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.

Abstract: Embodiments provide a communication method, a network side device, and a terminal device. When a quantity of minimum scheduling time units in one time of scheduling performed by a network side device is S, and the network side device and a terminal device transmit data in a first transmission mode, a target scheduling rule can be determined by the terminal device from N scheduling rules. The scheduling rule includes at least one of a quantity T of transport blocks in one time of scheduling and a mapping relationship between T transport blocks and S minimum scheduling time units in one time of scheduling. The first transmission mode is a single-antenna transmission scheme or a multi-antenna transmission scheme. Communication can be performed, by the network side device, with the terminal device according to the target scheduling rule. In this way, proper scheduling rules can be selected to adapt to different scenarios.

Abstract: A feedback method is provided, including receiving, by a first device, data sent by a second device, and sending, by the first device to the second device, feedback information indicating whether the data is successfully received. In this method, a quantity of bits of the feedback information is associated with a size of a transmission time unit in a communications system. By using the foregoing method, the quantity of bits of the feedback information is determined based on the size of the transmission time unit. This implements a compromise between transmission efficiency and feedback overheads in the communications system.
