METHOD FOR TRANSMITTING AND RECEIVING DOWNLINK REFERENCE SIGNALS IN A WIRELESS COMMUNICATION SYSTEM HAVING MULTIPLE ANTENNAS
摘要
A method for transmitting and receiving downlink Reference Signals (RSs) in a wireless communication system using multiple antennas is disclosed. The downlink RS transmission method includes transmitting a first Orthogonal Frequency Division Multiplexing (OFDM) symbol in which RSs for a plurality of antenna port of first group are allocated in a predetermined order along a frequency axis, RSs for a plurality of antenna port of second group are allocated in a predetermined order along the frequency axis, and the RSs for the plurality of antenna port of first group are multiplexed in Code Division Multiplexing (CDM) with the RSs for the plurality of antenna port of second group by pairing each of the plurality of antenna port of first group with one of the plurality of antenna port of second group, and transmitting a second OFDM symbol in which the RSs for the plurality of antenna port of first group and the RSs for the plurality of antenna port of second group are positioned in an RS pattern being a frequency-domain shift of an RS pattern of the first OFDM symbol.
