Abstract: This application provides communication methods and apparatuses. In an example method, a network device obtains a measurement result of a first signal, where antenna elements corresponding to the first signal are N of M antenna elements, and N is less than M; and when the measurement result of the first signal is better than a first threshold, the network device sends a second signal based on the N antenna elements.
