1. A method for sending an uplink reference signal, comprising:
indicating, by a base station using high-layer signalling or downlink control signalling, a terminal to send an uplink reference signal in one or more sending manners; or
predefining, by both the base station and the terminal, a sending manner or resource used for sending the uplink reference signal,
wherein, the base station configures a resource pool required for a plurality of terminals to send the uplink reference signal, causing the terminal to select a resource in the resource pool to send the uplink reference signal as desired, wherein a way for the terminal to select the resource is configured by the base station or determined by the terminal according to an identity authentication ID and/or an antenna port number of the terminal.
