METHOD AND APPARATUS OF TRANSMITTING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A method and device for transmitting a reference signal in a wireless communication system are provided to prevent AGI(Antenna Gain Imbalance), thereby efficiently increasing the performance of estimating a channel. CONSTITUTION: A reference signal sequence about each layer is generated. Each reference signal sequence is mapped on a resource element. An SC-FDMA(Single Carrier-Frequency Division Multiple Access) symbol is generated based on the reference signal sequence. Each SC-FDMA signal is mapped on antenna ports. Each SC-FDMA signal is mapped on a different antenna port. Each reference signal sequence is pre-coded.
