Original Abstract Submitted
Embodiments of the present disclosure relate to a terminal device () and a communication system () comprising at least one terminal device (). The terminal device () comprises first circuitry () coupled to an antenna () and configured for a binary phase shift keying (BPSK) modulation based on a dual frequency signal received via the antenna. A first frequency part () of the dual frequency signal matches the antenna resonance frequency and is used for charging an energy storage, and a second frequency part () of the dual frequency signal is used for performing the BPSK modulation at a mismatched frequency of an antenna impedance. The terminal device () also comprises second circuitry () coupled to the first circuitry and configured to control a state of the first circuitry for performing the BPSK modulation. The terminal device can support BPSK backscatter with low complexity, cost, and a small size.
