RADIO COMMUNICATION SYSTEM, CONTROL DEVICE, RADIO COMMUNICATION METHOD AND PROGRAM

To shorten, without using an external sensing device, time in which radio communication quality is deteriorated.SOLUTION: A radio communication system includes one or more first radio communication devices, and one or more second radio communication devices. The first radio communication device includes: a radio communication part configured to form abeam and performing radio communication with the second radio communication device; and a beam control part for controlling the beam. The second radio communication device is configured to: receive reference signals that the beam control part controls the radio communication part to transmit respectively via a plurality of kinds of the beams; and inform of transmission information indicating information regarding radio transmission of the received reference signals. The first radio communication device or a control device includes: an estimation prediction part for estimating or predicting, using the received transmission information, a propagation environment or future communication quality between the first radio communication device and the second radio communication device; and a control part for controlling the radio communication between the first radio communication device and the second radio communication device based on the estimation or prediction result.SELECTED DRAWING: Figure 1 【課題】外部センシング機器を用いることなく、無線通信の品質が低下している時間を短縮する。【解決手段】無線通信システムは、１以上の第１無線通信装置と、１以上の第２無線通信装置とを有する。第１無線通信装置は、ビームを形成して第２無線通信装置と無線通信する無線通信部と、ビームを制御するビーム制御部とを備える。第２無線通信装置は、ビーム制御部の制御により無線通信部が複数種類のビームそれぞれにより送信した参照信号を受信し、受信した参照信号の無線伝送に関する情報を示す伝送情報を通知する。第１無線通信装置又は制御装置は、受信した伝送情報を用いて第１無線通信装置と第２無線通信装置との間の伝搬環境又は将来の通信品質を推定又は予測する推定予測部と、推定又は予測の結果に基づいて第１無線通信装置と第２無線通信装置との間の無線通信を制御する制御部とを備える。【選択図】図１
