Disclosed are a method and an apparatus for transmitting ACK/NACK feedback information. By applying the technical solution of the present invention, when ACK/NACK feedback information is transmitted based on an ACK/NACK mapping table with a PUCCH format 1b with channel selection scheme, the problem of inconsistent detection results due to inconformity of the transmission scheme by a base station and a user equipment (UE) in the process of feeding back the ACK/NACK feedback information can be avoided, so as to implement a rollback of LTE Rel-8 PUCCH format 1a/1b.
