Abstract
A method of retransmitting packet data in a wireless communication system comprises receiving a link map information element from a transmitting station having three antennas to achieve space time transmit diversity, wherein first, second and third packet data are transmitted from first, second and third antenna of the transmitting station, respectively. The method also comprises transmitting a non-acknowledgement signal to the transmitting station if at least one packet data from the transmitting station is not properly decoded. The method also comprises receiving the packet data from the transmitting station, wherein at least two or retransmitted packet data are transmitted from different antennas of the transmitting station, and one of retransmitted packet data is transmitted from the same antenna of the transmitting station. The retransmitted packet data are received with an information element comprising a retransmission count associated with a number of retransmission made by the transmitting station.
