1. A reference signal sending method, comprising:
sending, by a network device, a channel state information-reference signal (CSI-RS) based on a frequency-domain starting location of a resource for transmitting the CSI-RS, wherein:
the frequency-domain starting location of the resource for transmitting the CSI-RS is determined by a first resource offset between a starting resource block (RB) of a pilot region and a starting RB of system bandwidth, the system bandwidth is larger than a bandwidth part (BWP), and the pilot region is a resource that is used to transmit the CSI-RS; and
the first resource offset is greater than or equal to a second resource offset between a starting RB of the BWP and the starting RB of system bandwidth, the first resource offset is greater than 0, and the CSI-RS is transmitted on consecutive RBs within the BWP.
