4. A terminal for transmitting a feedback signal in a wireless communication system, the terminal comprising:
a wireless communication unit configured to transmit and receive data; and
a control unit configured to control the terminal,
wherein the control unit is further configured to:
control the wireless communication unit to receive, from a base station, a feedback information configuration including channel component information and grouping information;
control the wireless communication unit to receive, from the base station, a reference signal;
perform a channel measurement between the base station and the terminal based on the reference signal;
separate each of a plurality of channel elements of a channel obtained by the channel measurement according to components of the plurality of the channel elements based on the channel component information;
group the plurality of the separated channel elements of the channel based on the grouping information;
configure order sorting information associated with sorting an order of at least one channel element included in each group of the plurality of the separated channel elements;
configure probability distribution approximation information associated with probability distribution approximating the at least one channel element included in each group of the plurality of the separated channel elements; and
control the wireless communication unit to transmit feedback information including the configured order sorting information and the configured probability distribution approximation information.
