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 1):
A method for transmitting control information of a terminal, the method comprising:\n estimating a downlink channel from a signal received from a base station; transmitting a first precoding matrix index (PMI) to the base station; transmitting a second PMI to the base station; and receiving, 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.
