<p>A method and an apparatus for transmitting and receiving a radio signal are provided to improve a receiving performance by using a weight set selected from a plurality of weight sets. An apparatus for transmitting and receiving a radio signal includes a stacking unit(12), a first selection unit(13), a second selection unit(15-1), a conversion unit(16-1), and a transmission unit(18-1). The stacking unit stacks a plurality of weight sets to correspond to a plurality of transmission blocks. The weight sets are allocated to the transmission blocks partitioned by a time axis and a frequency axis. The first selection unit selects one transmission block from the transmission blocks. The second selection unit selects one weight from one weight set allocated to the transmission block. The conversion unit converts a data signal based on the weight, and generates a conversion signal. The transmission unit transmits the conversion signal using the transmission block.</p> |
