1. A cell-specific reference signal configuration method, comprising:
determining to configure a regular cell-specific reference signal in a current time slot;
determining a Synchronization Signal Block (SSB) in the current time slot based on the SSB existing in the current time slot, or determining an SSB in a previous SSB time slot before the current time slot based on an SSB not existing in the current time slot; and
indicating a modulation mode of the regular cell-specific reference signal in the current time slot using modulation mode indication information in the determined SSB, or determining the modulation mode of the regular cell-specific reference signal to be a preset modulation mode, wherein a peak-to-average ratio of the modulation mode of the regular cell-specific reference signal is less than or equal to a peak-to-average ratio of a modulation mode of data to be demodulated by using the regular cell-specific reference signal.
