Abstract
A method for transmitting feedback information by a terminal may comprise: multiplying each of a left side and a right side of a matrix, which is related to a channel measured by the terminal, by a transformation matrix, so as to obtain a first matrix; performing a first transformation which transforms elements other than a predetermined number of elements having a larger size among elements of the first matrix to zero, or performing a second transformation which transforms elements other than elements exceeding a threshold value to zero, so as to obtain a second matrix; quantizing the second matrix so as to obtain a third matrix; configuring a vector by selecting a specific portion in the third matrix according to a predetermined pattern; configuring, into bits, an output obtained by multiplying the configured vector by a sensing matrix for compression sensing; and transmitting the output bits to a base station.
