Abstract: The disclosure relates to a transmission device for transmitting a radio signal over a radio channel. The transmission device includes: a radio signal generator, configured to generate a radio signal in time-frequency domain; a channel state information (CSI) interface, configured to receive CSI of the radio channel; a pilot generator, configured to compose a pilot signal from at least one pre-defined pilot signal, wherein a number and a location of the at least one pre-defined pilot signal in the composed pilot signal is determined based on at least one of a latency requirement and/or the received CSI; a pilot insertion unit, configured to insert the composed pilot signal into the radio signal; and a transmission unit configured to transmit the radio signal comprising the inserted composed pilot signal. The disclosure further relates to a reception device for receiving a radio signal over a radio channel.
