Configuration method and system for measuring reference signal

The invention discloses configuration method and system for measuring a reference signal, realizing the configuration of non-periodic SRS (Software Requirements Specification) and solving the problem that UE (User Equipment) can not dynamically and flexibly send out the non-periodic SRS in the prior art. The configuration method comprises the following steps of: sending out downstream control information to UE by a base station; and triggering the UE to send out the non-periodic SRS through the downstream control information and indicating a resource used by the UE for sending out the non-periodic SRS.
