Method and apparatus for scheduling data in a wireless communication system

1. A method of a terminal for communicating in a wireless communication system, the method comprising:

receiving first control information mapped on a first resource area;

identifying, based on the first control information, a second resource area and second control information, wherein the second resource area comprises a first area including the second control information and a second area including first data; and

decoding, based on the second control information, the first data,

wherein the first control information comprises resource allocation information allocating the second resource area.

2. The method of claim 1 , wherein the first resource area is different from the second resource area.

3. The method of claim 1 , further comprising:

identifying, based on resource allocation information related to a third resource area, the third resource area, wherein at least a part of the third resource area comprises third control information; and

decoding, based on the third control information, second data,

wherein the second control information comprises the resource allocation information related to the third resource area, and

wherein the third control information comprises resource allocation information related to a fourth resource area.

4. The method of claim 1 , further comprising:

determining, in a subframe, whether resource allocation information related to a third resource area, exists;

if the resource allocation information related to the third resource area exists in the subframe, identifying, based on the resource allocation information related to the third resource area, the third resource area, wherein the third resource area comprises third control information; and

decoding second data based on the third control information.

5. The method of claim 1 ,

wherein the second control information

comprises at least one of hybrid automatic repeat request (HARM)-related control information, new data indicator information, or redundancy version information.

6. The method of claim 1 , wherein the first resource area, the second resource area and a third resource area correspond to at least one of at least one subcarrier and at least one transmission time interval (TTI).

7. The method of claim 1 , wherein the first control information is mapped contiguously in a frequency area.

8. The method of claim 1 , wherein in time division duplex, the second control information transmitted on a downlink comprises resource allocation information related to an uplink signal.

9. The method of claim 8 ,

wherein the second resource area is configured based on one of a scheme of configuring subframes by sequentially concatenating a plurality of downlink subframes and a special subframe, a scheme of configuring subframes by allocating same radio resources in frequency to the subframes, or a scheme of configuring subframes by allocating independent radio resources in frequency to the subframes, and

wherein the special subframe comprises a downlink transmission available period, a guard period for accommodating downlink to uplink transition, and an uplink transmission available period.

10. The method of claim 1 , wherein the second resource area is channel-encoded based on a scheme of channel-encoding the second control information and the first data separately.

11. A terminal for communicating in a wireless communication system, the terminal comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to:

receive first control information mapped on a first resource area,

identify, based on the first control information, a second resource area and second control information, wherein the second resource area comprises a first area including the second control information and a second area including first data, and

decode, based on the second control information, the first data,

wherein the first control information comprises resource allocation information allocating the second resource area.

12. The terminal of claim 11 , wherein the first resource area is different from the second resource area.

13. The terminal of claim 11 ,

wherein the at least one processor is further configured to:

identify, based on resource allocation information related to a third resource area, the third resource area, wherein at least a part of the third resource area comprises third control information, and

decode, based on the third control information, second data,

wherein the second control information comprises the resource allocation information related to the third resource area, and

wherein the third control information comprises resource allocation information related to a fourth resource area.

14. The terminal of claim 11 , wherein the at least one processor is further configured to:

determine, in a subframe, whether resource allocation information related to a third resource area, exists,

if the resource allocation information related to the third resource area exists in the subframe, identify, based on the resource allocation information related to the third resource area, the third resource area, wherein the third resource area comprises third control information, and

decode second data based on the third control information.

15. The terminal of claim 11 ,

wherein the second control information

comprises at least one of hybrid automatic repeat request (HARM)-related control information, new data indicator information, or redundancy version information.

16. The terminal of claim 11 , wherein the first resource area, the second resource area and a third resource area correspond to at least one of at least one subcarrier and at least one transmission time interval (TTI).

17. The terminal of claim 11 , wherein the first control information is mapped contiguously in a frequency area.

18. The terminal of claim 11 , wherein in time division duplex, the second control information transmitted on a downlink comprises resource allocation information related to an uplink signal.

19. The terminal of claim 18 ,

wherein the second resource area is configured based on one of a scheme of configuring subframes by sequentially concatenating a plurality of downlink subframes and a special subframe, a scheme of configuring subframes by allocating same radio resources in frequency to the subframes, or a scheme of configuring subframes by allocating independent radio resources in frequency to the subframes, and

wherein the special subframe comprises a downlink transmission available period, a guard period for accommodating downlink to uplink transition, and an uplink transmission available period.

20. The terminal of claim 11 , wherein the second resource area is channel-encoded based on a scheme of channel-encoding the second control information and the first data separately.
