Abstract: Embodiments of the present invention disclose methods and apparatuses for receiving and sending a control channel, and are applicable to the field of communications technologies. In the embodiments of the present invention, a base station carries scheduling information of a user equipment of an R11 system in both the PDCCH region and the E-PDCCH region of a downlink subframe. In this way, the user equipment needs to detect the control channel within the PDCCH region and the E-PDCCH region, so that resources of the two regions are available to the user equipment of the R11 system. Moreover, the user equipment detects only the control channel of the first type in the PDCCH region, and detects control channels of the other type in the E-PDCCH region. The method in the embodiments of the present invention does not increase the number of control channel detections.
