In a scheduling method, a first device configures a blind detection parameter of a control channel based on a carrier type or a carrier group; or separately configures a blind detection period for different carriers; or configures a blind detection period for a USS and a CSS of a control channel; or configures a blind detection period for different downlink control information DCI; and then, sends configuration signaling that carries the blind detection parameter (which may include the blind detection period), where the blind detection parameter is used by a second device to perform blind detection on the control channel.
