1. A communication apparatus, comprising:
receiving circuitry, which, in operation, receives resource allocation control information relating to a number of clusters which is a number of frequency resources allocated to the communication apparatus, each cluster being located on a separate position from other cluster(s) on a frequency axis; and
mapping circuitry, which, in operation, determines a resource block group size of one or more frequency resources allocated to the communication apparatus based on the number of clusters indicated by the received resource allocation control information and a bandwidth that is a whole bandwidth assigned to the communication apparatus in a cell covered by a base station apparatus, wherein each of the clusters comprises one or more resource block groups of the resource block group size, and wherein the resource block group size is a number of resource blocks included in a resource block group,
wherein the resource block group size takes a larger number as the number of clusters grows larger.
