Title:
METHOD FOR TRANSMITTING/RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM BY USING AUTO ENCODER, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/270651
Kind Code:
A1
Abstract:
The present specification provides a method for transmitting/receiving a signal in a wireless communication system by using an auto encoder. More particularly, the method performed by a transmission end comprises the steps of: transmitting, to a reception end, a reference signal for calculating a quantized channel information (QCI) index associated with determination of a particular auto encoder for (i) channel estimation and (ii) data transmission; receiving, from the reception end, a feedback comprising the QCI index; and transmitting the data to the reception end by using the particular auto encoder determined on the basis of (i) the QCI index and (ii) predefined corresponding relationship information, wherein the corresponding relationship information is information relating to the corresponding relationship between a plurality of quantized channels constructed by quantizing a complex channel space and a plurality of auto encoders pre-trained on the basis of the plurality of quantized channels, and the plurality of quantized channels are quantized so as to satisfy a particular condition on the basis of an error between an actual channel, associated with any one quantized channel from among the plurality of quantized channels, and the any one quantized channel.
