Abstract
Method and device for subcarrier and antenna selection in a MIMO system. A method and device for the control of radio resources in an orthogonal frequency division multiplexing (OFMD) communication system with multiple inputs and multiple outputs (MIMO) is presented. The channel metric is calculated for each of the many transmitting antennas. Subcarriers are allocated to each of the transmitting antennas, respecting the metric rule for each of the transmitting antennas. Signals are transmitted using the subcarriers on each antenna. Adaptive encoding, modulation and transmission power control for each of the sub-carriers can be further implemented according to the metric for the channel. Power control can be exercised on the basis of each antenna, or on sub-carriers. When performing power control, a subset of transmitting antennas can be selected and the waterpouring technique can then be applied to the selected antennas. Waterpouring can be based on SNR, rather than channel response.
