Abstract: The present disclosure is to perform multiuser precoding in a wireless communication system. A method of operating a device for performing multiuser precoding in a wireless communication system may comprise transmitting configuration information related to channel state information (CSI) feedback to candidate devices, transmitting reference signals corresponding to the configuration information, receiving CSI feedback signals from the candidate devices, determining precoding vectors for participating devices that are at least part of the candidate devices, performing precoding for data to the participating devices using the precoding vectors, and transmitting the precoded data. The participating devices may be determined based on information including magnitude values of precoding vectors for the candidate devices determined by a decoder neural network based on the CSI feedback signals generated by an encoder neural network.

Abstract: The present disclosure provides a method for reporting, by a terminal, channel state information (CSI) in a wireless communication system. More specifically, the method includes: receiving, from a base station, a pilot signal related to calculation of a quantization rule, in which the quantization rule is determined based on an empirical distribution of an encoder neural network output of the terminal; transmitting, to the base station, quantization rule information related to the quantization rule calculated based on the pilot signal; and receiving, from the base station, information on a gradient calculated based on the quantization rule information, and the quantization rule information includes information on an empirically calculated variance with respect to the empirical distribution of the encoder neural network output.

Abstract: A transmission device in a wireless communication system: determines an encoder having S outputs from among encoders supported by the transmission device, on the basis of the number B of feedback bits, wherein B=S×Q; encodes CSI through the encoder to output S real number values; determines B-bit encoded CSI including Q bits indicating the S real number values, respectively; and transmits the B-bit encoded CSI. The encoders may have different numbers of outputs from each other, and the different numbers of outputs may be predetermined for different feedback bit number ranges.
