Abstract: Methods, devices and a system for transmitting an SRS and a UE are provided. A network node transmits an SRS configuration information set to a UE, wherein the SRS configuration information set includes first configuration information indicating the configuration of a first SRS and second configuration information indicating the configuration of a second SRS, wherein the first SRS is transmitted on a cellular uplink and used for performing uplink channel measurement during cellular communication; and the second SRS is transmitted on a D2D link and used for performing channel measurement of the D2D link during D2D communication. The solution addresses the problem of the configuration and the transmission of a reference signal existing in the conventional art when D2D communication is introduced into a cellular system, realizes the compatibility of D2D communication with cellular communication and avoids the noticeable increase in UE design and realization complexity.
