摘要:
There is provided a method for placing reference signals in a wireless communication system. The method includes preparing a plurality of sub-frames for a plurality of antennas, placing a reference signal for one sub-frame and placing a reference signal for another sub-frame not to overlap with the reference signal for one sub-frame, wherein the reference signal for one sub-frame and the reference signal for another sub-frame are successively placed on contiguous OFDM symbols or on the contiguous sub-carriers. Channel estimation or data demodulation can be prevented from performance degradation.
