ENHANCED SECRECY FOR ORTHOGONAL TIME FREQUENCY SPACE (OTFS) WAVEFORMS AT THE PHYSICAL LAYER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17835687 titled 'ENHANCED SECRECY FOR ORTHOGONAL TIME FREQUENCY SPACE (OTFS) WAVEFORMS AT THE PHYSICAL LAYER
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications. It focuses on transmitting secure downlink messages from a network entity to a user equipment (UE) in a wireless network.
- A transmitting device (network entity) sends an indication to the receiving device (UE) that a secure downlink message is scheduled for transmission.
- The UE responds by transmitting a sounding reference signal (SRS) to the network entity.
- The network entity uses the SRS to determine a channel estimate and construct interference based on the estimate.
- The secure downlink message is encoded using an orthogonal time frequency space (OTFS) precoding scheme.
- The network entity adds the constructed interference to the encoded secure downlink message over a slot duration.
- The network entity then transmits the encoded secure downlink message, including the added interference, to the UE.
- The UE decodes the encoded secure downlink message based on the OTFS precoding scheme.
Potential Applications
- This technology can be applied in various wireless communication systems, such as cellular networks, Wi-Fi networks, or satellite communications.
- It can enhance the security of downlink messages transmitted from network entities to user equipment, ensuring secure and reliable communication.
Problems Solved
- The technology addresses the need for secure downlink message transmission in wireless communication systems.
- By using an OTFS precoding scheme and adding interference, the technology provides a robust and secure method for transmitting sensitive information.
Benefits
- Improved security: The technology ensures that downlink messages are transmitted securely, protecting sensitive information from unauthorized access.
- Reliable communication: By using channel estimates and constructing interference, the technology enhances the reliability of downlink message transmission, reducing the risk of errors or data loss.
- Compatibility: The use of OTFS precoding scheme allows for compatibility with existing wireless communication systems, making it easier to implement this technology in various networks.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A transmitting device, such as a network entity, may transmit an indication (e.g., via control signaling) to a receiving device, such as a user equipment (UE), indicating that a secure downlink message is scheduled for transmission to the UE. The UE may transmit a sounding reference signal (SRS) to the network entity in response to the control signaling, and the network entity may determine a channel estimate and construct interference based on the channel estimate. The network entity may encode the secure downlink message according to an orthogonal time frequency space (OTFS) precoding scheme and may add the interference to the encoded secure downlink message over a slot duration. The network entity may transmit the encoded secure downlink message, including the added interference, to the UE. The UE may decode the encoded secure downlink message based on the OTFS precoding scheme.
