HARQ-ACK SIGNAL TRANSMISSION IN RESPONSE TO DETECTION OF CONTROL CHANNEL TYPE IN CASE OF MULTIPLE CONTROL CHANNEL TYPES

摘要

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

1. A method for wireless communications, the method comprising:
receiving configuration information comprising a resource start offset and information for a transmission type of an enhanced physical downlink control channel (EPDCCH); receiving downlink control information (DCI) transmitted 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 CCEs, information in the DCI, and the resource start offset in the configuration information if the transmission type of the EPDCCH is distributed transmission; and transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) signal on the resource to the base station.
