Abstract
A hybrid automatic repeat request (HARQ) feedback method is applied to a terminal, wherein a base station allocates to the terminal multiple available scheduling resources configured to provide Early Data Transmission (EDT) service. The method includes: selecting an available scheduling resource from the multiple available scheduling resources; sending EDT data to the base station on the selected available scheduling resource; determining a HARQ feedback time point for the EDT data according to a preset rule; and when HARQ information sent by the base station is received at the HARQ feedback time point, determining a transmission result of the EDT data based on the HARQ information.
