发明名称 Method for testing the transmission modes of a radio device
摘要 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.

主权项 1. A method for testing a device for wireless communication, including the following steps: establishing a channel quality of a transmission channel for transmitting data in this channel through a test device, wherein the established channel quality is particular to a transmission state out of plural transmission states and is particularly chosen to such a value that tests switching processes between transmission states, wherein the channel quality is adjusted by the test device such that it is located at or in a distance above or below a switching point Ui between two transmission states, and wherein the distance is in the order of magnitude of the error of a corresponding channel quality determination of the device to be tested; transmitting data from the test device to a device to be tested using the established channel quality; evaluating the data transmitted using the established channel quality in the device to be tested for determining at least one item of decision information; sending a response signal containing the at least one item of decision information back to the test device; allocating the at least one item of decision information obtained from the response signal to a transmission state to be adjusted, wherein precisely one transmission state is unequivocally allocated to each total content of obtained items of decision information; determining an expected transmission state corresponding to the established channel quality used for transmission; and comparing the expected transmission state to the transmission state to be adjusted, wherein the transmission state to be adjusted is used for further transmission of data.
