The method includes: a termina receives physical random access channel (PRACH) configuration information from a base station of the unlicensed band, where the PRACH configuration information indicates a first time-domain resource occupied by a PRACH, located after a second time-domain resource occupied by a discovery signal including a synchronization signal block (SSB) and transmitted by the base station to the terminal; the terminal determines, based on the PRACH configuration information, the first time-domain resource occupied by the PRACH; the terminal determines, based on the time interval duration between the first time-domain resource and the second time-domain resource, a target channel access mechanism employed; the terminal performs channel detection according to the target channel access mechanism, and transmits random access information to the base station on the basis of a channel detection result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for random access on unlicensed band","description":"The present disclosure provides a method and device for random access.
