Abstract
Example reference signal sending methods and apparatus are described. In one example method, a terminal device detects whether a paging scheduling message exists in a PDCCH search space whose starting subframe is a subframe corresponding to a paging occasion (PO), and/or detects whether a wake-up signal (WUS) exists before a PO. A network device determines a time domain resource in first duration based on a quantity of paging occasions in a discontinuous reception period, where the time domain resource is a time domain resource in a time-frequency resource used to transmit a reference signal. The network device sends the reference signal to a terminal device on the time domain resource.
