Terminal device, relay device, control method, and program in wireless communication system using relay device as extension antenna of terminal device

Abstract

Provided is a terminal device in a wireless communication system including a terminal device, a base station device to which the terminal device is connected, and a relay device that converts a signal of a first frequency transmitted by the terminal device to a second frequency and amplifies and relays the signal to the base station device, and converts the signal of the second frequency transmitted by the base station device to a first frequency and amplifies and relays the signal to the terminal device. The relay device has a relay function for performing frequency conversion and amplification of a received signal and relaying the signal without performing demodulation and decoding, and a communication function for communicating with the terminal device, the communication function being different from the relay function. The terminal device acquires capability information related to the relay function of the relay device via the communication function of the relay device.
