Abstract
A device controls each antenna to transmit at least one first UL pilot signal and to receive, for each first UL pilot signals DL data encoded according to the respective first UL pilot signal. The receive properties of the DL data are combined and a second UL pilot signal is determined based on the combined receive properties. The second UL pilot signal is repeatedly transmitted. The techniques may be applied in a massive multi-input multi-output scenario.
