摘要： This application provides a sensing signal transmission method and apparatus, so that transmission of a sensing signal can be coordinated by using a communication resource. This helps reduce interference between sensing nodes. The method includes: A terminal device sends a first message to a network device, where the first message includes information for requesting the network device to allocate a sensing resource to the terminal device. The network device receives the first message from the terminal device, allocates the sensing resource to the terminal device based on the first message, and sends a second message to the terminal device, where the second message includes the sensing resource allocated to the terminal device. The terminal device receives the second message from the network device, and sends a sensing signal on the allocated sensing resource.

摘要： An electronic device includes a transmission antenna and a reception antenna. The transmission antenna transmits a transmission wave. The reception antenna receives a reflection wave generated by reflection of the transmission wave. The electronic device detects an object based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflection wave. The electronic device includes a controller that determines how frequently to transmit the transmission wave in each of multiple segments of frequencies at which the transmission wave is transmitted in accordance with noise powers in the multiple segments of the frequencies.

摘要： A radar system and a terminal device are provided. The radar system includes a controller and at least two radar modules directly or indirectly connected to the controller. The at least two radar modules include a first radar module and a second radar module, and the first radar module and the second radar module implement time division multiplexing of the controller in a digital domain. Compared with an existing radar system, the radar system in this application can provide more transmit channels, more receive channels, and a larger antenna array size when the two radar systems include a same quantity of controllers.

摘要： An apparatus for is disclosed for mitigating radar-to-radar jamming within a shareable time slot. The apparatus includes a wireless transceiver configured to transmit a first radar signal during a first shareable time slot. The first radar signal has a start time that is delayed relative to a start time of the first shareable time slot by a first time delay. Additionally, the wireless transceiver is configured to receive a first receive signal during the first shareable time slot and detect a potential object based on the first receive signal. Furthermore, the wireless transceiver is configured to transmit, using the first antenna, a second radar signal during a second shareable time slot. The second radar signal has a start time that is delayed relative to a start time of the second shareable time slot by a second time delay. The second time delay is different than the first time delay based on the detection of the potential object.
