Document Type and Number:
WIPO Patent Application WO/2019/174586
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a random access method and device, the method comprising: a second device receives at least one piece of SSB information sent by a first device, a resource of one PRACH corresponding to each piece of SSB information being located after a resource that carries the SSB information; and the second device, after using a resource of a first PRACH to perform listen before talk successfully, sends a random access preamble to the first device on the resource of the first PRACH, the resource of the first PRACH being a resource of a PRACH corresponding to first SSB information, and the first SSB information being one piece of SSB information of which the receive power is greater than a preset power threshold among the at least one piece of SSB information. The present invention reduces the delay of the second device in completing a random access process and improves the user experience.
