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