Abstract: A method of a terminal may comprise: receiving a channel state information (CSI) request message from a base station, the CSI request message including first indication information indicating one of quantization configuration information of a first artificial intelligence (AI) model configured in the terminal to encode and transmit CSI; quantizing generated CSI feedback information based on the first indication information; and transmitting a CSI report message including the quantized CSI feedback information to the base station.

Abstract: An operation method of a terminal in a communication system may include: receiving, from a base station, a first reference signal through a use channel; generating subchannel state information for each of a plurality of subchannels of the use channel based on the first reference signal; compressing the subchannel state information using a first neural network encoder; forming a subchannel group including at least one subchannel; generating subchannel group state information from the compressed subchannel state information of the at least one subchannel belonging to the subchannel group by using a second neural network encoder; and transmitting the subchannel group state information to the base station.
