Title:
COMMUNICATION SYSTEM, BASE STATION, AND HOST DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/196483
Kind Code:
A1
Abstract:
Provided is a highly reliable wireless communication technology. A communication system that includes a communication terminal, a plurality of base stations that can wirelessly communicate with the communication terminal, and a host device for the plurality of base stations. The host device or a serving base station for the communication terminal selects, from the plurality of base stations, a positioning base station that is to transmit a positioning signal for positioning of the communication terminal. The positioning base station transmits the positioning signal, and the communication terminal receives the positioning signal. The host device, the serving base station, or the communication terminal estimates the position of the communication terminal on the basis of the results of the reception of the positioning signal by the communication terminal. When the positioning precision required for the positioning of the communication terminal is at least a specific precision, a specific-precision positioning base state that can communicate with the communication terminal using direct waves is selected as the positioning base station (ST1450, ST1452, ST1453).
