METHOD AND APPRATUS FOR TRANSMITTING AND RECEIVING REFERENCE SIGNAL

摘要

PURPOSE: A reference signal transceiving method and a device thereof are provided to transmit a reference signal to each group by dividing an antenna port transmitting an uplink reference signal into predetermines groups. CONSTITUTION: An RF(Radio Frequency) unit(1010) requests an SRS(Sounding Reference Signal) request to a downlink control channel. The RF unit receives SRSs according to the SRS request. A processor(1030) sets a parameter set required for SRS transmission. The processor estimates a state of an antenna port channel for SRS transmission based on the received SRSs. Antenna ports used for uplink transmission are divided into a first antenna port group and a second antenna port group.
