Abstract:
Methods and apparatus for transmitting and obtaining uplink HARQ feedbacks are provided. The method of transmitting uplink HARQ feedbacks includes: obtaining a service priority ordered list associated with a plurality of downlink subframes; generating to-be-sent HARQ feedbacks, by bundling HARQ feedbacks associated with downlink subframes in a descending order of service priorities based on the service priority ordered list; and successively assigning uplink subframes for the to-be-sent HARQ feedbacks to transmit the to-be-sent HARQ feedbacks to a base station. With the method of transmitting uplink HARQ feedbacks provided by the present disclosure, user equipment may preferentially transmit HARQ feedbacks of subframes with low-latency to the base station. When the base station determines that the transmission of the latency-sensitive service data is faulty, the downlink subframe carrying the latency-sensitive service data is preferentially re-transmitted, thereby shortening the delivery time of the latency-sensitive service data.
