Signal transmission / reception method based on dynamic radio resource change in radio communication system and apparatus therefor

摘要

A method for transmitting / receiving a signal to / from a base station in a TDD (Time Division Duplex) communication system is provided. The method includes receiving reference subframe setting information using system information, receiving operating subframe setting information using dynamic signaling, and a downlink defined by the operating subframe setting information. Receiving an uplink grant for transmission of an uplink signal in a subframe; determining a validity of a specific uplink subframe for transmission of the uplink signal indicated by the uplink grant; And transmitting the uplink signal to the base station when the specific uplink subframe is valid.
