Abstract
The disclosure relates to a random access method and device. The method includes: determining a first target uplink carrier among a plurality of uplink carriers corresponding to a target base station, the plurality of uplink carriers includes at least one supplementary uplink (SUL) carrier; transmitting a random access preamble to the target base station using the first target uplink carrier. In the technical solution, a terminal device can determine the first target uplink carrier used for transmitting the random access preamble among the plurality of uplink carriers corresponding to the target base station, and transmit the random access preamble to the target base station using the first target uplink carrier to initiate a random access, so that the random access is implemented in cells configured with the SUL carrier, thus the success rate of the random access is increased.
