CODEBOOK FOR EIGHT TRANSMIT ANTENNAS AND MULTIPLE INPUT MULTIPLE OUTPUT COMMUNICATION SYSTEM USING THE CODEBOOK

摘要

A transmitter and a receiver of a multiple input multiple output (MIMO) communication system may use two codebooks to share channel information. When the transmitter uses eight transmit antennas, two codebooks may be defined. When the receiver generates two precoding matrix indicators from two codebooks, a combination of the two precoding matrix indicators may indicate a single precoding matrix. Precoding matrix candidates may also be defined.

1. A communication method of a receiver, the communication method comprising:
determining a first precoding matrix indicator (PMI) indicating a first codebook and a second precoding matrix indicator (PMI) indicating a second codebook; and transmitting, to a transmitter, the first and the second PMIs as a feedback information, wherein a precoding matrix is configured to be determined using the first and the second PMIs.
