Abstract

The embodiment of the invention discloses a retransmission feedback method, a related device, and a computer-readable medium. The method comprises: at least two transport blocks (TB) sent by a data sending device are received; the at least two TBs are decoded to generate hybrid automatic repeat request (HARQ) feedback information, wherein the HARQ feedback information includes first indication information and second indication information, the first indication information is used for indicating whether the at least two TBs are received correctly, if a first TB exists in the at least two transmission blocks TB, the second indication information is used for indicating whether all code block groups (CBG) in a second TB are received correctly, the first TB is configured to carry out transporting and feedback by using the CBG as a unit and the second TB belongs to the first TB; and the HARR feedback information is sent to the data sending device. Therefore, when HARQ-ACK feedback processingis carried out, a bit number of the HARQ-ACK feedback information is reduced effectively, so that the resource utilization rate is increased and the system performances are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a retransmission feedback method, related equipment and computer-readable media. Background technique [0002] In the research phase (SI, Study Item) of the New Radio (NR), the enhanced Hybrid Automatic Repeat Request (HARQ) function that can potentially provide greater spectrum efficiency is studied. One of the enhancement methods is to support multiple acknowledgment (Acknowledgment, ACK) bit feedback for each transport block (Transport Block, TB). [0003] In a Long Term Evolution (LTE) system, one TB includes multiple code blocks (CodeBlock, CB), but one TB uses only one HARQ-ACK bit feedback. When the received TB is not decoded correctly, even if only one of the CBs has data errors, the data of the entire TB should be retransmitted. In the NR system, the amount of data contained in a TB or the number of CBs will increase exponentially compared with LTE. If t...
