1. A user equipment, comprising:
receiving circuitry configured to:
receive a first radio resource control (RRC) message comprising first information used for a physical uplink shared channel (PUSCH) transmission corresponding to a configured grant, the first information comprising first parameters and a second parameter, the first parameters being for power control, the second parameter being for configuring a type of frequency resource allocation,
receive a second RRC message comprising second information used for a PUSCH transmission scheduled by a first physical downlink control channel (PDCCH) with cyclic redundancy check (CRC) scrambled by a cell-radio network temporary identifier (C-RNTI), the second information comprising a third parameter for configuring a type of frequency resource allocation, and
monitor a second PDCCH with CRC scrambled by a configured scheduling radio network temporary identifier (CS-RNTI), the second PDCCH being used for scheduling a PUSCH retransmission corresponding to the configured grant; and
transmitting circuitry configured to:
perform a PUSCH initial transmission corresponding to the configured grant by using the first parameters and the second parameter, and
perform, based on detection of the second PDCCH, the PUSCH retransmission corresponding to the configured grant by using the first parameters and the third parameter.
