RADIO COMMUNICATION METHOD, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION APPARATUS

To reduce false synchronism due to false detection of a preamble signal.SOLUTION: In a radio communication method of a radio communication system performing bidirectional transmission of mobile control information between stationary radio stations and one or more mobile radio stations by using frequency hopping time division channels, the mobile radio stations synchronize timing between the radio stations via preamble signals. Between multiple stationary radio stations mutually closely located and constituting a group, frequency hopping sequences are made to be orthogonal and a same preamble signal is used, and meanwhile, between multiple stationary radio stations belonging to the respective different groups, the frequency hopping sequences are allowed to be overlapped in a part of or all of time division channels, and different preamble signals are used.SELECTED DRAWING: Figure 2 【課題】プリアンブル信号の誤検出による誤同期を低減する。【解決手段】固定無線局と移動無線局との間で周波数ホッピングする時分割チャネルを用いて移動体制御情報を双方向伝送する無線通信システムにおける無線通信方法であって、前記移動無線局は、プリアンブル信号によって、前記無線局間でタイミングを同期し、相互に近接し、グループを構成する複数の固定無線局では、周波数ホッピングシーケンスを直交させて、同一のプリアンブル信号を使用し、異なる前記グループの固定無線局間では、一部又は全ての時分割チャネルで周波数ホッピングシーケンスの重複を許容し、異なるプリアンブル信号を使用する。【選択図】図２
