An information transmission method includes: receiving, by a terminal, a first downlink control information (DCI) used for scheduling the terminal to transmit uplink data through a physical uplink shared channel (PUSCH) in a target time unit; receiving, by the terminal, a second DCI, feedback response information of the second DCI being transmitted in the target time unit, and a time interval between a transmission time of the second DCI and a starting position of the PUSCH being not less than a preset time interval; determining a number of encoded bits of the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI; and transmitting, by the terminal according to the number of encoded bits, the uplink data and the feedback response information of the second DCI through the PUSCH in the target time unit.
