Method and apparatus for estimating channel in wireless communication system

Abstract

A method performed by a receiver in a wireless communication system, includes: determining a first channel estimation value, based on a demodulation reference signal (DM-RS) symbol in a resource block; detecting a first data symbol, based on the first channel estimation value; determining whether to obtain a second channel estimation value, based on the first data symbol; in a case that the second channel estimation value is obtained, detecting a second data symbol, based on the second channel estimation value; and performing channel decoding on the second data symbol.
