The present disclosure discloses example communication method and apparatus. One example method includes a first network device receiving first state information from at least one second network device, where the first state information indicates whether the at least one second network device is capable of providing a service in a next state. Third state information of the at least one second network device is received, where the third state information indicates a current state of the at least one second network device and includes user state information corresponding to at least a portion of a plurality of beamforming weight directions of the at least one second network device. A network topology is determined based on at least the first state information and the third state information, and after the first network device and the at least one second network device in a next state are networked.
