Abstract:
1. An apparatus, comprising: a mobile station, including at least two antennas, wherein the mobile station is configured to determine a first channel quality feedback value based on signals received from a base station via the antennas of the mobile station; and a measuring unit disposed in close spatial proximity to the mobile station, including a processing device and at least two antennas, wherein the processing device is configured to determine an orthogonality of signals received from the base station via the antennas of the measuring unit, to determine a second channel quality feedback value based on the determined orthogonality having a significantly higher precision than the first channel quality feedback value, and to determine a quality of the channel quality feedback value of the mobile station by comparing the determined second channel quality feedback value with the first channel quality feedback value of the mobile station.
