Abstract: The application relates to a communication device comprising: a communication interface configured to transmit a pilot signal via a communication channel to a second communication device and to receive a plurality of data elements representing channel state information (CSI) from the second communication device, wherein the plurality of data elements are a subset of a set of data elements representing the full channel state information (CSI) being available at the second communication device; and a processing unit configured to generate the full channel state information (CSI) on the basis of the plurality of data elements by applying a fitting scheme to the plurality of data elements received from the second communication device.

Abstract: A full duplex radio unit comprising a transmission unit, an antenna, a reception unit, a circulator and a power reduction unit is provided. The transmission unit is adapted to generate a first signal. The circulator is adapted to provide the first signal from the transmission unit to the antenna. The antenna is adapted to transmit the first signal and simultaneously receive a second signal using an identical frequency or frequency band. The circulator is adapted to provide a third signal to the power reduction unit, wherein the third signal comprises the second signal and interference generated from the first signal by the antenna and the circulator. The power reduction unit is adapted to reduce the power of the third signal by multiplying the third signal by factor of √ρ, wherein ρ is between zero and one, thereby generating a fourth signal.
