Abstract
The present invention relates to a method and an apparatus for transmission of sounding reference signals (SRS) in a wireless communication system, and a method and an apparatus for indicating transmission of SRS. A base station (eNodeB), which receives uplink reference signals from a plurality of user equipment (UEs), generates and transmits, to the UE, information of at least one set of parameters (and each item of information indicated by parameters within each of the parameter sets) which comprises some or all of a plurality of parameters used in SRS transmission for a second UE so as to indicate SRS transmission for the second UE in a resource domain comprising all or a part of a demodulation-reference signal (DM-RS) transmission resource domain of the first UE. The eNodeB transmits to the second UE, for SRS transmission therefor, DCI comprising indication information enabling a selection of one parameter set from among the parameter sets. The second UE, having received the DCI, allocates, on the basis of the previously selected plurality of parameters, an SRS in a resource domain comprising all or a part of a DM-RS transmission resource domain of the first UE and transmits same to the eNodeB. The SRS for the second UE can be transmitted using a remaining orthogonal resource in the resource space for DM-RS transmission for the first UE, that is, a non-precoded DM-RS resource, and thus the present invention has the advantage of securing additional resources for SRS transmissions in an environment in which a plurality of UEs are used.
