1. A terminal device comprising:
reception circuitry configured to sense a channel, receive a Fixed Frame Period (FFP)-g configuration including an Idle Period (IP)-g configuration and FFP-u configuration including IP-u configuration; and
transmission circuitry configured to initiate a Channel Occupancy Time (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; wherein
a maximum COT is a duration from the beginning of the COT-u to the beginning of an IP-u included in the FFP-u, and
in a case that the maximum COT overlaps with an IP-g and the beginning of the IP-g is before the beginning of the IP-u, the uplink transmission is stopped before or at the beginning of the IP-g.
