Abstract

A transmission apparatus and transmitting method for signaling parameters of a part of a frame, and a reception apparatus and receiving method for decoding a part of a transmission frame. The transmitting method includes generating, using processing circuitry of a transmission apparatus, a transmission frame. The transmission frame includes a plurality of parts. A last symbol in a first one of the plurality of parts includes signaling information for decoding a second one of the plurality of parts. The transmitting method further includes transmitting the transmission frame using the processing circuitry.
