Method and device for transmitting or receiving control signal and data signal in wireless communication system
The present disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety-related services, and the like) on the basis of 5G communication technologies and IoT-related technologies. The present disclosure relates to a method of a terminal in a communication system, the method comprising the steps of: receiving carrier aggregation configuration information from a base station; receiving offset information for a frame boundary between a first cell and a second cell from the base station; receiving, from the base station, control information including time domain resource allocation information indicating an interval between a slot in which data scheduled by the control information transmitted or received and a slot in which the control information is received into the first cell; identifying an index of the slot in which the data is transmitted or received, on the basis of the offset information and the time domain resource allocation information; and transmitting the data to or receiving the data from the base station on the second cell in the slot of the identified index.
1. A method performed by a terminal in a communication system, the method comprising:
receiving, via higher layer signaling, first slot offset information for a first slot offset between two cells for carrier aggregation with un-aligned frame boundaries;

identifying a second slot offset based on the DCI;
identifying a second slot of a scheduled cell for the data based on the first slot of the scheduling cell, the first slot offset, and the second slot offset; and
communicating the data in the second slot of the scheduled cell.
2. The method of claim 1 , wherein the second slot of the scheduled cell is identified based on a subcarrier spacing of the scheduling cell and a subcarrier spacing of the scheduled cell.
3. The method of claim 1 , wherein the first slot offset information is based on a specific subcarrier spacing.
4. The method of claim 1 , wherein a value of the first slot offset information is available to be a negative number and a positive number.
5. The method of claim 1 , wherein the scheduling cell and the scheduled cell are configured for the carrier aggregation.
6. A method performed by a base station in a communication system, the method comprising:
transmitting, via higher layer signaling, first slot offset information for a first slot offset between two cells for carrier aggregation with un-aligned frame boundaries;
transmitting, in a first slot of a scheduling cell, downlink control information (DCI) scheduling data; and
communicating the data in a second slot of a scheduled cell,
wherein the second slot is indicated based on the first slot of the scheduling cell, the first slot offset, and a second slot offset indicated based on the DCI.
7. The method of claim 6 , wherein the second slot of the scheduled cell is indicated based on a subcarrier spacing of the scheduling cell and a subcarrier spacing of the scheduled cell.
8. The method of claim 6 , wherein the first slot offset information is based on a specific subcarrier spacing.
9. The method of claim 6 , wherein a value of the first slot offset information is available to be a negative number and a positive number.
10. The method of claim 6 , wherein the scheduling cell and the scheduled cell are configured for the carrier aggregation.
11. A terminal in a communication system, the terminal comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
receive, via higher layer signaling, first slot offset information for a first slot offset between two cells for carrier aggregation with un-aligned frame boundaries,
receive, in a first slot of a scheduling cell, downlink control information (DCI) scheduling data,
identify a second slot offset based on the DCI,
identify a second slot of a scheduled cell for the data based on the first slot of the scheduling cell, the first slot offset, and the second slot offset, and
communicate the data in the second slot of the scheduled cell.
12. The terminal of claim 11 , wherein the second slot of the scheduled cell is identified based on a subcarrier spacing of the scheduling cell and a subcarrier spacing of the scheduled cell.
13. The terminal of claim 11 , wherein the first slot offset information is based on a specific subcarrier spacing.
14. The terminal of claim 11 , wherein a value of the first slot offset information is available to be a negative number and a positive number.
15. The terminal of claim 11 , wherein the scheduling cell and the scheduled cell are configured for the carrier aggregation.
16. A base station in a communication system, the base station comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
transmit, via higher layer signaling, first slot offset information for a first slot offset between two cells for carrier aggregation with un-aligned frame boundaries,

communicate the data in a second slot of scheduled cell,
wherein the second slot is indicated based on the first slot of the scheduling cell, the first slot offset, and the second slot offset indicated based on the DCI.
17. The base station of claim 16 , wherein the second slot of the scheduled cell is indicated based on a subcarrier spacing of the scheduling cell and a subcarrier spacing of the scheduled cell.
18. The base station of claim 16 , wherein the first slot offset information is based on a specific subcarrier spacing.
19. The base station of claim 16 , wherein a value of the first slot offset information is available to be a negative number and a positive number.
