Abstract  Abstract

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.

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.

The embodiment of the invention claims a method for control information receiving method and device. the method for sending control information comprising: a first wireless frame on the first carrier is determined on the first subframe the first subframe comprises a control area sending control information to the user equipment on the control region of the first subframe of the first radio frame the control information comprises second sub-frame PDCCH of the first radio frame sent by the user equipment on the ePDCCH. embodiments of the present invention are not capable of transmitting control information of ePDCCH bearing on the first wireless frame when the can sending the PDCCH to the user equipment through the control region on the first subframe so as to realize uplink/downlink scheduling to the user equipment and the uplink data of the user equipment for the downlink feedback.
