Extension of physical downlink control signaling in a communication system

A user equipment (UE) for wireless communication, the UE comprising:

• a receiver configured to receive information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH);
• and
• a search configured to determine a starting orthogonal frequency division multiple (OFDM) symbol in which enhanced physical downlink control channel (EPDCCH) transmission starts, based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling,
• wherein the receiver is further configured to receive control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.

A method for wireless communication in a base station, comprising:

• transmitting information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) and at least one of first information on physical control format indicator channel (PCFICH) and second information on higher layer signaling;
• determining a starting orthogonal frequency division multiple (OFDM) symbol in which EPDCCH transmission starts, based on either the first information on the PCFICH or the second information on the higher layer signaling;
• and
• transmitting control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.

• a transmitter configured to transmit information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) and at least one of first information on physical control format indicator channel (PCFICH) and second information on higher layer signaling;
• and
• a selector configured to determine a starting orthogonal frequency division multiple (OFDM) symbol in which EPDCCH transmission starts, based on either the first information on the PCFICH or the second information on the higher layer signaling,
• wherein the transmitter is further configured to transmit control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.
