ABSTRACT:
The invention relates to a method for controlling the weighting of a data signal in the at least two antenna elements of a multi-element transceiver1of a telecommunications network, which data signal is to be transmitted by at least one weighting vector from the transceiver1to a terminal2. For improving such a method, the invention comprises: receiving signals transmitted by the transceiver1at the terminal2; determining for each antenna element a value w(i) indicative of the short term variations; transmitting the values w(i) to the transceiver1; estimating, based on those values w(i), coefficients e(i) indicative of the stationary structure of the received signals; and weighting the data signal S in the antenna elements with the coefficients e(i). Alternatively, such coefficients e(i) are determined already in the user equipment2and transmitted in bursts to the transceiver1for controlling the distribution of a data signal to the antenna elements. Similar methods are proposed for soft handover.
