16. A network side device, comprising:
a processor; and
a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
acquiring configuration information of a discovery reference signal, wherein the configuration information comprises time-frequency resource information and sequence information of the discovery reference signal, the time-frequency resource information indicating at least one candidate time-frequency resource location of the discovery reference signal and the sequence information indicating at least one candidate sequence of the discovery reference signal;
selecting an actual time-frequency resource location from the candidate time-frequency resource location;
selecting an actual sequence from the candidate sequence;
generating a first discovery reference signal; and
sending, through the selected actual time-frequency resource location and the actual sequence, the first discovery reference signal.
