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 communications method includes a terminal device receives broadcast information sent by a network device, where the broadcast information includes first information indicating N configuration parameters and a plurality of pieces of second information indicating Mi configuration parameters. Then, the terminal device determines configuration information of an ith reference signal based on some or all of the configuration parameters indicated by the first information and the Mi configuration parameters indicated by the ith piece of second information, where the configuration information of the ith reference signal includes Qi configuration parameters, and Qi is greater than or equal to N, and Qi is greater than or equal to Mi. The method reduces signaling overheads of the broadcast information.

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.
