US 10,320,460 B2 · Method for transmitting signal through high-frequency band in wireless communication system, and apparatus therefor

Abstract

A method for a transmitting end transmitting a signal to a receiving end in a wireless communication system is provided. The method includes receiving, from the receiving end, information on a first precoder and a second precoder which are for a channel between the transmitting end and the receiving end and transmitting a signal to the receiving end based on the first precoder where the signal is transmitted to the receiving end based on the second precoder if the receiving performance of the receiving end based on the first precoder is greater than or equal to a threshold value.

Dependent claims

A method of transmitting a signal by a base station (BS) in a wireless communication system, the method comprising:

receiving, from a user equipment (UE), first information related to a first precoder and a second precoder;
precoding a first signal based on the first precoder and transmitting the precoded first signal to the UE;
receiving second information related to a reception quality of the transmitted precoded first signal;
determining an amount of change in the reception quality based on the received second information;
and
precoding a second signal using the second precoder and transmitting the precoded second signal to the UE when the determined amount of change is equal to or greater than a threshold value,
wherein each of the first and the second precoders is a matrix for precoding the signal.
