Mobile terminal stations utilizing wireless local area network (WLAN) devices have recently increased. Hence, packet collisions due to interfering signals have become an important issue. WLANs detect collisions when the acknowledgment (ACK) frame is not returned. This considerably reduces the WLAN transmission efficiency. This paper proposes a retransmission control scheme utilizing multiple input multiple output (MIMO) transmission, in which collisions may be detected during signal transmission. We evaluated and analyzed the effectiveness of the proposed scheme through computer simulations and theoretical analysis. The theoretical analysis agree with the computer simulation results, indicating the efficiency and reliability of our proposed scheme.
