Application: Signal modification for control channel physical layer security (Patent ID: US20230336979A1)
Qualcomm Inc. has filed a patent related to wireless communication, focusing on securing physical control channel signals by modifying inputs or outputs of binary scrambling, modulation, or OFDM tone mapping based on a secrecy key. The transmitter device described in the patent is capable of generating a secured physical control channel signal and transmitting it to a receiver device. The transmitter device can initialize a scrambling sequence generator, mask scrambled bits, encrypt input bits, swap real and imaginary parts for modulation, and modify QAM or QPSK symbols based on the secrecy key to enhance security.
Furthermore, the patent also includes a receiver device that can retrieve information from a secured physical control channel signal by modifying inputs or outputs of OFDM tone mapping, demodulation, or binary unscrambling based on the secrecy key. The receiver device can initialize a scrambling sequence generator, unmask scrambled bits, decrypt output bits, swap real and imaginary parts for demodulation, and unscramble OFDM tones for mapping to QAM or QPSK symbols. These methods aim to enhance the security of wireless communication by utilizing secrecy keys to modify various aspects of signal processing in both transmitter and receiver devices.
