Abstract: A UE receives a radio signal via a receive beam. The UE controls the receive beam in a first state or in a second state where control of the receive beam is different from that of the first state. The UE directs at least one receive beam to a serving cell and directs another receive beam to a direction different from the serving cell in a case of controlling the receive beam in the second state and executing configuration regarding a secondary cell.
