Patent ID: 8767629

Claim:
A method for triggering a terminal to send a sounding reference signal, comprising: configuring at least two preset resource patterns for the terminal through higher-layer signaling, wherein multiple types of resource information are preset in each resource pattern of the at least two preset resource patterns to indicate a resource; obtaining requirement information of measurement, wherein the requirement information comprises a position and a bandwidth of a frequency hand to be measured; selecting a resource for the terminal in the at least two preset resource patterns according to the requirement information; and sending a triggering Physical Downlink Control Channel (PDCCH) to the terminal on a trigger subframe, so as to trigger the terminal to utilize the selected resource to send the sounding reference signal, wherein the trigger subframe is for indicating, to the terminal, a subframe to which the selected resource is applied; wherein the higher-layer signaling is based on a higher layer than the triggering PDCCH.
