A method for sending a reference signal, comprising:

• determining a reference signal resource used for sending the reference signal;
• configuring the reference signal resource by signaling;
• and
• sending the reference signal by using the determined reference signal resources;
• wherein the reference signal resource comprises a code domain resource, and the code domain resource used for sending the reference signal is determined according to a transmission comb index of the reference signal;
• or
• the reference signal resource comprises a code domain resource, the code domain resource used for sending the reference signal is determined according to a sequence group number of the reference signal and a sequence number of the reference signal, and in a case where the sequence number of the reference signal is configured to be hopping-enabled, a sequence ID of the reference signal is used to initialize a pseudo-random sequence, or cinit=└nIDSRS/30┘·25+nIDSRS mod 30 is used as an initial value of a pseudo-random sequence;
• wherein nIDSRS is the sequence ID of the reference signal or a virtual cell ID, and mod is a modulus function.
