Abstract:
A method in which a first communication module of a terminal transmits channel measurement information to a base station in a wireless communication system and a device therefor are disclosed in the present invention. Specifically, the method comprises the steps of: receiving a message indicating an operation start of at least one second communication module coexisting in the terminal from the second communication module; determining an unusable frequency due to in-device coexistence (IDC) interference on the basis of information on an operating frequency of the first communication module and an operating frequency of the second communication module; and transmitting an IDC interference indication message including channel measurement information corresponding to the determined unusable frequency to the base station.
