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 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.
