PROBLEM TO BE SOLVED: To provide a method for determining a control channel resource used to feed back uplink ACK/NACK information.SOLUTION: A downlink control channel for carrying scheduling information of a downlink data channel, which is transmitted by a base station, is formed by at least one control channel logic element, the at least one control channel logic element is mapped at at least one antenna port, and a first control channel resource is determined according to at least one of the sequence number information of the first control channel logic element and at least one of an offset and antenna port information of the first antenna port corresponding to the first control channel logic element of the downlink control channel which is successively detected. The first control channel resource is used to feed back acknowledgement (ACK)/non-acknowledgement (NACK) regarding the downlink data channel.SELECTED DRAWING: Figure 3 |
