Abstract
A wireless communication system which includes first and second wireless station apparatuses having a plurality of antenna elements and performs directivity forming. For T1 and T2 such that T2=N2×T0 and T1=N1×T2 with a predetermined period T0, the wireless communication system performs the steps of sequentially switching N1 types of directional beams at intervals of period T2 and transmitting signals while performing switching with an identical directional beam switching pattern maintained over period T1, sequentially switching N2 types of directional beams at intervals of period T0 and receiving signals over the period T1 or more while performing switching with an identical directional beam switching pattern maintained over the period T2, searching for a directional beam having a highest reception level among those acquired over a predetermined period, and setting the searched directional beam as a directional beam to be used.
