In particular, the method includes the steps of: setting resource blocks for the EPDCCH; re-indexing by permutation indexes of the resource blocks; defining an Enhanced Control Channel Element (ECCE) for each of the re-indexed resource blocks; selecting the ECCEs in a number corresponding to the aggregation level of the EPDCCH; and transmitting the EPDCCH to the terminal using the selected ECCEs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for setting search regions for downlink control channels in wireless communication systems and apparatus for same","description":"The present invention relates to a method for transmitting an Enhanced Physical Downlink Control Channel (EPDCCH) from a based station to a terminal in a wireless communication system.
