Abstract: This application discloses a delay reduction method and apparatus, applied to a random access process. The method includes: sending, by a terminal device, a message 1 to a network device, where the message 1 is a random access preamble; receiving, by the terminal device, a message 2 sent by the network device; and sending, by the terminal device, a message 3 to the network device, where a time gap between receiving the message 2 and sending the message 3 is set by the terminal based on a timing advance (TA) value. In an embodiment, the TA value is related to a message 1 format of the terminal device and a cell radius or subcarrier spacing supported by the message 1. In this solution, a TA value is reduced, and random access efficiency is improved.

Abstract: This application provides a method for transmitting a paging message, a terminal device, and a network device. The method includes: determining, by a terminal device, a target paging resource, where the target paging resource includes at least one of the following types of information: position information of a target paging occasion, position information of a target paging frame, and position information of a target monitoring window; and receiving, by the terminal device, a target paging message on the target paging resource, where the target paging message is a paging message sent by a network device to the terminal device. The terminal device and the network device can be used in a communications system applying a beamforming technology, so that the terminal device can receive a paging message sent by the network device to the terminal device.

Abstract: This application discloses a communications method and apparatus. The method includes: obtaining, by a terminal device, downlink synchronization signal block index information; receiving, by the terminal device, information used to indicate an association relationship between a random access resource RO and a synchronization signal block; and accessing, by the terminal device, a network device based on the information on an RO corresponding to the synchronization signal block index information. This application further discloses a corresponding apparatus. A time-frequency location of a random access resource associated with each downlink synchronization signal is indicated, so that the terminal device obtains, through downlink synchronization, a time-frequency location for sending an uplink random access signal, to avoid a blind attempt of the terminal device and a beam mismatch of the network device occurring when the network device receives a random access signal, thereby improving efficiency.

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.
