A method for receiving a random access preamble includes: sending, by a network device, a broadcast message, where the broadcast message is used to configure an NR uplink resource and an SUL resource, and the NR uplink resource and the SUL resource are used to send a random access preamble; sending, by the network device, first indication information and second indication information to a terminal device, where the first indication information is used to indicate the NR uplink resource or the SUL resource, and second indication information is used to indicate a first random access preamble; and receiving, by the network device, the first random access preamble on the resource indicated by the first indication information.
