Method for transmitting and receiving data with superframe structure

Abstract

A method of transmitting and receiving data using a superframe structure is disclosed. A method for transmitting data through a superframe including a superframe header, includes generating the superframe which includes a data region including user data and includes a dedicated control region including data region allocation information indicating resource allocation for the data region, and transmitting the superframe. The dedicated control region is arranged at at least one of locations except for a subframe of the superframe header. A user equipment which does not have to transmit and receive data decodes only data region allocation information using information of the data region indicated by a dedicated control region, thereby minimizing power loss, reducing a feedback delay, and reducing system overhead using a superframe structure.

The invention claimed is:

 generating the superframe, the superframe including a superframe header, a data region including user data, and a dedicated control region including resource allocation information for the data region, the resource allocation information being as to resources scheduled according to downlink channel information through the dedicated control region,
 wherein the superframe header includes a common control region, 
 wherein the common control region includes first information as to a start location of the data region and second information as to a size of the data region, 
 wherein the first information indicates a number of successive subframes between the dedicated control region and the data region, and 
 wherein the second information indicates a number of successive subframes used for the data region; and 
   transmitting the superframe.   
     
     
       2. The method according to  claim 1 , wherein the common control region includes a broadcast channel (BCH). 
     
     
       3. The method according to  claim 1 , wherein the number of successive subframes between the dedicated control region and the data region is 0 or more. 
     
     
       4. The method according to  claim 1 , wherein the number of successive subframes used for the data region is 1, 2 or more. 
     
     
       5. The method according to  claim 1 , wherein a feedback channel is located ahead of the dedicated control region by a prescribed number of subframes. 
     
     
       6. The method according to  claim 1 , wherein the dedicated control region is arranged at at least one location except for a subframe of the superframe header. 
     
     
       7. The method according to  claim 1 , wherein the dedicated control region precedes the superframe header and includes information allocating available resources between a location of the dedicated control region and a location of the superframe header to the data region. 
     
     
       8. The method according to  claim 1 , wherein the dedicated control region is arranged in at least one subframe except for a legacy region including a legacy preamble. 
     
     
       9. The method according to  claim 1 , wherein the dedicated control region is arranged in subframes which are different according to a band. 
     
     
       10. The method according to  claim 1 , wherein the common control region further includes information as to a location of a feedback channel through which channel information of a downlink is transmitted. 
     
     
       11. The method according to  claim 1 ,
 wherein the superframe further includes 4 frames, each of the frames comprising 8 subframes, and each of the subframes including 6 Orthogonal Frequency Division Multiple Access (OFDMA) symbols.   
     
     
       12. A method for receiving data using a superframe which includes a data region including user data, a dedicated control region including dedicated control information for the data region, and a superframe header including a common control region, the method comprising:
 receiving information as to a location of a feedback channel through the common control region;   transmitting downlink channel information through the feedback channel; and   receiving resource allocation information as to resources scheduled according to the downlink channel information through the dedicated control region,   wherein the common control region includes first information as to a start location of the data region and second information as to a size of the data region,   wherein the first information indicates a number of successive subframes between the dedicated control region and the data region, and   wherein the second information indicates a number of successive subframes used for the data region.   
     
     
       13. The method according to  claim 12 , wherein a number of successive subframes from a start location of a subframe at which the data region is started is changed according to information transmitted through the common control region. 
     
     
       14. The method according to  claim 12 , wherein the dedicated control region is arranged at at least one location except for a subframe of the superframe header. 
     
     
       15. The method according to  claim 12 , wherein the dedicated control region precedes the superframe header and includes information allocating available resources between a location of the dedicated control region and a location of the superframe header to the data region. 
     
     
       16. The method according to  claim 12 , wherein the dedicated control region is arranged in at least one subframe except for a legacy region including a legacy preamble.
