1. A method for wireless communications, the method comprising:transmitting configuration information comprising a resource start offset and information for a transmission type of an enhanced physical downlink control channel (EPDCCH);
transmitting, to a user equipment (UE), downlink control information (DCI) using at least one antenna port of a base station on the EPDCCH using at least one of control channel elements (CCEs);
determining a resource of a physical uplink control channel (PUCCH) based on a first CCE of the at least one of the CCEs. information in the DCI, and the resource start offset in the configuration information, in response to the transmission type of the EPDCCH being distributed transmission; and
receiving a hybrid automatic repeat request acknowledgement (HARQ-ACK) signal on the determined resource.
