APPARATUS AND METHOD OF TRANSMITTING AND RECEIVING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM USING MULTIPLE-INPUT AND MULTIPLE-OUTPUT

摘要

An apparatus and method is proved that transmits and receives Reference Signals (RSs) in a wireless communication system using Multiple-Input and Multiple-Output (MIMO). A system adapted to the method is provided. The method includes: determining the number of RS transmission to two or more antennas, respectively, as the number of antennas included in respective ports, wherein each port include one or more antennas; creating transmit patterns so that they cyclically differ from each other every the number of RS transmission to transmit the created transmit patterns the number of RS transmission times; and mapping the RSs to one or more antennas according to the created, respective patterns, and transmitting the RSs in order.

1. A method of transmitting Reference Signals (RSs) in a wireless communication system using Multiple Input Multiple Output (MIMO), comprising:
determining a number of RSs transmission to two or more antennas, respectively, corresponding to a number of antennas included in respective ports, wherein each port includes one or more antennas; creating transmit patterns that cyclically differ from each other, wherein a number of RS transmissions to transmit the created transmit patterns corresponds to a number of RSs transmission times; mapping the RSs to the one or more antennas according to the created transmit patterns; and transmitting the RSs in order.
