A base station may indicate for a first device to transmit random information in the direction of an adverse device on at least partially overlapping time and frequency resources that are also used for receiving a downlink message from the base station. By transmitting the random information in the direction of the adverse device, the first device may cause entropy overhead to the adverse device, impacting an ability of the adverse device to decode portions of the downlink message transmitted to and intended for the first device. Accordingly, the first device may receive the downlink message and may concurrently transmit the random information in the direction of the adverse device on time and frequency resources that at least partially overlap with time and frequency resources used for receiving the downlink message based on receiving the indication from the base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Full-duplex communications and physical layer security","description":"Methods, systems, and devices for wireless communications are described.
