US Patent 11856571 Information feedback method and apparatus

An information feedback method and apparatus are provided. The method includes: receiving a scheduling instruction from a base station that configures multiple unlicensed channel resources for a terminal, where the scheduling instruction carries information for the terminal to determine a first transmission position for feeding back a hybrid automatic repeat request (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 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 the second transmission position is in the available state, sending information on HARQ feedback to the base station at the second transmission position.
