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 of this application provide a multi-carrier scheduling method. A network device configures first DCI for scheduling a plurality of carriers, to reduce PDCCH resource overheads. In addition, when the network device configures the first DCI and other DCI (for example, second DCI), monitoring bit lengths of the two pieces of DCI are aligned, to obtain a monitoring bit length for blind detection. This can reduce blind detection complexity of blind detection performed by a terminal device on DCI, and improve system transmission performance.

Abstract: A downlink transmission method includes determining a time domain position of at least one first transmission resource in resources of a downlink data channel. When the at least one first transmission resource is a plurality of first transmission resources, start positions of time domain positions of the plurality of first transmission resources are the same. The at least one first transmission resource can be used to transmit downlink control information. The method also includes determining, based on the time domain position of the at least one first transmission resource and time domain positions of the resources of the downlink data channel, a condition satisfied by the at least one first transmission resource. The method further includes determining a transmission mode of the downlink control information and/or the downlink data channel in the resources of the downlink data channel based on the condition.
