The present invention discloses a control information transmission method, user equipment, and a base station, and belongs to the field of wireless technologies. The method includes: acquiring, by user equipment, configuration information of an enhanced physical downlink control channel EPDCCH set; determining, by the user equipment according to the configuration information and from the EPDCCH set, at least one EPDCCH set in which an EPDCCH needs to be monitored; and monitoring, by the user equipment, an EPDCCH on a resource corresponding to the at least one EPDCCH set, to acquire control information sent by a base station. In the present invention, because the at least one EPDCCH set is only a part of EPDCCH sets corresponding to EPDCCH common search space, and this part may be monitored by users that have different capabilities in a system, common control information that needs to be detected by all the users may be sent on this part of the EPDCCH sets; therefore, repetitious sending of the common control information can be avoided, control signaling overheads can be reduced, and spectrum utilization can be improved. |
