Summary:This application provides a beam management method and a related device. The method includes: A terminal device determines a first UE posture of the terminal device in a process in which the terminal device receives, by using a first receive beam, information sent by a network device, where the terminal device includes a plurality of receive beams; when the terminal device is changed from the first UE posture to a second UE posture, the terminal device determines a second receive beam based on a direction relationship between the plurality of receive beams and a direction change status during a change from the first UE posture to the second UE posture; and the terminal device receives, by using the second receive beam, the information sent by the network device. Based on this solution, when the terminal device posture changes, an appropriate receive beam can be selected to receive the information sent by the network device, to ensure performance of transmission between the terminal device and the network device. In addition, measurement frequency based on a reference signal can be reduced, power can be reduced, and link robustness can be improved.
