Abstract

Provided is control information related to polarizations of antennas for MISO communication. The control signal generator generates polarization information indicating whether antennas used for transmission by MISO have only a first polarization or have a second polarization as well as the first polarization. With this structure, the present invention allows for the use of combinations of SISO, MISO and MIMO, taking the polarization of antennas. Furthermore, the present invention enables the receiver to reduce the power consumption.

Claims (8)

1. A reception device comprising:

a receiver receiving, from a transmission device for Multiple-Input, Multiple-Output (MIMO) transmission, a signal containing polarization information indicating whether antennas for transmission by MIMO have only a first polarization or have a second polarization as well as the first polarization; and

a decoder decoding the polarization information contained in the signal received by the receiver, wherein

when the polarization information indicates that antennas used for transmission of transmission data have only the first polarization, the decoder stops a system for antennas having the second polarization during decoding of the transmission data.

2. A reception method for use by a reception device, comprising:

a receiving step of receiving, from a transmission device for Multiple-Input, Multiple-Output (MIMO) transmission, a signal containing polarization information indicating whether antennas for transmission by MIMO have only a first polarization or have a second polarization as well as the first polarization; and

a decoding step of decoding the polarization information contained in the signal received in the receiving step, wherein

when the polarization information indicates that antennas used for transmission of transmission data have only the first polarization, the decoding step stops a system for antennas having the second polarization during decoding of the transmission data.
