CONTROL INFORMATION SENDING METHOD, RECEIVING METHOD, AND APPARATUS

摘要

An embodiment of the present invention provides a control information sending method, receiving method, and apparatus. Said control information sending method comprises: determining a first subframe of a first wireless frame on a first carrier, said first subframe comprising a control region; sending control information to user equipment by means of said control region of the first subframe of the first wireless frame, said control information comprising a PDCCH; sending an ePDCCH to said user equipment by means of a second subframe of said first wireless frame. The embodiment of the present invention can send a PDCCH to user equipment by means of the control region of the first subframe when the control information carried by an ePDCCH cannot be sent on the first wireless frame, therefore enabling uplink/downlink scheduling for the user equipment as well as downlink feedback for the uplink data from user equipment.
