Method for allocating radio resource in wireless communication system and method for transmitting or receiving data using the same

1. A method for allocating a radio resource in a wireless communication system, the method comprising:

defining a plurality of resource regions within a frame, a resource region comprising at least one orthogonal frequency division multiple access (OFDMA) symbol and at least one subchannel;

configuring radio resource allocation information indicating which resource region selected from the plurality of resource regions is allocated to a user equipment (UE), and transmitting the radio resource allocation information to the UE,

wherein the radio resource allocation information comprises at least one resource region identifier (ID), a resource region ID indicating a resource region selected from the plurality of resource regions;

a duration indicating the number of consecutive resource regions allocated to the UE; and

an optional indicator indicating whether resource region identifiers of the plurality of resource regions are indexed first on the frequency axis or the time axis, wherein the consecutive resource regions have consecutive resource region IDs.

2. The method of claim 1 , wherein the resource regions allocated to the UE form a rectangle, and the resource region ID indicates a resource region positioned at the edge of the rectangle.

3. The method of claim 1 , wherein the radio resource allocation information comprises a resource region ID for the first resource region allocated to the UE.

4. The method of claim 1 , wherein the radio resource allocation information comprises a resource region ID for the first resource region allocated to the UE and another resource region ID for the first resource region allocated to another UE.

5. The method of claim 1 , wherein the frame is divided into at least one permutation zone, the radio resource allocation information comprises permutation zone information including:

an OFDMA symbol offset indicating the start location of a permutation zone in time domain;

a subchannel offset indicating the start location of the permutation zone in frequency domain;

the number of resource regions in the permutation zone; and

a size of one resource region included in the permutation zone.

6. A method for transmitting or receiving data by using a resource region including at least one OFDMA symbol and at least one subchannel, the method comprising:

receiving radio resource allocation information; and

transmitting or receiving data through at least one resource region indicated by the radio resource allocation information,

wherein the radio resource allocation information comprises at least one resource region identifier (ID), a resource region ID indicating a resource region selected from the plurality of resource regions;

a duration indicating the number of consecutive resource regions allocated to a user equipment (UE); and

an optional indicator indicating whether resource region identifiers of the plurality of resource regions are indexed first on the frequency axis or the time axis, wherein the consecutive resource regions have consecutive resource region IDs.

7. The method of claim 6 , wherein the plurality of resource regions are included in a permutation zone and the permutation zone is defined via permutation zone information included in the radio resource allocation information.

8. The method of claim 7 , wherein the permutation zone information includes an OFDMA symbol offset indicating the start location of a permutation zone in time domain;

a subchannel offset indicating the start location of the permutation zone in frequency domain;

the number of resource regions in the permutation zone; and

a size of one resource region included in the permutation zone.
