Abstract: A data sending solution based on a maximum latency constraint T is provided. A transmitting end sends (T+B) data blocks, where first T data blocks are original data blocks, last B data blocks are B encoded data blocks, and a quantity of encoded data packets in the encoded data block is flexible and controllable. A receiving end only needs to perform joint decoding on a specific quantity of encoded data packets and a correct data packet in an incorrect data block, to recover an incorrect data packet in the incorrect data block. The solution in this application can meet a requirement of a maximum latency T, and can reduce a quantity of encoded data packets. The solution may be applied to an XR service or another service that has a low-latency requirement.

Abstract: This application provides a data sending method and a communication apparatus. The method includes: A first node determines, based on a quality of a channel between the first node and a second node, a sending time for starting to send data, where the first node is one of several candidate previous-hop nodes of the second node. The first node starts to send the data to the second node at the sending time. According to the data sending method, when a node needs to send data to a next-hop node of the node, the node may determine, based on quality of a channel between the node and the next-hop node of the node, a sending time for starting to send the data.

Abstract: Various embodiments provide a data communication method. Under the method, a transmit end maps each code block group CBG in N CBGs to each layer in a corresponding layer group based on a correspondence between the N CBGs and N layer groups. Each layer group includes at least one layer, and N is a positive integer. The transmit end then sends data to a receive end. T transport block corresponding to the data includes the N CBGs. In this way, a mapping relationship between a CBG and a layer group is established by grouping layers, so as to improve data reception quality, through interference cancellation, for transmission among different layer groups, and ensure adaptivity to a CBG-based retransmission feedback, thereby optimizing transmission performance of an entire communications system.
