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.
