Claim Text:
1. A method of receiving a downlink shared channel signal at a user equipment (UE) configured to operate in a closed loop multi input multi output (MIMO) scheme, the method comprising: reporting first information indicating first precoding weights to a base station, the first precoding weights being UE preferred precoding weights for use in multiplication with downlink data; receiving second information indicating second precoding weights from the base station after the first information is reported, wherein the second precoding weights are determined in consideration of the first information and multiplied to data of the downlink shared channel signal; decoding the downlink shared channel signal using the second precoding weights when the second weights are different from the first precoding weights; and decoding the downlink shared channel signal using the first precoding weights when the second precoding weights are identical to the first precoding weights.
