## Abstract

The application provides a method, apparatus for transmitting HARQ-ACK information, electronic device and storage medium. The method includes: determining, by a terminal, a TU in which a PUCCH transmitting the HARQ-ACK is located according to a length of the time slot in which the PUCCH transmitting the HARQ-ACK is located and the number of PUCCHs in the time slot; transmitting, by the terminal, the HARQ-ACK information based on the determined TU in which the PUCCH transmitting the HARQ-ACK is located and a corresponding HARQ timing relationship.
