Abstract:
1. A communication apparatus transmitting data using one of a first communication method and a second communication method, the communication apparatus comprising: a control unit configured to set a single parameter, in a case of transmitting the data using the first communication method, the first communication method allocating a plurality of subcarriers continuously to form a single cluster, or configured to set at least a first parameter and a second parameter in each of a first cluster and a second cluster, in a case of transmitting the data using the second communication method, the second communication method non-continuously allocating the plurality of subcarriers in at least the first cluster and the second cluster, wherein the first cluster includes a first predetermined portion of the plurality of subcarriers continuously allocated to form the first cluster and the second cluster includes a second predetermined portion of the plurality of subcarriers continuously allocated to form the second cluster; and two or more transmission antennas configured to transmit the data generated by using a single precoding in a case that one or more clusters allocated using one of the first communication method and the second communication method are included in a first region of a frequency band that is available by the communication apparatus, or configured to transmit the data generated by using a multiple precoding in a case that a part of one or more clusters allocated using one of the first communication method and the second communication method are included in the first region of the frequency band that is available by the communication apparatus, wherein the two or more transmission antennas are configured to receive first information and second information, wherein the first information indicates the set parameter and the second information indicates one of the first communication method and the second communication method, and an information amount in a case that the first information indicates the first communication method is the same as an information amount in a case that the first information indicates the second communication method.
