APPARATUS AND METHOD FOR TRANSMITTING SOUNDING REFERENCE SIGNAL, AND TRANSMISSION INDICATING APPARATUS AND METHOD USING THE SAME

摘要

PURPOSE: A SRS(Sounding Reference Signal) transmission method for transmitting a sound reference signal using non-precoded DM-RS(Demodulation Reference Signal) resources, an apparatus thereof and a SRS transmission instruction method for the same and an apparatus thereof are provided to transmit SRS of second UE(User Equipment) using non-precoded DM-RS. CONSTITUTION: An eNodeB(Evolved-Node-B) generates at least one parameter set information consisting of all or part of multiple parameters used for the SRS transmission of second UE. The eNodeB transmits the parameter set information to UE(S410). Instruction information capable of determining one out of parameter sets is included in DCI(Downlink Control Information) for the SRS transmission of the second UE. The DCI including the instruction information is transmitted to the second UE(S420). The SRS of the second UE transmitted from a resource area including all or part of the DM-RS transmission resource area of first UE is received from the second UE(S430).
