Abstract
The disclosure relates to a 5generation (5G) or pre-5G communication system for supporting a higher data rate after a 4generation (4G) communication systems such as long term evolution (LTE). The disclosure is for reconstructing a downlink channel in a wireless communication system. An operation method for a base station is provided. The operation method includes the steps of transmitting downlink reference signals (RSs) to a terminal, receiving an indication of a first channel matrix estimated by the terminal and at least one uplink RS; estimating a second channel matrix on the basis of the at least one uplink RS, and on the basis of the first channel matrix and the second channel matrix, reconstructing channel information to be used for data transmission.
