Abstract

Provided are a method and device for random access, which can implement flexible random access. The method includes: determining (210), by a terminal device, a first numerology to be used by a first message transmitted during a random access procedure; and receiving (220), by the terminal device using the first numerology, the first message transmitted by an access network device, wherein the determining (210), by the terminal device, the first numerology to be used by the first message transmitted during the random access procedure includes: determining, by the terminal device, the first numerology according to a frequency band of a frequency domain resource to be used for transmitting the first message and a correspondence between at least one frequency band and at least one numerology.
