Terminal apparatus, base station apparatus, and communication method
A terminal apparatus includes a transmitter configured to transmit, in one uplink BWP of one serving cell, a first PUSCH corresponding to a configured uplink grant, and a receiver configured to receive, in one downlink BWP of the one serving cell, downlink control information to be used to schedule a second PUSCH on a PDCCH, in which, in a case that a duration of the first PUSCH overlaps a duration of the second PUSCH in the one uplink BWP, a first uplink symbol of the first PUSCH is expected to not be earlier than a first (next) uplink symbol at which a CP begins after a predetermined period of time after a last symbol of the PDCCH.
