<p>Disclosed are a method and an apparatus for determining an uplink demodulation - reference signal (DM-RS) sequence. According to the present invention, the method for determining the reduced DM-RS sequence comprises: a step in which a terminal receives information on the number of resource blocks allocated for the uplink DM-RS sequence reduced in a single slot of an uplink sub-frame; and a step in which the terminal determines the uplink DM-RS sequence to be mapped to the uplink sub-frame based on information on the number of the allocated recourse blocks, wherein the reduced uplink DM-RS sequence includes first and second reduced uplink DM-RS sequences which are generated based on a first circulation shift field value when the number of the allocated resource blocks is an even number, and the reduced uplink DM-RS sequence includes third and fourth reduced uplink DM-RS sequences which are generated based on a first circulation shift field value when the number of the allocated resource blocks is an odd number.</p> |
