For data transmission/reception in a communication system, a transmitter precodes data to be transmitted via at least two antennas, with use of at least one precoding matrix of a predetermined rank, and transmits the precoded data to a receiver. A receiver receives a signal which is precoded with a precoding matrix of a predetermined rank, detects the precoding matrix, calculates a sum rate corresponding to the detected precoding matrix, and feeds back quality information on a channel formed between a transmitter and the receiver when the calculated sum rate falls within a predetermined rank among sum rates calculated for all precoding matrixes.
