Abstract: A random access/responding method and device are provided. In some embodiments, at least two random access preambles can be received before responding to random access of a terminal device, where each of the at least two random access preambles includes at least one sequence. In some embodiments, one random access preamble can be received before responding to random access of a terminal device, where the one random access preamble includes at least two sequences. The sequences in the received random access preambles can be checked. A successfully detected sequence or a random access preamble with the successfully detected sequence can then be responded to. In this way, responding to a plurality of successfully detected random access preambles or a plurality of successfully detected sequences included in one random access preamble is implemented.

Abstract: This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access.

Abstract: The present disclosure provides a downlink data transmission method, including: using a time-division multiplexing transmission mode in one transmission time interval; sending, by using a wide beam, a control signal to a user served in the current transmission time interval; and grouping users and sending data signals to different user groups by using different narrow beams. In one transmission time interval, time-division multiplexing is used, and a wide beam and a narrow beam are respectively used to transmit a control signal and a data signal. This can avoid a throughput bottleneck resulting from use of a transmission scheme that is based on frequency-division multiplexing only.
