摘要： This application discloses a beam direction adjustment method, which is applied to an antenna system including a microwave antenna and a radome, where the radome includes a liquid crystal array including M×N liquid crystal cells, and the method includes: obtaining an azimuth and/or a pitch angle of the microwave antenna; determining a target scanning angle of the microwave antenna based on the azimuth and/or the pitch angle; determining a first bias voltage value of the liquid crystal array based on the target scanning angle; and setting a voltage of the liquid crystal array to the first bias voltage value. Embodiments of this application further provide a corresponding apparatus. In the technical solutions of this application, when it is detected that the microwave antenna deviates to an angle, a transmission phase of a liquid crystal cell may be changed by adjusting a liquid crystal bias voltage of the liquid crystal array in the radome, to implement a corresponding phase layout, so that a beam of the microwave antenna scans the angle. In this way, automatic tracking and alignment are implemented.

摘要： Embodiments of this application disclose a user pairing method and a related device. The method includes: first, determining a first generation parameter of a first base sequence of a first user and a second generation parameter of a second base sequence of a second user, where the first base sequence is used to generate a first uplink reference signal of the first user, and the second base sequence is used to generate a second uplink reference signal of the second user; then, determining multiplexing evaluation information of the first base sequence and the second base sequence based on the first generation parameter and the second generation parameter, where the multiplexing evaluation information may include correlation strength between sequences and interference leakage width; afterwards, determining, based on the multiplexing evaluation information, whether the first user and the second user are successfully paired. Finally, when the first user and the second user are successfully paired, it is determined that the first user and the second user multiplex a same communication resource for communication. By using the embodiments of this application, flexibility of user pairing and spectral efficiency can be improved.

摘要： Embodiments of the present invention provide an antenna, a microwave device, and a communications system. The antenna includes an antenna body and a filter component. The antenna body has an antenna aperture and is configured to send and receive a radio frequency signal that passes through the antenna aperture, and the antenna body has an optical axis. The filter component is located at the antenna aperture and is disposed perpendicular to the optical axis, and is configured to filter an interference signal in the radio frequency signal. The filter component includes a filter layer and a support component, where the filter layer is formed by a lossy dielectric, and the support component is configured to support the filter layer, so that the filter layer forms a spatial structure similar to a shutter. The antenna provided in the embodiments of the present invention can suppress an antenna sidelobe, so that a problem is resolved that an interference suppression process affects a target service signal, and an application scenario is not limited.
