Abstract
The present invention enables an increase in data transmission performance by variously applying precoding to open and closed-loop MIMOs. An eNB in the present invention applies an identical precoder to neighboring PRBs scheduled in UE in the closed-loop MIMO, and applies an non-identical precoder to neighboring PRBs scheduled in UE in an open-loop MIMO. The UE variously introduces a precoder applied to neighboring PRBs scheduled in the UE according to whether the MIMO set in the UE is the closed-loop MIMO or the open-loop MIMO.
