1. A method for reference signal sending, performed by a transmitter, comprising:
determining a time-frequency resource pattern of a target reference signal used for interference measurement, wherein the time-frequency resource pattern is used to indicate a time domain location and a frequency domain location of the target reference signal; and
sending the target reference signal by using zero power or non-zero power based on the time-frequency resource pattern,
wherein the target reference signal is located on a symbol occupied by a data signal.
