  • Method for testing the transmission modes of a radio device
    Patent number: 9363035
    Abstract: A method for determining a channel quality for the transmission of data in the channel by a test device. The test device transmits the data with the determined channel quality to a device to be tested which determines one or more pieces of decision information. The device to be tested forwards the piece(s) of decision information to the test device as a response signal and the test device reads the piece(s) of decision information from the response signal. The piece(s) of decision information from the response signal is/are uniquely attributed to a transmission mode to be adjusted. The initially determined channel quality is also uniquely attributed to an expected transmission mode. The expected transmission mode is compared with the transmission mode to be adjusted in a comparative unit in the evaluation unit, thereby allowing a statement regarding the correctness of the transmission mode to be adjusted.
