Abstract
A method and a communication apparatus for deciding a transmitting region for an allocated transmitting burst in a frame of an orthogonal frequency division multiplex access (OFDMA) system are provided. The communication apparatus comprises a decoder and a processing unit. The decoder decodes an MAP message, which is related to the allocated transmitting burst, into a plurality of parameters. The processing unit assigns a plurality of burst regions in the frame according to the parameters and decides a transmitting region according to the burst regions.

A method for deciding a transmitting region for an allocated transmitting burst in a frame of an orthogonal frequency division multiplex access (OFDMA) system, comprising:
- decoding via a decoder, an MAP message into a plurality of parameters, the MAP message relating to the allocated transmitting burst;
- assigning a first burst region in the frame according to the parameters;
- assigning a second burst region in the frame according to the parameters;
- and
- deciding the transmitting region according to the first burst region and the second burst region,
- wherein the MAP message comprises slots allocation information for at least one of mobile stations in an uplink sub-frame and is stored in a downlink sub-frame.
