Abstract
Provided is a wireless communication system that detects an object inside a communication area including: a base station device; and a terminal device, in which the base station device controls a timing for transmitting a reference signal for measuring a state of a propagation path on the basis of a pilot signal included in a wireless signal received from the terminal device during wireless communication and detects an object inside the communication area on the basis of propagation state information indicating a state of the propagation path received from the terminal device during wireless sensing, and the terminal device transmits, to the base station device, propagation state information measured on the basis of a reference signal received from the base station device. It is thus possible to transmit the reference signal for measuring a state of the propagation path without degrading a throughput of wireless communication.
