Abstract
A method, a receiver and computer program product for reporting at least one channel quality indicator from a receiver to a transmitter in a MIMO system are disclosed herein. In one embodiment, the receiver receives one or more data streams transmitted by the transmitter wherein the data streams are processed by the transmitter using a transmission precoding matrix W prior to transmission to the receiver. The receiver estimates a preferred precoding matrix Wwhich is preferred by the receiver and processes the received data streams using the transmission precoding matrix W, such that the effective channel G at the output of the signal processing module is dependent upon the transmission precoding matrix W used by the transmitter. The receiver determines a second effective channel G, uses it to determine the at least one channel quality indicator and transmits the determined at least one channel quality indicator to the transmitter.
