Abstract
In one aspect of the present invention, user equipment includes a reception unit configured to detect a synchronization signal or a physical broadcast channel from a base station; a resource selection unit configured to select, from resources determined based on configuration information for preamble transmission, a resource for transmitting a preamble according to the detected synchronization signal or the detected physical broadcast channel based on a mapping rule, with a period determined based on at least one of a period of a synchronization signal burst set that is a duration during which the synchronization signal or the physical broadcast channel can be transmitted and a period of a resource available for transmission of the preamble; and a transmission unit configured to transmit the preamble to the base station on the selected resource.
