<p>A data communications method using a multiple antenna which transmits parity bit data is provided to improve data transmission performance by transmitting data through different transmission antenna according to a channel state. A code block which is composed of a system bit and parity bit is transmitted through a first transmitting antenna(140). A second symbol corresponding to the parity bit is transmitted through the second transmission antenna. The re-transmission request about the code block is received. The first and the second symbol is retransmitted through the first or the second transmission antenna.</p> |
