Abstract

The MAC frame in a wireless communication system includes a terminal ID allocated to each of multiple terminals. At least one connection ID is allocated to each terminal having the terminal ID, and sub-carrier allocation information is allocated to each connection having the connection ID. The sub-carrier allocation information includes a sub-carrier allocation status for each sub-carrier, and the number of allocated information bits for each sub-carrier. The sub-carrier allocation status and the number of allocated information bits for each sub-carrier can be allocated, by sub-carriers, to the sub-carrier allocation information using a same number of bits; or the information on the sub-carrier allocation status is first allocated to the sub-carrier allocation information and the number of allocated information bits for each sub-carrier is allocated.

Claims

1. A method of designing a frame which is transferred from a transmitter to a receiver in a wireless communication system having a plurality of sub-carriers, the method comprising:

assigning, in the transmitter, a connection identification (ID) for identifying a connection between the transmitter and the receiver to the frame, the connection ID being associated with the receiver;

assigning, in the transmitter, a first information to the frame, the first information being associated with sub-carrier allocation and the connection ID;

assigning, in the transmitter, a second information to the frame, the second information being associated with a number of allocated information bits per sub-carrier and the connection ID; and

transmitting, from the transmitter to the receiver, the frame having the connection ID associated with the receiver, the first information, and the second information.

2. The method of claim 1, wherein the number of allocated information bits per sub-carrier is the same for all sub-carriers allocated to the connection ID.

3. The method of claim 1, further comprising allocating the connection ID, the first information and the second information to a downlink map information element included in the frame.

4. The method of claim 3, further comprising allocating the downlink map information element to a downlink map message included in the frame.

5. The method of claim 1, further comprising allocating the connection ID, the first information, and the second information to an uplink map information element included in the frame.

6. The method of claim 5, further comprising allocating the uplink map information element to an uplink map message included in the frame.

7. The method of claim 1, wherein the number of allocated information bits per sub-carrier is not the same for all sub-carriers allocated to the connection ID included in the frame.

8. A non-transitory computer readable medium comprising a computer readable computer program code for executing a method of designing a frame which is transferred from a transmitter to a receiver in a wireless communication system having a plurality of sub-carriers and instructions for causing a computer to implement the method, the method comprising:

allocating, in the transmitter, a connection ID for identifying a connection between the transmitter and the receiver to the frame, the connection ID being associated with the receiver;

assigning, in the transmitter, a first information to the frame, the first information being associated with sub-carrier allocation and the connection ID;

assigning, in the transmitter, a second information to the frame, the second information being associated with a number of allocated information bits per sub-carrier and the connection ID; and

transmitting, from the transmitter to the receiver, the frame having the connection ID associated with the receiver, the first information, and the second information.

9. The non-transitory computer readable medium of claim 8, wherein the number of allocated information bits per sub-carrier is the same for all sub-carriers allocated to the connection ID.

10. The non-transitory computer readable medium of claim 8, wherein the method further comprises allocating the connection ID, the first information, and the second information to a downlink map information element included in the frame.

11. The non-transitory computer readable medium of claim 10, wherein the method further comprises allocating the downlink map information element to a downlink map message included in the frame.

12. The non-transitory computer readable medium of claim 8, wherein the method further comprises allocating the connection ID, the first information, and the second information to an uplink map information element included in the frame.

13. The non-transitory computer readable medium of claim 12, wherein the method further comprises allocating the uplink map information element to an uplink map message included in the frame.

14. The non-transitory computer readable medium of claim 8, wherein the number of allocated information bits per sub-carrier is not the same for all sub-carriers allocated to the connection ID.
