Abstract
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.
