METHOD FOR SENDING ENHANCED PHYSICAL DOWNLINK CONTROL CHANNEL (EPDCCH), BASE STATION, AND TERMINAL

摘要

Embodiments of the present invention relate to a method for sending an enhanced physical downlink control channel (ePDCCH), a base station, and a terminal. Physical resources one ePDCCH is mapped to comprise at least one control channel component member; one physical resource block pair can be used for sending at least two control channel component members, and can be divided into at least two areas, and comprised REs are respectively corresponding to at least two control channel component members; the at least two control channel component members respectively have different numbers of control channel component members; and the number of a control channel component member corresponding to at least one RE in one area of the at least two areas has a one-to-one mapping relationship with the number of a control channel component member corresponding to an RE in at least another area of the at least two areas; a base station determines an RE corresponding to a control channel component member in the physical resource block; and the base station sends control information borne by the control channel component member through the RE corresponding to the control channel component member in the physical resource block.
