The invention discloses a transmission method for feedback information in uplink transmission and equipment. The method comprises the steps as follows: a terminal sends a physical uplink shared channel PUSCH in a special sub-frame m, wherein m is an integer; the terminal detects a downlink control channel using an uplink and downlink control information DCI format in a sub-frame or sub-frame m+k including downlink transmission resources after the special sub-frame m, wherein k is a positive integer; and the terminal determines whether to retransmit the PUSCH transmitted in the special sub-frame m according to the downlink control channel. Therefore, a transmission scheme for the feedback information of the PUSCH transmitted in the special sub-frame is provided, and thus the condition that the PUSCH transmitted in the special sub-frame can normally acquire ACK/NACK feedback information is ensured.
