Abstract

An information feedback method and apparatus are provided. The method is applicable to a terminal for which a base station configures multiple unlicensed channel resources and includes: receiving a scheduling instruction from the base station, where the scheduling instruction carries information for the terminal to determine a first transmission position for feeding back an HARQ, and the first transmission position is on a first unlicensed channel resource; obtaining the first transmission position according to the scheduling instruction, and detecting whether the first transmission position is in an available state; when detecting that the first transmission position is in a non-available state, determining a second transmission position for feeding back the HARQ, where the second transmission position is on a second unlicensed channel resource; and when detecting that the second transmission position is in the available state, sending information on HARQ feedback to the base station at the second transmission position. Therefore, the present disclosure realizes information feedback on an unlicensed channel resource and reliability of the information feedback is improved.
