    摘要： Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.

    摘要： The present invention is a method in which a base station transmits a control channel signal in an orthogonal frequency division multiplexing (OFDM) communication system, wherein the method configures a physical resource block (PRB) from multiple resource elements (REs) for a control channel signal for scheduling, allocates at least one RE to a response channel signal, the at least one RE occupying the time domain the same as that of the RE used in a resource signal transmission in a data channel region of the PRB and occupying the frequency domain nearest to the RE used in the reference signal transmission, and transmits the control channel signal for scheduling and the response channel signal.
