TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEIVING DEVICE AND RECEIVING METHOD

摘要

Provided is a frame configuration usable for both SISO transmission and MISO and/or MIMO transmission. A frame configurator of a transmission device configures a frame by gathering data for SISO and configures a frame by gathering data for MISO and/or MIMO data, thereby to improve the reception performance (detection performance) of a reception device.

1. A transmission device having a function of performing transmission by single-input single-output (SISO) as well as either one or both of multiple-input single-output (MISO) and multiple-input multiple-output (MIMO), the transmission device being configured to:
transmit, by MISO, at a same frequency and a same time, among PLP data transmitted by physical layer pipes (PLPs), a modulated signal modulated by a first PLP data for MISO and a modulated signal modulated by a second PLP data for MISO that is different from the first PLP data for MISO; transmit, by MIMO, at a same frequency and a same time, among PLP data transmitted by PLPs, a modulated signal modulated by a first PLP data for MIMO and a modulated signal modulated by a second PLP data for MIMO that is different from the first PLP data for MIMO; and transmit, by SISO, at a same frequency, at a same time, and at different transmission powers that match transmission powers used in either or both of MISO and MIMO, among PLP data transmitted by PLPs, a modulated signal modulated by PLP data for SISO.
