Claim 3:
4. A system comprising a base station and a terminal, wherein:
the base station comprises:
a receiver that performs uplink (UL) reception from the terminal in at least one of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH), and
a transmitter that performs downlink (DL) transmission to the terminal in at least one of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH), and

the terminal comprises:
a transmitter that performs UL transmission in at least one of the PUCCH and the PUSCH, and
a receiver that performs DL reception in at least one of the PDCCH and the PDSCH,
wherein the transmitter of the terminal, when a frequency range is a first frequency range, does not perform the UL transmission until a first period corresponding to the first frequency range has elapsed after a last symbol of the DL reception,
the transmitter of the terminal, when the frequency range is a second frequency range, does not perform the UL transmission until a second period corresponding to the second frequency range has elapsed after the last symbol of the DL reception,
the first frequency range and the second frequency range are mutually different,
the first period and the second period are mutually different,
the second frequency range is a frequency band higher than 24 GHz, and
the first period and the second period are each defined by a multiplication of parameter NRX-TX and parameter TC, with at least one of the parameter NRX-TX and the parameter TC for the first frequency range being different from the at least one of the parameter NRX-TX and the parameter TC for the second frequency range.
