Abstract: Embodiments can provide a downlink-beam detection method and an apparatus. Under the method a terminal device can be notified by a network device of information about a broadcast beam. The network device can receive a detection result reported by the terminal device. The detection result may pertain to broadcast beam detection performed based on the information about the broadcast beam. the network device can then determine, based on the detection result, a downlink beam that needs to be swept during downlink-beam adjustment and that is used for data communication. This reduces signaling overheads.
