Title (EN) RADIO RELAY APPARATUS AND CONTROL METHOD
(FR) APPAREIL DE RELAIS RADIO ET PROCÉDÉ DE COMMANDE
(JA) 無線中継装置及び制御方法
Abstract:
(EN) A radio relay apparatus (100) is used in a wireless communication system in which a radio base station (200) transmits, at a given timing, a base station preamble signal that is a radio signal used by a radio terminal for establishing synchronization. The radio relay apparatus (100) comprises a control unit (130) that controls a service-side wireless communication unit (120S) configured to perform wireless communications with the radio terminal. The service-side wireless communication unit (120S) transmits, at a timing different from the said given timing, a relay apparatus preamble signal that is a radio signal used by the radio terminal for establishing synchronization. The control unit (130) controls the service-side wireless communication unit (120S) to transmit, at the said given timing, a preamble mask signal that is a radio signal used for disturbing the base station preamble signal.
(FR) Selon l'invention, un appareil de relais radio (100) est utilisé dans un système de communication sans fil dans lequel une station de base radio (200) transmet, à un moment donné, un signal de préambule de station de base qui est un signal radio utilisé par un terminal radio pour établir une synchronisation. L'appareil de relais radio (100) comprend une unité de commande (130) qui commande une unité de communication sans fil côté service (120S) configurée pour effectuer des communications sans fil avec le terminal radio. L'unité de communication sans fil côté service (120S) transmet, à un moment différent dudit moment donné, un signal de préambule d'appareil relais qui est un signal radio utilisé par le terminal radio pour établir une synchronisation. L'unité de commande (130) commande l'unité de communication sans fil côté service (120S) pour transmettre, audit moment donné, un signal de masque de préambule qui est un signal radio utilisé pour perturber le signal de préambule de station de base.
(JA)  無線端末によって同期の確立に使用される無線信号である基地局プリアンブル信号を無線基地局200が所定タイミングで送信する無線通信システムにおいて用いられる無線中継装置100は、無線端末との無線通信を行うように構成されたサービス側無線通信部120Sを制御する制御部130を具備する。サービス側無線通信部120Sは、上記所定タイミングと異なるタイミングで、無線端末によって同期の確立に使用される無線信号である中継装置プリアンブル信号を送信する。制御部130は、基地局プリアンブル信号を妨害するための無線信号であるプリアンブルマスク信号を上記所定タイミングで送信するようサービス側無線通信部120Sを制御する。
