DEMODULATION-REFERENCE-SIGNAL TRANSMISSION METHOD AND DEVICE IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention concerns a method whereby a base station transmits a demodulation reference signal in a wireless communication system, and the demodulation-reference-signal transmission method comprises the step of transmitting a reference-signal sequence mapped onto a resource element on a carrier wave, wherein the position of the resource element onto which the reference signal sequence has been mapped is set so as to respectively differ in accordance with one or more of: the carrier wave type; wherein a cell-specific reference signal has been transmitted; the multiplexing method; and the position of the resource block where the resource element is contained.
