1. A terminal device comprising:
reception circuitry configured to sense a channel, receive Fixed Frame Period-u (FFP-u) configuration and Fixed Frame Period-g (FFP-g) configuration including Idle Period-g (IP-g) configuration; and
transmission circuitry configured to attempt to initiate a Channel Occupancy Time (COT-u) at a start of an FFP-u after the channel is sensed to be idle and transmit a configured grant Physical Uplink Shared Channel (PUSCH); wherein
a start of a time domain resource of the configured grant PUSCH is aligned with the start of the FFP-u; wherein
in a case that the FFP-u does not overlap with an IP-g of an FFP-g, the COT-u is initiated and the configured grant PUSCH is transmitted;
in a case that the FFP-u overlaps with the IP-g and the time domain resource of the configured grant PUSCH finishes before a start of the IP-g, the COT-u is initiated and the configured grant PUSCH is transmitted;
in a case that the FFP-u overlaps with the IP-g and the time domain resource of the configured grant PUSCH finishes at or after the start of the IP-g, the COT-u is not initiated and the configured grant PUSCH is not transmitted.
