Abstract
Embodiments provide a network access method and a device. In accordance with the method, a preamble sequence may be received by a second network device from a terminal device on a time-frequency resource occupied by the preamble sequence. A transmit beam may be determined for sending an access response message to the terminal device. The access response message can be sent to the terminal device using the transmit beam. The second access device can send the access response message to the terminal device through beamforming, so that a coverage area of the second access device can be enlarged, directivity of data sent to the terminal device can be improved, and a probability that the terminal device receives the access response message is improved. Therefore, a rate that the terminal device succeeds in accessing the second access device is improved.
