A method and a device for determining channel feedback information in a Long Term Evolution (LTE) system are provided. The method includes: obtaining an (N-1)th layer interference-plus-noise matrix in an LTE system, and obtaining an Nth layer interference-plus-noise matrix according to the (N-1)th layer interference-plus-noise matrix; and then, calculating a Signal to Interference plus Noise Ratio (SINR) corresponding to the Nth layer interference-plus-noise matrix according to the Nth layer interference-plus-noise matrix, and determining channel feedback information according to the SINR. It can be seen that, in the embodiments of the present invention, in a processing manner, a current layer interference-plus-noise matrix is calculated according to an obtained previous layer interference-plus-noise matrix through calculation in a calculation process of the channel feedback information, thus effectively reducing the calculation amount in the calculation process of the channel feedback information.
