Abstract: A terminal device first authenticates whether the terminal device has permission to sense a to-be-measured object. If the terminal device has sensing permission, the terminal device senses the to-be-measured object. If the terminal device has no sensing permission, the terminal device does not sense the to-be-measured object. In this way, privacy leakage of the to-be-measured object is prevented.

Abstract: A method includes: A transmitting end obtains at least two first signals through a first channel. The transmitting end sends the at least two first signals to at least two receiving ends based on a first antenna array. One receiving end corresponds to one first signal. Sub-bands corresponding to all of the at least two first signals are different. One receiving end corresponds to one beam. Directions of beams corresponding to all of the at least two receiving ends are different. The beam is formed by the first antenna array.

Abstract: A communication method and apparatus are provided. The communication apparatus communicates with a device to obtain first information that includes location information and/or motion information of the device, and senses an environment to obtain environment sensing information that includes location information and/or motion information of an object in the environment. The communication apparatus determines a first antenna panel and/or a second antenna panel different from the first antenna panel based on the first information and the environment sensing information, where the first antenna panel is configured to communicate with a first device, and/or is configured to send, to the first device, a signal for sensing information, the second antenna panel is configured to receive sensing signal from the first device. In the communication apparatus, sensing and communication functions can be implemented in a single hardware system, thereby decreasing a size of the communication apparatus and reducing the cost.

Abstract: A method and an apparatus for sensing and communication is provided. The method includes: a first device obtains a sensing parameter including a physical feature of a sensing target; configures a first frame based on the sensing parameter, and performs sensing on the first frame. The first frame includes M first time periods and N second time periods, both M and N are integers greater than or equal to 0, without being equal to 0 at the same time. The first device sends or receives a waveform of a communication signal during the first time period, and sends or receives a waveform of a sensing signal during the second time period. According to this application, spectral efficiency can be improved as sensing is performed without affecting communication thereby minimizing communication overheads, and sensing and communication occupy a same spectrum resource thereby meeting the requirements of sensing and communication.
