Title:
TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/009821
Kind Code:
A1
Abstract:
A terminal receives, in a different frequency band which is different from a frequency band including one or a plurality of frequency ranges, a synchronization signal block (SSB), and determines, on the basis of the synchronization signal block, a transmission opportunity of a preamble through a random access channel. The terminal receives a synchronization signal block an index range of which is expanded, and when the index of the synchronization signal block is assumed to be i and the number of synchronization signal blocks is assumed to be M, determines, on the basis of i mod M, the transmission opportunity of the preamble through the random access channel.
