An embodiment of the present disclosure provides a method for accessing a node in a wireless communication system. The method comprises: sending a downlink broadcast signal to a device from a preset antenna port in a first time period by using an increased first transmit power, so as to allow the device to acquire downlink synchronization and acquire system information for random access, the downlink broadcast signal occupying part of a system bandwidth of a wireless communication system; receiving an uplink random access preamble from the device, and determining a downlink sending beamforming vector used for the device according to the random access preamble; and sending control information to the device in response to the uplink random access preamble. |
