Abstract

Provided are a method and apparatus for transmitting an uplink signal by a terminal. The method comprises: a step of receiving uplink subframe-type information from a first base station; a step of configuring an uplink subframe having one of a plurality of predetermined subframe structures on the basis of the uplink subframe-type information; and a step of transmitting an uplink signal from the thus-configured uplink subframe to the first base station. The uplink subframe is a subframe which overlaps, in a time domain, with a downlink subframe for transmitting a downlink control signal from a second base station adjacent to the first base station. The plurality of subframe structures each have different reference-signal locations.
