PURPOSE: A device for de-formatting a data channel frame is provided to detect a frequency index allocated to data according to an RS(Reference Signal) pattern, thereby shortening the demodulation time of a downlink data channel. CONSTITUTION: A PRB(Physical Resource Block) location searching unit(100) searches the location of a physical resource block according to a method for allocating a data channel in a mobile communication system. A physical resource block corresponding to the searched location is recorded in a buffer unit(120). A PRB reading and extracting unit(140) reads a physical resource block stored in the buffer unit. The PRB reading and extracting unit determines the number of REs according to whether an RS exists in the read PRB. The PRB reading and extracting unit outputs a counter signal according to the determined RE number. A counter unit(160) determines the increase value of a counter of an RE by the counter signal. A mapping unit(180) successively maps REs by applying the increase value of the RE counter. |
