1. A method of data communication between two transceivers in multiple-input multiple-output radio communication system, comprising:
- simultaneously transmitting one or more data symbols corresponding to a single data stream over a plurality of transmit antennas based on independencies of the transmit antennas and priorities of the data symbols; and
receiving the data symbols through a plurality of receive antennas of a second transceiver and recovering the data stream from the received data symbols.

Abstract
In a method of data communication between two transceivers in multiple-input multiple-output radio communication system according to the present invention, a first transceiver simultaneously transmits one or more data symbols corresponding to a single data stream over a plurality of transmit antennas of a first transceiver in consideration of independencies of the transmit antennas and priorities of the data symbols, and a second transceiver receives the data symbols through a plurality of receive antennas and recovers the data stream from the received data symbols.
