Abstract

A method for transmitting a reference signal to a user equipment at a base station in a wireless communication system is disclosed. The method includes transmitting a control channel and the reference signal having a first pattern for the control channel to the user equipment and transmitting a data channel and the reference signal having a second pattern for the data channel to the user equipment, wherein reference signal density of the second pattern is determined based on a coherence time of the data channel, and the first pattern includes the second pattern.
