摘要： This application provides a random access method and apparatus. The method includes: receiving, by a terminal, first indication information transmitted by a network device, where the first indication information is used to indicate a random access configuration index; determining, by the terminal, a random access resource based on the random access configuration index; determining, based on an association relationship between the random access resource and a downlink signal, a random access resource corresponding to the downlink signal; and transmitting a random access preamble to the network device based on the random access resource corresponding to the downlink signal. In this way, the random access resource is determined based on the random access configuration index indicated by the network device, and then the random access resource corresponding to the downlink signal is further determined based on the association relationship between the downlink signal and the random access resource. Therefore, a problem that the terminal blindly tries a random access resource when transmitting the random access preamble is avoided, and the network device side can receive the random access preamble on the random access resource corresponding to the downlink signal. This avoids a beam mismatch, and improves efficiency of a random access process.
