    Abstract: This application provides a resource mapping method and a device. A network device writes n physical resource block groups into an interleaving matrix row by row, where N null values are inserted into intersections between the first row and the last N columns of the interleaving matrix or intersections between the last row and the first N columns of the interleaving matrix, n is a positive integer, and N is a natural number; reads the n physical resource block groups from the interleaving matrix column by column, where the n read physical resource block groups are mapped to n virtual resource block groups; and determines, based on the n physical resource block groups mapped to the n virtual resource block groups, physical resource blocks mapped to virtual resource blocks in the n virtual resource block groups.

    Abstract: A resource configuration method, an apparatus, and a system are disclosed. The method includes: determining a reserved resource element (RE) in a resource unit, where the reserved RE is included in a reserved resource; and transmitting data on all or some REs other than the reserved resource. The resource unit includes X resource blocks (RBs) in frequency domain and includes Y symbols in time domain, where X and Y are positive integers. According to the resource configuration method provided in the present disclosure, a data conflict between different terminals during data transmission can be reduced, and resource utilization can be improved.

    Abstract: A communication method and a communications apparatus are provided. The method includes: sending, by a network device, indication information to a terminal, where the indication information is used to indicate at least one second BP associated with a first BP; and performing signal transmission, by the network device, with the terminal on the first BP and the at least one second BP. It may be learned that the network device indicates, to the terminal by using the indication information, the at least one second BP associated with the first BP, so that the network device and the terminal can transmit signals on BPs that are associated with each other. In addition, there may be a plurality of second BPs associated with the first BP.
