Method for controlling the data signal weighting in multi-element transceivers and corresponding devices and telecommunications network

A method for controlling the weighting of a data signal in the at least two antenna elements of a multi-element transceiver of a telecommunications network, which data signal is to be transmitted by at least one weighting vector from the transceiver to a terminal, and which antenna elements form at least two transmit paths to the terminal, the method comprising:

• transmitting signals via each transmit path to the terminal;
• receiving from the terminal a determined set of coefficients for each transmit path in a burst, the set of coefficients being indicative of a dominant stationary structure in the signals received at the terminal;
• and
• controlling the weighting of a data signal in the antenna elements of the transceiver with the coefficients.

An apparatus comprising:

• a transmission component configured to cause a transmission of signals via at least two transmit paths to a terminal, the at least two transmit paths being formed by at least two antenna elements of a multi-element transceiver;
• an estimating component configured to estimate coefficients indicative of the stationary structure of the signals received by the terminal based on values indicative of the short term variations of the signals for each transmit path received from the terminal;
• and
• a weighting component configured to weight the data signal in the antenna elements with the coefficients.

An apparatus comprising:

• a reception component configured to receive signals transmitted by a multi-element transceiver via at least two transmit paths, the at least two transmit paths being formed by at least two antenna elements of the transceiver;
• a determination component configured to determine a set of coefficients for each transmit path indicative of a dominant stationary structure in the received signals;
• and
• a transmitting component configured to cause a transmission of the coefficients to the transceiver in a burst for enabling the transceiver to control the weighting of a data signal in the antenna elements of the transceiver with the coefficients.
