METHOD OF TRANSMITTING REFERENCE SIGNAL IN MULTIPLE ANTENNA SYSTEM

摘要

PURPOSE: A method of transmitting a reference signal in a multiple antenna system is provided to efficiently transmit an uplink reference signal from a terminal which uses plural power amplifiers. CONSTITUTION: A terminal acquires an SRS(Sounding Reference Signal) parameter from a base station(S110), and selects at least one power amplifier among plural power amplifiers(S120). The terminal transmits the SRS of a first antenna through the selected one or more power amplifiers(S130), and transfers the SRS of a second antenna through the selected one or more power amplifiers(S140). The terminal transmits the SRS of an Nth antenna through the selected one or more power amplifiers(S150).
