Description

Sensing method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a sensing method and apparatus. Background For sensing services, such as environment imaging or reconstructing an application scenario, reflection, scattering or diffraction on a sensing target when a signal sent by a User Equipment (UE) or a base station propagates in space can be used to sense a position or a shape of the sensing target in the environment. For example, for a sensing scene where the UE sends a signal and the base station receives a signal, the UE sends a sensing signal, the sensing signal reaches the base station after being reflected, scattered or diffracted by a sensing target, the base station can obtain a measurement result by measuring the sensing signal, and the sensing network element can perform sensing according to the measurement result. If the UE does not have the beamforming capability, the energy of the sensing signal sent by the UE is weaker, or the attenuation is larger in the transmission process, so that the base station cannot detect the transmission path with the sensing signal, and the sensing precision is reduced. Disclosure of Invention The embodiment of the application provides a sensing method and a sensing device, which are used for improving sensing precision. The sensing method and apparatus may be regarded as a communication method and apparatus, or a sensing communication integration method and apparatus. In a first aspect, a first sensing method is provided, which may be applied to a first device.

The method comprises the steps of receiving a first reference signal, and sending first information, wherein the first information is used for indicating a first antenna port, and the first antenna port is an antenna port for receiving the first reference signal on a first transmission path. In the embodiment of the present application, the terminal may send the first information to indicate the first antenna port corresponding to the first transmission path, which may be understood that the first information indicates the antenna port having the transmission path. So that the network device can detect the signal from the first antenna port and can perform sensing based on the signal. By the indication of the terminal, the network equipment can detect the signals sent from the antenna ports with transmission paths, so that the signal receiving success rate of the network equipment is improved, and the sensing precision is improved. In an alternative embodiment, the received power of the first reference signal received through the first antenna port on the first transmission path is greater than a first threshold. For example, if the received power of the first reference signal on one transmission path received by the first antenna port is greater than the first threshold, the terminal considers that the transmission path exists on the antenna port, or considers that the first reference signal is received on the antenna port, or considers that a sensing target exists in a direction corresponding to the antenna port, and the terminal can determine the antenna port on which the transmission path exists, or determine the antenna port possibly corresponding to the sensing target in this way. In an alternative embodiment, the first transmission path is a LoS path, or a transmission path where the first reference signal is reflected, scattered, or diffracted via the perception object. In an alternative embodiment, the first information is further used to indicate a second antenna port and/or a third antenna port, where the second antenna port is an antenna port that receives the first reference signal on the first transmission path, and the third antenna port is an antenna port that receives the first reference signal on the second transmission path. The terminal may determine that one or more antenna ports of the transmission path exist, and the terminal may indicate the one or more antenna ports to the network device through the first information. In an alternative embodiment, the first transmission path corresponds to one or more antenna ports, and the first antenna port is an antenna port with the largest received power of the received first reference signal on the first transmission path.
