Abstract
A method for mobile telecommunication includes receiving in a mobile communication terminal downlink signals from at least first and second cells that coordinate transmission of the downlink signals with one another. Channel feedback is calculated in the terminal based on the received downlink signals. The channel feedback is configured to enable the first cell to precode a first signal destined for the terminal in response to the channel feedback with a first precoding vector, and to enable the second cell to precode a second signal destined for the terminal in response to the channel feedback with a second precoding vector that differs in magnitude from the first precoding vector. The first and second signals convey same data. The channel feedback is transmitted from the terminal. Calculating the channel feedback includes calculating one or more of a single-user Channel Quality Indicator (CQI), a multi-user CQI, and a non-cooperative-transmission CQI.
