<p>A downlink data transceiving method and apparatus for combining received data in an OFDM system are provided to enable a terminal to naturally perform combining of data without an additional operation by enabling a base station to inform the terminal of combining information and enabling combinable cells to use the same radio resources and the same scrambling sequences during data transmission, and enable the terminal to combine channel estimation values calculated from pilot signals of each cell, in order to compensate for received data signals, thereby properly compensating for channels. A downlink data transceiving method for combining received data in an OFDM(Orthogonal Frequency Division Multiplexing) system comprises the following steps of: enabling a terminal(206), located in an overlaid region between a serving cell(202) and at least one non-serving cell(204), to calculate the first channel estimation value after receiving the first pilot signal for identification of the serving cell(202), calculate the second channel estimation value after receiving the second pilot signal for identification of the non-serving cell(204), and calculate the final channel estimation value by combining the first and second channel estimation values; and enabling the terminal(206) to receive data signals, in which the first data signal and the second data signal are combined, and perform channel compensation of the combined data signals by using the final channel estimation value.</p> |
