Provided is a method for determining a search space of a control channel. The method comprises: determining a serial number of an enhanced physical downlink control channel (EPDCCH) set used for transmitting an EPDCCH; in accordance with the serial number of the EPDCCH set, determining a location offset of a search space corresponding to the EPDCCH set; and in accordance with the location offset of the search space corresponding to the EPDCCH set, determining the search space corresponding to the EPDCCH set. Also provided is a device for determining a search space of a control channel. By numbering time-frequency resources of EPDCCHs in groups, and determining different location offsets for different EPDCCH search spaces in accordance with the serial numbers and different cell identifiers and UE identifiers, the probability of collision of search spaces of control channels can be reduced, thereby being able to maximally use the time-frequency resources of the control channel in the case of multiple users and improve the communication efficiency.
