Abstract
A receiver is configured to receive and process a radio signal. The radio signal includes a first frequency band including a first signal, the first signal including a plurality of TDD-frames. The receiver is configured to evaluate reception of downlink data to obtain evaluation data. The receiver is further configured to transmit the evaluation data in a second frequency band outside of the first frequency band.
