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 qSSB is given by one of a remainder obtained by dividing tSSB by QSSB or a remainder obtained by dividing dSSB by QSSB. The tSSB is a timing index of the SS/PBCH block candidate. 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.

Abstract: Terminal device initiates a COT-u at the beginning of an FFP-u after the channel is sensed to be idle and transmit an uplink transmission burst within the COT-u. In a case that the COT-u overlaps with a sensing slot for initiating an FFP-g with the one or more SS/PBCH blocks, the COT-u is terminated before the sensing slot. In a case that the COT-u does not overlap with the sensing slot, the COT-u is terminated after the sensing slot.

The HARQ-ACK information corresponding to the PDSCH scheduled by the PDCCH is included in the HARQ-ACK codebook.
