BACKGROUND To provide better quality of service for terminal devices, network devices typically need to transmit directional beams to the terminal devices, in other words, directions of main beams are aligned with the terminal devices. With development of communication technologies, there are more types of terminal devices. How to provide high-quality services for different types of terminal devices needs to be resolved.

In the foregoing solution, the operating mode corresponding to the first time unit is determined based on QoS requirements of different types of terminal devices, and the directional beam in the first time unit is formed based on the operating mode. The operating mode is the mode in which the first-type terminal device exclusively occupies the time unit, the mode in which the second-type terminal device exclusively occupies the time unit, or the mode in which the first-type terminal device and the second-type terminal device share the time unit, so that high-quality services can be provided for the different types of terminal devices based on the QoS requirements. In an example implementation, the determining, based on the first QoS requirement of the first-type terminal device and the second QoS requirement of the second-type terminal device, the operating mode corresponding to the first time unit includes: determining, based on the first QoS requirement and the second QoS requirement, that the operating mode corresponding to the first time unit is the mode in which the first-type terminal device exclusively occupies the time unit, where the QoS requirement of the first-type terminal device in the first time unit indicates that the first-type terminal device has a scheduling requirement in the first time unit, and the QoS requirement of the second-type terminal device in the first time unit indicates that the second-type terminal device has no scheduling requirement in the first time unit. In the foregoing solution, the scheduling requirement of the first-type terminal device is satisfied, and communication quality of service of the first-type terminal device can be improved. In addition, because the second-type terminal device has no scheduling requirement, communication quality of service of the second-type terminal device is not affected. In an example implementation, the forming the directional beam in the first time unit based on the operating mode includes: forming, based on an all-antenna array, a directional beam used for the first-type terminal device in the first time unit. In an example implementation, the determining, based on the first QoS requirement of the first-type terminal device and the second QoS requirement of the second-type terminal device, the operating mode corresponding to the first time unit includes: determining, based on the first QoS requirement and the second QoS requirement, that the operating mode corresponding to the first time unit is the mode in which the second-type terminal device exclusively occupies the time unit, where the QoS requirement of the first-type terminal device in the first time unit indicates that the first-type terminal device has no scheduling requirement in the first time unit,
