METHOD FOR PERFORMING PRECODING FOR ADAPTIVE ANTENNA SCALING IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR |
| 摘要 |
A method for transmitting a signal to a receiver by a transmitter in a wireless communication system is disclosed. The method includes mapping one or more transmission steams to first logical antenna ports, mapping signals mapped to the first logical antenna ports to second logical antenna ports, and mapping signals mapped to the second logical antenna ports to physical antennas to transmit the signals mapped to the physical antennas to the receiver, wherein the number of the first logical antenna ports is less than or equal to the number of the second logical antenna ports and varies with a channel state between the transmitter and the receiver. |
