Abstract

An initial signal detection method includes performing, by a user equipment, detection on one or more sub-channels on an unlicensed spectrum, and determining, based on a combination of a group common-demodulation reference signal and a group common-physical downlink control channel that is detected by the user equipment a first time, that downlink transmission has started or that a channel occupancy time has started.
