6. The method of claim 1 , wherein the first control information and the second control information are mapped within a specific subband.

7. The method of claim 1 , wherein the first control information is mapped contiguously in a frequency area or distributed across a total system bandwidth.

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 first subframe 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 first block is channel-encoded based on one of a scheme of channel-encoding the second control information and the first data jointly, or 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 resource predetermined between the terminal and a base station,

identify, based on the first control information, a first block in a first subframe, wherein the first block comprises second control information and first data, and

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

wherein the first control information comprises resource allocation information related to the first block, and

wherein the second control information comprises resource allocation information related to a second block in a second subframe.

12. The terminal of claim 11 ,

wherein a resource mapped to the first control information is different from a resource mapped to the first block, and

wherein the first control information is received from an outband signal.

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

identify, based on the resource allocation information related to the second block indicated by the first subframe, the second block in the second subframe, wherein the second block comprises third control information and second data, and

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

wherein the third control information comprises resource allocation information related to a third block in a third subframe.

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

determine, in the second subframe, whether the resource allocation information related to the second block indicated by the first subframe, exists,

if the resource allocation information related to the second block indicated by the first subframe does not exist, acquire, the resource allocation information related to the second block in the second subframe,

if the resource allocation information related to the second block indicated by the first subframe exists, identify, based on the resource allocation information related to the second block indicated by the first subframe, the second block in the second subframe, wherein the second block comprises third control information and second data, and

decode the second data based on the third control information in the second subframe.

15. The terminal of claim 11 ,

wherein the second control information further comprises channel state information about the first data, and

wherein the channel state information about the first data comprises at least one of hybrid automatic repeat request (HARQ)-related control information or modulation and coding scheme (MCS) information.
