    Abstract: Methods and apparatuses are provided for wireless communications. Configuration information including a resource start offset is received. Downlink control information (DCI), transmitted using a first antenna port of a base station on an enhanced physical downlink control channel (EPDCCH) using at least one of control channel elements (CCEs), is received. A resource of a physical uplink control channel (PUCCH) is determined based on a first CCE of the at least one of CCEs, the first antenna port, information in the DCI, and the resource start offset in the configuration information, if a transmission type of the EPDCCH is localized transmission. A hybrid automatic repeat request acknowledgement (HARQ-ACK) signal is transmitted on the resource to the base station.

    Abstract: 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.
