<p>A wireless base station device (1) transmits a directive multi-beam on a downstream physical channel between itself and a wireless terminal device (3). This wireless terminal device (3) receives the directive multi-beam, determines a correlation to its own orthogonal code series on each orthogonal code series of the directive multi-beam received, determines the orthogonal code series of the highest self-correlation, and notifies the wireless base station device (3), of the orthogonal code series discrimination information for discriminating that orthogonal code series by using an upward physical channel. As a result, it is possible to make the time period, for which the wireless base station device (1) recognizes the orthogonal code series of the highest self correlation in the wireless terminal device (3) and the excellent reception state, drastically shorter than that of the prior art. Therefore, the loop control between the wireless base station device (1) and the wireless terminal device (3) can be highly speeded up, thereby to improve the throughput of the channel to transmit the user data, drastically.</p> |
