Abstract:
The present invention relates to precoding and feedback channel information in wireless communication system. A method includes receiving a first Precoding Matrix Index (PMI) and a second PMI from a terminal; mapping one or two codewords into layers; precoding symbols mapped into the layers using a first precoding matrix derived from the first PMI and a second precoding matrix derived from the second PMI; and transmitting the precoded symbols to the terminal, wherein the reception of the first PMI is less frequent than the reception of the second PMI.

Claim (Index 6):
A mobile terminal, comprising:\n a receiver configured to receive, from the base station, a signal; and a channel estimator configured to estimate a downlink channel from the received signal; wherein the mobile terminal is configured to transmit a first precoding matrix index (PMI) and a second PMI to the base station, wherein the receiver is further configured to receive, from the base station, precoded data symbols through an antenna, wherein the precoded data symbols are mapped into at least one layers based on a precoding matrix derived from the first PMI and the second PMI.
