1. A method for configuring a starting position of channel, performed by a Base Station (BS) in a wireless communication system, the method comprising:

  • transmitting a Physical Downlink Shared Channel (PDSCH) to a user equipment (UE); and

    transmitting an Enhanced Physical Downlink Control CHannel (EPDCCH) to the UE,wherein, if position information informing of a starting orthogonal frequency division multiplexing (OFDM) symbol of the EPDCCH is configured to the UE through a radio resource control (RRC) message, the starting OFDM symbol for the EPDCCH corresponds to the position information within the RRC message,wherein, if the position information is not configured to the UE through the RRC message, the starting OFDM symbol for the EPDCCH is an OFDM symbol next to a Physical Downlink Control Channel (PDCCH) region checked through a Physical Control Format Indicator Channel (PCFICH), andwherein, if the PDSCH is assigned by the EPDCCH in a same serving cell, a starting OFDM symbol for the PDSCH and a starting OFDM symbol for the EPDCCH are the same.
