Abstract: This application provides a random access method. In the method, a terminal device receives first DCI from a network device. The first DCI includes the first indication information, where the first indication information is used to indicate the type of the response information carried on a PDSCH. The PDSCH carries response information for a random access request initiated by the terminal device.

In this way, the terminal device demodulates the PDSCH indicated by the first DCI only when determining, based on the first indication information, that the PDSCH indicated by the received first DCI may belong to the terminal device.
