Patent ID: 7924779

Claim:
An apparatus for transmitting a sub-channel signal in a mobile communication system, the apparatus comprising: a sub-channel allocator for allocating a sub-channel for transmission of data in accordance with permuted positions at which the data is stored, and providing the data to the sub-channel for transmission of the data through the sub-channel in each time period unit; and a transmitter for transmitting the sub-channel signal from the sub-channel allocator; wherein the sub-channel allocator comprises: a first buffer for storing the data at permuted positions according to a control; a permutation unit for permuting positions at which the data will be stored in the first buffer; a sub-channel allocating unit for allocating a sub-channel for transmitting the data of the permuted positions, and controlling the data of the permuted positions to be stored in a second buffer, so that the data of the permuted positions can be transmitted through the sub-channel in each time period unit; and the second buffer for storing the data of the permuted positions by control of the sub-channel allocating unit.
