1. A communication apparatus comprising:
a receiver which, in operation, receives downlink control information including either one of first resource block assignment information that indicates resource blocks of which one allocated cluster is comprised or second resource block assignment information that indicates resource blocks of which a plurality of allocated clusters are comprised, the plurality of allocated clusters being inconsecutive in a frequency domain, and each cluster being comprised of resource blocks that are consecutive in the frequency domain; and
a transmitter which, in operation, maps uplink data to the resource blocks indicated by the first resource block assignment information or by the second resource block assignment information and transmits the mapped uplink data,
wherein the downlink control information is transmitted, from a base station, with a downlink control information (DCI) format, the DCI format having a size, which is different according to a number of codewords, a number of layers, or a number of streams and which is same, regardless of a number of clusters allocated to the communication apparatus for each number of codewords, each number of layers, or each number of streams,
wherein the DCI format has a same size according to a maximum value of the number of clusters for each number of codewords, each number of layers, or each number of streams; and
wherein a number of bits that would be used to provide the second resource block assignment information indicating the resource blocks of which the plurality of clusters are comprised is larger than a number of bits that would be used to provide the first resource block assignment information indicating the resource blocks of which the one cluster is comprised.
