CHANNEL FEEDBACK FOR COOPERATIVE MULTIPOINT TRANSMISSION

摘要

A method 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 cause the first cell to precode subsequent downlink signals in response to the channel feedback with a first precoding vector, and to cause the second cell to precode the subsequent downlink signals in response to the channel feedback with a second precoding vector that differs in magnitude from the first precoding vector. The channel feedback is transmitted from the terminal.
