Abstract: Embodiments of the present invention relate to the technical field of communications, and provide a resource mapping method and device, which can ensure correct transmission, on a PRB, of data mapped on a VRB. The specific solution comprises: a network device writes n physical resource block groups row by row into an interleaving matrix, N null values being inserted into the intersections between the first row and the last N columns of the interleaving matrix or the intersections between the last row and the first N columns of the interleaving matrix, n being a positive integer, and N being a natural number; read the n physical resource block groups from the interleaving matrix column by column, the read n physical resource block groups having a mapping relationship with n virtual resource block groups; and determine, according to the n physical resource block groups having a mapping relationship with the n virtual resource block groups, a physical resource block mapped to a virtual resource block in the n virtual resource block groups. The embodiments of the present application are used for resource mapping.
