Abstract

A method for transmitting a reference signal includes selecting one of a first initialization value and a second initialization value, generating selection instruction information corresponding to the selected initialization value, transmitting the selection instruction information to a mobile station, generating a reference signal based on the selected initialization value, and transmitting the generated reference signal to the mobile station. A method for estimating a channel includes receiving selection instruction information indicating a selection of at least one of a first initialization value and a second initialization value, receiving a first reference signal based on the selection instruction information, generating a second reference signal based on an initialization value indicated as being selected by the selection instruction information, and estimating a channel state by comparing the first reference signal with the second reference signal.
