Method for transceiving enhanced physical downlink control channel in wireless access system supporting unlicensed band, and device supporting same

A user equipment (UE) for receiving downlink data in a wireless access system, the UE comprising:

• a transmitter;
• a receiver;
• and
• at least one processor coupled with the transmitter and the receiver,
• wherein the at least one processor is configured to:
• receive an enhanced physical downlink control channel (EPDCCH) within enhanced resource element groups (EREGs) in a time resource within a subframe for an unlicensed band cell (UCell), wherein the EPDCCH comprises control information on scheduling the UCell;
• and
• receive the downlink data on the UCell based on the control information,
• wherein the EREGs are indexed starting from a symbol included in the subframe, and
• wherein a starting boundary of the time resource is different from a starting boundary of the subframe and the symbol is different from a 1st symbol of the subframe.

A base station (BS) for transmitting downlink data in a wireless access system, the BS comprising:

• a transmitter;
• a receiver;
• and
• at least one processor coupled with the transmitter and the receiver,
• wherein the at least one processor is configured to:
• transmit an enhanced physical downlink control channel (EPDCCH) within enhanced resource element groups (EREGs) in a time resource within a subframe for an unlicensed band cell (UCell), wherein the EPDCCH comprises control information on scheduling the UCell;
• and
• transmit the downlink data on the UCell based on the control information,
• wherein the EREGs are indexed starting from a symbol included in the subframe, and
• wherein a starting boundary of the time resource is different from a starting boundary of the subframe and the symbol is different from a 1st symbol of the subframe.
