<p>The present invention discloses a configuration method for a Sounding Reference Signal (SRS) in a Long Term Evolution-Advanced (LTE-A) system. The method includes that a base station triggers one or more User Equipments (UEs) to transmit non-periodic SRSs in one or more uplink sub-frames by downlink control signaling. The present invention also discloses a base station in an LTE-A system. The base station includes a transmission module which is configure to trigger one or more UEs to transmit non-periodic SRSs in one or more uplink sub-frames by downlink control signaling, so that after the UE receives the downlink control signaling which is transmitted by the base station, it transmits the non-periodic SRSs in the uplink sub-frames using the non-periodic SRS resources according to the triggering of the base station. The present invention also discloses a UE in an LTE-A system. With the present invention, the resources for the non-periodic SRS can be determined, the UE channel measurement frequency can be increased, and the channel measurement requirement of the LTE-A system is better satisfied.</p> |
