Abstract: The present disclosure proposes a hierarchical beamforming method and a base station and a user equipment using the same. The method includes following steps. A network entry procedure is performed via a plurality of coarse beams by using a superframe header of a superframe corresponding to each of the coarse beams. In response to a success message associated with the network entry procedure being received, a network entry done message is transmitted by using a preferred coarse beam among the coarse beams. A user equipment (UE) connection is performed via a plurality of fine beams within a direction range of the preferred coarse beam, so as to determine a preferred fine beam by using a frame header of a basic frame corresponding to each of the fine beams, and perform a data packet transmission by using a packet transmission block of the basic frame corresponding to the preferred fine beam.
