Communication terminal device and communication system

An extended reality (XR) communication terminal device having an optically transmissive display mounted thereon, the XR communication terminal device comprising:

• first and second radio-frequency signal processing modules configured to perform radio-frequency signal processing, the first radio-frequency signal processing module being a left-side temple of the XR communication terminal device, the second radio-frequency signal processing module being on a right-side temple of the XR communication terminal device;
• and
• a baseband signal processing module that is connected to the first and second radio-frequency signal processing modules via communication lines, and that is configured to perform baseband signal processing,
• wherein the first and second radio-frequency signal processing modules are selectively switched by the baseband signal processing module to perform a reception operation, and,
• wherein when the first radio-frequency signal processing module performs the reception operation, the second radio-frequency module is configured to retransmit a reception signal received by the first radio-frequency signal processing.
