METHOD AND A DEVICE FOR TRANSMITTING AND RECEIVING RESOURCE ALLOCATION INFORMATION IN A COMMUNICATION SYSTEM USING AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS METHOD, CAPABLE OF INCREASING SYSTEM CAPACITY BY REDUCING THE LOSS OF DATA ALLOCATION RESOURCE

摘要

PURPOSE: A method and a device for transmitting and receiving resource allocation information are provided to reduce processing overhead by identifying values of pilot tones in the final sub channel in which the MAP message is allocated by an MS.;CONSTITUTION: A discrambled signal is converted into a logic channel structure using a reverse sub-channelization pattern(804). An MS initializes a start point and a size of an individual MAP message(806). The MS determines whether the corresponding sub channel is the final sub channel of the individual MAP message(808). If the corresponding sub channel is not the final sub channel, the above process is performed again after increasing the size of the MAP message. If the corresponding sub channel is the final sub channel, the MCS level is initialized(812). The individual MAP message is demodulated by the reverse modulation, the deinterleaving, and decoding(816). If the CRC test is successful, the individual MAP message information is extracted(822).;COPYRIGHT KIPO 2010
