Abstract: A terminal apparatus includes: a receiver configured to receive an SS/PBCH block in an SS/PBCH block candidate; and a transmitter configured to transmit one random access preamble selected in a PRACH occasion. The terminal apparatus determines the PRACH occasion, based on a relationship between qSSB and the PRACH occasion.

The dSSB indicates an index of a DMRS for a PBCH in the SS/PBCH block. The QSSB indicates a number included in an MIB in the PBCH.
