Provided are a method and apparatus for transmitting/receiving signals with a terminal in a time division duplex (TDD) system. The method comprises: a scheduling information and pattern information receiving step, wherein a second subframe is scheduled within a first subframe; and a step for transmitting/receiving signals with a base station from the second subframe, wherein the second subframe is used as a downlink subframe if scheduling information is a downlink grant which schedules a downlink data channel, the second subframe is used as an uplink subframe if scheduling information is an uplink grant which schedules an uplink data channel, and the pattern information is information indicating positions of time gaps to prevent interference in the second subframe.
