    • 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.

    • Disclosed is an uplink transmission power control method, by which a transmission power of an uplink signal is efficiently controlled while a terminal communicates with a plurality of base stations. The present invention includes the steps of computing command values for a plurality of base stations in a terminal in soft handover with a plurality of the base stations transmitting power control commands to the terminal and lowering uplink transmission power if the command values computed for a plurality of the base stations includes at least one power-down command. And, the present invention includes the steps of receiving a power control command transmitted from at least one base station, computing at least one command value according to the received power control command, and lowering uplink transmission power if the command value includes a transmission power-down command value.
