Abstract: An antenna supports a first working mode and a second working mode. The antenna includes a first antenna subarray group, a second antenna subarray group, and a third antenna subarray group. The first antenna subarray group and the second antenna subarray group are used in the first working mode, and the first antenna subarray group and the third antenna subarray group are used in the second working mode.

Abstract: A beam weight obtaining method and an apparatus. An aggregation path is generated by using energy of a plurality of paths to help improve quality of a generated beam, thereby improving an SNR and a capacity of a terminal device. The method includes: a network device obtains a plurality of paths that meet a multipath aggregation condition, where the multipath aggregation condition includes one or more of the following conditions: a condition that every two paths in the plurality of paths need to meet in space, and a condition that every two paths in the plurality of paths need to meet in power. The network device determines aggregation information based on the plurality of paths, where the aggregation information includes information required by the network device to generate an aggregation path corresponding to the plurality of paths.

Abstract: This application provides example detection signal transmitting methods, detection apparatuses, and storage medium. One example method includes determining an orientation of a field of view of a detection apparatus. One of a plurality of anti-interference parameters can then be selected as a target anti-interference parameter based on the orientation of the field of view of the detection apparatus and according to a predefined rule, where the plurality of anti-interference parameters are determined according to the predefined rule. A detection signal can then be transmitted based on the target anti-interference parameter.

Abstract: A method for evaluating a parameter of an interfering signal includes: determining a slope of an interfering signal; setting the slope of the interfering signal as a slope of a first transmission signal; and determining a parameter of the interfering signal based on a feature of an echo signal of the first transmission signal.

Abstract: This application provides a beam generation method and an apparatus, to help improve precision of estimating a spatial direction of a terminal device. The method includes: A network device determines whether spatial directions of N beams converge to a spatial direction of a terminal device, where N is an integer greater than or equal to 3; and generates a data transmission beam when the spatial directions of the N beams converge to the spatial direction of the terminal device, where the data transmission beam is capable of being aligned with a center of coverage of the N beams, and that the spatial directions of the N beams converge to the spatial direction of the terminal device means that measurement results of the N beams meet a preset condition.
