TRANSMISSION DEVICE, RECEIVING DEVICE, TRANSMISSION METHOD, AND RECEIVING METHOD

摘要

A generation unit (10) generates, from a plurality of segments which are positioned contiguously in a frequency region, data wherein some segments are used. A first acquisition unit (14) acquires first control information whereby a segment number greater than a segment number which is used by the generated data is denoted. A second acquisition unit (16) acquires a second control signal whereby, from the segments of the segment number denoted by the first control information, only the segment which is used by the generated data is denoted as being active. An OFDM frame configuration unit (22) multiplexes the data, the first control information, and the second control information. An RF unit (28) transmits the result of the multiplexing.
