Abstract

The present invention provides a method and an apparatus for transmitting reference signals in a radio communication system. Said method comprises the steps of generating orthogonal frequency division multiplexing (OFDM) symbols for data and reference signal elements, and transmitting said OFDM symbols to a base station. The present invention provides an effective method for transmitting reference signals in a radio communication system.
