Method for transmitting and receiving resource allocation information in wireless communication system and apparatus therefor

Disclosed are a method for transmitting and receiving resource allocation information in a wireless communication system and an apparatus therefor. The method for a terminal to receive resource allocation information in a wireless communication system comprises the steps of: receiving, from a base station, an enhanced-physical downlink control channel (E-PDCCH) comprising a downlink (DL) grant from a particular resource domain; decoding a resource allocation (RA) field, which is in DCI format, in the received E-PDCCH; and determining, on the basis of the decoded RA field, whether a physical downlink shared channel (PDSCH) is transmitted from the domains in the particular resource domain from which the DL grant domain is excluded, or, from the domains in the particular resource domain in which an UL grant domain exists and from which the DL grant domain and the UL grant domain are excluded.
