Abstract
The present application relates to methods for operating a terminal device () and a base station () of a cellular wireless multiple-input and multiple-output, MIMO, system (). An uplink precoding for transmitting uplink signals from a plurality of antenna elements () of the terminal device () to the base station () is determined. An uplink pilot signal using the uplink precoding and a radio resource of a transmission frame of the MIMO system is transmitted from the plurality of antenna elements (). At the base station (), a downlink precoding and uplink receive parameters are adjusted based on a receive property of the precoded uplink pilot signal from the terminal device ().
