摘要：A method and apparatus provide antenna array channel feedback. The methodcan include receiving, at a wireless terminal, a set of channel state information referencesignals. The method can include determining a precoding matrix based on the receivedset of channel state information reference signals. The precoding matrix can have arepresentation in terms of three components. The first component of the three

components can be determined from a first set of vectors. The second component of thethree components can be determined from a first set of parameters. The thirdcomponent of the three components can be determined from a second set ofparameters. The second set of parameters can be a set of unit-magnitude scalars. Themethod can include transmitting, by the wireless terminal, a representation of at leastone of the first component, the second component, and the third component.
