1. A terminal comprising:
a receiver that receives configuration of parameter sets for an uplink (UL) grant-free transmission whose resource is semi-statically configured;
a processor that controls the UL grant-free transmission based on the configuration of parameter sets activated by downlink control information (DCI); and
a transmitter that transmits a delivery confirmation for a reception of the DCI and performs the UL grant-free transmission,
wherein the transmitter determines, based on a format of the DCI, to transmit the delivery confirmation using a Medium Access Control Control Element (MAC CE),
the receiver receives a plurality of the configuration of parameter sets, and
when the plurality of the configuration of parameter sets are activated, the processor deactivates a configuration specified based on second DCI including information that specifies and deactivates one of the plurality of the configuration of parameter sets.
