ABSTRACT:
A wireless communication apparatus wherein the throughput is improved. In a wireless communication apparatus (100), a frame generating part (120) adds a header to a data portion to form a transport frame. A control part (190) acquires a variation index in a propagation path and decides the length of the data portion of the transport frame in accordance with the propagation path variation index. In this way, when the propagation path variation index is large, that is, the degree of propagation path variation is high, the data portion can be shortened. Contrarily, when the propagation path variation index is small, that is, the degree of propagation path variation is low, the data portion can be elongated. Thus, when the degree of propagation path variation is high and hence the probability of reception of a retransmission request from a receiving end is high, the data portion can be shortened to prevent a degradation of the throughput that would occur due to a transmission of long data. Contrarily, when the probability of reception of a retransmission request is low, a long data can be transmitted to improve the throughput.
