform different functions, it should be understood that the embodiment is an example and the present disclosure is not limited thereto. For example, the embodiment can be modified in such a way that the function of the demultiplexer 3905 is performed by the controller 3920.
The controller 3920 of the UE according to an embodiment of the present disclosure is capable of: receiving a control message from an ENB; reporting the capability according to the instruction of the ENB; measuring a configured licensed or unlicensed band according to the instruction of the ENB; creating a measurement result message according to a preset condition, via the control message processor; and transmitting the crated message to the ENB.
