Abstract: A wireless communication system comprising a plurality of base station devices including a first base station device and a second base station device, wherein the first base station device connected with a terminal determines whether to continue connection with the terminal or not on a basis of a communication quality requirement of the terminal and a resource that can be provided to the terminal, and the first base station device transmits a control signal instructing connection with the second base station device to the terminal in a case where the first base station device determines not to continue the connection with the terminal.

Abstract: A spatial image generation apparatus includes: a propagation channel information measurer that measures propagation channel information of a target area from radio signals delivered between transmitting and receiving stations; a learned model generator that generates a learned model for generating a spatial image of the target area from the newly input propagation channel information using the propagation channel information and image information obtained by imaging the target area with a camera; and an image generator that generates the spatial image of the target area by inputting the propagation channel information newly input from the propagation channel information measurer to the learned model. The object detection apparatus includes: the spatial image generation apparatus; and an object detector that detects an object in the target area from the spatial image generated by the image generator using an image analysis method.

Abstract: A radio communication method includes: a transmitting step of broadcasting, by a radio base station, a connection condition of the radio base station; a managing step of managing, by the radio base station, a connection with a radio station requesting a connection to the radio base station based on the connection condition, by using a blockchain shared by a plurality of radio base stations; and a changing step of acquiring, by the radio base station, information on a radio station connected to another radio base station from the blockchain and changing the connection condition of the radio base station based on the information on the radio station connected to the other radio base station.
