METHOD AND APPARATUS FOR LIMITED FEEDBACK BASED ON MACHINE LEARNING IN WIRELESS COMMUNICATION SYSTEM

摘要

The present disclosure relates to a limited feedback method and apparatus based on machine learning in a wireless communication system. A feedback method in a wireless communication system according to an embodiment of the present disclosure includes: obtaining a received signal vector including a channel component and a noise component at a receiving end; generating feedback information by applying one or more of processing through at least one first layer, processing through a second layer, or processing through a quantization layer to the received signal vector at the receiving end; and transmitting the feedback information from the receiving end to the transmitting end. The quantization may include a stochastic binarization process.
