1. A user equipment (UE) comprising:
receiving circuitry configured to receive a radio resource control (RRC) configuration comprising a first parameter used for defining a bit field size of an antenna ports field in a first downlink control information (DCI) format, a second parameter used for defining a bit field size of a carrier indicator field in the first DCI format, and a third parameter indicating a first allocation table used for defining a bit field size of a time domain allocation resource assignment in the first DCI format, wherein the first DCI format includes a 4-bit HARQ process number field; and
transmitting circuitry configured to perform, based on a detection of the first DCI format, a first physical uplink shared channel (PUSCH) transmission, wherein
in a case where the first PUSCH transmission is scheduled by the first DCI format, the first PUSCH transmission is performed according to the first parameter, the second parameter, and the third parameter, and
in a case where the first PUSCH transmission is a PUSCH transmission for which a plurality of configurations is configured, the first PUSCH transmission is performed according to one of the plurality of configurations, wherein the 4-bit HARQ process number field indicates that the one of the plurality of configurations is activated-a first physical uplink shared channel (PUSCH) transmission, wherein a configuration identifier of the first PUSCH transmission is indicated by the HARQ process number field, wherein
the receiving circuitry is further configured to receive an RRC configuration comprising a fourth parameter used for defining a bit field size of an antenna ports field in a second DCI format, a fifth parameter used for defining a bit field size of a carrier indicator field in the second DCI format, a sixth parameter used for defining a bit field size of a priority indicator field in the second DCI format, and a seventh parameter indicating a second allocation table used for defining a bit field size of a time domain allocation resource assignment in the second DCI format, and
the transmitting circuitry is further configured to perform, based on a detection of the second DCI format according to the fourth information, the fifth information, the sixth information and the seventh information, a second PUSCH transmission.
