Method for configuring and scheduling partial subframe in wireless access system supporting unlicensed band, and device for supporting same

A device for receiving a signal in a wireless communication system, the device comprising:

• a memory;
• and
• at least one processor coupled with the memory and configured to:
• receive, from a base station (BS), downlink control information (DCI) by monitoring a physical downlink control channel (PDCCH);
• and
• receive, from the BS, downlink data in an unlicensed band cell (UCell) based on the DCI,
• wherein i) based on being configured to monitor the PDCCH on the Ucell, the downlink data is received starting in at least one of a first time resource or a second time resource,
• wherein ii) based on being configured to monitor the PDCCH on another serving cell, the downlink data is received starting in the second time resource and the UE is not expected to be scheduled with the downlink data starting in the first time resource,
• wherein the first time resource is configured as a first number of orthogonal frequency divisional multiplexing (OFDM) symbols,
• wherein the second time resource is configured as 14 number of OFDM symbols, and
• wherein the first number is less than 14.

A method for transmitting a signal by a base station (BS) in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), a physical downlink control channel (PDCCH) carrying downlink control information (DCI);
• and
• transmitting, to the UE, downlink data in an unlicensed band cell (UCell) based on the DCI,
• wherein i) based on the UE being configured to monitor the PDCCH on the Ucell, the downlink data is transmitted starting in at least one of a first time resource or a second time resource,
• wherein ii) based on the UE being configured to monitor the PDCCH on another serving cell, the downlink data is transmitted starting in the second time resource and the downlink data starting in the first time resource is not scheduled to the UE,
• wherein the first time resource is configured as a first number of orthogonal frequency divisional multiplexing (OFDM) symbols,
• wherein the second time resource is configured as 14 number of OFDM symbols, and
• wherein the first number is less than 14.
