Abstract: A method for transmitting and receiving a signal by a terminal in a wireless communication system is disclosed in the present invention. More particularly, the method comprises the steps of: receiving an indicator for changing the usage of a specific subframe corresponding to a sub-component carrier from a network; determining whether near-end crosstalk between the sub-component carrier and another component carrier occurs if the usage of the subframe is changed according to the indicator; and transmitting and receiving a signal to and from the network through the sub-component carrier according to the changed usage if it is determined that the near-end crosstalk does not occur.
