Abstract

The embodiment of the invention discloses a retransmission feedback method, a network device, a terminal device, and a computer-readable storage medium. The method includes that a terminal device receives a target code block group (CBG) sent by a network device, wherein the target CBG is a part of CBG in a target transmission block (TB); the terminal device generates feedback information accordingto the decoding situation of the target CBG, wherein the feedback information includes a TB retransmission indication domain that indicates whether the target TB needs to be retransmitted; and the terminal device sends the feedback information to the network device. In the embodiment of the invention, the terminal device, when needing to feed back the target CBG sent by the network device, indicates whether the target TB corresponding to the target CBG needs to be retransmitted according to the TB retransmission indication domain included in the feedback information. The method solves a problem that the terminal device cannot or cannot quickly instruct the network device to retransmit the target TB when using a CBG-based HARQ feedback way.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a retransmission feedback method, network equipment, terminal equipment and computer-readable media. Background technique [0002] With the commercialization of the fourth-generation mobile communication technology (4G) and the continuous growth of mobile services, research on the fifth-generation communication technology (5G) has begun worldwide. 5G is a multi-technology fusion communication that meets the needs of a wide range of data and connection services through technological change and innovation. The third generation partnership project (Third Generation Partnership Project, 3GPP) has established a research project (study item, SI) on 5G new air interface research. According to 5G's division of vertical scenarios, 3GPP mainly conducts research on new air interface technology from three aspects: enhanced wireless broadband (enhanced mobile broadband, eMBB),...
