The method includes receiving, from a base station (BS), control information; and receiving, from the BS, downlink data on an unlicensed band cell (UCell) based on the control information. Further, in case of: the control information received on another serving cell, the downlink data is received in a first time resource, and the control information received on the UCell, the downlink data is received in a second time resource, and the second time resource is smaller than the first time resource. ## Claims ### Claim 1 A method for receiving a signal by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station (BS), control information; and receiving, from the BS, downlink data on an unlicensed band cell (UCell) based on the control information, wherein in case of: the control information received on another serving cell, the downlink data is received in a first time resource, and the control information received on the UCell, the downlink data is received in a second time resource, and wherein the second time resource is smaller than the first time resource. ### Claim 2 (depends on 1) The method of claim 1, wherein the another serving cell is a cell configured in a licensed band. ### Claim 3 (depends on 1) The method of claim 1, wherein the downlink data is received on a downlink burst configured in a certain number of time resources. ### Claim 4 (depends on 3) The method of claim 3, wherein the downlink burst is configured in at least one first time resource and the second time resource. ### Claim 5 (depends on 1) The method of claim 1, wherein the control information is received based on a pre-scheduling scheme, and wherein the pre-scheduling scheme denotes a scheme to transmit the control information earlier than the downlink data. ### Claim 6 (depends on 1) The method of claim 1, wherein a starting time of the downlink data is determined based on a starting position or size of the second time resource. ### Claim 7 (depends on 1) The method of claim 1, wherein in case of the second time resource configured, a starting time of the downlink data, configured through higher-layer signaling, is invalid. ### Claim 8 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), control information; and receive, from the BS, downlink data on an unlicensed band cell (UCell) based on the control information, wherein in case of: the control information received on another serving cell, the downlink data is received in a first time resource, and the control information received on the UCell, the downlink data is received in a second time resource, and wherein the second time resource is smaller than the first time resource. ### Claim 9 (depends on 8) The device of claim 8, wherein the another serving cell is a cell configured in a licensed band. ### Claim 10 (depends on 8) The device of claim 8, wherein the downlink data is received on a downlink burst configured in a certain number of time resources. ### Claim 11 (depends on 9) The device of claim 9, wherein the downlink burst is configured in at least one first time resource and the second time resource. ### Claim 12 (depends on 8) The device of claim 8, wherein the control information is received based on a pre-scheduling scheme, and wherein the pre-scheduling scheme denotes a scheme to transmit the control information earlier than the downlink data. ### Claim 13 (depends on 8) The device of claim 8, wherein a starting time of the downlink data is determined based on a starting position or size of the second time resource. ### Claim 14 (depends on 8) The device of claim 8, wherein in case of the second time resource configured, a starting time of the downlink data, configured through higher-layer signaling, is invalid. ### Claim 15 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), control information;
