Abstract: A method for configuring a time division duplex (TDD) of a user equipment in a communication system, according to one embodiment of the present invention, comprises the steps of: receiving from a base station a first TDD configuration; receiving from the base station a message including information related to a dynamic TDD configuration; receiving a second TDD configuration according to the received information related to the dynamic TDD configuration; receiving from the base station an uplink grant; and determining whether to apply the first TDD configuration or the second TDD configuration based on a method by which the unlink grant is received. According to one embodiment of the present invention, the advantages of configuring a shorter cycle of the TDD to the user equipment supporting the TDD in a wireless communication system, and rapidly configuring the TDD to the user equipment variably according to a communication situation are provided.
