The present invention relates to a method of transmitting configuration information, a method of detecting control channel resources, and devices therefor. The transmission method comprises: configuring, for each coreset, control channel resources on a time unit of a scheduling unit (SU); transmitting configuration for the resources of control channel on the time unit of the SU, wherein control channel resources belong to the coreset containing a plurality of continuous or discontinuous frequency-domain physical resource blocks available to transmit a downlink control channel. The detection method comprises: receiving configuration for the resources of control channel on a time unit of an SU; performing blind detection of a downlink control channel for a user on the time unit of the SU according to the configuration information. The present invention can flexibly configure control channel resources and reduce blind detection of a control channel by a terminal, thereby attaining reduction of power consumption caused by blind detection of the control channel by the terminal and load equalization.
